The plurality of speakers 17 allows so-called stereophonic sound reproduction or multi-channel sound reproduction for sounds related to the performance.

[0020] Next, the configuration of the game board 5 will be described with reference to Fig. 3. Fig. 3 is a front view of the game board 5. The illustrated game board 5 has a ball guide rail 18 attached in a ring shape as a board surface partition member to guide the launched game balls, and the approximately circular area surrounded by this ball guide rail 18 is the game area 19, while 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] A liquid crystal display device (LCD) 20 is provided in the approximate center of this game area 19. The liquid crystal display device 20 is capable of performing variable display operations (variable display and stationary display) of multiple types of decorative patterns (for example, a left pattern (corresponding to the left display area), a middle pattern (corresponding to the middle display area), and a right pattern (corresponding to the right display area)) using numbers, characters, symbols, etc. independently in, for example, three (left, middle, right) display areas (variable pattern display areas). This liquid crystal display device 20 displays various effects as images in addition to the variable display operation of decorative symbols under the control of an effect control board 41 described later.

[0022] In addition, a center ornament 21 is provided in the center of the game area 19, surrounding the display surface of the liquid crystal display device 20 at a distance. The center ornament 21 is provided along the front side of the game board 5, and protects the display surface of the liquid crystal display device 20 from collision with game balls, and also functions as a flow path distribution means that enables the flow path of game balls to be distributed to the left or right depending on the strength or stroke length of the game balls. In this embodiment, the center ornament 21 is placed approximately in the center of the play area 19, dividing the play area 19 into a left play area 19a and a right play area 19b on the left and right sides. A game ball launched by the launching device 44 with a launch strength less than a predetermined value flows down the left play area 19a, and a game ball launched with a launch strength equal to or greater than the predetermined value flows down the right play area 19b.

[0023] The non-play area at the bottom of the game board 5 is a display area for various functions, and is provided with a special symbol display device 22a and a special symbol display device 22b using dot displays. The various function display sections including the special symbol display devices 22a and 22b are shown enlarged in FIG.

[0024] The special symbol display devices 22a and 22b are configured to execute a special symbol variable display game by varying the display of "special symbols" represented by dot displays. The liquid crystal display device 20 displays decorative symbols in a variable manner in synchronization with the variable display of special symbols by the special symbol display devices 22a and 22b, and executes a decorative symbol variable display game together with various preview effects (effect images).

[0025] The various function display section also includes a composite display device 22c, which is made up of a dot display device similar to the special symbol display devices 22a and 22b. It is called a composite because it is a reserved / time-saving / high-probability composite display device (hereinafter simply referred to as a "composite display device") that has five display functions: displaying the first special symbol (hereinafter the first special symbol will be referred to as "special symbol 1" and sometimes abbreviated as "special symbol 1"), the second special symbol (hereinafter the second special symbol will be referred to as "special symbol 2" and sometimes abbreviated as "special symbol 2"), the number of reserved balls for normal symbols, and notifying the status during the time-saving state and the high-probability state.

[0026] The various function display section is also provided with a composite display device 22d, which is also made up of dot displays. In this composite display device 22d, a round number display is performed to notify the specified number of rounds (maximum number of rounds) related to a big win by combining the on / off states of the four LEDs. In addition, in the composite display device 22d, a normal symbol variable display game is executed by a variable display operation of a normal symbol represented by one LED as a normal symbol display. The composite display device 22d also has three LEDs that indicate a right-hit display, which indicates that it is more advantageous for the player to shoot the game ball toward the right game area 19b than to shoot the game ball toward the left game area 19a.

[0027] A first start hole 23 is provided in the center of the game board 5 and below the liquid crystal display device 20. Inside the first start hole 23, a first start hole detection sensor 23a (see FIG. 4) is provided to detect the passage of a game ball. Further, a second starting hole 24 is provided in the right game area 19b, and a second starting hole detection sensor 24a (see FIG. 3) that detects the passage of a game ball is provided inside the second starting hole 24.

[0028] The first start opening 23 is a winning opening related to the starting conditions for the variable display operation of the special symbol 1 in the special symbol display device 22a, and is configured as a fixed start opening without a start opening opening opening means (means for opening or enlarging the start opening). In this embodiment, due to the action of a game ball fall direction changing member (for example, a game nail, a windmill, a center ornament 21, etc.) in the game area 19, the first start opening 23 is configured so that game balls rolling in the left game area 19a can easily enter, but game balls rolling in the right game area 19b cannot easily enter.

[0029] The second starting port 24 is a winning port related to the starting conditions for the variable display operation of the special pattern 2 in the special pattern display device 22b, and is configured as a variable starting port whose opening and closing is controlled by the ordinary electric device 25. The normal electric device 25 is controlled to an open state that allows game balls to enter the second starting hole 24, and a closed state that makes it difficult or impossible for game balls to enter the second starting hole 24. In this embodiment, the second starting hole 24 is provided in the right playing area 19b, and only game balls that have rolled through the right playing area 19b can enter, but game balls that have rolled through the left playing area 19a may also be able to enter.

[0030] In addition, above the second starting opening 24, that is, above the middle of the right game area 19b, there is provided a normal symbol gate 26 through which game balls can pass. This normal symbol gate 26 is a winning opening related to the variable display operation of the normal symbol on the composite display device 22d, and inside it there is provided a normal symbol gate detection sensor 26a (see FIG. 4) that detects game balls passing through. In this embodiment, the normal symbol gate 26 is provided only in the right game area 19b, and only game balls that have rolled through the right game area 19b can enter. However, the present invention is not limited to this, and the normal symbol gate 26 may be provided only in the left game area 19a, or may be provided in both.

[0031] A first large prize opening 27 and a second large prize opening 28 are provided below the second starting opening 24 in the right gaming area 19b. The first large prize opening 27 and the second large prize opening 28 are positioned so that only gaming balls rolling in the right gaming area 19b can enter them. However, the first large prize opening 27 and the second large prize opening 28 may be positioned so that only gaming balls rolling in the left gaming area 19a can enter them, or they may be positioned so that gaming balls rolling in the left gaming area 19a and the right gaming area 19b can enter them. The first large prize opening 27 is controlled to open and close by a first special electric device 29. The first special electric device 29 is controlled to an open state that allows a game ball to enter the first large prize opening 27, and a closed state that makes it difficult or impossible for a game ball to enter the first large prize opening 27. The second large prize opening 28 is controlled to open and close by a second special electric device 30. The second special electric device 30 is controlled to an open state that allows game balls to enter the second large prize opening 28, and a closed state that makes it difficult or impossible for game balls to enter the second large prize opening 28. Inside the first large prize opening 27 and the second large prize opening 28, there are provided a first large prize opening detection sensor 27a and a second large prize opening detection sensor 28a (see FIG. 4) respectively, which detect the passage of gaming balls.

[0032] Furthermore, a plurality of general winning holes 31 are provided on the left and right lower sides of the game area 19, and a general winning hole detection sensor 31a (see FIG. 4) is provided inside each of them to detect the passage of game balls. Additionally, within the area of ​​the game board, movable devices (not shown) that create visual effects are arranged in positions that do not interfere with the rolling of the game ball.

[0033] In the gaming machine 1 of this embodiment, when a gaming ball enters one of the various winning holes provided in the gaming area 19, the number of prize balls set for the winning hole into which the gaming ball entered (for example, three for the first starting hole 23, one for the second starting hole 24, fifteen for the first large winning hole 27 and the second large winning hole 28, and five for the general winning hole 31) is paid out from the gaming ball payout device 46 (see FIG. 4). Gaming balls that do not enter any of the above winning holes are discharged from the gaming area 19 through the outlet 32.

[0034] <2. Control configuration of gaming machine> Fig. 4 is a block diagram showing the control configuration of the gaming machine 1. The configuration (control configuration) for realizing the gaming operation control of the gaming machine 1 will be described with reference to the block diagram of Fig. 4. The gaming machine 1 of this embodiment is composed of a main control board 40 that is responsible for overall control of all gaming operations (gaming operation control), a presentation control board 41 that receives presentation control commands from the main control board 40 and is responsible for overall control of the execution of presentations by the presentation means, a payout control board 42 that controls the payout of prize balls, and a power supply board (not shown) that generates and supplies the power supply voltage required for the gaming machine 1 from an external power source.

[0035] [2.1 Main control board] The main control board 40 is equipped with a microprocessor that incorporates a CPU (Central Processing Unit) 40a (main control CPU), as well as a ROM (Read Only Memory) 40b (main control ROM) that stores a control program that describes the game operation control procedures, as well as 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 as a whole constitutes a microcomputer.

[0036] Although not shown, the main control board 40 also includes a CTC (Counter Timer Circuit) for implementing periodic interrupts, a function for generating pulse outputs at fixed intervals (bit rate generator), and a time measurement function, an interrupt controller circuit that performs interrupt enable / disable functions such as timer interrupts that provide interrupt signals to the CPU 40a, a reset circuit that can detect power-on / power-off and power supply abnormalities and output a system reset signal to reset the CPU 40a, a watchdog timer (WDT) circuit that monitors for abnormal operation of the control program, an IAT (Inhibit Outside Designated Area) circuit that monitors whether the program is being executed correctly within a preset address range, and a counter circuit for generating random numbers within a certain range using hardware.

[0037] The counter circuit includes a random number generation circuit that generates random numbers and a sampling circuit that samples random numbers from the random number generation circuit at predetermined timing, and functions as a 16-bit counter as a whole. The CPU 40a sends instructions to the sampling circuit depending on the processing status, thereby obtaining the value indicated by the random number generation circuit as a random number (0 to 65535) for determining whether or not a jackpot has been reached, and using this random number for determining whether or not a jackpot has been reached. Note that the random number for determining whether or not a jackpot has been reached is obtained by adding a software random number generated by appropriate software processing to a hard random number in order to prevent cheating, such as aiming for a win.

[0038] The main control board 40 is connected to a first start gate detection sensor 23a that detects entry of a gaming ball into the first start gate 23, a second start gate detection sensor 24a that detects entry of a gaming ball into the second start gate 24, a normal symbol gate detection sensor 26a that detects passage of a gaming ball through the normal symbol gate 26, a first large prize gate detection sensor 27a that detects entry of a gaming ball into the first large prize gate 27, a second large prize gate detection sensor 28a that detects entry of a gaming ball into the second large prize gate 28, a normal prize gate detection sensor 31a that detects entry of a gaming ball into the normal prize gate 31, and an OUT monitoring sensor 32a that detects gaming balls (out balls) discharged from the game area 19. The main control board 40 is capable of receiving detection signals output from these sensors. Therefore, the main control board 40 can determine which prize gate the gaming ball has entered based on the detection signals from each sensor.

[0039] Also connected to the main control board 40 are a normal electric role solenoid 25a that operates the normal electric role 25 that opens and closes the second starting opening 24, a first special electric role solenoid 29a that operates the first special electric role 29 that opens and closes the first large winning opening 27, and a second special electric role solenoid 30a that operates the second special electric role 30 that opens and closes the second large winning opening 28. The main control board 40 is capable of transmitting control signals for controlling these.

[0040] In addition, the special symbol display device 22a and the special symbol display device 22b are connected to the main control board 40. The main control board 40 is capable of transmitting control signals for controlling the display of the special symbols 1 and 2. Additionally, the composite display device 22c and the composite display device 22d are connected to the main control board 40. The main control board 40 is capable of transmitting control signals for controlling the display of various information displayed on the composite display device 22c and the composite display device 22d.

[0041] The main control board 40 is connected to the RAM clear switch 33 and is capable of receiving a detection signal from the RAM clear switch 33. The RAM clear switch 33 is operable when the front frame 4 is open, and is disposed, for example, on the main control board 40. The RAM clear switch 33 is, for example, a push button switch for inputting an instruction to initialize a predetermined area of ​​the RAM 40c.

[0042] Furthermore, the main control board 40 is connected to a performance indicator 34 . The performance indicator 34 is configured with, for example, a 7-segment display and functions as a display means capable of displaying performance information, which will be described later. The performance indicator 34 is mounted, for example, on the main control board 40 or the dispensing control board 42 in an easily visible position. The main control board 40 is capable of transmitting a control signal to the performance display 34 to cause the performance information to be displayed.

[0043] A payout control board 42 is connected to the main control board 40, and when it is necessary to pay out prize balls, a control command regarding the payout (a payout control command specifying the number of prize balls) can be sent to the payout control board 42.

[0044] In addition, an external centralized terminal board 43 for the frame is connected to the main control board 40 via a payout control board 42, making it possible to transmit specified game information (e.g., jackpot information, number of winning balls information, pattern change execution information, etc.) to an externally installed hall computer HC. 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.

[0045] The payout control board 42 is connected to a launch control board 45 that controls the launch device 44 and a game ball payout device 46 that pays out game balls. The main role of this payout control board 42 is to receive payout control commands from the main control board 40, control the payout of prize balls by the game ball payout device 46 based on the payout control commands, and send status signals to the main control board 40.

[0046] The game ball payout device 46 is provided with a supply shortage detection sensor 46a that detects a shortage of game balls and a ball counting sensor 46b that detects the game balls (prize balls) to be paid out, and the payout control board 42 is capable of receiving these detection signals. The game ball payout device 46 is also provided with a payout motor 46c that drives a ball payout mechanism (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.

[0047] The payout control board 42 is connected to a fullness detection sensor 47 that detects whether the upper tray 10 is full of game balls, and a front door open sensor 48 that detects whether the front frame 2 is open.

[0048] 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, front door open sensor 48, out-of-supply detection sensor 46a, and ball count 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, an out-of-supply signal indicating a shortage of game balls from the game ball payout device 46, a count error signal indicating a shortage of prize balls or an abnormality in the ball count sensor 46b, and a payout completion signal indicating the completion of the payout operation. 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 (out-of-supply error), and the full state of the upper tray 10 (ball jam error).

[0049] The payout control board 42 is also capable of transmitting an authorization signal to the launch control board 45 to authorize launch. Based on the authorization signal output from the payout control board 42, the launch control board 45 controls the energization of a launch solenoid (not shown) provided in the launch device 44, thereby realizing the launch of game balls by operating the launch operation handle 15. Specifically, the launch of game balls is permitted under the following conditions: a launch authorization signal is output from the payout control board 42 (launch authorization signal ON state), a touch sensor (not shown) provided on the launch operation handle 15 detects that the player is touching the handle, and a launch stop switch (not shown) provided on the launch operation handle 15 has not been operated. Therefore, when the launch authorization signal is not output (launch authorization signal OFF state), the launch operation is not executed even if the launch operation handle 15 is operated, and no game balls are launched. Furthermore, the launch strength of the game balls can be changed depending on the amount of operation of the launch operation handle 15. In addition, the payout control board 42 outputs a launch permission signal to the launch control board 45 on the condition that the main control board 40 has instructed the launch permission.

[0050] (Performance display) The main control board 40 is capable of transmitting a control signal to the performance display 34 to cause it to display predetermined performance information. Performance information is information that pachinko halls and relevant authorities want to confirm, and typical examples include information regarding the presence or absence of illegal prize ball cheating, such as excessive prize balls in the gaming machine 1, and the original ball output performance of the gaming machine 1. Therefore, unlike preview effects, the performance information itself is information that is not directly related to the progress of the game itself when a player is enjoying the game.

[0051] For this reason, the performance display 34 is provided inside the gaming machine 1, for example, on the main control board 40, payout control board 42, launch control board 45, relay board, presentation control board 41, or board case (protective cover that protects the board), in a position where the display information can be seen when the front frame 2 is in the open state.

[0052] Here, the performance information may specifically include the following information: (1) Information (specific ratio information) based on the value (α / β) obtained by dividing the total number of payout balls paid out as a result of winning during a specific state (total number of prize balls during a specific state: α) by the total number of balls discharged from the game area 19 during the specific state (number of balls discharged during a specific state: β) can be adopted as performance information. The above "total number of payouts" refers to the total number of game balls (prize balls) paid out when game balls enter (win) the winning slots (first start slot 23, second start slot 24, general winning slot 31, first large winning slot 27, second large winning slot 28). Furthermore, the state to be adopted as the specific state can be determined appropriately depending on the state under which performance information is desired to be grasped. In the case of this embodiment, any of a plurality of game states and a state during a jackpot game can be adopted. Furthermore, multiple types of states may be used as the measurement target. For example, all game states except for a jackpot game can be used, and the type to be measured can be determined appropriately. In addition, the total number of payouts may be calculated by excluding one or more specific winning ports from the measurement target (total number of payouts excluding specific winning ports). For example, the total number of payouts may be calculated by excluding the first large winning port 27 and the second large winning port 28 from the measurement target among the winning ports.

[0053] (2) Alternatively, the total number of payouts, the total number of payouts excluding specific winning slots, or the total number of balls that have been released may be measured, and the measurement results may be used as performance information.

[0054] In this embodiment, the total number of dispensed balls in the normal state (number of dispensed balls in normal state) and the total number of balls out in the normal state (number of balls out in normal state) are measured in real time, and the value obtained by dividing the number of dispensed balls in normal state by the number of balls out in normal state and multiplying this value by 100 (the value calculated by: number of dispensed balls in normal state ÷ number of balls out in normal state × 100) is displayed as performance information (hereinafter referred to as "normal state ratio information"). Note that the displayed value in this case is rounded to one decimal place. Therefore, the data on the number of payouts during normal play, the number of out balls during normal play, and the normal play ratio information are stored (memorized) in the corresponding areas of RAM 40c (the storage area for the total number of prize balls during specific play, the storage area for the number of out balls during specific play, and the specific ratio information storage area). However, rather than simply measuring continuously and displaying performance information, measurement is temporarily terminated when the total number of out balls reaches a predetermined number (e.g., 60,000). This specified number is not the total number of out balls during normal play, but the total number of out balls during all play states (including win play) (hereinafter referred to as the "number of out balls in all states"). This number of out balls in all states is also measured in real time and stored in the corresponding areas of RAM 40c (the storage area for the number of out balls in all states). For ease of explanation, the storage area for the total number of prize balls during specific play, the storage area for the number of out balls during specific play, the specific ratio information storage area, and the storage area for the number of out balls in all states will be abbreviated as the "measurement information storage area."

[0055] Then, the normal time ratio information at the end point is stored in a predetermined area (performance display storage area) of RAM 40c (the current normal time ratio information is stored), and then the measurement information storage area (the number of payouts in normal time, the number of balls out in normal time, and the number of balls out in all states) is cleared, and measurement begins again (measurement of the number of payouts in normal time, the number of balls out in normal time, the normal time ratio information, and the number of balls out in all states begins).The performance display 34 then displays the previous normal time ratio information (measurement history information) and the normal time ratio information currently being measured. Note that the configuration is not limited to the previous information, and history from the time before that or the time before that (three times before) may also be displayed, and the number of previous times of information to be displayed can be determined as appropriate.

[0056] (Performance control command) Depending on the processing status, the main control board 40 can transmit various presentation control commands, including information about the special symbol variation display game and information about errors, to the presentation control board 41. However, in order to prevent fraudulent activities such as cheating, the main control board 40 is configured for one-way communication, in which it only transmits signals to the presentation control board 41 and cannot receive signals from the presentation control board 41.

[0057] Here, the performance control command defines its function using a two-byte structure consisting of a one-byte mode (MODE) and a one-byte event (EVENT). To distinguish between MODE and EVENT, Bit 7 of MODE is ON and Bit 7 of EVENT is OFF. When this information is transmitted as valid, a strobe signal is output corresponding to each mode (MODE) and event (EVENT). That is, when there is a command to transmit, the CPU 40a (main control CPU) sets and outputs mode (MODE) information for transmitting the command to the performance control board 41, and transmits the first strobe signal a predetermined time after this setting. Furthermore, after a predetermined time has passed since transmitting this strobe signal, it sets and outputs event (EVENT) information, and transmits a second strobe signal a predetermined time after this setting. The strobe signal is controlled to an active state by the CPU 40a for a predetermined period of time to ensure that the CPU 41a (performance control CPU) can receive commands reliably.

[0058] [2.2 Performance control board] The performance control board 41 is equipped with a microprocessor with a built-in CPU 41a, and is composed mainly of a microcomputer equipped with a ROM 41b that stores the performance data required for performance control processing, and a RAM 41c that functions as a work area and buffer memory.In addition, it is equipped with an audio control unit (sound source IC), interface circuits with each unit, a random number generation circuit that generates random numbers for lotteries used in performances, a CTC for various time counts, a watchdog timer (WDT) circuit, an interrupt controller circuit that gives an interrupt signal to the CPU 41a, an RTC (Real Time Clock) function unit, a reset circuit, etc., which control the overall performance operation.

[0059] The CPU 41a performs calculations for various performance operations and controls each performance means based on the performance control program and performance control commands received from the main control board 40. In the case of the gaming machine 1 of this embodiment, the performance means are the liquid crystal display device 20 (main liquid crystal display device 20M, sub liquid crystal display device 20S), the light display device 16a, the sound generating device 17a, and movable role objects (not shown).

[0060] The ROM 41b stores a control program for the performance operation by the CPU 41a and various data required for performance operation control. The RAM 41c is used as a work area used by the CPU 41a for various arithmetic processing, a table data area, a buffer area for various input / output data and processing data, and the like.

[0061] The main roles of this performance control board 41 are to receive performance control commands from the main control board 40, select and decide on performances based on the performance control commands, control the display of the liquid crystal display device 20 (supply of display data), control the sound output of the sound generating device 17a, control the light emission of the light display device 16a, and control the operation of the movable body role device (drive control of the movable body role device motor 50).

[0062] This performance control board 41 also functions as a control device for the liquid crystal display device 20, so the performance control board 41 also has the functions of a so-called VDP (Video Display Processor), image ROM, and VRAM (Video RAM), and the CPU 41a also functions as a liquid crystal control unit. VDP refers to the function that controls all video output processes, such as image expansion and image drawing. Image ROM refers to memory that stores image data that the VDP uses for image development processing. VRAM is an image memory area that temporarily stores image data developed by the VDP.

[0063] With this configuration, the performance control board 41 generates various image data based on performance control commands from the main control board 40 and outputs it to the main liquid crystal display device 20M and the sub liquid crystal display device 20S. As a result, various performance images are displayed on the main liquid crystal display device 20M and the sub liquid crystal display device 20S. 3 is the "main liquid crystal display device 20M." The sub liquid crystal display device 20S is not shown in FIG.

[0064] The performance control board 41 also has an audio control section for an audio generating device 17 a including a plurality of speakers 17 , and the audio signals output by the audio control section are amplified by an amplifier section 17 b and supplied to the speakers 17 . Also connected to the performance control board 41 are a lamp driver section 16b that functions as a light display control section for the light display device 16a including the decorative lamp 16, and a motor driver section 50a (motor drive circuit) that functions as a drive control section for the movable body role motor 50 that operates the movable body (not shown). The performance control board 41 issues instructions to the lamp driver section 16b and the motor driver section 50a to control the light display operation by the light display device 16a and the operation of the movable body role motor 50.

[0065] In addition, an origin switch 51 and a position detection sensor 52 are connected to the performance control board 41 to monitor the operation of the movable props. The origin switch 51 is composed of, for example, a photointerrupter, and detects whether the movable body role motor 50 is at the origin position. The origin position is, for example, a position where the movable body is not normally exposed on the board surface of Figure 2. The performance control board 41 is capable of determining whether the movable body role motor 50 is at the origin position based on the detection information of this origin switch 51. In addition, the performance control board 41 controls the operation mode while monitoring the current operating position of the movable role object (for example, the amount of movement from the origin position) based on the detection information from the position detection sensor 52. Furthermore, the performance control board 41 monitors malfunctions in the operation of the movable role object based on the detection information from the position detection sensor 52, and if a malfunction occurs, detects it as an error.

[0066] In addition, operation detection switches for the performance button 14a, cross key 14b, and decision button 14c, which are shown as the operation unit 14, are connected to the performance control board 41, and the performance control board 41 is capable of receiving operation detection signals from the performance button 14a, cross key 14b, and decision button 14c, respectively.

[0067] Furthermore, the performance control board 41 is provided with a handle sensor 53 (touch sensor) for detecting whether or not the firing operation handle 15 shown in Fig. 1 is being touched by a player. The performance control board 41 is capable of determining whether or not the firing operation handle 15 is being touched by a user based on the detection information of the handle sensor 53.

[0068] Based on the performance control command sent from the main control board 40, the performance control board 41 selects (determines) a performance pattern by lottery or uniquely from multiple types of performance patterns prepared in advance, and controls various performance means at the required timing to produce the desired performance. This realizes the display of a performance image by the liquid crystal display device 20 corresponding to the performance pattern, the reproduction of sound from the speaker 17, and the lighting and flashing of the decorative lamps 16, and the chronological development of various performance patterns (such as decorative symbol variation display operations and preview performances), thereby realizing a "performance scenario" in the broad sense.

[0069] Here, for the performance control command, the performance control board 41 (CPU 41a) generates an interrupt process based on the input of the above-mentioned strobe signal transmitted by the main control board 40 (CPU 40a) and receives and analyzes the command. Specifically, the CPU 41a executes a control program for command reception interrupt processing based on the input of the above-mentioned strobe signal, and in the interrupt processing realized by this, obtains the performance control command and analyzes the command content. In this case, when an interrupt occurs based on the input of a strobe signal, the CPU 41a interrupts the interrupt processing based on another interrupt (a timer interrupt processing executed periodically) even if that processing is in progress, and performs the command reception interrupt processing, and even if another interrupt occurs at the same time, the command reception interrupt processing is performed with priority.

[0070] <3. Overview of operation> Next, an outline of the gaming operation of the gaming machine 1 realized by the above-described control configuration (FIG. 4) will be described.

[0071] [3.1 Game Status] The gaming machine 1 is configured to be able to set a plurality of types of gaming states in addition to a jackpot game, which is a special gaming state. To facilitate understanding of this embodiment, first, various gaming states will be described.

[0072] In the gaming machine 1, a game progresses in any one of the gaming states that combines either a low probability state or a high probability state with either a non-time-shortening state or a time-shortening state.

[0073] The low probability state is a state in which the probability of winning the jackpot lottery is relatively low, and the high probability state is a state in which the probability of winning the jackpot lottery is relatively high. The non-time-shortening state is a state in which it is relatively difficult for a gaming ball to enter the second starting hole 24, and the time-shortening state is a state in which it is relatively easy for a gaming ball to enter the second starting hole 24. For example, the opening time of the second starting hole 24 when the regular winning lottery is won is set longer in the time-shortening state than in the non-time-shortening state. However, if it is easier for a gaming ball to enter the second starting hole 24 in the time-shortening state than in the non-time-shortening state, the time-shortening state may, for example, have a higher probability of winning the regular winning lottery or a shorter fluctuation time of the regular symbol than in the non-time-shortening state.

[0074] In this embodiment, the "normal state" refers to a low probability state and a non-time-saving state, and corresponds to the initial state.

[0075] [3.2 Game with changing symbols] (Regarding special drawings) In the gaming machine 1, when a gaming ball enters the first starting hole 23 or the second starting hole 24, that is, when a detection signal is input from the first starting hole detection sensor 23a or the second starting hole detection sensor 24a, random numbers related to the special pattern change display game described below (random numbers for determining a jackpot, random numbers for determining special patterns, random numbers for change patterns) are obtained, and these random numbers are stored as reserved data in the special pattern reserved memory area of ​​RAM 40c up to a predetermined upper limit value, which is the maximum reserved memory number (for example, a maximum of 4). This special symbol reservation memory area is provided with special symbol reservation memory areas corresponding to the special symbol 1 side and the special symbol 2 side, that is, a special symbol 1 reservation memory area and a special symbol 2 reservation memory area.

[0076] These special symbol reserved memory areas are provided with reserved 1 memory area to reserved n memory area (n is the maximum reserved memory number: in this embodiment, n=4), and each is capable of storing reserved data up to the maximum reserved memory number. Note that the maximum reserved memory numbers of the special symbol 1 reserved memory area and the special symbol 2 reserved memory area are not particularly limited. In addition, all or part of the maximum reserved memory numbers of each symbol may be different, and the number can be determined appropriately depending on the gameplay. The game balls related to the reserved data stored in this special symbol reserved memory area are also called “reserved balls.” To make the number of reserved balls clear to the player, dot displays corresponding to the number of reserved balls of special symbol 1 and special symbol 2 on the composite display device 22c are lit, or a reserved indicator provided as an icon image on the screen of the liquid crystal display device 20 (main liquid crystal display device 20M or sub liquid crystal display device 20S) is lit.

[0077] (Special pattern change display game) In the gaming machine 1, a "jackpot lottery" is conducted by random number lottery on the main control board 40 based on a predetermined start condition, specifically, based on the entry (winning) of a gaming ball into the first start hole 23 or the second start hole 24. Based on the result of the jackpot lottery, the main control board 40 variably displays special symbols 1 and 2 on the special symbol display devices 22a and 22b to start the special symbol variable display game, and after a predetermined variation time has elapsed, displays the result on the special symbol display devices 22a and 22b, thereby ending the special symbol variable display game. Unless otherwise necessary, "special symbol 1" and "special symbol 2" will be simply referred to as "special symbols" (sometimes abbreviated as "special symbols").

[0078] In this embodiment, the lottery for a jackpot for special symbol 1 based on winning through the first starting hole 23 and the lottery for a jackpot for special symbol 2 based on winning through the second starting hole 24 are conducted separately and independently. For this reason, the result of the lottery for a jackpot for special symbol 1 is displayed on the special symbol display device 22a, and the result of the lottery for a jackpot for special symbol 2 is displayed on the special symbol display device 22b. Specifically, on the condition that a gaming ball has entered the first starting hole 23, the special symbol 1 is displayed in a variable manner to start a first special symbol variable display game, while on the other hand, on the condition that a gaming ball has entered the second starting hole 24, the special symbol 2 is displayed in a variable manner to start a second special symbol variable display game. Then, when the special pattern variable display game is started on the special pattern display device 22a or the special pattern display device 22b, after a predetermined variable time has elapsed, if the result of the jackpot lottery is a "jackpot", the special pattern being displayed in a static state will be displayed in a predetermined "jackpot" mode, or in a predetermined "miss" mode otherwise, thereby announcing the game result (jackpot lottery result).

[0079] For ease of explanation, the first special symbol variable display game on the special symbol display device 22a side will be 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 will be referred to as "special symbol variable display game 2." Furthermore, "special symbol variable display game 1" and "special symbol variable display game 2" will be simply referred to as "special symbol variable display games."

[0080] If the result of the jackpot lottery is a "jackpot," that is, if the special pattern change display game ends and as a result the special pattern is displayed stationary in a "jackpot" mode on the special pattern display device 22a or the special pattern display device 22b, a special game state (jackpot game) occurs that is more advantageous to the player than during the special pattern change display game.

[0081] (Decorative pattern changing game) Furthermore, when the special symbol variable display game is started, the decorative symbol variable display game is started by variably displaying decorative symbols (game symbols for dramatic effects) on the main liquid crystal display device 20M, and various effects are developed in association with this. When the special symbol variable display game ends, the decorative symbol variable display game also ends, and predetermined special symbols indicating the results of the jackpot lottery are displayed on the special symbol display devices 22a and 22b, and decorative symbols reflecting the results of the jackpot lottery are derived and displayed on the main liquid crystal display device 20M. In other words, the results of the special symbol variable display game are reflected and displayed by the decorative symbol variable display game for dramatic effects, including the variably displaying operation of the decorative symbols.

[0082] Therefore, for example, if the result of the special symbol variation display game is a "jackpot" (if the result of the jackpot lottery is a "jackpot"), an effect that reflects that result will be developed in the decorative symbol variation display game. Then, when the special symbol is stopped and displayed in a display mode that indicates a jackpot (for example, the 7-segment display shows "7") on the special symbol display devices 22a and 22b, the decorative symbols are stopped and displayed in a display mode that reflects the "jackpot" in each of the "left," "center," and "right" display areas on the main liquid crystal display device 20M (in each of the "left," "center," and "right" display areas, the three decorative symbols are stopped and displayed in the same display mode (for example, "7," "7," "7")).

[0083] Regarding the information necessary to execute the decorative pattern change display game, first, the main control board 40, based on the game ball entering the first start hole 23 or the second start hole 24, specifically, on the condition that the game ball is detected by the first start hole detection sensor 23a or the second start hole detection sensor 24a and the start condition (start condition related to the special pattern) is met, conducts a jackpot lottery to determine whether it will be a "jackpot" or a "miss", and a pattern lottery to determine the type of special pattern (jackpot type, miss type) that will finally be stopped and displayed, and determines the change pattern of the special pattern based on the results of the lottery. In the symbol lottery, if the result of the jackpot lottery is a "jackpot," one of multiple jackpot types will be selected by lottery, and if it is a "miss," one of multiple miss types will be selected by lottery. However, there may be only one jackpot type and one miss type, and in that case, the selection may be made without a lottery. Then, the main control board 40 transmits a "variation pattern designation command" including at least information on the variation pattern of the special symbols (variation pattern information (e.g., information on the result of the jackpot lottery and the variation time of the special symbols)) to the performance control board 41 as a performance control command that specifies the processing state. As a result, basic information required for the decorative symbol variation display game is sent to the performance control board 41.

[0084] The special symbol variation pattern information can include information specifying whether or not a specific preview effect (such as a "reach effect" or "pseudo consecutive effects" described below) will occur. Specifically, the variation patterns of the special symbols are broadly divided into a "jackpot variation pattern" for a jackpot and a "miss variation pattern" for a miss, depending on the result of the jackpot lottery. These variation patterns include, for example, a "reach variation pattern" that specifies the occurrence of a reach effect, a "normal variation pattern" that does not specify the occurrence of a reach effect, a "reach variation pattern with pseudo consecutive effects" that specifies the occurrence (overlapping occurrence) of a pseudo consecutive effect and a reach effect, and a "normal variation pattern without pseudo consecutive effects" that specifies the occurrence of a pseudo consecutive effect but does not specify the occurrence of a reach effect. Note that, in order to ensure the duration of the reach effect and pseudo consecutive effects, the variation time of a variation pattern that specifies a reach effect or pseudo consecutive effects is usually set to be longer than that of a normal variation pattern.

[0085] Based on information contained in the effect control commands (here, the variation pattern designation command and the decorative symbol designation command) sent from the main control board 40, the effect control board 41 determines the effect content (effect scenario, such as preview effects) to be developed in chronological order during the decorative symbol variation display game and the decorative symbols (decorative stop symbols) to be ultimately displayed. The effect control board 41 then executes the decorative symbol variation display game by displaying the decorative symbols in a variable manner according to a time schedule based on the variation pattern of the special symbols. As a result, the decorative symbols displayed by the main LCD display device 20M are displayed in a variable manner in time with the variable display of the special symbols by the special symbol display devices 22a and 22b, so that the duration of the special symbol variation display game and the duration of the decorative symbol variation display game are substantially the same. The effect control board 41 also controls the main LCD display device 20M, the light display device 16a, or the sound generating device 17a in accordance with the effect scenario to develop various effects in the decorative symbol variation display game. This allows the main liquid crystal display device 20M to reproduce images (image effects), reproduce sound effects (sound effects), and light and flash the decorative lamps 16, LEDs, etc. (light effects).

[0086] In this way, the special symbol variation display game and the decorative symbol variation display game have an inseparable relationship, and the display results of the special symbol variation display game are reflected in the decorative symbol variation display game, so these two symbol variation display games can be considered as equivalent symbol games. In this specification, unless otherwise necessary, the above two symbol variation display games may be simply referred to as "pattern variation display games."

[0087] (Regarding the reservation of general maps) In the gaming machine 1, when a game ball passes through the normal pattern gate 26, that is, when a detection signal is input from the normal pattern gate detection sensor 26a, a random number related to the normal pattern variable display game (random number for determining whether a normal pattern is a hit) is acquired, and this random number is held as reserved data in the normal pattern reserved memory area of ​​RAM 40c up to a predetermined upper limit value, which is the maximum number of reserved memories (for example, a maximum of 4). The general map reservation memory area has reservation 1 memory area to reservation n memory area (n is the maximum reservation memory number: in this embodiment, n = 4), each of which can store the maximum number of reserved data. There is no particular limit to the maximum number of reserved data in the general map reservation memory area. The game balls related to the reserved data stored in this normal reserved memory area are also called "normal reserved balls." To make the number of these normal reserved balls clear to the player, a dot indicator corresponding to the number of normal reserved balls on the composite display device 22c is lit, or a reserved indicator provided as an icon image on the screen of the liquid crystal display device 20 (main liquid crystal display device 20M or sub liquid crystal display device 20S) is lit.

[0088] (Normal pattern change display game) In the gaming machine 1, a "regular symbol winning lottery" is performed by random number lottery on the main control board 40 based on the passing of a gaming ball through the regular symbol gate 26. Based on the result of this lottery, the regular symbol represented by the LED is displayed variably on the composite display device 22d to start the regular symbol variable display game, and after a predetermined variable time has elapsed, the result is displayed as a static combination of lit and unlit LEDs. For example, if the result of the regular symbol winning lottery is a "regular symbol winning," specific LEDs on the composite display device 22d are displayed in a specific lighting state (for example, both LEDs are lit, or the LED representing a "circle" and an "x" is lit) depending on the type of regular symbol winning. Note that in this embodiment, only one type of regular symbol winning is provided.

[0089] When this "normal win" occurs, the normal electric accessory solenoid 25a (see FIG. 4) is activated, the second start hole 24 is opened or enlarged, and a state (start hole open state) is created in which game balls can easily flow in, creating a game state (hereinafter referred to as "normal electric open game") that is more advantageous to the player than when the second start hole 24 is closed. In this normal electric open game, the winning area is opened or enlarged by the normal electric accessory 25 until the opening time of the second start hole 24 has elapsed for a predetermined time (e.g., 5.7 seconds) or until the number of game balls that have entered the second start hole 24 reaches a predetermined number (e.g., 10), and when either of these conditions is met, the second start hole 24 is closed, and this operation is repeated a predetermined number of times (e.g., up to once).

[0090] [3.3 About the jackpot] Next, the "jackpot" in the gaming machine 1 will be explained. In the gaming machine 1, for example, "4R1", "10R", and "4R2" are set as the jackpot types, and if the result of the jackpot lottery is "jackpot", a lottery for the jackpot type is held in the pattern lottery. The above notation "R" means the specified number of rounds (maximum number of rounds).

[0091] The type of jackpot is the hit that triggers the activation of the conditional device. Here, the "conditional device" refers to a device whose operation is a necessary condition for the activation of the consecutive device for playing rounds, and which is activated when a specific combination of special symbols is displayed or when the game ball passes through a specific area inside the jackpot opening.

[0092] The jackpot game begins after a pre-opening interval (opening time) has elapsed, and then the first or second major prize opening 27, 28 is opened. A predetermined time (maximum opening time, e.g., 29.8) has elapsed since the opening, or the number of game balls entering the first or second major prize opening 27, 28 reaches a predetermined number (maximum number of wins). This "round game" is repeated for a predetermined number of rounds (the number of rounds depends on the type of jackpot). After the predetermined number of rounds, a post-opening interval (ending time) has elapsed, which notifies the player that the jackpot game is about to end. The "s" after the number stands for "seconds."

[0093] When a jackpot game is executed, the game state after the jackpot game ends, the number of chance variations, and the number of time reduction variations are determined according to the game state at the time of winning the jackpot and the determined type of jackpot. The number of chance variations is set when the game state after a jackpot game is a high probability state. In the gaming machine 1, the high probability state after a jackpot game continues until the number of times the special symbol variation display game is executed reaches the chance variation number (for example, 154 times), and when the special symbol variation display game reaches the chance variation number without winning a jackpot in the jackpot lottery, the game state is set (transitioned) to a low probability state. The number of time-saving times is set when the game state after a jackpot game is in the time-saving state. In the gaming machine 1, the time-saving state after a jackpot game continues until the number of times the special symbol variable display game is executed reaches the time-saving number (for example, 150 times), and when the special symbol variable display game reaches the time-saving number without winning a jackpot in the jackpot lottery, the game state is set (transitioned) to the non-time-saving state. However, the gaming machine 1 may be a "general probability variable machine" of the type in which the number of probability variable times and the number of time-saving times continue until a jackpot is won in the jackpot lottery (until the next time). The number of times the time is reduced may be the total number of times that the special pattern change display game 1 and the special pattern change display game 2 are executed (the total number of changes in special pattern 1 and special pattern 2), or it may be the number of times that either one of them is executed (for example, the number of times that the special pattern change display game 2 is executed).

[0094] In this embodiment, similar to the jackpot types, there are multiple loss types for "loss." Specifically, there are three loss types: "loss 1," "loss 2," and "loss 3." As described above, if the result of the jackpot lottery is a "miss," a lottery for the type of miss is held in the pattern lottery.

[0095] [3.4 Production] (Performance mode) Next, the presentation modes (presentation states) will be explained. The gaming machine 1 of this embodiment is provided with a plurality of presentation modes for producing presentations related to the game state, and is configured to be able to switch between these presentation modes. Specifically, a presentation mode corresponding to the set game state is provided. In each presentation mode, the background display as the background of the decorative pattern variable display screen is displayed with a different background presentation, so that the player can understand what game state he or she is currently in.

[0096] The presentation control board 41 (CPU 41a) has a functional unit (presentation state transition control means) that controls transitions between multiple presentation modes. The presentation control board 41 (CPU 41a) is configured to grasp the current game state and control transitions between multiple presentation modes in a manner that maintains consistency with the game state managed by the main control board 40 based on specific presentation control commands sent from the main control board 40 (CPU 40a), specifically, presentation control commands including game state information managed by the main control board 40. Examples of such specific presentation control commands include a variation pattern designation command, a decorative symbol designation command, and a game state designation command sent when a change occurs in the game state.

[0097] (Preview performance) Next, the preview effects will be explained. The effect control board 41 is configured to be able to control the appearance of various "preview effects" related to the current presentation mode and the jackpot lottery results based on the contents of the presentation control command from the main control board 40, specifically, based on at least the variation pattern information included in the variation pattern designation command. Such preview effects suggest (predict) the expected probability of winning a particular jackpot type (hereinafter referred to as "expected probability of winning") and act as "hype effects" to heighten the player's anticipation of winning. Typical preview effects include "reach effects," "pseudo consecutive effects," and even "predictive preview effects." The effect control board 41 functions as preview effect control means capable of controlling the execution (appearance) of these effects.

[0098] "Reach effect" refers to an effect mode accompanying a reach state (variable display mode accompanying a reach state: reach variation pattern), and more specifically, an effect mode in which the final game result is derived and displayed via a reach state. Reach effects include multiple types of reach effects associated with the probability of winning. For example, there are some in which the probability of winning is relatively higher than when a normal reach effect appears. Such reach effects are called 'super reach effects'. Many of these "super reaches" have a relatively longer presentation time (variation time) than normal reaches to increase the expectation of winning. Furthermore, normal reaches and super reaches include multiple types of reach effects. Super reaches include multiple types of reach effects, namely Super Reach 1, 2, 3, and 4, and the probability of winning of these Super Reaches 1 to 4 has the following relationship: "Super Reach 1 < Super Reach 2 < Super Reach 3 < Super Reach 4."

[0099] "Pseudo consecutive effects" refers to an effect mode accompanied by a pseudo continuous change display state (pseudo consecutive changes) of decorative symbols, and "pseudo consecutive changes" refers to a change display mode in which, during a decorative symbol change display game, some or all of the decorative symbols are temporarily put into a temporary stop state, and then a re-changing display operation of the decorative symbols is executed from that temporary stop state, and this display operation is repeated once or multiple times. In this respect, it differs from the "prediction notice effect (continuous notice effect)" described below, which is developed across multiple symbol change display games. The occurrence rate (appearance rate) of such "pseudo consecutive effects" is basically set so that the more pseudo changes there are, the higher the probability of winning. For example, depending on the number of pseudo changes, effects that stimulate expectations such as a super reach are more likely to be selected.

[0100] "Prediction prediction effect" (hereinafter sometimes abbreviated as "prediction prediction" or "prediction effect") refers to an effect that notifies the player of the possibility of being controlled to an advantageous state before the variable display of the symbol to be judged is carried out based on the results of the prediction judgment. "Advantageous state" means a state that is advantageous to the player. Specifically, the pre-reading effect is performed in a presentation mode that can notify the winning expectation in advance of reserved balls (unconsumed reserved balls) that have not yet been used in the execution of the pattern change display game (the operation of displaying the variation of special symbols), mainly by utilizing the reserved display mode and the background presentation of the pattern change display game that is executed first. In the pattern change display game, in addition to the above-mentioned "reach presentation," various presentations such as so-called "SU (step-up) notice presentation," "timer notice presentation," "revival presentation," and "premium notice presentation" are generated to liven up the game content.

[0101] Here, with reference to FIG. 5, a "hold change notice effect" will be described as an example of the above-mentioned look-ahead notice effect. In the gaming machine 1 of this embodiment, the upper display area of ​​the screen of the main liquid crystal display device 20M is provided with a display area for displaying the decorative symbol variation display game (a display area for displaying decorative symbol variation display effects and preview effects), and the lower display area of ​​the screen is provided with a reserved display area 60 (reserved display sections a1 to d1) that displays the number of reserved balls on the special symbol 1 side, and a reserved display area 61 (reserved display sections a2 to d2) that displays the number of reserved balls on the special symbol 2 side. The presence or absence of reserved balls is notified by a predetermined reserved display mode. Figure 5 shows an example in which the presence or absence of reserved balls is indicated by a lit state (reserved balls: "○ (white circle)" shown in the figure) or an unlit state (no reserved balls: dashed circle shown in the figure), and information regarding the current number of reserved balls is notified.

[0102] The display of reserved balls (reserved display) is displayed in order of occurrence (winning order), and in each reserved display area 60, 61, the leftmost reserved ball is displayed as the reserved ball that occurred first on the time axis (i.e., the oldest) among all reserved balls in that reserved display. Also, to the left of the reserved display areas 60, 61, a changing display area 62 is provided to show the reserved balls currently being used in the special symbol variable display game. In this embodiment, the changing display area 62 is configured so that an image of the game-playing reserved ball K icon currently being used in the game is displayed on top of the seat J icon. That is, when the variable display of special symbol 1 or special symbol 2 begins, the icon (icon image) of the oldest reserved display section a1 or a2 displayed in the reserved display area 60, 61 moves to the icon of seat J in the changing display area 62 as the game-playing reserved ball K icon, and this state is maintained for a predetermined display time.

[0103] When a reserved ball occurs, the main control board 40 sends to the performance control board 41 a "reserved addition command" that specifies the advance reading judgment information related to the jackpot lottery result and the number of reserved balls at the time of advance reading judgment (the number of reserved balls currently existing, including the reserved ball that has occurred this time). In this embodiment, the above-mentioned reserve addition command is composed of two bytes, and the reserve addition command is composed of data on the upper byte side that enables the number of reserved balls to be identified at the time of the pre-reading judgment, and data on the lower byte side that enables the pre-reading judgment information to be identified.

[0104] As can be understood from the above explanation, in this embodiment, when a game ball enters the first start hole 23 or the second start hole 24 and a new reserved ball is generated, a jackpot lottery for the symbol variation display game related to the reserved ball is performed as a pre-reading judgment. The main control board 40 reserves and stores the pre-reading judgment information obtained by such pre-reading judgment in the corresponding storage area of ​​the RAM 40c.

[0105] Here, the pre-reading judgment information is specifically game information obtained by the main control board 40 by pre-reading and judging the jackpot lottery result (jackpot lottery result at the start of the variation) executed when the reserved ball is provided to the symbol variation display game and the variation pattern at the start of the variation. That is, this information includes at least information obtained by pre-reading and judging the jackpot lottery result at the start of the variation (pre-reading success / failure information), and can also include information obtained by pre-reading and judging the symbol lottery result (pre-reading symbol information) and information obtained by pre-reading and judging the variation pattern at the start of the variation (pre-reading variation pattern information). The information included in the reserved addition command to be sent to the performance control board 41 can be determined appropriately depending on the content to be notified in the pre-reading notice. It should be noted that the pending addition command includes predictive win / loss information, predictive pattern information, and predictive variation pattern information.

[0106] When the performance control board 41 receives the above-mentioned hold addition command sent by the main control board 40, it performs performance control processing for the "pre-reading notice performance" as part of the display control processing related to the above-mentioned hold display based on the pre-reading judgment information contained therein. Specifically, it performs a "pre-reading notice lottery" to draw whether or not the pre-reading notice performance can be executed, and if it is won, it makes the pre-reading notice performance appear.

[0107] It should be noted that the "pre-read fluctuation pattern" obtained by the pre-read judgment when the reserved ball occurs does not necessarily have to be the "fluctuation pattern at the start of fluctuation" itself obtained when the reserved ball is actually used for the fluctuation display operation. For example, to explain a representative case where the fluctuation pattern at the start of fluctuation is a fluctuation pattern that specifies "Super Reach 1", in this case, it is possible to specify that the content specified by the pre-read fluctuation pattern is not the type of reach performance itself called "Super Reach 1", but rather the "Super Reach type" which is its essential element.

[0108] In this embodiment, if the advance notice lottery is won, a "hold display change" advance notice performance (also referred to as a "hold change notice") is performed in which the hold icon that is the subject of the advance notice among the hold icons in the hold display sections a1 to d1, a2 to d2 is changed from the white of the normal hold display (normal hold display mode) to a hold display (special hold display mode) with a notice display of blue, green, red, or a danger pattern (or special colors or patterns such as rainbow colors). In Figure 5, the reserved ball in the hatched reserved display section b1 is shown as a special reserved display. Here, the reserved icon blue, green, red, and danger pattern display indicate a higher probability of winning in this order, and the danger pattern reserved icon display is a premium reserved icon that indicates an extremely high probability of winning a jackpot.

[0109] (Direction means) Various effects in the gaming machine 1 are produced by the effect means provided in the gaming machine 1. These effect means may be any stimulus transmission means capable of producing effect effects by appealing to human senses, such as sight, hearing, or touch. Representative examples include light-generating means (light display device 16a: light effect means) such as decorative lamps 16 and LED devices, sound-generating devices (sound generating device 17a: sound effect means) such as speakers 17, effect display devices (display means) such as the main LCD display device 20M and the sub-LCD display device 20S, pressure devices that transmit contact pressure to the operator's body, wind pressure devices that apply wind pressure to the player's body, and movable gadgets that produce visual effects through their movement. Here, effect display devices, like image display devices, are visually appealing displays, but differ from image display devices in that they also include devices that do not rely on images (e.g., 7-segment displays). The term "image display device" primarily refers to a type that produces effects by displaying images; devices that produce effects through means other than images, such as 7-segment displays, are included within the concept of effect display devices.

[0110] <4. Board connection configuration> The supply path of the power supply voltage to each board provided in the gaming machine 1 will be described.

[0111] Figure 6 is a power supply system diagram of the gaming machine 1. As shown in Figure 6, the gaming machine 1 is equipped with a power supply board 70, a gaming ball dispenser connection terminal board 71, a relay board 72, and a power supply relay board 73 in addition to the main control board 40, the performance control board 41, and the payout control board 42 described above. Note that each of these boards is a part of the boards mounted on the gaming machine 1, and various boards are provided in addition to those shown in the figure. Furthermore, the relay board 72 is a board that relays the payout control board 42 and other boards (for example, the frame external centralized terminal board 43, the launch control board 45), and one or more relay boards are provided, but for convenience of explanation, only one is shown.

[0112] The power supply board 70 receives AC input power (24V AC) from the outside and generates DC voltages that serve as operating power sources for various components based on the input AC input power (24V AC). The power supply board 70 generates 35V DC voltage (DC35VA), 12V DC voltages (DC12VA, DC12VB), and 5V DC voltages (DC5VA, DC5VB) from the AC input power.

[0113] The power supply board 70 is connected to the payout control board 42 and the game ball dispenser connection terminal board 71 via a transmission line H1. One end of the transmission line H1 is connected to the power supply board 70, and the other end branches off and is connected to the payout control board 42 and the game ball dispenser connection terminal board 71. The power supply board 70 supplies 35V DC voltage (DC35VA), 12V DC voltage (DC12VA), and 5V DC voltage (DC5VA) to the payout control board 42 via the transmission line H1. The power supply board 70 also supplies AC input power (AC24V) to the game ball dispenser connection terminal board 71 via the transmission line H1. The game ball dispenser connection terminal board 71 is connected to the game ball dispenser and transmits and receives various signals to and from the game ball dispenser.

[0114] The dispensing control board 42 is connected to the main control board 40 via a transmission line H2. The dispensing control board 42 generates a backup power supply (VBB) based on a 5V DC voltage (DC5VA) that is supplied to RAM 40c and the RAM of the integrated circuit IC7 (see FIG. 9) when the power is cut off. By supplying the backup power supply (VBB) to RAM 40c and the RAM of the integrated circuit IC7 when the power is cut off, it becomes possible to back up (retain) the data stored in RAM 40c and the RAM of the integrated circuit IC7 for a certain period of time (for example, one day or more). The dispensing control board 42 supplies 35V DC voltage (DC35VA), 12V DC voltage (DC12VA), 5V DC voltage (DC5VA) and backup power supply (VBB) to the main control board 40 via transmission line H2.

[0115] Dispensing control board 42 generates 5V DC voltage (DC5VH) based on 12V DC voltage (DC12VA). Dispensing control board 42 is also connected to relay board 72 via transmission line H3. Dispensing control board 42 supplies 35V DC voltage (DC35VA), 12V DC voltage (DC12VA), and 5V DC voltage (DC5VH) to relay board 72 via transmission line H3.

[0116] The power supply board 70 is also connected to the performance control board 41 via transmission line H4, power supply relay board 73, and transmission line H5. The power supply board 70 supplies 12V DC voltage (DC12VB) and 5V DC voltage (DC5VB) to the performance control board 41 via transmission line H4, power supply relay board 73, and transmission line H5.

[0117] <5. Configuration of the dispensing control board> [5.1 Structure of the dispensing control board] Fig. 7 is a diagram showing the wiring pattern on component side 42a of dispensing control board 42. Fig. 8 is a diagram showing the wiring pattern on solder side 42b of dispensing control board 42. Fig. 9 is a layout diagram of electronic components on dispensing control board 42. Note that Fig. 8 is a diagram that is flipped left to right to make it easier to understand the connection relationship with Figs. 7 and 9. Fig. 10 is a diagram showing the diameters of the through holes provided in the dispensing control board 42. Fig. 11 is a diagram explaining the legend of the diameters shown in Fig. 10. For the sake of convenience, only a portion of the electronic components and wiring patterns mounted on the dispensing control board 42 will be described below.

[0118] As shown in Figures 7 and 8, the dispensing control board 42 is a double-sided board with a ground pattern 42c as a solid ground formed on the component side 42a, which is the front surface, and a solder side 42b, which is the back surface, and with multiple conductive wiring patterns formed on them. As shown in Figures 10 and 11, the dispensing control board 42 has multiple through holes of different diameters formed therein, and the wiring patterns formed on the component side 42a and the solder side 42b are electrically connected via these through holes. Details of the wiring patterns and through holes will be described later.

[0119] In this embodiment, a "through hole" is a hole that penetrates the component surface 42a and the solder surface 42b and is plated with a conductive material, and includes a through hole into which a terminal of an electronic component is inserted, a through hole via that electrically connects the wiring patterns on the component surface 42a and the solder surface 42b, etc.

[0120] As shown in Fig. 9, multiple electronic components are mounted on the dispensing control board 42. All of the electronic devices are lead components, and the terminals (leads) of the electronic components arranged on the component surface 42a side are inserted into the through holes and then soldered from the solder surface 42b side to be fixed to the dispensing control board 42 and electrically connected to the wiring patterns formed on the component surface 42a and the solder surface 42b.

[0121] In this way, all electronic components of the payout control board 42 are arranged on one side, the component side 42a, and the component side 42a is attached to the back of the game board 5 so that it can be seen visually. Therefore, when the payout control board 42 is attached to the game board 5, it is possible to check (visually check) the electronic components mounted on the payout control board 42.

[0122] The electronic components include connectors CN (CN1 to CN7), integrated circuits IC (IC1 to IC22), resistors R (R1 to R97), capacitors C (C1 to C79), noise removal filters FLT (FLT1 to FLT10), switches SW (SW1 to SW4), and a 7-segment display FND (FND1). These electronic components are soldered and fixed to the dispensing control board 42 at the positions shown in FIG.

[0123] For example, the connector CN1 is connected to the transmission line end of the transmission line H1 (see FIG. 6) that connects to the power supply board 70. Therefore, various operating power sources (DC voltages) are supplied to the dispensing control board 42 via the connector CN1. The connectors CN2 and CN6 are connected to the relay board 72 via the transmission line H3 (see FIG. 6). The connector CN3 is connected to the transmission line end of the transmission line H2 (see FIG. 6) that connects to the main control board 40. Therefore, the dispensing control board 42 supplies (outputs) various operating power supplies (DC voltages), backup power supplies (VBB), and various signals to the main control board 40 via the connector CN3. Connector CN4 is connected to the transmission line end of the transmission line that connects the game ball lending device connection terminal board 71, and transmits various signals between the payout control board 42 and the game ball lending device connection terminal board 71.

[0124] [5.2 Input / output voltage of the dispensing control board] 12 is a diagram explaining the input / output voltages and supply destinations of the dispensing control board 42. As described above, the dispensing control board 42 is supplied with 35V DC voltage (DC35VA), 12V DC voltage (DC12VA), and 5V DC voltage (DC5VA) from the power supply board 70.

[0125] As shown in Figure 12, the 35V DC voltage (DC35VA) supplied from the power supply board 70 has a maximum current capacity set to 2.5A, and is supplied mainly to the main control board 40 (first special electric role solenoid 29a, second special electric role solenoid 30a), the launch solenoid provided in the launch device 44, and the ball feed solenoid (not shown) that sends game balls to the launch device 44.

[0126] The 12V DC voltage (DC12VA) supplied from the power supply board 70 has a maximum current capacity set to 5.0A, and is supplied mainly to the main control board 40 (normal electric role solenoid 25a, proximity switch, various function display units, magnetic sensor, vibration sensor, solenoid, etc.), payout motor 46c, and proximity switch. Note that the proximity switch is a sensor that detects the passage of a gaming ball, such as the first start hole detection sensor 23a or the supply shortage detection sensor 46a.

[0127] The 5V DC voltage (DC5VA) supplied from the power supply board 70 has a maximum current capacity set to 2.5A and is mainly supplied to the main control board 40 (CPU 40a) and the integrated circuit IC7 provided on the dispensing control board 42, and is also used to generate control signals on the dispensing control board 42.

[0128] Furthermore, the payout control board 42 generates (in-house) a 5V DC voltage (DC5VH) based on the 12V DC voltage (DC12VA) supplied from the power supply board 70. The 5V DC voltage (DC5VH) has a maximum current capacity set to 1.0A, and is supplied mainly to a handle volume (not shown) provided on the launching device 44 that detects the amount of operation of the launching operation handle 15, and a touch sensor (not shown) that detects whether the player is touching the handle.

[0129] Therefore, the 5V DC voltage (DC5VA) supplied from the power supply board 70 and the 5V DC voltage (DC5VH) generated by the payout control board 42 are the same voltage, but have different maximum current capacities and supply destinations. In particular, the 5V DC voltage (DC5VA) supplied from the power supply board 70, which is a stable operating power source, is supplied to supply destinations directly related to game control, such as the CPU 40a and integrated circuit IC7. On the other hand, the 5V DC voltage (DC5VH) generated by the payout control board 42 is supplied to supply destinations not directly related to game control, such as the handle volume and touch sensor (supply destinations related to the launch of game balls).

[0130] In addition, the dispensing control board 42 generates (in-house) a backup power supply (VBB) based on the 5V DC voltage (DC5VA) supplied from the power supply board 70. The backup power supply (VBB) is mainly supplied to the main control board 40 (RAM40c) and the RAM of the integrated circuit IC7.

[0131] In addition, the operating power supplies (output voltages) output from the dispensing control board 42 include 35V DC voltage (DC35VA), 12V DC voltage (DC12VA), 5V DC voltage (DC5VA), 5V DC voltage (DC5VH) and backup power supply (VBB).

[0132] The 35V DC voltage (DC35VA) output from the payout control board 42 has a maximum current capacity set to 1.3A, and is mainly supplied to the main control board 40 (first special electric device solenoid 29a, second special electric device solenoid 30a).

[0133] The 12V DC voltage (DC12VA) output from the dispensing control board 42 has a maximum current capacity set to 3.0A, and is mainly supplied to the main control board 40 (ordinary electric device solenoid 25a, proximity switch, various function display units, magnetic sensor, vibration sensor, solenoid, etc.), dispensing motor 46c, frame control switch, and proximity switch.

[0134] The 5V DC voltage (power supply voltage: DC5VA generated by the power supply board 70) output from the dispensing control board 42 has a maximum current capacity set to 1.0A and is mainly supplied to the main control board 40 (CPU 40a).

[0135] The 5V DC voltage output from the dispensing control board 42 (power supply voltage: DC5VH generated by the dispensing control board 42) has a maximum current capacity set to 1.0A and is mainly supplied to the handle volume and touch sensor.

[0136] The backup power supply (VBB) output from the dispensing control board 42 is mainly supplied to the main control board 40 (RAM40c).

[0137] [5.3 Circuit configuration of dispensing control board 42] Figure 13 is a diagram showing the circuit configuration to which connector CN1 is connected among the circuit configurations provided on dispensing control board 42.

[0138] 13, the connector CN1 for connecting to the power supply board 70 has 26 terminals numbered "1" to "26," from pin 1 to pin 26. For ease of explanation, the term "pin" of an electronic component does not refer only to male terminals in the shape of leads (terminals), but also includes both male and female terminals, and also includes so-called planar contact patterns and terminals corresponding thereto.

[0139] The first pin, second pin, seventh pin, eighth pin, thirteenth pin, fourteenth pin, and nineteenth to twenty-sixth pins are ground terminals. The third to sixth pins are terminals for a 35V DC voltage (DC35VA), and a 35V DC voltage (DC35VA) is input from the power supply board 70.

[0140] As shown in FIG. 14, the connector CN3 for connecting to the main control board 40 has 34 terminals, from the 1st pin to the 34th pin, as indicated by the numbers "1" to "34." Pins 1, 2, 7, 8, 13, 14, 18, 19, 22, 30, 33, and 34 are ground terminals.

The fourth and sixth pins are terminals for the backup power supply (VBB), and output the backup power supply (VBB) to the main control board 40. The ninth and eleventh pins are terminals for a 12V DC voltage (DC12VA), and output the 12V DC voltage (DC12VA) to the main control board 40. The 10th and 12th pins are terminals for a 5V DC voltage (DC5VA), and output the 5V DC voltage (DC5VA) to the main control board 40. The 15th and 17th pins are terminals for a 35V DC voltage (DC35VA), and output a 35V DC voltage (DC35VA) to the main control board 40. The 16th pin is assigned as a terminal for an asynchronous serial signal (CRX1) output from the dispensing control board 42. The 20th pin is assigned as a terminal for an asynchronous serial signal (CTX1) input from the main control board 40. Pins 21 and 23 are assigned as terminals for the open signal of the front frame 4 (open signal below the frame). The 24th pin, the 26th pin, the 28th pin, and the 32nd pin are assigned as terminals for various data signals (SS, DATA, RESET, CLK) input from the main control board 40. The 25th and 27th pins are assigned as terminals for the open signal of the front frame 4 (open signal on the frame). Pin 29 is assigned as the terminal for the launch control signal. The 31st pin is assigned as a terminal for an RWM clear signal for clearing the RAM 40c.

[0141] The power supply abnormality signal, asynchronous serial signal, frame bottom open signal, frame top open signal, and RWM clear signal are input via an integrated circuit IC2 that functions as a Schmitt trigger buffer.

[0142] As shown in Figure 15, the integrated circuit IC7 has a 71-terminal configuration from pin 1 to pin 71, numbered "1" to "71." The integrated circuit IC7 has a built-in CPU, RAM, and ROM, and the CPU operates using a 5V DC voltage (DC5VA) supplied via pins 8, 19, and 52, controlling each part of the payout control board 42, the launch device 44, and the game ball payout device 46.

[0143] The CPU of the integrated circuit IC7 controls the operation of each part of the payout control board 42, the launching device 44, and the game ball payout device 46, and the RAM stores data (information) necessary to control the operation of each part of the payout control board 42, the launching device 44, and the game ball payout device 46. In addition, the RAM is supplied with a backup power supply (VBB) via pin 20, and by supplying the backup power supply (VBB) when the power is cut off, the stored data can be backed up (retained).

[0144] [5.4 35V DC voltage supply wiring] Fig. 16 is a composite diagram of a wiring pattern for a 35V DC voltage (DC35VA). Fig. 16 is a composite diagram of the wiring pattern provided on component side 42a shown in Fig. 7, the wiring pattern provided on solder side 42b shown in Fig. 8, and the supply wiring for a 35V DC voltage (DC35VA) from the third to sixth pins (CN1_3 to CN1_6) of connector CN1 to the fifteenth and seventeenth pins (CN3_15, CN3_17) of connector CN3, extracted from the electronic components arranged on dispensing control board 42 shown in Fig. 9.

[0145] As shown in Figures 7 to 9, 13, 14, and 16, in the dispensing control board 42, a 35V DC voltage (DC35VA) is input from the power supply board 70 via the four third to sixth pins (CN1_3 to CN1_6) of the connector CN1.

[0146] The four third to sixth pins (CN1_3 to CN1_6) of the connector CN1 are connected to one end of a wiring pattern L35b_1 on the solder surface 42b. One end of a wiring pattern L35a_1 on the component surface 42a is connected to the middle of the wiring pattern L35b_1 via four through holes T35_1 to T35_4. One end of a wiring pattern L35b_2 on the solder surface 42b is connected to the other end of the wiring pattern L35a_1 via four through holes T35_5 to T35_8. The fifteenth and seventeenth pins (CN3_15, CN_17) of the connector CN3 are connected to the other end of the wiring pattern L35b_2.

[0147] Therefore, the 35V DC voltage (DC35VA) input to the four 3rd to 6th pins (CN1_3 to CN1_6) of connector CN1 is supplied to the 15th and 17th pins (CN3_15, CN_17) of connector CN3 through wiring pattern L35b_1, wiring pattern L35a_1, and wiring pattern L35b_2, and is output to the main control board 40 from the 15th and 17th pins (CN3_15, CN_17) of connector CN3.

[0148] The other end of the wiring pattern L35b_1 is connected to the integrated circuit IC22, and a 35V DC voltage (DC35VA) is supplied to the integrated circuit IC22 via the wiring pattern L35b_1. The 35V DC voltage (DC35VA) supplied to the integrated circuit IC22 is used as the operating power source for the launch solenoid and ball-feed solenoid, and is therefore output to the launch device 44 via the connector CN6.

[0149] Further, a part of the wiring pattern L35b_1 is supplied to a power supply abnormality signal generating circuit via a noise removal filter FLT1, etc. The power supply abnormality signal generating circuit is mainly composed of an integrated circuit IC5, resistors R16 to R21, capacitors C20 to C26, and a part of the integrated circuit IC3. The power supply abnormality signal generating circuit monitors voltage drops in the 35V DC voltage (DC35VA) and a 12V DC voltage (DC12VA) described below, and when the voltage drops below a predetermined threshold, it outputs a power supply abnormality signal (ABNORMAL) to the main control board 40 via pins 3 and 5 of the connector CN3 and inputs it to pin 70 of the integrated circuit IC7.

[0150] [5.5 12V DC voltage supply wiring] Fig. 17 is a composite diagram of the wiring pattern for 12V DC voltage (DC12VA). Fig. 17 is a composite diagram of the wiring pattern provided on component surface 42a shown in Fig. 7, the wiring pattern provided on solder surface 42b shown in Fig. 8, and the supply wiring for 12V DC voltage (DC12VA) from the 9th pin to the 12th pin (CN1_9 to CN1_12) of connector CN1 to the 9th pin and the 11th pin (CN3_9, CN3_11) of connector CN3, extracted from the electronic components arranged on dispensing control board 42 shown in Fig. 9.

[0151] As shown in Figures 7 to 9, 13, 14, and 17, in the dispensing control board 42, a 12V DC voltage (DC12VA) is input from the power supply board 70 via the four 9th to 12th pins (CN1_9 to CN1_12) of the connector CN1.

[0152] The four 9th to 12th pins (CN1_9 to CN1_12) of the connector CN1 are connected to one end of a wiring pattern L12b_1 on the solder surface 42b. The other end of the wiring pattern L12b_1 is connected to one end of a wiring pattern L12a_1 on the component surface 42a via nine through holes T12_1 to T12_9. The wiring pattern L12a_1 branches into wiring patterns L12a_2 and L12a_3, and an end of the wiring pattern L12a_2 is connected to one end of a wiring pattern L12b_2 on the solder surface 42b via six through holes T12_10 to T12_15. The 9th and 11th pins (CN3_9, CN3_11) of the connector CN3 are connected to the other end of the wiring pattern L12b_2.

[0153] Therefore, the 12V DC voltage (DC12VA) input to the four 9th to 12th pins (CN1_9 to CN1_12) of connector CN1 is supplied to the 9th and 11th pins (CN3_9, CN3_11) of connector CN3 through wiring patterns L12b_1, L12a_1, L12a_2, and L12b_2, and is output to the main control board 40 from the 9th and 11th pins (CN3_9, CN3_11) of connector CN3.

[0154] On the other hand, the end of the wiring pattern L12a_3 is connected to the noise reduction filter FLT2, and the 12V DC voltage (DC12VA) that passes through the noise reduction filter FLT2 is supplied to the power supply abnormality signal generating circuit, integrated circuits IC12 to IC15, IC18, the 24th pin of the connector CN2, the 4th pin, the 6th pin, the 18th pin of the connector CN6, etc.

[0155] The integrated circuits IC12 and IC13 are circuits for controlling the display of the 7-segment display FND1, and operate on the supplied 12V DC voltage (DC12VA) and a 5V DC voltage (DC5VA) described later to display information on the 7-segment display FND1. The 7-segment display FND1 can display performance information, similar to the performance indicator 34.

[0156] Furthermore, the 12V DC voltage (DC12VA) that has passed through the noise reduction filter FLT2 is supplied to the integrated circuit IC1. The integrated circuit IC1 is an LDO (Low Drop Out) regulator that generates a 5V DC voltage (DC5VH) from the supplied 12V DC voltage (DC12VA). The 5V DC voltage (DC5VH) generated by the integrated circuit IC1 is supplied to the first pin (CN4_1) of the connector CN4 via the noise reduction filter FLT9. As a result, the 5V DC voltage (DC5VH) is output to the game ball dispenser via the first pin (CN4_1) of the connector CN4 and the game ball dispenser connection terminal board 71.

[0157] In addition, the 5V DC voltage (DC5VH) generated by the integrated circuit IC1 also serves as the operating voltage for the volume sensor and touch sensor.

[0158] [5.6 5V DC voltage supply wiring] Fig. 18 is a composite diagram of the wiring pattern for a 5V DC voltage (DC5VA). Fig. 18 is a composite diagram of the wiring pattern provided on component side 42a shown in Fig. 7, the wiring pattern provided on solder side 42b shown in Fig. 8, and the wiring for supplying a 5V DC voltage (DC5VA) from the 15th to 18th pins (CN1_15 to CN1_18) of connector CN1 to the 10th and 12th pins (CN3_10, CN3_12) of connector CN3, extracted from the electronic components arranged on dispensing control board 42 shown in Fig. 9.

[0159] As shown in Figures 7 to 9, 13, 14, and 18, in the dispensing control board 42, a 5V DC voltage (DC5VA) is input from the power supply board 70 via the four 15th to 18th pins (CN1_15 to CN1_18) of the connector CN1.

[0160] The four 15th to 18th pins (CN1_15 to CN1_18) of the connector CN1 are connected to one end of a wiring pattern L5b_1 on the solder surface 42b. The other end of the wiring pattern L5b_1 is connected to one end of a wiring pattern L5a_1 on the component surface 42a via two through holes T5_1 to T5_2. The other end of the wiring pattern L5a_1 is connected to the middle of a wiring pattern L5b_2 on the solder surface 42b via two through holes T5_3 to T5_4. The 10th and 12th pins (CN3_10, CN3_12) of the connector CN3 are connected to one end of the wiring pattern L5b_2.

[0161] Therefore, the 5V DC voltage (DC5VA) input to the four 15th to 18th pins (CN1_15 to CN1_18) of connector CN1 is supplied to the 10th and 12th pins (CN3_10, CN3_12) of connector CN3 through wiring patterns L5b_1, L5a_1, and L5b_2, and is output to the main control board 40 from the 10th and 12th pins (CN3_10, CN3_12) of connector CN3.

[0162] The other end of the wiring pattern L5b_2 is connected to a noise elimination filter FLT3, and the 5V DC voltage (DC5VA) that passes through the noise elimination filter FLT3 is supplied to the DC5VA monitoring circuit, the backup power generation circuit 80, etc., and is also supplied as an operating power source to each part (for example, integrated circuits IC2, IC7 to IC11, IC17) of the dispensing control board 42. The 5V DC voltage (DC5VA) is also used as a voltage for generating various control signals.

[0163] [5.7 Backup power supply wiring] Fig. 19 is a composite diagram of the wiring pattern of the backup power supply (VBB). Fig. 19 is a composite diagram of the wiring pattern provided on the component side 42a shown in Fig. 7, the wiring pattern provided on the solder side 42b shown in Fig. 8, and the backup power supply wiring from the wiring pattern L5b_2 to the fourth pin and the sixth pin (CN3_4, CN3_6) of the connector CN3 among the electronic components arranged on the dispensing control board 42 shown in Fig. 9.

[0164] 7 to 9, 13, 14, and 19, one end of a wiring pattern L5b_3 on the solder surface 42b is connected to the other end of the wiring pattern L5b_2 via a noise removal filter FLT3. A backup power generation circuit 80 is connected to the middle of the wiring pattern L5b_3. The backup power generation circuit 80 includes a large-capacity electrolytic capacitor C13 and a diode D5. The anode terminal of the diode D5 is connected to the middle of the wiring pattern L5b_3, and the cathode terminal is connected to one end of the wiring pattern LVb_1 on the solder surface 42b. The electrolytic capacitor C13 is a two-terminal capacitor, with the positive terminal (lead pin) connected to the middle of the wiring pattern LVb_1 and the negative terminal (lead pin) connected to ground. Therefore, when a 5V DC voltage (DC5VA) is supplied to the electrolytic capacitor C13, it stores charge as a backup power supply (VBB), and when the supply of the 5V DC voltage (DC5VA) is stopped (when the power is turned off), it outputs the backup power supply (VBB) to the wiring pattern LVb_1.

[0165] One end of the wiring pattern LVb_2 is connected to the middle of the wiring pattern LVb_1 via a noise removal filter FLT4, and the other end of the wiring pattern LVb_2 is connected to the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3. As a result, the backup power supply VBB is output to the main control board 40 (RAM40c) via the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3 and the transmission line H2.

[0166] Furthermore, as will be described in detail later, one end of the wiring pattern LVa_1 on the component surface 42a is connected to the other end of the wiring pattern LVb_1 via a through hole TB_1, and the backup power supply (VBB) that passes through the wiring pattern LVa_1 is supplied to the integrated circuit IC7 (RAM).

[0167] [5.8 Power supply wiring for integrated circuit IC7] Fig. 20 is a composite diagram of the power supply wiring of the integrated circuit IC7. Fig. 20 is a composite diagram of the wiring pattern provided on the component side 42a shown in Fig. 7, the wiring pattern provided on the solder side 42b shown in Fig. 8, and the power supply wiring to the integrated circuit IC7 extracted from the electronic components arranged on the dispensing control board 42 shown in Fig. 9.

[0168] As shown in Figures 7 to 9, 15, and 20, one end of the wiring pattern L5a_2 on the component surface 42a is connected to the middle of the wiring pattern L5b_3 via a through hole T5_5, and the other end of the wiring pattern L5a_2 is connected to the middle of the wiring pattern L5b_4 on the solder surface 42b via a through hole T5_6.

[0169] One end of the wiring pattern L5b_4 is connected to one end of the wiring pattern L5a_3 on the component side 42a via a through hole T5_7, and one end of the wiring pattern L5a_3 is connected to one end of the wiring pattern L5b_5 on the solder side 42b via a through hole T5_8. The other end of the wiring pattern L5b_5 is connected to one end of the wiring pattern L5a_4 on the component side 42a via a through hole T5_9, and the other end of the wiring pattern L5a_4 is connected to the 52nd pin of the integrated circuit IC7.

[0170] The other end of the wiring pattern L5b_4 is connected to the middle of the wiring pattern L5a_5 on the component surface 42a via a through hole T5_10, and one end of the wiring pattern L5b_6 is connected to the middle of the wiring pattern L5a_5 via a through hole T5_11. The other end of the wiring pattern L5b_6 is connected to the 8th pin of the integrated circuit IC7.

[0171] One end of a wiring pattern L5b_7 on the solder surface 42b is connected to the middle of the wiring pattern L5a_5 via a through hole T5_12. One end of a wiring pattern L5a_6 on the component surface 42a is connected to the other end of the wiring pattern L5b_7 via a through hole T5_13. The other end of the wiring pattern L5a_6 is connected to the 19th pin of the integrated circuit IC7.

[0172] Therefore, a 5V DC voltage (DC5VA) is supplied to the integrated circuit IC7 from pins 8, 19, and 52.

[0173] Meanwhile, one end of the wiring pattern LVa_1 on the component side 42a is connected to the other end of the wiring pattern LVb_1 via a through hole TB_1, and one end of the wiring pattern LVa_1 is connected to one end of the wiring pattern LVb_3 on the solder side 42b via a through hole TB2. One end of the wiring pattern LVb_4 is connected to the other end of the wiring pattern LVb_3 via a resistor R22. The other end of the wiring pattern LVb_4 is connected to the 20th pin of the integrated circuit IC7. Therefore, the backup power supply (VBB) is supplied to the integrated circuit IC7 from the 20th pin.

[0174] The CPU of the integrated circuit IC7 operates on 5V DC voltage (DC5VA) supplied from pins 8, 19, and 52, and controls each part of the payout control board 42, the launcher 44, and the game ball payout device 46 by expanding the program stored in the ROM into the RAM and executing it. For example, the CPU instructs the launcher 44 on the firing strength and instructs the game ball payout device 46 to pay out game balls.

[0175] The RAM of the integrated circuit IC7 temporarily stores data for issuing instructions to each part of the payout control board 42, the launching device 44, and the game ball payout device 46.

[0176] When integrated circuit IC7 is cut off from the 5V DC voltage (DC5VA) supply due to a power outage, the CPU stops operating and the backup power supply (VBB) is supplied via pin 20. Then, in integrated circuit IC, the data stored in the RAM is backed up (retained) by the backup power supply (VBB).

[0177] <6. Configuration example> An example of the configuration of the gaming machine 1 will be described below.

[0178] The gaming machine 1 of the embodiment has the following (Configuration A1-1). (Configuration A1-1) The gaming machine 1 is a gaming machine having a circuit board, and the circuit board has an input connector to which a predetermined power supply voltage is input, a backup power generation circuit that generates backup power based on the predetermined power supply voltage, an output connector that outputs the backup power, a first wiring pattern that connects the terminal in the input connector to which the predetermined power supply voltage is input and the backup power generation circuit, and a second wiring pattern that connects the backup power generation circuit and the terminal in the output connector from which the backup power is output, and the second wiring pattern is configured to be shorter than the first wiring pattern.

[0179] In the case of this (Configuration A1-1) concept, the board corresponds to the dispensing control board 42, the predetermined power supply step-down corresponds to 5V DC voltage (DC5VA), the input connector corresponds to connector CN1, the backup power supply corresponds to backup power supply (VBB), the output connector corresponds to connector CN3, and the terminals at the input connector to which the predetermined power supply voltage is input correspond to pins 15 to 18 (CN1_15 to CN1_18) of connector CN3. Also, the first wiring pattern corresponds to wiring patterns L5b_1, L5a_1, L5b_3, and LVb_1, and the second wiring pattern corresponds to wiring patterns LVb_1 and LVb_2.

[0180] As shown in FIGS. 18 to 20, when a 5V DC voltage (DC5VA) is input to the 15th to 18th pins (CN1_15 to CN1_18) of the connector CN1, it passes through the wiring pattern L5b_1 on the solder surface 42b and is input to the two through holes T5_1 and T5_2. The 5V DC voltage (DC5VA) input to the two through holes T5_1 and T5_2 is guided to the component surface 42a side via the through holes T5_1 and T5_2, and then passes through the wiring pattern L5a_1 and is input to the two through holes T5_3 and T5_4. The 5V DC voltage (DC5VA) input to the two through holes T5_3 and T5_4 is guided to the solder surface 42b side via the through holes T5_3 and T5_4, and then passes through the wiring pattern L5b_2 and is input to the noise reduction filter FLT3. The 5V DC voltage (DC5VA) input to the noise removal filter FLT3 is input to the anode terminal of diode D5 of the backup power generation circuit 80, output from the cathode terminal, and input to the positive terminal of electrolytic capacitor C13 through wiring pattern LVb_1. The total length of the wiring pattern through which the 5V DC voltage (DC5VA) passes from pins 15 to 18 (CN1_15 to CN1_18) of connector CN1 to the backup power generation circuit 80 (diode D5) is approximately 290 mm.

[0181] 19, the backup power supply (VBB) is generated by the backup power supply generating circuit 80 based on a 5V DC voltage (DC5VA) and stored in the electrolytic capacitor C13. When the 5V DC voltage is no longer supplied to the positive terminal of the electrolytic capacitor C13 due to a power outage, the backup power supply (VBB) is input from the positive terminal of the electrolytic capacitor C13 through the wiring pattern LVb_1 on the solder surface 42b to the noise reduction filter FLT4. The backup power input to the noise reduction filter FLT4 is output from the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3 through the wiring pattern LVb_2 on the solder surface 42b via the noise reduction filter FLT4 to the main control board 40. The total length of the wiring pattern through which the backup power supply (VBB) passes from the electrolytic capacitor C13 to the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3 is approximately 56 mm.

[0182] Therefore, the total length (approximately 56 mm) of the wiring pattern through which the backup power supply (VBB) output to the main control board 40 passes is shorter than the total length (approximately 290 mm) of the wiring pattern through which the 5V DC voltage (DC5VA) input from the power supply board 70 passes. In this way, by making the wiring pattern of the backup power supply (VBB) output to the main control board 40 shorter than the wiring pattern through which the 5V DC voltage (DC5VA) input from the power supply board 70 passes, noise from the backup power supply (VBB) can be reduced and the stability of the backup of RAM 40c during a power outage can be improved.

[0183] 9, on the dispensing control board 42, the connectors CN1 and CN3 are arranged at positions spaced apart in the longitudinal direction (left-right direction), with the connector CN1 at the upper right and the connector CN3 at the upper left. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is arranged slightly above and to the left of the dispensing control board 42, in a position closer to the connector CN3 than the connector CN1 (directly below the connector CN3).

[0184] In this way, by arranging the backup power generation circuit 80 closer to the connector CN3 than to the connector CN1, it becomes possible to design the wiring patterns LVb_1 and LVb_2, through which the backup power supply (VBB) output to the main control board 40 passes, to be short on the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1 and LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, the effects of noise can be reduced and the stability of the backup of RAM 40c during a power outage can be improved.

[0185] Also, diode D5 is positioned closer to connector CN1 than electrolytic capacitor C13. Furthermore, diode D5 is positioned so that its anode terminal is closer to connector CN1 than its cathode terminal. This allows the dispensing control board 42 to shorten the wiring pattern when connecting pins 15 to 18 (CN1_15 to CN1_18) of connector CN1 to diode D5 that constitutes backup power generation circuit 80, thereby reducing the impact of noise on the wiring pattern through which 5V DC voltage (DC5VA) passes.

[0186] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A1-2) in addition to (Configuration A1-1). (Configuration A1-2) The substrate includes a control circuit to which a backup power supply is input, and a third wiring pattern that connects the backup power supply generating circuit and the control circuit, and the second wiring pattern is configured to be shorter than the third wiring pattern.

[0187] In the case of this (configuration A1-2) concept, the control circuit corresponds to the integrated circuit IC7, and the third wiring pattern corresponds to the wiring patterns LVb_1, LVa_1, LVB_3, and LVb_4.

[0188] As shown in FIG. 20, when a power outage occurs and 5V DC voltage is no longer supplied to the positive terminal of electrolytic capacitor C13, the backup power supply (VBB) is input from the positive terminal of electrolytic capacitor C13 to through-hole TB_1 through wiring pattern LVb_1 on solder surface 42b. The backup power supply (VBB) input to through-hole TB_1 is guided to the component surface 42a via through-hole TB_1 and then input to resistor R22 through wiring pattern LVa_1. The backup power supply (VBB) input to resistor R22 is then input to pin 20 of integrated circuit IC7 through resistor R22 and wiring pattern LVb_4. The total length of the wiring pattern through which the backup power supply (VBB) passes from electrolytic capacitor C13 to pin 20 of integrated circuit IC7 is approximately 228 mm.

[0189] Therefore, the total length (approximately 56 mm) of the wiring pattern through which the backup power supply (VBB) output to the main control board 40 passes is shorter than the total length (approximately 228 mm) of the wiring pattern through which the backup power supply (VBB) input to the integrated circuit IC7 passes. By shortening the wiring pattern of the backup power supply (VBB) output to the main control board 40 in this way, it is possible to reduce noise entering the backup power supply (VBB) output to the main control board 40 and ensure that RAM 40c is backed up when the power is turned off.

[0190] 9, the integrated circuit IC7 is disposed slightly below and to the left of the dispensing control board 42. The backup power generation circuit 80 is disposed closer to the connector CN3 than the integrated circuit IC7.

[0191] In this way, by arranging the backup power generation circuit 80 closer to the connector CN3 than the integrated circuit IC7, it is possible to design the wiring patterns LVb_1 and LVb_2, through which the backup power supply (VBB) output to the main control board 40 passes, to be short on the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1 and LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, the effects of noise can be reduced and the stability of the backup of RAM 40c can be more reliably achieved when the power is cut off.

[0192] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A1-3) in addition to (Configuration A1-1) and (Configuration A1-2). (Configuration A1-3) The gaming machine 1 is configured such that the output connector outputs a predetermined power supply voltage and a backup power supply.

[0193] In the case of this (configuration A1-3) concept, the connector CN3, which is an output connector, outputs a 5V DC voltage (DC5VA) and a backup power supply (VBB) to the main control board 40. That is, the 5V DC voltage (DC5VA) input from the power supply board 70 is branched by the wiring pattern L5b_2, one branch is supplied directly to the 10th and 12th pins (CN3_10, CN3_12) of the connector CN3 and output to the main control board 40, and the other branch is supplied to the backup power supply generation circuit 80 to generate backup power (see FIG. 19).

[0194] In this case, one branch of the 5V DC voltage (DC5VA) is supplied to the connector CN3, and the other is supplied to the backup power generation circuit 80, so that the 5V DC voltage (DC5VA) can be branched near the connector CN3. Therefore, the wiring pattern (L5b_2) after branching can be shortened, and the wiring can be simplified.

[0195] The gaming machine 1 of the embodiment has the following (Configuration A2-1). (Configuration A2-1) The gaming machine 1 is a gaming machine having a circuit board, the circuit board having an input connector to which a predetermined power supply voltage is input, a backup power generation circuit that generates backup power based on the predetermined power supply voltage, a control circuit to which the backup power is input, a first wiring pattern that connects the terminal in the input connector to which the predetermined power supply voltage is input and the backup power generation circuit, and a second wiring pattern that connects the backup power generation circuit and the control circuit, the second wiring pattern being shorter than the first wiring pattern.

[0196] In the case of this (Configuration A2-1) concept, the board corresponds to the dispensing control board 42, the predetermined power supply step-down corresponds to 5V DC voltage (DC5VA), the input connector corresponds to the connector CN1, the backup power supply corresponds to the backup power supply (VBB), the backup power supply generating circuit corresponds to the backup power supply generating circuit 80, and the control circuit corresponds to the integrated circuit IC7. Also, the first wiring pattern corresponds to the wiring patterns L5b_1, L5a_1, L5b_3, and LVb_1, and the second wiring pattern corresponds to the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4.

[0197] As described above, the total length of the wiring pattern input from the main control board 40 to the backup power generation circuit 80, i.e., the total length of the wiring pattern through which the 5V DC voltage (DC5VA) passes from the 15th to 18th pins (CN1_15 to CN1_18) of the connector CN1 to the backup power generation circuit 80 (diode D5), is approximately 290 mm.

[0198] Furthermore, when the 5V DC voltage is no longer supplied to the positive terminal of electrolytic capacitor C13 due to a power outage, the backup power supply (VBB) is input from the positive terminal of electrolytic capacitor C13 through wiring pattern LVb_1 on solder surface 42b to through-hole TB_1. The backup power supply (VBB) input to through-hole TB_1 is led to the component side 42a via through-hole TB_1 and then through wiring pattern LVa_1 to through-hole TB_2. The backup power supply (VBB) input to through-hole TB_2 is led to the solder side 42b via through-hole TB_2 and then through wiring pattern LVb_3 to resistor R22. The backup power supply (VBB) input to resistor R22 is then passed through resistor R22 and wiring pattern LVb_4 to pin 20 of integrated circuit IC7. The total length of the wiring pattern through which the backup power supply (VBB) passes from electrolytic capacitor C13 to pin 20 of integrated circuit IC7 is approximately 228 mm.

[0199] Therefore, the total length (approximately 228 mm) of the wiring pattern through which the backup power supply (VBB) input to integrated circuit IC7 passes is shorter than the total length (approximately 290 mm) of the wiring pattern through which the 5V DC voltage (DC5VA) input from power supply board 70 to backup power generation circuit 80 passes. In this way, by making the wiring pattern of the backup power supply (VBB) input to integrated circuit IC7 shorter than the wiring pattern through which the 5V DC voltage (DC5VA) input from power supply board 70 to backup power generation circuit 80 passes, it is possible to reduce noise entering the backup power supply (VBB) and improve the stability of the backup of RAM in integrated circuit IC7 when power is interrupted.

[0200] 9, on the dispensing control board 42, the connector CN1 is arranged at the top right, the backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is arranged slightly above on the left side, and the integrated circuit IC7 is arranged slightly below on the left side. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is arranged closer to the integrated circuit IC7 than the connector CN1.

[0201] In this way, by arranging the backup power generation circuit 80 closer to the integrated circuit IC7 than the connector CN1, it is possible to design short wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4 through which the backup power (VBB) input to the integrated circuit IC7 passes on the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4 through which the backup power (VBB) input to the integrated circuit IC7 passes, the effects of noise can be reduced and the stability of the backup of the RAM of the integrated circuit IC7 during a power outage can be improved.

[0202] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A2-2) in addition to (Configuration A2-1). (Configuration A2-2) First and second power supply voltages having different voltages are input to the input connector, and the board generates a third power supply voltage having the same voltage as the first power supply voltage based on the second power supply voltage, and the backup power generation circuit is configured to generate backup power based on the first power supply voltage.

[0203] In this (Configuration A2-2) approach, the first power supply voltage corresponds to a 5V DC voltage (DC5VA), the second power supply voltage corresponds to a 12V DC voltage (DC12VA), and the third power supply voltage corresponds to a 5V DC voltage (DC5VH).

[0204] Here, the 5V DC voltage (DC5VA) is supplied to the main control board 40, and is also supplied to components directly involved in game control, such as for generating various control signals such as a reset signal. On the other hand, the 5V DC voltage (DC5VH) is supplied to components not directly involved in game control (components involved in firing), such as the handle volume and touch sensor.

[0205] Therefore, the 5V DC voltage (DC5VA) generated by the power supply board 70 realizes stable control of the components directly involved in game control, and the 5V DC voltage (DC5VH) generated by the payout control board 42 operates the components not directly involved in game control. This reduces the impact on the components directly involved in control by the operating voltage supplied to the components not directly involved in game control.

[0206] The gaming machine 1 of the embodiment has the following (Configuration A3-1). (Configuration A3-1) The gaming machine 1 is a gaming machine having a circuit board, the circuit board having a backup power generation circuit that generates backup power based on a predetermined power supply voltage, an output connector that outputs the backup power, a control circuit to which the backup power is input, a first wiring pattern that connects the backup power generation circuit to the terminal in the output connector from which the backup power is output, and a second wiring pattern that connects the backup power generation circuit to the control circuit, the first wiring pattern being shorter than the second wiring pattern.

[0207] In the case of this (Configuration A3-1) concept, the board corresponds to the dispensing control board 42, the predetermined power supply step-down corresponds to 5V DC voltage (DC5VA), the backup power supply corresponds to the backup power supply (VBB), the output connector corresponds to the connector CN3, the backup power supply generating circuit corresponds to the backup power supply generating circuit 80, and the control circuit corresponds to the integrated circuit IC7. Also, the first wiring pattern corresponds to the wiring patterns LVb_1 and LVb_2, and the second wiring pattern corresponds to the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4.

[0208] As described above, the total length of the wiring pattern through which the backup power supply (VBB) output to the main control board 40 passes is approximately 56 mm, which is shorter than the total length (approximately 228 mm) of the wiring pattern through which the backup power supply (VBB) supplied to the integrated circuit IC7 passes. In this way, by shortening the wiring pattern of the backup power supply (VBB) output to the main control board 40, it is possible to reduce noise input to the backup power supply (VBB) output to the main control board 40 and improve the stability of the backup of RAM 40c when the power is cut off.

[0209] 9, on the dispensing control board 42, the connector CN3 is arranged at the upper left, the backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is arranged slightly above on the left, and the integrated circuit IC7 is arranged slightly below on the left. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is arranged in a position closer to the connector CN3 than the integrated circuit IC7 (directly below the connector CN3).

[0210] In this way, by arranging the backup power generation circuit 80 closer to the connector CN3 than the integrated circuit IC7, it is possible to design the wiring patterns LVb_1 and LVb_2, through which the backup power supply (VBB) output to the main control board 40 passes, to be short on the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1 and LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, the effects of noise can be reduced and the stability of the backup of RAM 40c during a power outage can be improved.

[0211] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A3-2) in addition to (Configuration A3-1). (Configuration A3-2) The substrate includes an input connector to which a predetermined power supply voltage is input, and a third wiring pattern that connects the terminal in the input connector to which the predetermined power supply voltage is input and the backup power generation circuit, and the third wiring pattern is configured to be longer than the second wiring pattern.

[0212] In the case of this (configuration A3-2) concept, the input connector corresponds to the connector CN1, and the third wiring pattern corresponds to the wiring patterns L5b_1, L5a_1, L5b_2, L5b_3, and LVb_1.

[0213] As described above, the length of the wiring pattern from connector CN1 to electrolytic capacitor C13 is approximately 290 mm, which is longer than the total length (approximately 228 mm) of the wiring patterns through which the backup power supply (VBB) supplied to integrated circuit IC7 passes. By shortening the wiring pattern of the backup power supply (VBB) input to integrated circuit IC7 in this way, it is possible to reduce noise entering the backup power supply (VBB) input to integrated circuit IC7 and improve the stability of the backup of the RAM of integrated circuit IC7.

[0214] 9, the connector CN1 is located at the upper right of the dispensing control board 42. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is located closer to the integrated circuit IC7 than the connector CN1.

[0215] In this way, by arranging the backup power generation circuit 80 closer to the integrated circuit IC7 than the connector CN1, it is possible to design short wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4 through which the backup power (VBB) input to the integrated circuit IC7 passes on the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4 through which the backup power (VBB) input to the integrated circuit IC7 passes, the effects of noise can be reduced and the stability of the backup of the RAM of the integrated circuit IC7 during a power outage can be improved.

[0216] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A3-3) in addition to (Configuration A3-1) and (Configuration A3-2). (Configuration A3-3) The backup power generation circuit includes a diode and a capacitor. In the case of this (Configuration A3-3) concept, the diode corresponds to the diode D5, and the capacitor corresponds to the electrolytic capacitor C13.

[0217] As a result, by using an electrolytic capacitor C13 that can be charged and whose performance does not change, instead of electronic components such as batteries that may not be able to restore the original state if they deteriorate, as the electronic component that generates the backup power supply (VBB), the stability of the RAM backup of RAM40c and integrated circuit IC7, which affect game play and ball output, can be further improved.

[0218] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A3-4) in addition to (Configuration A3-1) to (Configuration A3-3). (Configuration A3-4) The diode is configured to prevent reverse current from flowing through the backup power supply.

[0219] This makes it possible, with a simple configuration, to prevent the backup power supply (VBB) from flowing back into the wiring pattern of the 5V DC voltage (DC5VA) and affecting electronic components that operate on the 5V DC voltage (DC5VA).It also makes it possible to prevent the supply of the backup power supply (VBB) from reducing the backup time of the RAM 40c and the RAM of the integrated circuit IC7.

[0220] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A3-5) in addition to (Configuration A3-3) to (Configuration A3-4). (Configuration A3-5) The diode is configured so that its cathode terminal is closer to the positive terminal of the capacitor than its anode terminal.

[0221] 9, diode D5 is arranged so that its cathode terminal is closer to the positive terminal of electrolytic capacitor C13 than its anode terminal. Furthermore, electrolytic capacitor C13 is arranged so that its positive terminal is closer to the cathode terminal of diode D5 than its negative terminal. In other words, the electronic components are arranged on dispensing control board 42 so that the distance between the positive terminal of electrolytic capacitor C13 and the cathode terminal of diode D5 is shorter than the distance between the negative terminal of electrolytic capacitor C13 and the cathode terminal of diode D5.

[0222] This allows the wiring pattern to be shortened when connecting electrolytic capacitor C13 and diode D5 that make up backup power supply generating circuit 80 on dispensing control board 42, further reducing the effects of noise.

[0223] The gaming machine 1 of the embodiment has the following (Configuration B1-1). (Configuration B1-1) The gaming machine 1 is a gaming machine equipped with a circuit board, and the circuit board is supplied with a predetermined power supply voltage and is equipped with a plurality of power lines with different maximum current capacities, and one or more through holes that connect the power lines formed on different layers of the circuit board, and the power line with a larger maximum current capacity is configured to be connected to a larger number of through holes than the power line with a smaller maximum current capacity.

[0224] In the case of this (configuration B1-1) concept, the board corresponds to the dispensing control board 42. Furthermore, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9, the combination of the wiring patterns L12a_2, L12b_2 and the through holes T12_10 to T12_15, and the combination of the wiring patterns L35a_1, L35b_2 and the through holes T35_5 to T35_8.

[0225] Fig. 21 is a diagram illustrating the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Fig. 21, the wiring patterns L12b_1 and L12a_1 are supplied with a 12V DC voltage (DC12VA), have a line width (hereinafter simply referred to as width) of 5mm, and have a maximum current capacity set to 5.0A. Furthermore, the wiring patterns L12b_1 and L12a_1 are connected via nine through holes (T12_1 to T12_9), and the nine through holes (T12_1 to T12_9) have a diameter of 0.5mm.

[0226] The wiring patterns L12a_2 and L12b_2 are supplied with a direct current voltage of 12 V (DC12VA), have a width of 3 mm, and have a maximum current capacity of 3.0 A. The wiring patterns L12a_2 and L12b_2 are connected via six through holes (T12_10 to T12_15), each having a diameter of 0.5 mm.

[0227] Furthermore, wiring patterns L35a_1 and L35b_2 are supplied with a direct current voltage of 35 V (DC35VA), have a width of 2 mm, and have a maximum current capacity set to 1.3 A. Furthermore, wiring patterns L35a_1 and L35b_2 are connected via two through holes (T35_1 to T35_2), and the two through holes (T35_1 to T35_2) have a diameter of 0.5 mm.

[0228] Therefore, a combination of wiring patterns with a large maximum current capacity has a larger number of connected through holes than a combination of wiring patterns with a small maximum current capacity.

[0229] In this way, by increasing the number of through holes connected to a combination of wiring patterns with a larger maximum current capacity, the electrical resistance in the through holes when current flows through a wiring pattern with a large current amount can be reduced, and heat generation can be suppressed.

[0230] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration B1-2) in addition to (Configuration B1-1). (Configuration B1-2) The plurality of power supply lines are configured to receive power supply voltages having different voltage values.

[0231] For example, different power supply voltages (DC12VA, DC35VA) are supplied to the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9 and the combination of the wiring patterns L35a_1, L35b_1 and the through holes T35_5 to T35_8 shown in FIG.

[0232] In this way, even if the supplied power supply voltages are different, the larger the maximum current capacity of a combination of wiring patterns, the more through holes are connected, thereby reducing the electrical resistance in the through holes when current flows through a wiring pattern with a large current amount, and suppressing heat generation.

[0233] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration B1-3) in addition to (Configuration B1-1) and (Configuration B1-2). (Configuration B1-3) A power supply line with a large maximum current capacity is configured to be wider than a power supply line with a small maximum current capacity.

[0234] As shown in FIG. 21, the larger the maximum current capacity of a wiring pattern, the wider the width of the wiring pattern.

[0235] In this way, by making the width of the wiring pattern wider for a combination of wiring patterns with a larger maximum current capacity, the electrical resistance when a current flows through the wiring pattern with a large current amount can be reduced, and heat generation can be suppressed.

[0236] The gaming machine 1 of the embodiment has the following (Configuration B2-1). (Configuration B2-1) The gaming machine 1 is a gaming machine that includes a circuit board, and the circuit board includes one or more power lines that are supplied with a predetermined power supply voltage and have different maximum current capacities, and multiple through holes that connect the power supply lines formed on different layers of the board, and the power supply lines that have the same power supply voltage but different maximum current capacities are configured to be connected to different numbers of through holes.

[0237] In the case of this (configuration B2-1) concept, the board corresponds to the dispensing control board 42. Furthermore, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9, and the combination of the wiring patterns L12a_2, L12b_2 and the through holes T12_10 to T12_15.

[0238] Fig. 22 is a diagram illustrating the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Fig. 22, the wiring patterns L12b_1 and L12a_1 are supplied with a 12V direct current voltage (DC12VA), have a width of 5 mm, and have a maximum current capacity set to 5.0 A. Furthermore, the wiring patterns L12b_1 and L12a_1 are connected via nine through holes (T12_1 to T12_9), and the nine through holes (T12_1 to T12_9) have a diameter of 0.5 mm.

[0239] The wiring patterns L12a_2 and L12b_2 are supplied with a direct current voltage of 12 V (DC12VA), are 3 mm wide, and have a maximum current capacity of 3.0 A. The wiring patterns L12a_2 and L12b_2 are connected via six through holes (T12_10 to T12_15), each with a diameter of 0.5 mm.

[0240] Therefore, even when the same power supply voltage is supplied to a combination of wiring patterns, if the maximum current capacity differs, the number of connected through holes will also differ.

[0241] In this way, even when the combination of wiring patterns is supplied with the same power supply voltage, if the maximum current capacity is different, the number of connected through holes can be varied to reduce the electrical resistance in the through holes when current flows through a wiring pattern with a large current amount, thereby suppressing heat generation.

[0242] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration B2-2) in addition to (Configuration B2-1). (Configuration B2-2) A power supply line having a larger maximum current capacity at the same power supply voltage is configured to be wider than a power supply line having a smaller maximum current capacity.

[0243] As shown in FIG. 22, even if the power supply voltage is the same (DC 12VA), the width of the wiring pattern increases as the maximum current capacity increases.

[0244] In this way, even if the power supply voltage is the same, the wider the wiring pattern width is, the larger the maximum current capacity of the combination of wiring patterns is, thereby reducing the electrical resistance when current flows through the wiring pattern with a large current amount and suppressing heat generation.

[0245] The gaming machine 1 of the embodiment has the following (Configuration B3-1). (Configuration B3-1) The gaming machine 1 is a gaming machine that includes a circuit board, and the circuit board includes a power line to which a predetermined power supply voltage is supplied and one or more through holes that connect the power lines formed on different layers of the board, and the power line may branch into multiple lines, with the number of through holes connected to the power line before branching being greater than the number of through holes connected to the power line after branching.

[0246] In the case of this (configuration B3-1) concept, the board corresponds to the dispensing control board 42. The power supply lines before branching and the through holes connecting the power supply lines correspond to the combination of the wiring pattern L12a_1 and the through holes T12_1 to T12_9. The power supply lines after branching and the through holes connecting the power supply lines correspond to the combination of the wiring pattern L12a_2 and the through holes T12_10 to T12_15. As described above, the wiring pattern L12a_1 branches into the wiring patterns L12a_2 and L12a_3 along the way.

[0247] 22, the wiring pattern L12a_1 before branching is supplied with a direct current voltage of 12 V (DC12VA), has a width of 5 mm, and has a maximum current capacity set to 5.0 A. Furthermore, the wiring pattern L12a_1 before branching is connected via nine through holes (T12_1 to T12_9), and the nine through holes (T12_1 to T12_9) have a diameter of 0.5 mm.

[0248] Furthermore, the branched wiring pattern L12a_2 is supplied with a direct current voltage of 12 V (DC12VA), has a width of 3 mm, and has a maximum current capacity set to 3.0 A. Furthermore, the branched wiring pattern L12a_2 is connected via six through holes (T12_10 to T12_15), and the six through holes (T12_10 to T12_15) have a diameter of 0.5 mm.

[0249] Therefore, the number of through holes (9) connected to the wiring pattern L12a_1 before branching is greater than the number of through holes (6) connected to the wiring pattern L12a_2 after branching. Also, the wiring pattern L12a_1 before branching has a greater maximum current capacity than the wiring pattern L12a_2 after branching.

[0250] In this way, by making the number of through holes connected to the wiring pattern L12a_1 before branching greater than the number of through holes connected to the wiring pattern L12a_2 after branching, the electrical resistance in the through holes when current flows through a wiring pattern with a large current amount can be reduced, and heat generation can be suppressed.

[0251] Furthermore, the gaming machine 1 of the embodiment has the following (Configuration B3-2) in addition to (Configuration B3-1). (Configuration B3-2) The power line before the branch is configured to be wider than the power line after the branch.

[0252] The width (5 mm) of the wiring pattern L12a_1 before branching is wider than the width (3 mm) of the power supply line after branching. By making the width of the wiring pattern L12a_1 before branching wider than the power supply line after branching, electrical resistance can be reduced when a current flows through a wiring pattern with a large current amount, and heat generation can be suppressed.

[0253] The gaming machine 1 of the embodiment has the following (Configuration B4-1). (Configuration B4-1) The gaming machine 1 is a gaming machine equipped with a circuit board, and the circuit board has a plurality of power lines to which a predetermined power supply voltage is supplied, and one or more through holes that connect the power lines formed on different layers of the circuit board, and a power line connected to a smaller number of through holes is configured to be connected to a through hole with a larger diameter than a power line connected to a larger number of through holes.

[0254] In the case of this (configuration B4-1) concept, the board corresponds to the dispensing control board 42. Furthermore, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L5b_1, L5a_1 and the through holes T5_1 to T5_2, and the combination of the wiring patterns L35a_1, L35b_2 and the through holes T35_5 to T35_8.

[0255] Fig. 23 is a diagram illustrating the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Fig. 23, the wiring patterns L5b_1 and L5a_1 are supplied with a direct current voltage of 5V (DC5VA), have a width of 3 mm, and have a maximum current capacity set to 2.5 A. The wiring patterns L5b_1 and L5a_1 are connected via two through holes (T5_1 and T5_2), and the diameter of the two through holes (T5_1 and T5_2) is 0.8 mm.

[0256] Furthermore, wiring patterns L35a_1 and L35b_2 are supplied with a direct current voltage of 35 V (DC35VA), have a width of 2 mm, and have a maximum current capacity set to 1.3 A. Furthermore, wiring patterns L35b_1 and L35a_1 are connected via four through holes (T35_1 to T35_4), and the four through holes (T35_1 to T35_2) have a diameter of 0.5 mm.

[0257] Therefore, the wiring patterns L5b_1 and L5a_1, which are connected to a smaller number of through holes, are connected to through holes with a larger diameter (0.8 mm diameter through holes) than the wiring patterns L35a_1 and L35b_2, which are connected to a larger number of through holes.

[0258] This means that when there are a small number of connected through holes and there is a risk that a large amount of current will flow through one through hole, the diameter of the through hole can be increased to reduce the electrical resistance in the through hole and suppress heat generation.

[0259] The gaming machine 1 of the embodiment has the following (Configuration B5-1). (Configuration B5-1) The gaming machine 1 is a gaming machine equipped with a circuit board, the circuit board being supplied with a predetermined power supply voltage and equipped with one or more power lines with different maximum current capacities, and a plurality of through holes that connect the power lines formed on different layers of the circuit board, and the through holes are connected so that the product of the diameter and number of the through holes is larger for power lines with larger maximum current capacities than for power lines with smaller maximum current capacities.

[0260] In the case of this (configuration B5-1) concept, the board corresponds to the dispensing control board 42. Furthermore, the power supply lines and the through holes connecting the power supply lines correspond to combinations of wiring patterns L12b_1, L12a_1 and through holes T12_1 to T12_9, combinations of wiring patterns L12a_2, L12b_2 and through holes T12_10 to T5_15, and combinations of wiring patterns L5b_1, L5a_1 and through holes T5_1 to T5_2.

[0261] Fig. 24 is a diagram illustrating the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Fig. 24, the wiring patterns L12b_1 and L12a_1 are supplied with a 12V DC voltage (DC12VA), are 5mm wide, and have a maximum current capacity set to 5.0A. The wiring patterns L12b_1 and L12a_1 are connected via nine through holes (T12_1 to T12_9), and the nine through holes (T12_1 to T12_9) have a diameter of 0.5mm. Therefore, in this case, the product of the diameter and the number of through holes is 4.5.

[0262] The wiring patterns L12a_2 and L12b_2 are supplied with a 12V DC voltage (DC12VA), are 3mm wide, and have a maximum current capacity of 3.0A. The wiring patterns L12a_2 and L12b_2 are connected via six through holes (T12_10 to T12_15), each with a diameter of 0.5mm. Therefore, in this case, the product of the diameter and the number of through holes is 3.0.

[0263] The wiring patterns L5b_1 and L5a_1 are supplied with a 5V DC voltage (DC5VA), are 3mm wide, and have a maximum current capacity of 2.5A. The wiring patterns L5b_1 and L5a_1 are connected via two through holes (T5_1 and T5_2), each with a diameter of 0.8mm. Therefore, in this case, the product of the diameter and the number of through holes is 1.6.

[0264] In this way, a wiring pattern with a large maximum current capacity is connected to through holes with a larger product of the diameter and number of through holes than a wiring pattern with a small maximum current capacity.

[0265] As a result, in a wiring pattern with a large maximum current capacity, the total surface area of ​​the through holes can be increased, the electrical resistance in the through holes can be reduced, and heat generation can be suppressed.

[0266] The gaming machine 1 of the embodiment has the following (configuration C1-1). (Configuration C1-1) The gaming machine 1 has a substrate that is supplied with a predetermined power supply voltage and has multiple power lines with different maximum current capacities, and one or more vias that connect the power lines formed on different layers of the substrate, and is configured so that the number of vias connected by the power lines varies.

[0267] In the case of this (configuration C1-1) concept, the board corresponds to the dispensing control board 42. Furthermore, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9, the combination of the wiring patterns L12a_2, L12b_2 and the through holes T12_10 to T12_15, and the combination of the wiring patterns L35a_1, L35b_2 and the through holes T35_1 to T35_4.

[0268] For example, as shown in Figure 21, the number of through holes connected varies depending on the wiring pattern, so when a current flows through a wiring pattern with a large current amount, the electrical resistance can be reduced and heat generation can be suppressed.

[0269] The above describes the embodiments, but each of the configuration examples from (Configuration A1-1) to (Configuration C1-1) above can be combined in various ways, and by combining them in any way, it is possible to create a gaming machine 1 that combines the effects described for each configuration. In addition, it is possible to combine the configurations and operations described in the embodiments. Furthermore, the various specific examples given are merely one way of realizing each configuration, and various specific examples that are not specifically shown are also possible. Furthermore, although the embodiment has been described using a pachinko gaming machine, the present invention can also be applied to reel-type gaming machines such as so-called slot gaming machines. In such a slot machine, the board configuration, circuit configuration, connector configuration, power supply configuration, etc., as explained in each embodiment can also be adopted.

[0270] The present invention can also be applied to a controlled gaming machine in which gaming balls circulate within the gaming machine 1. In the case of a controlled gaming machine, there is no need to supply AC input power (24V AC) to the gaming ball dispensing device connection terminal board 71. As shown in Figure 6, there is no need to branch the transmission line H1. However, if the power supply board 70 is also changed to stop supplying AC input power (24V AC) to the gaming ball dispensing device connection terminal board 71, it is necessary to redesign the new power supply board 70, and it is not possible to reuse the existing power supply board 70.

[0271] Therefore, in the controlled gaming machine, as shown in Figures 25 to 28, AC input power (AC 24V) is input from pins 25 and 26 of connector CN1 of payout control board 42, and LED1 is turned on via bridge circuit DB1 and resistor R1. By doing so, it becomes possible to use the same power supply board 70 as in the gaming machine 1 of the embodiment. This makes it possible to omit a new design and also to reuse the power supply board 70 that has been used up until now.

[0272] Also, in the embodiment, a predetermined power supply voltage (for example, 5V DC voltage (DC5VA)) is input from the power supply board 70 to the connector CN1 (input connector) of the dispensing control board 42. However, the supply source board that inputs the predetermined power supply voltage to the input connector is not limited to this, and may be a relay board provided between the power supply boards 70, or may be another board.

[0273] Also, in the embodiment, at least one of a predetermined power supply voltage (for example, 5V DC voltage (DC5VA)) and a backup power supply (in the embodiment, both) is output from connector CN3 (output connector) of payout control board 42 to main control board 40. However, the supply destination board that outputs at least one of the predetermined power supply voltage and the backup power supply is not limited to this, and may be, for example, a board such as performance control board 41 or launch control board 45.
