[0034] The power supply board 10A supplies DC 24V and DC 12V power to the sub-control board 90. Note that a relay board (not shown) may be provided, and the relay board relays the power output from the power supply board 10A to the sub-control board 90. The sub-control board 90 includes a power generation unit 91 (power supply IC). The power generation unit 91 generates DC 5V or DC 3.3V power from the DC 12V power received from the power supply board 10A (relay board) and supplies power to the logic circuit inside the sub-control board 90.

[0035] Although illustration is omitted, the sub-control board 90 may generate power of DC1.05V from power of DC12V and supply power to the logic circuit in the sub-control board 90.

[0036] The sub-control board 90 supplies power of DC12V and DC24V to the sub-control unit 200. Also, the sub-control board 90 supplies the generated power of DC5V to the sub-control unit 200. The sub-control unit 200 comprehensively shows a plurality of sub-control devices that input signals from or output signals to the sub-control board 90.

[0037] Examples of the sub-control devices constituting the sub-control unit 200 include a liquid crystal display, a lighting device 25 (lamp), a speaker, an effect button 36, a movable prop, etc. The electric elements in each sub-control device of the sub-control unit 200 operate by receiving power supply (for example, DC12V, DC24V) from the sub-control board 90. Note that there may be a sub-control device that is supplied with power without passing through the sub-control board 90.

[0038] FIG. 5 is a block diagram showing the configuration of the sub-control board 90. The sub-control board 90 includes a CPU 300 as control means (effect control means). Also, the sub-control board 90 includes a control ROM 301, a crystal oscillator 302, a RAM 303, and a watchdog timer IC 304. A program related to the control of effects is stored in the control ROM 301. The CPU 300 accesses the control ROM 301 via the CPU bus and controls the effects by executing the program stored in the control ROM 301. The watchdog timer IC 304 is connected to the reset terminal of the CPU 300 and outputs a reset signal to the CPU 300 when a predetermined condition is satisfied (for example, when it is detected that the voltage is unstable). The RAM 303 serves as a storage area for backup data. The crystal oscillator 302 generates a clock signal of a predetermined frequency.

[0039] The effect determination unit 321 of the CPU 300 determines the effect content to be executed based on various commands transmitted from the main control board 80, input signals from the effect buttons 36, and the like. Further, the display control unit 322, the audio control unit 323, the lamp control unit 324, and the motor control unit 325 of the CPU 300 control the execution of the effects determined by the effect determination unit 321.

[0040] (Image) The VDP 305 is a processor that performs image processing (drawing processing) related to the display of an image (video) on the liquid crystal display in accordance with commands from the display control unit 322 and is integrated on a single chip together with the CPU 300. The VDP 305 incorporates a VRAM and a decoder. The display control unit 322 controls the VDP 305 based on the determined effect content and performs control related to the display on the liquid crystal display. The display control unit 322 executes liquid crystal drawing processing at a predetermined period (for example, 60 times per second = 60 FPS frame rate). In the liquid crystal drawing processing, a command (information) for instructing the drawing content is constructed for the VDP 305. The VDP 305 reads out necessary drawing materials from the image / audio ROM 310 based on the command and performs drawing (generates image data indicating a frame image of one frame on the frame buffer), generates a liquid crystal signal, and outputs it to the liquid crystal substrate. The liquid crystal signal consists of, for example, an input video signal (R, G, B) and an input control signal. Examples of the input control signal include a horizontal synchronization signal (HSYNC), a vertical synchronization signal (VSYNC), a clock signal (CLK), and a data enable signal (DE).

[0041] The liquid crystal substrate is provided with a signal conversion circuit (signal conversion means), and the signal conversion circuit generates a driving signal to be transmitted to the liquid crystal display based on the input liquid crystal signal. The signal input to the liquid crystal substrate is converted by the signal conversion circuit, and the generated signal is input to the liquid crystal display. As a result, in the display area of the liquid crystal display, for example, an image (still image) of 60 frames per second is displayed, and a production image of a moving image is displayed. Note that one frame may be referred to as a "frame". For example, in the case of a production image (production pattern) with a production time of 60 seconds, the production image is composed of a total of 3600 frames of 60 seconds × 60 frames.

[0042] (Voice) The voice IC 306 controls the output of voice from the speaker according to a command from the voice control unit 323. The voice IC 306 is integrated on a single chip together with the CPU 300. The voice IC 306 incorporates a decoder. Also, the voice IC 306 is connected to the amplifier 307. The voice control unit 323 controls the voice IC 306 based on the determined production content and performs control regarding the output of voice from the speaker. The voice control unit 323 transmits a command instructing the voice to be output to the voice IC 306. The voice IC 306 reads out necessary voice materials from the image / voice ROM 310 based on the command, generates a voice signal, and outputs it. The amplifier 307 has a function of converting a signal input from the voice IC 306 from a digital signal to an analog signal and a function as an amplifier. The amplifier 307 drives the speaker based on the signal (voice signal) sent from the voice IC 306 and causes the speaker to output sound. Note that the voice IC 306 can control the output volume from the speaker based on an input signal from the volume adjustment switch 95.

[0043] In the present embodiment, it is assumed that the amplifier 307 is arranged on the sub-control board 90, but it is not limited to this, and the amplifier 307 may be arranged on a board different from the sub-control board 90.

[0044] (Movable prop) In this embodiment, in the front door 20, a movable component effect in which a movable component (movable body) operates upon a predetermined trigger can be executed. The motor control unit 325 controls the operation of a motor that serves as a drive source for the movable component. Based on the determined effect content, the motor control unit 325 generates a command (motor control signal) and outputs it to the driver IC on the movable component control board. The movable component control board is a board that controls the operation of the motor. Based on the input motor control signal, the driver IC controls the voltage applied to the motor. The operation of the motor is controlled via the driver IC on the movable component control board. Note that the motor control unit 325 may be provided integrally with the CPU 300 or may be provided separately from the CPU 300.

[0045] In the above description, the motor control unit 325 is assumed to control the operation of the motor that serves as the drive source for the movable component. However, the motor control unit 325 may control the operation of the motor that serves as the drive source for the effect button 36. That is, the effect button 36 may be configured to execute an effect in which it vibrates upon a predetermined trigger, and the motor control unit 325 may control the operation of the motor that vibrates the effect button 36.

[0046] (Lamp) The lamp control unit 324 controls the lighting patterns (including color and brightness) of various lights (lamps) provided in the slot machine 100. Based on the determined effect content, the lamp control unit 324 generates a command (lighting control signal) and outputs it to the driver IC on the electrical decoration board. The lamp control unit 324 may be provided integrally with the CPU 300 or may be provided separately from the CPU 300.

[0047] The electrical decoration board is a board that controls the lighting (emission) of various lamps (LEDs). Based on the input lighting control signal, the driver IC on the electrical decoration board controls the voltage applied to the lamp (LED). The lighting of the lamp is controlled via the driver IC on the electrical decoration board. The lighting control signal is a serial signal.

[0048] In this embodiment, a plurality of decorative substrates are provided. Hereinafter, the decorative substrates will be described in detail.

The side lens left unit 420 and the side lens right unit 430 are symmetric in shape (have a symmetric structure).

[0050] The serial signal is first transmitted to the side lens left unit 420, then from the side lens left unit 420 to the side lens right unit 430, and then from the side lens right unit 430 to the upper design unit 410.

[0051] (Side Lens Left Unit 420) The side lens left unit 420 includes a liquid crystal left slave board 421, a left panel slave LED board 422, and a liquid crystal left middle and upper slave LED board 423. The connector CN3 of the upper connection board 500 and the connector CN1 of the liquid crystal left slave board 421 are connected by a harness X1.

[0052] Inside the left side lens unit 420, the connector CN6 of the left liquid crystal slave board 421 and the connector CN1 of the left panel slave LED board 422 are connected by a harness L1. Also, the connector CN3 of the left liquid crystal slave board 421 and the connector CN1 of the upper middle left liquid crystal slave LED board 423 are connected by a harness L2. The harness L1 and the harness L2 are 10-pin (corresponding to 10 pins) harnesses.

[0053] (Right side lens unit 430) The right side lens unit 430 includes a right liquid crystal slave board 431, a right panel slave LED board 432, and an upper middle right liquid crystal slave LED board 433. The connector CN4 of the upper connection board 500 and the connector CN1 of the right liquid crystal slave board 431 are connected by a harness X2.

[0054] Inside the right side lens unit 430, the connector CN6 of the right liquid crystal slave board 431 and the connector CN1 of the right panel slave LED board 432 are connected by a harness R1. The connector CN3 of the right liquid crystal slave board 431 and the connector CN1 of the upper middle right liquid crystal slave LED board 433 are connected by a harness R2. The harness R1 and the harness R2 are 10-pin harnesses.

[0055] (Upper design unit 410) The upper design unit 410 includes an upper middle left slave board 411 and an upper middle right slave board 412. The connector CN2 of the upper connection board 500 and the connector CN1 of the upper middle left slave board 411 are connected by a harness X3. Inside the upper design unit 410, the connector CN2 of the upper middle left slave board 411 and the connector CN1 of the upper middle right slave board 412 are connected by a harness U1. The harness U1 is an 8-pin harness.

[0056] As shown in FIG. 7, in this embodiment, each driver IC is cascade-connected in the upper serial connection configuration. The serial signal output from the sub-control board 90 is input to the driver IC 421a (LED driver) of the liquid crystal left slave board 421. The serial signal output from the driver IC 421a of the liquid crystal left slave board 421 is input to the driver IC 422a of the left panel slave LED board 422 via the harness L1. The serial signal output from the driver IC 422a of the left panel slave LED board 422 is input to the driver IC 423a of the liquid crystal left upper middle slave LED board 423 via the harness L1, the liquid crystal left slave board 421, and the harness L2. The serial signal output from the driver IC 423a of the liquid crystal left upper middle slave LED board 423 is output to the liquid crystal left slave board 421 via the harness L2. The serial signal is input to the driver IC 431a of the liquid crystal right slave board 431 via the harness X1, the upper connection board 500, and the harness X2.

[0057] The serial signal output from the driver IC 431a of the liquid crystal right slave board 431 is input to the driver IC 432a of the right panel slave LED board 432 via the harness R1. The serial signal output from the driver IC 432a of the right panel slave LED board 432 is input to the driver IC 433a of the liquid crystal right upper middle slave LED board 433 via the harness R1, the liquid crystal right slave board 431, and the harness R2. The serial signal output from the driver IC 433a of the liquid crystal right upper middle slave LED board 433 is output to the liquid crystal right slave board 431 via the harness R2. The serial signal is input to the driver IC 411a of the upper left middle slave board 411 via the harness X2, the upper connection board 500, and the harness X3.

[0058] The serial signal output from the driver IC411a of the upper left middle slave board 411 is input to the driver IC411b of the upper left middle slave board 411, and the serial signal output from the driver IC411b of the upper left middle slave board 411 is input to the driver IC412a of the upper right middle slave board 412 via the harness U1.

[0059] Although the description is omitted due to duplication, the clock signal output from the sub-control board 90 is also transmitted (transferred) through the same path as the serial signal.

[0060] Also, although not shown in FIG. 7, LEDs are mounted on each board constituting the side lens left unit 420, the side lens right unit 430, and the upper design unit 410, and the driver IC of each board lights up the LED based on the reception of the serial signal.

[0061] The sub-control board 90 can output DC5V power to other boards and the like. The DC5V power includes "+DC5V" (first power) constantly output by the sub-control board 90, "+DC5V_TP" (third power) and "+DC5V_BM" (second power) whose output ON / OFF can be controlled by the sub-control board 90.

[0062] As shown in FIG. 7, the sub-control board 90 can supply the power of "+DC5V_TP" to the liquid crystal left slave board 421, the left panel slave LED board 422, the liquid crystal left upper middle slave LED board 423, the liquid crystal right slave board 431, the right panel slave LED board 432, the liquid crystal right upper middle slave LED board 433, the upper left middle slave board 411, and the upper right middle slave board 412 in the upper serial connection configuration, and this power serves as the power supply for the driver IC of each board.

[0063] When a predetermined error (defect, abnormality) occurs or the like, the sub-control board 90 can cut off (turn off) the supply of the power of "+DC5V_TP". Thereby, the operation of each driver IC can be stopped.

[0064] (Harness L1) Regarding the harness L1 shown in FIG. 6, one of the 10 pins is a pin corresponding to the serial signal transmitted from the liquid crystal left slave substrate 421 to the left panel slave LED substrate 422. Also, one of the 10 pins is a pin corresponding to the clock signal transmitted from the liquid crystal left slave substrate 421 to the left panel slave LED substrate 422. Also, one of the 10 pins is a pin corresponding to the serial signal (return signal) transmitted from the left panel slave LED substrate 422 to the liquid crystal left slave substrate 421. Also, one of the 10 pins is a pin corresponding to the clock signal (return signal) transmitted from the left panel slave LED substrate 422 to the liquid crystal left slave substrate 421.

[0065] (Harness L2) Regarding the harness L2, one of the 10 pins is a pin corresponding to the serial signal transmitted from the liquid crystal left slave substrate 421 to the liquid crystal left upper middle slave LED substrate 423. Also, one of the 10 pins is a pin corresponding to the clock signal transmitted from the liquid crystal left slave substrate 421 to the liquid crystal left upper middle slave LED substrate 423. Also, one of the 10 pins is a pin corresponding to the serial signal (return signal) transmitted from the liquid crystal left upper middle slave LED substrate 423 to the liquid crystal left slave substrate 421. Also, one of the 10 pins is a pin corresponding to the clock signal (return signal) transmitted from the liquid crystal left upper middle slave LED substrate 423 to the liquid crystal left slave substrate 421.

[0066] The harness L1 has a first length corresponding to the distance between the liquid crystal left slave substrate 421 and the left panel slave LED substrate 422, and the harness L2 has a second length corresponding to the distance between the liquid crystal left slave substrate 421 and the liquid crystal left upper middle slave LED substrate 423. In this embodiment, the first length and the second length are different, and the harness L1 and the harness L2 are harnesses with different specifications.

[0067] (Harness R1) Regarding the harness R1, one of the 10 pins is a pin corresponding to the serial signal transmitted from the liquid crystal right slave substrate 431 to the right panel slave LED substrate 432. Also, one of the 10 pins is a pin corresponding to the clock signal transmitted from the liquid crystal right slave substrate 431 to the right panel slave LED substrate 432. Also, one of the 10 pins is a pin corresponding to the serial signal (return signal) transmitted from the right panel slave LED substrate 432 to the liquid crystal right slave substrate 431. Also, one of the 10 pins is a pin corresponding to the clock signal (return signal) transmitted from the right panel slave LED substrate 432 to the liquid crystal right slave substrate 431.

[0068] (Harness R2) Regarding the harness R2, one of the 10 pins is a pin corresponding to the serial signal transmitted from the liquid crystal right slave substrate 431 to the liquid crystal right upper middle slave LED substrate 433. Also, one of the 10 pins is a pin corresponding to the clock signal transmitted from the liquid crystal right slave substrate 431 to the liquid crystal right upper middle slave LED substrate 433. Also, one of the 10 pins is a pin corresponding to the serial signal (return signal) transmitted from the liquid crystal right upper middle slave LED substrate 433 to the liquid crystal right slave substrate 431. Also, one of the 10 pins corresponds to a clock signal (return signal) transmitted from the liquid crystal upper right slave LED board 433 to the liquid crystal right slave board 431.

[0069] The harness R1 has a third length corresponding to the distance between the liquid crystal right slave board 431 and the right panel slave LED board 432, and the harness R2 has a fourth length corresponding to the distance between the liquid crystal right slave board 431 and the liquid crystal upper right slave LED board 433. In this embodiment, the third length and the fourth length are different, and the harness R1 and the harness R2 are harnesses with different specifications.

[0070] (Commonization of harnesses) Since the side lens left unit 420 and the side lens right unit 430 have a symmetric structure, the first length related to the harness L1 and the third length related to the harness R1 are the same. Also, the second length related to the harness L2 and the fourth length related to the harness R2 are the same. Also, as described above, the harness L1 and the harness R1 have 10 pins, and the harness L2 and the harness R2 have 10 pins. Therefore, the harness L1 and the harness R1 can be the same (common) parts. In other words, a common specific harness (first specific harness) can be used. Also, the harness L2 and the harness R2 can be the same (common) parts. In other words, a common specific harness (second specific harness) can be used.

[0071] By sharing parts, the cost can be reduced compared to the case of providing them separately. Also, when providing them separately, it is necessary to identify whether it is for the right side or the left side, but by sharing parts, the identification can be omitted. Also, when an operator assembles, the trouble of checking whether it is for the right side or the left side can be saved (the work burden can be reduced).

[0072] In addition, since the harness L1 and the harness R1 are the same component, and the harness L2 and the harness R2 are the same component, a common jig (inspection jig) can be used when inspecting the left side lens unit 420 and when inspecting the right side lens unit 430. Therefore, the cost can be reduced compared to the case of providing separate jigs.

[0073] (Harness U1) Regarding the harness U1, one of the 8 pins is a pin corresponding to the serial signal transmitted from the upper left middle slave board 411 to the upper right middle slave board 412. Also, one of the 8 pins is a pin corresponding to the clock signal transmitted from the upper left middle slave board 411 to the upper right middle slave board 412. Unlike the harness L1, harness L2, harness R1, and harness R2, the harness U1 has 8 pins (2 pins less) because the pins corresponding to the return signal are not required. For a series of cascade-connected driver ICs, the harness connecting the last driver ICs can have fewer pins because the return signal is not required.

[0074] If the right side lens unit 430 is set as the final stage of connection instead of the upper design unit 410 (when the connection order of the upper design unit 410 and the right side lens unit 430 is reversed), the harness U1 needs to have 10 pins, and the harness R2 can have 8 pins. However, in this case, since the number of pins of the harness L2 (10 pins) and the harness R2 (8 pins) is different, the components cannot be shared. In this embodiment, the left side lens unit 420 and the right side lens unit 430, which have a symmetric structure, are first connected, and then the upper design unit 410 is connected at the subsequent stage. As a result, the same components (harnesses) can be used in the left side lens unit 420 and the right side lens unit 430.

[0075] Note that since the left side lens unit 420 and the right side lens unit 430 are symmetrical, and the harnesses X1 and X2 have the same number of pins and the same length, a common component (specific harness) can be used. The harness X3 has fewer pins than the harnesses X1 and X2 (it cannot be made common with the specific harness). For example, the harnesses X1 and X2 have 8 pins, and the harness X3 has 6 pins.

[0076] Note that for the harnesses X1 and X2, the connector corresponding to one harness (for example, the connector CN4 of the upper connection board 500 corresponding to the harness X2) is made different from the connector corresponding to the other harness (for example, the connector CN3 of the upper connection board 500 corresponding to the harness X1), and the harnesses X1 and X2 are made to have different specifications so as to prevent misassembly.

[0077] In this embodiment, the upper design unit 410, the left side lens unit 420, and the right side lens unit 430 are each assumed to include a plurality of substrates, but each substrate only needs to include at least one substrate on which at least one driver IC is mounted.

[0078] For example, the gaming machine of this embodiment is provided with a control board (sub-control board 90) capable of outputting a serial signal, a first control board (for example, the left panel slave LED board 422) on which a first driver IC (for example, driver IC 422a) for controlling the operation (lighting) of a first operating member (LED) based on the reception of the serial signal is mounted, and a second control board (for example, the right panel slave LED board 432) on which a second driver IC (for example, driver IC 432a) for controlling the operation (lighting) of a second operating member (LED) based on the reception of the serial signal is mounted. A third control board (e.g., the upper right middle slave board 412) on which a third driver IC (e.g., driver IC 412a) for controlling the operation (lighting) of a third operating member (LED) based on the reception of the serial signal is mounted, The first driver IC, the second driver IC, and the third driver IC are cascade-connected, and the serial signal is transmitted to each driver IC in order. Thereby, a new connection method for the driver IC can be provided.

[0079] The third driver IC is the last driver IC in the cascade-connected driver ICs, The control board and the first control board are connected via a first predetermined board (e.g., the liquid crystal left slave board 421), The control board and the second control board are connected via a second predetermined board (e.g., the liquid crystal right slave board 431), The control board and the third control board are connected via a third predetermined board (e.g., the upper left middle slave board 411), A harness (harness L1) connecting the first predetermined board and the first control board and a harness (harness R1) connecting the second predetermined board and the second control board are a common specific harness, A harness (harness U1) connecting the third predetermined board and the third control board is a harness different from the specific harness.

[0080] In the middle of the cascade connection, the harness connecting the boards can be a common specific harness. For this reason, the cost can be reduced compared to the case where components cannot be shared. Also, when components cannot be shared, identification is provided and it is necessary to confirm which harness it corresponds to. By sharing the components, the trouble of confirmation can be saved and the burden on the operator can be reduced.

[0081] Note that it may be configured as follows. The gaming machine of this embodiment A control board (sub-control board 90) capable of outputting a serial signal, A first control board (e.g., the left liquid crystal slave board 421) on which a first driver IC (e.g., driver IC421a) for controlling the operation (lighting) of a first operating member (LED) based on the reception of the serial signal is mounted, A second control board (liquid crystal right slave board 431) on which a second driver IC (e.g., driver IC431a) for controlling the operation (lighting) of a second operating member (LED) based on the reception of the serial signal is mounted, A third control board (upper left middle slave board 411) on which a third driver IC (e.g., driver IC411a) for controlling the operation (lighting) of a third operating member (LED) based on the reception of the serial signal is mounted, and The first driver IC, the second driver IC, and the third driver IC to which the serial signal is transmitted are cascade-connected.

[0082] The third driver IC is the last driver IC in the cascade-connected driver ICs, The control board and the first control board are connected via a first predetermined board (e.g., the upper connection board 500), The control board and the second control board are connected via a second predetermined board (e.g., the upper connection board 500), The control board and the third control board are connected via a third predetermined board (e.g., the upper connection board 500), A harness (harness X1) connecting the first predetermined board and the first control board and a harness (harness X2) connecting the second predetermined board and the second control board are a common specific harness, A harness (harness X3) connecting the third predetermined board and the third control board is a harness different from the specific harness. That is, the first predetermined board, the second predetermined board, and the third predetermined board may be the same board (e.g., the upper connection board 500).

[0083] (Lower serial connection configuration) As shown in FIG. 8, the serial signal output from the sub-control board 90 is output to the lower serial connection configuration (block). The lower serial connection configuration is composed of a reel slave board 610, a lower panel middle slave LED board 620, a lower panel upper left slave LED board 630, a lower panel lower left slave LED board 640, a lower panel lower right slave LED board 650, a lower panel upper right slave LED board 660, and an effect button slave board 670. It can be said that the block is composed of seven boards.

[0084] The serial signal is first sent to the reel slave board 610, then to the lower panel middle slave LED board 620, then to the lower panel upper left slave LED board 630, then to the lower panel lower left slave LED board 640, then to the lower panel lower right slave LED board 650, then to the lower panel upper right slave LED board 660, and finally to the effect button slave board 670.

[0085] CN2 of the reel slave board 610 and the connector CN1 of the lower panel middle slave LED board 620 are connected by a harness Y. The connector CN2 of the lower panel middle slave LED board 620 and the connector CN1 of the lower panel upper left slave LED board 630 are connected by a harness Z1. The connector CN4 of the lower panel middle slave LED board 620 and the connector CN1 of the lower panel lower left slave LED board 640 are connected by a harness Z2. The connector CN5 of the lower panel middle slave LED board 620 and the connector CN1 of the lower panel lower right slave LED board 650 are connected by a harness Z3. The connector CN3 of the lower panel middle slave LED board 620 and the connector CN1 of the lower panel upper right slave LED board 660 are connected by a harness Z4. The connector CN8 of the slave LED board 620 in the lower panel and the connector CN1 of the effect button slave board 670 are connected by a harness Z5.

[0086] As shown in FIG. 9, in this embodiment, each driver IC is cascade-connected in the lower serial connection configuration. The serial signal output from the sub-control board 90 is input to the driver IC610a (LED driver) of the reel slave board 610. The serial signal output from the driver IC610a of the reel slave board 610 is input to the driver IC620a of the slave LED board 620 in the lower panel via the harness Y.

[0087] The serial signal output from the driver IC620a of the slave LED board 620 in the lower panel is input to the driver IC630a of the upper left slave LED board 630 in the lower panel via the harness Z1. The serial signal output from the driver IC630a of the upper left slave LED board 630 in the lower panel is input to the driver IC640a of the lower left slave LED board 640 in the lower panel via the harness Z1, the slave LED board 620 in the lower panel, and the harness Z2. The serial signal output from the driver IC640a of the lower left slave LED board 640 in the lower panel is input to the driver IC650a of the lower right slave LED board 650 in the lower panel via the harness Z2, the slave LED board 620 in the lower panel, and the harness Z3. The serial signal output from the driver IC650a of the lower right slave LED board 650 in the lower panel is input to the driver IC660a of the upper right slave LED board 660 in the lower panel via the harness Z3, the slave LED board 620 in the lower panel, and the harness Z4. The serial signal output from the driver IC660a of the upper right slave LED board 660 in the lower panel is input to the driver IC670a of the effect button slave board 670 via the harness Z4, the slave LED board 620 in the lower panel, and the harness Z5.

[0088] Since it is repetitive, the description will be omitted, but the clock signal output from the sub-control board 90 is also transmitted (sent) through the same path as the serial signal. Note that the harness Z5 has fewer pins than the harnesses Z1 to Z4. Also, the harnesses Z1 to Z4 may have different colors (the colors of the coatings) and be distinguishable.

[0089] Figure 10 shows the slave LED board 620 in the lower panel. The signal from the reel slave board 610 is input to the connector CN1 of the slave LED board 620 in the lower panel. The signal is input to CN2 via the pattern (signal line) on the board, input to the upper left slave LED board 630 in the lower panel via CN2, and the return signal is input to CN2. The signal is input to CN4 via the pattern (signal line) on the board, input to the lower left slave LED board 640 in the lower panel via CN4, and the return signal is input to CN4. The signal is input to CN5 via the pattern (signal line) on the board, input to the lower right slave LED board 650 in the lower panel via CN5, and the return signal is input to CN5. The signal is input to CN3 via the pattern (signal line) on the board, input to the upper right slave LED board 660 in the lower panel via CN3, and the return signal is input to CN3. The signal is input to CN8 via the pattern (signal line) on the board and input to the effect button slave board 670 via CN8. In this embodiment, by connecting the boards so that the serial signal (clock signal) is transmitted in such an order, the routing of the pattern can be minimized in the slave LED board 620 in the lower panel. As a result, space savings can be achieved compared to the case where the routing of the pattern is complex. Also, by minimizing the routing of the pattern, the resistance to noise can be enhanced.

[0090] In Fig. 9, although some illustrations are omitted, LEDs are mounted on the release slave board 610, the lower panel middle slave LED board 620, the lower panel upper left slave LED board 630, the lower panel lower left slave LED board 640, the lower panel lower right slave LED board 650, the lower panel upper right slave LED board 660, and the effect button slave board 670. The driver ICs of each board light up the LEDs based on the reception of serial signals.

[0091] The sub-control board 90 can supply the power of “+DC5V_BM” to the lower panel middle slave LED board 620, the lower panel upper left slave LED board 630, the lower panel lower left slave LED board 640, the lower panel lower right slave LED board 650, the lower panel upper right slave LED board 660, and the effect button slave board 670 in the lower serial connection configuration, and this power serves as the power supply for the driver ICs of each board.

[0092] When a predetermined error (malfunction, abnormality) occurs or the like, the sub-control board 90 can cut off (turn off) the supply of the power of “+DC5V_BM” (the second power). Thereby, the operation of each driver IC can be stopped.

[0093] The sub-control board 90 can supply the power of “+DC5V” (the first power) to the release slave board 610 in the lower serial connection configuration, and this power serves as the power supply for the driver IC 610a. “+DC5V” is the power that is constantly supplied. The driver IC 610a can constantly light up the LED based on the reception of the serial signal. The LED serves as a reel backlight. Inside the reels 15a to 15c (Fig. 2), a reel backlight (LED) that irradiates light toward the upper symbols, middle symbols, and lower symbols on each stopped reel is provided.

[0094] Even if the power supply of "+DC5V_BM" from the sub-control board 90 is cut off when a specified error (defect, abnormality) occurs or the like, the power supply of "+DC5V" from the sub-control board 90 is not cut off. Therefore, the driver IC 610a can turn on the reel backlight based on the reception of a serial signal. In a gaming machine, it is required to ensure the visibility of the reels by preventing the reel backlight from turning off even when an error or the like occurs (it is required that the reel backlight does not turn off at an unintended timing).

[0095] The driver IC 610a can be said to be the leading driver IC of a series of cascaded driver ICs. Since the driver IC 610a is arranged at the head and constantly supplied with "+DC5V", it can turn on the LED based on the reception of a serial signal. If the driver IC 610a is provided in the middle of a series of cascade connections, when an error occurs and the power supply of "+DC5V_BM" is cut off, even if the power supply of "+DC5V" is supplied, the driver IC provided on the previous board does not operate, so the driver IC 610a cannot receive the serial signal. For this reason, there is a problem that the driver IC 610a cannot turn on the reel backlight (the visibility of the reels decreases), but according to the present embodiment, such a problem can be prevented.

[0096] (Effect button slave board) The effect button 36 (see FIG. 1) is configured to be able to light up (emit light). The driver IC 670a on the effect button slave board 670 controls the lighting of the LED for the effect button 36. The gaming machine of the present embodiment is provided with the effect button 36, but there are also gaming machines that do not have the effect button 36 depending on the type (model) of the gaming machine.

[0097] The driver IC670a related to the performance button 36 can be said to be the last driver IC in a series of cascaded driver ICs. Since the driver IC670a is located at the end of the cascaded connection, if the performance button 36 is not provided, it is only necessary to omit (delete) the corresponding unnecessary configuration. In other words, the burden on the designer can be reduced. In addition, it is possible to easily (flexibly) respond to changes in the specifications of the performance button 36. If the driver IC670a is provided in the middle of a series of cascaded connections, it is necessary to change the program, connections, etc. when omitting the driver IC670a, which is time-consuming and increases the burden on the designer. However, according to this embodiment, such problems can be suppressed.

[0098] In this embodiment, The third driver IC (driver IC670a) is the last driver IC in the cascaded driver ICs, The third operating member is the illumination (LED) of the performance button (performance button 36), and the third driver IC controls the lighting of the illumination.

[0099] It is possible to make the response when the specifications of the performance button are changed easier and reduce the burden on the designer.

[0100] Also, in this embodiment, The first operating member is a reel backlight, and the first driver IC (driver IC610a) controls the lighting of the reel backlight, The first driver IC is located in front of the second driver IC and the third driver IC and is supplied with the first power (+DC5V), Even when the supply of the second power (+DC5V_BM) to the second driver IC and the third driver IC is cut off based on the occurrence of a predetermined error, the first driver IC can turn on the reel backlight based on the reception of the serial signal.

[0101] Even if a predetermined error occurs, the reel backlight can be kept lit. This can prevent the visibility of the reel backlight from deteriorating.

[0102] (Second Embodiment) Next, a second embodiment of the present invention will be described. The gaming machine of this embodiment has the same configuration as the gaming machine according to the first embodiment. Therefore, the description of the same configuration as that of the first embodiment will be omitted or simplified.

[0103] As described above, the lower panel 39 (FIG. 1) is irradiated with light from behind and can be lit (emit light). The substrate that irradiates light onto the lower panel 39 has a lower panel middle slave LED substrate 620. FIG. 11 shows a circuit diagram (at least a part) related to the LEDs in the lower panel middle slave LED substrate 620. The driver IC 620a (LED driver) can output a control signal via a predetermined output terminal based on receiving a serial signal, and can control the lighting (emission) of 26 full-color LEDs (LEDs 1 to 26). The full-color LED (RGB LED) is an LED that can emit light in any one of a plurality of colors. Hereinafter, the full-color LED will be simply referred to as an "LED".

[0104] The driver IC 620a (control IC) includes 12 terminals including a first output terminal PO1 (LED1), a second output terminal PO2 (LED2), and a third output terminal PO3 (LED3). In this embodiment, the maximum output current value of the driver IC 620a (each output terminal of the first output terminal PO1, the second output terminal PO2, and the third output terminal PO3) is 30 mA.

[0105] In this embodiment, 26 LEDs can be made to emit light simultaneously using three (three) output terminals of one driver IC620a. The first output terminal PO1 is an output terminal corresponding to the red light emission of the LED, the second output terminal PO2 is an output terminal corresponding to the green light emission of the LED, and the third output terminal PO3 is an output terminal corresponding to the blue light emission of the LED. Hereinafter, red may be referred to as a "specific color", and colors other than red (green and blue) may be referred to as "predetermined colors".

[0106] When lighting one LED in red, the voltage drop (forward voltage) is 2.03V and the forward current is 10.32mA. When lighting one LED in green, the voltage drop (forward voltage) is 3.10V and the forward current is 6.6mA. When lighting one LED in blue, the voltage drop (forward voltage) is 2.67V and the forward current is 3.58mA.

[0107] Each LED has six terminals: a red cathode terminal, a green cathode terminal, a blue cathode terminal, a red anode terminal, a green anode terminal, and a blue anode terminal.

[0108] In the lower panel slave LED board 620, power of +DC5V, +DC12V, and +DC24V is supplied as the power supply voltage. However, when 26 LEDs 1 to 26 are connected in series, the driving voltage is insufficient. Therefore, in this embodiment, four systems (blocks) in which five LEDs are connected in series and one system (block) in which six LEDs are connected in series are connected in parallel with each other (five parallel). In other words, the 26 LEDs use a unit in which a predetermined number (five or six) of LEDs are connected in series as a block, and a plurality of blocks are connected in parallel with each other. Further in other words, the 26 LEDs are divided into five systems, and five (or six) LEDs are arranged in one system.

[0109] Each block has lines related to red, lines related to green, and lines related to blue. In order to make each LED emit red light, a total current of about 52 mA needs to flow through the 5 lines related to red. In order to make each LED emit green light, a total current of about 33 mA needs to flow through the 5 lines related to green. In order to make each LED emit blue light, a total current of about 18 mA needs to flow through the 5 lines related to blue.

[0110] The current value related to the red line (about 52 mA) and the current value related to the green line (about 33 mA) are larger than the maximum output current value (30 mA) of the output terminal of the driver IC620a. Therefore, in this embodiment, an NPN transistor is used (connected) to amplify the current, enabling the LED to emit light (light up) in each color. Note that the current value related to the blue line (about 18 mA) is smaller than the maximum output current value (30 mA) of the output terminal, but an NPN transistor is connected in order to align with red and green (match the specifications).

[0111] The NPN transistors include NPN transistors 701a and 701b related to red light emission, an NPN transistor 702 related to green light emission, and an NPN transistor 703 related to blue light emission. The emitter terminal of each NPN transistor is connected to the ground.

Specifically, the red cathode terminal of LED5 is connected to the red anode terminal of LED4. The green cathode terminal of LED5 is connected to the green anode terminal of LED4.

Each cathode of LED13 is connected to each anode of LED12. Each cathode of LED12 is connected to each anode of LED11. Each cathode of LED11 is connected to the collector terminal of an NPN transistor via a resistor. The cathode related to the red color of LED11 (red cathode terminal) is connected to the collector terminal of NPN transistor 701a via two resistors (R65, R66). The cathode related to the green color of LED11 (green cathode terminal) is connected to the collector terminal of NPN transistor 702 via one resistor (R67). The cathode related to the blue color of LED11 (blue cathode terminal) is connected to the collector terminal of the NPN transistor 703 via one resistor (R68).

[0115] (Block D) In block D, LEDs 17 to 21 are connected in series. Each anode of LED21 (red anode terminal, green anode terminal, and blue anode terminal) is connected to the 24V power line.

The cathode related to the blue color of LED17 (blue cathode terminal) is connected to the collector terminal of the NPN transistor 703 via one resistor (R73).

[0116] (Block E) In block E, LEDs 22 to 26 are connected in series. Each anode of LED26 (red anode terminal, green anode terminal, and blue anode terminal) is connected to the 24V power line. Each cathode of LED26 is connected to each anode of LED25. Each cathode of LED25 is connected to each anode of LED24. Each cathode of LED24 is connected to each anode of LED23.

The cathode related to the blue color of LED22 (blue cathode terminal) is connected to the collector terminal of NPN transistor 703 via one resistor (R78).

[0117] One end side of each block is connected to the 24V power line. Specifically, the wiring (lines) related to red, green, and blue in each block are connected to the 24V power line.

[0118] On the other end side of each block, the wiring related to green in each block (a total of 5 lines) merges, and one line is connected to the collector terminal of one NPN transistor 702.

[0119] On the other end side of each block, the wiring related to blue in each block (a total of 5 lines) merges, and one line is connected to the collector terminal of one NPN transistor 703.

[0120] On the other end side of each block, the wiring related to red in each block is such that the wiring of three blocks (3 lines) merges, and one line is connected to the collector terminal of one NPN transistor 701a, and the wiring of two blocks (2 lines) merges, and one line is connected to the collector terminal of one NPN transistor 701b.

[0121] The maximum output current value (the upper limit of the current that can flow) of the NPN transistor according to this embodiment is 50 mA, and the current value (about 52 mA) related to the red lines (total of 5) is larger than the maximum output current value of the NPN transistor. Therefore, for the red lines, they are divided into two systems without merging the five wirings (divided into a line where three are merged and a line where two are merged as described above). In other words, the circuit connected to the collector terminal of one NPN transistor 701a is in three parallel, and the circuit connected to the collector terminal of the other NPN transistor 701b is in two parallel. As a result, the current values input to the NPN transistor 701a and the NPN transistor 701b are each 50 mA or less. Specifically, the current value input to the NPN transistor 701a is 31.2 mA (<50 mA), and the current value input to the NPN transistor 701b is 20.8 mA (<50 mA).

[0122] The output terminals (PO1 to PO3) of the driver IC620a are directly connected to the base terminals of the NPN transistors. When the output terminals are set to High (voltage level High) (when a High control signal is output), a current (base current) flows from the base to the emitter of the NPN transistors 701a, 701b, 702, 703, and a current (collector current) flows from the collector to the emitter (each NPN transistor becomes in the ON state), and 26 LEDs may be configured to emit light. In this case, when the driver IC620a sets the output terminals to Low (voltage level Low) (when a Low control signal is output), each NPN transistor becomes in the OFF state and the LEDs do not emit light. In this embodiment, the NPN transistor performs switching to turn ON and OFF according to the control signal, and can be called a "switching circuit that performs switching according to the control signal".

[0123] In this embodiment, the driver IC620a is configured to cause the LED to emit light when the terminal voltages of the output terminals (PO1 to PO3) are set to Low (when a Low control signal is output). Therefore, when an NPN transistor is connected between the output terminal and the LED, the logic is inverted, and the LED does not emit light when an attempt is made to cause it to emit light. Thus, in this embodiment, a PNP transistor is connected between the output terminal of the driver IC620a and the NPN transistor, forming a two-stage configuration of an NPN transistor and a PNP transistor.

[0124] The PNP transistors include a PNP transistor 801 related to red light emission, a PNP transistor 802 related to green light emission, and a PNP transistor 803 related to blue light emission. The emitter terminal of each PNP transistor is connected to the 5V power supply line. Note that the maximum output current value (the upper limit of the current that can flow) of the PNP transistors according to this embodiment is 30 mA.

[0125] The base terminal of the PNP transistor 801 is connected to the first output terminal PO1. The collector terminal of the PNP transistor 801 is connected to the base terminals of an NPN transistor 701a and an NPN transistor 701b. The output of the PNP transistor 801 is branched into two, with one output input to the base terminal of one NPN transistor 701a and the other output input to the base terminal of the other NPN transistor 701b.

[0126] The base terminal of the PNP transistor 802 is connected to the second output terminal PO2. The collector terminal of the PNP transistor 802 is connected to the base terminal of an NPN transistor 702.

[0127] The base terminal of the PNP transistor 803 is connected to the third output terminal PO3. The collector terminal of the PNP transistor 803 is connected to the base terminal of an NPN transistor 703.

[0128] When the driver IC620a sets the terminal voltages of the output terminals (PO1 to PO3) to Low (when outputting a Low control signal), a current (base current) flows from the emitters to the bases of the PNP transistors 801, 802, and 803, and a current (collector current) flows from the emitters to the collectors (each PNP transistor is in the ON state). Based on this, the NPN transistors 701a, 701b, 702, and 703 are in the ON state, and 26 LEDs emit light. When the driver IC620a sets the output terminals (PO1 to PO3) to High (when outputting a High control signal), the PNP transistors 801, 802, and 803 are in the OFF state, and the LEDs do not emit light. When connecting PNP transistors as in this embodiment, it is possible to suppress the voltage of the output terminals (PO1 to PO3) from becoming a high voltage.

[0129] Here, block C is defined as the "first block" and block D is defined as the "second block". The NPN transistors (switching circuits) connected to the line related to red (a specific color) in the first block and the line related to red (the specific color) in the second block are different. On the other hand, the NPN transistors (switching circuits) connected to the line related to a predetermined color (green or blue) in the first block and the line related to the predetermined color (green or blue) in the second block are the same. In this embodiment, when considering all the blocks in which the driver IC620a controls light emission, the number (M: 2 in this embodiment) of NPN transistors (switching circuits) connected to the line related to red (a specific color) is larger than the number (N: 1 in this embodiment) of NPN transistors (switching circuits) connected to the line related to a predetermined color (green or blue).

[0130] As described above, for the line related to red (a specific color), the current value required for the LED to light is relatively large, and the number of NPN transistors connected is larger than that for the line related to a predetermined color (green or blue). For red, if the number of NPN transistors is the same as that for green or blue (1), as described above, the current required for lighting cannot flow through the NPN transistor. In this embodiment, by relatively increasing the number of NPN transistors connected to the line related to red, the LED can be lit in red.

[0131] In this embodiment, 26 LEDs are divided into 5 systems (5 blocks), 4 of which have 5 LEDs each and 1 has 6 LEDs, but the number of LEDs in each system is not limited to this. For example, 4 of the 5 systems may have 6 LEDs each and 1 may have 2 LEDs. However, when configured as in this embodiment (Fig. 11), it is possible to suppress the variety of types of limiting resistors to be specified and use more of the same type of resistor. In block C, the cathode related to the red of LED 11 (red cathode terminal) is connected to the collector terminal of NPN transistor 701a via two resistors (R65, R66). Compared with the red lines of other blocks, only one 200Ω resistor is removed, and the remaining two resistors are common to the red lines of other blocks.

[0132] The gaming machine of this embodiment includes a substrate (lower panel middle slave LED substrate 620) on which a plurality of full-color LEDs and a control IC (driver IC620a) capable of outputting a control signal for controlling the light emission of the full-color LEDs are arranged. The full-color LED can emit light in a specific color and a predetermined color other than the specific color. When a unit formed by connecting a predetermined number of the full-color LEDs in series is defined as a block, the plurality of blocks are connected in parallel to each other. One end side of the block is connected to a power line. A switching circuit (NPN transistors 701a, 701b, 703) that performs switching according to the control signal is connected between the other end side of the block and the output terminal. The plurality of blocks include a first block (block C) and a second block (block D). Different switching circuits (NPN transistors 701a, 701b) are connected to the line related to the specific color (red) in the first block and the line related to the specific color in the second block, respectively. The same switching circuit (NPN transistor 703) is connected to the line related to the predetermined color (blue) in the first block and the line related to the predetermined color in the second block. The number of switching circuits connected to the line related to the specific color is larger than the number of switching circuits connected to the line related to the predetermined color.

[0133] With the output of one control IC, a large number of LEDs that require a predetermined current value exceeding the maximum value of the output of the control IC (for example, 30 mA) for light emission can be lit. In other words, with one control IC, a larger number of LEDs can be lit. Thereby, the number of control ICs arranged on the substrate can be reduced.

[0134] Also, in the gaming machine of this embodiment, The current value required to cause the LED to emit light in the specific color is larger than the current value required to cause the LED to emit light in the predetermined color.

[0135] The invention according to this embodiment can be applied to, for example, a substrate that irradiates light to the lower panel or the like of a gaming machine (slot machine), and is a substrate that causes a large number of LEDs to emit light in the same emission color.

[0136] In this embodiment, a two-stage configuration of an NPN transistor and a PNP transistor is adopted. However, when the number of LEDs to be lit is small, it may be configured using only a PNP transistor without using an NPN transistor. For example, connect the line where the lines related to red in each block converge to the emitter terminal of a PNP transistor 801, connect the line where the lines related to green in each block converge to the emitter terminal of a PNP transistor 802, connect the line where the lines related to green in each block converge to the emitter terminal of a PNP transistor 803, and connect the collector terminals of each PNP transistor to the ground. In this case, when the output terminals (PO1 to PO3) are set to Low, the LEDs can be made to emit light, and the logic does not invert. Regarding the lines related to red, for example, they may be divided into 3 parallel lines and 2 parallel lines, and each may be configured to be connected to the emitter terminals of separate PNP transistors.

[0137] Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist thereof. Also, within the scope of the present invention, a free combination of each embodiment, or a modification of any component of each embodiment, or an omission of any component in each embodiment is possible. For example, the configuration of a slot machine and the like is not limited to that of the above-described embodiments.

[0138] In addition, the above-described configuration and the like are not limited to slot machines, and can also be applied to other gaming machines such as pachinko machines and medal-less gaming machines. The present invention can be applied to gaming machines, and gaming machines include slot machines, pachinko machines, and medal-less gaming machines (management slot machines having a structure in which a player can play a game without using gaming medals).
