[0009] The following describes a slot machine according to an embodiment of the gaming machine of the present invention, using Figures 1 to 26. In the event of any overlap in terminology with other embodiments, the terminology of this embodiment shall take precedence, and in the event of any overlap in descriptions with drawings other than Figures 1 to 26, the descriptions in Figures 1 to 26 shall take precedence.

[0010] The slot machine of this embodiment, described below, is a gaming machine that proceeds through a series of games in which a predetermined number of game tokens are inserted, and multiple reels, each decorated with multiple types of symbols, start to rotate when a predetermined rotation start instruction operation is received, and the success or failure of internal winnings of multiple types of roles is determined by lottery based on the reception of the rotation start instruction operation, and each of the multiple reels stops rotating individually when a predetermined rotation stop instruction operation is received, and if the conditions determined by the role based on the result of the lottery and the combination of symbols when the multiple reels stop match predetermined payout conditions, game tokens are paid out and the game ends, and if they do not match, the game ends without paying out game tokens.

[0011] First, the basic configuration of the slot machine 100 will be explained using Figures 1 and 2. Figure 1 is an external perspective view of the slot machine 100 as seen from the front (player side). Figure 2 is a diagram showing an example of a winning line.

[0012] The slot machine 100 shown in Figure 1 is an example of a gaming machine according to the present invention, and comprises a main body 101 and a front door 102 attached to the front side of the main body 101 and which can be opened and closed relative to the main body 101. Inside the center of the main body 101 (not shown), there are three reels (left reel 110, middle reel 111, right reel 112) with multiple types of symbols arranged on their outer surfaces, and are configured to rotate inside the slot machine 100. These reels 110 to 112 are driven to rotate by a drive device such as a stepping motor.

[0013] In this embodiment, each pattern is printed at equal intervals in appropriate numbers on a strip-shaped member, and this strip-shaped member is attached to a predetermined circular cylindrical frame material to constitute each reel 110 to 112. From the player's perspective, approximately three patterns are displayed vertically from the display window 113 on the reels 110 to 112, so that a total of nine patterns are visible. To explain in detail using Figure 2, the pattern displayed on the upper part of the left reel 110 (position 1 in the figure) is the left reel upper pattern, the pattern displayed on the middle part of the left reel 110 (position 2 in the figure) is the left reel middle pattern, the pattern displayed on the lower part of the left reel 110 (position 3 in the figure) is the left reel lower pattern, the pattern displayed on the upper part of the middle reel 111 (position 4 in the figure) is the middle reel upper pattern, the pattern displayed on the middle part of the left reel 111 (position 5 in the figure) is the middle reel middle pattern, and the pattern on the lower part of the middle reel 111 is the middle reel upper pattern. The symbols displayed on the first row (position 6 in the diagram) are called the lower row symbols of the middle reel, the symbols displayed on the upper row of the right reel 112 (position 7 in the diagram) are called the upper row symbols of the right reel, the symbols displayed on the middle row of the right reel 112 (position 8 in the diagram) are called the middle row symbols of the right reel, and the symbols displayed on the lower row of the right reel 112 (position 9 in the diagram) are called the lower row symbols of the right reel. Each of the symbols on each reel 110 to 112 is displayed vertically in groups of three, for a total of nine symbols, through the display window 113. By rotating each of the reels 110 to 112, the combination of symbols visible to the player changes. In other words, each of the reels 110 to 112 functions as a display device that can display multiple combinations of symbols in a variable manner. In addition to reels, other electronic image display devices such as liquid crystal displays can also be used as such display devices. Furthermore, in this embodiment, three reels are provided inside the center of the slot machine 100, but the number of reels and their installation positions are not limited to this.

[0014] A backlight (not shown) is positioned on the back of each reel 110 to 112 to illuminate the individual symbols displayed in the display window 113. It is desirable that the backlight be shielded for each symbol so that each symbol is illuminated evenly. Inside the slot machine 100, an optical sensor (not shown) consisting of a light-emitting part and a light-receiving part is provided near each reel 110 to 112, and a light-shielding piece of a certain length provided on the reel passes between the light-emitting part and the light-receiving part of this optical sensor. Based on the detection result of this optical sensor, the rotational position of the symbols on the reels is determined, and the reels 110 to 112 are stopped so that the target symbol is displayed on the winning line.

[0015] The winning line indicator lamp 120 is a lamp that indicates an active winning line. A winning line is a line on which it is determined whether or not a combination of symbols corresponding to a winning combination has been displayed. In this embodiment, only one line is provided, the middle winning line L1, which consists of the middle symbols on the left reel, the middle symbols on the middle reel, and the middle symbols on the right reel. Figure 2 shows this winning line L1. The active winning lines (hereinafter sometimes simply referred to as "active lines") are predetermined by the number of tokens bet as the game medium. The slot machine 100 shown in Figure 1 requires 3 tokens, and when the number of tokens inserted is less than 3, none of the winning lines are active. When 3 tokens are bet, winning line L1 becomes active. When a winning line becomes active, the game can be started by operating the start lever 135. Note that the number of winning lines is not limited to one line. For example, in addition to the middle winning line L1, a total of three lines may be set as valid winning lines: a diagonal winning line consisting of the upper symbol on the left reel, the middle symbol on the middle reel, and the lower symbol on the right reel; and an upward winning line consisting of the lower symbol on the left reel, the middle symbol on the middle reel, and the upper symbol on the right reel. Alternatively, a number of winning lines corresponding to the number of bets may be set as valid winning lines.

[0016] The notification lamp 123 is a lamp that informs the player, for example, that they have internally won a specific winning combination in the internal lottery described later, or that they are in a specific game state. The coin insertion lamp 124 is a lamp that informs the player that they can insert coins. The replay lamp 122 is a lamp that informs the player that they can replay the game (no need to insert coins) if they won a replay combination, which is one of the winning combinations, in the previous game. The reel panel lamp 128 is a lamp for visual effects.

[0017] The bet buttons 130 to 132 are buttons for inserting a predetermined number of tokens (called credits) electronically stored in the slot machine 100. In this embodiment, one token is inserted each time bet button 130 is pressed, two tokens are inserted when bet button 131 is pressed, and three tokens are inserted when bet button 132 is pressed. Hereinafter, bet button 132 will also be called the MAX bet button. The game token insertion lamp 129 lights up a number of lamps corresponding to the number of tokens inserted, and when the predetermined number of tokens has been inserted, the game start lamp 121 lights up to indicate that the game can be started.

[0018] The medal slot 141 is where the player inserts medals to start playing. That is, medals can be inserted electronically using the bet buttons 130 to 132, or by actually inserting medals into the medal slot 141 (insertion operation). Insertion includes both methods.

[0019] The stored tokens indicator 125 is a display for showing the number of tokens electronically stored in the slot machine 100. The game information display 126 is a display for showing various internal information numerically. The payout tokens indicator 127 is a display for showing the number of tokens that will be paid out to the player as a result of winning a prize. In the following, the expression "given to the player" may be used interchangeably with "paid out to the player". In this embodiment, the stored tokens indicator 125, the game information display 126, and the payout tokens indicator 127 are all composed of 7-segment (SEG) displays.

[0020] The start lever 135 is a lever-type switch used to start the rotation of reels 110 to 112. That is, by inserting the desired number of tokens into the token slot 141 or by operating the bet buttons 130 to 132 and then operating the start lever 135, the reels 110 to 112 will start to rotate. The operation of the start lever 135 is called the game start operation.

[0021] The stop button unit 136 is equipped with stop buttons 137 to 139, consisting of a left stop button 137, a middle stop button 138, and a right stop button 139. The stop buttons 137 to 139 are button-type switches for individually stopping the reels 110 to 112 that have started rotating by operating the start lever 135, and each is associated with a specific reel. More specifically, the left reel 110 can be stopped by operating the left stop button 137, the middle reel 111 can be stopped by operating the middle stop button 138, and the right reel 112 can be stopped by operating the right stop button 139. Hereinafter, operations on the stop buttons 137 to 139 will be referred to as stop operations, with the first stop operation being the first stop operation, the next stop operation being the second stop operation, and the last stop operation being the third stop operation. The reels that are stopped in response to these stop operations will be referred to as the first stop reel, the second stop reel, and the third stop reel, respectively. Furthermore, the sequence in which the stop buttons 137 to 139 are pressed to stop all of the rotating reels 110 to 112 is called the operation sequence or pressing order. Moreover, the operation sequence in which the first stop operation is the left reel 110 is called the "forward pressing operation sequence" or simply "forward pressing," and the operation sequence in which the first stop operation is the right reel 112 is called the "reverse pressing operation sequence" or simply "reverse pressing." In addition, a light-emitting element may be provided inside each of the stop buttons 137 to 139, and if the stop buttons 137 to 139 can be operated, the light-emitting element can be illuminated to inform the player.

[0022] The medal return button 133 is a button to be pressed to remove medals if they become jammed. The settlement button 134 is a button to settle the medals electronically stored in the slot machine 100 and the medals that have been bet, and to dispense them from the medal payout opening 155. The door keyhole 140 is a hole for inserting a key to unlock the front door 102 of the slot machine 100.

[0023] A title panel 162 is provided at the bottom of the stop button unit 136 for displaying the model name and for attaching various certification labels. Below the title panel 162 are a medal payout opening 155 and a medal tray 161.

[0024] The sound hole 145 is a hole for outputting sound from speaker 277 (see Figure 3), which is located at the bottom inside the slot machine 100, to the outside. The side lamps 144, located on the left and right sides of the front door 102, are decorative lamps to enhance the gaming experience. A performance device 160 is installed at the top of the front door 102, and a sound hole 143 is provided at the top of the performance device 160 for outputting sound from speaker 272 (see Figure 3), which is located at the top inside the slot machine 100, to the outside. This display device 160 includes a shutter (shielding device) 163 consisting of two horizontally opening and closing shutters, a right shutter 163a and a left shutter 163b, and a display image display device 157 (liquid crystal display device) positioned behind the shutter 163. When the right shutter 163a and the left shutter 163b are opened horizontally outward in front of the display image display device 157, the display screen of the display image display device 157 appears on the front (player side, front side) of the slot machine 100. Note that any display device capable of displaying various display images and various game information is acceptable, rather than a liquid crystal display device. For example, a multi-segment display (7-segment display), a dot matrix display, an organic EL display, a plasma display, a reel (drum), or a display device consisting of a projector and a screen may be used. The display screen is rectangular and configured so that the entire screen is visible to the player. In this embodiment, the display screen is rectangular, but it may also be square. Furthermore, decorative elements (not shown) can be placed around the periphery of the display screen, so that a portion of the periphery of the display screen is hidden by these decorative elements, resulting in the display screen appearing to have an irregular shape. In this embodiment, the display screen is a flat surface, but it may also be a curved surface.

[0025] Figure 3 is a front view showing the slot machine 100 with the front door open. The main body 101 is a box-shaped structure enclosed by a top panel 261, a left side panel 260, a right side panel 260, a bottom panel 264, and a rear panel 242, with an opening at the front. Inside the main body 101, a main control board storage case 210 containing a main control board 300 is positioned so as not to overlap with a ventilation opening 249 provided at the top of the rear panel 242. Below this main control board storage case 210, a reel unit 700 equipped with three reels 110 to 112 is positioned. To the side of the main control board storage case 210 and the reel unit 700, i.e., on the left side panel 260, a sub-control board storage case 220 containing a sub-control board 400 is provided. Furthermore, an external centralized terminal board 248, which is connected to the main control board 300 and outputs information from the slot machine 100 to an external device, is mounted on the right-hand side panel 260.

[0026] Furthermore, a medal dispensing device 180 (a device that dispenses medals accumulated in a bucket) is installed on the bottom plate 264, and above this medal dispensing device 180, that is, below the reel unit 700, a power supply unit 252 having a power supply board is installed, and a power switch 244 is installed on the front of the power supply unit 252. The power supply unit 252 converts the AC power supplied to the slot machine 100 from an external source into DC, converts it to a predetermined voltage, and supplies it to each control unit and each device, such as the main control unit 300 and the first sub-control unit 400. In addition, it is equipped with an energy storage circuit (e.g., a capacitor) to supply power to a predetermined component (e.g., the RAM 308 of the main control unit 300) for a predetermined period (e.g., 10 days) even after the external power supply is cut off.

[0027] To the right of the medal dispensing device 180, there is a medal auxiliary storage compartment 240, behind which is an overflow terminal (not shown). The power supply unit 252 is provided with a power cord connection part for connecting the power cord 265, and the power cord 265 connected here extends to the outside through a power cord hole 262 opened in the back panel 242 of the main body 101.

[0028] The front door 102 is hinged to the left side panel 260 of the main body 101 via a hinge device 276. Above the pattern display window 113 are a performance device 160, a performance control board (not shown) that controls the performance device 160, and an upper speaker 272. Below the pattern display window 113 are a medal selector 170 for sorting inserted medals, and a passage 266 through which medals pass when the medal selector 170 drops counterfeit medals into the medal tray 161. Furthermore, a bass speaker 277 is provided at a position corresponding to the sound hole 145.

[0029] <Control Unit Circuit Configuration> Next, the circuit configuration of the control unit of the slot machine 100 will be explained in detail using Figure 4. Note that this figure shows a circuit block diagram of the control unit.

[0030] The control unit of the slot machine 100 is broadly composed of a main control unit 300 that controls the progress of the game, a first sub-control unit 400 that controls the main effects in accordance with command signals (hereinafter simply referred to as "commands") transmitted by the main control unit 300, and a second sub-control unit 500 that controls various devices based on commands transmitted from the first sub-control unit 400. Here, regarding the main control unit 300, since a large data capacity would make it difficult to verify the program and could lead to security problems such as becoming a breeding ground for illegal modifications, the data capacity of the ROM 306 and RAM 308 of the main control unit 300 is limited. The main control unit 300 is an example of a means for determining winning combinations and a means for granting bonuses.

[0031] <Main Control Unit> First, let's describe the main control unit 300 of the slot machine 100. The main control unit 300 is equipped with a basic circuit 302 that controls the entire main control unit 300. This basic circuit 302 is equipped with a CPU 304, a ROM 306 that stores control program data, lottery data used when internally drawing winning combinations, the arrangement of reel symbols and stopping positions, a RAM 308 for temporarily storing data, an I / O 310 for controlling the input and output of various devices, a counter timer 312 for measuring time, number of spins, etc., and a WDT (watchdog timer) 314. Note that other storage devices may be used instead of the ROM 306 and RAM 308, and this also applies to the first sub-control unit 400 and the second sub-control unit 500 which will be described later. The CPU 304 of this basic circuit 302 operates by receiving a clock signal of a predetermined period output by a crystal oscillator 315b as the system clock. Furthermore, when power is turned on, the CPU 304 transmits the frequency division data stored in a predetermined area of ​​the ROM 306 to the counter timer 312. The counter timer 312 determines the interrupt time based on the received frequency division data and sends an interrupt request to the CPU 304 at each interrupt time. The CPU 304 then performs monitoring of various sensors and transmits drive pulses based on this interrupt request. For example, if the clock signal output by the crystal oscillator 315b is set to 8MHz, the frequency division value of the counter timer 312 is set to 1 / 256, and the frequency division data in the ROM 306 is set to 47, the reference interrupt time will be 256 × 47 ÷ 8MHz = 1.504ms.

[0032] The main control unit 300 includes a random number generation circuit 316, which is used as a hardware random number counter that varies a value in the range of 0 to 65535 based on a clock signal input from the crystal oscillator 315a, and a startup signal output circuit 338 that outputs a startup signal (reset signal) when the power is turned on. The CPU 304 starts game control when it receives a startup signal from this startup signal output circuit 338.

[0033] Furthermore, the main control unit 300 is equipped with a sensor circuit 320, and the CPU 304 monitors the status of various sensors 318 (bet button 130 sensor, bet button 131 sensor, bet button 132 sensor, medal reception sensor for medals inserted from the medal slot 141, start lever 135 sensor, left stop button 137 sensor, middle stop button 138 sensor, right stop button 139 sensor, settlement button 134 sensor, medal dispensing sensor for medals dispensed from the medal dispensing device 180, optical sensor for the left reel 110, optical sensor for the middle reel 111, optical sensor for the right reel 112, etc.) at interrupt intervals.

[0034] Furthermore, if the sensor circuit 320 detects a high level from the start lever sensor, it outputs a signal indicating this detection to the random number generation circuit 316. Upon receiving this signal, the random number generation circuit 316 latches the value at that moment and stores it in a register that stores the random value used for the lottery.

[0035] Two medal reception sensors are installed in the internal passage of the medal slot 141 to detect whether or not a medal has passed through. Two start lever sensors are installed inside the start lever 135 to detect the player's start operation. The left stop button sensor 137, the middle stop button sensor 138, and the right stop button sensor 139 are installed on the corresponding stop buttons 137 to 139, respectively, to detect the player's operation of the stop buttons.

[0036] The bet button 130 sensor, bet button 131 sensor, and bet button 132 sensor are installed on the corresponding bet buttons 130 to 132, respectively, and detect the insertion operation when inserting tokens electronically stored in RAM 308 as tokens to be used in the game. The payout button 134 sensor is installed on payout button 134. When payout button 134 is pressed once, the electronically stored tokens are paid out (the value stored in RAM 308 is cleared and the same number of tokens are dispensed). The token dispensing sensor is a sensor for detecting the tokens to be dispensed by the token dispensing device 180. Note that each of the above sensors may be a non-contact type sensor or a contact type sensor.

[0037] The optical sensors on the left reel 110, the middle reel 111, and the right reel 112 are installed at predetermined positions on the mounting bases of each reel 110 to 112, and each time a light-shielding piece provided on the reel frame passes over them, they reach an L level. The rotational position information, which indicates how much the reel has rotated from the reference position between the time it reaches an L level and the next time it reaches an L level, is calculated based on the value obtained by counting the clock signal output by the crystal oscillator 315b. When the CPU 304 detects the L level signal, it determines that the reel has rotated once and resets the rotational position information of the reel to zero. This rotational position information is stored in the RAM 308 of the main control unit 300.

[0038] The main control unit 300 includes a drive circuit 322 that drives the stepping motors provided on the reel devices 110 to 112, a drive circuit 324 that drives the solenoid provided on the medal selector 170 that sorts the inserted medals, a drive circuit 326 that drives the motor provided on the medal dispensing device 180, and a drive circuit 328 that drives various lamps 336 (winning line indicator lamp 120, notification lamp 123, game medal insertion ready lamp 124, replay lamp 122, game medal insertion lamp 129, game start lamp 121, stored number indicator 125, game information indicator 126, and payout number indicator 127).

[0039] Furthermore, an information output circuit 334 is connected to the basic circuit 302, and the main control unit 300 outputs game information of the slot machine 100 (for example, information indicating the state of the game) to an information input circuit 652 provided by an external hall computer (not shown) via this information output circuit 334.

[0040] Furthermore, the main control unit 300 includes a voltage monitoring circuit 330 that monitors the voltage value of the power supply supplied to the main control unit 300 from the power management unit (not shown). The voltage monitoring circuit 330 outputs a low voltage signal to the basic circuit 302 indicating that the voltage has dropped when the voltage value of the power supply falls below a predetermined value (9V in this embodiment).

[0041] Furthermore, the main control unit 300 is equipped with an output interface for sending commands to the first sub-control unit 400, enabling communication with the first sub-control unit 400. Information communication between the main control unit 300 and the first sub-control unit 400 is unidirectional; the main control unit 300 is configured to send signals such as commands to the first sub-control unit 400, but the first sub-control unit 400 is configured not to send signals such as commands to the main control unit 300.

[0042] <Deputy Commander> Next, the first sub-control unit 400 of the slot machine 100 will be described. The first sub-control unit 400 receives control commands transmitted by the main control unit 300 via an input interface. The first sub-control unit 400 is equipped with a basic circuit 402 that controls the entire first sub-control unit 400 based on these control commands. This basic circuit 402 is equipped with a CPU 404, a RAM 408 for temporarily storing data, an I / O 410 for controlling the input and output of various devices, and a counter timer 412 for measuring time, number of spins, etc. The CPU 404 of the basic circuit 402 operates by receiving a clock signal of a predetermined period output by a crystal oscillator 414 as the system clock. The ROM 406 stores control programs and data for controlling the entire first sub-control unit 400, data for controlling the backlight lighting patterns and various indicators, etc.

[0043] The CPU 404 transmits frequency division data stored in a predetermined area of ​​the ROM 406 to the counter timer 412 via the data bus at a predetermined timing. The counter timer 412 determines the interrupt time based on the received frequency division data and sends an interrupt request to the CPU 404 at each interrupt time. The CPU 404 controls each IC and circuit based on the timing of this interrupt request.

[0044] Furthermore, the first sub-control unit 400 is equipped with a sound source IC 418, and speakers 272 and 277 are connected to the sound source IC 418 via an output interface. The sound source IC 418 controls the sound output from the amplifier and speakers 272 and 277 in response to instructions from the CPU 404. An S-ROM (sound ROM) containing audio data is connected to the sound source IC 418, and the audio data acquired from this ROM is amplified by the amplifier and output from speakers 272 and 277.

[0045] Furthermore, the first sub-control unit 400 is equipped with a drive circuit 422, and various lamps 420 (upper lamp, lower lamp, side lamp 144, title panel lamp, bet button lamp, reel backlight, etc.) are connected to the drive circuit 422 via an input / output interface.

[0046] Furthermore, the first sub-control unit 400 is equipped with a drive circuit 424 that drives the motor of the shutter 163, and the shutter 163 is connected to the drive circuit 424 via an output interface. This drive circuit 424 outputs a drive signal to a stepping motor (not shown) provided on the shutter 163 in response to a command from the CPU 404.

[0047] Furthermore, the first sub-control unit 400 is equipped with a sensor circuit 426, to which a shutter sensor 428 is connected via an input interface. The CPU 404 monitors the status of the shutter sensor 428 at interrupt intervals.

[0048] Furthermore, the CPU 404 transmits and receives signals to the second sub-control unit 500 via an output interface. The second sub-control unit 500 performs various controls of the performance device 160, including the display control of the performance image display device 157. The second sub-control unit 500 may be composed of multiple control units, such as a control unit that controls the display of the performance image display device 157 and a control unit that controls various performance drive devices (for example, a control unit that controls the motor drive of the shutter 163).

[0049] The second sub-control unit 500 receives control commands transmitted by the first sub-control unit 400 via an input interface and includes a basic circuit 502 that controls the entire second sub-control unit 500 based on these control commands. This basic circuit 502 is equipped with a CPU 504, a RAM 508 for temporarily storing data, an I / O 510 for controlling the input and output of various devices, and a counter timer 512 for measuring time, counts, etc. The CPU 504 of the basic circuit 502 operates by receiving a clock signal of a predetermined period output by a crystal oscillator 514 as the system clock. The ROM 506 stores control programs and data for controlling the entire second sub-control unit 500, as well as data for image display, etc.

[0050] The CPU 504 transmits frequency division data stored in a predetermined area of ​​the ROM 506 to the counter timer 512 via the data bus at a predetermined timing. The counter timer 512 determines the interrupt time based on the received frequency division data and sends an interrupt request to the CPU 404 at each interrupt time. The CPU 504 controls each IC and circuit based on the timing of this interrupt request.

[0051] Furthermore, the second sub-control unit 500 is equipped with a VDP 516 (video display processor), to which a ROM 506 and a VRAM 518 are connected via a bus. Based on signals from the CPU 504, the VDP 516 reads image data stored in the ROM 506, generates a display image using the work area of ​​the VRAM 518, and displays the image on the image display device 157.

[0052] <Reel Rotation Device> Next, the reel rotation device 10 that rotates the reels 110 to 112 of the slot machine 100 will be described in detail using Figures 5 to 7. Figure 5 is an external perspective view showing the reel rotation device 10 of the slot machine 100, which is generally composed of reel drive units 20 to 40 and a case member 12 that houses them. The reel drive units 20 to 40 are structurally made up of the same parts, differing only in the arrangement of the patterns printed on the reel strip 610 (see Figure 6). Each of the reel drive units 20 to 40 (hereinafter, since they have the same configuration, the reel drive unit 20 will be described) is individually and detachably housed in the case member 12.

[0053] Figure 6 is an exploded perspective view of the reel drive unit 20. Figure 7(a) is a schematic side view showing the reel drive unit 20 in its assembled state, and Figure 7(b) is a schematic front view thereof. Note that in Figures 7(a) and (b), some components are omitted from the illustration for explanatory purposes. The reel drive unit 20 has a configuration for moving and displaying patterns, which includes a reel 110, a drive device 604 that rotates the reel 110, a rotation detection device 606 that detects the rotational position of the reel 110, and a reel illumination device 608 that illuminates the patterns on each reel 110 from inside the reel 110.

[0054] The reel 110 consists of a thin-walled cylindrical reel strip 610, a first reel frame 612 attached to the left side of the reel strip 610 and supporting the left side of the reel strip 610, and a second reel frame 614 attached to the right side of the reel strip 610 and supporting the right side of the reel strip 610.

[0055] The first reel frame 612 is composed of an annular frame portion 612A, six support portions 612B that extend from the frame portion 612A toward the center of the frame portion 612A, and a cylindrical mounting portion 612C that protrudes toward the drive unit 604 from the tips of the six support portions 612B toward the drive unit 604.

[0056] One of the six support portions 612B has a plate-shaped light-shielding piece 612D protruding toward the rotation detection device 606, and is configured to pass between the light-emitting and light-receiving portions of the index sensor 606A, which will be described later. In addition, the cylindrical mounting portion 612C has four engagement recesses formed at approximately equal intervals (approximately 90-degree intervals in this example) in the circumferential direction. These four engagement recesses are fitted to four engagement protrusions of the movable gear 620, thereby engaging and fixing the first reel frame 612 to the movable gear 620.

[0057] The second reel frame 614 consists of an annular member having approximately the same diameter as the frame portion 612A of the first reel frame 612, and is positioned on the opposite side of the first reel frame 612, with the reel strip 610 in between.

[0058] The drive unit 604 consists of a drive motor 616, a drive gear 618 attached to the motor shaft 616A of the drive motor 616, a movable gear 620 that meshes with the drive gear 618, and a base 622 that rotatably supports the movable gear 620 via a support member 623 and a washer 621. The drive motor 616 and the base 622 are fixedly supported to a plate-shaped metal frame 626 by a plurality of mounting screws 624.

[0059] In this embodiment, the drive motor 616 is composed of a 1-2 phase excitation type stepping motor 700 (details will be described later). The movable gear 620 is composed of a gear with a larger diameter than the drive gear 618, and the movable gear 620 and the drive gear 618 constitute a gear set. Furthermore, as described above, after the movable gear 620 is engaged with the mounting portion 612C of the first reel frame 612, it is fixed to the first reel frame 612 using mounting screws 624 and washers 621, and is rotatably supported on the base 622, so that it can rotate together with the first reel frame 612.

[0060] The rotation detection device 606 consists of an optical index sensor 606A comprising a light-emitting unit and a light-receiving unit, and a mounting base 606B to which the index sensor 606A is attached. The light-shielding piece 612D provided on the first reel frame 612 passes between the light-emitting and light-receiving units of the index sensor 606A (see Figure 7(b)). The mounting base 606B is fixed to the metal frame 626 by mounting screws 624. Based on the detection results of the rotation detection device 606, the slot machine 100 determines the rotational position of the symbols on the reels 110-112 and stops the reels 110-112 so that the desired symbols are displayed on the winning line 114. In other words, when the light-shielding piece 612D of the rotating reel 110 is detected by the index sensor 606A, the main control unit 300 resets the rotational position information of the reels and becomes able to control the stopping position of the reels.

[0061] The reel lighting device 608 consists of a lighting board 608B with a single cold cathode tube positioned in the center, a lighting case 608C which includes a light guide plate for guiding the light emitted from the cold cathode tube in a predetermined direction when the lighting board 608B is mounted, and a back cover 608A which covers the back surface of the lighting board 608B. The lighting case 608C is fixed to the metal frame 626 by mounting screws 624 when the lighting board 608B and the back cover 608A are mounted on it.

[0062] <Stepping motor> Figure 8 is an exploded perspective view of the stepping motor 700. As shown in Figure 8, the stepping motor 700 consists of a motor shaft 710, a case member 720 that supports the motor shaft 710, a first bearing 722 and a second bearing 724 disposed in the case member 720 and supporting the motor shaft 710, a stator 730 consisting of a fixed electromagnet disposed inside the case member 720, and a rotor 740 that is rotatably mounted on the motor shaft 710. The stepping motor 700 in this embodiment is a PM (Permanent Magnet) type stepping motor, and is configured to rotate once in 96 steps of 1-2 phase excitation. In this embodiment, the gear ratio between the reel and the motor is 1:5.25, so the reel rotates once in 504 steps (= 5.25 × 96).

[0063] The motor shaft 710 is the shaft to which the drive gear 618 shown in Figures 6 and 7 is attached and which outputs power. Hereafter, the end of the motor shaft 710 to which the drive gear 618 is attached will be called the output end 710A, and the opposite end will be called the rear end 710B.

[0064] The case member 720 is a hollow cylindrical body with a bottom, consisting of a substantially cylindrical base portion 720A with an open end and a lid portion 720B disposed to close the opening of the base portion 720A. The case member 720 houses the stator 730 and rotor 740 inside and supports the motor shaft 710, which penetrates from the bottom of the base portion 720A to the lid portion 720B, via a first bearing 722 and a second bearing 724. The base portion 720A is also provided with a fixing member 720C, which has holes through which mounting screws 624 for fixing support to the metal frame 626 shown in Figure 6 are inserted.

[0065] The first bearing 722 is a substantially cylindrical sliding bearing positioned approximately in the center of the lid portion 720B of the case member 720, and rotatably supports the motor shaft 710 near the output end 710A.

[0066] The second bearing 724 is a substantially cylindrical sliding bearing positioned approximately in the center of the bottom of the base portion 720A of the case member 720, and rotatably supports the motor shaft 710 near its rear end 710B.

[0067] The stator 730 is arranged to surround the rotor 740, and drive coils are wound in two stages, upper and lower (A phase and B phase). In this embodiment, as shown in Figure 8, the magnetic pole teeth form a triangle (the upward-facing ones are called A phase and B phase, and the downward-facing ones are called A- phase and B- phase. The A phase and B phase have a phase relationship of 90 degrees electrical angle, and the A phase and A- phase and the B phase and B- phase have a phase relationship of 180 degrees electrical angle), and each magnetic pole (A phase, A- phase, B phase, B- phase) has 12 teeth around its circumference. Figure 9 shows the arrangement of the magnetic poles of the stator 730. As shown in Figure 9, the magnetic poles are arranged circumferentially in the order of A phase, B phase, A- phase, and B- phase in a clockwise direction.

[0068] In this embodiment, the rotor 740 is composed of permanent magnets and has 24 magnetic poles.

[0069] The operating principle of the stepping motor 700 will now be explained. The stepping motor 700 is configured to rotate the rotor 740 by passing current through coils wound around the stator 730 to sequentially magnetize each phase of the stator 730 based on the excitation pattern described later, thereby attracting the rotor 740 with magnetic force.

[0070] In the 1-2 phase excitation type, the rotor 740 is made to rotate in a constant direction by exciting the four phases of the stator 730 described above in the following order: for example, A phase (1 phase excitation) → A phase and B phase (hereinafter referred to as AB phase, 2 phase excitation) → B phase (1 phase excitation) → A- phase and B phase (hereinafter referred to as AB phase, 2 phase excitation) → A- phase (1 phase excitation) → A- phase and B- phase (hereinafter referred to as AB- phase, 2 phase excitation) → B- phase (1 phase excitation) → A phase and B- phase (hereinafter referred to as AB- phase, 2 phase excitation) → A phase (1 phase excitation) → ...

[0071] More specifically, the CPU 304 of the main control unit 300, via the drive circuit 322 shown in Figure 4, outputs an on-level pulse signal (e.g., a high-level signal) to the phase of the stator 730 of the stepping motor 700 that is to be excited, and at the same time outputs an off-level pulse signal (e.g., a low-level signal) to the phase that is not to be excited, thereby exciting a predetermined phase. As a result, the rotor 740 of the stepping motor 700 is rotated by a predetermined angle (1 step). For example, the CPU 304 of the main control unit 300 outputs an on-level pulse signal to the A phase of the stator 730 of the stepping motor 700, and at the same time outputs off-level pulse signals to the B phase, A- phase, and B- phase, thereby exciting only the A phase and rotating the rotor by 1 pulse (1 step), and thereafter, by switching the excitation in the above order, the rotor is rotated by a predetermined number of pulses. The rotation of A phase → AB phase → B phase → AB phase → A- phase → AB- phase → B- phase → AB- phase (or A phase → AB- phase → B- phase → AB- phase → A phase → AB phase → B phase → AB phase) consisting of 8 pulses (8 steps) will be referred to as one cycle below.

[0072] In this embodiment, as described above, the number of pulses required to rotate the reel once (360 degrees) is set to 504 pulses (504 pulses / 8 pulses = 63 cycles). Therefore, the rotation angle of the rotor 740 per pulse is approximately 0.71428 degrees (= 360 / 504).

[0073] Furthermore, the number of steps (pulses) required to rotate the reel once (360 degrees) is 504 steps. For example, if there are 21 symbols on one reel, the number of steps per symbol is 504 / 21 = 24 steps.

[0074] <Excitation Table> The drive signals output from the CPU 304 to the drive circuit 322 are stored as an excitation table in the ROM 306. The CPU 304 outputs the instructed drive signals by referring to this excitation table. Figure 10 is a table showing the contents of the excitation table in this embodiment. The data in each excitation table (also called rotation control data, as it is data for controlling the rotation of the reel) is configured to represent the phase to be excited and the excitation force by combining six bit data (specifically, A-I0, A-I1, A-Phase, B-I0, B-I1, B-Phase). Specifically, the combination of A-I0 and A-I1 indicates the magnitude of the current (excitation force) required to excite the A-phase or A-phase coil. When A-I0 is 0 and A-I1 is 0, it indicates 0%; when A-I0 is 1 and A-I1 is 0, it indicates 20%; when A-I0 is 0 and A-I1 is 1, it indicates 60%; and when A-I0 is 1 and A-I1 is 1, it indicates 100%. When A-Phase is 1, it indicates A-phase excitation, and when it is 0, it indicates A-phase excitation. Similarly, the combination of B-I0 and B-I1 indicates the magnitude of the current (excitation force) for exciting the B-phase or B-phase coil. When B-I0 is 0 and B-I1 is 0, it indicates 0%; when B-I0 is 1 and B-I1 is 0, it indicates 20%; when B-I0 is 0 and B-I1 is 1, it indicates 60%; and when B-I0 is 1 and B-I1 is 1, it indicates 100%. A B-Phase of 1 indicates excitation of the B-phase, and a B-Phase of 0 indicates excitation of the B-phase.

[0075] For example, excitation table "55H" with table number "B0" has A-I0 at 1, A-I1 at 0, A-Phase at 1, B-I0 at 1, B-I1 at 0, and B-Phase at 1, indicating that the A and B phases are excited to 20%. Similarly, excitation table "26H" with table number "C2" has A-I0 at 0, A-I1 at 1, A-Phase at 1, B-I0 at 0, B-I1 at 0, and B-Phase at 0, indicating that the A phase is excited to 60% (the B phase is 0%, so it is not excited). Therefore, when switching the table numbers in the order "C0" → "C1" → "C2" → "C3" → "C4" → "C5" → "C6" → "C7", each phase is excited to 60% in the order of AB phase → A phase → AB- phase → B- phase → AB- phase → A- phase → AB phase → B phase, and the rotor 740 can be rotated by the angle of one cycle. In this embodiment, the reel is controlled to rotate by outputting the data (rotation control data) of the excitation table, which is composed of 6 bits, as a drive signal to the drive circuit 322. In this embodiment, as shown in Figure 10, an excitation force of 0% is also referred to as no excitation, an excitation force of 20% as weak excitation, an excitation force of 60% as medium excitation, and an excitation force of 100% as strong excitation.

[0076] <Rotation control table> Figure 11 is a table showing the contents of the rotation control table in this embodiment. The rotation control table is stored on the ROM 306 and stores the contents of the rotation control for each reel control status (specifically, it consists of a general-purpose offset counter value, an excitation table, and holding parameters). The reel control status is information about the control state of each reel 110 to 112, which is stored independently for each reel. One of the following information is stored for each reel 110 to 112: "Stopped Control State (Stopping Control in Progress)" which indicates that each reel 110 to 112 is stopped; "Accelerated State (Accelerating Control in Progress)" which indicates that each reel 110 to 112 is accelerating; "Constant Speed ​​State (Constant Speed ​​Control in Progress)" which indicates that each reel 110 to 112 is at a constant speed; "Retracted State (Retraction Control in Progress)" which indicates that each reel 110 to 112 is retracted; "Brake State (Brake Control in Progress)" which indicates that each reel 110 to 112 is braked; or "Reel Performance Control in Progress" which indicates that each reel 110 to 112 is performing a reel performance. In this embodiment, the constant speed state is further classified into two states with different excitation forces: "Constant Speed ​​1 State (Constant Speed ​​1 Control in Progress)" which is set immediately after the acceleration state, and "Constant Speed ​​2 State (Constant Speed ​​2 Control in Progress)" which is set immediately after the Constant Speed ​​1 State (Constant Speed ​​1 Control in Progress). The Constant Speed ​​1 State is provided to ensure stable rotation of reels 110-112 and to save power, while the Constant Speed ​​2 State is provided to further reduce the excitation force and suppress heat generation of reels 110-112. The slot machine 100 of this embodiment controls the rotation of reels 110-112 by changing the reel control status from stop control → acceleration control → constant speed 1 control → constant speed 2 control → retraction control → brake control → stop control, and selecting an excitation table (rotation control data) corresponding to each reel status.

[0077] For example, when the reel control status is "Acceleration Control in Progress," as shown in Figure 11, the rotation control data for excitation table "77H" corresponding to the general offset counter value "0" is first held for "12" minutes, then the rotation control data for excitation table "07H" corresponding to the general offset counter value "1" is held for "12" minutes, then the rotation control data for excitation table "37H" corresponding to the general offset counter value "2" is held for "3" minutes, then the rotation control data for excitation table "30H" corresponding to the general offset counter value "3" is held for "3" minutes, and so on, with the rotation control data being set sequentially from the top row to the bottom of the table. Then, by gradually decreasing the hold time of the sequentially set rotation control data, reels 110 to 112 are accelerated.

[0078] The general-purpose offset counter value is a number (0-based) that indicates the order in which each rotation control data is executed in each reel control status, and it is a cyclical value that returns to 0 after 7. The hold time (hold parameter) indicates the time for which the set rotation control data is held, and 1 hold time represents 1 interrupt time (for example, 1.49 ms). Therefore, as shown in Figure 11, in this embodiment, "acceleration control" is configured to perform 100% excitation (strong excitation) of phases 1-2, requiring a time of 89.4 ms (= 1.49 × 60).

[0079] Furthermore, when the reel control status is "Constant Speed ​​1 Control," as shown in Figure 11, the rotation control data for excitation table "77H" corresponding to the general-purpose offset counter value "0" is first held at "1" for a certain period of time, then the rotation control data for excitation table "07H" corresponding to the general-purpose offset counter value "1" is held at "1" for a certain period of time, then the rotation control data for excitation table "37H" corresponding to the general-purpose offset counter value "2" is held at "1" for a certain period of time, and so on. The rotation control data listed in the table is set as one set and repeated 16 times. In other words, the rotation control data that is set sequentially is switched at a holding time of 1 and executed 16 times, thereby stably rotating the reel at a constant speed. As a result, "Constant Speed ​​1 Control" in this embodiment is configured to require 190.72 ms (= 1.49 × 8 × 16 sets) with 1-2 phase 100% excitation (strong excitation). During the constant speed control described above, the control pattern, such as one set of rotation control data, is repeated a predetermined number of times.

[0080] Furthermore, when the reel control status is "Constant Speed ​​2 Control," as shown in Figure 11, the rotation control data for excitation table "66H" corresponding to the general-purpose offset counter value "0" is first held at "1" for a certain period of time, then the rotation control data for excitation table "06H" corresponding to the general-purpose offset counter value "1" is held at "1" for a certain period of time, then the rotation control data for excitation table "26H" corresponding to the general-purpose offset counter value "2" is held at "1" for a certain period of time, and so on, with the rotation control data being set sequentially from the top row to the bottom row of the table. In other words, the reel is rotated at a constant speed by switching the sequentially set rotation control data with a holding time of 1. As a result, in this embodiment, "Constant Speed ​​2 Control" is configured to maintain a state of 1-2 phase 60% excitation (medium excitation) until a stop operation is performed in the stoppable state, which will be described in more detail later. The constant speed 2 control described above repeats a control pattern, such as rotation control data with a general-purpose offset counter value of "0" to "7", an indefinite number of times. When a stop operation is performed in a state where stopping is possible, the constant speed 2 control terminates even if it is in the middle of the control pattern.

[0081] Furthermore, when the reel control status is "Retraction Control in Progress," the rotation control data used in "Constant Speed ​​2 Control in Progress" continues to be set sequentially. For example, when transitioning to "Retraction Control in Progress" after setting the rotation control data for excitation table "42H" corresponding to a general-purpose offset counter value of "5" in "Constant Speed ​​2 Control in Progress" for a holding time of "1," the rotation control data for excitation table "62H" corresponding to a general-purpose offset counter value of "6" is set for a holding time of "1," and then the rotation control data for excitation table "64H" corresponding to a general-purpose offset counter value of "7" is set for a holding time of "1." After that, the rotation control data for each excitation table corresponding to a general-purpose offset counter value of 0 to 7 is sequentially and repeatedly set for a number of steps equivalent to the number of retraction frames (number of retraction frames × 24) for a holding time of "1" (in this embodiment, to stop in phase AB).

[0082] Furthermore, when the reel control status is "Brake control in progress," as shown in Figure 11, 2-phase 100% excitation (strong excitation) is performed for 74.5 ms, which applies a brake to the rotating reel and stops it.

[0083] Furthermore, when the reel control status is "reel stop control in progress," the stop state is maintained by continuing 2-phase 20% excitation (weak excitation), as shown in Figure 11.

[0084] Below, using Figure 12, we will explain an example of reel rotation control that differs from that shown in Figure 11.

[0085] As shown in the example in Figure 11, the rotation of the reels can be controlled using different excitation forces such as no excitation, weak excitation, medium excitation, and strong excitation. In the example in Figure 11, 1-2 phase excitation and 2-phase excitation are used, but as shown in Figure 12, for example, a configuration in which the excitation type and excitation time (number of interrupts) are changed may also be used, such as 1-2 phase excitation and 4-phase excitation. Figure 12 shows the changes in excitation type and excitation time when this configuration is adopted.

[0086] For example, when the reel control status is "Acceleration Control in Progress," as shown in Figure 12, the rotation control data is set sequentially from the top row to the bottom of the table, starting with holding the 2-phase excitation for 190ms (130 interrupts), then holding the 1-phase excitation for 11.92ms (8 interrupts), then holding the 2-phase excitation for 10.47ms (7 interrupts), and so on. By gradually decreasing the holding time of the sequentially set rotation control data, reels 110 to 112 are accelerated.

[0087] Furthermore, when the reel control status is "constant speed control in progress," as shown in Figure 12, the rotation control data is set sequentially from the top row to the bottom row of the table, starting with holding single-phase excitation for 1.49 ms (1 interrupt), then holding two-phase excitation for 1.49 ms (1 interrupt), then holding single-phase excitation for 1.49 ms (1 interrupt), and so on. In this control data, the reel is rotated stably at a constant speed by switching between single-phase excitation and two-phase excitation every 1.49 ms (1 interrupt).

[0088] Furthermore, when the reel control status is "Brake control in progress," as shown in Figure 12, four-phase excitation is performed for 208.6 ms to apply a brake to the rotating reel, causing it to stop. After that, the reel control status changes to "Reel stop control in progress."

[0089] When the reel control status is "reel stop control in progress," the system enters a zero-phase excitation state (excitation open, no excitation) as shown in Figure 12. Note that, in addition to zero-phase excitation, the system may also be configured to hold the reel in a one-phase or two-phase excitation state for stabilization.

[0090] <Regarding the circuit configuration related to the reel> Here, an example of the circuit configuration for driving reels 110 to 112, as shown in Figure 4, will be explained using Figure 13.

[0091] Figure 13 shows the main control board 300B in the center, with the power supply board 252B connected to the main control board 300B by harness H1 and the medal dispensing device 180 connected by harness H2 shown on the left side of the drawing. Further on the right side of the drawing are the left reel motor board 700BL, the middle reel motor board 700BC, and the right reel motor board 700BR, all connected to the main control board 300B by harnesses H3 to H5.

[0092] The power supply board 252B is a board installed in the power supply unit 252, and in Figure 13, it supplies power voltages of 5V and 24V and ground to the main control board 300B, etc. Furthermore, it supplies power voltage and ground to the medal dispensing device 180, the left reel board 700BL, the middle reel board 700BC, and the right reel board 700BR via the main control unit 300B.

[0093] The main control board 300B is the board corresponding to the main control unit 300 in Figure 4. Note that some components and wiring are omitted in the diagram. The main control board 300 shows the CPU 304 in Figure 4, and various control signals are output from this CPU 304. Figure 13 shows that wiring is provided from the CPU 304 to the sub-control board 400B, which corresponds to the first sub-control unit 400 and the second sub-control unit 500. It also shows that wiring is provided from the CPU 304 to IC1, IC2, and IC3, which output drive signals for reels 110 to 112. These IC1 to 3 correspond to the drive circuit 322 in Figure 4 and control each stepping motor 700 of reels 110 to 112 according to the drive signals from the CPU 304. Figure 13 shows that the wiring from IC1 to 3 is connected to the terminals of each stepping motor 700 of reels 110 to 112. Note that in Figure 13, terminal L_REEL_Φ0 is for A-phase excitation control, terminal L_REEL_Φ1 is for B-phase excitation control, terminal L_REEL_Φ2 is for A-phase excitation control, and terminal L_REEL_Φ3 is for B-phase excitation control.

[0094] Furthermore, it is shown that a path is provided for inputting rotation position signals from each index sensor 606A for detecting the rotation position of reels 110 to 112 to the CPU 304 via IC0. In addition, it is shown that wiring is provided for outputting a hopper drive signal from the CPU 304 to the medal dispensing device 180 via IC4, and for inputting a dispensing sensor signal from the medal dispensing device 180 to the CPU 304 via IC4.

[0095] Figure 14 is a simplified diagram of the circuit that controls the stepping motor 700 of the left reel board 700BL in Figure 13.

[0096] Figure 14 shows, similar to Figure 13, a resistor R1 and an LEDD1 connected in series between the 24V power supply and ground of the main control board 300B. Of these, LEDD1 is responsible for indicating that the power is on by emitting light.

[0097] Figure 14 also shows capacitor CA connected between the 24V power supply and ground of the main control board 300B. Figure 13 shows that multiple capacitors (e.g., capacitors C1 to C3) are provided to stabilize operation and remove noise, but capacitor CA shown in Figure 14 comprehensively represents these multiple capacitors.

[0098] Figure 14 also shows the load component ZA connected between the 24V power supply and ground of the main control board 300B. While Figure 13 shows that various wirings and components are provided, the load component ZA shown in Figure 14 comprehensively represents these wirings and components.

[0099] Figure 14 also shows that the coils controlling each phase of the stepping motor 700 on the left reel board 700BL, and IC1 which controls these coils, are connected between the 24V power supply and ground of the main control board 300B. Note that there are coils controlling each phase, such as coil LA which controls phase A, coil LB which controls phase B, coil LA- which controls phase A-, and coil LB- which controls phase B-, but in Figure 14 these coils are shown together as a single coil.

[0100] <Regarding the operation when the reel is manually rotated with the power off (1)> In this embodiment, abnormalities can sometimes be detected by manually rotating the reel. This operation will be explained below with reference to Figures 14 and 15. In the following explanation, the left reel 110 will be described, but the same applies to the other reels.

[0101] First, let's explain the control of the left reel 110. As mentioned above, the CPU 304 rotates the left reel 110 by sequentially switching the corresponding excitation table (see Figure 10) according to the rotation status of the left reel 110 shown in Figure 11. Specifically, IC1, which receives a drive signal from the CPU 304, controls the magnitude of the current flowing through the coils LA, LB, LA-, and LB- corresponding to each phase so that the excitation state corresponds to the excitation table (no excitation, weak excitation, medium excitation, strong excitation), causing the left reel 110 to rotate and stop. The excitation state of each phase of the stepping motor 700 is also controlled by IC2 and IC3, respectively, for the middle reel 111 and the right reel 112. In Figure 14, IC1 is located between the ground and the coils LA, LB, LA-, and LB-, but it is also possible to configure IC1 to be located between the 24V power supply and the coils LA, LB, LA-, and LB-, and to control the magnitude of the current flowing through the coils LA, LB, LA-, and LB- corresponding to each phase.

[0102] Next, we will explain the case where the power is off and there is no abnormality in the circuit (i.e., the connectors and harnesses are properly connected). In this case, when the left reel 110 is rotated manually, an electromotive force is generated sequentially in the coils LA, LB, LA-, and LB- of each phase due to electromagnetic induction (the coils act as power supplies of several volts). Note that the reel can rotate in a forward direction (the same direction as during gameplay) and a reverse direction (the opposite direction to the rotation during gameplay). Depending on the direction, the electromotive force may be generated in the order of coil LA→LB→LA-→LB-→LA or in the order of coil LA→LB-→LA-→LB→LA. However, when the reel is rotated, regardless of the direction of rotation, a current flows in the opposite direction to when the reel is driven (counterclockwise from the stepping motor 700 in Figure 14). Specifically, as shown by the dotted arrows (1) to (5) in Figures 14 and 15, a circuit configuration PT1 is established in which current flows from the stepping motor 700 of the left reel 110 (more specifically from coils LA, LB, LA-, and LB-) through resistor R1, LEDD1, capacitor CA, load component ZA, and further through IC1 to the stepping motor 700. Current flows through this circuit configuration PT1.

[0103] Here, IC1, when power is supplied, switches the on / off state of the path connected to coils LA, LB, LA-, and LB- through the switching operation of a transistor (more precisely, an FET). When the path is off, it is the same as being in an isolated state in the circuit, and the same as having the connector unplugged. On the other hand, when the power is turned off, this switching operation does not function, and the circuit may be in a conductive state. To elaborate on IC1, the FET inside IC1 switches between conductive and non-conductive (isolated) states depending on whether the power of the gaming machine is on or off, and whether the reels are rotating or stopped. When the power of the gaming machine is off (no gate voltage is applied), as mentioned above, the FET becomes conductive and the circuit configuration PT1 is established. On the other hand, when the power of the gaming machine is on and the reels are stopped (gate voltage is applied), the FET becomes isolated and the circuit configuration PT1 is not established. This is because, when the FET is in a conductive state, the reel motor becomes energized and fixed, making its movement heavy and allowing it to maintain its stopping position, but this generates heat. If the reel is then rotated, it will generate even more heat, so to prevent exceeding the allowable power loss, the FET is kept in an insulated state and not energized (de-energized) when the reel is stopped to suppress heat generation. However, if it is desired to maintain the reel's stopping position as much as possible, a weak current is applied to fix it. On the other hand, when the power to the gaming machine is on and the reel is rotating and stopping, the motor needs to be energized for acceleration, maintaining a constant rotation speed, and stopping the reel, so the FET is made conductive. Below, an example of the current path inside IC1 when the power is off will be explained using Figure 15.

[0104] Figure 15 shows transistors TR11, TR12, TR13, and TR14 located inside IC1. These transistors TR11, TR12, TR13, and TR14 have so-called parasitic diodes and parasitic capacitances (physical configurations equivalent to diodes and capacitors in structure) that are not located inside IC1. These parasitic diodes PD11, PD12, PD13, and PD14 are shown as dotted lines in Figure 15. The current path inside IC1 when the left reel 110 is manually rotated (in Figure 15, the path enters from the bottom (ground side) of IC1 and exits to the right side (coil LA, LB, LA-, LB- side)) is formed by these parasitic diodes PD11, PD12, PD13, and PD14. Depending on the type of IC, there may also be voltage-resistant protection diodes to protect the transistors from back electromotive force; in this case, the current path is formed by these voltage-resistant protection diodes. Furthermore, in ICs that incorporate FETs as described above, the FETs become conductive, creating a current path.

[0105] Furthermore, in response to the electromotive force generated by electromagnetic induction, a back electromotive force (power that attempts to counteract the changes in the magnetic flux and current of the coils) is generated sequentially in the coils LA, LB, LA-, and LB- of each phase. This back electromotive force creates a load (difficulty in rotating the left reel 110, resistance to manual rotation) when the left reel 110 is rotated manually. More specifically, if the coil of the stepping motor 700 is considered as 0V when the power is off, then when the left reel 110 is rotated manually, an electromotive force (reverse voltage) of several volts is generated by electromagnetic induction. This then generates a back electromotive force that attempts to counteract this change from 0V to several volts, and this becomes the load (resistance, the weight when moving the reel, the torque in the opposite direction) when it is rotated manually. This back electromotive force increases in proportion to the change in current (speed) due to electromagnetic induction, and for example, the load is greater when the left reel 110 is rotated quickly at high speed than when it is rotated slowly from a stationary state. In other words, if the amount of change in current (speed) within a certain period is large, the load when rotating manually will also be large, and if the amount of change in current (speed) within a certain period is small, the load when rotating manually will also be small.

[0106] Furthermore, a portion of the current generated in the coils LA, LB, LA-, and LB- of each phase flows into the capacitor CA, where it is charged (charged and stored). The charge stored in capacitor CA is released (flows to ground) via load components such as ZA, but a portion of it also flows into the coils LA, LB, LA-, and LB-, causing a change in the load when the left reel 110 is rotated manually.

[0107] On the other hand, if the power is turned off and there is an abnormality in the circuit configuration PT1 corresponding to coils LA, LB, LA-, LB- (the circuit is not connected, the resistance value is higher than normal, the connector or harness is not properly connected, or the power line or drive signal line in the harness is broken), then there will be parts of the circuit configuration PT1 that are not functioning due to this abnormality. As a result, even if the left reel 110 is rotated manually, no current will flow (or the current will be low) in the abnormal or non-functioning circuit configuration PT1, and no back electromotive force or load will be generated (or the back electromotive force and load will be small) when the left reel 110 is rotated manually.

[0108] Based on the above, it is possible to infer whether or not there is a malfunction in the circuit around the motor of the left reel 110 by observing the difference in load when the left reel 110 is rotated manually. For example, if harness H3 is disconnected, even if the left reel 110 is rotated manually, no back electromotive force or load will be generated in any of the circuits connected to the coils LA, LB, LA-, and LB- of each phase. In this case, it is easy to recognize whether or not there is a load when the left reel 110 is rotated manually, making it the easiest situation to infer that there is a malfunction in the circuit around the motor of the left reel 110. Furthermore, since the difference in load occurs regardless of whether the reel is rotating in the forward or reverse direction, the operator's ability to check the reel is improved as the direction of reel movement is not limited to one direction. The same applies not only to reels but also to hopper devices that dispense medals. The same applies to movable objects used in performances; if a movable object can move left and right, the difference in load can be perceived whether it is moved to the right or left; if a movable object can move up and down, the difference in load can be perceived whether it is moved upward or downward; if a movable object rotates, the difference in load can be perceived whether it is moved in the forward or reverse direction; or the difference in load can be perceived whether it is moved clockwise or counterclockwise.

[0109] In the above example, we focus on the load when the reel is rotated manually (by the inspector's hand, not by the drive control of the gaming machine), but this action is caused by the rotation of the motor. Therefore, the force that rotates the motor can be any force from outside the motor (external force), for example, if the worker's clothing or tools unintentionally touch the reel during inspection or maintenance work with the gaming machine door open, causing the reel to rotate in the forward or reverse direction, this can also be considered an action caused by an external force, and is not necessarily limited to manual operation. Furthermore, the load can be rephrased as the feel, the weight when moving the reel, or the resistance when moving the reel (force in the opposite direction to the applied external force, force that tries to return to its original position even when an external force is applied, force that tries to stay in place even when an external force is applied), and its magnitude may be expressed as large (small) or heavy (light).

[0110] Furthermore, when rotating the reel with an external force, one can rotate it without releasing their hand, for example. As mentioned above, the amount of rotation is not limited because the presence or absence of load differs depending on whether the circuit configuration PT1 is established. However, since the operator feels resistance for a longer period of time when moving four frames rather than half a frame, a larger amount of rotation (four frames, a quarter turn, half a turn) allows the operator to feel the load (resistance) for a longer period of time, making it easier to distinguish and compare differences in load. Alternatively, one can rotate the reel vigorously and then let it rotate by inertia after releasing their hand. Although no resistance is felt after releasing the reel, if the load is large, the reel will be more difficult to rotate than when the load is small. Therefore, differences in the amount of rotation, rotation speed, and the time until rotation stops can be used to judge differences in load and infer abnormalities. In other words, if the reel is rotated manually with an external force and the resistance is heavy, and then released to allow it to rotate by inertia, the large load makes it difficult to rotate, resulting in a smaller amount of rotation (movement / action) before stopping and a shorter time until stopping. On the other hand, if the reel is rotated manually with an external force and the resistance is light, and then released to allow it to rotate by inertia, the small load makes it easy to rotate, resulting in a larger amount of rotation (movement / action) before stopping and a longer time until stopping. It is preferable that the external force applied to the reel (motor) remains constant, regardless of whether the load is large (for example, when the power is off) or small (for example, when the power is on). This is because the amount of inertial rotation changes depending on the power supply status and harness connection status, so applying a constant external force allows for a more accurate assessment of the power supply status and any abnormalities. Furthermore, "a constant external force" may refer to the amount of inertial rotation after moving the reel halfway around with an external force at its steady rotational speed (79 rotations per minute, or 750ms per revolution). However, the amount of inertial rotation must be driven by a certain amount of external force; for example, if the external force moves a stepping motor by one step, the load can be determined, but it is difficult to determine the amount of inertial rotation.Alternatively, a string with a weight of a certain weight attached to it can be hung downwards from the reel to create a constant external force. However, since the load is generated depending on whether circuit configuration PT1 is established or not, the amount of inertial rotation changes even if the external force applied to the reel (motor) is not constant, so it is possible to understand the energized state and any abnormalities, and thus achieve a similar effect. As a result, even if the operator does not feel much resistance when manually rotating the reel, they can determine whether it is energized or if there is an abnormality by the amount of rotation due to inertia and the time it takes to stop after releasing their hand. In addition, even if the reel is accidentally touched while working with the gaming machine door open, if it is energized, the load will be small and the amount of movement will be large, making it easier to notice that the reel has been moved unintentionally and to return it to the stopping position of the symbols before the work was done. Note that this applies not only to reels but also to movable display devices (movable parts).

[0111] Furthermore, "when harness H3 is disconnected" refers to a situation where connector CN2, which is the board-side connector on the main control board 300B, and connector CN2-1, which is the harness-side connector on one end of harness H3, are not properly connected. Although not shown in the diagram, the same applies when the motor connector (motor-side connector) and harness-side connector CN2-2, which is on the other end of harness H3 that can be connected to the motor-side connector, are not properly connected. In other words, it refers to a situation where the connection points of connector CN2-1 and / or connector CN2-2 on harness H3 are not properly connected. On the other hand, when harness H3 is not disconnected, manually rotating the left reel 110 generates back electromotive force in all the circuits connected to the coils LA, LB, LA-, and LB- of each phase, resulting in a greater load when manually rotating the left reel 110 than when harness H3 is disconnected. This confirms that there is no abnormality in the motor-related circuit of the left reel 110.

[0112] Furthermore, "when harness H3 is not disconnected" refers to the case where connector CN2, which is the board-side connector on the main control board 300B, and connector CN2-1, which is the harness-side connector on one end of harness H3, are properly connected. Also, although not shown in the diagram, the same applies when the motor connector (motor-side connector) and harness-side connector CN2-2, which is on the other end of harness H3 that can be connected to the motor-side connector, are properly connected. In other words, it refers to the case where the connection points of connector CN2-1 and / or connector CN2-2 on harness H3 are properly connected.

[0113] An abnormality in the circuit configuration corresponding to coils LA, LB, LA-, and LB- could be, for example, if harness H3 connecting the main control board 300B and the reel board 700BL is disconnected (connectors CN2 and CN2-1 are not connected, or the motor-side connector and connector CN2-2 are not connected), or if some of the wiring on harness H3 or the wiring on the boards (main control board 300B, reel board 700BL) is broken. Other examples include cases where the terminals on harness H3 are not in the correct connection positions, resulting in no connection, or where the wiring is connected to a degree that allows for some operation, but the resistance value of the wiring is higher than in a normal state because the terminals on harness H3 are not in the correct connection positions. Examples of cases where the wiring is not connected or the resistance value of the wiring is high include cases where one or both of a pair of terminals are missing (for example, a pin is broken), or where one or both of a pair of terminals are deformed (for example, a pin is bent). Furthermore, the male and female ends of these terminals can be either male or female, and the configuration is not limited to male terminals on the circuit board side and female terminals on the harness side.

[0114] <Regarding torque during brake control> When the power is on and there is no abnormality in the circuit, as described above, the CPU 304 controls the excitation state of each phase according to one of the excitation tables shown in Figure 10, depending on the rotation status of the reels 110 to 112 shown in Figure 11. Of these, the torque of the stepping motor 700 when brake control is performed (strong excitation by two phases of A and B) as shown in Figure 11 is called the brake torque. This brake torque is higher than the torque when reels 110 to 112 are accelerating (hereinafter referred to as acceleration torque) or when they are rotating at a constant speed (hereinafter referred to as constant speed torque), and the holding force of reels 110 to 112 is highest when brake control is performed compared to other states. Similarly, when the modified example shown in Figure 12 is used, the brake torque (four-phase excitation) is higher than the torque when reels 110 to 112 are accelerating (acceleration torque) or when they are rotating at a constant speed (constant speed torque), and the holding force of reels 110 to 112 is highest when brake control is performed compared to other states.

[0115] On the other hand, as explained above, when the power is turned off and there is no abnormality in the circuit configuration PT1 corresponding to coils LA, LB, LA-, and LB-, manually rotating reels 110 to 112 generates a load required for the rotation of reels 110 to 112 due to back electromotive force. At this time, the load generated by back electromotive force is the torque required when manually rotating reels 110 to 112 (the torque required for the rotation of the stepping motor 700), and this torque will be referred to as back electromotive force torque below. This back electromotive force torque increases in proportion to the change in current (speed) of reels 110 to 112. Furthermore, this back electromotive force torque is about the same magnitude as the torque corresponding to the operation (for example, acceleration torque or constant speed torque) when reels 110 to 112 are manually rotated and operated in the same way as during gameplay. The reason for assuming they are roughly the same is that the circuit conditions differ depending on whether power is supplied or not; for example, a capacitor that stores charge when power is supplied does not store charge when the power is turned off, and this affects the magnitude of the back electromotive force torque. For example, when reels 110 to 112 are rotated manually to achieve an acceleration similar to that in gameplay, the back electromotive force torque will be about the same magnitude as the acceleration torque and smaller than the braking torque (Figures 11 and 12, the same applies to both configurations).

[0116] Furthermore, when the power is turned off and there is a malfunction in the circuit configuration PT1 corresponding to coils LA, LB, LA-, and LB-, if reels 110-112 are rotated manually, no load due to back electromotive force will be generated (or the load will be reduced) in the faulty circuit. Note that when there is a circuit malfunction, the load due to back electromotive force is lower (or no load is generated) compared to when there is no circuit malfunction. For example, if reels 110-112 are rotated manually to achieve an acceleration similar to that in gameplay, the torque required for this rotation is smaller than the brake torque (Figures 11 and 12, the same applies to both configurations).

[0117] In the above configuration, the brake torque is greater than the back electromotive force torque when accelerating to the same degree as during gameplay, so even if the reels are accidentally rotated manually during brake control, malfunctions are less likely to occur.

[0118] <Regarding the load when the reel is manually rotated while the power is on> When the power is on and there is no abnormality in the circuit configuration PT1 corresponding to coils LA, LB, LA-, and LB-, the CPU 304 controls the excitation state of each phase according to one of the excitation tables shown in Figure 10, according to the rotation status of reels 110 to 112 shown in Figure 11, as described above. Of these, the reel stop control in Figure 11 is a state set when not playing (before the start of play or after the end of play), and specifically, phases A and B are controlled to weak excitation, and phases A- and B- are controlled to a state of no excitation. In this state, the torque due to the weak excitation of phases A and B becomes a holding torque that resists external rotational force, and this holding torque causes reels 110 to 112 (stepping motor 700) to stop. This holding torque is lower than the torque during acceleration of reels 110 to 112 (acceleration torque) and the torque during constant speed rotation (constant speed torque).

[0119] In the reel stop control state, reels 110 to 112 can be manually rotated by applying a torque greater than the holding torque applied to them. When the power is off, manually rotating reels 110 to 112 generates a load due to back electromotive force. However, in the reel stop control state, the reel drive voltage (24V) is constantly applied to the coil of the stepping motor 700, so manually rotating reels 110 to 112 does not generate a load due to back electromotive force. In this situation, the induced electromotive force due to the manual rotation of the reels is lower than the power supply voltage (DC) (the voltage due to the induced electromotive force is only a few volts compared to the power supply voltage of 24V), and it is AC. In this case, the voltage due to the induced electromotive force is not sufficient to drive current against the power supply voltage, so no current flows due to the induced electromotive force, and no back electromotive force or load is generated due to this current. In other words, when reels 110-112 are manually rotated with the power off, an electromotive force of several volts is generated in the coil, which was 0V before rotation, and a back electromotive force is generated due to the current caused by this potential difference. On the other hand, when reels 110-112 are manually rotated with the power on, no current is generated due to the induced electromotive force in the coil, which was supplied with 24V, so no back electromotive force or load is generated. Furthermore, depending on the configuration of IC1, it is possible that the current required to drive the stepping motor 700 (current flowing through the transistor: weak excitation) is maintained inside IC1, while the current due to the induced electromotive force (current from the ground side) is cut off (circuit configuration PT1 does not hold for the induced electromotive force). That is, in the reel stop control state, the holding torque due to the weak excitation of phases A and B may become a load when manually rotating reels 110-112. Note that in the modified example in Figure 12, since the reel stop control state is an unexcited state, no load is generated when manually rotating reels 110-112. Thus, depending on the control and configuration of the transistors, no current is generated due to induced electromotive force, and no back electromotive force or load is generated when manually rotating reels 110-112.Furthermore, as mentioned above, if the system is configured to apply excitation when stopping the reels but then de-excite them afterward, the FETs inside the IC will be in an isolated state, thus preventing the circuit configuration PT1 from being established, and no load will be generated when reels 110-112 are rotated manually.

[0120] On the other hand, as explained above, when the power is turned off and there is no abnormality in the circuit configuration PT1 corresponding to coils LA, LB, LA-, and LB-, manually rotating reels 110 to 112 generates a load required for the rotation of reels 110 to 112 due to back electromotive force. At this time, the load generated by back electromotive force is the torque required when manually rotating reels 110 to 112 (the torque required for the rotation of the stepping motor 700), and this torque will be referred to as back electromotive force torque below. This back electromotive force torque increases in proportion to the change in current (speed) of reels 110 to 112. Furthermore, this back electromotive force torque is about the same magnitude as the torque corresponding to the operation (for example, acceleration torque or constant speed torque) when reels 110 to 112 are manually rotated and operated in the same way as during gameplay. The reason for assuming they are roughly the same is that the circuit conditions differ depending on whether power is supplied or not. For example, a capacitor that stores charge when power is supplied does not store charge when the power is turned off, and this affects the magnitude of the back electromotive force torque. For example, when the power is turned off, if reels 110 to 112 are rotated manually to achieve an acceleration similar to that in gameplay, the back electromotive force torque will be about the same magnitude as the acceleration torque, and will be greater than the holding torque (the load when reels 110 to 112 are rotated manually in the reel stop control state).

[0121] <Comparison of harness disconnected state and harness connected state with power on> As explained above in "<Operation when the reel is manually rotated with the power off (1)>" and "<Load when the reel is manually rotated with the power on>", the load (weight) when the reel is rotated by external force (manual operation in the above explanation) is light in both the harness-disconnected state and the harness-connected state with the power on (energized) (compared to the harness-connected state with the power off). However, the load may differ between the two due to the different circuit conditions.

[0122] When the harness is not connected, no circuit configuration is established (for example, in Figure 14, circuit configuration PT1 is not established), and therefore it is not affected by current or voltage compared to when the harness is connected. The load in this state is referred to as the "first lightest load."

[0123] On the other hand, when the harness is connected and power is supplied, the switching of the transistors (FETs) within the motor control IC is OFF when power is supplied (for example, the current between the source and drain is OFF). Therefore, the circuit configuration is the same as when the harness is not connected, but in reality, because the harness is connected, an L component (parasitic inductance) is generated due to the length of the harness and the bundling of the harness, which generates a small induced electromotive force, so the weight may be slightly heavier than the first lightness described above.

[0124] Furthermore, the lightness of the harness connection while powered on (the second lightness) also affects the excitation status of the reel when it is stopped. When stopping a rotating reel, it is stopped with 4-phase excitation or 1-2 phase strong excitation. These 4-phase excitations and strong excitations continue to output for a while even after the reel has stopped. This is to stabilize the stopping position and prevent it from shifting due to the reaction of stopping. After that, the 4-phase excitation is released and the reel becomes de-excited. The strong excitation also switches to weak excitation or de-excited. In this case, in a configuration where weak excitation is continuously output while the reel is stopped, this is to maintain the position even when stopped, and in this case the second lightness is heavier than the first lightness.

[0125] <Regarding operation when the reel is manually rotated with the power off (2)> The above explanation described how abnormalities can sometimes be detected by the load applied when reels 110-112 are manually rotated. Below, Figure 14 will be used to explain how abnormalities can be detected by actions other than load. Note that the following explanation will focus on the left reel 110, but the same principles apply to the other reels.

[0126] When the left reel 110 is rotated manually, the power generated in coils LA, LB, LA-, and LB- causes current to flow to LEDD1, and LEDD1 lights up. On the other hand, if there is an abnormality in the circuit configuration PT1 corresponding to coils LA, LB, LA-, and LB- (the circuit is not connected, or the resistance value is higher than normal), then even if the left reel 110 is rotated manually, no current will flow to LEDD1 in the faulty circuit.

[0127] From the above, it is possible to infer whether or not there is an abnormality in the circuit around the stepping motor 700 of the left reel 110 by observing the difference in the illumination pattern of LEDD1 when the left reel 110 is rotated manually.

[0128] As shown in Figure 13, the power supply voltages (5V, 24V) and ground of the main control board 300B and the power supply board 252B are connected, and an LED is provided between the 24V power supply and ground of the power supply board 252B. Therefore, when the left reel 110 is rotated manually, the same operation as LEDD1 shown in Figures 13 and 14 can be observed in the LED on the power supply board 252B. Thus, by observing the differences in the light emission patterns of these LEDs, it is possible to infer whether or not there is a malfunction in the circuit around the stepping motor 700 of the left reel 110. Furthermore, by observing the differences in the light emission patterns of the LEDs, it is possible to infer whether or not there is a malfunction in the harness or wiring between the boards on which they are located.

[0129] <Regarding the circuit board configuration (1)> In the example shown in Figure 13, a configuration was described in which circuit boards equipped with stepping motors 700 (left reel motor board 700BL, middle reel motor board 700BC, right reel motor board 700BR) and a circuit board equipped with ICs 1-3 that control the stepping motors 700 (main control board 300B) are connected by harnesses H3-H5. However, there are various configurations for circuit boards used in gaming machines, and the example in Figure 13 is not the only one. Below, we will describe an example using a circuit board different from that in Figure 13.

[0130] Figure 16 shows a configuration in which circuit boards equipped with stepping motors 700 (left reel motor board 700BL, middle reel motor board 700BC, right reel motor board 700BR) and a circuit board equipped with ICs 1-3 for controlling the stepping motors 700 (main control board 300B) are connected via a reel relay board 700BM1. Figure 17 is a simplified diagram of the circuit for controlling the stepping motor 700 on the left reel board 700BL in Figure 16.

[0131] Comparing Figure 14 and Figure 17, the combined configuration of harnesses H7 and H8 and the reel relay board 700BM1 in Figure 17 corresponds to harness H3 in Figure 14. In other words, if the board configuration is not considered, the circuits in Figures 13 and 14 are equivalent to the circuits in Figures 16 and 17. For example, in the circuits of Figures 13 and 14, it was explained that an abnormality in harness H3 (harness not connected, some wiring broken, terminals not in the correct connection position, etc.) can be inferred by manually rotating the reel. Similarly, in the circuits of Figures 16 and 17, an abnormality in harnesses H7 and H8 (harness not connected, some wiring broken, terminals not in the correct connection position, etc.) can be inferred by manually rotating the reel. Furthermore, since harnesses H8 to H10 are provided in a one-to-one relationship corresponding to each reel, similar to harnesses H3 to H5 in Figure 13, the multiple reels (reels 110 to 112) can be individually inspected by manually rotating them. On the other hand, harness H7 is a harness that consolidates the wiring of each reel (reels 110-112) in a one-to-one relationship. If harness H7 is not connected, a load will be generated when all reels (reels 110-112) are rotated manually, allowing for a simultaneous inspection. If some wiring is broken or some terminals are not connected in the correct position, no load will be generated when any of the corresponding reels are rotated manually. At this point, harnesses H8-H10 can also be inspected to narrow down which part is malfunctioning.

[0132] Figure 18 shows a configuration in which circuit boards equipped with stepping motors 700 (left reel motor board 700BL, middle reel motor board 700BC, right reel motor board 700BR) and a circuit board equipped with ICs 1-3 for controlling the stepping motors 700 (main control board 300B) are connected via the main connection board 300BM and the reel relay board 700BM2. Figure 19 is a simplified diagram of the circuit for controlling the stepping motor 700 on the left reel board 700BL in Figure 18.

[0133] Comparing Figure 14 and Figure 19, the difference is that capacitors C2 and C3, which were located on the main control board 300B in Figure 14, are located on the reel relay board 700BM2 in Figure 19. Also, Figure 19 differs in that capacitor C4 on the main connection board 300BM and IC4 on the reel relay board 700BM2 are present, which are not present in the circuit of Figure 14. Note that IC4 on the reel relay board 700BM2 is a buffer that holds the signal from IC1, and when no power supply voltage is supplied, it is in a conductive state due to parasitic capacitance and parasitic diodes, similar to IC1.

[0134] Although there are differences between Figure 14 and Figure 19 as described above, they are similar in that the circuit configuration PT1 is established, starting from the stepping motor 700 on the left reel 110 (more specifically from coils LA, LB, LA-, and LB-), passing through resistors R1 and LEDD1, capacitors C1 to C3, load component ZA, and then IC1 to reach the stepping motor 700. In other words, the circuit to the left of harness H15 in Figure 19 corresponds to the circuit to the left of harness H3 in Figure 14. For example, in the circuits of Figures 13 and 14, it was explained that an abnormality in harness H3 (harness not connected, some wiring broken, terminals not in the correct connection position, etc.) can be inferred by manually rotating the reel, but in the circuits of Figures 18 and 19, an abnormality in harnesses H15 and H14 (harness not connected, some wiring broken, terminals not in the correct connection position, etc.) can be inferred by manually rotating the reel.

[0135] Furthermore, in order to confirm whether or not the circuit configuration PT1 is established by manually rotating the reel, as in this embodiment, it is necessary that the circuit configuration PT1 is not established within the reel motor boards (left reel motor board 700BL, middle reel motor board 700BC, right reel motor board 700BR) on which the stepping motor 700 is installed. In other words, by establishing the circuit configuration PT1 across the reel motor board, the board located on the power supply side of the reel motor, and the harness connecting these boards, it is possible to check for abnormalities in the circuit boards and connecting harnesses. Note that even if the circuit configuration PT1 is completed within the reel motor board, if the circuit configuration is not established due to mounting defects or component damage, the resistance when manually rotating the reel will be lighter. However, in this case, only the abnormality of the reel motor board can be detected, and abnormalities in other harnesses, etc., cannot be detected. On the other hand, as in this embodiment, the circuit configuration PT1 is configured to span across the reel motor board, the board located on the power supply side of the reel motor, and the harness connecting these boards. This allows the user to notice that an abnormality has occurred somewhere in the reel motor board, the board located on the power supply side of the reel motor, or the harness connecting these boards, not only when the harness is inserted but also when the harness is inserted and feels light. This provides an opportunity to initiate inspections focusing on multiple components and prevents the power from being turned on while a potential abnormality is present.

[0136] The power supply board 252B, which is present in all three examples (Figures 13, 16, and 18), is for supplying power voltage (5V, 24V) and ground, and is connected to the power voltage (5V, 24V) and ground of the other boards via a harness. A capacitor is provided between the 24V power supply and ground on this power supply board 252B. Therefore, when the reels 110-112 are rotated manually with the power supply turned off, some of the current generated by the coil of the stepping motor 700 flows into this capacitor, and a charge is accumulated. At this time, if there is a problem with the harness of the power supply board 252B (harness H1 in Figure 13, harness H6 in Figure 16, harness H11 in Figure 18) (e.g., the harness (connector) is disconnected, a part of the wire is broken), but there is no problem with the other harnesses, then no back electromotive force is generated because no current flows through the capacitor on the power supply board 252B, and the load is smaller compared to when there is no problem with the harness. Furthermore, the same phenomenon occurs if there is a problem with harness H14 in the example shown in Figure 18. Also, in the example shown in Figure 18, if the reel relay board 700BM2 does not have a power supply path from the main connection board 300BM, and instead a harness powered by the power supply board 252B is directly connected, the same phenomenon as described above will occur if there is a problem with this directly connected harness. Therefore, depending on the capacitance of the capacitors provided on the power supply board 252B, it may be possible to infer a problem with the harness around the power supply board 252B (harness disconnection, some wiring breaks, terminals not in the correct connection position, etc.) by manually rotating the reel.

[0137] Furthermore, depending on the configuration of the elements and circuits, a power supply voltage other than the power supply voltage used for reel driving (for example, 24V in Figure 13; in other words, the driving voltage for analog circuits and analog signals such as motors) may be provided (for example, 5V in Figure 13; in other words, the driving voltage for digital circuits and digital signals such as ICs). In such a configuration, if elements such as resistors are provided between circuits with different power supply voltages, current (current due to induced electromotive force) caused by manual rotation of the reel when the power is turned off may flow through these elements such as resistors provided between the power supply voltages. In other words, the circuit configuration PT1 may include not only circuits that are intended to operate at the power supply voltage used for reel driving, but also other circuits.

[0138] As described above, regardless of the circuit board configuration, it is sometimes possible to detect abnormalities by manually rotating the reel.

[0139] <Regarding the circuit board configuration (2)> In addition to the circuit board configurations described in Figures 13 to 19, there are various other configurations for circuit boards used in gaming machines. Below, examples of various circuit board configurations will be explained using Figures 20 and 21. Figures 20 and 21 are block diagrams showing examples of connections between the motors that drive the left, middle, and right reels and various circuit boards. In Figures 20 and 21, the circles labeled "left," "middle," and "right" represent the respective motors that drive the left, middle, and right reels (hereinafter sometimes referred to as the left motor, middle motor, and right motor).

[0140] In Figure 20(a), the power supply unit shown on the far left is connected to the performance connection board and the reel relay board, respectively. The reel relay board is further connected to the main control board and the left motor, middle motor, and right motor, respectively. In this example, the power supply for driving the left motor, middle motor, and right motor is supplied via the route power supply unit → harness HN2 → reel relay board → harness HN1. In this case, harnesses HN1 and HN2 constitute part of the circuit for driving the motors.

[0141] In the above configuration, as explained in the example in Figure 13, when the reel is rotated manually with the power off, an electromotive force (EMF) is generated in the circuit for driving the motor, and a back EMF is generated that attempts to counteract the change caused by this EMF. This back EMF creates the load (feel, resistance, weight, difficulty in rotation) when the reel is rotated manually. However, if the circuit for driving one (or all) of the motors is not functioning due to factors such as harness HN1 or harness HN2 being disconnected or broken, the above-mentioned EMF, back EMF, and load will not be generated (or will be reduced) when the affected reel is rotated manually. By paying attention to the difference in load when rotating such reels, it is possible to detect connection abnormalities or damage to harness HN1 or harness HN2, or circuit abnormalities. Note that in this example, the harnesses connected to the motors are described separately, but the same applies when they are combined into a single harness (the same applies in the following examples).

[0142] In Figure 20(b), the power supply unit shown on the far left is connected to the power supply relay board, which in turn is connected to the performance control board and the main control board, respectively. The main control board is then connected to the left motor, middle motor, and right motor via the reel relay board. In this example, the power supply for driving the left motor, middle motor, and right motor is supplied via the following route: power supply unit → harness HN4 → power supply relay board → harness HN3 → main control board → harness HN2 → reel relay board → harness HN1. In this case, harnesses HN1 to HN4 constitute part of the circuit for driving the motors.

[0143] In the above configuration, as explained in the example in Figure 13, when the reel is rotated manually with the power off, an electromotive force (EMF) is generated in the circuit for driving the motor, and a back EMF is generated that attempts to counteract the change caused by this EMF. This back EMF creates the load (resistance, weight, difficulty in rotation) when the reel is rotated manually. However, if the circuit for driving one (or all) of the motors is not functioning due to factors such as one of the harnesses HN1 to HN4 being disconnected or broken, the above-mentioned EMF, back EMF, and load will not be generated (or will be reduced) when the affected reel is rotated manually. By paying attention to these differences in load when the reel is rotated, it is possible to detect connection abnormalities or damage to harnesses HN1 to HN4, or circuit abnormalities.

[0144] Furthermore, even if a configuration is adopted in which the reel relay board and harness HN2 are absent, and the main control board is connected to the left motor, middle motor, and right motor via harness HN1, it is still possible to detect connection abnormalities or damage to harnesses HN1, HN3, and HN4, as well as circuit abnormalities, by focusing on the differences in load when the reel is rotated.

[0145] In Figure 20(c), the power supply unit shown on the far left is connected to the power supply relay board, which in turn is connected to the main control board. The main control board is then connected to the performance control board and the reel relay board, respectively. The reel relay board is connected to the left motor, middle motor, and right motor, respectively. In this example, the power to drive the left motor, middle motor, and right motor is supplied via the following route: power supply unit → harness HN4 → power supply relay board → harness HN3 → main control board → harness HN2 → reel relay board → harness HN1. In this case, harnesses HN1 to HN4 constitute part of the circuit for driving the motors.

[0146] In the above configuration, as explained in the example in Figure 13, when the reel is rotated manually with the power off, an electromotive force (EMF) is generated in the circuit for driving the motor, and a back EMF is generated that attempts to counteract the change caused by this EMF. This back EMF creates the load (resistance, weight, difficulty in rotation) when the reel is rotated manually. However, if the circuit for driving one (or all) of the motors is not functioning due to factors such as one of the harnesses HN1 to HN4 being disconnected or broken, the above-mentioned EMF, back EMF, and load will not be generated (or will be reduced) when the affected reel is rotated manually. By paying attention to these differences in load when the reel is rotated, it is possible to detect connection abnormalities or damage to harnesses HN1 to HN4, or circuit abnormalities.

[0147] In Figure 21(d), the power supply unit shown on the far left is connected to the performance control board and the main control board, respectively. The main control board is further connected to the medal count control board and the reel relay board, with the reel relay board being connected to the left motor, middle motor, and right motor, respectively. In this example, the power to drive the left motor, middle motor, and right motor is supplied via the route: power supply unit → harness HN3 → main control board → harness HN2 → reel relay board → harness HN1. At this time, harnesses HN1 to HN3 constitute part of the circuit for driving the motors.

[0148] In the above configuration, as explained in the example in Figure 13, when the reel is rotated manually with the power off, an electromotive force is generated in the circuit for driving the motor, and a back electromotive force is generated that attempts to counteract the change caused by this electromotive force. This back electromotive force creates the load (feel, resistance, weight, difficulty in rotation) when the reel is rotated manually. However, if the circuit for driving one (or all) of the motors is not functioning due to factors such as one of the harnesses HN1 to HN3 being disconnected or broken, the electromotive force, back electromotive force, and load will not be generated (or will be reduced) when the affected reel is rotated manually. By paying attention to these differences in load when the reel is rotated, it is possible to detect connection abnormalities or damage to harnesses HN1 to HN3, or circuit abnormalities.

[0149] In Figure 21(e), the power supply unit shown on the far left is connected to the performance connection board and the motor drive board, respectively. The motor drive board is further connected to the main control board and the reel relay board, of which the reel relay board is connected to the left motor, middle motor, and right motor, respectively. In this example, the power to drive the left motor, middle motor, and right motor is supplied via the route: power supply unit → harness HN3 → motor drive board → harness HN2 → reel relay board → harness HN1. In this case, harnesses HN1 to HN3 constitute part of the circuit for driving the motors.

[0150] In the above configuration, as explained in the example in Figure 13, when the reel is rotated manually with the power off, an electromotive force is generated in the circuit for driving the motor, and a back electromotive force is generated that attempts to counteract the change caused by this electromotive force. This back electromotive force creates the load (feel, resistance, weight, difficulty in rotation) when the reel is rotated manually. However, if the circuit for driving one (or all) of the motors is not functioning due to factors such as one of the harnesses HN1 to HN3 being disconnected or broken, the electromotive force, back electromotive force, and load will not be generated (or will be reduced) when the affected reel is rotated manually. By paying attention to these differences in load when the reel is rotated, it is possible to detect connection abnormalities or damage to harnesses HN1 to HN3, or circuit abnormalities.

[0151] In Figure 21(f), the power supply unit shown on the far left is connected to the performance connection board and the power relay board, respectively. The power relay board is further connected to the main connection board and the medal count control board. The main connection board is connected to the main control board and to the left motor, middle motor, and right motor, respectively. In this example, the power to drive the left motor, middle motor, and right motor is supplied via the route: power supply unit → harness HN3 → power relay board → harness HN2 → main connection board → harness HN1. In this case, harnesses HN1 to HN3 constitute part of the circuit for driving the motors.

[0152] In the above configuration, as explained in the example in Figure 13, when the reel is rotated manually with the power off, an electromotive force is generated in the circuit for driving the motor, and a back electromotive force is generated that attempts to counteract the change caused by this electromotive force. This back electromotive force creates the load (feel, resistance, weight, difficulty in rotation) when the reel is rotated manually. However, if the circuit for driving one (or all) of the motors is not functioning due to factors such as one of the harnesses HN1 to HN3 being disconnected or broken, the electromotive force, back electromotive force, and load will not be generated (or will be reduced) when the affected reel is rotated manually. By paying attention to these differences in load when the reel is rotated, it is possible to detect connection abnormalities or damage to harnesses HN1 to HN3, or circuit abnormalities.

[0153] In Figures 20 and 21, the harnesses that make up the circuit for driving the motors are indicated with reference numerals. Harnesses that do not have reference numerals do not make up the circuit for driving the motors, so even if any of them are disconnected or broken, there will be no difference in the load when the reel is rotated. For example, in Figures 20(a) and 21(f), the left motor, middle motor, and right motor, and the main control board, each receive power from the same board (the reel relay board in Figure 20(a), and the main connection board in Figure 21(f)), and the left motor, middle motor, and right motor and the main control board are in a parallel relationship (they are all connected to the same board, they are not in a hierarchical relationship in a tree structure with the power supply at the top, they are not in a power supply and receiving relationship, and they are not on the power supply line). In such a relationship, even if the harness on the main control board side is disconnected, there will be no difference in the load when the reel is rotated.

[0154] Figures 20 and 21 illustrate how a malfunction in the harness constituting the circuit for driving the motor can result in a difference in the load when the reel is rotated. However, depending on the circuit configuration, a malfunction in the harness may not significantly affect the load when the reel is rotated. This point will be explained below using Figure 22. Figure 22 is a simplified diagram showing the circuit for driving the motor (hereinafter referred to as the motor drive circuit).

[0155] In Figure 22(a), the motor on the right is driven by the power supply on the left. When the power is off, manually rotating the reel (motor) generates electromotive force and back electromotive force in the motor drive circuit, creating a load. If the circuit is broken at the point indicated by the dotted line CL, the motor will not be driven, and since the circuit is not established, no electromotive force or back electromotive force will be generated, and no load will be created. The case where an abnormality occurs in the labeled harness in Figures 20 and 21 basically corresponds to the case where the circuit is broken at the point indicated by the dotted line CL in Figure 22(a).

[0156] Figure 22(b) shows the circuit in Figure 22(a) with an additional path added to connect to component S. For example, if a separate control IC is provided in addition to the power supply, a capacitor may be provided together to ensure the operating voltage of this control IC. Component S is a general indication that such a component is provided and is not limited to a capacitor.

[0157] In Figure 22(b), similar to Figure 22(a), the motor on the right is driven by the power supply on the left. When the power supply is off, manually rotating the reel (motor) generates electromotive force and back electromotive force in the motor drive circuit, creating a load. If the circuit is interrupted at the point indicated by the dotted line CL (on the power supply side of component S, upstream of component S), the motor will not drive. However, when the reel (motor) is rotated manually, a separate circuit consisting of the motor and component S (hereinafter referred to as the abnormal circuit) is established, and electromotive force and back electromotive force are generated in this abnormal circuit, creating a load. Note that the load generated in the abnormal circuit is different from that when the motor drive circuit is established.

[0158] The motor drive circuit is designed to ensure sufficient current to drive the motor, but this current is not always guaranteed in the malfunction circuit. For example, a relatively large capacitor (e.g., an electrolytic capacitor) may be included to stabilize the operation of the control IC. If component S is a large capacitor, it can supply sufficient current, and the load on the malfunction circuit will be similar to that of the reel drive circuit when it is functioning correctly.

[0159] For example, if the reel relay board (main connection board in Figure 21(f)) in Figures 20 and 21 contains large capacitors or control ICs, the abnormal circuit shown in Figure 22(b) may be activated when the harness HN2 is disconnected, potentially causing a load when the reel is rotated manually.

[0160] In contrast, if the reel relay board (main connection board in Figure 21(f)) in Figures 20 and 21 does not have a large-capacity capacitor or control IC, the situation in Figure 22(a) occurs, and when the harness HN2 is disconnected, there may be no load when the reel is rotated manually, or the abnormal circuit in Figure 22(b) is established, but the load when the reel is rotated manually is small. In this case, a certain board located on the power supply side (upstream side / input side) of the reel relay board is equipped with a large-capacity capacitor, control IC, and components necessary for generating the power supply voltage. In Figure 20(a), this certain board corresponds to the board equipped with the power supply generation circuit in the power supply unit. In Figures 20(b) and (c), this corresponds to the main control board, the power relay board, or the board equipped with the power supply generation circuit in the power supply unit. In Figure 21(d), this corresponds to the main control board or the board equipped with the power supply generation circuit in the power supply unit. Figure 21(e) corresponds to a motor drive board or a board equipped with a power generation circuit in a power supply unit. Figure 21(f) corresponds to a power relay board or a board equipped with a power generation circuit within a power supply unit.

[0161] <Regarding the load and power supply status when the reel is rotated manually> The relationship between the duration of load generated when the reel is rotated manually and the power supply status will be explained below using Figure 23. Figure 23 shows how the magnitude of the load changes when the reel is rotated manually in response to changes in the power supply status.

[0162] Figure 23 shows the changes that occur when the power switch is turned from ON to OFF, causing the drive voltage of the reel drive circuit to drop from 24V to 0V, and then when the power switch is turned from OFF to ON, causing the drive voltage of the reel drive circuit to increase from 0V to 24V. Figure 23 also shows that the 24V monitor lamp (a lamp indicating the drive voltage status) gradually turns off (brighter) as the drive voltage drops from 24V to 0V, and then gradually lights up (brighter) as the drive voltage increases from 0V to 24V.

[0163] When the power switch is ON, the power supply voltage (24V) is supplied to the reel drive circuit, so the drive voltage is 24V. In this case, even if the reel is rotated manually, the current is controlled by the control IC (switching element, transistor, etc.), so no load is generated (or the load is small), as explained above (see <Load when the reel is rotated manually with the power on>).

[0164] When the power switch is turned OFF (no power supply voltage is available), the charge stored in the capacitor is supplied to the reel drive circuit. As this charge is released, the drive voltage gradually decreases. Even if the drive voltage drops slightly at this time, the control IC of the reel drive circuit can operate as long as it is above the stable drive voltage. Figure 23 shows the period during which the drive voltage is above this stable drive voltage (the period when it is the first voltage). During this period, even if the reel is rotated manually, the current is controlled by the control IC, so no load is generated (or the load is small).

[0165] Figure 23 shows the period during which the drive voltage is below the stable drive voltage (the period of the second voltage). When the drive voltage falls below the stable drive voltage, the control IC stops operating (normal operation becomes impossible). Furthermore, the CPU of the main control unit also stops operating (the program stops due to the voltage drop), so the control IC becomes uncontrolled. Note that, for the CPU of the main control unit, if the voltage drops further than the voltage at which the program stops, it may output a reset signal to the control IC, and upon receiving this reset signal, the control IC stops operating. In this way, the control IC changes to a state where it is not controlling the current, and a load gradually occurs when the reel is rotated manually. Also, as the charge stored in the capacitor decreases, current flows more easily, and the load when the reel is rotated manually gradually increases. In this example, the load increases sharply in the latter half of the period of the second voltage, and this change is an example of a change caused by a decrease in the charge stored in the capacitor.

[0166] Furthermore, Figure 23 shows that the drive voltage has become 0V. At this time, the control IC is not operating (switching elements, transistors, etc.; FETs are in a conductive state), and when the reel is rotated manually, an electromotive force is generated in the circuit for driving the motor, and a back electromotive force is also generated that tries to counteract the changes caused by this electromotive force. This back electromotive force creates the load (resistance, resistance, weight, difficulty in rotation, reverse torque) when the reel is rotated manually. This operation is as explained above (see <Operation when the reel is rotated manually with the power off (1)>). Figure 23 shows that the above load is at its maximum during the period when the drive voltage is 0V.

[0167] As described above, when the power switch is turned OFF, the load when manually rotating the reel gradually increases. In this example, the 24V monitor lamp indicates that the operation has completely stopped, but by checking the load when manually rotating the reel, it is possible to confirm that it has completely stopped, allowing for safer disassembly and replacement work. In addition, as the 24V monitor lamp gradually goes out, the load when manually rotating the reel also changes, allowing for visual confirmation. Even if the degree to which the 24V monitor lamp is off and the change in the load when manually rotating the reel do not necessarily coincide, it can still be used as an indicator that the charge has decreased, and checking both the 24V monitor lamp and the feel when manually rotating the reel allows for even safer disassembly and replacement work. Furthermore, when the power switch is turned ON, as will be described later, the degree of charge accumulation and the increase in voltage can be confirmed by the degree to which the 24V monitor lamp is lit and the change in the load when manually rotating the reel, which is the same method.

[0168] Next, the power switch is turned ON (power voltage is supplied), and the drive voltage rises. Figure 23 shows the period when the drive voltage is below the stable drive voltage (the period of second voltage). During this period, as the drive voltage approaches the stable drive voltage, charge is accumulated in the capacitor, and as it charges, current stops flowing, gradually reducing the load when the reel is rotated manually. Also during this period, the control IC gradually starts to operate, and when the CPU of the main control unit starts operating, the control IC enters a state where it controls the current (the FET becomes in an isolated state). As the control IC changes to a state where it controls the current in this way, the load when the reel is rotated manually gradually disappears. In this example, the load decreases sharply in the latter half of the period of second voltage, but this change is an example of a change caused by the control IC starting to operate normally.

[0169] Furthermore, Figure 23 shows the period during which the drive voltage is equal to or greater than the stable drive voltage (the period when it is the first voltage). During this period, the control IC of the reel drive circuit operates normally and controls the current, so even if the reel is rotated manually, no load is generated (or only a small load).

[0170] <Regarding the operating noise caused by the load when manually rotating the reel> In the previous examples, we explained that when a reel is rotated manually, a load (feel, resistance, weight, difficulty in rotation) is generated depending on the state of the power supply and the circuit. This load is not constant with respect to the rotation of the reel, but fluctuates periodically due to the so-called cogging torque caused by the structure of the motor. This fluctuation in load causes the motor to vibrate and produce operating noise. In configurations where a gear is provided between the reel and the motor, the gear operates and produces noise when the reel is rotated manually, and the greater the load, the stronger the gear meshing becomes, resulting in louder gear operating noise. Furthermore, changes in the magnetic field generated within the motor can cause vibrations in the coils, etc., which can also produce operating noise. The magnitude of these operating noises changes with the magnitude of the load; the smaller the load, the quieter the operating noise, and the larger the load, the louder the operating noise. The pitch of these operating noises may also change with the magnitude of the load; the pitch is higher with a lower load, and lower with a higher load. Furthermore, it is preferable that the external force applied to the reel (motor) remains constant, regardless of whether the load is high (e.g., when the power is off) or low (e.g., when the power is on). This is because the operating sound may change depending on the power supply status and harness connection status, and applying a constant external force allows for more accurate detection of the energization status and any abnormalities. As for the "constant external force," if the stepping motor is moved by one step using external force, the difference in load may be felt tactilely, but the operating sound may be small. Therefore, an external force that moves the reel half a rotation at the reel's steady rotation speed (79 rotations per minute, 750ms per rotation) may also be used. Alternatively, a string with a weight of a certain weight attached and hanging downwards from the reel can also be used to apply a constant external force. However, since the load is generated when circuit configuration PT1 is established or not, the operating sound will change even if the external force applied to the reel (motor) is not constant, so it is possible to detect the energization status and any abnormalities, and the same effect can be achieved.Thus, the motor's operating sound changes depending on the load (feel, resistance, weight, difficulty in rotation, reverse torque) generated when the reel is rotated manually. Therefore, even if the operator has difficulty feeling the resistance when manually rotating the reel, they can determine whether the motor is powered on or if there is a problem based on the motor's operating sound. This applies not only to reels but also to other movable display devices (movable parts).

[0171] Furthermore, the loads (feel, resistance, weight, difficulty in rotation, reverse torque) generated when manually rotating the reels, as explained above, apply equally to any of the left, middle, and right reels (the relationships are the same). Similarly, the operating noise, the amount of movement due to inertia, and the time it takes to stop from inertia, all resulting from differences in load, also apply equally to any of the reels (the relationships are the same). For example, by manually rotating all three reels simultaneously and determining the feel, inspection time can be shortened.

[0172] <Regarding the motor type> The stepping motor 700 in the above embodiment uses a so-called unipolar motor, but a bipolar motor may also be used. The following explanation will be given with reference to Figures 24 and 25. Figure 24 is a diagram showing a modified version of Figure 14. Figure 25 is a diagram showing the internal configuration of IC1 in Figure 24.

[0173] The modified version shown in Figure 24 replaces the unipolar motor used in Figure 14 with a bipolar motor. In this modified version, IC1 is replaced with one that controls the bipolar motor. In a bipolar motor, the A-phase and A-phase pair are controlled by a common coil LA (LA-), and the B-phase and B-phase pair are controlled by another common coil. The coil controlling the B-phase and B-phase is controlled in the same way as the coil LA for the A-phase and A-phase. Therefore, the coil controlling the B-phase and B-phase is not shown in the diagram, and the excitation of the A-phase and A-phase will be explained below using Figure 25.

[0174] Figure 25 shows transistors TR21, TR22, TR23, and TR24 located inside IC1. When the A phase is excited, transistors TR21 and TR24 are controlled to be on, and transistors TR22 and TR23 are controlled to be off. Conversely, when the A- phase is excited, transistors TR21 and TR24 are controlled to be off, and transistors TR22 and TR23 are controlled to be on. This control reverses the direction of the current when exciting the A phase and when exciting the A- phase (see arrows in Figure 25). In other words, the A phase and A- phase are controlled by reversing the magnetic field of coil LA.

[0175] Next, we will explain the case where the power is off and there is no abnormality in the circuit (i.e., the connectors and harnesses are properly connected). In this case, when the left reel 110 is rotated manually, an electromotive force is generated sequentially in the A-phase (A-phase) coil LA and the B-phase (B-phase) coil due to electromagnetic induction, and a current flows in the opposite direction to when the reel is driven (counterclockwise from the stepping motor 700 in Figure 24). Specifically, as shown by the dotted arrows (1) to (7) in Figure 25, a circuit configuration PT1 is established in which current flows from the stepping motor 700 of the left reel 110, through the inside of IC1, through the wiring on the 24V power supply side, through the components R1 and LEDD1, capacitor CA, and load component ZA, and then through the wiring on the ground side, again through the inside of IC1, to the stepping motor 700. Current flows through this circuit configuration PT1. The current path inside IC1 will be explained below using Figure 25.

[0176] Transistors TR21, TR22, TR23, and TR24 located inside IC1 have so-called parasitic diodes and parasitic capacitances (physical configurations equivalent to diodes and capacitors in terms of structure) that are not located inside IC1. In Figure 25, these parasitic diodes PD21, PD22, PD23, and PD24, and parasitic capacitances PC21, PC22, PC23, and PC24 are shown as dotted lines. When the left reel 110 is rotated manually, the path of the current inside IC1 that exits from coil LA to the 24V power supply is formed by parasitic diode PD21 (or parasitic diode PD22). Also, the path of the current inside IC1 that returns from the ground side to coil LA is formed by parasitic diode PD24 (or parasitic diode PD23). Depending on the type of IC, there may be a voltage-resistant protection diode to protect the transistor from back electromotive force, in which case the current path is formed by this voltage-resistant protection diode.

[0177] As described above, when using a bipolar motor, just like when using a unipolar motor, if the reel is rotated manually with the power off, a current due to electromagnetic induction flows through the circuit configuration PT1. Furthermore, as in the example in Figure 14, a load is also generated when the reel is rotated manually. Thus, the operation when the reel is rotated manually, as described above, is independent of the type of motor, and therefore, regardless of the type of motor, it may be possible to detect abnormalities by observing the operation when the reel is rotated manually.

[0178] <Regarding the case where moving parts other than the reel are operated manually> The above explanation describes how abnormalities can sometimes be detected by observing the operation of reels 110-112 when they are rotated manually. In addition to reels 110-112, gaming machines may also have other movable parts that are operated by motors. In the case of such movable parts, if the circuit configuration is like that of circuit PT1 in Figure 14, manually operating them will generate induced electromotive force or back electromotive force in the motor, and abnormalities can sometimes be detected by observing this operation.

[0179] For example, Figure 13 shows that the medal dispensing device 180 is equipped with a motor. The medal dispensing device 180 has a hopper that is operated by the motor, and abnormalities can sometimes be detected by the difference in load or the difference in the illumination pattern of the LED when this hopper is operated manually.

[0180] Furthermore, for example, if a system is used in which movable parts for performances are driven by motors, abnormalities can sometimes be detected in the same way as described above by observing the operation of these movable parts when they are operated manually. This will be explained below using Figure 26.

[0181] Figure 26 shows the performance control board 400B on the left, the harness H21 connecting the performance control board 400B to the power supply board 252B, and the performance movable body relay board 400BM connected by harness H22. Further on the right side of the figure, the motor board 400BL connected to the performance movable body relay board 400BM by harness H23 is shown.

[0182] The performance control board 400B is the board corresponding to the first sub-control unit 400 in Figure 4. Note that some components and wiring are omitted in the diagram. The first sub-control unit 400 is shown to contain the CPU 404 in Figure 4, which outputs various control signals. Figure 26 shows that wiring is provided from the CPU 404 to IC 424a to output a drive signal for the movable body. This IC 424a corresponds to the drive circuit 424 in Figure 4 and controls the stepping motor 700 of the movable body according to the signal from the CPU 404. Figure 26 shows that the wiring from IC 424a is connected to the terminals of the stepping motor 700 of the movable body.

[0183] The stepping motor 700 in Figure 26 is a so-called bipolar type, and is equipped with coil LsA corresponding to phase A and A-, and coil LsB corresponding to phase B and B-. In Figure 26, drive signals Φ0 and Φ1 are input / output terminals for signals that control the excitation of coil LsA, and drive signals Φ2 and Φ3 are input / output terminals for signals that control the excitation of coil LsB. When current flows from drive signal Φ0 to drive signal Φ1, phase A is excited, and when current flows from drive signal Φ1 to drive signal Φ0, phase A- is excited. Similarly, when current flows from drive signal Φ2 to drive signal Φ3, phase B is excited, and when current flows from drive signal Φ3 to drive signal Φ2, phase B- is excited.

[0184] When IC424a receives an A-phase excitation signal from CPU404, it controls the current to flow from drive signal Φ0 to drive signal Φ1, and when it receives an A-phase excitation signal, it controls the current to flow from drive signal Φ1 to drive signal Φ0. Furthermore, when IC424a receives a B-phase excitation signal from CPU404, it controls the current to flow from drive signal Φ2 to drive signal Φ3, and when it receives a B-phase excitation signal, it controls the current to flow from drive signal Φ3 to drive signal Φ2.

[0185] Figure 26 also shows a resistor Rs1 and LEDDs1 connected in series between the 5V power supply and ground of the 400B performance control board. Of these, LEDDs1 is responsible for indicating that the power is on by emitting light. Figure 26 also shows that there are several capacitors (e.g., capacitors Cs1 and Cs2) provided to stabilize the operation and remove noise.

[0186] In the circuit shown in Figure 26, the case where the power is off and there is no abnormality in the circuit (connectors and harnesses are properly connected) will be explained. In this case, when the movable body is rotated manually, an electromotive force is generated in coils LsA and LsB due to electromagnetic induction, and a current flows in the opposite direction to when the movable body is driven. Specifically, a circuit configuration PS1 is established in which current flows from the coils of the stepping motor 700 of the movable body (more specifically coils LsA and LsB), along the wiring of the drive signal Φ0, through resistor Rs2 and bead Ls1 to IC424a, then through the inside of IC424a, through the wiring on the 5V power supply side, through resistor Rs1 and LEDDs1, and then from the ground side, again through the inside of IC424a, along the wiring of the drive signal Φ1, through bead Ls1 and resistor Rs2 to the stepping motor 700, and current flows through this circuit configuration PS1.

[0187] As described above, when using a movable body, just like with a reel, if the movable body is rotated manually with the power off, a current due to electromagnetic induction flows to circuit configuration PS1. Furthermore, as in the example in Figure 14, a load is also generated when the movable body is rotated manually.

[0188] If there is an abnormality in the circuit configuration PS1 shown in Figure 26 above (the circuit is not connected, the resistance value is higher than normal, or the connector or harness is not properly connected), the same phenomenon will occur as when there is an abnormality in the circuit configuration PT1 shown in Figures 13 and 14. For example, if harnesses H22 and H23 are disconnected, no back electromotive force or load will be generated in any of the circuits connected to coils LsA and LsB when the movable body is operated manually. If harnesses H22 and H23 are not disconnected, back electromotive force will be generated in the circuits connected to coils LsA and LsB when the movable body is operated manually, resulting in a greater load than when harnesses H22 and H23 are disconnected. This difference in load may indicate that there is an abnormality in the circuit around the motor of the movable body.

The first connection state is defined as the state in which the first connector and the second connector are connected and the plurality of terminals are in their normal connection positions.

[0206] Furthermore, the gaming machines described above, The aforementioned predetermined substrate is a substrate on which the first component (for example, resistor R1, LEDD1, capacitor CA, load component ZA, IC1 in Figure 14) is arranged. In the first state described above, a circuit configuration (for example, circuit configuration PT1 in Figure 14) is established that leads from the motor through the first component to the motor. In the second state described above, the circuit configuration is not established. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0207] Furthermore, in the above explanation, A gaming machine equipped with movable parts (e.g., reels 110-112) that can be operated by the drive of a motor, The aforementioned gaming machine is equipped with a predetermined circuit board (for example, the main control board 300B in Figure 13, see <About the circuit board configuration> for other components), The motor is electrically connected to the predetermined circuit board via a harness (for example, harnesses H3 to H5 in Figure 13, see also <Regarding the configuration of the circuit board>). The state in which the predetermined circuit board and the harness are electrically connected is defined as the connected state. The state in which the predetermined circuit board and the harness are not electrically connected is defined as the disconnected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off. The state in which the connection is made and power is supplied to the gaming machine is defined as the second state. The aforementioned disconnected state and the power supply to the gaming machine being cut off are defined as the third state. In the first state and the second state, the load on the manual operation of the movable body is different. In the first state and the third state, the load on the manual operation of the movable body is different. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0208] Furthermore, the gaming machines described above, The first state presents a greater load on the manual operation of the movable body than the second state presents. The first state presents a greater load on the manual operation of the movable body than the third state presents. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0209] Also, the gaming machine described above, where the predetermined substrate is a substrate on which first components (e.g., resistor R1, LED D1, capacitor CA, load component ZA, IC1 in FIG. 14) are arranged, in the connected state, a circuit configuration (e.g., circuit configuration PT1 in FIG. 14) from the motor, through the first components, and back to the motor is established, in the non-connected state, the circuit configuration is not established, A gaming machine (for example, refer to <Operation when the reel is manually rotated with the power off (1)>) having the above characteristics has been described.

[0210] Also, in the above description, a gaming machine having reels (e.g., reels 110 to 112) operable by driving a motor, where the gaming machine includes a first substrate (e.g., main control substrate 300B in FIG. 13, refer to <Configuration of the substrate (1)> and <Configuration of the substrate (2)>) that can be electrically connected to the motor, a state in which the first substrate and the motor are electrically connected is defined as a connected state, a first state is defined as a power-off state where the gaming machine is in the connected state and the power supply to the gaming machine is cut off, a second state is defined as a power supply state where the gaming machine is in the connected state and the power supply to the gaming machine is on, when the reel is manually operated in the forward rotation direction in the second state, the weight is lighter than when the reel is manually operated in the forward rotation direction in the first state, when the reel is manually operated in the reverse rotation direction in the second state, the weight is lighter than when the reel is manually operated in the reverse rotation direction in the first state, A gaming machine (for example, refer to <Operation when the reel is manually rotated with the power off (1)> and <Load when the reel is manually rotated with the power on>) having the above characteristics has been described.

[0211] In this gaming machine, there is a difference in load in either the forward or reverse rotation direction of the reel. Therefore, when an operator moves the reel for confirmation, the operation direction of the reel is not limited to one direction, making the confirmation work easier. Also, even if the operator's clothing or tools accidentally touch the reel, the weight of the reel is light and it rotates easily, so it can deflect the force applied to the reel without resisting it, making it less likely to cause a malfunction.

[0212] Also, for the gaming machine described above, a state where the first substrate and the motor are not electrically connected is defined as a non - connected state, a power - off state where the power supply to the gaming machine is cut off in the non - connected state is defined as a third state, the weight when the reel is operated by an external force in the forward rotation direction in the third state is lighter than the weight when the reel is operated by an external force in the forward rotation direction in the first state, the weight when the reel is operated by an external force in the reverse rotation direction in the third state is lighter than the weight when the reel is operated by an external force in the reverse rotation direction in the first state, A gaming machine characterized by this (for example, refer to <Regarding the operation when the reel is manually rotated with the power off (1)>) has been described.

[0213] Also, for the gaming machine described above, the gaming machine further includes a second substrate that can be electrically connected to the first substrate, in the first state, the weight when the reel is operated by an external force when the first substrate and the second substrate are electrically connected is heavier than the weight when the reel is operated by an external force when the first substrate and the second substrate are not electrically connected, A gaming machine characterized by this (for example, refer to <Regarding the configuration of the substrate (1)>, <Regarding the configuration of the substrate (2)>) has been described.

[0215] Furthermore, in the above explanation, A gaming machine equipped with multiple reels (for example, reels 110 to 112) corresponding to multiple motors, Each of the aforementioned multiple reels is operable by the drive of the corresponding motor among the aforementioned multiple motors, The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the plurality of motors, The state in which the first substrate and the plurality of motors are electrically connected is defined as the connected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off. The state in which the connection is made and power is supplied to the gaming machine is defined as the second state. In the aforementioned plurality of reels, the weight when operated by an external force in the second state is lighter than the weight when operated by an external force in the first state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

Furthermore, even if an operator's clothing or tools unintentionally touch the reels, the light weight and ease of rotation of the multiple reels allow them to absorb the force without resisting it, thus reducing the likelihood of malfunction.

[0217] Furthermore, the gaming machines described above, The state in which the first substrate and the plurality of motors are not electrically connected is defined as the disconnected state. The aforementioned disconnected state and the power supply to the gaming machine being cut off are defined as the third state. In the aforementioned plurality of reels, the weight when operated by an external force in the third state is lighter than the weight when operated by an external force in the first state. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0218] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the plurality of reels, the weight when the reels are operated by an external force when the first circuit board and the second circuit board are not electrically connected in the first state is lighter than the weight when the reels are operated by an external force when the first circuit board and the second circuit board are not electrically connected in the first state. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0219] Furthermore, the gaming machines described above, The first substrate is a substrate that receives power from the second substrate. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0220] Furthermore, in the above explanation, A gaming machine equipped with reels (e.g., reels 110-112) that can be operated by motor drive, The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the motor, The state in which the first substrate and the motor are electrically connected is defined as the connected state. The first state is defined as the power-off state in which the connection is made and the power supply to the gaming table is cut off. The second state is defined as the power supply state in which the connection is made and the power supply to the gaming table is on. The operating sound when the reel is operated by an external force in the first state is different from the operating sound when the reel is operated by an external force in the second state. This describes a gaming table (for example, refer to <Regarding the operation when the reel is manually rotated with the power off (1)>, <Regarding the load when the reel is manually rotated with the power on>, <Regarding the operating sound associated with the load when the reel is manually rotated>), characterized by the above.

[0221] In this gaming table, it is possible to easily detect abnormalities from the difference in the operating sound when the reel is rotated. Also, if the clothing or tools worn by the operator accidentally touch the reel, the operating sound of the reel may allow the operator to notice the contact.

This describes a gaming table (for example, refer to <Regarding the operation when the reel is manually rotated with the power off (1)>, <Regarding the load when the reel is manually rotated with the power on>), characterized by the above.

[0224] Furthermore, the gaming machines described above, The operating sound is higher pitched or lower pitched in the second state than in the first state. A gaming machine characterized by the above (see, for example, <Regarding the operating noise associated with the load when the reels are rotated manually>) was described.

[0225] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the first state described above, the weight of the reel when it is operated by an external force when the first substrate and the second substrate are electrically connected is lighter than the weight of the reel when it is operated by an external force when the first substrate and the second substrate are not electrically connected.

[0226] Furthermore, the gaming machines described above, The first substrate is a substrate that receives power from the second substrate. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0227] Furthermore, in the above explanation, A gaming machine equipped with reels (e.g., reels 110-112) that can be operated by motor drive, The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the motor, The state in which the first substrate and the motor are electrically connected is defined as the connected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off. The state in which the connection is made and power is supplied to the gaming machine is defined as the second state. The amount of movement when a predetermined external force is applied to the reel in the first state and it is operated by inertia is different from the amount of movement when the predetermined external force is applied to the reel in the second state and it is operated by inertia. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0228] In this gaming machine, the difference in the amount of movement when the reels rotate by inertia makes it easy to detect abnormalities. Also, if an operator's clothing or tools unintentionally touch the reels, this amount of movement can make it easier to notice the contact. Furthermore, the greater this amount of movement, the more the machine can deflect the force applied to the reels without resisting it, making malfunctions less likely.

[0229] Furthermore, the gaming machines described above, The weight of the reel when it is operated by the predetermined external force in the first state is different from the weight of the reel when it is operated by the predetermined external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0230] Furthermore, the gaming machines described above, In the first state, the weight of the reel when it is operated by the predetermined external force is lighter than the weight of the reel when it is operated by the predetermined external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0231] Furthermore, the gaming machines described above, The amount of operation is greater in the second state than in the first state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0232] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the first state, the weight of the reel when it is operated by the predetermined external force when the first substrate and the second substrate are not electrically connected is lighter than the weight of the reel when it is operated by the predetermined external force when the first substrate and the second substrate are electrically connected. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0233] Furthermore, the gaming machines described above, The first substrate is a substrate that receives power from the second substrate. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0234] Furthermore, in the above explanation, A gaming machine equipped with movable parts that can be operated by the drive of a motor (for example, reels 110-112, movable parts for performance), The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the motor, The state in which the first substrate and the motor are electrically connected is defined as the connected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off.

A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0235] In this gaming machine, the load differs regardless of the direction of movement of the movable parts. Therefore, when an operator moves and checks the movable parts, the direction of movement is not limited to one direction, making the checking process easier. Furthermore, even if an operator's clothing or tools unintentionally touch the movable parts, the light weight and ease of movement of the movable parts allow them to absorb the force without resisting it, thus reducing the likelihood of malfunction.

[0239] Furthermore, in the above explanation, A gaming machine equipped with movable parts that can be operated by the drive of a motor (for example, reels 110-112, movable parts for performance), The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the motor, The state in which the first substrate and the motor are electrically connected is defined as the connected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off.

The sound produced when the movable body is moved by an external force in the first state is different from the sound produced when the movable body is moved by an external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)>, <Regarding the load when the reels are manually rotated with the power on>, and <Regarding the operating noise associated with the load when the reels are manually rotated>) was described.

[0240] This gaming machine makes it easy to detect abnormalities by noticing differences in the sounds produced when the movable parts are moved. Furthermore, if an operator's clothing or tools unintentionally touch a movable part, the sound of the moving part's movement may help detect the contact.

[0241] Furthermore, the gaming machines described above, In the first state, the weight of the movable body when it is moved by an external force is different from the weight of the movable body when it is moved by an external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0242] Furthermore, the gaming machines described above, In the first state, the weight of the movable body when it is moved by an external force is less than the weight of the movable body when it is moved by an external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0243] Furthermore, the gaming machines described above, The operating sound is higher pitched or lower pitched in the second state than in the first state. A gaming machine characterized by the above (see, for example, <Regarding the operating noise associated with the load when the reels are rotated manually>) was described.

[0244] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the first state described above, the weight of the movable body when it is moved by an external force when the first substrate and the second substrate are not electrically connected is lighter than the weight of the movable body when it is moved by an external force when the first substrate and the second substrate are electrically connected. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0245] Furthermore, the gaming machines described above, The first substrate is a substrate that receives power from the second substrate.

The weight of the reel when it is moved in the reverse direction by an external force in the second state is lighter than the weight of the reel when it is moved in the reverse direction by an external force in the first state. In the first state described above, if at least one of the multiple wires of the first harness is disconnected, the weight when the reel is moved by an external force in one direction, either forward or reverse, is different from the weight when the reel is moved by an external force in the same direction if no disconnection occurs in the said wire.

This allows operators to easily check the reels without being limited to a single direction of movement. Furthermore, even if an operator's clothing or tools unintentionally touch the reels, the reels' light weight and ease of rotation allow them to absorb the force without resisting it, thus reducing the likelihood of malfunction.

[0248] Furthermore, the gaming machines described above, In the first state described above, the weight of the reel when it is moved by an external force in one direction, either forward or reverse, when there is no break in the wiring is lighter than the weight of the reel when it is moved by an external force in one direction when there is a break in the wiring. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0249] Furthermore, the gaming machines described above, The state in which the first substrate and the motor are not electrically connected is defined as the disconnected state.

A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0253] In this gaming machine, when an operator moves the reels to check them, if they are functioning correctly, all the reels will move in the same way, making it easier to detect abnormalities by noticing differences in their behavior. Furthermore, even if an operator's clothing or tools unintentionally touch the reels, the light weight and ease of rotation of the multiple reels allow them to absorb the force without resisting it, thus reducing the likelihood of malfunction.

The state in which the connection is made and power is supplied to the gaming machine is defined as the second state. The sound produced when the reel is operated by an external force in the first state is different from the sound produced when the reel is operated by an external force in the second state. In the first state described above, the operating sound when the reel is operated by an external force when at least one of the multiple wires of the first harness is broken is different from the operating sound when the reel is operated by an external force when no break occurs in the said wire. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)>, <Regarding the load when the reels are manually rotated with the power on>, and <Regarding the operating noise associated with the load when the reels are manually rotated>) was described.

[0259] This gaming machine makes it easy to detect abnormalities by noticing differences in the sounds produced when the reels rotate. Furthermore, if an operator's clothing or tools unintentionally touch the reels, the sound of the reels' operation can help detect the contact.

[0260] Furthermore, the gaming machines described above, In the first state described above, the weight of the reel when it is operated by an external force when a break occurs in a certain wire is different from the weight of the reel when it is operated by an external force when a break does not occur in the certain wire. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0261] Furthermore, the gaming machines described above, In the first state described above, the weight of the reel when it is operated by an external force when the wiring is not broken is less than the weight of the reel when it is operated by an external force when the wiring is broken. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0262] Furthermore, the gaming machines described above, The weight of the reel when it is operated by an external force in the first state is different from the weight of the reel when it is operated by an external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0263] Furthermore, the gaming machines described above, The weight of the reel when it is operated by an external force in the second state is lighter than the weight of the reel when it is operated by an external force in the first state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0264] Furthermore, the gaming machines described above, The operating sound is higher pitched or lower pitched in the second state than in the first state. A gaming machine characterized by the above (see, for example, <Regarding the operating noise associated with the load when the reels are rotated manually>) was described.

[0265] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the first state described above, the weight of the reel when it is operated by an external force when the first substrate and the second substrate are electrically connected is lighter than the weight of the reel when it is operated by an external force when the first substrate and the second substrate are not electrically connected. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0266] Furthermore, the gaming machines described above, The first substrate is a substrate that receives power from the second substrate. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0267] Furthermore, in the above explanation, A gaming machine equipped with reels (e.g., reels 110-112) that can be operated by motor drive, The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the motor, The aforementioned gaming machine is equipped with a first harness having multiple wires, The state in which the first circuit board and the motor are electrically connected via the first harness is defined as the connected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off. The state in which the connection is made and power is supplied to the gaming machine is defined as the second state. The amount of movement when a predetermined external force is applied to the reel in the first state and it is operated by inertia is different from the amount of movement when the predetermined external force is applied to the reel in the second state and it is operated by inertia. In the first state described above, if at least one of the multiple wires of the first harness is disconnected, the weight of the reel when it is operated by the predetermined external force is different from the weight of the reel when it is operated by the predetermined external force when the wire is not disconnected. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0268] In this gaming machine, the differences in the amount of movement and weight when the reels rotate by inertia make it easy to detect abnormalities. Also, if an operator's clothing or tools unintentionally touch the reels, this amount of movement can make it easier to notice the contact. Furthermore, the greater this amount of movement, the more the reels can absorb the force rather than resist it, making malfunctions less likely.

[0269] Furthermore, the gaming machines described above, In the first state described above, the weight of the reel when it is operated by the predetermined external force when the wiring is not broken is lighter than the weight of the reel when it is operated by the predetermined external force when the wiring is broken. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0270] Furthermore, the gaming machines described above, The weight of the reel when it is operated by the predetermined external force in the first state is different from the weight of the reel when it is operated by the predetermined external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0271] Furthermore, the gaming machines described above, In the first state, the weight of the reel when it is operated by the predetermined external force is lighter than the weight of the reel when it is operated by the predetermined external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0272] Furthermore, the gaming machines described above, The amount of operation is greater in the second state than in the first state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0273] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the first state, the weight of the reel when it is operated by the predetermined external force when the first substrate and the second substrate are not electrically connected is lighter than the weight of the reel when it is operated by the predetermined external force when the first substrate and the second substrate are electrically connected. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0274] Furthermore, the gaming machines described above, The first substrate is a substrate that receives power from the second substrate. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0275] Furthermore, in the above explanation, A gaming machine equipped with reels (e.g., reels 110-112) that can be operated by motor drive, The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the motor, The aforementioned gaming machine is equipped with a first harness having multiple wires, The state in which the first circuit board and the motor are electrically connected with the connector of the first harness attached is defined as the connected state. The state in which the first circuit board and the motor are not electrically connected because the connector of the first harness is not attached is defined as the disconnected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off. The state in which the connection is made and power is supplied to the gaming machine is defined as the second state. The aforementioned disconnected state and the power supply to the gaming machine being cut off are defined as the third state. In the first state, the weight of the reel when it is operated by an external force is lighter than the weight of the reel when it is operated by an external force in the second state. The weight of the reel when it is operated by an external force in the first state is different from the weight of the reel when it is operated by an external force in the third state. In the first state described above, if at least one of the multiple wires of the first harness is broken, the weight of the reel when it is operated by an external force is different from the weight of the reel when it is operated by an external force when the wire is not broken. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0276] This gaming machine makes it easier to detect abnormalities by observing the difference in load when the reels are operated by external force. Furthermore, even if the worker's clothing or tools unintentionally touch the reels, the reels are lighter and easier to rotate in the first state than in the second state, allowing them to absorb the force without resisting it, thus reducing the likelihood of malfunction.

[0277] Furthermore, the gaming machines described above, The weight of the reel when it is operated by an external force in the third state is lighter than the weight of the reel when it is operated by an external force in the first state. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0278] Furthermore, the gaming machines described above, In the first state described above, the weight of the reel when it is operated by an external force when the wiring is not broken is less than the weight of the reel when it is operated by an external force when the wiring is broken. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0279] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the first state described above, the weight of the reel when it is operated by an external force when the first substrate and the second substrate are electrically connected is lighter than the weight of the reel when it is operated by an external force when the first substrate and the second substrate are not electrically connected. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0280] Furthermore, the gaming machines described above, The first substrate is a substrate that receives power from the second substrate. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0281] Furthermore, in the above explanation, A gaming machine equipped with movable parts that can be operated by the drive of a motor (for example, reels 110-112, movable parts for performance), The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the motor, The aforementioned gaming machine is equipped with a first harness having multiple wires, The state in which the first circuit board and the motor are electrically connected via the first harness is defined as the connected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off. The state in which the connection is made and power is supplied to the gaming machine is defined as the second state. In the first state, the weight of the movable body when it is moved by an external force in the first direction is less than the weight of the movable body when it is moved by an external force in the first direction in the second state. In the first state, the weight of the movable body when it is moved by an external force in a second direction opposite to the first direction is less than the weight of the movable body when it is moved by an external force in the second direction in the second state. In the first state described above, if at least one of the multiple wires of the first harness is disconnected, the weight of the movable body when it is moved by an external force in one direction, either the first or the second direction, is different from the weight of the movable body when it is moved by an external force in the same direction, provided that the wire is not disconnected. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0282] In this gaming machine, the load differs regardless of the direction of movement of the movable parts. Therefore, when an operator moves and checks the movable parts, the direction of movement is not limited to one direction, making the checking process easier. Furthermore, even if an operator's clothing or tools unintentionally touch the movable parts, the light weight and ease of movement of the movable parts allow them to absorb the force without resisting it, thus reducing the likelihood of malfunction.

[0283] Furthermore, the gaming machines described above, In the first state described above, the weight of the movable body when it is moved by an external force in one direction, either the first or second direction, when the wiring is not broken, is less than the weight of the movable body when it is moved by an external force in one direction, either the first or second direction, when the wiring is broken. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0284] Furthermore, the gaming machines described above, The state in which the first substrate and the motor are not electrically connected is defined as the disconnected state. The aforementioned disconnected state and the power supply to the gaming machine being cut off are defined as the third state. In the first state, the weight of the movable body when it is moved by an external force in the first direction is less than the weight of the movable body when it is moved by an external force in the first direction in the third state. In the first state, the weight of the movable body when it is moved by an external force in the second direction is less than the weight of the movable body when it is moved by an external force in the second direction in the third state. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0285] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the first state described above, the weight of the movable body when it is moved by an external force when the first substrate and the second substrate are not electrically connected is lighter than the weight of the movable body when it is moved by an external force when the first substrate and the second substrate are electrically connected. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0286] Furthermore, the gaming machines described above, The first substrate is a substrate that receives power from the second substrate. A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0287] Furthermore, in the above explanation, A gaming machine equipped with movable parts that can be operated by the drive of a motor (for example, reels 110-112, movable parts for performance), The gaming machine includes a first circuit board (for example, a main control board 300B in Figure 13, see <Circuit Board Configuration (1)> and <Circuit Board Configuration (2)>) that can be electrically connected to the motor, The aforementioned gaming machine is equipped with a first harness having multiple wires, The state in which the first circuit board and the motor are electrically connected via the first harness is defined as the connected state. The first state is defined as the connection state and the power outage state in which the power supply to the gaming machine is cut off. The state in which the connection is made and power is supplied to the gaming machine is defined as the second state. The sound produced when the movable body is moved by an external force in the first state is different from the sound produced when the movable body is moved by an external force in the second state. In the first state described above, if at least one of the multiple wires of the first harness is disconnected, the operating sound when the movable body is moved by an external force is different from the operating sound when the movable body is moved by an external force when the wire is not disconnected. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)>, <Regarding the load when the reels are manually rotated with the power on>, and <Regarding the operating noise associated with the load when the reels are manually rotated>) was described.

[0288] This gaming machine makes it easy to detect abnormalities by noticing differences in the sounds produced when the movable parts are moved. Furthermore, if an operator's clothing or tools unintentionally touch a movable part, the sound of the moving part's movement may help detect the contact.

[0289] Furthermore, the gaming machines described above, In the first state described above, the weight of the movable body when it is moved by an external force when a break occurs in a certain wire is different from the weight of the movable body when it is moved by an external force when a break does not occur in the certain wire. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0290] Furthermore, the gaming machines described above, In the first state described above, the weight of the movable body when it is moved by an external force when the wiring is not broken is less than the weight of the movable body when it is moved by an external force when the wiring is broken. A gaming machine characterized by the above (see, for example, <Operation when the reels are manually rotated with the power off (1)>) was described.

[0291] Furthermore, the gaming machines described above, In the first state, the weight of the movable body when it is moved by an external force is different from the weight of the movable body when it is moved by an external force in the second state. A gaming machine characterized by the above (see, for example, <Regarding operation when the reels are manually rotated with the power off (1)> and <Regarding the load when the reels are manually rotated with the power on>) was described.

[0292] Furthermore, the gaming machines described above, In the first state, the weight of the movable body when it is moved by an external force is less than the weight of the movable body when it is moved by an external force in the second state.

[0293] Furthermore, the gaming machines described above, The operating sound is higher pitched or lower pitched in the second state than in the first state. A gaming machine characterized by the above (see, for example, <Regarding the operating noise associated with the load when the reels are rotated manually>) was described.

[0294] Furthermore, the gaming machines described above, The gaming machine further comprises a second circuit board that can be electrically connected to the first circuit board, In the first state described above, the weight of the movable body when it is moved by an external force when the first substrate and the second substrate are not electrically connected is lighter than the weight of the movable body when it is moved by an external force when the first substrate and the second substrate are electrically connected.

A gaming machine characterized by the above (see, for example, <Regarding the configuration of the circuit board (1)> and <Regarding the configuration of the circuit board (2)>) has been described.

[0296] The following describes an embodiment of the gaming machine (slot machine) using Figures 27 to 47. Note that in cases where terms overlap with other embodiments, the terms in this embodiment take precedence. Similarly, in cases where descriptions overlap with drawings other than Figures 27 to 47, the descriptions in Figures 27 to 47 take precedence.

[0297] The slot machines described below employ a so-called "coinless" configuration, using information equivalent to the actual number of tokens (virtual token count). However, in the following explanation, this information will be referred to as "token count."

[0298] [First Embodiment] The slot machine of this embodiment is a gaming machine that proceeds through a series of games in which a predetermined number of game tokens are inserted, and multiple reels, each decorated with multiple types of symbols, start to rotate when a predetermined rotation start instruction operation is received, and based on the receipt of the rotation start instruction operation, the success or failure of an internal win of one of multiple types of winning combinations is determined by lottery, each of the multiple reels stops rotating individually when a predetermined rotation stop instruction operation is received, and if the conditions determined by the winning combination based on the result of the lottery and the combination of symbols when the multiple reels stop match predetermined payout conditions, a process of paying out the number of game tokens is executed and the game ends, and if the conditions do not match, the process of paying out the number of game tokens is not executed and the game ends.

[0299] Traditionally, some gaming machines have displayed the number of coins won during advantageous gameplay states such as AT (Automatic Trigger) or bonus rounds, aiming to give players a sense of satisfaction. However, this sense of satisfaction can only be felt when a certain number of coins are won (for example, 500 or 1000 coins). Conversely, when the number of coins won is small (for example, 50 or 100 coins), displaying the number of coins won may not only fail to satisfy players but could even cause dissatisfaction, potentially irritating them.

[0300] Furthermore, previously, if a minimum number of bets was set that would prevent gameplay (a minimum number of bets below the specified limit), the demo screen was not displayed. As a result, game machines that ended with a minimum number of bets set that would prevent gameplay were not recognized as vacant and were left vacant for extended periods.

[0301] This embodiment provides a gaming machine that can solve the above-mentioned problems.

[0302] <Overall Structure> First, Figure 27 will be used to explain the basic configuration of the slot machine 100 and the dispensing machine 700. Figure 27 is an external perspective view of the slot machine 100 and the dispensing machine 700 as seen from the front (player side).

[0303] The slot machine 100 shown in Figure 27 is an example of a gaming machine according to the present invention, and comprises a main body 101 and a front door 102 attached to the front side of the main body 101 and which can be opened and closed relative to the main body 101. Inside the center of the main body 101 (not shown), there are three reels (left reel 110, middle reel 111, right reel 112) with multiple types of symbols arranged on their outer surfaces, and are configured to rotate inside the slot machine 100. These reels 110 to 112 are driven to rotate by a drive device such as a stepping motor.

[0304] In this embodiment, each design is printed at equal intervals in appropriate numbers on a strip-shaped member, and this strip-shaped member is attached to a predetermined circular cylindrical frame to constitute each reel 110 to 112. From the player's perspective, approximately three designs are displayed vertically through the display window 113 on the reels 110 to 112, so that a total of nine designs are visible. The symbols displayed on the upper part of the left reel 110 are called the left reel upper symbols, the symbols displayed on the middle part of the left reel 110 are called the left reel middle symbols, the symbols displayed on the lower part of the left reel 110 are called the left reel lower symbols, the symbols displayed on the upper part of the middle reel 111 are called the middle reel upper symbols, the symbols displayed on the middle part of the left reel 111 are called the middle reel middle symbols, the symbols displayed on the lower part of the middle reel 111 are called the middle reel lower symbols, the symbols displayed on the upper part of the right reel 112 are called the right reel upper symbols, the symbols displayed on the middle part of the right reel 112 are called the right reel middle symbols, and the symbols displayed on the lower part of the right reel 112 are called the right reel lower symbols. Each symbol for each reel 110 to 112 is displayed three times vertically on each reel from 110 to 112 through the display window 113, for a total of nine symbols. By rotating each of the reels 110-112, the combination of symbols visible to the player changes. In other words, each of the reels 110-112 functions as a display device that can display multiple combinations of symbols in a variable manner. In addition to reels, other electronic image display devices such as liquid crystal displays can also be used as such display devices. Furthermore, although the slot machine 100 shown in Figure 27 has three reels located inside the center of the slot machine 100, the number of reels and their placement are not limited to this.

[0305] A backlight (not shown) is positioned on the back of each reel 110-112 to illuminate the individual symbols displayed in the display window 113. It is desirable that the backlight be shielded for each symbol so that each symbol is illuminated evenly. Inside the slot machine 100, an optical sensor (not shown) consisting of a light-emitting part and a light-receiving part is provided near each reel 110-112, and a light-shielding piece of a certain length provided on the reel passes between the light-emitting and light-receiving parts of this optical sensor. Based on the detection results of this optical sensor, the rotational position of the symbols on the reels is determined, and the reels 110-112 are stopped so that the target symbol is displayed on the winning line.

[0306] The winning line indicator lamp 120 is a lamp that indicates the valid winning lines. A winning line is a line on which it is determined whether or not a combination of symbols corresponding to a winning combination has been displayed. The valid winning lines are predetermined by the number of medals bet as the game medium. There are five winning lines. For example, if one medal is bet, the middle horizontal winning line becomes valid. If two medals are bet, the upper horizontal winning line and the lower horizontal winning line are added, making a total of three lines valid. If three medals are bet, the lower right downward winning line and the upper right upward winning line are added, making a total of five lines valid as winning lines. Note that the number of winning lines is not limited to five lines. For example, if one medal is bet, the middle horizontal winning line, the upper horizontal winning line, the lower horizontal winning line, the lower right downward winning line, and the upper right upward winning line may all be considered valid winning lines. Hereafter, the valid winning lines may be referred to as "valid lines."

[0307] The notification lamp 123 is a lamp that informs the player that, for example, they have internally won a specific winning combination (e.g., a bonus combination, a special combination) in the internal lottery described later, or that this internally won state has been carried over. The coin insertion lamp 124 is a lamp that informs the player that they can insert coins. The replay lamp 122 is a lamp that informs the player that they can replay the game (no coin insertion is required) if they won a replay combination, which is one of the winning combinations, in the previous game. The reel panel lamp 128 is a lamp for visual effects.

[0308] The bet buttons 130 or 132 are buttons for inserting a predetermined number of tokens (called credits) electronically stored in the slot machine 100. In the slot machine 100 shown in Figure 27, one token is inserted each time the bet button 130 is pressed. One token is inserted when pressed once, an additional token is inserted when pressed again (total of 2 tokens), and an additional token is inserted when pressed again (total of 3 tokens). When the bet button 132 is pressed, 3 tokens are inserted. Hereinafter, the bet button 130 may be referred to as the 1-token bet button, and the bet button 132 may be referred to as the MAX bet button. The game token insertion lamp 129 lights up a number of lamps corresponding to the number of tokens inserted, and when the prescribed number of tokens has been inserted, the game start lamp 121 lights up to indicate that the game can be started. In this embodiment, the slot machine 100 is a game machine exclusively for 3-token bets, so the prescribed number of tokens is 3.

[0309] The game information display unit 126 is a display unit for displaying various internal information (for example, the number of medals dispensed during bonus gameplay) numerically. The payout display unit 127 is a display unit for displaying the number of medals dispensed to the player as a result of winning a prize. In the following, the expression "dispensed to the player" may be used interchangeably with "given to the player." The game information display unit 126 and the payout display unit 127 are composed of 7-segment (SEG) displays.

[0310] The start lever 135 is a lever-type switch used to initiate the rotation of reels 110-112. That is, by operating the bet button 130 or 132 and then operating the start lever 135, reels 110-112 will begin to rotate. The operation of the start lever 135 is referred to as the game start operation.

[0311] The stop button unit 136 is equipped with stop buttons 137-139, consisting of a left stop button 137, a middle stop button 138, and a right stop button 139. The stop buttons 137-139 are button-type switches for individually stopping the reels 110-112 that have started rotating by the operation of the start lever 135, and each is associated with a specific reel 110-112. More specifically, the left reel 110 can be stopped by operating the left stop button 137, the middle reel 111 can be stopped by operating the middle stop button 138, and the right reel 112 can be stopped by operating the right stop button 139. Hereinafter, operations on the stop buttons 137-139 will be referred to as stop operations, with the first stop operation being the first stop operation, the next stop operation being the second stop operation, and the last stop operation being the third stop operation. The reels that are stopped in response to these stop operations will be referred to as the first stop reel, the second stop reel, and the third stop reel, respectively. Furthermore, the order in which the stop buttons 137-139 are pressed to stop all of the rotating reels 110-112 is called the operation order or pressing order. Moreover, the operation order in which the first stop operation is the left reel 110, the second stop operation is the middle reel 111, and the third stop operation is the right reel 112 is called the "forward pressing order" or simply "forward pressing," and the operation order in which the first stop operation is the right reel 112, the second stop operation is the middle reel 111, and the third stop operation is the left reel 110 is called the "reverse pressing order" or simply "reverse pressing." In addition, a light-emitting element may be provided inside each of the stop buttons 137-139, and if the stop buttons 137-139 can be operated, the light-emitting element can be illuminated to inform the player.

[0312] The instruction monitor 125 is a display unit that shows information regarding the operation order (pressing order) of the stop buttons 137 to 139. This instruction monitor 125 is also composed of a 7-segment (SEG) display unit. For example, if the instruction is to operate the left stop button 137, the middle stop button 138, and the right stop button 139 in that order, "1" will be displayed on the instruction monitor 125. If the instruction is to operate the left stop button 137, the right stop button 139, and the middle stop button 138 in that order, "2" will be displayed on the instruction monitor 125.

[0313] The settlement button 134 is a button for returning the inserted game tokens (number of tokens wagered) to the token count control unit 350. The door keyhole 140 is a hole for inserting a key to unlock the front door 102 of the slot machine 100.

[0314] The game token count display device 170 is a 5-digit 7-segment (SEG) display that displays the number of game tokens recorded by the token count control unit 350 shown in Figure 28.

[0315] The counting button 171 is an operating means for transmitting information about the number of game tokens recorded in the token count control unit 350 shown in Figure 28 to the dispensing machine 700.

[0316] A title panel 162 is provided at the bottom of the stop button unit 136 for displaying the model name and for attaching various certification labels.

[0317] The sound hole 145 is a hole for outputting sound from the speaker 277 (see Figure 28) located inside the slot machine 100 to the outside. The side lamps 144 located on the left and right sides of the front door 102 are decorative lamps to enhance the gaming experience. A performance device 160 is located above the front door 102, and a sound hole 143 for outputting sound from the speaker 272 (see Figure 28) to the outside is provided above the performance device 160. This display device 160 includes a shutter (shielding device) 163 consisting of two horizontally opening and closing shutters, a right shutter 163a and a left shutter 163b, and a display image display device 157 (liquid crystal display device) positioned behind the shutter 163. When the right shutter 163a and the left shutter 163b are opened horizontally outward in front of the display image display device 157, the display screen of the display image display device 157 appears on the front (player side, front side) of the slot machine 100. Note that any display device capable of displaying various display images and various game information is acceptable, rather than a liquid crystal display device. For example, a multi-segment display (7-segment display), a dot matrix display, an organic EL display, a plasma display, a reel (drum), or a display device consisting of a projector and a screen may be used. The display screen is rectangular and configured so that the entire screen is visible to the player. In this embodiment, the display screen is rectangular, but it may also be square. Furthermore, decorative elements (not shown) can be placed around the periphery of the display screen, so that a portion of the periphery of the display screen is hidden by these elements, resulting in the display screen appearing to have an irregular shape. In this embodiment, the display screen is a flat surface, but it may also be a curved surface. Note that this presentation image display device 157 is an example of a presentation means.

[0318] The dispensing machine 700 shown in Figure 27 may also be called a card unit and is an example of the gaming media management device of the present invention. This dispensing machine 700 is installed in a one-to-one relationship with the slot machine 100.

[0319] The rental machine 700 accepts cards. There are two types of "cards" referred to here. One is a visitor card (also called a general card), a prepaid gaming memory medium issued to general players who are not registered members. The other is a membership card, a gaming memory medium issued to registered players who have registered with the arcade. IC cards are used for both types of cards.

[0320] The cards store monetary value. This monetary value includes the "number of medals held" and the "money balance," which is the remaining balance of prepaid money.

[0321] The card-receiving machine 700 has a function to convert the "number of tokens held" stored on the card into "number of game tokens (credits)". The "number of game tokens (credits)" is data that can be used to set the number of bets and can also be converted into the "number of tokens held". The "number of game tokens" is obtained by deducting the "money balance" or "number of tokens held" from the card. The "number of game tokens" also includes the number of tokens won through winning. This "number of game tokens" is managed by the token count control unit 350 shown in Figure 28 and is the number of electronic tokens (amount of electronic game value) stored electromagnetically. The "number of game tokens" is decreased by performing the insertion operation using the bet buttons 130 and 132.

[0322] "Number of tokens held" is the value obtained by counting the "number of game tokens (number of credits)". This "number of tokens held" is stored in a identifiable way on the player's card. In other words, by operating the counting button 171, the "number of game tokens" can be converted to "number of tokens held" and stored on the card. Alternatively, the "number of tokens held" may be managed by a token count management device installed in the arcade.

[0323] The front of the lending machine 700 is provided with a banknote slot 701 at the top for inserting banknotes and a card slot 702 at the bottom for inserting cards. Member cards and visitor cards inserted into the card slot 702 are received by a card reader / writer, and the information stored on the card is read. Banknotes inserted into the banknote slot 701 are identified for authenticity and type, and the face value of the banknotes is stored as the "money balance" on the card inserted into the card slot 702.

[0324] Below the banknote slot 701, an information display 703 is provided. This information display 703 is a display that provides information such as operating instructions for the lending machine 700 and the status of the slot machine 100 in text and images. Alternatively, the surface may be configured as a touch panel, allowing various operations to be input by touching the displayed items with a finger.

[0325] Below the information display 703, the cash balance display 705 and the medal balance display 706 are arranged in two rows, one above the other. The cash balance display 705 displays the "cash balance" stored on the card inserted into the card slot 702 as an amount. On the other hand, the medal balance display 706 displays the "number of medals held" stored on the card inserted into the card slot 702 as the number of medals.

[0326] The central part of the dispensing machine 700 is provided with a dispensing button 707 and a card return button 708. The dispensing button 707 is an operating means for withdrawing the "money balance" stored in the card inserted into the card slot 702 and obtaining the "number of game tokens". Specifically, if there is a "money balance" on the card inserted into the card slot 702, the LED lamp built into the dispensing button 707 lights up to indicate that it is ready to withdraw. By operating the dispensing button 707 in this state, the "number of game tokens" will be added according to the amount of money to be withdrawn. For example, the "number of game tokens" equivalent to 1000 yen will be added as a predetermined amount. Also, if the "money balance" on the card is less than a predetermined amount (for example, less than 1000 yen), only the "number of game tokens" converted from the current balance at a predetermined rate will be added. Furthermore, even if the card's "money balance" is less than a predetermined amount, it may be replenished from the "number of tokens held" stored on the card, so that the predetermined amount of "game tokens" is added. The card return button 708 is operated when the player finishes playing, and is a means of operation to store the "number of tokens held" determined at the end of the game on the card inserted in the card slot 702 and eject it. The "number of tokens held" determined at the end of the game is the number of tokens obtained by subtracting the number of tokens converted to "game tokens" from the "number of tokens held" stored on the card inserted in the card slot 702, and then adding the number of game tokens counted by the counting operation. The "money balance," "number of tokens held," and "number of game tokens" data described above are converted in the following order: "money balance" and "number of tokens held" → "game tokens" → "number of tokens held." In this way, the "number of tokens held" identified by the card is converted into the "number of game tokens," and in the slot machine 100 of this embodiment, the number of tokens can be used to set the bet. Therefore, it is possible to provide a new type of slot machine (managed gaming machine) that does not use physical tokens, without confusing players who are accustomed to conventional slot machines where players receive physical tokens, insert those physical tokens to secure credits, and then use those credits to set the bet.

[0327] Although this specification does not mention "stored medals," this "stored medals" refers to the number of medals deposited with the arcade, not stored on the card. The arcade may manage the number of medals a player has acquired through gameplay as "points" for the day, and as "stored medals" from the following day onward, using a hall management terminal or other management computer. If both "stored medals" and "held medals" are stored, the "held medals" will be deducted first. Both "held medals" and "stored medals" may also be stored in a higher-level server (not shown) in association with the card number. In the case of visitor cards, the "held medals" are stored directly on the visitor card, but the "held medals" may also be stored in a higher-level server in association with the card number. When storing the information in the higher-level server in association with the card number, data that identifies the time the information was stored in the higher-level server may be written to the card (member card, visitor card) before it is dispensed. Furthermore, the "money balance" is written directly to the card (member card, visitor card) and dispensed. The timing for storing the "number of tokens held" on the card (member card, visitor card) or on the higher-level server is, for example, when the counting button 171 is operated and the counting process is performed. However, instead, the information may be stored all at once when the card is returned. Moreover, when a player finishes playing and returns the card from the dispensing machine 700, the "number of tokens held" that was stored in the dispensing machine 700 may be temporarily stored as stored tokens in the hall management terminal 800. When that player inserts the card into the same or a different dispensing machine 700 again on the same day the card was returned, only the "number of tokens held" for that day, which was temporarily stored as stored tokens, will be stored again in the dispensing machine 700, and the "number of tokens to play" will be added within the range of that "number of tokens held" so that the player can play.

[0328] Furthermore, the rental machine 700 may be equipped with an IR photosensitive unit that receives infrared signals from a remote control held by an employee of the gaming hall, converts them into electronic signals, and outputs them.

[0329] Furthermore, in the lending machine 700 shown in Figure 27, lending "game tokens" was possible by operating the lending button 707 to withdraw the "money balance" stored on the card. However, it may also be possible to withdraw the "number of tokens held" recorded on the card and convert it into "game tokens." Specifically, the lending machine 700 is provided with a "number of tokens held" button, and if there are "number of tokens held" on the card inserted in the card slot 702, the LED lamp built into the "number of tokens held" button lights up in a manner that indicates that it is ready to withdraw. In this state, by operating the "number of tokens held" button, if there are a predetermined number of tokens (for example, 50 tokens) or more, the predetermined number (for example, 50 tokens) of "game tokens" will be added. In addition, the number of tokens held by the player during gameplay, as described above, is stored on the card as "points held" for the rest of the day, or managed by the hall management terminal 800 or other management computer, and the lending machine 700 is provided with a replay button. If there are "points remaining," the built-in LED lamp on the replay button lights up in a manner that indicates it is ready to be played. In this state, operating the replay button may add a predetermined number of "game tokens" (for example, 50 tokens).

[0330] <Control Unit Circuit Configuration> Next, the circuit configuration of the control unit of the slot machine 100 will be explained in detail using Figure 28. Note that this figure shows a circuit block diagram of the control unit.

[0331] The control unit of the slot machine 100 is broadly composed of a main control unit 300 that controls the progress of the game, a first sub-control unit 400 that controls the main effects in accordance with command signals (hereinafter simply referred to as "commands") transmitted by the main control unit 300, and a second sub-control unit 500 that controls various devices based on commands transmitted from the first sub-control unit 400. Here, regarding the main control unit 300, since a large data capacity would make it difficult to verify the program and could also lead to security problems such as becoming a breeding ground for illegal modifications, the data capacity of the ROM 306 and RAM 308 of the main control unit 300 is limited.

[0332] <Main Control Unit> First, the main control unit 300 of the slot machine 100 will be described. The main control unit 300 has a game control unit 302 that controls the progress of the game and a medal count control unit 350 that controls the number of game medals owned by the player. The game control unit 302 is an example of a game control means, and the medal count control unit 350 is an example of a game value control means. The game control unit 302 is equipped with a CPU 304, a ROM 306 that stores control program data, lottery data used when internally drawing winning combinations, the arrangement of reel symbols and stopping positions, etc., a RAM 308 for temporarily storing data, an I / O 310 for controlling the input and output of various devices, a counter timer 312 for measuring time, number of times, etc., and a WDT (watchdog timer) which is not shown. Note that other storage devices may be used instead of ROM 306 and RAM 308, and the same applies to the medal count control unit 350, the first sub-control unit 400, and the second sub-control unit 500 which will be described later. The CPU 304 of the game control unit 302 operates by inputting a clock signal of a predetermined period output by a crystal oscillator (not shown) as the system clock. Furthermore, when the power is turned on, the CPU 304 sends frequency division data stored in a predetermined area of ​​the ROM 306 to the counter timer 312. The counter timer 312 determines the interrupt time based on the received frequency division data and sends an interrupt request to the CPU 304 at each interrupt time. The CPU 304 then performs monitoring of various sensors and transmission of drive pulses based on this interrupt request. For example, if the clock signal output by the crystal oscillator 315b is set to 8MHz, the frequency division value of the counter timer 312 is set to 1 / 256, and the frequency division data in the ROM 306 is set to 47, the reference interrupt time will be 256 × 47 ÷ 8MHz = 1.504ms.

[0333] The main control unit 300 includes a random number generation circuit (not shown) used as a hardware random number counter that varies a value in the range of 0 to 65535 based on a clock signal input from a crystal oscillator (not shown), and a startup signal output circuit (not shown) that outputs a startup signal (reset signal) when the power is turned on. The CPU 304 of the game control unit 302 starts game control when it receives a startup signal from this startup signal output circuit.

[0334] Furthermore, the CPU 304 of the game control unit 302 monitors the status of each bet button 130, 132, start lever 135, each stop button 137-139, and payout button 134 at each interrupt time. For example, if it detects that the bet buttons 130 or 132 have been turned on, the medal count control unit 350 executes a process to electronically insert the medals electronically stored in the medal count control unit 350 as medals to be inserted into the game. If it detects that the start lever 135 has been turned on, it outputs a signal indicating this detection to the random number generation circuit. The random number generation circuit that receives this signal latches the value at that timing and stores it in a register that stores random values ​​to be used for the lottery. If it detects that the left stop button 137, middle stop button 138, or right stop button 139 has been turned on, and the reels 110-112 corresponding to each stop button are in a stopable state, it executes stop control for the reels 110-112. If it is detected that the settlement button 134 has been turned on, the system will execute a process to return the electronically inserted game tokens to the token count control unit 350.

[0335] Furthermore, the CPU 304 of the game control unit 302 also monitors the status of various sensors 318 (optical sensor for the left reel 110, optical sensor for the middle reel 111, optical sensor for the right reel 112, etc.) at each interrupt time. The optical sensors for the left reel 110, the middle reel 111, and the right reel 112 are installed at predetermined positions on the mounting bases of each reel 110-112, and each time a light-shielding piece provided on the reel frame passes over them, they reach an L level. The rotation position information, which indicates how much the reel has rotated from the reference position between the time it reaches an L level and the next time it reaches an L level, is calculated based on the value obtained by counting the clock signal output by the crystal oscillator 315b. When the CPU 304 detects the above L level signal, it determines that the reel has rotated once and resets the rotation position information of the reel to zero. This rotation position information is stored in the RAM 308 of the main control unit 300.

[0336] The main control unit 300 includes a drive circuit 322 that drives the motors provided on the reels 110 to 112, a drive circuit 324 that drives display devices such as the instruction monitor 125, the game information display 126, and the payout count display 127, and a drive circuit 326 that drives various lamps 336 (winning line indicator lamp 120, notification lamp 123, game token insertion ready lamp 124, replay lamp 122, game token insertion lamp 129, game start lamp 121).

[0337] Furthermore, slot machine 100 has different setting values ​​that affect the player's advantage. There are six setting values ​​available, from setting 1 to setting 6. Generally, the higher the setting value, the greater the player's advantage. Specifically, an internal winning probability is determined for each setting value. Even if the internal winning probability is the same for each setting value, there may be differences in the settings for AT-related lotteries such as AT transition lotteries and AT bonus lotteries, and for CZ-related lotteries such as CZ transition lotteries and high-probability transition lotteries that make CZ transitions more favorable. A setting change button 175 is connected to the game control unit 302, which is operated when changing these setting values.

[0338] Furthermore, an information output circuit 328 is connected to the game control unit 302, and the main control unit 300 outputs game information of the slot machine 100 (for example, information indicating the state of the game) to an information input circuit 650 provided by an external hall computer (not shown) via this information output circuit 328.

[0339] Furthermore, the main control unit 300 is equipped with a voltage monitoring circuit (not shown) that monitors the voltage value of the power supply supplied to the main control unit 300 from the power management unit (not shown). This voltage monitoring circuit outputs a low voltage signal to the game control unit 302 and the medal count control unit 350, respectively, when the voltage value of the power supply falls below a predetermined value (for example, 9V), indicating that the voltage has dropped.

[0340] Furthermore, the main control unit 300 is equipped with an output interface for sending commands to the first sub-control unit 400, enabling communication with the first sub-control unit 400. Information communication between the main control unit 300 and the first sub-control unit 400 is unidirectional; the main control unit 300 is configured to send signals such as commands to the first sub-control unit 400, but the first sub-control unit 400 is configured not to send signals such as commands to the main control unit 300.

[0341] The medal count control unit 350, like the game control unit 302, is equipped with a CPU 354, ROM 356, RAM 358, I / O 360 for controlling the input / output of various devices, and a counter timer 362 for measuring time, counts, etc. The CPUs 304 and 354 are mounted on the same board and connected via a buffer IC. This allows the CPU 304 to use ROM 306 and RAM 308 without using ROM 356 and RAM 358, and vice versa. A WDT (watchdog timer), not shown in the diagram, is also included. The CPU 354 of the medal count control unit 350 also operates by receiving a clock signal of a predetermined period output by a crystal oscillator (not shown) as the system clock. Furthermore, when power is turned on, the CPU 354 transmits frequency division data stored in a predetermined area of ​​the ROM 356 to the counter timer 362. The counter timer 362 determines the interrupt time based on the received frequency division data and sends an interrupt request to the CPU 354 at each interrupt time. The CPU 354 operates in response to this interrupt request. This medal count control unit 350 executes the interrupt processing every 0.745ms. It also communicates with the dispensing machine 700 every 300ms.

[0342] The CPU 354 of the medal count control unit 350 is also equipped with a startup signal output circuit (not shown) that outputs a startup signal (reset signal) when the power is turned on, and the CPU 354 of the medal count control unit 350 also starts medal count control when a startup signal is input from this startup signal output circuit.

[0343] The basic circuit of the medal count control unit 350 is connected to a game medal count display device 170 consisting of a 5-digit 7-segment (SEG) display, a counting button 171, and a game medal count clear button 172.

[0344] Furthermore, the basic circuit of the medal count control unit 350 is also connected to the lending machine 700 via the lending machine connection terminal board 790. The medal count control unit 350 communicates bidirectionally with the lending machine 700.

[0345] The medal count control unit 350 sends various commands to the game control unit 302. The game control unit 302 also sends various commands to the medal count control unit 350. In other words, communication between the medal count control unit 350 and the game control unit 302 is bidirectional.

[0346] Furthermore, the medal count control unit 350 stores the "number of game medals" in a predetermined area of ​​the RAM 358. Specifically, the "number of game medals" is stored in the credit counter. The medal count control unit 350 updates the "number of game medals" stored in the predetermined area of ​​the RAM 358 by addition or subtraction processing. Addition processing includes processing based on payout commands transmitted from the game control unit 302, processing based on settlement commands transmitted from the game control unit 302, and processing based on loan notifications transmitted from the loan machine 700. On the other hand, subtraction processing includes counting processing based on the operation of the counting button 171, and processing based on insert commands transmitted from the game control unit 302.

[0347] The game token count clear button 172 shown in Figure 28 is located in a position that players cannot operate (for example, a position that cannot be operated without opening the front door 102), and is a means of clearing the "game token count" stored in a predetermined area of ​​the RAM 358. For example, if the game token count remains at "2" and the player is absent, it becomes difficult to determine whether the player who left "2" intends to continue playing or not, and another player may not be able to start playing. However, if the game token count can be cleared by an employee, another player can be welcomed sooner. Note that the game token count clear button 172 does not necessarily clear the "game token count" when it is operated. For example, it may be set to clear only when the game token count is 2 or less, and if there are 3 or more, the tokens may be counted in the same way as when the counting button 171 is operated. If the counting button 171 malfunctions and the system cannot recognize that it has been operated, it may become impossible to convert the "number of game tokens played" to the "number of tokens held," potentially causing disadvantage to the player. However, if counting is also possible through operation by a store employee, this disadvantage to the player can be avoided. Furthermore, there is no need to install a new counting button for employees, thus avoiding increased costs. In addition, instead of determining the number of game tokens to decide whether to clear or count, the clearing and counting actions could be determined by how the game token count clear button 172 is operated. For example, a short press could clear the tokens, and a long press could count them. This would allow for easy selection of either clearing or counting, regardless of the number of game tokens. Alternatively, if only the game token count clear button 172 is operated, the tokens would be cleared, and if the game token count clear button 172 and another button are operated simultaneously, the tokens would be counted. This would reduce the possibility of operational errors and allow for easy selection of either clearing or counting.

[0348] <Deputy Commander> Next, the first sub-control unit 400 of the slot machine 100 will be described. The first sub-control unit 400 receives control commands transmitted by the main control unit 300 (game control unit 302) via an input interface. The first sub-control unit 400 is equipped with a basic circuit 402 that controls the entire first sub-control unit 400 based on these control commands. This basic circuit 402 is equipped with a CPU 404, a RAM 408 for temporarily storing data, an I / O 410 for controlling the input and output of various devices, and a counter timer 412 for measuring time, number of times, etc. The CPU 404 of the basic circuit 402 operates by receiving a clock signal of a predetermined period output by a crystal oscillator 414 as the system clock. The ROM 406 stores control programs and data for controlling the entire first sub-control unit 400, data for controlling the backlight lighting patterns and various indicators, etc.

[0349] The CPU 404 transmits frequency division data stored in a predetermined area of ​​the ROM 406 to the counter timer 412 via the data bus at a predetermined timing. The counter timer 412 determines the interrupt time based on the received frequency division data and sends an interrupt request to the CPU 404 at each interrupt time. The CPU 404 controls each IC and circuit based on the timing of this interrupt request.

[0350] Furthermore, the first sub-control unit 400 is equipped with an audio amplifier IC 418, and speakers 272 and 277 are connected to the audio amplifier IC 418 via an output interface. The audio amplifier IC 418 controls the sound output from the amplifier and speakers 272 and 277 in response to commands from the CPU 404. An S-ROM (sound ROM) containing audio data is connected to the audio amplifier IC 418, and the audio data acquired from this ROM is amplified by the amplifier and output from speakers 272 and 277. These speakers 272 and 277 are examples of performance elements.

[0351] Furthermore, the first sub-control unit 400 is equipped with a drive circuit 422, to which various lamps 420 (upper lamp, lower lamp, side lamp 144, title panel lamp, bet button lamp, reel backlight, etc.) are connected via an input / output interface. The various lamps 420 are examples of the effects and effects.

[0352] Furthermore, the first sub-control unit 400 is equipped with a drive circuit 424 that drives the motor of the shutter 163, and the shutter 163 is connected to the drive circuit 424 via an output interface. This drive circuit 424 outputs a drive signal to a stepping motor (not shown) provided on the shutter 163 in response to a command from the CPU 404.

[0353] Furthermore, the first sub-control unit 400 is equipped with a sensor circuit 426, to which a shutter sensor 428 is connected via an input interface. The CPU 404 monitors the status of the shutter sensor 428 at interrupt intervals.

[0354] Furthermore, the CPU 404 transmits and receives signals to the second sub-control unit 500 via an output interface. The second sub-control unit 500 performs various controls of the performance device 160, including the display control of the performance image display device 157. The second sub-control unit 500 may be composed of multiple control units, such as a control unit that controls the display of the performance image display device 157 and a control unit that controls various performance drive devices (for example, a control unit that controls the motor drive of the shutter 163).

[0355] The second sub-control unit 500 receives control commands transmitted by the first sub-control unit 400 via an input interface and includes a basic circuit 502 that controls the entire second sub-control unit 500 based on these control commands. This basic circuit 502 is equipped with a CPU 504, a RAM 508 for temporarily storing data, an I / O 510 for controlling the input and output of various devices, and a counter timer 512 for measuring time, counts, etc. The CPU 504 of the basic circuit 502 operates by receiving a clock signal of a predetermined period output by a crystal oscillator 514 as the system clock. The ROM 506 stores control programs and data for controlling the entire second sub-control unit 500, as well as data for image display, etc.

[0356] The CPU 504 transmits frequency division data stored in a predetermined area of ​​the ROM 506 to the counter timer 512 via the data bus at a predetermined timing. The counter timer 512 determines the interrupt time based on the received frequency division data and sends an interrupt request to the CPU 404 at each interrupt time. The CPU 504 controls each IC and circuit based on the timing of this interrupt request.

[0357] Furthermore, the second sub-control unit 500 is equipped with a VDP 516 (video display processor), to which a ROM 506 and a VRAM 518 are connected via a bus. Based on signals from the CPU 504, the VDP 516 reads image data stored in the ROM 506, generates a display image using the work area of ​​the VRAM 518, and displays the image on the image display device 157.

[0358] <Demo screen transition> Next, the demo screen transitions according to this embodiment will be explained using Figures 29 and 30. As mentioned above, the slot machine 100 is a machine exclusively for betting 3 coins.

[0359] In this embodiment, the demo screen is started when (A) the number of medals acquired on the day (MY) reaches a predetermined number L, and (1) a waiting time M has elapsed since all reels stopped, (2) a waiting time M has elapsed since medals were inserted when the number of bets (number of tokens wagered) is not the predetermined number, i.e., when the number of tokens wagered is 1 or 2, or (3) a waiting time M has elapsed since some operation was performed on the gaming machine.

[0360] Here, "any operation on the gaming machine" refers to operations on the counting button 171 or the payout button 143, or operations on the buttons for calling up the player menu screen or adjusting the volume and brightness of the effects. These operations are accepted during the period before the game starts (non-game period), and the demo screen starts when the waiting time M has elapsed since the last operation was performed. In this embodiment, the predetermined number of coins L is set to 1000 coins and the waiting time M is set to 1 minute, but it is not limited to these values.

[0361] Here, MY refers to the number of medals acquired from the point where the net number of medals for the day (the cumulative difference between the number of medals inserted and the number of medals paid out in a single game (paid out - inserted)) was minimized (the point where the losing streak was the worst). Also, the stopping of all reels refers to the state of waiting to start the game, and more precisely, it means that the game medal insertion ready lamp 124 is lit.

[0362] Figure 29(A) shows a time chart of the demo screen transition in the case of a bet of 0 in this embodiment (case (A) and (1) above). In this case, as shown in Figure 29(A), the liquid crystal display device 157 continues to display the game screen d1 (Figure 30(B-1) described later) from the previous game, but since no medals are bet, the demo screen d2 (Figures 30(B-2) to (B-4) described later; the configuration of demo screen d2 will be described in detail later) starts to be displayed at time t2, after the waiting time M has elapsed from time t1 when all reels have stopped. The demo screen d2 is displayed from time t1 until time t3 when the predetermined number of 3 medals are bet.

[0363] Figure 29(B) shows a time chart regarding the transition to the demo screen in the case of a bet of 2 in the conventional system. Conventionally, if the number of medals bet was less than the specified number, as shown in Figure 29(B), the demo screen d2 was not displayed even at time t5, when the waiting time M had elapsed from the time the bet was made t4, and the game screen d1 continued to be displayed. In other words, conventionally, the system was configured so that the demo screen d2 would not be displayed if the number of medals bet was less than the specified number.

[0364] Therefore, conventionally, even if a game was ended with fewer than the required number of tokens bet, the demo screen would not appear, making it difficult to recognize the machine as vacant, and resulting in the problem of machines being left vacant for extended periods.

[0365] In contrast, Figure 30(A) shows a time chart relating to the demo screen transition in the case of a bet of 2 in this embodiment (the case of (A) and (2) above). In this case, as shown in Figure 30(A), the liquid crystal display device 157 continues to display the game screen d1 from the previous game, but the demo screen d2 is displayed at time t5, after the waiting time M has elapsed from the time t4 when a number of medals less than the prescribed number is bet. The demo screen d2 is displayed until time t3 when the prescribed number of 3 medals is bet, similar to Figure 29(A).

[0366] As a result, in this embodiment, even if the game ends with fewer than the specified number of tokens bet, the game transitions to demo screen d2, making it easier to recognize that the machine is vacant. In other words, it is possible to prevent machines from being left vacant for extended periods.

[0367] In this embodiment, the slot machine 100 allows the bet button 132 to be operated even if there are only one or two credits, and one or two tokens are inserted.

[0368] Here, we will explain the configuration and display examples of demo screen d2 using Figures 29(A), 30(A), and 30(B) mentioned above.

[0369] Figure 30(B-1) shows an example of the game screen d1 display, and Figures 30(B-2) to (B-4) show examples of the demo screen d2 display. In this embodiment, the demo screen d2 is composed of, in detail, a performance introduction display screen d2A, a machine name display screen d2B, a warning display screen d2C, and a company name display screen d2D, as shown in Figures 29(A) and 30(A). Each demo screen is controlled to be displayed sequentially and cyclically as a predetermined display time elapses, in the order of performance introduction display screen d2A → machine name display screen d2B → warning display screen d2C → company name display screen d2D → performance introduction display screen d2A →...

[0370] The performance introduction screen d2A is a demo display screen that introduces the performances performed in slot machine 100, as shown in Figure 30(B-2). The model name display screen d2B is a demo display screen that displays the model name of slot machine 100 (not shown). The warning display screen d2C is a demo display screen that displays a message warning against excessive gambling (for example, "Be careful not to get addicted!") as shown in Figure 30(B-3). The company name display screen d2D is a demo display screen that displays the name of the company that manufactures and sells slot machine 100 (not shown).

[0371] Furthermore, the demo screen d2 of this embodiment displays the maximum number of photos d10, as shown in Figures 29(A) and 30(A). The maximum number of photos d10 is an image that displays the maximum MY value for the day. In this embodiment, the maximum number of photos d10 is displayed when the maximum MY value is 1000 or more, and is not displayed when the maximum MY value is less than 1000, so the number displayed in the maximum number of photos d10 will be 1000 or more. As shown in Figures 30(B-2) to (B-4), the maximum number of photos d10 is displayed together with the demo screen d2.

[0372] As a result, the maximum number of coins display d10 of this embodiment is displayed on the demo screen d2 only when the number of coins won is such that it gives the player a sense of satisfaction, thus preventing the player from getting a negative impression of the maximum number of coins display d10. Furthermore, when the demo screen d2 is displayed while the player is not playing, the maximum number of coins display d10 is displayed only when the maximum MY value for the day is equal to or greater than a predetermined number (1000 coins), thus appealing to players that the available machine is a "payout machine" and encouraging them to play. Conversely, when the maximum MY value for the day is less than a predetermined number (1000 coins), the maximum number of coins display d10 is not displayed, thus preventing the player from getting a negative impression that the machine is a "non-payout machine".

[0373] Furthermore, since the maximum number of coins d10 is displayed using the LCD display device 157 of the slot machine 100, it is possible to easily find an available machine without being distracted by the data display of each machine. As a result, it is possible to prevent disputes between customers where a player starts playing on a machine that has been reserved by another player.

[0374] Furthermore, the maximum number of coins displayed d10 on demo screen d2 eliminates the need for player operation compared to transitioning from the menu screen to display rankings of acquired coins, displays of acquired coins, and the number of times the game has been controlled to a favorable state.

[0375] Furthermore, if the game ends with fewer than the specified number of medals bet, the system transitions to demo screen d2 and displays the maximum number of medals d10, thus preventing machines from being left vacant for extended periods and encouraging players to continue playing.

[0376] In this embodiment, the maximum number of images d10 is displayed on the performance introduction screen d2A, the model name display screen d2B, and the warning display screen d2C, but is configured not to be displayed on the company name display screen d2D, however, it is not limited to this configuration. For example, the demo screen d2 may not be displayed on the warning display screen d2C, or the demo screen d2 may be displayed on the company name display screen d2D.

[0377] <Slump graph> Next, using Figure 31, the display of the maximum number of coins d10 and the pre-notification d20 according to this embodiment will be explained. Figure 31 is an example of a slump graph showing the change in the number of coins for the slot machine 100.

[0378] The slot machine 100 of this embodiment has a complete function. The complete function is a function that makes it impossible to play for the day when the number of coins won (MY) for the day reaches a predetermined number MA (for example, 19,000 coins in this embodiment). The advance notification d20 is a visual display that notifies the player that the MY for the day is approaching this predetermined number MA. In this embodiment, when MY reaches 18,500 coins or more, the advance notification d20 is executed and the number of coins remaining until the predetermined number MA is displayed.

[0379] Figure 30(B-4) shows an example of the display of the pre-notification d20 on the demo screen d2. As shown in Figure 30(B-4), the pre-notification d20 is displayed on the demo screen d2 together with the maximum number display d10. Note that the maximum number display d10 is displayed larger than the pre-notification d20 and is therefore more prominent.

[0380] According to Figure 31, the minimum difference in the number of tokens is -2000 at time T1, so MY is calculated based on the number of tokens gained from this minimum value of -2000. From time T0 to time T4, MY is 1000 or less, so the maximum number of tokens display d10 is not displayed on demo screen d2. Hereafter, the section in which the maximum number of tokens display d10 is not displayed on demo screen d2 will be called the "maximum number not displayed section," and the section in which the maximum number of tokens display d10 is displayed on demo screen d2 will be called the "maximum number displayed section." The section from time T0 to time T4 is the maximum number not displayed section. On the other hand, the section from time T4 onward is the section after MY has reached 1000 or more, so it is the maximum number displayed section.

[0381] From time point T4 to time point T5, the MY value increases, so the value of the maximum number of medals displayed d10 is updated (shown as "Maximum number updated" in Figure 31). Then, at time T5, the maximum number of medals displayed d10 is 1500. Subsequently, from time point T5 to time point T9, the MY value decreases or increases, but since MY does not exceed 1500, the value of the maximum number of medals displayed d10 remains at 1500 (shown as "Maximum 1500 medals" in Figure 31). In this way, even in periods when the number of medals decreases, the maximum MY value up to that point is displayed, so the machine can be promoted as having the potential to pay out the maximum number of medals displayed d10.

[0382] In the interval from time T9 to time T11, the MY value increases, so the value of the maximum number of medals displayed d10 is updated. Here, in the interval from time T10 to time T11, although the state is normal and not AT state, the number of medals acquired has increased slightly, so the value of the maximum number of medals displayed d10 is updated. Thus, in this embodiment, the updated maximum number of medals displayed d10 is shown on demo screen d2 whether it is AT state or normal state. Then, at time T11, the maximum number of medals displayed d10 of 3020 is displayed. Subsequently, in the interval from time T11 to time T13, the MY value decreases or increases, but since MY does not exceed 3020, the value of the maximum number of medals displayed d10 remains 3020 (shown as "Maximum 3020 medals" in Figure 31).

[0383] From time point T13 to time point T15, the MY value increases, so the value of the maximum number of coins displayed d10 is updated during this period. At time point T14, the MY value reaches 18500, so the display of the advance notification d20 begins from time T14 onward. The advance notification d20 is displayed until MY reaches 19500 coins. At time T15, the maximum number of coins displayed d10 is 18700. Subsequently, from time point T15 to time point T17, the MY value decreases or increases, but MY does not exceed 18700, so the value of the maximum number of coins displayed d10 remains at 18700 (shown as "Maximum 18700 coins" in Figure 31).

[0384] In this embodiment, the maximum number of coins display d10 is displayed only after the MY value for the day reaches 1000 or more, thus preventing the negative impression of a "machine that doesn't pay out" and thereby encouraging players to continue playing. Furthermore, even if the MY value decreases, the maximum MY value up to that point is displayed, allowing the machine to be appealing as having potential. Moreover, if the MY value is 18500 or more, the advance notification d20 is displayed along with the maximum number of coins display d10, allowing players to know the remaining number of coins up to the specified number of 19000.

[0385] While Figure 31 shows a slump graph where the number of tokens dispensed increased from time T8, we will now explain the case where the number of tokens dispensed did not increase after time T8. Even if the number of tokens dispensed continues to decrease from time T8 and the net number of tokens falls below -1500, the maximum number of tokens display d10 will still show "1500". This is because the maximum MY (maximum increase from the minimum value) of 1500 has not been updated. Subsequently, for example, if the number of tokens dispensed increases after reaching a net number of tokens of -3000, and the number of tokens dispensed does not increase to a net number of tokens of -1500, the maximum MY of 1500 will not be updated, so the maximum number of tokens display d10 will show "1500". However, if the number of tokens dispensed increases beyond -1500, the maximum MY will be updated beyond 1500, and the maximum number of tokens display d10 will show the updated maximum MY value.

[0386] <How the slot machine works> • Maximum number of pages update process Next, the maximum number of sheets update process will be explained using Figure 32. Figure 32 is a sequence diagram showing the flow of the maximum number of sheets update process executed by the main control unit 300 and the first sub-control unit 400.

[0387] When the main control unit 300 enters a state of waiting to start a game, it transmits the current MY value (MY value up to the previous game) to the first sub-control unit 400 (step S101). Here, the state of waiting to start a game means that it is possible to insert tokens, or more precisely, the state in which the token insertion ready lamp 124 is lit. As a result, the first sub-control unit 400 receives the current MY value NV.

[0388] Next, the main control unit 300 receives a game start operation by operating the start lever 135 (step S102) and waits until the reels 110 to 112 start rotating (step S103). Meanwhile, the first sub-control unit 400 refers to the MY value transmitted in step S101 during this wait time (step S201). As a result, the first sub-control unit 400 grasps the current MY value NV.

[0389] Next, when the wait time is finished, the main control unit 300 rotates the reels 110 to 112 (step S104), and when it receives a stop operation from the stop buttons 137 to 139 (step S105), it stops the corresponding reels 110 to 112. Based on the stopping patterns of all reels 110 to 112, the main control unit 300 performs a prize determination process and a medal payout process (step S106). In the prize determination process, if a combination of symbols corresponding to any winning combination is displayed on an activated winning line, it is determined that a prize has been won. In the medal payout process, if a prize that is payoutable has been won, the number of medals corresponding to that winning combination is paid out. Also in step S106, the main control unit 300 transmits the number of medals inserted BV and the number of medals paid out OV for the game to the first sub-control unit 400.

[0390] As a result, the first sub-control unit 400 receives the number of tokens inserted BV and the number of tokens paid out OV in the game (step S202) and calculates the remaining number of tokens ZV until the complete function is activated (step S203). Specifically, the remaining number of tokens ZV = specified number of tokens MA - received MY value NV - (number of tokens paid out OV - number of tokens inserted BV). For example, if the specified number of tokens MA is 19000, the MY value NV is 5000, the number of tokens inserted is 3, and the number of tokens paid out is 10, the remaining number of tokens ZV will be 13993.

[0391] Next, the first sub-control unit 400 calculates a new MY value (hereinafter referred to as "this MY value") NV that reflects the current game. Specifically, this MY value NV = prescribed number of coins MA - remaining number of coins ZV. For example, if the prescribed number of coins MA is 19000 and the remaining number of coins ZV calculated in step S203 is 13993, then this MY value NV will be 5007 coins.

[0392] Next, the first sub-control unit 400 determines whether the current MY value NV is greater than the current maximum number of sheets display d10 display value DV (hereinafter also referred to as the "demo MY display value") (step S205). If the current MY value NV is greater than the demo MY display value DV (step S205: YES), the first sub-control unit 400 sets the current MY value NV to the demo MY display value DV (step S206). Otherwise (step S205: NO), it terminates the maximum number of sheets update process.

[0393] Meanwhile, after completing the processing in step S106, the main control unit 300 performs a counter update process to calculate MY (step S107) and returns to step S101.

[0394] Thus, according to the maximum number update process of this embodiment, the demo MY display value is updated only when the current MY value is greater than the demo MY display value. Therefore, the demo MY display value does not decrease, but only remains the same or increases. In other words, the maximum number display d10 shown on the demo screen d2 does not decrease, which can encourage players to continue playing.

[0395] • Maximum number of pages display processing Next, the maximum number of pages display process (hereinafter simply referred to as "maximum number of pages display process") in the demo screen d2 will be explained using Figures 33(A) and (B). Figure 33(A) is a flowchart showing the flow of the maximum number of pages display process executed by the second sub-control unit 500. The maximum number of pages display process is executed at predetermined intervals (timer interrupt time).

[0396] The second sub-control unit 500 determines whether it has detected either a display marker or a hide marker (steps S301, S305). Here, the display marker is a marker that indicates the start of displaying the demo MY display value DV on the screen while the demo screen d2 is being displayed, and the hide marker is a marker that indicates the start of hiding the demo MY display value DV on the screen. In this embodiment, as shown in Figure 33(C-1), a display marker is placed at the beginning of the performance introduction screen d2A that constitutes the demo screen d2, and a hide marker is placed at the beginning of the company name screen d2D. Therefore, if a display marker is detected on the currently displayed demo screen d2, the system is controlled to display the demo MY display value DV on the screen thereafter, and if a hide marker is detected, the system is controlled not to display the demo MY display value DV on the screen thereafter.

[0397] When the second sub-control unit 500 detects a display marker (step S301: YES), specifically, in the performance introduction screen d2A, the model name screen d2B, and the warning screen d2C, it sets the current value of demo MY display value DV to the extended command "Demo MY value" (step S302), and then sets the display mode corresponding to the current value of demo MY display value DV to the extended command "Demo MY color" (step S303). After the processing in step S303, the process proceeds to step S307.

[0398] Here, the extended command is a parameter associated with the liquid crystal command as shown in Figure 33(B). In a predetermined bit position of the 1-byte liquid crystal command, the "Demo MY Numerical Value" indicating the value of Demo MY Display Value DV and the "Demo MY Color" indicating the color of Demo MY Display Value DV are stored. Specifically, in this embodiment, the Demo MY Color is set to indicate whether to display or not, and the color if displayed, according to the value of Demo MY Display Value DV. Specifically, (1) if Demo MY Display Value DV ≤ 999, it is hidden; (2) if Demo MY Display Value DV ≤ 2999, it is silver; (3) if Demo MY Display Value DV ≤ 4999, it is gold; and (4) if Demo MY Display Value DV ≥ 5000, it is rainbow-colored. Thus, in step S303, the display or not and the display color are set.

[0399] Furthermore, if the second sub-control unit 500 detects a hidden marker (step S305: YES), it sets the extended command "Demo MY Color" to "Hidden" (step S306). After the processing in step S306, the process proceeds to step S307.

[0400] On the other hand, if the second sub-control unit 500 does not detect either the display marker or the non-display marker (step S301: NO, step S305: NO), it proceeds to step S307.

[0401] Next, the second sub-control unit 500 performs a display update process (step S307). In the display update process, an image is displayed on the liquid crystal display device 157 based on the value set in the liquid crystal display command.

[0402] As described above, with the maximum number of tokens display processing of this embodiment, the demo MY display value is displayed on demo screen d2 only when MY is 1000 or more, so it is possible to appeal to players by highlighting the tokens on available machines and encouraging them to play. In addition, the display color is changed according to the value of the demo MY display value, so the token situation can be visually appealed to by the display color. Furthermore, since the display and hiding of the demo MY display value are controlled by the display marker and the hide marker, it is possible to flexibly respond to changes in the configuration of demo screen d2.

[0403] In this embodiment, even if the demo MY display value DV is less than 1000 sheets, the "Demo MY value" is set but the "Demo MY color" is hidden, thereby preventing the display of the maximum number of sheets d10 on the demo screen d2 (first method). However, other control methods may be used to prevent the display of the maximum number of sheets d10 on the demo screen d2 when the demo MY display value DV is less than 1000 sheets. For example, if the demo MY display value DV is less than 1000 sheets, the "Demo MY value" may not be set (second method). The first method has the advantage of reducing the amount of program code, but it also has the disadvantage that if there is a problem with the data, the maximum number of sheets d10 may be displayed at an unintended time. On the other hand, the second method has the advantage of being able to control display / hide more reliably, but it also has the disadvantage that the amount of program code increases because a branching algorithm is added.

[0404] In this embodiment, as shown in Figure 33(C-1), a display marker is placed at the beginning of the presentation introduction screen d2A and a hide marker is placed at the beginning of the company name screen d2D. However, as shown in 7(C-2), a hide marker may be placed at the beginning of the company name screen d2D and a display marker at the end of the company name screen d2D. The same control as shown in Figure 33(C-1) can be performed.

[0405] <Variation> In this embodiment, the maximum number of tokens display d10 displays the maximum MY value for the day, but it may also display the maximum number of tokens paid out. In the case of the number of tokens paid out, the number of tokens bet is not taken into consideration, so a larger number can be displayed, and the appeal of winning tokens can be further emphasized. In addition, in this embodiment, the maximum number of tokens display d10 reflects the difference in the number of tokens obtained by irregular button presses, but it may be configured so that the difference in tokens is not reflected in the case of irregular button presses. It is possible to display a larger number of tokens than the number of tokens o...
