A plurality of speakers 17 are configured to perform so-called stereo sound reproduction or multi-channel sound reproduction for sounds related to effects.

[0020] Next, with reference to FIG. 3, the configuration of the game board 5 will be described. FIG. 3 is a front view of the game board 5. In the illustrated game board 5, a ball guide rail 18 for guiding the launched game balls is annularly mounted as a board surface partitioning member, and a substantially circular region surrounded by this ball guide rail 18 is a game area 19, and the four corners are non-game areas. The game area 19 is a space formed between the game board 5 and the transparent glass 6, and is an area where game balls can flow down.

[0021] At approximately the center of this game area 19, for example, in three (left, middle, right) display areas (symbol variation display areas), a liquid crystal display device (LCD) 20 capable of independently performing variation display operations (variation display and stop display) of a plurality of types of decorative symbols (for example, left symbol (corresponding to the left display area), middle symbol (corresponding to the middle display area), right symbol (corresponding to the right display area)) using numbers, characters, symbols, etc. is provided. This liquid crystal display device 20, under the control of an effect control board 41 described later, displays various effects as images in addition to the variation display operation of the decorative symbols.

[0022] Also, at the center of the game area 19, a center decoration 21 is provided so as to surround the periphery of the display surface of the liquid crystal display device 20 in a circumferential manner. The center decoration 21 is provided along the front side of the game board 5, protects the display surface of the liquid crystal display device 20 from the collision of game balls, and functions as a flow path distribution means that can distribute the flow path of game balls to the left and right depending on the launching strength or stroke length of the game balls. In the present embodiment, the center decoration 21 is disposed at approximately the center of the game area 19, and divides the game area 19 into a left game area 19a and a right game area 19b on the left and right sides respectively. Game balls launched by the launching device 44 with a launching strength less than a predetermined value will flow down through the left game area 19a, and game balls launched with a launching strength equal to or greater than the predetermined value will flow down through the right game area 19b.

[0023] The non-game area at the lower part of the game board 5 serves as various function display parts, and a special symbol display device 22a and a special symbol display device 22b using dot displays are provided. Note that various function display parts including the special symbol display devices 22a and 22b are shown enlarged in FIG. 6.

[0024] In the special symbol display devices 22a and 22b, a special symbol variation display game is executed by a variation display operation of "special symbols" expressed by dot displays. And in the above liquid crystal display device 20, in synchronization with the variation display of the special symbols by the special symbol display devices 22a and 22b, a decorative symbol is variably displayed by an image, and a decorative symbol variation display game is executed together with various preview effects (effect images).

[0025] In addition, a composite display device 22c composed of a dot display, similar to the special symbol display devices 22a and 22b, is arranged in the various function display parts. The reason for calling it "composite" is that it is a hold / short-time / high-probability composite display device (hereinafter simply referred to as "composite display device") having five display functions: display of the first special symbol (hereinafter, the first special symbol is referred to as "special symbol 1" and may be abbreviated as "special figure 1" in some cases), the second special symbol (hereinafter, the second special symbol is referred to as "special symbol 2" and may be abbreviated as "special figure 2" in some cases), display of the number of held balls of the normal symbol, and state notification during the short-time state and the high-probability state.

[0026] In addition, a composite display device 22d composed of a dot display is provided in the various function display parts. In this composite display device 22d, a round number display for notifying the specified number of rounds (maximum number of rounds) related to a big win is performed by a combination of lighting and extinguishing states of four LEDs. In addition, in the composite display device 22d, as a normal symbol display, a normal symbol variation display game is executed by a variation display operation of a normal symbol expressed by one LED. In the composite display device 22d, a right-handed display is performed by three LEDs. Note that the right-handed display indicates that it is more advantageous for the player to shoot the game ball toward the right game area 19b than when shooting the game ball toward the left game area 19a.

[0027] At the center of the game board 5 and below the liquid crystal display device 20, a first start port 23 is provided. Inside the first start port 23, a first start port detection sensor 23a (see FIG. 5) for detecting the passage of the game ball is provided. Also, in the right game area 19b, a second start port 24 is provided, and inside, a second start port detection sensor 24a (see FIG. 3) for detecting the passage of the game ball is provided.

[0028] The first start port 23 is a winning port related to the start condition of the variable display operation of the special symbol 1 in the special symbol display device 22a, and is configured as a fixed start port that does not have a start port opening / closing means (means for opening or expanding the start port). In the present embodiment, due to the action of the game ball dropping direction conversion member (for example, game nails, windmills, center ornaments 21, etc.) in the game area 19, for the game ball that has rolled from the left game area 19a to the first start port 23, the structure is such that it is easy for the ball to enter, while for the game ball that has rolled from the right game area 19b, the structure is such that it is difficult or impossible for the ball to enter.

[0029] The second start port 24 is a winning port related to the start condition of the variable display operation of the special symbol 2 in the special symbol display device 22b, and is configured as a variable start port whose opening and closing are controlled by the normal electric accessory 25. The normal electric accessory 25 is controlled to an open state that allows the game ball to enter the second start port 24 and a closed state that makes it difficult or impossible for the game ball to enter the second start port 24. In the present embodiment, the second start port 24 is provided in the right game area 19b, and only the game ball that has rolled from the right game area 19b can enter, but the game ball that has rolled from the left game area 19a may also be able to enter.

[0030] Above the second starting port 24, that is, on the upper side of the middle part of the right game area 19b, a normal symbol gate 26 through which the game balls can pass is provided. This normal symbol gate 26 is a winning port related to the variable display operation of the normal symbol in the composite display device 22d, and inside it, a normal symbol gate detection sensor 26a (see Fig. 5) for detecting the passing game balls is provided. In this embodiment, the normal symbol gate 26 is provided only in the right game area 19b, and only the game balls rolling in the right game area 19b can enter. However, the present invention is not limited to this, and it may be provided only in the left game area 19a, or may be provided in both.

[0031] Below the second starting port 24 in the right game area 19b, a first large winning port 27 and a second large winning port 28 are provided. The first large winning port 27 and the second large winning port 28 are arranged at positions where only the game balls rolling in the right game area 19b can enter. However, the first large winning port 27 and the second large winning port 28 may be arranged such that only the game balls rolling in the left game area 19a can enter, or may be arranged such that the game balls rolling in the left game area 19a and the right game area 19b can enter. The first large winning port 27 is controlled to open and close by the first special electric accessory 29. The first special electric accessory 29 is controlled to an open state that enables the game balls to enter the first large winning port 27 and a closed state that makes it difficult or impossible for the game balls to enter the first large winning port 27. The second large winning port 28 is controlled to open and close by the second special electric accessory 30. The second special electric accessory 30 is controlled to an open state that enables the game balls to enter the second large winning port 28 and a closed state that makes it difficult or impossible for the game balls to enter the second large winning port 28. Inside the first large winning port 27 and the second large winning port 28, a first large winning port detection sensor 27a and a second large winning port detection sensor 28a (see Fig. 5) for detecting the passing of the game balls are respectively provided.

[0032] Also, a plurality of general winning ports 31 are provided in the lower left and right of the game area 19, and inside each of them, a general winning port detection sensor 31a (see Fig. 5) for detecting the passing of the game balls is provided.

[0033] Also, a movable body accessory 50 that produces a visual effect is disposed at a position within the area of the game board that does not interfere with the rolling of the game balls. The gaming machine 1 of this example has two movable body accessories 50x and 50y as the movable body accessory 50. In the non-performance state, these movable body accessories 50x and 50y are arranged at positions (shielded positions) shielded by other members as viewed from the player facing the gaming machine 1, and are not visible to the player. In the performance state, these movable body accessories 50x and 50y are driven by accessory motors 53x and 53y (to be described later), and are displaced from the above-described shielded positions as illustrated in FIG. 4, so as to be in a state visible to the player. Here, as the displacement modes of the movable body accessories 50x and 50y, the displacement modes located on the liquid crystal display device 20 in the performance state are exemplified, but the displacement modes of the movable body accessory 50 are not limited to this, and various displacement modes can be considered.

[0034] In this example, the movable body accessory 50x is a movable body accessory 50 whose shielded position is below the liquid crystal display device 20 and is displaced upward from the shielded position in the performance state. On the other hand, the movable body accessory 50y is a movable body accessory 50 whose shielded position is above the liquid crystal display device 20 and is displaced downward from the shielded position in the performance state.

[0035] Also, in the gaming machine 1 of the present embodiment, when a game ball enters any of the various winning holes provided in the game area 19, the number of prize balls set for the winning hole into which the game ball has entered (for example, the first start hole 23 has 3 balls, the second start hole 24 has 1 ball, the first big winning hole 27 and the second big winning hole 28 have 15 balls, and the general winning hole 31 has 5 balls) is paid out from the game ball payout device 46 (see FIG. 5). The game balls that have not won in the above-described winning holes are discharged from the game area 19 through the out hole 32.

[0036] <2. Control Configuration of Gaming Machine> FIG. 5 is a block diagram showing the control configuration of the gaming machine 1. With reference to the block diagram of FIG. 5, a configuration (control configuration) for realizing the game operation control of the gaming machine 1 will be described. The gaming machine 1 of the present embodiment includes a main control board 40 that overall controls the control (game operation control) related to all game operations, an effect control board 41 that receives an effect control command from the main control board 40 and overall controls the execution control of the effects by the effect means, and a payout control board 42 that performs the payout control of prize balls.

[0037] [2.1 Main Control Board] The main control board 40 is equipped with a microprocessor incorporating a CPU (Central Processing Unit) 40a (main control CPU), and in addition to a control program describing the game operation control procedure, a ROM (Read Only Memory) 40b (main control ROM) that stores various data necessary for game operation control, and a RAM (Random Access Memory) 40c (main control RAM) that functions as a work area and buffer memory, and constitutes a microcomputer as a whole.

[0038] Although not shown in the figure, the main control board 40 also includes a CTC (Counter Timer Circuit) for realizing a periodic interrupt, a pulse output creation function (bit rate generator) at a fixed period, and a time measurement function, an interrupt controller circuit that exhibits an interrupt permission / interrupt prohibition function such as a timer interrupt that gives an interrupt signal to the CPU 40a, a reset circuit that can detect power-on, power-off, power abnormalities, etc., and output a system reset signal to reset the CPU 40a, a watchdog timer (WDT) circuit that monitors the abnormal operation of the control program, a designated area outside running prohibition (IAT) circuit that monitors whether the program is being correctly executed within a preset address range, and a counter circuit for generating a hardware random number within a certain range, etc.

[0039] The above counter circuit is configured to include a random number generation circuit that generates a random number and a sampling circuit that samples the random number value from the random number generation circuit at a predetermined timing, and operates as a 16-bit counter as a whole. The CPU 40a sends an instruction to the sampling circuit according to the processing state, thereby obtaining the value indicated by the random number generation circuit as a random number for jackpot determination (0 to 65535), and using the random number for jackpot determination in the jackpot lottery (win / loss lottery). Note that the random number for jackpot determination is obtained by adding a software random number value generated by appropriate software processing to prevent cheating such as aiming for a win and a hardware random number value in order to prevent cheating such as aiming for a win.

[0040] The main control board 40 is connected to a first start port detection sensor 23a that detects the entry of a game ball into the first start port 23, a second start port detection sensor 24a that detects the winning of the second start port 24, a normal symbol gate detection sensor 26a that detects the passage of the normal symbol gate 26, a first big winning port detection sensor 27a that detects the winning of the first big winning port 27, a second big winning port detection sensor 28a that detects the winning of the second big winning port 28, a general winning port detection sensor 31a that detects the winning of the general winning port 31, and an OUT monitoring sensor 32a that detects the game balls (out balls) discharged from the game area 19, and the main control board 40 is capable of receiving the detection signals output from these sensors. The main control board 40 can grasp which winning port the game ball has entered based on the detection signals from the respective sensors.

[0041] In addition, the main control board 40 is connected to a normal electric accessory solenoid 25a that operates a normal electric accessory 25 that opens and closes the second start port 24, a first special electric accessory solenoid 29a that operates a first special electric accessory 29 that opens and closes the first big winning port 27, and a second special electric accessory solenoid 30a that operates a second special electric accessory 30 that opens and closes the second big winning port 28, and the main control board 40 is capable of transmitting control signals for controlling these.

[0042] The main control board 40 is connected to a special symbol display device 22a and a special symbol display device 22b, and the main control board 40 is capable of transmitting control signals for controlling the display of the special symbols 1 and 2. In addition, a composite display device 22c and a composite display device 22d are connected to the main control board 40, and the main control board 40 is capable of transmitting a control signal for controlling the display of various information displayed on the composite display device 22c and the composite display device 22d.

[0043] A RAM clear switch 34 is connected to the main control board 40, and the main control board 40 is capable of receiving a detection signal from the RAM clear switch 34. The RAM clear switch 34 is provided at a predetermined position inside the gaming machine 1. For example, it is arranged on the main control board 40.

[0044] The RAM clear switch 34 is, for example, a push-button type switch for instructing the initialization of a predetermined area of the RAM 40c. The RAM clear switch 34 is turned ON / OFF in response to the operation of a RAM clear button provided so as to be operable when the front frame 4 is open.

[0045] In addition, a performance indicator 35 is connected to the main control board 40. The performance indicator 35 is configured to have, for example, a 7-segment display, and functions as a display means capable of displaying performance information to be described later. The performance indicator 35 is mounted, for example, at a visible position on the main control board 40. The main control board 40 is capable of transmitting a control signal for causing the performance indicator 35 to display performance information.

[0046] A payout control board 42 is connected to the main control board 40. When it is necessary to pay out prize balls, the main control board 40 is capable of transmitting a control command regarding payout (a payout control command specifying the number of prize balls) to the payout control board 42.

[0047] In addition, a frame external centralized terminal board 43 is connected to the main control board 40 via the payout control board 42, and the main control board 40 is capable of transmitting predetermined gaming information (for example, jackpot information, prize ball number information, symbol variation execution information, etc.) to a hall computer HC provided outside. The hall computer HC is an information processing device (computer device) that monitors game information from the main control board 40 and comprehensively manages the operating status of the gaming machines in the pachinko hall.

[0048] Connected to the payout control board 42 are a launch control board 45 that controls the launcher 44 and a game ball payout device 46 that pays out game balls. Further, a ball lending machine 70 is connected to the payout control board 42. The ball lending machine 70 is provided outside the gaming machine 1 and executes processes for causing the payout control board 42 to perform a ball lending operation. The main roles of the payout control board 42 include receiving a payout control command from the main control board 40, controlling the bonus ball payout of the game ball payout device 46 based on the payout control command, transmitting a status signal to the main control board 40, and controlling the payout control board 42 for a ball lending operation based on the communication result with the ball lending machine 70.

[0049] The game ball payout device 46 is provided with a replenishment depletion detection sensor 46a that detects a shortage in the supply of game balls and a ball counting sensor 46b that detects the game balls (bonus balls) being paid out, and the payout control board 42 is capable of receiving these respective detection signals. Also, the game ball payout device 46 is provided with a payout motor 46c that drives a ball payout mechanism section (not shown) for paying out game balls, and the payout control board 42 is capable of transmitting a control signal for controlling the payout motor 46c.

[0050] Connected to the payout control board 42 are a full cup detection sensor 47 that detects a state where the upper tray 10 is full of game balls and a front door open sensor 48 that detects the open state of the front frame 2.

[0051] The payout control board 42 can transmit various status signals to the main control board 40 based on detection signals from the full detection sensor 47, the front door open sensor 48, the replenishment shortage detection sensor 46a, and the ball counting sensor 46b. These status signals include a ball jam signal indicating a full state, a door open signal indicating that at least the front frame 2 is open, a replenishment shortage signal indicating a shortage in the supply of game balls from the game ball payout device 46, a counting error signal indicating a shortage in the payout of bonus balls or an abnormality in the ball counting sensor 46b, a payout completion signal indicating that the payout operation has been completed, etc., and is configured to be able to transmit various status signals. Based on these status signals, the main control board 40 monitors the open state of the front frame 2 (door open error), whether the payout operation of the game ball payout device 46 is normal (replenishment shortage error), the full state of the upper tray 10 (ball jam error), etc.

[0052] Also, the payout control board 42 can transmit a permission signal to permit firing to the firing control board 45. Based on the output of the permission signal from the payout control board 42, the firing control board 45 controls the energization of a firing solenoid (not shown) provided in the firing device 44 to realize the firing operation of the game ball by operating the firing operation handle 15. Specifically, the firing operation is permitted on the condition that a firing permission signal is output from the payout control board 42 (firing permission signal ON state), it is detected by a touch sensor (not shown) provided on the firing operation handle 15 that the player is touching the handle, and a firing stop switch (not shown) provided on the firing operation handle 15 is not operated. Therefore, when the firing permission signal is not output (firing permission signal OFF state), even if the firing operation handle 15 is operated, the firing operation is not executed and the game ball is not fired. Also, the firing intensity of the game ball can be changed according to the operation amount of the firing operation handle 15. When the payout control board 42 detects the above-mentioned ball jam error, it transmits a ball jam signal to the main control board 40 and stops the output of the firing permission signal to the firing control board 45 (firing permission signal OFF), and performs control to stop the shooting operation until the full state of the upper tray 10 is resolved. In addition, the payout control board 42 outputs an emission permission signal to the emission control board 45 on the condition that emission permission is instructed by the main control board 40.

[0053] (Regarding performance display) The main control board 40 is capable of transmitting a control signal for causing the performance display 35 to display predetermined performance information. The performance information is information that the pachinko parlor and related agencies want to check. Representative examples include information regarding the presence or absence of illegal winning balls such as excessive winning balls for the gaming machine 1 and the original ball output performance of the gaming machine 1. Therefore, unlike preview effects and the like, the performance information itself is information that has no direct relation to the progress of the game when the player enjoys the game.

[0054] For this reason, the performance display 35 is provided at a position where the display information can be visually recognized inside the gaming machine 1, for example, on the main control board 40, the payout control board 42, the emission control board 45, the relay board, the effect control board 41, or on the board case (protective cover for protecting the board), when the front frame 2 is in an open state.

[0055] Here, the following specific information can be adopted as the performance information. (1) Information (specific ratio information) based on the value (α / β) obtained by dividing the total number of payouts (specific total number of winning balls: α) paid out due to winning during a specific state by the total number of out balls (specific number of out balls: β) discharged from the game area 19 during the specific state can be adopted as the performance information. The above-mentioned "total number of payouts" is the total value of the game balls (winning balls) paid out when winning at the winning ports (the first start port 23, the second start port 24, the general winning port 31, the first large winning port 27, the second large winning port 28). Also, as for which state to adopt as the specific state, it can be appropriately determined according to what performance information under what state is to be grasped. In the case of this embodiment, any of a plurality of gaming states and during a jackpot game can be adopted. Also, a plurality of types of states may be measurement targets. For example, all gaming states except during a jackpot game, etc., and the types to be measurement targets can be appropriately determined. Also, the total payout number may be the one obtained by excluding one or a plurality of specific winning ports from the measurement targets (total payout number excluding specific winning ports). For example, among each winning port, the one obtained by excluding the first major winning port 27 and the second major winning port 28 from the measurement targets may be used as the total payout number.

[0056] (2) Otherwise, only any one of the total payout number, the total payout number excluding specific winning ports, and the total number of out balls may be measured, and the measurement result may be used as performance information.

[0057] In this embodiment, the total payout number during the normal state (normal payout number) and the total number of out balls during the normal state (normal out ball number) are measured in real time, and the value obtained by multiplying the value obtained by dividing the normal payout number by the normal out ball number by 100 (the value calculated by normal payout number ÷ normal out ball number × 100) is displayed as performance information (hereinafter referred to as "normal ratio information"). Note that the displayed value at this time is the value obtained by rounding off the first decimal place. Therefore, each data of the normal payout number, the normal out ball number, and the normal ratio information is stored (memorized) in the corresponding area (specific total prize ball number storage area, specific out ball number storage area, specific ratio information storage area) of the RAM 40c. However, it does not simply measure permanently and display the performance information. When the total out ball number reaches a predetermined specified number (for example, 60,000), the measurement is once terminated. This specified number is not the total out ball number in the normal state, but the total out ball number during all game states (including the winning games) (hereinafter referred to as the "total state out ball number"). This total state out ball number is also measured in real time and stored in the corresponding area (total state out ball number storage area) of the RAM 40c. Hereinafter, for the convenience of explanation, the specific total prize ball number storage area, the specific out ball number storage area, the specific ratio information storage area, and the total state out ball number storage area are abbreviated as the "measurement information storage area".

[0058] Then, the normal ratio information at the end time is stored in a predetermined area (performance display storage area) of the RAM 40c (store the current normal ratio information), and then, after clearing the measurement information storage area (normal payout number, normal out ball number, and total state out ball number), the measurement is started again (start the measurement of the normal payout number, normal out ball number, normal ratio information, and total state out ball number). And on the setting / performance display 35, the previous normal ratio information (measurement history information) and the currently measured normal ratio information are displayed. Note that not only the previous information but also the history such as the information of the game before last and the game before that (three games before) can be configured to be displayed, and it can be appropriately determined how many games before the information is displayed.

[0059] (Effect control command) The main control board 40 can transmit various effect control commands including information related to the special symbol variation display game and information related to errors, etc. to the effect control board 41 according to the processing state. However, in order to prevent fraud such as cheating behavior, the main control board 40 is configured for one-way communication that only transmits a signal to the effect control board 41 and cannot receive a signal from the effect control board 41.

[0060] Here, the production control command is defined by a two-byte configuration consisting of a one-byte-long mode (MODE) and also a one-byte-long event (EVENT). To distinguish between MODE and EVENT, Bit7 of MODE is set to ON and Bit7 of EVENT is set to OFF. When transmitting these pieces of information as valid, a strobe signal is output corresponding to each of the mode (MODE) and the event (EVENT). That is, when there is a command to be transmitted, the CPU 40a (main control CPU) sets and outputs the mode (MODE) information for transmitting the command to the production control board 41, and transmits the first strobe signal after a predetermined time has elapsed from this setting. Further, after a predetermined time has elapsed from the transmission of this strobe signal, the event (EVENT) information is set and output, and the second strobe signal is transmitted after a predetermined time has elapsed from this setting. The strobe signal is controlled to be in an active state by the CPU 40a for a predetermined period during which the CPU 41a (production control CPU) can surely receive the command.

[0061] [2.2 Production Control Board] The production control board 41 is mainly composed of a microcomputer equipped with a microprocessor incorporating the CPU 41a, and also includes a ROM 41b storing production data required for production control processing, and a RAM 41c functioning as a work area and a buffer memory. In addition, an acoustic control unit (sound source IC), an RTC (Real Time Clock) function unit, a counter circuit, an interrupt controller circuit, a reset circuit, a WDT circuit, etc. are provided to control the entire production operation.

[0062] Based on the production control program and the production control command received from the main control board 40, the CPU 41a performs arithmetic processing for various production operations and controls each production means. The production means, in the case of the gaming machine 1 of the present embodiment, are the liquid crystal display device 20, the light display device 16a, the acoustic generating device 17a, and the movable body accessory 50.

[0063] The ROM 41b stores a control program for the rendering operation by the CPU 41a and various data necessary for the rendering operation control. The RAM 41c is used as a work area for the CPU 41a to perform various arithmetic processes, a table data area, a buffer area for various input / output data and processing data, and the like. Note that the rendering control board 41 is configured, for example, with a one-chip microcomputer and its peripheral circuits, but various configurations of the rendering control board 41 are conceivable. For example, in addition to the microcomputer, an interface circuit with each unit, a random number generation circuit for generating a lottery random number for rendering, a CTC for various time counting, a watchdog timer (WDT) circuit, and an interrupt controller circuit that gives an interrupt signal to the CPU 41a may be provided.

[0064] The main roles of this rendering control board 41 are to receive a rendering control command from the main control board 40, select and determine a rendering based on the rendering control command, control the display of the liquid crystal display device 20 (supply display data), control the voice output of the acoustic generating device 17a, control the light emission of the light display device 16a (LED), control the operation of the movable object accessory 50, and the like.

[0065] Since this rendering control board 41 also has a function as a control device for the liquid crystal display device 20, the rendering control board 41 also has functions as a so-called VDP (Video Display Processor), an image ROM, and a VRAM (Video RAM), and the CPU 41a also functions as a liquid crystal control unit. The VDP refers to a function that controls all video output processes such as image expansion processing and image drawing. The image ROM refers to a memory in which image data for the VDP to perform image expansion processing is stored. The VRAM is an image memory area that temporarily stores the image data developed by the VDP.

[0066] The performance control board 41, with these configurations, generates various image data based on the performance control commands from the main control board 40 and outputs it to the liquid crystal display device 20. As a result, various performance images are displayed on the liquid crystal display device 20.

[0067] Also, the performance control board 41 has an acoustic control unit for the acoustic generating device 17a including a plurality of speakers 17. The acoustic signal output by the acoustic control unit is amplified by the amplifier unit 17b and supplied to the speaker 17. In addition, the performance control board 41 is connected to a lamp driver unit 16b that functions as a light display control unit for the light display device 16a including the decorative lamp 16 and various LEDs, and a motor drive control unit 51 that controls the operation of the movable object accessory 50 (in this example, the movable object accessories 50x, 50y). The performance control board 41 gives instructions to these lamp driver unit 16b and motor drive control unit 51 to control the light display operation by the light display device 16a and the operation of the movable object accessory 50.

[0068] Here, in the gaming machine 1, there is a movable object accessory motor group 53 composed of a plurality of accessory motors (the accessory motors 53x, 53y described later) for driving each movable object accessory 50, and a motor driver group 52 composed of a plurality of motor drivers (the motor drivers 52x, 52y described later) for performing drive control for each accessory motor in the movable object accessory motor group 53. However, in the gaming machine 1 of this embodiment, the performance control board 41 does not directly control each motor driver in the motor driver group 52, but adopts a configuration in which the operation of each motor driver is controlled via the motor drive control unit 51. Details of the movable object accessory control as an embodiment performed via the motor drive control unit 51 will be described later again.

[0069] Here, in this embodiment, for each accessory motor in the movable object accessory motor group 53, for example, a bipolar motor is adopted.

[0070] The origin switch group 54 comprehensively represents a plurality of origin switches for determining whether each movable object device 50 is at the origin position. The position sensor group 55 comprehensively represents position sensors (position sensors 55x and 55y described later) provided for each movable object device 50 to detect the operating position (for example, the amount of movement from the origin position) of the movable object device 50.

[0071] In the gaming machine 1 of the present embodiment, the detection signals from the respective position sensors in the position sensor group 55 are input to the motor drive control unit 51 instead of the effect control board 41. As will be described later, the motor drive control unit 51 can perform control such as moving the movable object device 50 to the sensor position and stopping it in response to an input from the position sensor, based on an instruction from the effect control board 41.

[0072] In the origin switch group 54, each origin switch is composed of, for example, a photo interrupter or the like, and detects whether the corresponding movable object device 50 is at the origin position. The origin position is, for example, the shielding position described with reference to FIG. 4. The effect control board 41 can determine whether the movable object device 50 is at the origin position based on the detection signal of the origin switch in the origin switch group 54. Based on the result of this determination, the effect control board 41 can perform an origin return process to return each movable object device 50 to the origin position.

[0073] In addition, operation detection switches for the effect buttons 14a, cross keys 14b, and decision button 14c shown as the operation unit 14 are connected to the effect control board 41, and the effect control board 41 can receive the operation detection signals from the effect buttons 14a, cross keys 14b, and decision button 14c, respectively.

[0074] Furthermore, on the effect control board 41, there is provided a handle sensor 56 (touch sensor) for detecting whether or not the firing operation handle 15 shown in FIG. 1 is being touched by the player. Based on the detection information of this handle sensor 56, the effect control board 41 can determine whether or not the firing operation handle 15 is being touched by the user.

[0075] Based on the effect control commands sent from the main control board 40, the effect control board 41 selects (determines) an effect pattern by lottery or uniquely from among a plurality of types of prepared effect patterns, and controls various effect means at the necessary timing to present the target effect. As a result, display of an effect image by the liquid crystal display device 20 corresponding to the effect pattern, reproduction of sound from the speaker 17, and lighting and blinking drive of the decorative lamp 16 and the LED are realized, and various effect patterns (such as a decorative pattern variation display operation and a preview effect) are developed in time series, thereby realizing a "performance scenario" in a broad sense.

[0076] Here, regarding the effect control command, the effect control board 41 (CPU 41a) generates an interrupt process based on the input of the above-described strobe signal transmitted by the main control board 40 and performs its reception and analysis. Specifically, the CPU 41a executes a control program for command reception interrupt processing based on the input of the above-described strobe signal, and in the interrupt process realized thereby, acquires the effect control command and analyzes the command content. At this time, when an interrupt occurs based on the input of the strobe signal, the CPU 41a interrupts the process and performs the command reception interrupt process even if it is in the middle of executing an interrupt process based on another interrupt (a timer interrupt process that is executed periodically), and preferentially performs the command reception interrupt process even if another interrupt occurs simultaneously.

[0077] <3. Outline description of the operation> Next, an outline of the gaming operation of the gaming machine 1 realized by the above control configuration (FIG. 5) will be described.

[0078] [3.1 Game state] In the gaming machine 1 according to the present embodiment, in addition to the jackpot game which is a special game state, a plurality of types of game states can be set. For the sake of easy understanding of the present embodiment, first, various game states will be described.

[0079] In the gaming machine 1 of the present embodiment, the game progresses in any of the game states in which either the low probability state or the high probability state is combined with either the non-time shortening state or the time shortening state.

[0080] The low probability state is a state in which the winning probability of the jackpot lottery described later is relatively low, and the high probability state is a state in which the winning probability of the jackpot lottery is relatively high. The non-time shortening state is a state in which it is relatively difficult for game balls to enter the second starting port 24, and the time shortening state is a state in which it is relatively easy for game balls to enter the second starting port 24. In the present embodiment, in the time shortening state, the opening time of the second starting port 24 when winning the general pattern winning lottery described later is set longer than that in the non-time shortening state. However, if game balls are more likely to enter the second starting port 24 in the time shortening state than in the non-time shortening state, for example, the winning probability of the general pattern winning lottery may be increased or the variation time of the normal symbol may be shortened in the time shortening state compared to the non-time shortening state.

[0081] In the present embodiment, the "normal state" refers to the low probability state and the non-time shortening state, which corresponds to the initial state.

[0082] [3.2 Symbol variation display game] (Regarding special symbol reservation) In the gaming machine 1, when a game ball enters the first starting port 23 or the second starting port 24, that is, when a detection signal is input from the first starting port detection sensor 23a or the second starting port detection sensor 24a, random numbers (jackpot determination random numbers, special symbol determination random numbers, variation pattern random numbers) related to the special symbol variation display game described later are acquired, and these random numbers are stored as reservation data in the special symbol reservation storage area of the RAM 40c up to the maximum reservation storage number which is a predetermined upper limit value (for example, a maximum of 4). This special figure reserved memory area is provided with a special figure reserved memory area corresponding to the special figure 1 side and the special figure 2 side, that is, a special figure 1 reserved memory area and a special figure 2 reserved memory area.

[0083] In these special figure reserved memory areas, a reserved 1 memory area to a reserved n memory area (n is the maximum number of reserved memories: in this embodiment, n = 4) are provided, and each can store reserved data corresponding to the maximum number of reserved memories. Note that the maximum number of reserved memories in the special figure 1 reserved memory area and the special figure 2 reserved memory area is not particularly limited. Also, all or part of the maximum number of reserved memories for each symbol may be different, and the number can be appropriately determined according to the game properties. The game balls related to the reserved data stored in this special figure reserved memory area are also referred to as "reserved balls". In order to clarify the number of these reserved balls to the player, the dot display corresponding to the number of reserved balls of special figure 1 and special figure 2 in the composite display device 22c is lit, or the reserved display provided as an icon image on the screen by the liquid crystal display device 20 is lit.

[0084] (Special symbol variation display game) In the gaming machine 1 of this embodiment, based on a predetermined start condition, specifically, when a game ball enters (wins) the first start port 23 or the second start port 24, a "big win lottery" by random number lottery is performed on the main control board 40. Based on the lottery result of the big win lottery, the main control board 40 variably displays special symbol 1 and special symbol 2 on the special symbol display devices 22a and 22b to start a special symbol variation display game. After a predetermined variation time has elapsed, the result is displayed on the special symbol display devices 22a and 22b, thereby ending the special symbol variation display game. Note that, unless particularly necessary, "special symbol 1" and "special symbol 2" are simply referred to as "special symbol" (abbreviated as "special figure" in some cases).

[0085] Here, in the present embodiment, the jackpot lottery in the special drawing of FIG. 1 based on winning the first start port 23 and the jackpot lottery in the special drawing of FIG. 2 based on winning the second start port 24 are carried out separately and independently. For this reason, the jackpot lottery result of the special drawing of FIG. 1 is displayed on the special symbol display device 22a, and the jackpot lottery result of the special drawing of FIG. 2 is displayed on the special symbol display device 22b. Specifically, in the special symbol display device 22a, on the condition that a game ball enters the first start port 23, the special drawing of FIG. 1 is variably displayed to start the first special symbol variable display game. On the other hand, in the special symbol display device 22b, on the condition that a game ball enters the second start port 24, the special drawing of FIG. 2 is variably displayed to start the second special symbol variable display game. When the special symbol variable display game in the special symbol display device 22a or the special symbol display device 22b is started, after a predetermined variable time has elapsed, if the jackpot lottery result is "jackpot", it is in a predetermined "jackpot" mode, and in other cases, it is in a predetermined "miss" mode, and the special symbol being variably displayed stops being displayed, whereby the game result (jackpot lottery result) is notified.

[0086] For the sake of convenience of explanation, the first special symbol variable display game on the special symbol display device 22a side is referred to as "special symbol variable display game 1", and the second special symbol variable display game on the special symbol display device 22b side is referred to as "special symbol variable display game 2". Also, "special symbol variable display game 1" and "special symbol variable display game 2" are simply referred to as "special symbol variable display game".

[0087] When the jackpot lottery result becomes "jackpot", that is, when the special symbol variable display game ends and as a result, the special symbol stops being displayed in the "jackpot" mode on the special symbol display device 22a or the special symbol display device 22b, then, a special game state (jackpot game) more advantageous to the player than during the special symbol variable display game occurs. As will be described in detail later, in the big win game, after the pre-opening interval time (opening time) for notifying the start of the big win game has elapsed, after the first big winning opening 27 or the second big winning opening 28 is opened, when a predetermined time (maximum opening time: for example, 29.8) has elapsed, or when the number of game balls that have entered the first big winning opening 27 or the second big winning opening 28 reaches a predetermined number (maximum winning number), a "round game" in which the first big winning opening 27 or the second big winning opening 28 is closed is repeated a predetermined number of prescribed rounds (for example, a maximum of 10 rounds). Then, after the prescribed number of rounds ends, when the post-opening interval time (ending time) for notifying the end of the big win game has elapsed, the big win game ends. Note that the "s" after the numbers represents "seconds".

[0088] (Decoration symbol variation display game) Also, when the above-mentioned special symbol variation display game is started, accordingly, a decoration symbol (an effect game symbol) is variably displayed on the liquid crystal display device 20 to start a decoration symbol variation display game, and various effects are developed accordingly. When the special symbol variation display game ends, the decoration symbol variation display game also ends, and a predetermined special symbol indicating the big win lottery result is displayed on the special symbol display devices 22a and 22b, and a decoration symbol reflecting the big win lottery result is derived and displayed on the liquid crystal display device 20. That is, the result of the special symbol variation display game is reflected and displayed by the effect decoration symbol variation display game including the variable display operation of the decoration symbol.

[0089] Therefore, for example, when the result of the special symbol variation display game is a "big win" (when the big win lottery result is a "big win"), an effect reflecting the result is developed in the decorative symbol variation display game. And when the special symbols on the special symbol display devices 22a and 22b stop displaying in a display mode indicating a big win (for example, the 7-segment display shows "7"), on the liquid crystal display device 20, in each of the display areas of "left", "middle", and "right", the decorative symbols stop displaying in a display mode reflecting the "big win" (for example, in each of the display areas of "left", "middle", and "right", the three decorative symbols are in the display state of "7", "7", "7").

[0090] Regarding the information necessary for the execution of the above decorative symbol variation display game, first, based on the fact that a game ball has entered the first start port 23 or the second start port 24, specifically, when the game ball is detected by the first start port detection sensor 23a or the second start port detection sensor 24a and the start condition (the start condition regarding the special symbol) is satisfied, a big win lottery is conducted to draw whether it is a "big win" or a "miss", and a symbol lottery is conducted to draw the type of the special symbol (big win type, miss type) that will finally stop displaying. Based on the lottery results, the variation pattern of the special symbol is determined. In the symbol lottery, if the big win lottery result is a "big win", one of the multiple big win types is determined by lottery, and if it is a "miss", one of the multiple miss types is determined by lottery. However, there may be only one big win type and one miss type, and in that case, it may be determined without conducting a lottery. Then, the main control board 40 transmits a "variation pattern specification command" including at least the information on the variation pattern of the special symbol (variation pattern information (for example, information regarding the big win lottery result and the variation time of the special symbol, etc.)) as an effect control command for specifying the processing state to the effect control board 41 side. Thereby, the basic information required for the decorative symbol variation display game is sent to the effect control board 41.

[0091] The variable pattern information of the special symbol can include information specifying the occurrence of a specific pre-announcement effect (for example, the "reach effect" or "pseudo-consecutive effect" described later). Specifically, the variable pattern of the special symbol is roughly classified into a "winning variable pattern" in the case of a win and a "losing variable pattern" in the case of a loss according to the jackpot lottery result. These variable patterns include, for example, a'reach variable pattern' that specifies the occurrence of a reach effect, a 'normal variable pattern' that does not specify the occurrence of a reach effect, a 'pseudo-consecutive with reach variable pattern' that specifies the occurrence of a pseudo-consecutive effect and a reach effect (duplicate occurrence), a 'pseudo-consecutive with normal variable pattern' that specifies the occurrence of a pseudo-consecutive effect and does not specify the occurrence of a reach effect, and other multiple types of variable patterns. In addition, in relation to ensuring the performance time of the reach effect and the pseudo-consecutive effect, usually, the variable patterns that specify the reach effect and the pseudo-consecutive effect are defined to have a longer variable time than the normal variable pattern.

[0092] Based on the information included in the effect control commands (here, the variable pattern specification command and the decorative symbol specification command) sent from the main control board 40, the effect control board 41 determines the effect content (effect scenario such as a pre-announcement effect) to be developed in time series during the decorative symbol variable display game and the decorative symbol (decorative stop symbol) to be finally stopped and displayed, and variably displays the decorative symbol according to the time schedule based on the variable pattern of the special symbol to execute the decorative symbol variable display game. Thereby, in synchronization with the variable display of the special symbol by the special symbol display devices 22a and 22b, the decorative symbol is variably displayed by the liquid crystal display device 20, and the period of the special symbol variable display game and the period during the decorative symbol variable display game have substantially the same time width. Further, the effect control board 41 controls the liquid crystal display device 20, the light display device 16a, or the sound generation device 17a respectively so as to correspond to the effect scenario, and develops various effects in the decorative symbol variable display game. Thereby, the reproduction of the image (image effect) on the liquid crystal display device 20, the reproduction of the sound effect (sound effect), and the lighting and blinking drive of the decorative lamp 16, the LED, etc. (light effect) are realized.

[0093] In this way, the special symbol variation display game and the decorative symbol variation display game have an inseparable relationship, and what reflects the display result of the special symbol variation display game is expressed in the decorative symbol variation display game. Therefore, these two symbol variation display games may be regarded as equivalent symbol games. In this specification, unless particularly necessary, the above two symbol variation display games may be simply referred to as the "symbol variation display game".

[0094] (Regarding the general symbol hold) In the gaming machine 1, when a game ball passes through the normal symbol gate 26, that is, when a detection signal from the normal symbol gate detection sensor 26a is input, a random number (random number for general symbol determination) related to the normal symbol variation display game is acquired. This random number is used as hold data and is held and stored in the general symbol hold memory area of the RAM 40c up to the maximum hold memory number which is a predetermined upper limit value (for example, a maximum of 4). In the general symbol hold memory area, a hold 1 memory area to a hold n memory area (n is the maximum hold memory number: in this embodiment, n = 4) are provided, and each can store hold data for the maximum hold memory number. Note that the maximum hold memory number of the general symbol hold memory area is not particularly limited. The game ball related to the hold data stored in this general symbol hold memory area is also referred to as the "general symbol hold ball". In order to clarify the number of these general symbol hold balls to the player, the dot display corresponding to the number of general symbol hold balls in the composite display device 22c is lit, or the hold display provided as an icon image on the screen by the liquid crystal display device 20 is lit.

[0095] (Normal symbol variation display game) In the gaming machine 1, based on the fact that a game ball has passed through the normal symbol gate 26, a "normal symbol winning lottery" by random number lottery is conducted on the main control board 40. Based on the result of this lottery, a normal symbol represented by an LED is variably displayed on the composite display device 22d to start a normal symbol variable display game. After a predetermined variable time has elapsed, the result is stopped and displayed in a combination of lighting and non-lighting of the LEDs. For example, when the result of the normal symbol winning lottery is "normal symbol win", depending on the normal symbol win type, a specific LED of the composite display device 22d is stopped and displayed in a specific lighting state (for example, all 2 LEDs are in the lit state, or the "○" side LED among the LEDs representing "○" and "×" is in the lit state). Note that in this embodiment, only one type of normal symbol win type is provided.

[0096] When this "normal symbol win" occurs, the normal electric accessory solenoid 25a (see Fig. 5) operates, the second start port 24 is opened or enlarged, and a state is created in which it is easy for game balls to flow in (start port open state). A gaming state more advantageous to the player (hereinafter referred to as "normal electric open gaming") occurs than when the second start port 24 is closed. In this normal electric open gaming, the opening time of the second start port 24 by the normal electric accessory 25 elapses for a predetermined time (for example, 5.7 s), or until the number of game balls winning in the second start port 24 reaches a predetermined number (for example, 10), the winning area is opened or enlarged, and when any of these conditions are met, the second start port 24 is closed, and such an operation is repeated a predetermined number of times (for example, at most 1 time).

[0097] [Regarding 3.3 Jackpot] Next, the "jackpot" in the gaming machine 1 will be described. In the gaming machine 1, "4R1", "10R", and "4R2" are provided as jackpot types. When the result of the jackpot lottery is "jackpot", a lottery for the jackpot type is conducted in the symbol lottery. Note that the above notation of "R" means the specified number of rounds (maximum number of rounds).

[0098] The jackpot type is the winning that triggers the operation of the conditional device. Here, the "conditional device" refers to a device whose operation is required as a condition for the operation of the continuous operation device of the accessory for playing the round game. It operates when a specific combination of special symbols is displayed or when the game ball passes through a specific area within the big winning opening.

[0099] When a jackpot game is executed, the game state after the end of the jackpot game, the number of high-probability times, and the number of time-shortening times are determined according to the game state at the time of jackpot winning and the determined jackpot type. The number of high-probability times is set when the game state after the jackpot game is a high-probability state. In the gaming machine 1, the high-probability state after the jackpot game continues until the execution times of the special symbol variation display game reach the number of high-probability times (for example, 154 times). When the special symbol variation display game with the number of high-probability times ends without winning the jackpot in the jackpot lottery, the game state is set (shifted) to the low-probability state. The number of time-shortening times is set when the game state after the jackpot game is a time-shortening state. In the gaming machine 1, the time-shortening state after the jackpot game continues until the execution times of the special symbol variation display game reach the number of time-shortening times (for example, 150 times). When the special symbol variation display game with the number of time-shortening times ends without winning the jackpot in the jackpot lottery, the game state is set (shifted) to the non-time-shortening state. However, the gaming machine 1 may be of the "general high-probability type" in which the number of high-probability times and the number of time-shortening times continue until winning the jackpot in the jackpot lottery (until the next time). Note that the number of time-shortening times may be the total execution times of the special symbol variation display game 1 and the special symbol variation display game 2 (the total variation times of the special figure 1 and the special figure 2), or may be the execution times of either one (for example, the execution times of the special symbol variation display game 2).

[0100] Here, in this embodiment, similar to the jackpot type, a plurality of non-winning types are provided for "non-winning". Specifically, three non-winning types of "non-winning 1", "non-winning 2", and "non-winning 3" are provided. As described above, when the result of the jackpot lottery is "non-winning", the non-winning type lottery is conducted in the symbol lottery.

[0101] [Regarding 3.4 Performances] (Performance mode) Next, the performance mode (performance state) will be described. The gaming machine 1 of the present embodiment is provided with a plurality of types of performance modes for presenting performances related to the gaming state, and is configured to be able to move back and forth between those performance modes. Specifically, a performance mode corresponding to the set gaming state is provided. In each performance mode, the background display as the background of the variable display screen of the decorative symbol is displayed by different background performances, so that the player can grasp what kind of gaming state they are currently staying in.

[0102] The performance control board 41 (CPU 41a) has a functional unit (performance state transition control means) for performing transition control between a plurality of types of performance modes. The performance control board 41 (CPU 41a) is based on a specific performance control command sent from the main control board 40 (CPU 40a), specifically, a performance control command including the gaming state information managed on the main control board 40 side. In a form that maintains consistency with the gaming state managed on the main control board 40 side, it grasps the current gaming state and is configured to be able to perform transition control between a plurality of types of performance modes. Examples of the above specific performance control commands include a variable pattern designation command, a decorative symbol designation command, a gaming state designation command sent when a change occurs in the gaming state, and the like.

[0103] (Preview performance) Next, the preview performance will be described. The performance control board 41 is configured to be able to control the appearance of various "preview performances" related to the current performance mode and the jackpot lottery result based on the content of the performance control command from the main control board 40, specifically, at least the variation pattern information included in the variation pattern designation command. Such a preview performance serves as a "stimulating performance" that suggests (previews) the degree of expectation (hereinafter referred to as "winning expectation") of whether or not a winning type has been won, and stimulates the player's winning expectation. Typical preview performances include "reach performance", "pseudo consecutive performance", and further "advance notice preview performance", etc. The performance control board 41 functions as preview performance control means capable of controlling the execution (appearance) of these performances.

[0104] The "reach performance" refers to a performance mode accompanied by a reach state (a variation display mode accompanied by a reach state: a reach variation pattern), specifically, a performance mode that derives and displays the final game result via the reach state. The reach performance includes a plurality of types of reach performances associated with the winning expectation. For example, there are those in which the winning expectation relatively increases compared to when a normal reach performance appears. Such a reach performance is called a'super reach performance'. Many of these "super reaches" have a relatively longer performance time (variation time) than the normal reach in order to stimulate the winning expectation. Also, the normal reach and the super reach include a plurality of types of reach performances. The super reach includes a plurality of types of reach performances such as super reach 1, 2, 3, and 4, and the winning expectations of these super reaches 1 to 4 have a relationship of "super reach 1 < super reach 2 < super reach 3 < super reach 4".

[0105] "Pseudo-sequential presentation" refers to a presentation mode accompanied by a pseudo-continuous variation display state (pseudo-continuous variation) of a decorative pattern. "Pseudo-continuous variation" refers to a variation display mode in which, during a decorative pattern variation display game, part or all of the decorative pattern is temporarily stopped once, and the re-variation display operation of the decorative pattern is executed from the temporarily stopped state, and such display operations are repeated one or more times. In this regard, it is different from the "forecast presentation (sequential forecast presentation)" described later, which is developed across multiple symbol variation display games. Such "pseudo-sequential" basically has its occurrence rate (appearance rate) determined so that the winning expectancy increases as the number of pseudo-variations increases. For example, according to the number of pseudo-variations, presentations for enhancing the expectancy such as super reach are likely to be selected.

[0106] "Forecast presentation" (hereinafter sometimes abbreviated as "forecast" or "forecast presentation") means a presentation that notifies the possibility of being controlled to an advantageous state before the variation display of the symbol to be judged is performed based on the result of the forecast judgment. Note that the "advantageous state" means a state advantageous to the player. Specifically, the forecast presentation is mainly performed in a presentation mode that can notify the winning expectancy in advance before the held ball (undigested held ball), which has not yet been used in the execution of the symbol variation display game (variation display operation of special symbols), is used in the symbol variation display game, by using the held display mode and the background presentation of the symbol variation display game executed previously. In the symbol variation display game, in addition to the above "reach presentation", various presentations such as so-called "SU (step-up) forecast presentation", "timer forecast presentation", "revival presentation", "premium forecast presentation", etc. occur to enliven the game content.

[0107] Here, referring to FIG. 6, the "held change forecast presentation" as an example of the above forecast presentation will be described. In the case of the gaming machine 1 of this embodiment, in the upper display area within the screen of the liquid crystal display device 20, there is provided a display area (a display area for presenting a variable display effect and a preview effect of a decorative symbol) that presents a decorative symbol variable display game. Also, in the lower display area within the screen, there are provided a hold display area 60 (hold display parts a1 to d1) that displays the number of hold balls on the special symbol 1 side and a hold display area 61 (hold display parts a2 to d2) that displays the number of hold balls on the special symbol 2 side. Regarding the presence or absence of hold balls, that fact is notified by a predetermined hold display mode. FIG. 6 shows an example in which information regarding the current number of hold balls is notified in a lit state (there is a hold ball: the illustrated "○ (white circle mark)") or an unlit state (there is no hold ball: the illustrated broken-line circle mark).

[0108] The display (hold display) regarding the presence or absence of hold balls is sequentially displayed in the order of their occurrence (winning order). In each of the hold display areas 60 and 61, the leftmost hold ball is displayed as the hold ball that occurred first (that is, the oldest) on the time axis among all the hold balls within the hold display. Also, on the left side of the hold display areas 60 and 61, there is provided a variable display area 62 for indicating the hold balls that are currently being used in the special symbol variable display game. In the case of this embodiment, the variable display area 62 is configured such that an image in which the icon of the in-game hold K currently being used in the game appears on the icon of the receiving seat J appears. That is, when the variable display of the special symbol 1 or the special symbol 2 is started, the icon (icon image) of the oldest hold a1 or a2 displayed in the hold display areas 60 and 61 moves as the icon of the in-game hold K onto the icon of the receiving seat J in the variable display area 62, and that state is maintained for a predetermined display time.

[0109] When a hold ball occurs, a "hold addition command" that designates the prediction determination information related to the jackpot lottery result and the number of hold balls at the time of prediction determination (including the hold ball that occurred this time and the existing number of hold balls) is transmitted from the main control board 40 to the effect control board 41 (see FIG. 14). In the case of this embodiment, the hold addition command is composed of 2 bytes, and the hold addition command is composed of the upper byte data that can specify the number of held balls at the time of pre-reading determination and the lower byte data that can specify the pre-reading determination information.

[0110] Here, as understood from the above description, in this embodiment, based on the fact that a game ball has entered the first start port 23 or the second start port 24 and a new held ball has been generated, a jackpot lottery for the symbol variation display game related to the held ball is performed as a pre-reading determination. As will be described later, the main control board 40 holds and stores information representing the result of the jackpot lottery performed as such a pre-reading determination in the corresponding storage area of the RAM 40c. The information on the jackpot lottery result obtained at the time of pre-reading determination is used to select (lottery) the symbol variation pattern in the symbol variation display game, and can be paraphrased as "information for selecting the variation pattern" so to speak. Therefore, it can be said that the main control board 40 performs a pre-reading determination and holds and stores the "information for selecting the variation pattern" obtained as a result thereof in a predetermined area of the RAM 40c.

[0111] When the effect control board 41 receives the above-described hold addition command transmitted by the main control board 40, based on the pre-reading determination information included therein, as part of the display control process related to the above-described hold display, an effect control process related to the "pre-reading notice effect" is performed. Specifically, a "pre-reading notice lottery" for lottery whether to execute the pre-reading notice effect is performed, and when winning this lottery, the pre-reading notice effect is presented.

[0112] Here, the pre-reading determination information is, specifically, gaming information obtained by pre-reading the jackpot lottery result (the jackpot lottery result at the start of variation) or the variation pattern at the start of variation that is executed when the held balls are used in the symbol variation display game on the main control board 40. That is, this information includes at least the information obtained by pre-reading the jackpot lottery result at the start of variation (pre-reading win / loss information), and in addition, information obtained by pre-reading the symbol lottery result (pre-reading symbol information) and information obtained by pre-reading the variation pattern at the start of variation (pre-reading variation pattern information) can be included. Regarding what information to include in the hold addition command sent to the effect control board 41, it can be appropriately determined according to the content notified by the pre-reading notice. It is assumed that the hold addition command includes pre-reading win / loss information, pre-reading symbol information, and pre-reading variation pattern information.

[0113] Note that the "pre-reading variation pattern" obtained by pre-reading determination at the time of occurrence of held balls does not necessarily have to be the "variation pattern at the start of variation" itself obtained when the held balls are actually used in the variation display operation. For example, taking as a representative case where the variation pattern at the start of variation designates "Super Reach 1", in this case, it can be specified that the content designated by the pre-reading variation pattern is not the type of reach effect itself of "Super Reach 1", but the essence thereof, the "Super Reach type".

[0114] In the case of this embodiment, when winning the pre-reading notice lottery, among the hold icons of the hold display parts a1~d1, a2~d2, the hold icon that is the target of the pre-reading notice can change, for example, from the white color of the normal hold display (normal hold display mode) to the hold display (special hold display mode) by the blue, green, red, danger pattern (or special colors or patterns such as rainbow colors) of the notice display. A pre-reading notice effect of the "hold display change system" (also referred to as "hold change notice") is performed. FIG. 6 shows an example in which the held ball in the hatched held display section b1 changes to a special held display. Here, the display of the held icons in blue, green, red, and the danger pattern indicates, in this order, a high probability of winning. In particular, the display of the held icon with the danger pattern is a premium held icon that indicates an extremely high probability of a jackpot win.

[0115] (Presentation means) Various presentations in the gaming machine 1 are presented by presentation means provided in the gaming machine 1. This presentation means may be any means of transmitting stimuli that can exert a presentation effect by appealing to human perception such as vision, hearing, and touch. Examples thereof include light generation means such as a decorative lamp 16 and an LED device (light display device 16a: light presentation means), an acoustic generation device such as a speaker 17 (acoustic generation device 17a: sound presentation means), a presentation display device such as a liquid crystal display device 20 (display means), a pressurizing device that transmits a contact pressure to the operator's body, a wind pressure device that applies a wind pressure to the player's body, and a movable object accessory 50 that exerts a visual presentation effect by its operation. Here, the presentation display device is a display device that appeals to vision like the image display device, but is different from the image display device in that it includes those that do not depend on images (for example, a 7-segment display). When referring to an image display device, it mainly refers to a type that presents a presentation by image display. Those that present a presentation by means other than an image, such as a 7-segment display, are included in the concept of the above presentation display device.

[0116] <4. Processing of the main control board> Next, the processing performed by the main control board 40 of the present embodiment will be described. The processing of the main control board 40 mainly includes a main process (main control side main process: FIG. 7) and a timer interrupt process (main control side timer interrupt process: FIG. 9) that is started by a periodic interrupt from the CTC.

[0117] [4.1 Main control side main process] FIG. 7 is a flowchart showing the main control side main process. The main control side main process starts when a system reset occurs due to a system reset signal from the power supply board 200 during recovery from a power outage or power supply abnormality, or when the watchdog timer (WDT) is activated due to a runaway control program and the CPU 40a is forcibly reset (WDT reset). In any case, when the main control side main process starts, at step S101, the CPU 40a executes initial setting processing necessary for starting a game operation, such as initializing the values of the registers of each part including the CPU 40a.

[0118] When the initial setting processing in step S101 is completed, the CPU 40a determines in step S102 whether the backup flag is in the ON state (backup flag = 5AH is in the ON state). In the gaming machine 1, at the time of power-off, processing for backing up the stored information in the RAM 40c is performed by a power check / backup process (step S201, see FIG. 9) in the main control side timer interrupt process described later. When the backup process is properly performed at the time of power-off, the backup flag is set to the ON state. Therefore, in step S102, the backup flag is checked to determine whether backup restoration is possible.

[0119] If it is determined in step S102 that the backup flag is not ON, the CPU 40a proceeds to step S103, performs corresponding processing when the backup flag is OFF, and advances the processing to step S108. Note that in step S103, predetermined processing (for example, processing for storing necessary information in the RAM 40c) is performed as processing when the backup flag was OFF.

[0120] On the other hand, if it is determined in step S102 that the backup flag is ON, the CPU 40a determines in step S104 whether the RAM clear condition (the condition for shifting to the RAM clear process) is satisfied. Specifically, it is determined whether the RAM clear switch 34 is in the ON state. When it is determined that the RAM clear condition is satisfied, the CPU 40a executes the RAM clear process in step S105 and proceeds to step S108. The RAM clear process in step S105 is a process of initializing values within a predetermined area (used area) including the work area in the RAM 40c.

[0121] In step S104, when it is determined that the RAM clear condition is not satisfied, the CPU 40a proceeds to step S106 and performs a process of transmitting a predetermined effect control command corresponding to the backup restoration to the effect control board 41 as the command transmission process at the time of backup restoration.

[0122] In step S107 following step S106, the CPU 40a performs a backup restoration process. The backup restoration process is a process of restoring the operation before power-off after power-on based on the stored content of the RAM 40c backed up at the time of power-off. Specifically, the CPU 40a restores the stack pointer before power-off and performs a process for starting the game operation from the processing state at the time of power-off. Also, in the backup restoration process, in order for a power failure restoration display command (OB03H) for performing an information display instruction corresponding to the case of backup restoration to be transmitted to the effect control board 41 in the pre-processing of the main loop in step S110 described later, a process of storing the lower byte data of the power failure restoration display command in a register is executed.

[0123] In response to executing the backup restoration process in step S107, the CPU 40a proceeds to step S108. As described above, when the process of the previous step 103 is performed or when the process of step S105 is performed, the CPU 40a also proceeds to step S108.

[0124] In step S108, the CPU 40a performs setting of the CTC for periodically generating a timer interrupt at predetermined intervals such as every 4 ms. By performing the setting process of this step S108, thereafter, an interrupt request signal is periodically output to the interrupt controller, and the main control side timer interrupt process is executed.

[0125] In step S109 following step S108, the CPU 40a performs a process of transmitting an effect control command for instructing the start of the game to the effect control board 41, and then proceeds to step S110 to execute pre-processing before the main loop. In the pre-processing before the main loop, commands for instructing the initialization (home position return) of the movable accessory 50, transmission processes of commands indicating the number of held balls in special figure 1 and special figure 2, setting processes of internal function registers, a process of setting the performance display monitor lighting timer to 5 s, a process of turning on the emission permission signal for the payout control board 42, etc. are executed. Then, in step S111, the CPU 40a executes the main loop process.

[0126] (Main loop process) FIG. 8 is a flowchart showing the main loop process of step S111. In the main loop process of FIG. 8, the CPU 40a sets the interrupt prohibited state in step S121, and executes a random number update process in the subsequent step S122. In this random number update process, various random numbers used in the special symbol variation display game and the normal symbol variation display game (random numbers related to the jackpot lottery that circulate within a predetermined numerical range by increment processing (special symbol determination random numbers), random numbers related to the normal symbol lottery (normal symbol lottery determination random numbers), random numbers for changing the initial values (start values) (special symbol determination initial value random numbers, normal symbol lottery determination initial value random numbers), and random numbers for pattern variation used for selecting the variation pattern) are updated.

[0127] In the RAM 40c of this embodiment, as various random number counters used for symbol lottery related to jackpot lottery, general symbol winning lottery, variable pattern lottery, etc., there are provided a counter for generating the initial value of the special symbol determination random number counter, a special symbol determination random number counter, a counter for generating the initial value of the general symbol winning determination random number counter, a general symbol winning determination random number counter, a random number counter for variable pattern, etc. These counters serve as means for generating random numbers software-wise. In the random number update process of step S122, two initial value generation counters for generating the initial values of the above-mentioned special symbol determination random number counter and general symbol winning determination random number counter, the random number counter for variable pattern, etc. are updated to generate the above various software random numbers. For example, if the numerical range that can be taken as the random number counter for variable pattern is "0 to 9999", a value is obtained from the count value storage area for generating the value of the random number for variable pattern in the RAM 40c, "1" is added to the obtained value, and then it is stored in the original count value storage area. At this time, if the result of adding "1" to the obtained value is "10000", "0" is stored in the original random number counter storage area. The other initial value generation random number counters are updated in the same way.

[0128] After finishing the random number update process of step S122, the CPU 40a performs the process of saving the values of all registers in step S123, and then performs the performance display monitor aggregation division process in step S124. This performance display monitor aggregation division process is a process of calculating the value as the above-mentioned performance information (here, for example, taken as the value as "normal time ratio information"). The value of the normal time ratio information is calculated using the total number of payouts and the total number of out balls. However, the CPU 40a calculates the total number of payouts based on the result of counting the number of game balls that won in the winning ports (the first start port 23, the second start port 24, the general winning port 31, the first big winning port 27, the second big winning port 28), and obtains the total number of out balls by counting the number of game balls discharged from the game area 19. The counting of winning balls and the counting of out balls are performed in the input management process (refer to step S204 in FIG. 9) described later in the main control side timer interrupt process. Based on the count values obtained by respectively counting the number of winning balls and the number of out balls in the timer interrupt process side in this way, the CPU 40a calculates a value as normal time ratio information in step S124. As described above, the calculated value as normal time ratio information is stored in a predetermined area (measurement information storage area) of the RAM 40c. Note that the value of the normal time ratio information calculated in this way is displayed on the performance display 35 by the performance display monitor display process (refer to step S214 in FIG. 9) described later in the main control side timer interrupt process.

[0129] In step S125, the CPU 40a performs a full register return process, and then in the subsequent step S126, after setting to the interrupt enabled state, it returns to step S121.

[0130] In this way, in the main loop process of step S111, the processes of steps S121 to S126 are repeatedly executed in an infinite loop. The CPU 40a repeatedly executes the processes of steps S121 to S126 except during the timer interrupt process that is intermittently executed.

[0131] [4.2 Main Control Side Timer Interrupt Process] Referring to the flowchart of FIG. 9, the main control side timer interrupt process will be described. The main control side timer interrupt process is activated by an interrupt every fixed time (about 4 ms) from the CTC, and is executed by interrupting during the execution of the main control side main process.

[0132] As shown in FIG. 9, when a timer interrupt occurs, the CPU 40a executes the power check and backup process of step S201. In this power check and backup process, mainly, the power level supplied from the power supply board is monitored, and when an abnormality such as a power failure occurs, backup processing such as storing predetermined game information at the time of power failure in the RAM 40c is performed so that the game can resume smoothly when the power is restored.

[0133] After finishing the power check and backup process of step S201, the CPU 40a executes the input data creation process in step S202. Specifically, input data is created based on input information (ON / OFF signals, rising states (ON edges, OFF edges)) output from various sensors and switches. The input information here is, for example, ON / OFF information (winning detection information) of detection signals output from detection sensors such as the first start port detection sensor 23a, the second start port detection sensor 24a, the normal symbol gate detection sensor 26a, the first big winning port detection sensor 27a, the second big winning port detection sensor 28a, the general winning port detection sensor 31a, the OUT monitoring sensor 32a, etc., ON / OFF information (operation information) of switch signals output from various switches such as the RAM clear switch 34, status signals from the payout control board 42 (ON / OFF information of the front door open sensor 48 and the full cup detection sensor 47), radio wave sensors, magnetic sensors, etc. Thus, whether a game ball is detected at the out port or each winning port is monitored for each interrupt.

[0134] After finishing the input data creation process of step S202, the CPU 40a executes a timer management process in step S203 to manage the timers used for game operation control. Here, updates (subtraction processes) are performed on the values of various timers used for game operation control of the gaming machine 1.

[0135] Next, in step S204, the CPU 40a performs input management processing. In this input management processing, based on the input data created in the input data creation processing (S202), values such as the values of the winning counter and the OUT ball monitoring counter are updated. The "winning counter" is a counter provided corresponding to each winning opening and counts the number of winning game balls (winning balls). The OUT ball monitoring counter is a counter that counts the game balls (OUT balls) discharged from the game area 19.

[0136] In step S205, the CPU 40a executes error management processing. In this error management processing, based on the input data related to various sensors and the status signals from the payout control board 42, the presence or absence of an error occurrence is monitored. When an error occurs, if it is an error type that requires the transmission of an error command as error processing, the CPU 40a transmits the corresponding command to the effect control board 41. When the effect control board 41 receives this error command, it executes an error notification corresponding to the error type. Also, when the error in progress is resolved, the CPU 40a transmits an error release command to the effect control board 41. When the effect control board 41 receives this error release command, it terminates the error notification in progress.

[0137] Next, in step S206, the CPU 40a executes timer interrupt internal random number management processing for periodically updating the random numbers related to each variable display game. Here, in order to make the count value of the random number counter random, for the special symbol determination random number, the normal pattern hit determination random number, etc., the random number is updated (+1 addition for each interrupt), and every time the random number counter makes a full circle, the start value of the random number counter is changed. Note that the big win determination random number is generated by the random number generation circuit and is not updated here.

[0138] In step S207, the CPU 40a executes prize ball management processing. In this prize ball management processing, the above-mentioned winning counter is checked, and when there is a winning, a payout control command specifying the number of prize balls is transmitted to the payout control board 42. When the payout control board 42 receives the payout control command, it controls the game ball payout device 46 based on the number of prize balls information included therein, and executes a payout operation for the specified number of prize balls.

[0139] Next, in step S300, the CPU 40a executes normal symbol management processing. In this normal symbol management processing, processing necessary for executing a normal symbol variation display game is performed. Note that the details of the normal symbol management processing in step S300 will be described later.

[0140] Furthermore, in step S208, the CPU 40a executes normal electric accessory management processing. In this normal electric accessory management processing, processing related to the operation control of normal electric accessories necessary for executing a normal electric accessory release game is performed.

[0141] Next, in step S400, the CPU 40a executes special symbol management processing. In this special symbol management processing, mainly, a jackpot lottery in a special symbol variation display game is performed, and based on the lottery result, processing necessary for executing a special symbol variation display game, such as determination of the variation pattern (preview variation pattern and variation pattern at the start of variation) of the special symbol, is performed. Note that the details of the special symbol management processing in step S400 will be described later.

[0142] Next, in step S209, the CPU 40a executes special electric accessory management processing. In this special electric accessory management processing, processing related to the operation control of special electric accessories necessary for executing a jackpot game is performed.

[0143] After finishing the processing for the game progress up to the above step S209, the CPU 40a performs external terminal management processing in step S210. In this external terminal management processing, the operation state information of the gaming machine 1 is output to external devices such as the hall computer HC and the island lamp through the external centralized terminal board 43 for the frame. The operation state information includes, for example, game information such as jackpot game occurrence information, start information of the symbol variation display game, winning number and prize ball number information, and error information.

[0144] Next, in step S211, the CPU 40a executes LED management processing. In this LED management processing, output processing of control signals (dynamic lighting data) for LED displays such as the special symbol display devices 22a and 22b and the composite display devices 22c and 22d is performed. The control signals based on the display data created in the normal symbol management processing (step S300), the special symbol management processing (step S400), etc. are output to the corresponding display devices or displays in this LED management processing, and display control is performed. Thereby, a series of variation display operations (variation display and stop display) of the special symbols in the special symbol display devices 22a and 22b and the normal symbols in the composite display device 22d are realized.

[0145] In step S212 following step S211, the CPU 40a executes solenoid management processing. Here, processing for outputting control signals (control data) to predetermined solenoids provided in the gaming machine 1, such as the normal electric accessory solenoid 25a for operating the above-described normal electric accessory 25, the first special electric accessory solenoid 29a for operating the first special electric accessory 29 that opens and closes the first big winning opening 27, and the second special electric accessory solenoid 30a for operating the second special electric accessory 30 that opens and closes the second big winning opening 28, is performed.

[0146] In step S213 following step S212, the CPU 40a performs the performance display monitor display processing of step S214 after saving the values of all registers. That is, it is processing for causing the performance display 35 to display the value as the above-described normal time ratio information. Then, the value of the normal ratio information is recalculated every time the total number of out balls in all states reaches a predetermined specified value, and the performance indicator 35 can display the current normal ratio information and the previous normal ratio information (the normal ratio information that was calculated and finalized at the most recent recalculation timing). Therefore, in the display process of step S214 in this case, a process of causing the performance indicator 35 to display the values as these two types of normal ratio information is performed. Note that the value of the current normal ratio information is the value calculated in the process of step S124 in the above-described main loop process (FIG. 8), and the value of the previous normal ratio information is stored in a predetermined area of the RAM 40c, and the CPU 40a reads out the stored value and causes the performance indicator 35 to display it.

[0147] In step S215 following step S214, the CPU 40a restores the values of all registers, in step S216 clears the count value of the WDT, and ends the main control side timer interrupt process.

[0148] When the above timer interrupt process ends, the CPU 40a executes the main loop process (S111) until the next timer interrupt occurs.

[0149] (Normal symbol management process) FIG. 10 is a flowchart showing the normal symbol management process. As shown in FIG. 10, in step S301, the CPU 40a determines whether or not it has detected the passage of a game ball through the normal symbol gate 26 based on the detection signal from the normal symbol gate detection sensor 26a.

[0150] If it is determined that the passage of a game ball through the normal symbol gate 26 has been detected, in step S302, the CPU 40a determines whether or not the number of normal symbol held balls is 4 or more. That is, it determines whether or not the number of normal symbol held balls is equal to or more than the maximum holding storage number (here, the upper limit is 4). However, if it is not detected that a game ball has passed through the normal symbol gate 26 (step S301: N), and if it is determined that the number of normal symbol held balls is 4, steps S302 to S304 are skipped and the process proceeds to step S305.

[0151] On the other hand, when it is determined that the number of general pattern reserved balls is less than 4 (less than 4), the CPU 40a adds 1 to the number of general pattern reserved balls in step S303, and stores the random number for general pattern determination related to the general pattern reserved balls generated this time in the general pattern reserved storage area of the RAM 40c in step S304.

[0152] In step S305, the CPU 40a determines the state of the general pattern hit flag. This "general pattern hit flag" is a flag for specifying whether it is during a general power release game. When the flag is in the ON state (for example, 5AH), it indicates that it is during a general power release game, and when the flag is in the OFF state (for example, 00H), it indicates that it is not during a general power release game.

[0153] When the general pattern hit flag is in the OFF state (≠5AH), that is, when it is not during a general power release game, in step S306, the CPU 40a executes a general pattern operation status determination process for branching the process related to the variable display operation of the general pattern according to the general pattern operation status (00H to 02H).

[0154] In the general pattern operation status determination process of step S306, corresponding processes are executed according to whether the general pattern operation status is any of "at the start of variation (00H)", "during variation (01H)", and "during confirmation time (02H)". The "general pattern operation status" is a value indicating the behavior of the general pattern, and the value is changed according to the processing state and stored in the general pattern operation status storage area of the RAM 40c.

[0155] Specifically, when the general pattern operation status is "at the start of variation (00H)", the CPU 40a determines in step S307 whether the number of general pattern reserved balls is zero. If it is determined that the number of general pattern reserved balls is zero, the processes of steps S308 to S313 are skipped, and the process proceeds to step S320.

[0156] On the other hand, when it is determined that the number of general pattern hold balls is not zero, in step S308, the CPU 40a subtracts 1 from the number of general pattern hold balls, and refers to the general pattern per determination table shown in FIG. 11, and performs a general pattern per lottery based on the earliest stored general pattern per determination random number (hold data) among the general pattern per determination random numbers stored in the general pattern hold storage area.

[0157] FIG. 11 is a diagram for explaining an example of a general pattern per determination table. Here, in a predetermined area of the ROM 40b, a general pattern per determination table as shown in FIG. 11 is stored. In the general pattern per determination table, a determination reference value TH between a low probability state and a high probability state is shown. In the general pattern per lottery in the present embodiment, the determination reference value TH is determined within the range (0 to 250) of values that the general pattern per determination random number can take, and a determination of a win or a miss for the general pattern per is made based on the result of comparing the magnitude relationship between the general pattern per determination random number and the determination reference value TH. As an example, a method is adopted in which a win determination result for the general pattern per is obtained when the value of the general pattern per determination random number is within the range of "0 to the determination reference value TH", and a miss determination result is obtained in other cases. In the example shown in FIG. 11, the determination reference value TH is set to 250 for both the low probability state and the high probability state. Therefore, in the present embodiment, in any case of the low probability state and the high probability state, a win for the general pattern per is always obtained in the general pattern per lottery.

[0158] FIG. 12 is a diagram for explaining an example of a winning type, a variation time, and a determination time related to a normal symbol variation display game. In step S310, as shown in FIG. 12, the CPU 40a performs a stop symbol creation process of determining a winning type based on the lottery result of the general pattern per lottery and the set game state, and creating a stop symbol corresponding to the determined winning type. Here, as described above, in any case of the low probability state and the high probability state, a win for the general pattern per is always obtained in the general pattern per lottery. When a win for the general pattern per is obtained, as shown in FIG. 12, "win 1" is determined as the winning type, and a stop symbol corresponding to "win 1" is created.

[0159] In step S311, the CPU 40a stores the variation time based on the game state (see FIG. 12) in the normal symbol device timer. Here, 132 ms is stored in the low-probability state, and 128 ms is stored in the high-probability state.

[0160] In step S312, the CPU 40a shifts the hold data stored in the hold memory area of the RAM 40c for the normal symbols. Here, the hold data stored in the hold memory areas for the normal symbols n (n = 2, 3, 4) is stored in the hold memory areas for the normal symbols corresponding to 'n - 1' respectively.

[0161] In step S313, the CPU 40a makes various settings at the start of the variation and proceeds to step S320. Here, for example, the normal symbol operation status is set to "in variation (01H)", the hold memory area 4 is cleared to create a free area, and the normal symbol variation flag is set to the ON state.

[0162] When the normal symbol operation status is "in variation (01H)", in step S314, the CPU 40a determines whether the normal symbol device timer is zero. If it is determined that the normal symbol device timer is not zero, step S315 is skipped and the process proceeds to step S320.

[0163] On the other hand, if it is determined that the normal symbol device timer is zero, in step S315, the CPU 40a makes various settings at the end of the variation and proceeds to step S320. Here, for example, the normal symbol operation status is set to "during confirmation time (02H)", the confirmation time (500 ms) based on the game state as shown in FIG. 12 is stored in the normal symbol device timer, and the normal symbol variation flag is set to the OFF state.

[0164] When the normal symbol operation status is "during confirmation time (02H)", in step S316, the CPU 40a determines whether the normal symbol device timer is zero. If it is determined that the normal symbol device timer is not zero, steps S317 to S319 are skipped and the process proceeds to step S320.

[0165] On the other hand, when it is determined that the normal symbol device timer is zero, in step S317, the CPU 40a sets the normal symbol operation status to "at the start of variation (00H)". In step S318, the CPU 40a determines whether or not it has won in the normal symbol lottery in step S309 for each normal symbol. If it is determined that it has not won for each normal symbol, it skips step S319 and proceeds to step S320.

[0166] On the other hand, when it is determined that it has won for each normal symbol, in step S319, the CPU 40a performs various settings for each normal symbol and proceeds to step S320. Here, the normal symbol flag is set to the ON state (5AH).

[0167] In step S320, the CPU 40a updates the normal symbol display data and ends the normal symbol management process. In this normal symbol display data update process, it is determined whether or not the normal symbol is in the process of variation. If it is in the process of variation, the 7-segment display data for when the normal symbol is in the process of variation is created. If the normal symbol is not in the process of variation, the 7-segment display data for when the normal symbol is stopped and displayed is created. The normal symbol display data created here is output to the composite display device 22d by the LED management process (step S211) in FIG. 9.

[0168] (Special symbol management process) FIG. 13 is a flowchart showing the special symbol management process (step S400). As shown in FIG. 13, in step S401, the CPU 40a performs a special symbol 1 start port check process for special symbol 1 (the first start port 23), and in the subsequent step S402, performs a special symbol 2 start port check process for special symbol 2 (the second start port 24). The details of these start port check processes will be described later.

[0169] After finishing the start port check process in steps S401 and S402, in step S403, the CPU 40a determines the state of the conditional device operation flag. This "conditional device operation flag" is a flag for specifying whether it is a jackpot game. When the flag is in the ON state (for example, 5AH), it indicates that it is during a jackpot game, and when the flag is in the OFF state (for example, 00H), it indicates that it is not during a jackpot game. Note that the conditional device operation flag is set to the ON state during the special symbol confirmation process (step S407) when winning a jackpot in the jackpot lottery, and is set to the OFF state in the jackpot end process (step S650) described later.

[0170] When it is determined that the conditional device operation flag is in the OFF state (≠5AH), that is, when it is determined that it is not during a jackpot game, in step S404, the CPU 40a executes a special symbol operation status branch process that branches the process related to the variable display operation of the special symbol according to the special symbol operation status (00H to 03H).

[0171] In the special symbol operation status branch process of step S404, corresponding processes are executed according to whether the special symbol operation status is "waiting (00H, 01H)", "changing (02H)", or "confirming (03H)". Note that the "special symbol operation status" is a value indicating the behavior of the special symbol, and the value is changed according to the processing state and is stored in the special symbol operation status storage area of the RAM 40c.

[0172] Specifically, when the special symbol operation status is "waiting (00H, 01H)", the CPU 40a executes the special symbol variation start process (step S405), when it is "changing (02H)", it executes the special symbol variation process (step S406), and when it is "confirming (03H)", it executes the special symbol confirmation time process (step S407). Here, the above "waiting" means that the special symbol is in a waiting state for the next variation, the above "changing" means that the special symbol is in the process of variation (variable display), and the above "confirming" means that the variation of the special symbol has ended and it is in the stop (determined) display (during the special symbol confirmation time).

[0173] Through the processes of steps S405, S406, and S407 described above, a variable display operation that sets one set of the start and stop of the special symbol variation is realized. Details of the process of step S405 will be described later.

[0174] When any of the processes of steps S405 to S407 is completed, in step S408, the CPU 40a executes a special symbol display data update process and ends the special symbol management process. In this special symbol display data update process, it is determined whether the special symbol is in the process of variation. If it is in the process of variation, data for 7-segment display during the variation of the special symbol is created. If the special symbol is not in the process of variation, data for 7-segment display during the stop display of the special symbol is created. The display data of the special symbol created here is output to the special symbol display devices 22a and 22b by the LED management process (step S211) in FIG. 9.

[0175] Also, when it is determined in step S403 that it is during a big win game (=5AH), the CPU 40a directly performs the special symbol display data update process in step S408 without performing the processes related to the variable display operation of the special symbol in steps S405 to S407. That is, during a big win game, the variable display operation of the special symbol is not performed (the display state of the special symbol on the special symbol display device remains in the state determined and displayed after the big win).

[0176] (Special Drawing 1 Start Port Check Process) FIG. 14 is a flowchart showing the special drawing 1 start port check process (step S401). This special drawing 1 start port check process serves as a winning time process that is executed based on the establishment of a predetermined start condition. In the special drawing 1 start port check process, as pre-start processing (winning time process for special drawing 1) for executing the special symbol variable display game 1 of special drawing 1, a process of adding the number of held balls of special drawing 1 caused by the occurrence of winning at the first start port 23, a process of storing various random numbers (held storage process), a process of transmitting a held addition command, etc. are executed. Note that the special drawing 2 start port check process (step S402) also serves as a winning process executed based on the fulfillment of predetermined start conditions, just like the special drawing 1 start port check process. As pre-start processing (winning process for special drawing 2) for executing the special symbol variation display game 2 of special drawing 2, addition processing of the number of hold balls of special drawing 2 caused by the winning of the second start port 24, storage processing of various random numbers, transmission processing of hold addition commands, etc. are executed. Therefore, the special drawing 1 start port check process and the special drawing 2 start port check process have substantially the same processing content. Hereinafter, the special drawing 1 start port check process will be mainly described, and the details of the special drawing 2 start port check process will be omitted to avoid duplicate description.

[0177] As shown in FIG. 14, in step S401-1, the CPU 40a determines whether or not it has detected the winning of a game ball into the first start port 23 based on the detection signal from the first start port detection sensor 23a. When it is determined that the winning into the first start port 23 has been detected, in step S401-2, the CPU 40a determines whether or not the number of hold balls of special drawing 1 (hereinafter referred to as "special drawing 1 hold balls") is 4 or more. That is, it is determined whether or not the number of special drawing 1 hold balls is equal to or more than the maximum hold storage number (here, the upper limit is 4). However, when it is determined that there is no detection of winning at the first start port 23, the special drawing 1 start port check process ends.

[0178] When it is determined in step S401-2 that the number of special drawing 1 hold balls is 4 or more, that is, when the winning at the first start port 23 has been detected but it is determined that the number of special drawing 1 hold balls is 4 or more, the CPU 40a proceeds to step S401-11 described later. On the other hand, when it is determined that the number of special drawing 1 hold balls is not 4 or more (less than 4), in step S401-3, 1 is added to the number of special drawing 1 hold balls.

[0179] In step S401-4, the CPU 40a acquires various random numbers used for the special symbol variation display game 1 related to the special drawing 1 hold balls generated this time. Specifically, from various random number counters, a jackpot determination random number, a special symbol determination random number, and a variation pattern random number are acquired, and the acquired random numbers are stored in the special drawing hold storage area of the RAM 40c.

[0180] In step S401-5, the CPU 40a acquires pre-reading prohibition data (EVENT: "01H") that prohibits pre-reading determination as winning command data for creating a hold addition command (data corresponding to the lower byte side (EVENT) of the hold addition command). Next, in step S401-6, the CPU 40a determines whether or not the "Special Figure 1 pre-reading prohibition condition" is satisfied. The Special Figure 1 pre-reading prohibition condition is a condition that prohibits pre-reading determination for the Special Figure 1 hold balls.

[0181] If the Special Figure 1 pre-reading prohibition condition is satisfied, the CPU 40a proceeds to step S401-11 without executing the pre-reading determination process (step S401-9) related to pre-reading determination. In this case, the hold addition command having the pre-reading prohibition data (EVENT: "01H") designates pre-reading prohibition, and the pre-reading determination for the current Special Figure 1 hold balls is prohibited. As a result, the pre-reading preview effect is not executed either. In other words, it can be said that the pre-reading prohibition data designates that the pre-reading determination process (step S401-9) has not been executed.

[0182] Here, instead of performing pre-reading determination for Special Figure 1 and Special Figure 2 regardless of the game state, it is determined whether or not to prohibit pre-reading based on the current game state. The reason is as follows. In the time-limited state where right hitting is advantageous, winning at the second start port 24 frequently occurs. However, considering that in the non-time-limited state where left hitting is advantageous, winning at the second start port 24 hardly occurs and winning at the first start port 23 frequently occurs, instead of blindly performing pre-reading determination for Special Figure 1 and Special Figure 2 regardless of the game state, in the time-limited state, pre-reading determination for the Special Figure 1 side is prohibited and pre-reading determination for the Special Figure 2 side is permitted, and in the non-time-limited state, pre-reading determination for the Special Figure 2 side is prohibited and pre-reading determination for the Special Figure 1 side is permitted.

[0183] In step S401-6, when it is determined that the pre-reading prohibition condition is not satisfied, in step S401-7, the CPU 40a executes a pre-reading determination process. In this pre-reading determination process, the jackpot lottery result executed at the start of the variation is pre-read and determined. Therefore, a series of processes related to the 'pre-reading validity determination' for pre-reading and determining the jackpot lottery result, the 'pre-reading symbol determination' for pre-reading and determining the symbol lottery result, and the 'pre-reading variation pattern determination' for pre-reading and determining the variation pattern at the start of the variation are included.

[0184] Specifically, in step S401-7, the CPU 40a acquires the jackpot determination random number value stored in the RAM 40c (special drawing reservation storage area), and based on the jackpot determination random number value and the jackpot determination table (see FIG. 17), performs a jackpot lottery (pre-reading validity determination for determining at least the difference between jackpot and non-jackpot) for the current reserved balls, and obtains the result (referred to as the 'pre-reading validity result').

[0185] Here, in the present embodiment, the pre-reading validity result is not stored in the RAM 40c but remains taken in a predetermined general-purpose register built into the CPU 40a. This is because the pre-reading validity determination result is immediately used in the subsequent pre-reading symbol determination process, and this data is not required thereafter, so there is no need to store it in the RAM 40c.

[0186] Also, in step S401-7, as the above-described pre-reading symbol determination process, the CPU 40a performs a symbol lottery using a symbol table (see FIG. 20) corresponding to the pre-reading validity result (at least the difference between jackpot and non-jackpot) and the reservation type (the difference between special drawings 1 and 2). Specifically, the CPU 40a performs a symbol lottery for the current reserved balls based on the special symbol determination random number acquired in the previous step S401-4 and the symbol table, and obtains the result (referred to as the 'pre-reading symbol result').

[0187] The CPU 40a does not store the preliminary draw symbol result in the RAM 40c, but instead takes it into a predetermined general-purpose register built into the CPU 40a as in the case of the above-described preliminary draw correctness determination. This is because the preliminary draw symbol result is immediately used in the subsequent preliminary draw variation pattern determination and is not required thereafter, so there is no need to store it in the RAM 40c.

[0188] After finishing the above-described preliminary draw symbol determination, the CPU 40a executes a preliminary draw variation pattern determination. In this preliminary draw variation pattern determination, a lottery of the variation pattern is performed using the above-described preliminary draw symbol result (any one of "4R1", "10R", "4R2", "miss 1", "miss 2", "miss 3"), a variation pattern table for selecting a variation pattern corresponding to the preliminary draw symbol result, and the random number for variation pattern obtained in step S401-4, and the preliminary draw variation pattern is determined. That is, the variation pattern (the variation pattern at the start of variation) to be executed when the current hold ball is used for the variation display operation is preliminarily determined.

[0189] The above-described variation pattern table is also used in the lottery of the variation pattern performed in the special symbol variation start process (FIG. 13). A specific example of the above-described variation pattern table and the lottery process of the variation pattern using the table will be described again when explaining the process at the start of variation.

[0190] Note that the preliminary draw variation pattern determination result (winning command data (EVENT)) is immediately used in the hold addition command creation process of step S401-8 described below, and thereafter, this data is not required. Therefore, the CPU 40a finishes the process of step S401-7 while taking the result of the preliminary draw variation pattern determination into the register without storing it in the RAM 40c.

[0191] In step S401-8, the CPU 40a creates data on the lower byte side of the hold addition command according to the pre-reading determination result. Specifically, data representing the type of the pre-reading variation pattern is created as the winning command data (EVENT) on the lower byte side of the hold addition command. Regarding the data of EVENT, the "01H" set in step S401-5 will be updated to the value corresponding to the pre-reading variation pattern (the value obtained in the pre-reading variation pattern determination process) in this process.

[0192] In step S401-9, the CPU 40a creates data on the upper byte side of the hold addition command according to the number of hold balls. That is, data representing the current number of hold balls and the above-mentioned pre-reading symbol result (the type of special symbol) is created as the winning command data (MODE) on the upper byte side of the hold addition command. Regarding the data of MODE, it is set to be able to distinguish between hold 1 to hold 4 of special figure 1 and hold 1 to hold 4 of special figure 2.

[0193] In step S401-10, the CPU 40a performs the transmission process of the hold addition command. That is, a hold addition command including the winning command data created in step S401-8 and step S401-9 as EVENT and MODE respectively is created and transmitted to the effect control board 41.

[0194] Here, when it is a pre-reading prohibition condition (Yes in S401-6), the CPU 40a maintains the above-mentioned pre-reading prohibition data (lower byte = 01H) without updating it and transmits a hold addition command with the pre-reading prohibition data. Also, at the time of overflow (when a new winning occurs when the maximum number of hold memories has been reached), a hold addition command designated for overflow is transmitted (the Yes route of step S401-2).

[0195] Note that after the hold addition command is sent from the main control board 40 to the effect control board 41, it is only used when the effect control board 41 displays the "forecast preview effect" related to the current hold ball, and is not particularly used in the special symbol variation start process shown in FIG. 12. Therefore, the CPU 40a does not store the hold addition command in the RAM 40c either, and after exiting the special symbol 1 start port check process in step S401, it will subsequently perform the special symbol 2 start port check process in step S402.

[0196] (Special symbol variation start process) FIG. 15 is a flowchart showing the special symbol variation start process (step S405), which is the process at the start of variation. As shown in FIG. 15, in step S405-1, the CPU 40a determines whether the number of hold balls in special symbol 2 (special symbol 2 hold ball number) is zero. If the special symbol 2 hold ball number is not zero, it proceeds to step S405-6 and performs the process at the start of variation (steps S405-6 to S405-14) for the special symbol 2 hold balls to be used for the current variation display.

[0197] On the other hand, if it is determined in step S405-2 that the number of hold balls in special symbol 1 (special symbol 1 hold ball number) is zero, the CPU 40a determines whether the number of hold balls in special symbol 1 is zero. If it is determined that the special symbol 1 hold ball number is not zero, it proceeds to the process in step S405-6 and performs the process related to the start of variation of the special symbol for the special symbol 1 hold balls to be used for the current variation display (steps S405-6 to S405-14). By the processes of steps S405-1 and S405-2 above, the "priority variation order" of which of the special symbol 1 hold balls and the special symbol 2 hold balls is preferentially used for the variation display operation (which hold balls are preferentially consumed) is determined. In this embodiment, when there are hold balls in both the special symbol 1 hold balls and the special symbol 2 hold balls, the special symbol 2 hold balls are preferentially consumed. That is, the special symbol variation display game 2 is preferentially executed over the special symbol variation display game 1. Note that, not limited to the above priority variation type, a configuration may be adopted in which the hold balls are consumed in the order of winning.

[0198] In addition, when the number of hold balls for both the special figure 2 and the special figure 1 is zero, it becomes a state of "no hold balls". This state of "no hold balls" is a case where the special symbol is on standby and there is no hold memory. When entering this state, it is notified to the production control board 41 side, and the liquid crystal display device 20 is controlled to switch to the demo screen display for customer waiting (customer waiting demo screen). Therefore, when it becomes "no hold balls", it proceeds to step S405-3, and the CPU 40a determines whether the special symbol operation status indicates "standby (00H)" in the state of "no hold balls".

[0199] If it is determined in step S405-3 that the special symbol operation status is not "standby (00H)", that is, if it is determined that the special symbol operation status is "standby (01H)", then in step S405-4, the CPU 40a switches the special symbol operation status to "standby (00H)" (stores 00H in the special symbol operation status). Then, in step S405-5, the CPU 40a transmits a "demo display command" for displaying the customer waiting demo screen to the production control board 41 as a production control command, and ends the special symbol variation start process. Thereafter, when the determination process of step S405-3 is executed and it is "standby (00H)", the CPU 40a ends the special symbol variation start process without transmitting the demo display command again.

[0200] If it is determined in step S405-1 that the number of hold balls for the special figure 2 is not zero, and if it is determined in step S405-2 that the number of hold balls for the special figure 1 is not zero (when the number of hold balls for the special figure 2 is zero while the number of hold balls for the special figure 1 is not zero), the CPU 40a performs the processes related to the start of the variation of the special symbol for the hold balls to be used in the current variation display (steps S405-6 to S405-14). Here, regarding the processes of steps S405-6 to S405-14 described below, if the determination in step S405-1 above is 'No', it is a process for the special figure 2 held balls, and if the determination in step S405-2 above is 'No', it is a process for the special figure 1 held balls. However, since the ways of processing are the same, in order to avoid duplicate descriptions, unless particularly necessary, the description will be made without distinguishing whether it is a process for the special figure 1 held balls or a process for the special figure 2 held balls.

[0201] In step S405-6, the CPU 40a subtracts 1 from the number of held balls (the number of held balls related to the special symbol side for this variation display operation - 1), and then in the subsequent step S405-7, it transmits a "held ball subtraction command" including the information on the number of held balls after subtraction to the effect control board 41. By this held ball subtraction command, the effect control board 41 side grasps the remaining number of held balls after the consumption of the current number of held balls and shifts the current held display.

[0202] In step S405-8, the CPU 40a sets special symbol operation confirmation data. This special symbol operation confirmation data is information specifying the special symbol on the side where the variation starts this time. For example, if special symbol 1 is on the side where the variation starts, "00H (special figure 1 variation start designation)" is stored in a predetermined area (special symbol operation confirmation data storage area) of the RAM 40c, and if special symbol 2 is on the side where the variation starts, "01H (special figure 2 variation start designation)" is stored.

[0203] In step S405-9, the CPU 40a shifts the saved data stored in the special figure save memory area of the RAM 40c, and in the subsequent step S405-10, clears the save 4 memory area. In the processing of steps S405-9 to S405-10, the saved data (jackpot determination random number, special symbol determination random number, and variation pattern random number) stored in the save memory area corresponding to the save memory number n = 1 (save 1 memory area) is read out and stored in the determination random number storage area of the RAM 40c. At the same time, the saved data stored in the save memory areas corresponding to the save n memory areas (n = 2, 3, 4) (save 2 memory area, save 3 memory area, save 4 memory area) is stored in the save memory area corresponding to 'n - 1' respectively (step S405-9), and the save 4 memory area is cleared to provide a free area (step S405-10).

[0204] In step S405-11, the CPU 40a performs the process of transmitting the remaining variation count designation command and the game state command. Here, the CPU 40a determines whether the "short time count counter" that counts the short time count in the short time state is zero. If the short time count is not zero, it transmits the "remaining variation count designation command" including the short time count to the effect control board 41. With this "remaining variation count designation command", the effect control board 41 can execute the process of grasping and notifying the short time count. In addition, the CPU 40a also performs the process of transmitting a game state command that designates the current game state to the effect control board 41.

[0205] In step S411, the CPU 40a executes a jackpot random number determination process for performing a jackpot lottery. Note that the details of the jackpot random number determination process will be described later.

[0206] In step S412, the CPU 40a executes a symbol lottery process for performing a symbol lottery. Note that the details of the symbol lottery process will be described later.

[0207] In step S413, the CPU 40a executes a variation pattern lottery process for performing a variation pattern lottery. Details of the variation pattern selection process in this embodiment will be described later.

[0208] Here, as described above, the lottery results of the jackpot lottery and the symbol lottery at the start of the variation are stored in the RAM 40c. The reason for this is that these lottery results are not only used in the special symbol management process (step S400), but also data that will be used in subsequent special electric accessory management processes (step S209) and the like. In this regard, this is different from the process at the time of the look-ahead determination where the lottery result is not stored in the RAM 40c.

[0209] Although not shown in the drawings, when the jackpot lottery result is a jackpot, the CPU 40a performs necessary setting processing for designating the game state after the jackpot game as setting processing for shifting the game state following step S413 (game state transition preparation processing).

[0210] In step S405-12, the CPU 40a stores 5AH (ON state) in the special symbol N variation flag (N = 1, 2) that designates that the special symbol is in the variation display. The "special symbol N variation flag" is a flag indicating whether any of the special symbols 1 and 2 is in the variation. When the flag is in the ON state (= 5AH), it indicates that the target special symbol is in the variation, and when the flag is in the OFF state (= 00H), it indicates that the target special symbol is stopped. Note that the special symbol 1 variation flag (N = 1) corresponds to special symbol 1, and the special symbol 2 variation flag (N = 2) corresponds to special symbol 2.

[0211] In step S405-13, the CPU 40a executes the command transmission process at the start of the variation. In this command transmission process, in order to notify the effect control board 41 of the variation pattern selected in the variation pattern lottery in step S413, as an effect control command, a "variation pattern designation command" including variation pattern information that can identify the variation pattern is created and transmitted to the effect control board 41. In the command transmission process, based on the symbol lottery result in step S412, a decoration symbol designation command is created and transmitted to the effect control board 41. The decoration symbol designation command is composed of two bytes: the upper byte (MODE) that designates the hold type and the lower byte (EVENT) that designates the type of special symbol. Therefore, this decoration symbol designation command includes information regarding the hold type and the type of special symbol (symbol lottery result). Since this decoration symbol designation command includes information regarding the type of special symbol, it is mainly used in the effect control board 41 to determine the combination of decoration symbols when forming a reach state (symbol types that include the reach symbol as a component), the combination of the decoration symbols to be finally stopped and displayed (decoration stop symbols), and the preview effect corresponding to the winning type in the symbol variation display game, etc.

[0212] In step S405-14, the CPU 40a executes the variation start setting process and ends the special symbol variation start process. Here, the special symbol operation status is switched to "in variation (02H)" (store 02H in the special symbol operation status), and the process of clearing the determination random number storage area is performed.

[0213] (Big win random number determination process) FIG. 16 is a flowchart showing the big win random number determination process (step S411), FIG. 17 is a diagram showing an example of the big win determination table, and FIG. 18 is a diagram for explaining the big win random number determination method.

[0214] As shown in FIG. 16, in step S411-1, the CPU 40a selects a big win determination table according to the hold type (special figure 1, special figure 2). Here, in a predetermined area (address) of the ROM 40b, a big win determination table as shown in FIG. 16 is stored. The big win determination table is provided for each hold type (special figure 1, special figure 2), but in this embodiment, the same value is set regardless of the hold type. The big win determination table shows the determination reference value TH in the low probability state and the high probability state. In the jackpot random number determination in this embodiment, a determination reference value TH is determined within the range of values that the jackpot determination random number can take, and a determination (jackpot lottery) as to whether or not it is a jackpot is made based on the result of comparing the magnitude relationship between the jackpot determination random number and the determination reference value TH. As an example, a method is adopted in which a jackpot determination result is obtained when the value of the jackpot determination random number is within the range of "0 to the determination reference value TH", and a non-winning determination result is obtained in other cases.

[0215] And, as the determination reference value TH, two types are set: a determination reference value TH1 (205) used for determination in a low probability state and a determination reference value TH2 (658) used for determination in a high probability state. As shown in FIGS. 17 and 18, the determination reference value TH2 in the high probability state is made larger in value than the determination reference value TH1 in the low probability state, so that the winning probability of the jackpot is increased in the determination in the high probability state.

[0216] Note that, in the above, an example in which the lower limit value for jackpot determination in the jackpot random number determination is "0", that is, a case where a jackpot determination result is obtained if the jackpot determination random number is within the range of "0" to "the determination reference value TH" is illustrated, but the determination lower limit value can also be a numerical value larger than "0".

[0217] In step S411-2, the CPU 40a determines whether or not the jackpot determination random number is less than the determination lower limit value. The determination lower limit value is the lower limit value for jackpot determination (the lower limit value of the numerical range in which a determination result as a jackpot is obtained) as described above, and is, for example, "0". If the jackpot determination random number is less than the determination lower limit value, since it is certain that it is a non-winning, the processes in steps S411-3 to S411-7 described below are skipped and the jackpot random number determination process ends. Note that when the determination lower limit value = 0, it is usually impossible for the jackpot determination random number to take a value less than 0, so the process in step S411-2 is not essential. The process in step S411-2 is effective when the determination lower limit value is set to a value larger than 0.

[0218] If the jackpot determination random number is not less than the determination lower limit value in step S411-2, then in step S411-3, the CPU 40a determines whether the current gaming state is a high probability state.

[0219] If it is determined that it is not in the high probability state, then in step S411-4, the CPU 40a acquires the determination reference value TH1 for the low probability state in the jackpot determination table. On the other hand, if it is determined that it is in the high probability state, then in step S411-5, the CPU 40a acquires the determination reference value TH2 for the high probability in the jackpot determination table.

[0220] In step S411-6, the CPU 40a determines whether the jackpot determination random number is less than the determination reference value TH based on the determination reference value TH1 or the determination reference value TH2. If it is determined that the jackpot determination random number is less than the determination reference value TH, then in step S411-7, the CPU 40a updates the jackpot determination flag to 5AH and then ends the jackpot random number determination process. If it is determined that the jackpot determination random number is not less than the determination reference value TH, it passes step S411-6 and ends the jackpot random number determination process.

[0221] Note that when it is determined in step S411-2 that the jackpot determination random number is less than the determination lower limit value, and when it is determined in step S411-6 that the jackpot determination random number is not less than the determination reference value TH, the jackpot determination flag should be updated to a value indicating that it is not a jackpot (=5AH), specifically a loss (=00H). However, in the jackpot random number determination process of step S411, the process of updating the jackpot determination flag to 00H indicating a loss is not performed, but is performed in the process during the special symbol confirmation time of step S407.

[0222] (Symbol lottery process) FIG. 19 is a flowchart showing the symbol lottery process (step S412), and FIG. 20 is a diagram showing an example of the symbol table.

[0223] As shown in FIG. 20, the symbol table is provided for each jackpot lottery result. In the symbol table, the selection rate of the type of special symbol (jackpot type, losing type) is set for each jackpot lottery result. Here, within the symbol table, the numerical value stored for each type of special symbol subject to the lottery represents the allocation value (value representing the allocation) of the selection rate on the premise that the random number for special symbol determination can take 200 values from 0 to 199. According to the symbol table for jackpots, when winning the jackpot with special symbol 1, "jackpot 1" is determined as the jackpot type with a selection rate of 200 / 200, that is, it is always determined. Also, when winning the jackpot with special symbol 2, "jackpot 1" is determined as the jackpot type with a selection rate of 140 / 200, and "jackpot 2" is determined as the jackpot type with a selection rate of 60 / 200.

[0224] According to the symbol table for losses, when it is determined that there is a loss with special symbol 1, "loss 1" is determined as the loss type with a selection rate of 180 / 200, "loss 2" is determined as the loss type with a selection rate of 16 / 200, and "loss 3" is determined as the loss type with a selection rate of 4 / 200. Also, when it is determined that there is a loss with special symbol 2, "loss 1" is determined as the loss type with a selection rate of 180 / 200, "loss 2" is determined as the loss type with a selection rate of 10 / 200, and "loss 3" is determined as the loss type with a selection rate of 10 / 200.

[0225] In step S412-1, the CPU 40a selects the symbol table corresponding to the reserved type (special symbol 1, special symbol 2).

[0226] In step S412-2, the CPU 40a acquires the random number for special symbol determination and the jackpot determination flag. In step S412-3, the CPU 40a refers to the symbol table corresponding to the jackpot determination flag (jackpot / loss), and based on the random number for special symbol determination, determines the type of special symbol (jackpot type, loss type) by lottery.

[0227] In step S412-4, the CPU 40a stores the special symbol determination data corresponding to the type of the special symbol determined in step S412-3 in a predetermined area of the RAM 40c, and ends the special stop symbol creation process.

[0228] (Variable pattern lottery process) FIG. 21 is a flowchart showing the variable pattern lottery process (step S413). In step S413-1, the CPU 40a determines whether it is a big win. That is, based on the big win determination flag, it determines whether it is a big win (=5AH).

[0229] If it is determined in step S413-1 that it is not a big win (a loss), in step S413-2, the CPU 40a selects a loss variable pattern table and then proceeds to the variable pattern selection process in step S413-4. On the other hand, if it is determined in step S413-1 that it is a big win, in step S413-3, the CPU 40a selects a big win variable pattern table and then proceeds to the variable pattern selection process in step S413-4.

[0230] In step S413-4, the CPU 40a refers to the variable pattern table selected in step S413-2 or step S413-3 above, determines a variable pattern based on a random number for the variable pattern, and ends the variable pattern lottery process.

[0231] FIG. 22 is a diagram showing an example of a variable pattern lottery table. The variable pattern table is stored in the ROM 40b. In FIG. 22, the variable pattern table used in the time-saving state is illustrated, but actually, a variable pattern table used in the non-time-saving state is also provided.

[0232] As shown in Fig. 22, in the variation pattern lottery for the losing case, the variation patterns of lottery candidates (variation patterns that can be selected by lottery) are seven types: "Normal variation 1s", "Normal variation 12s1", "Normal variation 12s2", "Super reach 1", "Super reach 2", "Super reach 3", and "Super reach 4". Also, in the variation pattern lottery for the jackpot, the variation patterns of lottery candidates are four types: "Super reach 1", "Super reach 2", "Super reach 3", and "Super reach 4".

[0233] Here, among the above-mentioned variation patterns, in particular, "Normal variation 1s", "Normal variation 12s1", and "Normal variation 12s2" belong to the variation patterns corresponding to the so-called "losing" that are not selected in the jackpot case (hereinafter sometimes referred to as "losing variation patterns").

[0234] In the present embodiment, the variation pattern lottery for the losing case is performed using different variation pattern tables for each losing type (losing 1, 2, 3) regardless of Figs. 1 and 2 of the special drawing. Here, as described above, for each of the losing types of "losing 1", "losing 2", and "losing 3", the selection rates by the symbol lottery are considered to be different. "Losing 1" has the highest selection rate, and "losing 2" and "losing 3" have lower selection rates than "losing 1". That is, if the jackpot lottery result is "losing", in most cases, "losing 1" will be selected as the losing type.

[0235] Regarding the variation pattern lottery for Fig. 2 of the special drawing, for the variation pattern lottery when the losing type is "losing 1", a lottery according to the number of hold balls is performed. Therefore, among the variation pattern tables for Fig. 2 of the special drawing, different tables are prepared for each number of hold balls as the variation pattern table used when the losing type is "losing 1".

[0236] Here, in the variation pattern table, the numerical values stored for each variation pattern to be selected represent the distribution values (values representing the distribution) of the selection probabilities on the premise that the random numbers for variation pattern determination can take 1000 values from 0 to 9999. For example, in the variation pattern table for FIG. 1, in the table of "miss 1" and "number of hold balls = 0", the stored value for "normal variation 1s" is set to "10000", which means that the winning probability of "normal variation 1s" is "10000 / 10000". Showing the above distribution values as the stored values in the table is only for the convenience of explanation. In the actual variation pattern table, the judgment reference values such as those used in the above jackpot random number judgment will be stored. For example, for the above table of "miss 1" and "number of hold balls = 0", if, for example, "9999" is stored as the actual stored value (judgment reference value), then if the random number for the variation pattern is 9999 or less, "normal variation 1s" will be selected.

[0237] As can be seen with reference to the distribution values shown in FIG. 22, in the variation pattern lottery of FIG. 2 corresponding to the case of "miss 1", only "normal variation" is selected. Also, in the variation pattern lottery of FIG. 2 corresponding to the case of "miss 1", the shorter the variation time of the normal variation pattern is selected as the number of hold balls increases.

[0238] <5. Processing of the effect control board> Subsequently, the processing performed by the CPU 41a of the effect control board 41 of the present embodiment will be described. The processing of the CPU 41a mainly includes a main process (effect control side main process: FIG. 23) and a timer interrupt process (effect control side timer interrupt process: FIG. 24) started by a periodic interrupt.

[0239] [5.1 Effect control side main process] FIG. 23 is a flowchart showing the effect control side main process. First, in step S501, the CPU 41a performs necessary initial setting processes before the start of the game operation. Here, as the initial setting processes, for example, command reception interrupt setting, origin return processing of the movable accessory 50, initial setting of the CTC, permission of timer interrupt, and initial setting of register values inside the CPU including each part of the microcomputer are performed.

[0240] After finishing the above initial setting processes, the main loop processes of steps S504 to S511 are performed every predetermined time (16 ms), and otherwise, the effect software random number update process of step S503 is repeatedly performed.

[0241] In step S502, the CPU 41a refers to the main loop update counter and determines whether the main loop update cycle (counter value > 15), which is the trigger for executing the main loop process, has arrived. The main loop update counter is a counter that is incremented during the effect control side timer interrupt process described later, which is executed every 1 ms. In this embodiment, the main loop process is performed every 16 ms. In the determination process of step S502, the main loop update counter value is determined. If the value is greater than "15" (Yes in step S502), it is considered that the execution timing of the main loop process has arrived, and the processes of steps S504 to S511 are executed. Otherwise, until the main loop update cycle arrives (No in step S502), in step S503, the update of various effect lottery software random numbers used for lottery to determine the effect scenario is performed.

[0242] When the main loop update cycle arrives (Yes in step S502), in step S504, the CPU 41a clears the main loop update counter, and in step S505, the demo power saving mode process is executed. In the demo power saving mode process, the pre-guest waiting effect (demo start waiting display), the guest waiting effect (demo display), and the setting processes necessary for the power saving mode are executed.

[0243] In step S506, the CPU 41a executes effect switch input processing. In the effect switch input processing, the operation states of the aforementioned operation unit 14 (such as the effect button 14a, the cross key 14b, and the determination button 14c) are monitored. When an operation is detected, effect control processing corresponding to the operation is executed.

[0244] In step S507, the CPU 41a performs command analysis processing. In the command analysis processing, it is monitored whether an effect control command is stored in the command reception buffer. If an effect control command is stored, this command is read out, and effect processing corresponding to the read effect control command is executed. When an effect control command is transmitted from the main control board 40, it is stored in the command reception buffer of the RWM.

[0245] For example, when a variation pattern specification command and a decoration pattern specification command are received and stored in the reception buffer, in the command analysis processing, an effect scenario is determined based on the information included in the commands, and the data of the effect scenario (effect scenario data) is stored in the scenario setting area of the RWM. Note that in the effect scenario, a time schedule regarding at what timing and with what effect time width one or a plurality of types of effects appear is defined.

[0246] In step S508, the CPU 41a executes scenario update processing. In this scenario update processing, the value of the timer necessary for the execution of the effect scenario is updated, and processing for advancing the effect scenario based on the timer value is executed. A typical example of the above timer is an effect scenario timer that manages the time schedule regarding the occurrence timing of the effect. For example, within a variation period in which a special pattern is variably displayed and substantially within the same period, within a variation period in which a decoration pattern is variably displayed, on the time axis, a temporal schedule regarding what kind of effect, with what time width, and by what kind of effect means is presented is managed by this timer. This production scenario timer is also used in the LED drive data update process (step S510) and the movable object device operation update process (step S603) described later.

[0247] In step S509, the CPU 41a performs sound output processing. In the sound output processing, based on the production scenario data and the production scenario timer, data such as phrases and volume are output to the sound source IC described above, and a sound production is presented from the speaker 17. Thereby, a sound production along the production scenario is realized.

[0248] In step S510, the CPU 41a executes an LED drive data update process. In the LED drive data update process, based on the production scenario data and the production scenario timer, a control signal (LED data) for lighting the light display device 16a is created.

[0249] In step S511, the CPU 41a executes an LED output process. In this LED output process, the control signal (LED data) created in the LED drive data update process is output to the lamp driver unit 26b, and the light display device 16a is lit through the lamp driver unit 26b.

[0250] [5.2 Production Control Side Timer Interrupt Processing] FIG. 24 is a flowchart showing the production control side timer interrupt processing. The production control side timer interrupt processing is activated by an interrupt every fixed time (1 ms) from the CTC, and is executed by interrupting during the execution of the production control side main process.

[0251] In step S601, the CPU 41a saves the contents of the register in the stack area, and then in step S602, executes a button input state update process. In this button input state update process, the input state of the operation detection signal from the operation unit 14 is monitored, and when it is confirmed that the operation detection signal has been received, the detection information is stored in a predetermined area of the RWM.

[0252] In step S603, the CPU 41a executes movable object prop operation update processing. In this movable object prop operation update processing, processing for controlling the operation of the movable object prop 50 is performed based on the production scenario data and the production scenario timer. Note that the content of the processing to be executed as the movable object prop operation update processing in this step S603 will be described later again.

[0253] In step S604, the CPU 41a performs SOL·MOT output processing. In this SOL·MOT output processing, processing for outputting control data to the motor drive control unit 51 is performed based on the processing result in the movable object prop operation update processing. Thereby, the movable object production by the movable object prop 50 along the production scenario is realized. Note that the details of the output processing in this step S604 will also be described later again.

[0254] In step S605, the CPU 41a performs LCD command transmission processing. In this LCD command transmission processing, when there is an LCD command created in the scenario update processing (step S508), the LCD command is transmitted to the aforementioned VDP to execute image display control. Thereby, an image along the production scenario is displayed.

[0255] In step S606, the CPU 41a executes RTC information acquisition processing. In this RTC information acquisition processing, date and time information (RTC information) measured by the RTC is acquired. This RTC information is used when presenting an effect based on the RTC information.

[0256] In step S607, the CPU 41a increments the main loop update counter. This main loop update counter is reset in step S503 during the above-mentioned main production control processing and is incremented here.

[0257] In step S608, the CPU 41a restores the content of the register that was saved, ends the timer interrupt processing, and executes the main production control processing until the next timer interrupt occurs.

[0258] <6. Movable object device control as an embodiment> [6.1 Outline of the control method as an embodiment] With reference to FIGS. 25 and 26, the outline of the method for movable object device control as an embodiment will be described.

[0259] First, for comparison, FIG. 25 shows an outline of the configuration of a conventional movable object device control system. Here, as an example for explanation, a configuration is shown on the premise that the movable object device 50 is composed of two movable object devices 50x and 50y. Also, here, the control unit corresponding to the production control board 41 in the conventional configuration is shown as the production control board 41'.

[0260] In the conventional movable object device control system, the production control board 41' directly controls each motor driver (52x, 52y). The conventional production control board 41' (CPU 41a) performs a process of outputting a control signal to the motor drivers 52x and 52y in the production side timer interrupt process with a cycle of 1 ms described above. That is, the operations of the respective device motors (device motors 53x, 53y) are controlled with a time granularity of 1 ms cycle.

[0261] Also, as the operation control of the movable object device 50, control using the above-described position sensor group 55 (position sensors 55x, 55y) may be performed. Conventionally, however, as shown in the figure, the detection signals from the position sensors 55x and 55y are input to the production control board 41' via a para-silicon (parallel / serial) conversion unit 57. The CPU 41a of the production control board 41' determines whether the movable object device 50 has reached the target position at a cycle of 1 ms by the production control side timer interrupt process based on the detection signals input from the position sensors 55x and 55y as described above. In response to the determination that the movable object device 50 has reached the target position, a control signal for stopping the device motors 53x and 53y is output to the motor drivers 52x and 52y.

[0262] Here, in the conventional configuration as described above, the CPU 41a of the effect control board 41' outputs a control signal instructing the operation of the movable object motors 53x and 53y to the motor drivers 52x and 52y at a cycle of 1 ms. To realize such an operation, in the conventional configuration, the processing load of the effect control board 41' has a tendency to increase, and it has been forcing the developer to create control data every 1 ms. That is, it has caused an increase in the work load of the developer in realizing the movable object effect control.

[0263] Also, in the conventional configuration as described above, the control resolution of the movable object motors 53x and 53y in the time direction is regulated by the cycle of the timer interrupt process, specifically, a cycle of 1 ms. This has made it difficult to move the movable object effect 50 smoothly.

[0264] Further, in the conventional configuration, since the CPU 41a of the effect control board 41' executes the operation control of the movable object effect based on the detection signals of the position sensors 55x and 55y, the effect control board 41' requires a total of two communication systems: a communication system for outputting a control signal to the motor drivers 52x and 52y and a communication system for inputting the detection signals of the position sensors 55x and 55y.

[0265] Therefore, in the present embodiment, as the configuration of the movable object effect control system, a configuration using a motor drive control unit 51 as shown in FIG. 26 is adopted. Although details will be described later, the motor drive control unit 51 is configured by, for example, an LSI (Large Scale Integration), and has a function of generating and outputting control signals for the motor drivers 52x and 52y necessary to realize a series of operations of the movable object effect 50 in response to the input of a control command Cd designating the series of operations from the outside.

[0266] The series of operations mentioned here refers to, for example, the operation of the movable object device 50 from the start of movement to the stop, or the operation from the start to the end of the movement of the movable object device 50 in one direction when the movable object device 50 is reciprocated, etc., which means an operation with a certain continuity of the movable object device 50. As this series of operations, it is sufficient if it is at least an operation of the movable object device 50 in a period longer than one cycle of the timer interrupt.

[0267] In the following description, the control signal input to the motor drivers 52x and 52y is referred to as a "driver control signal".

[0268] The effect control board 41 (CPU 41a) in the present embodiment outputs a control command Cd corresponding to the operation pattern to the motor drive control unit 51 in response to the identification of the operation pattern of the movable object device 50 to be executed based on the above-described effect scenario data and the effect scenario timer. The motor drive control unit 51 generates a driver control signal corresponding to the control command Cd input from the effect control board 41 and outputs it to the motor drivers 52x and 52y.

[0269] With the above configuration, in the gaming machine 1 of the present embodiment, when realizing a series of operations of the movable object device 50, the CPU 41a of the effect control board 41 does not need to output a driver control signal to the motor drivers 52x and 52y at a cycle of 1 ms as in the conventional case. Therefore, it is possible to reduce the processing load of the effect control board 41 in realizing the movable object device control, and it is also possible to reduce the developer burden. As will be described later, in the case of the present embodiment, the developer only needs to create data in which operation definitions are made for each divided operation constituting the operation pattern for the operation pattern of the movable object device 50 to be realized, and it is possible to significantly reduce the work burden compared to the case of creating control data every 1 ms as in the conventional case.

[0270] In addition, according to the gaming machine 1 of the present embodiment, the time-direction control resolution of the accessory motors 53x and 53y is no longer restricted by the cycle of the timer interrupt process (1 ms cycle) as in the prior art, so that the movable accessory 50 can be moved smoothly. Specifically, in the present embodiment, by making it possible to use the microstep drive mode described later, the movable accessory 50 can be moved smoothly. As a result, it is possible to improve the effect of the presentation using the movable accessory 50.

[0271] Furthermore, in the present embodiment, the motor drive control unit 51 responds to the input of detection signals from position sensors provided for the movable accessory 50, such as the position sensors 55x and 55y, and has a function of generating and outputting a motor control signal for moving the target movable accessory 50 to the sensor position in response to an external control command Cd. Therefore, when realizing the accessory operation of moving the movable accessory 50 to the sensor position, it is no longer necessary to input the detection signals of the position sensors 55x and 55y to the effect control board 41 as in the prior art.

[0272] In the present embodiment, when realizing the operation of moving the movable accessory 50 to the sensor position, a corresponding control command Cd may be transmitted from the effect control board 41 to the motor drive control unit 51 in the same manner as when realizing other series of operations. Therefore, according to the present embodiment, when realizing various series of operations of the movable accessory 50 including the operation of moving the movable accessory 50 to the sensor position as described above, only one communication system needs to be provided between the effect control board 41 and the motor drive control unit 51, and the number of necessary communication systems can be reduced compared to the prior art.

[0273] [6.2 About the Motor Drive Control Unit] FIG. 27 is a block diagram showing a schematic internal configuration example of the motor drive control unit 51. The motor drive control unit 51 in this embodiment is capable of simultaneously and parallelly controlling a plurality of motor drivers provided as a group of motor drivers 52. Specifically, the motor drive control unit 51 in this example is capable of simultaneously and parallelly controlling four motor drivers. In other words, the motor drive control unit 51 in this example has four control systems as the control system of the motor driver.

[0274] In this embodiment, the control systems of the motor drivers included in the motor drive control unit 51 are expressed as "axes", and the four control systems are respectively denoted as "X-axis", "Y-axis", "Z-axis", and "U-axis".

[0275] In the figure, among these four control systems of the X-axis, Y-axis, Z-axis, and U-axis included in the motor drive control unit 51, only the configuration of the control system of the X-axis is shown as the "circuit for X-axis" as a representative. Since the configurations of the control systems of the other Y-axis, Z-axis, and U-axis (in the figure, "circuit for Y-axis", "circuit for Z-axis", "circuit for U-axis") are the same as that of the circuit for X-axis, the illustration thereof is omitted.

[0276] As shown in the figure, the motor drive control unit 51 has an I / F (interface) unit 71. The I / F unit 71 is a communication interface unit for performing data communication according to a predetermined data communication standard between an external device, particularly the production control board 41 in this embodiment. This I / F unit 71 is a communication interface unit commonly provided for the circuit for X-axis, the circuit for Y-axis, the circuit for Z-axis, and the circuit for U-axis. In other words, the external device of the motor drive control unit 51 can communicate individually with these circuits for X-axis, circuit for Y-axis, circuit for Z-axis, and circuit for U-axis via the I / F unit 71. Note that as the I / F unit 71, for example, one corresponding to I2C (Inter-Integrated Circuit) bus communication or SPI (Serial Peripheral Interface) bus communication can be considered to be used.

[0277] As shown in the figure, the X-axis circuit includes a command register control circuit 72, a register section 73, a pre-register section 74, a start / stop control circuit 75, an acceleration / deceleration pulse generation circuit 76, a multiplication / division circuit 77, an output form conversion circuit 78, a remaining pulse number counter 79, a current up / down control circuit 80, and a general-purpose input / output control circuit 81. Also, the X-axis circuit has a pulse signal output terminal OUTx and a rotation direction output terminal DIRx as terminals for outputting control signals to the motor driver. In this embodiment, the motor driver is configured to output a pulse signal indicating the period of the drive pulse of the utility motor and a rotation direction indication signal indicating the rotation direction (CW / CCW) of the utility motor. The pulse signal output terminal OUTx is the terminal for outputting the above pulse signal, and the rotation direction output terminal DIRx is the terminal for outputting the above rotation direction indication signal. Hereinafter, the above pulse signal output from the pulse signal output terminal OUT is referred to as the "OUT signal", and the above rotation direction indication signal output from the rotation direction output terminal DIR is referred to as the "DIR signal".

[0278] Furthermore, the X-axis circuit has a plurality of general-purpose input / output terminals shown as "P0x", "P1x", "P2x", "P3x" in the figure. These general-purpose input / output terminals are terminals for which it is possible to select and set whether to input or output any signal. The setting of which signal to input or output for each general-purpose input / output terminal can be performed by setting the setting register in the register section 73 described later.

[0279] Here, the above-described pulse signal output terminal OUT, rotation direction output terminal DIR, and plurality of general-purpose input / output terminals P are provided for each axis, and the terminals for each axis are distinguished by attaching an alphabet for each axis to the end of the symbol. Specifically, for the pulse signal output terminals OUT and rotation direction output terminals DIR in the Y-axis circuit, Z-axis circuit, and U-axis circuit, the symbols are represented as "OUTy", "DIRy", "OUTz", "DIRz", "OUTu", "DIRu", respectively. Also, for the general-purpose input / output terminals P0, P1, P2, P3 in the Y-axis circuit, Z-axis circuit, and U-axis circuit, they are represented as "P0y", "P1y", "P2y", "P3y", "P0z", "P1z", "P2z", "P3z", "P0u", "P1u", "P2u", "P3u", respectively.

[0280] In the X-axis circuit, the command register control circuit 72 can write and read various control commands Cd and status information for a plurality of registers provided in the register unit 73 and a plurality of pre-registers provided in the pre-register unit 74 based on an instruction from an external device (production control board 41) input via the I / F unit 71.

[0281] Here, the role of the pre-registers in the pre-register unit 73 and the control using the pre-registers will be described later again.

[0282] The following various registers are provided in the register unit 73 as registers for storing the control command Cd. · RFL register: A register for storing a control command Cd (hereinafter referred to as "RFL command") for specifying the FL speed (initial speed, stop speed) of the accessory motor · RFH register: A register for storing a control command Cd (hereinafter referred to as "RFH command") for specifying the FH speed (operating speed) of the accessory motor · RMV register: A register for storing a control command Cd (hereinafter referred to as "RMV command") for specifying the number of output pulses for stopping the accessory motor (the target movement amount of the movable body accessory 50) in the positioning operation mode described later · RMG register: A register that stores a control command Cd (hereinafter referred to as the "RMG command") for specifying the speed multiplication factor of the actuator motor · RDP register: A register that stores a control command Cd (hereinafter referred to as the "RDP command") for specifying the slow-down point (a value that determines the remaining number of pulses at which deceleration starts) · RUR register: A register that stores a control command Cd (hereinafter referred to as the "RUR command") for specifying the acceleration rate of the actuator motor (the larger the value, the longer the acceleration time and the gentler the acceleration) · RDR: A register that stores a control command Cd (hereinafter referred to as the "RDR command") for specifying the deceleration rate of the actuator motor (the larger the value, the longer the deceleration time and the gentler the deceleration)

[0283] External devices such as the effect control board 41 can, by issuing a register write command, instruct the command-register control circuit 72 to write the corresponding control command Cd to each of the above registers. That is, it is possible to instruct to write each of the various control commands Cd related to the actuator motor control as described above to the corresponding register

[0284] In addition, the register section 73 is also provided with the following registers as registers for storing values related to the actuator motor control · RPLS: A register in which the remaining number of pulses is stored. In the positioning operation mode, the number of output pulses stored in the above-mentioned RMV register is set as the initial value, and thereafter, it is decremented by a remaining number of pulses counter 79 described later

[0285] In addition to the registers exemplified above, the register section 73 is also provided with setting registers for performing environment settings, operation mode settings, etc., and status registers for storing values indicating the operation state of the motor drive control section 51

[0286] In the present embodiment, the motor drive control unit 51 can switch between the above-described positioning operation mode and the sensor input stop mode as the drive control mode of the accessory motor. The positioning operation mode is a mode in which the accessory motor is stopped when the number of drive pulses of the target accessory motor in the accessory motor group 53 reaches a predetermined number of output pulses. This can be rephrased as a mode for moving the target movable body accessory 50 by a predetermined target movement amount. The sensor input stop mode is a mode in which the target accessory motor is stopped when it is determined that the target movable body accessory 50 has reached the position of the position sensor based on the detection signal of the target position sensor in the position sensor group 55.

[0287] The switching setting between the positioning operation mode and the sensor input stop mode is realized by setting the control command Cd for a predetermined setting register in the register unit 73. Specifically, the switching setting between the positioning operation mode and the sensor input stop mode can be performed by setting the control command Cd for the RMD register provided as a register for setting the operation mode in the register unit 73. In this example, depending on the control command Cd (hereinafter referred to as the "RMD command") for the RMD register, not only the positioning operation mode and the sensor input stop mode can be specified, but also the rotation direction (CW / CCW) of the accessory motor can be specified. In addition, the RMD command of this example can also specify which general-purpose input / output terminal is to be used as the sensor signal input terminal when specifying the sensor input stop mode. Specifically, the motor drive control unit 51 of this example is configured to select, from among the general-purpose input / output terminals P0 to P3, the terminal for inputting the detection signal from the position sensor in the sensor input stop mode, and the above RMD command is used to specify which general-purpose input / output terminal is to be used as the sensor signal input terminal when specifying the sensor input stop mode.

[0288] The command register control circuit 72 controls the start / stop control circuit 75, the acceleration / deceleration pulse generation circuit 76, and the multiplication frequency division circuit 77 based on the control command Cd related to the actuator motor control stored in the register unit 73, so as to generate and output a driver control signal (the above-mentioned OUT signal and DIR signal) for realizing the operation of the movable body actuator 50 according to the instruction of the control command Cd.

[0289] The start / stop control circuit 75 controls the pulse generation / output operation by the acceleration / deceleration pulse generation circuit 76 based on the instruction from the command register control circuit 72. The acceleration / deceleration pulse generation circuit 76 is a circuit that generates and outputs a pulse signal serving as the basis of the OUT signal. Specifically, for example, when the actuator motor is rotated forward (CW), a pulse signal with positive polarity is generated, and when the actuator motor is rotated backward (CCW), a pulse signal with negative polarity is generated, etc., and a pulse signal with a polarity corresponding to the rotation direction of the actuator motor is generated and output.

[0290] When a start command is input from an external device via the I / F unit 71, the command register control circuit 72 outputs a start instruction signal to the start / stop control circuit 75. The start / stop control circuit 75 starts the output of the pulse signal to the acceleration / deceleration pulse generation circuit 76 according to this start instruction signal. The timing at which the output of the pulse signal to the acceleration / deceleration pulse generation circuit 76 is started in this way corresponds to the timing at which the driving of the actuator motor is started.

[0291] Also, the start / stop control circuit 75 stops the output of the pulse signal by the acceleration / deceleration pulse generation circuit 76 based on the instruction from the command register control circuit 72. Here, as the timing for stopping the output of the pulse signal by the acceleration / deceleration pulse generation circuit 76, when the number of output pulses of the OUT signal reaches the "number of output pulses" set in the aforementioned RMV register during the positioning operation mode described above, and when the target movable object 50 reaches the position of the target position sensor during the sensor input stop mode described above can be cited.

[0292] During the sensor input stop mode, the command register control circuit 72 determines whether or not the target movable object 50 has reached the position of the position sensor based on the detection signal of the position sensor (refer to "positioning sensor signal" in the figure) input from the general-purpose input / output terminal P specified in advance by the aforementioned RMD command. Then, in response to determining that the target movable object 50 has reached the position of the position sensor, a stop instruction signal is output to the start / stop control circuit 75. In response to this stop instruction signal, the acceleration / deceleration pulse generation circuit 76 stops the output of the pulse signal.

[0293] Also, during the positioning operation mode, the command register control circuit 72 outputs a stop instruction signal to the start / stop control circuit 75 based on the count value (refer to "RPLS" in the figure) by the remaining pulse number counter 79. The command register control circuit 72 in this example outputs the value of the number of output pulses stored in the aforementioned RMV register to the remaining pulse number counter 79 (refer to "RMV" in the figure). The remaining pulse number counter 79 inputs the pulse signal with adjusted magnification output by the magnification frequency division circuit 77 to be described later, and counts the remaining pulse number (that is, the difference value between the number of output pulses defined as the target by the control command Cd and the current number of output pulses) by subtracting the pulse count value of the pulse signal with adjusted magnification from the above-mentioned number of output pulses input from the command register control circuit 72. Here, the number of pulses of the pulse signal with adjusted magnification is the same as the number of pulses of the OUT signal. That is, the remaining pulse number counter 79 counts the remaining pulse number based on the OUT signal.

[0294] When in the positioning operation mode, the command register control circuit 72 outputs a stop instruction signal to the start / stop control circuit 75 in response to the remaining pulse count input from the remaining pulse count counter 79 becoming zero. The command register control circuit 72 also performs a process of storing the value of the remaining pulse count in a predetermined status register (RPLS register).

[0295] Here, the start / stop control circuit 75 outputs a value (hereinafter referred to as "drive status value SRUN") indicating the drive control status of the actuator motor shown as "SRUN" in the figure based on the start instruction signal and stop instruction signal from the command register control circuit 72. This drive status value SRUN is a value for identifying the start timing and end timing (stop timing) of the drive control of the actuator motor. In this example, for example, "1" (H level) means that the motor is driving, and "0" (L level) means that the motor is stopped. In this example, the start / stop control circuit 75 raises the drive status value SRUN from "0" to "1" at the timing when the start instruction signal from the command register control circuit 72 is input, and lowers the drive status value SRUN from "1" to "0" at the timing when the stop instruction signal from the command register control circuit 72 is input.

[0296] The command register control circuit 72 performs a process of storing the drive status value SRUN output by the start / stop control circuit 75 in a predetermined status register (hereinafter referred to as "SRUN register") provided in the register section 73. Thereby, the effect control board 41 can inquire about the status information of whether the actuator motor is driving or stopped by issuing a register read command instructing the reading of the value of the SRUN register to the command register control circuit 72.

[0297] The acceleration / deceleration pulse generation circuit 76 generates and outputs a pulse signal at a frequency based on an instruction from the start / stop control circuit 75 and an instruction from the command register control circuit 72.

[0298] The frequency of the pulse signal generated and output by the acceleration / deceleration pulse generation circuit 76 is controlled based on the aforementioned RFL command (FL speed), RFH command (FH speed), RUR command (acceleration rate), RDP command (slowdown point), and RDR command (deceleration rate).

[0299] Specifically, in response to the issuance of the aforementioned start command, the acceleration / deceleration pulse generation circuit 76 is instructed by the command register control circuit 72 with the FL speed indicated by the RFL command, the acceleration rate indicated by the RFH command, the FH speed indicated by the RFH command, and the deceleration rate indicated by the RDR command. In response to the output start instruction of the pulse signal from the start / stop control circuit 75, the acceleration / deceleration pulse generation circuit 76 first starts outputting a pulse signal at a frequency corresponding to the FL speed, and increases the frequency of the pulse signal at a frequency increase rate corresponding to the acceleration rate. Then, in response to the frequency of the pulse signal reaching the frequency corresponding to the FL speed, the frequency of the pulse signal is maintained at the frequency corresponding to the FL speed. Thereafter, when it reaches the timing of the slowdown point indicated by the RDP command, a deceleration instruction is given to the acceleration / deceleration pulse generation circuit 76 from the command register control circuit 72. In response to this deceleration instruction, the acceleration / deceleration pulse generation circuit 76 decreases the frequency of the pulse signal at a frequency decrease rate corresponding to the deceleration rate. And in response to the output stop instruction of the pulse signal from the start / stop control circuit 75, the output of the pulse signal is stopped.

[0300] Thereby, the operation of the target actuator motor can be controlled in the manner specified by the RFL command (FL speed), RFH command (FH speed), RUR command (acceleration rate), RDP command (slowdown point), and RDR command (deceleration rate).

[0301] The frequency division circuit 77 divides the frequency of the pulse signal output from the acceleration / deceleration pulse generation circuit 76 based on an instruction from the command register control circuit 72. Specifically, the command register control circuit 72 instructs the frequency division circuit 77 of the speed magnification indicated by the aforementioned RMG command. The frequency division circuit 77 divides the frequency of the pulse signal input from the acceleration / deceleration pulse generation circuit 76 by a frequency division ratio corresponding to the instructed speed magnification. Thereby, speed magnification adjustment according to the RMG command can be realized for the operating speed (rotational speed) of the actuator motor.

[0302] The output form conversion circuit 78 generates an OUT signal and a DIR signal based on the pulse signal output from the frequency division circuit 77. As understood from the previous description, the pulse signal in this example has a polarity corresponding to the rotational direction of the actuator motor. The output form conversion circuit 78 generates and outputs a DIR signal based on the polarity of the input pulse signal, and generates and outputs a signal obtained by absolute - valuing the pulse signal as the OUT signal.

[0303] The general - purpose input / output control circuit 81 performs signal input / output control for the general - purpose input / output terminals P0x to P3x based on an instruction from the command register control circuit 72. Examples of signals that can be assigned to the general - purpose input / output terminals P0x to P3x include the aforementioned drive status value SRUN, the current up / down signal CDWN output from the current up / down control circuit 80 described below, the positioning sensor signal, and the like. Output to the outside is possible for the drive status value SRUN and the current up / down signal CDWN. Also, at least input from the outside is possible for the positioning sensor signal. Here, according to the specifications of this example, the current up / down signal CDWN can only be output from the general - purpose input / output terminal P1 or P3.

[0304] The current up-down control circuit 80 performs control to realize a current up function and a current down function (hereinafter, when collectively referred to, it is expressed as "current up / down function").

[0305] The current up function mentioned here is not to output the drive pulse of the utility motor immediately at the timing of the start command, but to delay the output of the drive pulse for a predetermined period from the timing of the start command. By this function, it is possible to obtain a delay period for increasing the output current value of the motor driver to the current value during driving (driving current value) before applying the drive pulse to the utility motor. If the drive pulse is applied before the output current value of the motor driver stabilizes, there is a risk that the utility motor will lose synchronization. Therefore, the above-mentioned delay period is provided to prevent loss of synchronization. Also, by providing the above-mentioned delay period, it is possible to obtain a period for stabilizing the mechanism (movable body utility 50) at the excitation position, and thus loss of synchronization of the utility motor can also be prevented in this regard. Hereinafter, the above-mentioned delay period is referred to as the "current up period".

[0306] The current down function is a function of maintaining the output current value of the motor driver at the above-mentioned driving current value for a predetermined period from the driving stop timing of the utility motor (the timing of stopping the application of the drive pulse), and then decreasing it to the current value during standby (standby current value). By providing a period for maintaining the output current value of the motor driver at the driving current value for a predetermined period from the driving stop timing of the utility motor in this way, it is possible to ensure the time for the utility motor to stop surely. Also, by decreasing the output current of the motor driver from the driving current value to the standby current value, the heat generation of the utility motor can be reduced. Hereinafter, the period for maintaining the output current value of the motor driver at the driving current value from the driving stop timing of the utility motor as described above is referred to as the "current down period".

[0307] The current up-down control circuit 80 generates and outputs a current up-down signal CDWM signal for realizing the current up-down function as described above.

[0308] Figure 28 is an operation explanatory diagram of the current up-down control circuit 80. Here, together with the current up-down signal CDWM, the above-described drive status value SRUN and OUT signal are also shown.

[0309] In the figure, the timing indicated as "CSTA" represents the timing when the drive start of the actuator motor is instructed by the start command. The current up-down control circuit 80 outputs a start instruction permission signal to the start / stop control circuit 75 in response to the elapse of a previously instructed current up period from the timing of the drive start instruction by this start command. The timing of the drive start instruction by the start command is instructed from the command register control circuit 72 to the current up-down control circuit 80.

[0310] The start / stop control circuit 75, in a state where the current up-down function is enabled, not only the start instruction signal from the command register control circuit 72 but also in response to the input of the above-described start instruction permission signal, gives an instruction to start the pulse signal output by the acceleration / deceleration pulse generation circuit 76 As a result, as shown in the figure, the OUT signal starts pulse output after the elapse of a predetermined current up period from the timing of the drive start instruction by the start command.

[0311] Regarding the drive stop side, as described above, the start / stop control circuit 75 stops the pulse generation / output operation of the acceleration / deceleration pulse generation circuit 76 at the timing indicated by the stop instruction signal from the command register control circuit 72.

[0312] Also, the current up-down control circuit 80 generates the current up-down signal CDWN as follows. First, in response to the arrival of the timing of the drive start instruction by the start command, the current up-down signal CDWN is changed from the OFF level (e.g., L level) to the ON level (e.g., H level). Then, thereafter, when the stop timing of the pulse output is instructed from the command register control circuit 72, the current up-down signal CDWN is changed from the ON level to the OFF level in response to the elapse of a predetermined current down period from the stop timing of the pulse output. For confirmation, it should be noted that the stop timing of the above pulse output is the same timing as the output timing of the above-mentioned stop instruction signal from the command register control circuit 72 to the start / stop control circuit 75.

[0313] Here, in this example, the ON / OFF of the current up-down function, the current up period, and the current down period can be set by the control command Cd from an external device via the I / F unit 71. The information on the ON / OFF of the current up-down function and the information on the current up period and the current down period set by the control command Cd as described above are instructed from the command register control circuit 72 to the current up-down control circuit 80.

[0314] In the gaming machine 1, the current up-down function is realized based on the current up-down signal CDWN generated as described above. However, a specific method and configuration as an embodiment for realizing the current up-down function (control of the output current value of the motor driver) based on this current up-down signal CDWN will be described later again.

[0315] Here, as described with reference to FIG. 27, in this embodiment, the command register control circuit 72 determines whether or not the target movable body fixture 50 has reached the position of the position sensor based on the detection signal from the target position sensor among the position sensor group 55 in the sensor input stop mode. In the motor drive control unit 51 of this example, the determination conditions for such determination of reaching the position sensor can be adjusted. Specifically, in this example, the determination of reaching the position sensor is made such that a determination result of reaching the position sensor is obtained when the detection signal of the position sensor maintains the ON level for a specified time or more. At this time, the above-mentioned specified time can be adjusted. This adjustment can be performed by a control command Cd from an external device via the I / F unit 71. In this example, the above-mentioned specified time is set, for example, between 1.0 ms and 2.0 ms. Desirably, the specified time is approximately 1.2 ms. If the above-mentioned specified time is too short, an erroneous determination may be made that the position sensor has been reached even though it has not actually reached the position sensor due to noise. Conversely, if the specified time is too long, a determination omission of reaching the position sensor may occur. Therefore, by appropriately setting the above-mentioned specified time, the accuracy of the determination of reaching the position sensor can be improved.

[0316] [6.3 Control Data Creation Method as an Embodiment] With reference to FIGS. 29 to 33, an example of control data to be created to realize the movable body fixture control as an embodiment and a method for creating the control data will be described.

[0317] FIG. 29 is an explanatory diagram of various control data used to realize the movable body fixture control as an embodiment. As shown in the figure, as various control data used to realize the movable body fixture control as an embodiment, there are three types of data: fixture sub-scenario data D1, classification operation management data D2, and control command management data D3.

[0318] The developer creates these accessory sub-scenario data D1, classification operation management data D2, and control command management data D3 using the computer device 100. As the computer device 100, for example, a computer device capable of software processing such as a personal computer, a tablet terminal, a smartphone, etc. is used.

[0319] The developer stores the created accessory sub-scenario data D1, classification operation management data D2, and control command management data D3 in the ROM 41b on the effect control board 41. The CPU 41a of the effect control board 41 controls the above-described motor drive control unit 51 based on the accessory sub-scenario data D1, classification operation management data D2, and control command management data D3 stored in the ROM 41b in this way, thereby realizing the operation of the movable accessory 50 along the effect scenario.

[0320] FIG. 30 is an explanatory diagram of an example of the data structure of the accessory sub-scenario data D1. In the effect using the movable accessory 50, usually, as the operation patterns of the movable accessory 50, a plurality of types of operation patterns to be expressed are defined. For example, in response to cases such as the operation pattern to be expressed at the time of jackpot notification, the operation pattern to be expressed at the time of sure change notification, and when a specific operation is detected, and for cases where the operation of the movable accessory 50 with different operation patterns for each scene during the game is to be expressed, a plurality of types of operation patterns of the movable accessory 50 are defined. The accessory sub-scenario data D1 is data for managing the operation of the movable accessory 50 in units of such operation patterns. Note that the unit of the operation pattern can be arbitrarily determined, and in this embodiment, at least one operation pattern may include one or more of the operation parts described later.

[0321] Also, for the effect using the movable accessory 50, there may be an effect of driving a plurality of movable accessories 50 simultaneously. In such a case, for the operation pattern, it is also possible to define the operations of those plurality of movable accessories 50 as one operation pattern.

[0322] In the figure, only the management data for some of the operation patterns among the operation patterns managed by the accessory sub-scenario data D1 stored in the ROM 41b are extracted and shown. Specifically, only the data for the three operation patterns of "B0_Combination", "B02_Gimmick", and "B03_When using △○×□ chance item" are shown.

[0323] In the accessory sub-scenario data D1, for the management data for each operation pattern, the identification information of the "classified operation" is stored for each "classified operation" included in the operation pattern. For example, the operation pattern of "B0_Combination" is defined to include four "classified operations" of "Excitation ON", "B01_No1", "B01_No1_wait", and "B01_No2". As shown in the figure, the management data of "B0_Combination" stores "Excitation ON", "B01_No1", "B01_No1_wait", and "B01_No2" as the identification information of these classified operations. Also, the operation pattern of "B02_Gimmick" is defined to include four "classified operations" of "Excitation ON", "B02_No1", "B02_No1_wait", and "B02_No2~3", and the management data of "B02_Gimmick" stores "Excitation ON", "B02_No1", "B02_No1_wait", and "B02_No2~3" as the identification information of these classified operations.

[0324] Also, for the management data for each operation pattern, the information of "operation type" is associated with each classified operation. This operation type information describes the operation type to be executed by the CPU 41a. As shown in the figure, when "operation type = operation call" is described, the CPU 41a calls the data of the corresponding classified operation from the classified operation management data D2 based on the identification information of the classified operation associated with the operation type information.

[0325] Figure 31 is an explanatory diagram of an example of the data structure of the classified operation management data D2. The classification operation management data D2 is data that manages, for each classification operation, the information used to realize that classification operation. In the figure, among all the classification operations, only the management data for the three classification operations of "B01_No1", "B01_No1_wait", and "B01_No2" exemplified in FIG. 30 are extracted and shown.

[0326] In the classification operation management data D2, for the management data for each classification operation, information on the "operation type" included in that classification operation is stored. Any of the information of "drive control unit operation", "waiting for the end of the drive control unit operation", and "standby" can be stored in this operation type. The drive control unit operation means the operation of the motor drive control unit 51, specifically, the operation of the motor drive control unit 51 that issues and executes the aforementioned control commands Cd (RFL command, RFH command, RMV command, RMG command, RDP command, RUR command, RDR command, start command, etc.). The waiting for the end of the drive control unit operation means waiting for the end of the operation executed by the motor drive control unit 51 in response to such a control command Cd.

[0327] And in the management data for each classification operation, information on "steps" is associated with each piece of information on the operation type. Here, the unit of the value described in "steps" is the time for one timer interrupt (1 ms in this example). Also, among the information on the operation type, information on the "part name" is associated with the operation type of "drive control unit operation".

[0328] In the illustrated example, in the management data of "B01_No1", the first line is set as the line with the operation type = drive control unit operation, and the second and third lines are set as the lines with the operation type = waiting for the end of the drive control unit operation. For the first line with the operation type = drive control unit operation, "1" is described as the information of "step", and the name information of "[C44_201_XY_TAMA_B01]{ball}TY106_pre-change △○×□ ball gimmick notice_combined No1_forward XY axis data" is described as the part name. Also, for the second and third lines with the operation type = waiting for the end of the drive control unit operation, "1000" is described as the information of "step".

[0329] Also, since the management data of "B01_No1_wait" is a standby operation, it only has a line with the operation type = standby. As shown in the figure, "2500" is described as the value of "step".

[0330] In the management data of "B01_No2", the first line is set as the line with the operation type = drive control unit operation, and the second and third lines are set as the lines with the operation type = waiting for the end of the drive control unit operation. For the first line with the operation type = drive control unit operation, "1" is described as the information of "step", and the name information of "[C44_201_XY_TAMA_B01]{ball}TY106_pre-change △○×□ ball gimmick notice_combined No2_backward XY axis data to sensor" is described as the part name. Also, for the second and third lines with the operation type = waiting for the end of the drive control unit operation, "1000" is described as the information of "step".

[0331] Here, in the management data of "B01_No1" and "B01_No2", the reason why two lines are provided for waiting for the end of the drive control unit operation is that the operation pattern of "B0_combination" including the classified operations of these "B01_No1" and "B01_No2" is defined as an operation pattern realized by the operations of the two movable body fixtures 50 of the X-axis and the Y-axis. In this case, since the operation of the movable member 50 is controlled by transmitting control commands Cd corresponding to the X-axis circuit and the Y-axis circuit in the motor drive control unit 51, two lines for waiting for the end of the drive control unit operation are provided so that the drive end timings of the component motors of the X-axis circuit and the Y-axis circuit can be monitored individually, and the operation waiting time (value of "step") for each axis can be determined.

[0332] In the management data for each classified operation, for the rows where the operation type = drive control unit operation, the CPU 41a reads out the source code associated with the name information from the control command management data D3 based on the name information described in "part name", and performs a process of transmitting the corresponding control command Cd to the motor drive control unit 51 according to the source code. When name information corresponding to the motor control operations of multiple axes is described as "part name" as in the above management data of "B01_No1" and "B01_No2", the control command management data D3 describes the source code for transmitting the control commands Cd for each of those axes in association with the name information. By transmitting the corresponding control command Cd to the motor drive control unit 51 according to the source code, the drive control of the defined component motors (i.e., the operation of the movable member 50) is realized for each axis.

[0333] Also, for the rows where the operation type = waiting for the end of the drive control unit operation, the CPU 41a performs an operation end confirmation process according to the value described in "step". Specifically, when the control command Cd (including the start command described above) is transmitted according to the information of "part name" in the row where the operation type = drive control unit operation, it is determined whether the status of the motor drive control unit 51 has changed to the drive stop status within the time specified by the value of "step" in the row where the operation type = waiting for the end of the drive control unit operation. Here, when there are multiple rows with operation type = waiting for the drive control unit operation to end, such as "B01_No1" and "B01_No2", the CPU 41a performs the above confirmation process for each axis based on the "step" values of those rows. Specifically, for each axis, it queries the drive status value SRUN described above, and determines whether the drive status value SRUN has changed to a value indicating drive stop within the time specified by the "step" value. At this time, it is predefined which row's "step" value to refer to for each axis. For example, among the multiple rows with operation type = waiting for the drive control unit operation to end, it is conceivable to assign the X-axis, Y-axis, Z-axis, and U-axis in order from the row with the youngest row number.

[0334] Here, in this embodiment, as a result of the above confirmation process, if the status of the motor drive control unit 51 does not change to drive stop within the time specified by the "step" value, fail-safe processing is performed, which will be described later in detail.

[0335] In addition, for the row with operation type = standby, the CPU 41a performs a process of waiting for the standby time indicated by the "step" value.

[0336] Note that in the management data for each divided operation shown in the figure, among the information associated with the operation type information, "excitation" and "speed" are information described for the management of the developer in this example, and are not the information referred to by the CPU 41a in the process of controlling the movable body device 50.

[0337] Here, as understood from the above description, the operation of the movable body device 50 can be roughly classified in units of operation patterns, and further, each operation pattern can be divided in units of divided operations. And among the divided operations that make up the operation pattern, there are operations defined as a series of device motor operations (that is, the operations of the movable body device 50) realized by instructing the control command Cd to the motor drive control unit 51, such as "B01_No1" and "B01_No2". In the present embodiment, a series of operations of the movable body component 50 realized by instructing a control command Cd to the motor drive control unit 51, which are the divided operations constituting the operation pattern like the divided operations of "B01_No1" and "B01_No2", shall be referred to as "operation parts". In this case, it can be paraphrased that the information described in the "part name" in the divided operation management data D2 is the identification information of the "operation part".

[0338] FIG. 32 is an explanatory diagram of an example of the data structure of the control command management data D3. The control command management data D3 is data for managing the control command Cd to be transmitted to the motor drive control unit 51 for each operation part. In FIG. 32, only the control command management data for some of the defined operation parts is extracted and illustrated. Specifically, only the control command management data for the operation part with the part name = "[C44_201_XY_TAMA_B01]{sphere}TY106_before variation △○×□ ball gimmick notice_combination No1_forward rotation XY axis data" in "B01_No1", the operation part with the part name = "[C44_201_XY_TAMA_B01]{sphere}TY106_before variation △○×□ ball gimmick notice_combination No2_reverse rotation XY axis data to sensor" in "B01_No2", and the operation part with the part name = "[C44_201_X_TAMA_B02]{sphere}TY106_before variation △○×□ large ball gimmick notice_No1_forward rotation X axis data" in the divided operation "B02_No1" of the operation pattern "B02_large gimmick" is extracted.

[0339] In the control command management data D3, the management data for each operation part describes the information of the "part name" of that operation part. Thereby, the CPU 41a can specify the management data of the corresponding operation part from the control command management data D3 based on the information of the "part name" described in the management data for each divided operation shown in FIG. 31.

[0340] In the control command management data D3, for the control command management data for each operation part, source code including a control command Cd for realizing the operation of the movable body accessory 50 as the operation part is described. The CPU 41a can transmit a control command Cd for realizing the operation of the movable body accessory 50 as the operation part to the motor drive control unit 51 by performing processing according to the source code.

[0341] FIG. 33 shows an example of a work screen Gs for defining operation parts. In the present embodiment, the developer defines operation parts using an application program for defining operation parts (hereinafter referred to as "operation part definition application") installed in the computer device 100 shown in FIG. 29. FIG. 33 illustrates a work screen Gs displayed by this operation part definition application.

[0342] On the work screen Gs, it is possible to define the operation for each operation pattern of the movable body accessory 50 using a flowchart-like UI (User Interface) shown on the left side in the figure. There are three types of boxes that can be used in the flowchart: boxes FS1, FS2, and FS3 illustrated in the figure. Box FS1 is a box for determining whether to use a position sensor for the axis to be defined for operation. Box FS2 is a box for defining the operation as an operation part. Box FS3 is a box for defining a standby operation such as the aforementioned "B01_No1_wait".

[0343] When box FS2 in the flowchart is selected, the operation of the operation part can be defined in the definition area Ad shown on the right side of the screen. As shown in the figure, the definition area Ad is provided with a target axis selection area Ar1 and a setting input area Ar2. The definition area Ad is provided with operation parts p1, p2, and p3. By these operation parts p1, p2, and p3, the rotation direction of the actuator motor, the above-described operation mode (positioning operation mode / sensor input stop mode), and the acceleration / deceleration control mode (for example, linear acceleration / deceleration control mode / S-curve control mode) can be selectively set. Fig. 33 shows a display example of the definition area Ad when the positioning operation mode is selected as the operation mode by the operation part p2.

[0344] The target axis selection area Ar1 is provided with an operation part for selecting which axis of the X-axis to U-axis the operation is defined for. As described above, for the moving parts, the operation of multiple axes can be defined. After selecting one box FS2, by performing the axis selection operation in the target axis selection area Ar1, for each axis, the operation definition can be performed by the input operation to the setting input area Ar2 described below.

[0345] The setting input area Ar2 is provided with an FL speed input box b2, an acceleration period input box b3, an HL speed input box b4, an output pulse number input box b5, and a deceleration period input box b6. The FL speed input box b2 is a box for inputting the above-described FL speed (initial speed, stop speed). The acceleration period input box b3 is a box for inputting the acceleration period, that is, the transition period from the initial speed to the above-described HL speed (operation speed). The HL speed input box b4 is a box for inputting the HL speed. Also, the output pulse number input box b5 is a box for inputting the above-described output pulse number (target movement amount of the movable body actuator 50). The deceleration period input box b6 is a box for inputting the deceleration period, that is, the transition period from the HL speed to the FL speed (stop speed).

[0346] By specifying the FL speed, acceleration period, HL speed, number of output pulses, and deceleration period through input operations on these FL speed input box b2, acceleration period input box b3, HL speed input box b4, output pulse number input box b5, and deceleration period input box b6, a predetermined actuator motor operation (operation of the movable body actuator 50) in the positioning operation mode can be defined. Although not shown in the figure, when the sensor input stop mode is selected, the setting input area Ar2 may simply display a UI that enables the specification of at least the FL speed, acceleration period, and HL speed.

[0347] Here, a comment input box b7 is provided in the definition area Ad. In this example, it is possible to specify the aforementioned "part name" by inputting into this comment input box b7. That is, the text information input into this comment input box b7 is associated as the "part name" information for the operation part defined by the input operation to the setting input area Ar2.

[0348] In the definition area Ad, when the execution button Bt connects the computer device 100 and the motor drive control unit 51 (in a state where a motor driver with an actuator motor connected is connected) in the development environment, it is a button for instructing the output of the control command Cd corresponding to the defined operation part to the motor drive control unit 51. By providing this execution button Bt, the developer can perform the operation part definition work while confirming the actual operation of the movable body actuator 50.

[0349] Also, in the definition area Ad, the label name input box b1 is a box for inputting the label name for the operation pattern in which the flowchart is displayed on the work screen Gs. Also, the message input b8 is a box for inputting a management message left by the developer for the defined operation part when desired.

[0350] The operation part definition application has a function of generating control command management data D3 described in the previous Figure 32 for the operation parts defined through the operation screen Gs as described above. The operation part definition application can generate control commands Cd such as RFL commands, RFH commands, and RUR commands necessary to realize the defined operations for each operation part based on values such as the FL speed, acceleration period, and HL speed specified by the operation on the above-described definition area Ad. In the positioning operation mode, an RDP command indicating the slowdown point is issued. The slowdown point (the remaining number of pulses at which deceleration starts) is automatically determined if the number of output pulses (b5) and the deceleration period (b6) are specified (because it is defined to drop from the HL speed to the FL speed during deceleration).

[0351] After the operation part definition application generates the necessary control commands Cd for each operation part as described above, it generates source code for causing the CPU 41a to execute the transmission process of the control commands Cd for each operation part. Then, by associating the information on the part names input in the above-described comment input box b7 with the generated source code for each operation part, the control command management data D3 is generated. The developer stores the control command management data D3 generated by the function of such an operation part definition application in the ROM 41b of the production control board 41.

[0352] The function of the operation part definition application as described above can significantly reduce the workload of the developer required to realize the movable object prop control as an embodiment.

[0353] [6.4 Movable Object Prop Control Process as an Embodiment] (6.4.1 Process Flow) Subsequently, the process related to the movable object prop control as an embodiment executed by the CPU 41a will be described. The control of the movable object device 50 is mainly realized by the movable object device operation update process in step S603 and the SOL·MOT output process in step S604 in the effect control side timer interrupt process shown in FIG. 24.

[0354] In the movable object device operation update process of step S603 in FIG. 24, the CPU 41a selects one operation pattern from the accessory sub-scenario data D1 shown in FIG. 30 as the production scenario progresses. The selection of one operation pattern from the accessory sub-scenario data D1 is based on the production scenario data (main scenario data), which is not shown in the figure, and the aforementioned production scenario timer.

[0355] In step S603, when one operation pattern is selected from the accessory sub-scenario data D1, the CPU 41a specifies the management data of the section operation indicated by the identification information (such as "excitation ON", "B01_No1", etc.) of the first line in the management data of the selected operation pattern (that is, the first section operation) from the management data for each section operation in the section operation management data D2 (see FIG. 31). Then, the process according to the description of the first line in the specified management data of the section operation is performed. For example, if the first line is a line with "operation type" = "drive control unit operation", the name information (such as "[C44_201_XY_TAMA_B01]{ball}TY106_pre-change △○×□ ball gimmick notice_combination No1_forward XY axis data", etc.) described in "part name" in this line is acquired. In step S603, at the next timer interrupt timing after the timer interrupt timing when an operation pattern is selected from the accessory sub-scenario data D1, the CPU 41a performs a process according to the information of "operation type" of the target line in the section operation management data D2. If it is a line with "operation type" = "drive control unit operation", the process of acquiring the name information described in "part name" in this line is performed. Also, if it is the line where "Operation Type" = "Waiting for Drive Control Unit Operation to End", the value described in the "Step" of that line is set in the "Scheduled Stop Time Timer". This Scheduled Stop Time Timer is a timer that is decremented every timer interrupt, and "0" indicates the arrival of the scheduled stop time. In step S706 of FIG. 34 described later, by determining whether this Scheduled Stop Time Timer is less than 0, it is determined whether the scheduled stop time has elapsed (that is, the operation end confirmation process described above) is performed. Here, as described above, for the operation parts, the operation of multiple axes may be defined. In that case, in the divided operation management data D2, lines where "Operation Type" = "Waiting for Drive Control Unit Operation to End" are continuously provided. When the lines where "Operation Type" = "Waiting for Drive Control Unit Operation to End" are continuously provided in this way, as the process of step S603, the CPU 41a sets the value of the Scheduled Stop Time Timer for the corresponding axis based on the values of "Step" of each of those continuous lines.

[0356] Also, when the process for the first divided operation in the selected one operation pattern is completed and the process for the second and subsequent divided operations is started, the CPU 41a performs the following process as the process of step S603. That is, when the identified divided operation is a divided operation as a waiting operation such as "B01_No1_wait" and the management data of the divided operation has only the line where "Operation Type" = "Waiting", the CPU 41a, as the process of step S603, determines whether the waiting time indicated by the value of "Step" of that line has elapsed at each interrupt timing. Then, at the step S603 of the interrupt timing when it is determined that the waiting time has elapsed, the CPU 41a starts the process using the divided operation management data D2 for the next divided operation in the selected one operation pattern. That is, the process for the second and subsequent divided operations described here is started.

[0357] Also, when the identified sectional operation is a sectional operation as an operation part such as "B01_No2", the CPU 41a performs the same processing as the processing for the first sectional operation described above. That is, it performs the processing of acquiring the name information described in the "part name", and the processing of setting the value of "step" in the row where "operation type" = "waiting for the drive control unit operation to end" to the stop scheduled time timer.

[0358] When the CPU 41a has completed the processing based on the sectional operation management data D2 as described above for all the sectional operations included in one operation pattern selected from the accessory sub-scenario data D1, as the processing of step S603, it performs the processing of determining whether a new operation pattern has been selected based on the production scenario data and the production scenario timer at each interrupt timing. As a result of performing such determination at each interrupt timing, if it is determined that a new operation pattern has been selected, the CPU 41a, as the processing of step S603 at the subsequent timer interrupt timing, performs the same processing as the processing described above based on the sectional operation management data D2 for the newly selected operation pattern.

[0359] FIG. 34 is a flowchart showing the SOL·MOT output processing of step S604 in the production control side timer interrupt processing. The processing shown in this FIG. 34 is not executed when the selected sectional operation is a standby operation such as "B01_No1_wait", and is executed corresponding to the case where the selected sectional operation is an operation as an operation part such as "B01_No1" or "B01_No2". Also, when the operation part defines the operations of a plurality of axes, the processing shown in FIG. 34 is executed for each axis.

[0360] In the SOL·MOT output processing of step S604, the CPU 41a first performs the processing of acquiring the value of the drive state register in step S701. That is, it makes an inquiry about the drive status value SRUN for the target axis to the motor drive control unit 51 and acquires the drive status value SRUN.

[0361] In step S702 following step S701, the CPU 41a determines whether or not it is in the drive stop state. That is, in this example, it determines whether or not the acquired drive status value SRUN is "0".

[0362] In step S702, if it is determined that it is in the drive stop state, the CPU 41a proceeds to step S703 and gives an instruction to the motor drive control unit 51 to perform register initialization processing, that is, to initialize the registers of the target axis in the motor drive control unit 51, and performs reception / transmission permission processing in the subsequent step S704. That is, it performs processing to permit data reception from the motor drive control unit 51 and data transmission to the motor drive control unit 51.

[0363] Then, in step S705 following step S704, the CPU 41a performs control command transmission processing. As understood from the previous description, the selected section operation is an operation as an operation part, and the motor drive control unit 51 is in the drive stop state (step S702: Yes), that is, in the state immediately before the start of the operation as the operation part, in the movable body device operation update processing of step S603, name information corresponding to the operation part is specified from the section operation management data D2. In the control command transmission processing of step S705, based on the name information specified in this way, the corresponding source code is specified from the control command management data D3, and a control command Cd for realizing the operation as the operation part is transmitted to the motor drive control unit 51 according to the specified source code.

[0364] In response to having executed the control command transmission processing of step S705, the CPU 41a advances the processing to step S708 and performs reception / transmission prohibition processing, that is, processing to prohibit data reception from the motor drive control unit 51 and data transmission to the motor drive control unit 51, and ends the SOL·MOT output processing of step S604.

[0365] Also, if the CPU 41a determines in the previous step S702 that it is not in the drive stop state, it proceeds to step S706 to determine whether the scheduled stop time has elapsed. Specifically, it determines whether the value of the aforementioned scheduled stop time timer is less than "0".

[0366] In step S706, if it is determined that the scheduled stop time has not elapsed, the CPU 41a ends the SOL·MOT output process of step S604.

[0367] On the other hand, in step S706, if it is determined that the scheduled stop time has elapsed, the CPU 41a proceeds to step S707 and executes the scenario end process. That is, it performs a process of forcibly stopping the operation of the movable body device 50 defined in the currently executing sub-scenario (operation pattern). Thereby, in the event that some abnormality occurs in the motor drive control unit 51 and the operation in progress does not end within the scheduled time, as a fail-safe process, it is possible to realize the forced stop of the operation. Since the motor drive control unit 51 used in this embodiment does not have a fail-safe function, it is to realize fail-safe by performing timeout monitoring through the processing of the CPU 41a.

[0368] When the CPU 41a performs the scenario end process of step S707, it performs the reception·transmission prohibition process of step S708 described above and ends the SOL·MOT output process of step S604.

[0369] Regarding the operation parts for which the operation in the sensor input stop mode is defined, it is also conceivable not to provide a row with the operation type = waiting for the end of the drive control unit operation as exemplified in FIG. 31 and not to perform the determination process of step S706.

[0370] Here, as described above, in this embodiment, when the selected section operation is an operation as an operation part, in the processes of steps S701 and S702, every time a timer interrupt occurs, an inquiry process of the drive control status is performed on the motor drive control unit 51 to determine whether or not the operation of the device as the operation part has been completed. Then, by the process of step S705, after it is determined that the operation of the device as the operation part has been completed, the control command output process for the next device operation is performed.

[0371] Thereby, it is possible to prevent the next control command Cd from being erroneously output before the operation as the operation part is completed, and appropriate device operation control can be realized.

[0372] (6.4.2 Regarding Microstep Drive) As described above, in the conventional device motor control, since the CPU 41a outputs control data to the motor driver at a cycle of 1 ms, it was substantially impossible to realize microstep drive in terms of operation speed. In this embodiment, the configuration in which the CPU 41a directly outputs control data to the motor driver as in the conventional case is not adopted. Instead, as the motor drive control unit 51 and the motor driver group 52, those corresponding to microstep drive are used, so that the device motor can be driven in the microstep drive mode (that is, the movable body device 50 can be moved more smoothly).

[0373] However, when the device motor is driven in microstep mode, it becomes indefinite at which excitation phase state (electrical angle) the motor operation (rotation) ends, and the motor operation may end in an intermediate excitation phase state between the reference excitation phases (reference step positions). If de-excitation is applied in that state, there is a risk that the motor cannot be properly stopped and held. Specifically, the excitation stop is performed by switching the drive mode to the two-phase excitation drive mode. However, the electrical angle at the end of the microstep drive does not necessarily coincide with any of the electrical angles in the two-phase excitation drive mode. If the excitation stop is performed in a state where the electrical angle at the end of the microstep drive does not coincide with the electrical angle in the two-phase excitation drive mode, the actuator motor may rotate significantly idly during the stop, and as a result, a large slip may occur in the movable body actuator 50 as well.

[0374] Therefore, in the present embodiment, when switching the drive mode from the microstep drive mode to the two-phase excitation drive mode, such as when stopping the actuator motor 53 after driving it in the microstep drive mode, a technique is adopted in which the electrical angle is controlled so that the amount of idling of the actuator motor is suppressed.

[0375] Hereinafter, specific examples will be described. FIG. 35 and FIG. 36 are explanatory diagrams of the electrical angle control when switching from the microstep drive mode to the two-phase excitation drive mode. In FIGS. 35A and 36A, the electrical angles in the microstep drive mode are shown on a graph with the horizontal axis = A-phase current (%), and the vertical axis = B-phase current (%). In FIGS. 35B and 36B, the electrical angles in the two-phase excitation drive mode are shown on a graph with the horizontal axis = A-phase current (%), and the vertical axis = B-phase current (%).

[0376] For confirmation, it should be noted that in this example, the microstep drive mode is the 2W1-two-phase excitation drive mode, and as shown in each A figure, the electrical angles used are determined every 22.5 (360÷16) degrees. Hereinafter, the 16 electrical angles used in the microstep drive mode will be denoted as a to p, respectively, on the increasing side of the electrical angle with the electrical angle = 45 degrees as the reference. On the other hand, in the two-phase excitation drive mode shown in each B figure, the electrical angles used are 45 degrees, 135 degrees, 225 degrees, and 315 degrees, a total of 4. Hereinafter, the 4 electrical angles used in the two-phase excitation drive mode will be denoted as A to D, respectively, on the increasing side of the electrical angle with the electrical angle = 45 degrees as the reference.

[0377] In the microstep drive mode, since the electrical angle used is larger than that in the two-phase excitation drive mode, smooth driving of the actuator motor is enabled.

[0378] Here, FIG. 35 shows the control of the electrical angle when the rotation direction is CW. In the figure, the black thick arrow indicates the change direction of the electrical angle when the rotation direction is CW. As shown by the arrow, when the rotation direction is CW, the electrical angle changes in the increasing direction.

[0379] In the present embodiment, when switching from the microstep drive mode to the two-phase excitation drive mode when the rotation direction of the actuator motor is CW, the electrical angle is controlled as follows. That is, when the electrical angle immediately before switching from the microstep drive mode to the two-phase excitation drive mode is within the range of electrical angles a to d (range of 45 degrees to 112.5 degrees = hereinafter referred to as "first range Rg1"), the electrical angle is changed to B (135 degrees: hereinafter referred to as "first electrical angle Ag1"). Also, when the electrical angle immediately before the switching is within the range of electrical angles e to h (range of 135 degrees to 202.5 degrees = hereinafter referred to as "second range Rg2"), the electrical angle is changed to C (225 degrees: hereinafter referred to as "second electrical angle Ag2"). Further, when the electrical angle immediately before the switching is within the range of electrical angles i to l (range of 225 degrees to 292.5 degrees = hereinafter referred to as "third range Rg3"), the electrical angle is changed to D (315 degrees: hereinafter referred to as "third electrical angle Ag3"). Furthermore, when the electrical angle immediately before the switching is within the range of electrical angles m to p (range of 315 degrees to 22.5 degrees = hereinafter referred to as "fourth range Rg4"), the electrical angle is changed to C (45 degrees: hereinafter referred to as "fourth electrical angle Ag4").

[0380] Here, changing the electrical angle to a specific electrical angle when switching from the microstep drive mode to the two-phase excitation mode means starting the drive in the two-phase excitation drive mode from the specific electrical angle. In other words, the drive in the two-phase excitation drive mode is started with the combination of the value of the phase A current and the value of the phase B current corresponding to the specific electrical angle. For example, changing the electrical angle to electrical angle B when switching to the two-phase excitation mode means starting the drive in the two-phase excitation drive mode by outputting a drive current with the combination of values "phase A current = -100%, phase B current = 100%", and changing the electrical angle to electrical angle C when switching to the two-phase excitation mode means starting the drive in the two-phase excitation drive mode by outputting a drive current with the combination of values "phase A current = -100%, phase B current = -100%".

[0381] By performing electrical angle control as described with reference to FIG. 35, the change amount of the electrical angle can be suppressed within 90 degrees regardless of what the electrical angle was immediately before switching to the two-phase excitation drive mode. Therefore, it is possible to suppress the amount of idling of the actuator motor when switching from the microstep drive mode to the two-phase excitation drive mode, and it is possible to improve the position control accuracy of the movable body actuator 50.

[0382] Here, in this example, the electrical angle control when switching from the microstep drive mode to the two-phase excitation mode as described above is performed independently by the motor driver in the motor driver group 52 in response to the drive mode switching instruction from the motor drive control unit 51 described above (that is, without depending on the specific electrical angle instruction from the motor drive control unit 51). Specifically, in this example, when the motor driver receives an instruction to switch the driving mode from the microstep driving mode to the two-phase excitation driving mode from the motor drive control unit 51, it controls the electrical angle based on the rotation direction (CW / CCW) of the accessory motor and the electrical angle immediately before the switching. That is, as described above, when the rotation direction is CW, if the electrical angle immediately before the switching is within the first range Rg1, the electrical angle is controlled to the first electrical angle Ag1 (B), and if the electrical angle immediately before the switching is within the second range Rg2, the electrical angle is controlled to the second electrical angle Ag2 (C), if the electrical angle immediately before the switching is within the first range Rg3, the electrical angle is controlled to the third electrical angle Ag3 (D), and if the electrical angle immediately before the switching is within the first range Rg4, the electrical angle is controlled to the fourth electrical angle Ag4 (A). Note that the rotation direction (CW / CCW) can be identified by the DIR signal (rotation direction instruction signal) output from the rotation direction output terminal DIR (see FIG. 27) of the motor drive control unit 51.

[0383] Also, when the rotation direction is CCW, the motor driver changes the electrical angle as shown in FIG. 36 when switching from the microstep driving mode to the two-phase excitation mode. That is, when the rotation direction is CCW, if the electrical angle immediately before the switching is within the first range Rg1, the electrical angle is controlled to the third electrical angle Ag3 (D), and if the electrical angle immediately before the switching is within the fourth range Rg4, the electrical angle is controlled to the second electrical angle Ag2 (C), if the electrical angle immediately before the switching is within the third range Rg3, the electrical angle is controlled to the first electrical angle Ag1 (B), and if the electrical angle immediately before the switching is within the second range Rg2, the electrical angle is controlled to the fourth electrical angle Ag4 (A).

[0384] By controlling the electrical angle as described above, when the rotation direction = CCW, the electrical angle changes by a minimum of 90 degrees and a maximum of 157.5 degrees when switching to the two-phase excitation driving mode.

[0385] As understood from the above description, in the present embodiment, when the rotation direction of the accessory motor is in the forward direction and the reverse direction, the amount of change in the electrical angle when switching from the first excitation mode (microstep drive mode) to the second excitation mode (two-phase excitation drive mode) is different. At this time, the amount of change in the electrical angle is smaller in the forward direction < reverse direction. Also, in the present embodiment, the amount of change in the electrical angle per step in the control of the motor driver is smaller in the first excitation mode < second excitation mode.

[0386] Here, in the gaming machine 1 of this example, regarding the drive of the movable accessory 50y that is moved to the effect position by downward drive, the rotation direction = CW is assigned to the return side to the origin position (that is, upward drive). If the rotation direction = CCW is assigned to the return side to the origin position, when the movable accessory 50y stops at the origin position, the amount of change in the electrical angle becomes large (a change of up to 157.5 degrees), and there is a risk that the movable accessory 50y will shift and fall off. On the other hand, if the rotation direction = CW is assigned to the upward drive of the movable accessory 50y, the amount of change in the electrical angle when the movable accessory 50y stops at the origin position can be suppressed within 90 degrees, so that it is possible to suppress the shift and fall, which is preferable.

[0387] Note that not only the own weight of the movable accessory 50 but also some external force (for example, human force, biasing force of a spring, etc.) may be applied to the movable accessory 50. Therefore, there is a movable margin with respect to the movable direction of the movable accessory 50. When it is desired to execute a stop operation in the two-phase excitation drive mode in such a situation, regarding the drive of the movable accessory 50 that can move in a direction other than the vertical direction, it is also conceivable to assign the rotation direction = CW in the same manner.

[0388] Here, regarding the electrical angle control at the time of switching to the two-phase excitation drive mode, for example, regardless of the electrical angle immediately before the drive mode switch, it is also conceivable to control to any one of the first electrical angle Ag1 to the fourth electrical angle Ag4 in the two-phase excitation drive mode. However, in that case, the amount of change in the electrical angle at the time of drive mode switch becomes up to 360 degrees. Compared with such a case, even by the electrical angle control in the CCW direction as shown in FIG. 36, the amount of motor idling during the switching to the two-phase excitation drive mode can be suppressed, and the position control accuracy of the actuator motor 53 can be improved.

[0389] FIG. 37 shows a schematic configuration example of the motor driver 52y. Note that the configuration shown in FIG. 37 is also applicable to other motor drivers in the motor driver group 52. The motor driver 52y is provided with a total of three terminals, namely, DMODE0 terminal, DMODE1 terminal, and DMODE2 terminal, for receiving the designation of the drive mode from the motor drive control unit 51. The switching instruction of the drive mode is performed by the combination of the three values of DMODE0, DMODE1, and DMODE2, and the details will be described later.

[0390] In addition, the motor driver 52y is provided with a CW / CCW terminal for receiving the rotation direction instruction by the aforementioned DIR signal from the motor drive control unit 51, a CLK terminal for receiving the OUT signal (a pulse signal indicating the period of the drive pulse of the actuator motor 53), and an ENABLE terminal which is an input terminal of the ENABLE signal. Note that the ENABLE signal will be described later.

[0391] Furthermore, the motor driver 52y is provided with four terminals, namely, MOTyA+ terminal, MOTyA- terminal, MOTyB+ terminal, and MOTyB- terminal, as terminals for outputting the drive current to the actuator motor. The MOTyA+ terminal and the MOTyA- terminal are terminals for outputting the aforementioned A-phase current, and the MOTyB+ terminal and the MOTyB- terminal are terminals for outputting the aforementioned B-phase current.

[0392] As shown in the figure, the motor driver 52y includes a decode unit 521, a motor control circuit 522, an A-phase current output circuit 523A, and a B-phase current output circuit 523B. The decoding unit 521 decodes the input signals from the above-described DMODE0 terminal to DMODE2 terminal, CW / CCW terminal, CLK terminal, and ENABLE terminal, and outputs them to the motor control circuit 522.

[0393] Based on the control of the motor control circuit 522, the A-phase current output circuit 523A and the B-phase current output circuit 523B generate an A-phase current and a B-phase current, and output them to the corresponding servomotor via the MOTyA+ terminal and MOTyA- terminal, and the MOTyB+ terminal and MOTyB- terminal, respectively.

[0394] Based on each signal decoded by the decoding unit 521, the motor control circuit 522 controls the generation operation of the A-phase current by the A-phase current output circuit 523A and the generation operation of the B-phase current by the B-phase current output circuit 523B, thereby generating the A-phase current and the B-phase current for realizing the operation of the servomotor according to the input signals from each input terminal such as the CW / CCW terminal and the CLK terminal described above.

[0395] The motor control circuit 522 has an electrical angle detection unit 522a. The electrical angle detection unit 522a detects the electrical angle during control. In both the microstep drive mode and the two-phase excitation drive mode, the electrical angle detection unit 522a controls the electrical angle for rotating the servomotor. The electrical angle detection unit 522a shows the function of detecting the electrical angle controlled by the motor control circuit 522 itself in a blocked manner.

[0396] In this example, the electrical angle control during drive mode switching described in the previous FIGS. 35 and 36 is executed by the motor control circuit 522 in the motor driver 52y.

[0397] FIG. 38 is a flowchart showing an example of the processing procedure executed by the motor control circuit 522 to realize the electrical angle control as an embodiment. In FIG. 38, the motor control circuit 522 first determines, in step S1001, whether there is an instruction to switch from the first excitation mode to the second excitation mode. Specifically, in this example, it determines whether there is an instruction to switch from the microstep drive mode to the two-phase excitation drive mode. Note that in this example, the identification of the drive mode is made possible by the combination of H / L of the input signals from the DMODE0 terminal to the DMODE2 terminal, as will be described later.

[0398] If it is determined in step S1001 that there is no instruction to switch from the first excitation mode to the second excitation mode, the motor control circuit 522 ends the series of processes shown in FIG. 38.

[0399] On the other hand, if it is determined in step S1001 that there is an instruction to switch from the first excitation mode to the second excitation mode, the motor control circuit 522 proceeds to step S1002 and determines whether the rotation direction is CW or CCW.

[0400] If the rotation direction is CW, the motor control circuit 522 proceeds to step S1003 and branches the process according to which of the first range Rg1 to the fourth range Rg4 the electrical angle just before the switching belongs to.

[0401] That is, if the electrical angle just before the switching is within the first range Rg1, the motor control circuit 522 controls the electrical angle to the first electrical angle Ag1(B) in step S1004 and ends the series of processes shown in FIG. 38. Also, if the electrical angle just before the switching is within the second range Rg2, the motor control circuit 522 controls the electrical angle to the second electrical angle Ag2(C) in step S1005 and ends the series of processes shown in FIG. 38. If the electrical angle just before the switching is within the third range Rg3, it controls the electrical angle to the third electrical angle Ag3(D) and ends the series of processes shown in FIG. 38. Further, if the electrical angle just before the switching is within the fourth range Rg4, it controls the electrical angle to the fourth electrical angle Ag4(A) and ends the series of processes shown in FIG. 38.

[0402] Further, when it is determined in the previous step S1002 that the rotation direction is CCW, the motor control circuit 522 proceeds to step S1008 and branches the processing according to which of the first range Rg1 to the fourth range Rg4 the electrical angle immediately before the switching belongs to.

[0403] That is, when the motor control circuit 522 determines in step S1008 that the electrical angle immediately before the switching is within the first range Rg1, it controls the electrical angle to the third electrical angle Ag3(D) in step S1009 and ends the series of processes shown in FIG. 38. Also, when the motor control circuit 522 determines in step S1008 that the electrical angle immediately before the switching is within the fourth range Rg4, it controls the electrical angle to the second electrical angle Ag2(C) in step S1010 and ends the series of processes shown in FIG. 38. When it is determined in step S1008 that the electrical angle immediately before the switching is within the third range Rg3, it controls the electrical angle to the first electrical angle Ag1(B) in step S1011 and ends the series of processes shown in FIG. 38. Further, when it is determined in step S1008 that the electrical angle immediately before the switching is within the second range Rg2, it controls the electrical angle to the fourth electrical angle Ag4(A) in step S1012 and ends the series of processes shown in FIG. 38.

[0404] (6.4.3 Regarding the Use of the Pre-register) As shown in the previous FIG. 27, the motor drive control unit 51 in the present embodiment has a pre-register unit 74. The pre-register in the pre-register unit 74 is a register provided to enable setting in advance the control command Cd for realizing the subsequent operation when it is desired to execute the subsequent operation after the execution of the operation according to the control command Cd set in the register in the register unit 73. If the control command Cd is preset in the pre-register, after the operation according to the control command Cd set in the register unit 73 is completed, the control command Cd set in the pre-register is slid to the register in the register unit 73, and the next operation is started.

[0405] By using such a pre-register, it is possible to start the control of the next actuator motor operation in the motor drive control unit 51 without depending on the timer interrupt cycle (1 ms cycle in this example) of the CPU 41a, that is, without generating a 1 ms blank.

[0406] However, since the motor drive control unit 51 used in this embodiment does not have a fail-safe function, when using a pre-register, even if the immediately preceding operation set in the register unit 73 is in error, there is a disadvantage that the control of the next actuator motor operation will be executed.

[0407] Therefore, in this embodiment, basically, the actuator motor operation control that does not use a pre-register (that is, only uses the register unit 73) is adopted, and for only some series of operations, the actuator motor operation control that uses a pre-register is adopted.

[0408] Specifically, for example, for a series of operations that change the rotational speed of the actuator motor during the operation, such as a series of operations of decelerating when reaching the position sensor, the actuator motor operation control that uses a pre-register is adopted. If a method of setting the control command Cd corresponding to the operation before the speed change and the control command Cd corresponding to the operation after the speed change in the register unit 73 in a time-sharing manner is adopted, a 1 ms blank will occur during the speed change, and there is a risk that the actuator motor will go out of synchronization. For this reason, the "operation until reaching the sensor" and the "deceleration operation after reaching the sensor" are set in the register unit 73 and the pre-register unit 74, respectively. In this case, for the stop scheduled time timer described above, a value corresponding to the total time of these "operation until reaching the sensor" and "deceleration operation after reaching the sensor" is set, and the end scheduled timing of the latter operation is confirmed by the timer interrupt process (step S702).

[0409] Here, when using a pre-register, in the divided operation management data D2 shown in FIG. 31, rows of operation type = drive control unit operation are continuously provided, and information on the part name defining the operations corresponding to those rows is described. When the operation type = drive control unit operations are continuous in this way, the CPU 41a issues an instruction to the motor drive control unit 51 to set the control command Cd specified from the part name of one line (for example, the preceding line) in the register unit 73, and issues an instruction to the motor drive control unit 51 to set the control command Cd specified from the part name of the other line (for example, the following line) in the pre-register unit 74.

[0410] Also, as an example of how to use the pre-register, the following cases can be considered. Here, as a series of operations of the movable body device 50, it is assumed that 1) move to the origin (move to the position sensor), 2) push into the origin (positioning operation), and 3) stop excitation (for example, a predetermined time such as 100 ms). In this case, at the start of the operation of 1), the control command Cd for the operation of 1) is written in the register, and the control command Cd for the operation of 2) is written in the pre-register unit 47. As a result, after the operation of 1) is completed, the data in the pre-register is automatically written in the register, and the continuous operations of 1) and 2) are realized. At this time, since the operation of 3) cannot be registered initially, it is considered to perform corresponding control such as monitoring that the data in the pre-register is written in the register unit 73, and writing the control command Cd for the operation of 3) in the pre-register unit 74 after a free space occurs in the pre-register unit 74.

[0411] [6.5 Current value switching as an embodiment and countermeasures against motor malfunction at startup] FIG. 39 is a circuit block diagram showing a configuration example of the peripheral circuit of the motor drive control unit 51. Here, together with an example of the peripheral circuit configuration of the motor drive control unit 51, the effect control board 41 is also shown. Also, in FIG. 39, regarding the peripheral circuit configuration of the motor drive control unit 51, only the circuit configuration of the X axis is extracted and shown.

[0412] Here, among the terminals of the motor drive control unit 51, the pulse signal output terminal OUTx which is the output terminal of the OUT signal (OUTx signal) of the X-axis, the rotation direction output terminal DIRx which is the output terminal of the DIR signal (DIRx signal) of the X-axis, and the general-purpose input / output terminals P0x, P1x, P2x, P3x which are the general-purpose input / output terminals P0, P1, P2, P3 of the X-axis are shown.

[0413] Also, in the figure, the motor driver 52x and the actuator motor 53x respectively represent the X-axis motor driver in the motor driver group 52 and the X-axis actuator motor in the actuator motor group 53, and the position sensor 55x represents the position sensor provided for the movable body actuator 50x in the position sensor group 55.

[0414] In the motor drive control unit 51 of this example, the general-purpose input / output terminal P0 is selected as the input terminal for the positioning sensor signal, and as shown in the figure, the detection signal by the position sensor 55x is input to the general-purpose input / output terminal P0x via the buffer 91x.

[0415] The motor driver 52x has a clock (CLK) terminal to which the OUTx signal from the motor drive control unit 51 is input, and a rotation direction (CW / CCW) input terminal to which the DIRx signal is input. Also, the motor driver 52x has a total of four output terminals for the positive and negative polarities of each of the A-phase and B-phase as the output terminals for the drive current (motor drive current) for the actuator motor 53x. Also, the motor driver 52x has an ENABLE terminal to which the ENABLE signal is input, and a Vref terminal which is the input terminal for the reference voltage Vref.

[0416] When the ENABLE signal is ON, the motor driver 52x is configured to output a motor drive current with a current value corresponding to the reference voltage Vref input to the Vref terminal to the utility motor 53x. At this time, as the motor drive current, a current with a polarity corresponding to the DIRx signal input to the rotation direction input terminal is output. Also, when an OUTx signal is input to the clock terminal, the motor driver 52x outputs a motor drive current having a pulse waveform with a period corresponding to the period of the OUTx signal.

[0417] Here, the motor driver 52y, which will be described later, also has the same terminals as the motor driver 52x, and outputs a motor drive current in the same manner as the motor driver 52x according to the input ENEBLE signal, reference voltage Vref, DIR signal, and OUT signal.

[0418] Also, in the present embodiment, each motor driver in the motor driver group 52 is configured to be able to switch between at least a two-phase excitation drive mode and a microstep drive mode as the drive mode of the utility motor. As shown in the figure, the motor driver 52x has three terminals, namely, a DMODE0 terminal, a DMODE1 terminal, and a DMODE2 terminal, as drive mode terminals for receiving an instruction to switch the drive mode.

[0419] FIG. 40 is a diagram showing the correspondence between the input values to the drive mode terminals and the drive modes. As can be seen from this figure, the motor driver 52x in this example sets its own drive mode to the two-phase excitation drive mode in response to the input of DMODE0 terminal = L level, DMODE1 terminal = L level, and DMODE2 terminal = H level, and sets its own drive mode to the 2W1-two-phase excitation drive mode, which is the microstep drive mode, in response to the input of DMODE0 terminal = H level, DMODE1 terminal = L level, and DMODE2 terminal = H level.

[0420] In FIG. 39, as shown in the figure, the input signal to the DMODE1 terminal is fixed at the L level, and the input signal to the DMODE2 terminal is fixed at the H level. Therefore, in the motor driver 52x in this example, by switching the input signal level to the DMODE0 terminal between the L level and the H level, it is possible to switch between the two-phase excitation drive mode and the microstep drive mode.

[0421] When the drive mode of the accessory motor is specified by the control command Cd from the effect control board 41, the motor drive control unit 51 outputs a drive mode control signal for setting the specified drive mode to the motor driver. Specifically, the motor drive control unit 51 (command register control circuit 72) in this example generates and outputs a drive mode control signal at the L level when the two-phase excitation drive mode is instructed by the control command Cd from the effect control board 41, and generates and outputs a drive mode control signal at the H level when the microstep drive mode is instructed. In the motor drive control unit 51 of this example, this drive mode control signal is output from any one of the general-purpose input / output terminals P0 to P3 described above. Specifically, the motor drive control unit 51 of this example is set so that the general-purpose input / output terminal P1 becomes the output terminal of the drive mode control signal.

[0422] As shown in the figure, the above drive mode control signal is input to the DMODE0 terminal in the motor driver 52x from the general-purpose input / output terminal P1x of the motor drive control unit 51. Thereby, it is possible for the motor driver 52x to appropriately switch between the two-phase excitation drive mode and the microstep drive mode according to the drive mode instruction by the control command Cd.

[0423] Here, in the conventional gaming machine described with reference to FIG. 25 above, as motor drivers 52x and 52y, drivers configured to switch the motor drive current value in predetermined steps (for example, 16 steps or the like) by register setting were used. For this reason, the CPU 41a of the effect control board 41' switches the motor drive current value between a weak current (the standby current value described above: for example, about 100 mA) and a strong current (the drive current value described above: for example, about 470 mA) by performing register setting of the driver. For confirmation, it should be noted that the switching between the weak current and the strong current of the motor drive current should be performed at the drive start timing (weak current → strong current) and the drive end timing (strong current → weak current) of the accessory motor.

[0424] In the gaming machine 1 of the present embodiment, as the motor driver 52x (similarly for the motor driver 52y), a driver having no current value switching function by the above-described register setting is adopted, and it is necessary to adopt a new method for switching the motor drive current value instead of the above-described conventional method.

[0425] In the present embodiment, a configuration is adopted in which the switching of the motor drive current value is realized by using the Vref terminal provided in the motor driver 52x. Specifically, the switching of the motor drive current value is realized by using the switching circuit 92x in the figure.

[0426] As shown in the figure, for the switching circuit 92x, the output signal of the general-purpose input / output terminal P3x in the motor drive control unit 51 is input. As described above, in the present embodiment, the general-purpose input / output terminal P3 is assigned to the output of the current up / down signal CDWN, so the current up / down signal CDWN is given as an input signal to the switching circuit 92x.

[0427] The switching circuit 92x is configured as a variable voltage dividing circuit having a power supply voltage of a predetermined level (in this example, a power supply voltage of DC5V) as an input voltage, and is configured to include a resistor R1, a resistor R2, a resistor R3, and a switching element Q1 as shown in the figure. In this case, an NPN bipolar transistor is used as the switching element Q1. The collector of the switching element Q1 is connected to the DC5V power supply via the resistor R1, and the emitter is grounded via the resistor R2. Also, a resistor R3 is connected in parallel to the DC5V power supply, and the end of the resistor R3 opposite to the connection point with the DC5V power supply is connected to the connection point between the emitter of the switching element Q1 and the resistor R2. The base of the switching element Q1 is connected to the general-purpose input / output terminal P3x of the motor drive control unit 51. Thereby, the current up / down signal CDWN is given as the ON / OFF control signal of the switching element Q1. In the switching circuit 92x, the connection point between the resistor R3 and the resistor R2 becomes the voltage-dividing output point, and this voltage-dividing output point is connected to the Vref terminal in the motor driver 52x. That is, the voltage voltage-divided and output by the switching circuit 92x is given as the reference voltage Vref of the motor driver 52x.

[0428] In the switching circuit 92x with the above configuration, when the current up / down signal CDWN is at the L level (OFF level), the switching element Q1 is turned OFF. Therefore, the voltage Vd at the voltage-dividing output point is expressed as "Vd = R3 / (R3 + R2) × 5V". On the other hand, when the current up / down signal CDWN is at the H level (ON level), since the switching element Q1 is turned ON, the voltage at the voltage-dividing output point becomes the voltage based on the combined resistance value of R1 and R3 and R2. Here, the combined resistance value of R1 and R3 is "R1 × R3 / (R1 + R3)". Let this combined resistance value be R0. Then, the voltage Vd when the current up / down signal CDWN is at the H level is expressed as "R0 / (R0 + R2) × 5V". At this time, since R3 > R0, the voltage Vd increases for the switching from the L level to the H level of the current up / down signal CDWN and decreases for the switching from the H level to the L level.

[0429] As described above, since the motor driver 52x is configured to output a motor drive current having a current value corresponding to the reference voltage Vref input to the Vref terminal to the accessory motor 53x, due to the operation of the switching circuit 92x as described above, when the current up / down signal CDWN is at the L level, the motor driver 52x outputs a weak current as the motor drive current, and when the current up / down signal CDWN is at the H level, it can output a strong current as the motor drive current.

[0430] As described above, in this embodiment, the switching between the weak current and the strong current of the motor drive current is performed by the control of the switching circuit 92x by the motor drive control unit 51. That is, in realizing the switching between the weak current and the strong current, it is not necessary for the CPU 41a of the effect control board 41' to directly issue an instruction to switch the drive current value to the motor driver as in the conventional case. Therefore, it is possible to reduce the processing load of the CPU 41a related to the control of the movable body accessory 50 and the load of the software creation work related to the control.

[0431] FIG. 41 illustrates the state of switching of the motor drive current value according to the current up / down signal CDWN. As described with reference to FIG. 28 above, at the timing (CSTA) when the drive start of the accessory motor 53x is instructed by the start command from the effect control board 41, the current up / down signal CDWN changes from the OFF level (L level) to the ON level (H level). Due to the operation of the switching circuit 92x described above, in response to such a change of the current up / down signal CDWN from the OFF level to the ON level, the current value of the motor drive current from the motor driver 52x to the accessory motor 53x gradually changes from the current value as the weak current to the current value as the strong current. At this time, as described above, by providing the current up period, a sufficient period for increasing the motor drive current value to the strong current (drive-time current value) is ensured.

[0432] Also, the current up-down signal CDWN changes from the ON level to the OFF level in response to the elapse of a predetermined current down period from the stop timing of the pulse output of the OUTx signal. In response to such a change in the ON level → OFF level of the current up-down signal CDWN, due to the operation of the switching circuit 92x described above, the current value of the motor drive current from the motor driver 52x to the accessory motor 53x gradually decreases from the current value as the strong current to the current value as the weak current. As described above, by providing the current down period, it is possible to ensure the time for the accessory motor 53x to surely stop.

[0433] Here, in the above, as an example, the current up-down signal CDWN is used as the signal input to the switching circuit 92x for switching between the weak current and the strong current. However, for this signal, as long as it is a signal whose value is inverted at the start timing and the end timing of the drive of the accessory motor, other signals can also be used. The "timing" in the "start timing" and "end timing" mentioned here does not refer only to the exact "time point", but is a concept with a certain time width.

[0434] In FIG. 39, the ENABLE control circuit 93x controls the level of the ENABLE signal input to the motor driver 52x.

[0435] Here, if the motor drive control unit 51 is configured to ON / OFF control the ENABLE signal of the motor driver 52x, the level of the ENABLE signal becomes indeterminate when the motor drive control unit 51 is started, which may cause malfunction of the accessory motor 53x. Therefore, in the present embodiment, an ENABLE control circuit 93x is provided to take countermeasures.

[0436] As shown in the figure, the ENABLE control circuit 93x is configured to include a resistor R4, a resistor R5, a resistor R6, and a switching element Q2. In this example, an N-type FET (electrolytic effect transistor) is used as the switching element Q2. The gate of the switching element Q2 is connected to the general-purpose input / output terminal P2x of the motor drive control unit 51. Also, the gate of the switching element Q2 is connected to a power supply voltage of a predetermined level (DC5V in this example) via the resistor R4. The drain of the switching element Q2 is connected to a power supply voltage of a predetermined level (DC5V in this example) via the resistor R5, and the source is grounded. The connection point between the drain of the switching element Q2 and the resistor R5 is connected to the ENABLE terminal in the motor driver 52x via the resistor R6.

[0437] In this embodiment, the motor drive control unit 51 can set, by the control command Cd, a fixed H-level output or a fixed L-level (grounded) output as the signal assignment of the general-purpose input / output terminals P0 to P3. In this example, when the motor drive control unit 51 is activated, the effect control board 41 performs a process of setting the general-purpose input / output terminal P2x to a fixed L-level output with respect to the command register control circuit 72 of the X-axis circuit by the control command Cd. As a result, the motor drive control unit 51 is configured to fix (ground) the general-purpose input / output terminal P2x at the L-level in response to activation.

[0438] When the motor drive control unit 51 is in a state before the start of activation or in a state immediately after the start of activation of the motor drive control unit 51, and the signal level of the general-purpose input / output terminal P2x is not at the L-level (ground level), in the ENABLE control circuit 93x, since the gate of the switching element Q2 is connected to the power supply voltage, the switching element Q2 is in the ON state. Therefore, an L-level (OFF-level) signal is output as the ENABLE signal. On the other hand, when the signal level of the general-purpose input / output terminal P2x becomes the L-level with the activation of the motor drive control unit 51, in the ENABLE control circuit 93x, the switching element Q2 is turned OFF, and accordingly, an H-level (ON-level) signal is output as the ENABLE signal.

[0439] In this way, it is possible to prevent the ENABLE signal from being turned on before the motor drive control unit 51 starts. That is, it is possible to prevent the malfunction of the accessory motor 53x caused by the level of the ENABLE signal being indeterminate when the motor drive control unit 51 starts.

[0440] [6.6 Countermeasures against accessory dropping during startup] As described with reference to FIGS. 3 and 4 above, in the present embodiment, the movable body accessory 50y on the Y-axis is a movable body accessory 50 that is driven downward from the shielding position. In other words, it is a movable body accessory 50 having a movable range below the shielding position.

[0441] For the movable body accessory 50 whose movable range is below the shielding position in this way, when the drive of the accessory motor performed last before the start of the motor drive control unit 51 was by the microstep drive mode, there is a risk of dropping due to its own weight when the motor drive control unit 51 starts thereafter. Specifically, when the motor drive control unit 51 starts in this case, when the ENABLE signal is turned on, a motor drive current with a weak current is output from the motor driver to the accessory motor. However, if the last drive mode before startup is the microstep drive mode, it becomes indeterminate in which excitation phase state the motor operation ended. If the motor operation ended in an intermediate excitation phase state between the reference excitation phases (reference step positions), a sufficient stop holding force cannot be obtained even when a motor drive current with a weak current is applied. As a result, there is a risk that the movable body accessory 50 will drop due to its own weight.

[0442] Therefore, in the present embodiment, a startup mode control circuit 94 as shown in FIG. 42 is provided in the Y-axis motor control system. As can be seen with reference to FIG. 42, in this example, also in the Y-axis motor control system, the detection signal of the position sensor (55y) is input to the general-purpose input / output terminal P0 (P0y) via the buffer 91 (91y). Also, a switching circuit 92y having the same circuit configuration as the above-described switching circuit 92x is provided to realize switching of the motor drive current value (weak current / strong current switching) according to the current up / down signal CDWN output from the general-purpose input / output terminal P3x. Furthermore, by providing an ENABLE control circuit 93y having the same circuit configuration as the ENABLE control circuit 93x, malfunction of the accessory motor 53y at startup is prevented in the same manner as in the case of the X-axis.

[0443] As shown in the figure, the startup mode control circuit 94 has the same circuit configuration as the ENABLE control circuits 92 (92x and 92y). The general-purpose input / output terminal P1y of the motor drive control unit 51 is connected to the gate of the switching element Q2 in the startup mode control circuit 94. In this example, in the motor drive control unit 51, for the Y-axis as well, the output of the drive mode control signal is assigned to the general-purpose input / output terminal P1 described above. Therefore, when the motor drive control unit 51 is started, a drive mode control signal is output from the general-purpose input / output terminal P1y to the gate of the switching element Q2 in the startup mode control circuit 94. However, it is assumed that for the drive mode control signal of the Y-axis, two-phase excitation drive mode = H level, microstep drive mode = L level.

[0444] Also, in the startup mode control circuit 94, the connection point between the drain of the switching element Q2 and the resistor R5 is connected to the DMODE0 terminal of the motor driver 52y via the resistor R6.

[0445] In this example, when the last drive of the accessory motor 53y was by the microstep drive mode, an L-level drive mode control signal is output in response to the startup of the motor drive control unit 51, but the level of the drive mode control signal is also indeterminate during the period immediately after the startup of the motor drive control unit 51.

[0446] In the startup mode control circuit 94, when the motor drive control unit 51 is in the state before the start of startup or immediately after the start of startup of the motor drive control unit 51, and the signal level of the general-purpose input / output terminal P1y is not at the L level (ground level), since the gate of the switching element Q2 is connected to the power supply voltage, the switching element Q2 is turned on, and thus the output signal to the DMODE0 terminal becomes the L level (OFF level). From the previous FIG. 40, if the input signal level to the DMODE0 terminal is at the L level in this way, the motor driver 52y will be instructed to operate in the two-phase excitation drive mode as the drive mode. Therefore, it is possible to prevent the movable body 50y from dropping due to its own weight when the motor drive control unit 51 starts up.

[0447] Here, when the drive mode control signal output from the general-purpose input / output terminal P1y is at the H level corresponding to the case of the two-phase excitation drive mode, in the startup mode control circuit 94, the switching element Q2 is turned on, and an L-level signal is input to the DMODE0 terminal. Therefore, the motor driver 52y is instructed to operate in the two-phase excitation drive mode. On the other hand, when the drive mode control signal output from the general-purpose input / output terminal P1y is at the L level corresponding to the case of the microstep drive mode, in the startup mode control circuit 94, the switching element Q2 is turned off, and an H-level signal is input to the DMODE0 terminal, and the motor driver 52y is instructed to operate in the microstep drive mode. In this way, after the motor drive control unit 51 starts up, an appropriate drive mode according to the drive mode control signal is instructed to the motor driver 52y.

[0448] [Regarding countermeasures against backlash] In the gaming machine 1 of the embodiment, the driving of the movable accessory 50 by the accessory motors in the accessory motor group 53 is performed via a power transmission mechanism 58 having a plurality of gears Gr as exemplified in FIG. 43. In this case, the power from the accessory motor is transmitted to the movable accessory 50 via the plurality of gears Gr. Generally, in this type of power transmission mechanism 100, a gap called backlash (or backlash: hereinafter referred to as "backlash BL") is provided at the meshing portion Pb between the gears Gr (see the enlarged view of the meshing portion Pb in the figure). For confirmation, the backlash BL means a gap (play) intentionally provided in the movement direction when a pair of gears Gr are meshing and moving.

[0449] If such a play as the backlash BL is provided, a time lag will occur from the start of driving of the accessory motor until power is actually transmitted to the movable accessory 50 side. If the amount of backlash BL at the start of driving of the accessory motor is constant, the above time lag will also be constant, so the amount of operation delay of the movable accessory 50 will also be constant. However, in reality, since the amount of backlash BL at the start of driving is indefinite, the amount of operation delay of the movable accessory 50 will vary, and there is a risk that the position control accuracy of the movable accessory 50 will decrease and the accuracy of the effect will decrease. Here, a countermeasure method against the decrease in the accuracy of the effect caused by such backlash BL is proposed.

[0450] Hereinafter, the amount of backlash BL will be referred to as the "backlash amount". In FIG. 43, as an example for explanation, the case where the number of gears Gr included in the power transmission mechanism 58 is two is exemplified, so the backlash amount was the amount of backlash BL at one meshing portion Pb between those two gears Gr. However, as exemplified in FIG. 44, the power transmission mechanism 58 may be configured to have 3 or more gears Gr. In this case, the backlash amount is the total value of the amounts of backlash BL at each of the 2 or more meshing portions Pb between the respective gears Gr of those 3 or more gears Gr.

[0451] First, with reference to FIG. 45, let's specifically consider the decrease in the position control accuracy of the movable member 50 due to the backlash BL. FIG. 45 shows the movement of the movable member 50 when it is driven from the origin position to the operating position (the detected position by the position sensor 55) by a graph with the horizontal axis = distance and the vertical axis = speed. In the figure, the thick solid line indicates the movement of the movable member 50 when the backlash amount at the start of driving the member motor is minimum, and the thick dashed line indicates the movement of the movable member 50 when the backlash amount is maximum.

[0452] Here, as the driving method of the member motor, it is assumed that the rotational speed is increased to a predetermined target speed for a certain period from the start of driving, and then the target speed is maintained until the target timing, and further, depending on the detection of the movable member 50 by the corresponding position sensor in the position sensor group 55, field weakening is performed.

[0453] The initial speed of the movable member 50 when the backlash amount is maximum is faster compared to when the backlash amount is minimum because the idling period of the member motor due to the backlash BL is longer than that when the backlash amount is minimum. Due to the fact that the initial speed is fast in this way, the maximum speed reaching point (the position where the speed reaches the above-mentioned target speed) of the movable member 50 when the backlash amount is maximum is ahead of that when the backlash amount is minimum. That is, when the backlash amount at the start of driving the member motor is different, there is a difference in the time until the movable member 50 reaches the predetermined target speed.

[0454] Note that here we focused on the timing of reaching the predetermined target speed, but the fact that there is a difference in the time until the movable member 50 reaches the target speed as described above means that there is also a difference in the time until the movable member 50 reaches the predetermined position.

[0455] In FIG. 45B, the difference in the movement of the movable member accessory 50, taking into account not only the difference in the backlash amount at the start of driving but also the difference in the position of the movable member accessory 50 at the start of driving, is shown by the same graph as in FIG. 45A. Specifically, in FIG. 45B, the movement of the movable member accessory 50 when the movable member accessory 50 is located at the origin position and the backlash amount is minimized at the start of driving is shown by a thick solid line, and the movement of the movable member accessory 50 when the movable member accessory 50 is located at a position deeper than the origin position and the backlash amount is maximized at the start of driving is shown by a thick dashed line. The time difference until the movable member accessory 50 reaches a predetermined target speed becomes larger than in the case of FIG. 45A as the initial position of the movable member accessory 50 is deeper.

[0456] Here, in the gaming machine 1 of the present embodiment, as an effect using the movable member accessory 50, it is assumed that an effect having synchronization with the display image of the liquid crystal display device 20 is performed. In the present embodiment, on such a premise, as a countermeasure against backlash, the gaming machine 1 is configured as follows as a countermeasure. That is, when the movable member accessory 50 is driven from a state where the backlash amount (play amount of the gear Gr) in the power transmission mechanism 58 is maximum and when the movable member accessory 50 is driven from a state where the backlash amount is minimum, the time difference (hereinafter referred to as "time difference Dt") until the movable member accessory 50 reaches a predetermined target speed is less than one frame period of the image displayed on the liquid crystal display device 20, and the gaming machine 1 is configured.

[0457] By configuring the gaming machine 1 as described above, as shown in FIG. 46A, it becomes possible to make the target speed reach timing of the movable member accessory 50 at the minimum and maximum backlash amounts within the display period of the same frame image, and it becomes possible to make the delay of the movable object effect caused by backlash less noticeable. Therefore, when performing a movable object effect synchronized with an image, it is possible to prevent a decrease in the accuracy of the effect.
