[0032] The power supply unit 10 includes a power supply board. The power supply board creates a DC power supply (for example, 12V, 24V, etc.) from power sent from outside the gaming machine via a power cable, and supplies the power to each board of the gaming machine. The supply of power from the power supply board 10A will be described with reference to FIG. 4. The power supply board 10A receives power from the outside and generates DC (direct current) 24V power. The power supply board 10A also generates DC 12V from DC 24V power. The power supply board 10A may also generate DC 5V or DC 37V. The power supply board 10A can supply a part or all of the generated power to the boards in the gaming machine. The supply of power from the outside of the gaming machine may be a commercial AC (alternating current) 100V power supply or a AC 24V power supply.

[0033] The power supply board 10A supplies DC 24V and DC 12V power to the sub-control board 90. A relay board (not shown) may be provided to relay 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 3.3V power from the DC 12V power received from the power supply board 10A (relay board), and supplies the power to the logic circuit in the sub-control board 90.

[0034] Although not shown in the figures, the sub-control board 90 may generate DC 5V power from DC 12V power and supply power to the logic circuitry within the sub-control board 90.

The sub-control board 90 also includes a control ROM 301, a crystal oscillator 302, a RAM 303, and a watchdog timer IC 304. The control ROM 301 stores a program related to performance control. The CPU 300 accesses the control ROM 301 via the CPU bus and controls the performance by executing the program stored in the control ROM 301. The watchdog timer IC 304 is connected to a reset terminal of the CPU 300, and outputs a reset signal to the CPU 300 when a predetermined condition is met (for example, when it detects that the voltage is unstable). The RAM 303 is a storage area for backup data. The crystal oscillator 302 generates a clock signal of a predetermined frequency.

[0037] The effect determination unit of the CPU 300 determines the content of the effect to be executed based on various commands sent from the main control board 80, input signals from the effect buttons 36, etc. In addition, the display control unit, sound control unit, lamp control unit, and motor control unit of the CPU 300 control the execution of the effect determined by the effect determination unit.

[0038] (image) The VDP305 is a processor that performs image processing (drawing processing) related to the display of images (video) on the liquid crystal display according to commands from the display control unit, and is integrated with the CPU300 on a single chip. The VDP305 has a built-in VRAM and decoder. The display control unit controls the VDP305 based on the determined performance content, and controls the display on the liquid crystal display. The display control unit executes liquid crystal drawing processing at a predetermined cycle (for example, at a frame rate of 60 times per second = 60 FPS). In the liquid crystal drawing processing, it constructs a command (information) that instructs the VDP305 on the drawing content. Based on the command, the VDP305 reads out the necessary drawing material from the image / audio ROM310 and performs drawing (generates image data showing one frame of frame image on the frame buffer), generates a liquid crystal signal, and outputs it to the liquid crystal board. A liquid crystal signal is composed 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).

[0039] The liquid crystal substrate is equipped with a signal conversion circuit (signal conversion means), which generates a driving signal to be sent 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, 60 frames of images (still images) are displayed per second, and a moving image is displayed. Note that one frame may also be referred to as a "frame." For example, in the case of a performance image (performance pattern) with a performance time of 60 seconds, the performance image is composed of 60 seconds x 60 frames, for a total of 3,600 frames.

[0040] (audio) The audio IC 306 controls the output of audio from the speaker according to a command from the audio control unit. The audio IC 306 is integrated with the CPU 300 on one chip.

The audio control unit controls the audio IC 306 based on the determined performance content, and controls the output of audio from the speaker. The audio control unit transmits a command to the audio IC 306 to instruct the audio to be output. Based on the command, the audio IC 306 reads out the necessary audio material from the image / audio ROM 310, generates an audio signal, and outputs it. The amplifier 307 has a function of converting the signal input from the audio 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 (audio signal) sent from the audio IC 306, and outputs sound from the speaker. The audio IC 306 can control the output volume from the speaker based on an input signal from a volume adjustment switch 95, which will be described later.

[0041] In this embodiment, the amplifier 307 is disposed on the sub-control board 90, but this is not limiting, and the amplifier 307 may be disposed on a board different from the sub-control board 90.

[0042] (lamp) The lamp control unit controls the lighting patterns (including color and brightness) of various lights (lamps) provided in the slot machine 100. The lamp control unit generates a command (lighting control signal) based on the determined performance content, and outputs it to the driver IC of the illumination board. The illumination board is a board that controls the lighting (light emission) of various lamps (LEDs). The driver IC controls the voltage applied to the lamps (LEDs) based on the input lighting control signal. The lighting of the lamps is controlled via the driver IC of the illumination board. The lighting control signal is a serial signal. The lamp control unit may be provided integrally with the CPU 300, or may be provided separately from the CPU 300.

[0043] (Movable parts) In this embodiment, a movable prop performance can be performed at the front door 20, in which a movable prop (movable body) moves at a predetermined trigger. The motor control unit controls the operation of the motor that serves as the driving source for the movable prop. The motor control unit generates a command (motor control signal) based on the determined performance content, and outputs it to the driver IC of the movable prop control board. The movable prop control board is a board that controls the operation of the motor. The driver IC controls the voltage applied to the motor based on the input motor control signal. The motor operation is controlled via the driver IC of the movable prop control board. The motor control unit may be provided integrally with the CPU 300, or may be provided separately from the CPU 300.

[0044] In the above description, the motor control unit controls the operation of the motor that drives the movable props, but the motor control unit may also control the operation of the motor that drives the performance button 36. In other words, the performance button 36 may be configured to execute a performance in which it vibrates at a predetermined trigger, and the motor control unit may control the operation of the motor that vibrates the performance button 36.

[0049] The component side of the sub-control board 90 is provided with a wiring pattern (signal line L2) that connects the terminals (through holes corresponding to the terminals) of the CPU 300 and the terminals (through holes corresponding to the terminals) of the second connector 93. The CPU 300 can output a lighting control signal (second signal) to the illumination board via the signal line L2 (and the second connector 93). The lighting control signal can be said to be a signal related to the lighting of the lights (a signal related to the execution of the performance).

[0050] Here, if the signal line L1 and the signal line L2 are regarded as the first signal line, the first signal line can be said to be a signal related to the execution of a performance output by the CPU 300. Note that the term "first signal line" does not necessarily refer to both the signal line L1 and the signal line L2, but may refer to at least one of the signal line L1 and the signal line L2.

[0051] A first switch 95 is mounted on the outer periphery of the component surface of the sub-control board 90, near a second side opposite to the first side. The first switch 95 is a rotary switch, and the knob can be rotated to set the level (setting value) to one of a plurality of levels. The first switch 95 is a switch (volume adjustment switch) for adjusting the volume of the sound output from the speaker. The component surface of the sub-control board 90 is provided with a wiring pattern (signal line L3) that connects the terminal of the CPU 300 (a through hole corresponding to the terminal) and the terminal of the first switch 95 (a through hole corresponding to the terminal). The CPU 300 can receive a signal (a third signal) related to the operation of the first switch 95 via the signal line L3.

[0052] Also, a second switch 96 is mounted on the outer periphery of the component surface of the sub-control board 90, near a second side opposite to the first side. The second switch 96 is a momentary switch that can be pressed down. The second switch 96 is, for example, a switch (reset switch) for resetting the performance. A wiring pattern (signal line L4) is provided on the component surface of the sub-control board 90, connecting a terminal (a through hole corresponding to the terminal) of the CPU 300 and a terminal (a through hole corresponding to the terminal) of the second switch 96. The CPU 300 can receive a signal (fourth signal) related to the operation of the second switch 96 via the signal line L4.

[0053] The signal lines L3 and L4 may be referred to as second signal lines. The term "second signal line" does not necessarily refer to both the signal lines L3 and L4, but may refer to at least one of the signal lines L3 and L4.

[0054] In addition, in FIG. 6, signal line L1, signal line L2, signal line L3 and signal line L4 are all provided (routed) on the component surface (surface layer), but at least a portion of signal line L1, signal line L2, signal line L3 and signal line L4 may be provided on another layer (back surface layer) of the sub-control board 90.

[0055] The sub-control board 90 has a function of relaying the power supplied from the power supply board 10A to other boards, etc. The sub-control board 90 is a multi-layer board. In this embodiment, the sub-control board 90 is configured to include a front layer (component surface, signal layer) as an outer layer, a power supply layer as an inner layer, and a back layer (component surface, signal layer) as an outer layer.

[0056] Fig. 7 is a schematic diagram of the power supply layer viewed from the direction facing the power supply layer (the same direction as Fig. 6). The sub-control board 90 has wiring (patterns) on the inner layer of the board for transmitting power (power) supplied from the power supply board 10A. The power supply layer is provided with wiring (patterns) for not only the power supplied from the power supply board 10A, but also the power (3.3V) generated by the sub-control board 90. Hereinafter, the pattern for transmitting power in the power supply layer is referred to as the power supply pattern. The power supply pattern can be referred to as the power line, power wire, power supply path, etc.

[0057] The power supply layer is provided with a 24V power supply pattern V1 (solid power supply pattern), a 12V power supply pattern V2 (solid power supply pattern), a 3.3V power supply pattern V3 (solid power supply pattern), and a ground pattern V0 (solid ground).

[0058] By providing the power supply pattern on the power supply layer (concentrating it on an inner layer) rather than on the same layer (e.g., the surface layer) as the signal line (e.g., signal line L1) is provided, the area of ​​the solid ground on the surface layer (other layer) can be made larger. This reduces the effect of noise on the signal transmitted by the signal line. Also, by using an inner layer, the area of ​​the power supply pattern (solid power supply pattern) can be made larger.

[0059] In the power supply layer, a low voltage (low current) power supply pattern is provided on the inside (the center of the board), and a high voltage (high current) power supply pattern is provided on the outside (the outer periphery of the board). It can be said that there is no high voltage (12V, 24V) power supply pattern in the center of the power supply layer.

[0060] FIG. 8 is a schematic diagram in which a surface layer (first layer) and a power layer (second layer) are superimposed, with the surface layer being displayed transparently. Hereinafter, the thickness direction (direction perpendicular to the paper surface) of the plate-shaped sub-control board 90 will be referred to as the "thickness direction of the board". The thickness direction of the board can be rephrased as the stacking direction of the boards. Also, one surface of the outer layer of the sub-control board 90 will be referred to as the board surface, and the thickness direction of the board will sometimes be referred to as the direction perpendicular to the board surface of the sub-control board 90.

[0061] The CPU 300 is disposed at a position overlapping the 3.3V power supply pattern V3 (at a position corresponding to the power supply pattern V3) when viewed in a direction perpendicular to the board surface of the sub-control board 90 (in the thickness direction of the board). The first connector 92 and the second connector 93 are positioned at a position overlapping with the 12V power supply pattern V2 (a position corresponding to the power supply pattern V2) when viewed in a direction perpendicular to the board surface of the sub-control board 90 (in the thickness direction of the board). When viewed from a direction perpendicular to the board surface of the sub-control board 90, the signal line L1 overlaps with the power supply pattern V3 and the power supply pattern V2, but does not overlap with the power supply pattern V1. When viewed from a direction perpendicular to the board surface of the sub-control board 90, the signal line L2 overlaps with the power supply pattern V3 and the power supply pattern V2, but does not overlap with the power supply pattern V1.

[0062] The power (24V) transmitted by the power supply pattern V1 (specific power supply pattern) is power supplied to the amplifier 307 that drives the speaker and the motor that drives a specific performance device (movable props or performance button 36). The power supply pattern V1 has a relatively large load fluctuation (a relatively large current flows), so it is prone to generating noise (easily radiating noise) due to voltage fluctuations (up and down). In other words, the power supply pattern V1 of the power supply layer is prone to becoming a source of noise.

[0063] The first and second signals are signals (digital signals) whose waveforms go up and down repeatedly. The signal lines L1 and L2 can be said to be transmission paths (signal transmission paths) for digital signals. On the other hand, the third and fourth signals are signals related to the output of the switch, and are signals that indicate a certain value (for example, High or Low). Therefore, the first and second signals are more susceptible to noise than the switch-based signals (the third and fourth signals). Even if the third and fourth signals are affected by noise, processing based on the reception of the signals can be properly performed. In contrast, when the first and second signals are affected by noise, there is a relatively high possibility that processing based on the reception of the signals will not be performed correctly. The first and second signals (high-speed signals that are easily affected by noise) can be said to be important signals because problems such as processing based on the reception of the signals not being performed correctly (including malfunction) can occur when the signals are affected by noise (when the signal waveform is disturbed).

[0064] In this embodiment, the signal line L1 through which the first signal is transmitted and the signal line L2 through which the second signal is transmitted are routed (wired) in a position (range) that does not overlap with the 24V power supply pattern V1 (noise source) when viewed from a direction perpendicular to the board surface of the sub-control board 90 (in the thickness direction of the board). In other words, the signal line L1 and the signal line L2 are not provided in a range that overlaps with the power supply pattern V1 when viewed from a direction perpendicular to the board surface of the sub-control board 90.

[0065] The distance between the signal line L1 and the 24V power supply pattern V1 and the distance between the signal line L2 and the power supply pattern V1 are relatively large. In other words, the signal line L1 and the signal line L2 are kept away from the 24V power supply pattern V1. Therefore, even if noise occurs in the 24V power supply pattern V1 of the power supply layer, the first signal and the second signal are less susceptible to the influence of the noise. In other words, the influence of noise on the first signal and the second signal can be reduced.

[0066] The power (12V) transmitted by the power supply pattern V2 of the power supply layer is supplied to, for example, lighting (LED), but lighting has smaller load fluctuations than speakers and motors. Therefore, the power supply pattern V2 is less likely to be a source of noise than the power supply pattern V1. Therefore, it is permissible to provide at least a part of the signal line L1 and the signal line L2 at a position overlapping the 12V power supply pattern V2 when viewed from a direction perpendicular to the board surface of the sub-control board 90. However, it is more preferable that the signal line L1 and the signal line L2 are not provided at a position overlapping the 12V power supply pattern V2.

[0067] Although not shown in the figure, a watchdog timer IC304 is disposed near the CPU300. The watchdog timer IC304 is disposed in a position (range) overlapping with the 3.3V power supply pattern V3 when viewed from a direction perpendicular to the board surface of the sub-control board 90 (in the thickness direction of the board). If a wiring pattern connecting the reset terminal (corresponding through hole) of the CPU300 and the terminal (corresponding through hole) of the watchdog timer IC304 is a signal line L5 (not shown), the signal line L5 is routed in a position not overlapping with the 24V power supply pattern V1 when viewed from a direction perpendicular to the board surface of the sub-control board 90. When viewed from a direction perpendicular to the board surface of the sub-control board 90, the signal line L5 is provided in a position overlapping with the 3.3V power supply pattern V3. The reset signal (fifth signal) is an important signal that has a relatively large influence when not transmitted correctly, so the signal line L5 is routed in a position not overlapping with the 24V power supply pattern V1. Therefore, even if noise occurs in the 24V power supply pattern V1, the fifth signal is less susceptible to the influence of the noise. In other words, the influence of noise on the fifth signal can be reduced.

[0068] On the other hand, the first switch 95 and the second switch 96 are arranged at positions overlapping the 24V power supply pattern V1 when viewed from a direction perpendicular to the board surface of the sub-control board 90 (in the thickness direction of the board). At least a part of the signal line L3 and the signal line L4 is provided at a position overlapping the 24V power supply pattern V1 when viewed from a direction perpendicular to the board surface of the sub-control board 90 (in the thickness direction of the board). As described above, even if the third signal and the fourth signal are affected by noise, processing based on the reception of the signal can be appropriately performed, so that at least a part of the signal line L3 and the signal line L4 is allowed to overlap the 24V power supply pattern V1. By providing at least a part of a predetermined switch (the first switch 95 or the second switch 96) or a signal line (the signal line L3 or the signal line L4) at a position overlapping the 24V power supply pattern V1 and utilizing the space, the freedom of board design can be further improved.

[0069] In this embodiment, the sub-control board 90 (specific board) has been used for explanation, but the above-mentioned configuration may be adopted not only in the sub-control board 90 but also in other boards (e.g., relay boards) provided in the gaming machine, and the effect of noise on a specified signal may be reduced.

[0070] The gaming machine of this embodiment is A specific board (sub-control board 90) on which a control means (CPU 300) for controlling the execution of the performance is arranged; A power supply board (power supply board 10A) capable of supplying power to the specific board, The specific substrate comprises an outer layer and an inner layer, The outer layer is provided with a first signal line (signal line L1 or signal line L2) for transmitting a signal related to the execution of the performance output by the control means, a power supply pattern for transmitting power supplied from the power supply board is provided on the inner layer; The power supply patterns include a specific power supply pattern (power supply pattern V1) capable of supplying power to an amplifier (amplifier 307) that drives a speaker, The first signal line is provided at a position that does not overlap the specific power supply pattern in the thickness direction of the specific substrate.

[0071] In addition, the gaming machine of this embodiment has A specific board (sub-control board 90) on which a control means (CPU 300) for controlling the execution of the performance is arranged; A power supply board (power supply board 10A) capable of supplying power to the specific board, The specific substrate comprises an outer layer and an inner layer, The outer layer is provided with a first signal line (signal line L1 or signal line L2) for transmitting a signal related to the execution of the performance output by the control means, a power supply pattern for transmitting power supplied from the power supply board is provided on the inner layer; The power supply pattern includes a specific power supply pattern (power supply pattern V1) capable of supplying power to a motor that drives a predetermined performance device (movable prop or performance button 36), The first signal line is provided at a position that does not overlap the specific power supply pattern in the thickness direction of the specific substrate.

[0072] The specific power supply pattern transmits power supplied to an amplifier (or motor) and is susceptible to becoming a source of noise since the load fluctuates greatly. In this embodiment, the first signal line is provided at a position that does not overlap with the specific power supply pattern in the thickness direction of the specific board. This makes it possible to reduce the influence of noise generated in the specific power supply pattern (disturbance of the signal) on the signal (signal related to the execution of the performance) passing through the first signal line. In other words, it is possible to reduce the influence of noise on the signal.

[0073] In addition, in the gaming machine of this embodiment, A predetermined switch (first switch 95 or second switch 96) is arranged on the specific board, A second signal line (signal line L3 or signal line L4) connecting the predetermined switch and the control means is provided on the outer layer, At least a portion of the second signal line is provided at a position overlapping the specific power supply pattern in a thickness direction of the specific substrate.

[0074] By providing at least a part of the second signal line at a position overlapping the specific power supply pattern and making effective use of space, the degree of freedom in board design can be further improved.

[0075] (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 of the first embodiment. Therefore, the description of the same configuration as the first embodiment will be omitted or simplified.

[0076] 9 is a schematic diagram of the sub-control board 90 according to this embodiment, viewed from the direction facing the surface layer (component surface, board surface). The sub-control board 90 is a multi-layer board. In this embodiment, the sub-control board 90 is configured to include a surface layer (component surface, signal layer) as an outer layer, a power supply layer as an inner layer, and a back layer (component surface, signal layer) as an outer layer.

[0077] On the surface layer (component surface) of the sub-control board 90, there are arranged, as main electronic components, a CPU 300, a control ROM 301, a RAM 303, a first amplifier 307a, a second amplifier 307b, a power supply IC 311 (regulator), a power supply IC 312 (regulator), a power supply IC 313 (regulator), a backup capacitor 314, a first connector CN1, a second connector CN2, etc. The sub-control board 90 is supplied with power (power from upstream) from the power supply board 10A (FIG. 4) via the first connector CN1. Specifically, power of a first high voltage (18V), power of a second high voltage (24V), and power of a third high voltage (12V) are supplied. In addition, the sub-control board 90 outputs (supplies downstream) the power of the first high voltage (18V), power of the second high voltage (24V), and power of the third high voltage (12V) via the second connector CN2. The sub-control board 90 has a function of relaying the first high voltage power, the second high voltage power, and the third high voltage power supplied from the power supply board 10A.

[0078] When a power supply pattern (solid power supply pattern) for transmitting a first high voltage power, a power supply pattern (solid power supply pattern) for transmitting a second high voltage power, and a power supply pattern (solid power supply pattern) for transmitting a third high voltage power are provided on the surface layer (component surface) of the sub-control board 90, the power supply pattern for transmitting high voltage power is more likely to generate noise than the power supply pattern for transmitting low voltage power, so it is considered to provide it away from the CPU 300 and on the outer periphery of the board. However, in that case, providing the power supply pattern for transmitting high voltage power on the outer periphery of the board causes a problem that the arrangement of components on the outer periphery is restricted. Therefore, in this embodiment, a layer (power supply layer) dedicated to the power supply is provided on the inner layer of the sub-control board 90, and the wiring (power supply pattern) of the power supply (power supplied from the power supply board 10A) is routed on the power supply layer, thereby avoiding the occurrence of such a problem.

[0079] Fig. 10 is a schematic diagram of the power supply layer of the sub-control board 90, viewed from the direction directly opposite the power supply layer (the same direction as Fig. 9). In the power supply layer, a first high voltage power supply pattern, a second high voltage power supply pattern, and a third high voltage power supply pattern are provided on the outer periphery of the board (routed along the outer periphery of the board).

[0080] FIG. 11 is a schematic diagram in which a surface layer (first layer) is overlaid on a power supply layer (second layer) and the surface layer is made to have a transmissive display. The surface layer (component surface) is provided with a first specific wiring P1 electrically connected to a first high voltage (18V) power supply pattern of the power supply layer via a through hole (via hole). The first specific wiring P1 extends from the outside to the inside of the board and is connected to (a terminal of) a power supply IC 311. The power supply IC 311 generates a first low voltage (e.g., 3.3V) power from the first high voltage (18V) power. The generated first low voltage power is supplied to the power supply layer via a through hole (via hole). A first low voltage power supply pattern is provided in the center of the power supply layer (FIG. 10).

[0081] The surface layer is provided with a second specific wiring P2 electrically connected to the power supply pattern of the third high voltage (12 V) of the power supply layer via a through hole (via hole). The second specific wiring P2 extends from the outside to the inside of the substrate and is connected to (the terminal of) the power supply IC 312. The power supply IC 312 generates a second low voltage (e.g., 1.05 V) from the third high voltage (12 V) power. The generated second low voltage power is supplied to the power supply layer via the through hole (via hole). The second low voltage power pattern is provided in the center of the power supply layer (FIG. 10).

[0082] The surface layer is provided with a third specific wiring P3 electrically connected to the power supply pattern of the third high voltage (12 V) of the power supply layer via a through hole (via hole). The third specific wiring P3 extends from the outside to the inside of the substrate and is connected to (the terminal of) the power supply IC 313. The power supply IC 313 generates a third low voltage (e.g., 1.2 V) from the third high voltage (12 V) power. The generated third low voltage power is supplied to the power supply layer via the through hole (via hole). A third low voltage power supply pattern is provided in the center of the power supply layer (FIG. 10).

[0083] The surface layer is provided with a fourth specific wiring P4 electrically connected to the power supply pattern of the third high voltage (12V) of the power supply layer via a through hole (via hole). The fourth specific wiring P4 extends from the outside to the inside of the board and is connected to (the terminal of) the backup capacitor 314. The backup capacitor 314 functions as a power storage device. When the supply of power to the sub-control board 90 is cut off (during a power outage), the backup capacitor 314 supplies power (backup power supply) to the RAM 303. This allows the data stored in the RAM 303 to be retained.

[0084] The surface layer is provided with a first amplifier 307a and a second amplifier 307b. The surface layer is also provided with a fifth specific wiring P5 and a sixth specific wiring P6 electrically connected to the second high voltage (24V) power supply pattern of the power supply layer via a through hole (via hole). The fifth specific wiring P5 extends from the outside to the inside of the substrate and is connected to (the terminal of) the first amplifier 307a. The sixth specific wiring P6 extends from the outside to the inside of the substrate and is connected to (the terminal of) the second amplifier 307b. The first amplifier 307a and the second amplifier 307b drive the speaker based on a signal (audio signal) sent from the audio IC 306, causing the speaker to output sound.

[0085] On the surface layer, a CPU 300 is disposed in the center, and many signal lines related to important signals are provided around the CPU 300.

[0086] A first low-voltage power supply pattern, a second low-voltage power supply pattern, and a third low-voltage power supply pattern are provided at the center of the power supply layer (FIG. 10). It can be said that the low-voltage power supply patterns are provided at positions overlapping with the CPU 300 in the thickness direction of the board. The CPU 300 is supplied with low-voltage power generated by the sub-control board 90. The low-voltage power supply patterns in the power supply layer are less likely to generate noise than the high-voltage power supply patterns. The low-voltage power supply patterns are less likely to affect signals transmitted through signal lines provided at positions overlapping with them in the thickness direction of the board.

[0087] No high-voltage power supply pattern is provided at a position overlapping with the CPU 300 in the thickness direction of the board. As shown in FIG. 10, the first high-voltage power supply pattern, the second high-voltage power supply pattern, and the third high-voltage power supply pattern are provided on the outer periphery (along the periphery) in the power supply layer. The high-voltage power supply patterns are highly likely to generate noise and affect peripheral signals (signals transmitted through signal lines). By providing the high-voltage power supply patterns on the outer periphery of the power supply layer, it is possible to suppress the high-voltage power supply patterns from affecting signals transmitted through signal lines provided on the central side of the outer layer (front surface layer or back surface layer).

[0088] On the surface layer, components to which high-voltage power is supplied include power supply IC 311 to power supply IC 313, backup capacitor 314, first amplifier 307a, and second amplifier 307b. If the components to which high-voltage power is supplied are arranged on the outer periphery (along the periphery), there is a possibility that they may interfere with surrounding components (for example, a case covering sub-control board 90). Therefore, the components to which high-voltage power is supplied are arranged on the inside rather than along the periphery, but are arranged outside the arrangement position of CPU 300.

[0089] The surface layer is provided with first specific wiring P1 to sixth specific wiring P6 as wiring for connecting (electrically connecting) components to which high-voltage power is supplied (power supply IC 311 to power supply IC 313, backup capacitor 314, first amplifier 307a, and second amplifier 307b) with the high-voltage power supply pattern of the power supply layer. The first specific wiring P1 to sixth specific wiring P6 extend from the outside to the inside of the board. Note that, although the first specific wiring P1 to sixth specific wiring P6 are shown as straight lines in FIG. 11, the first specific wiring P1 to sixth specific wiring P6 may have bent portions. The width of each of the first specific wiring P1 to sixth specific wiring P6 is smaller than the width of the power supply pattern (solid power supply pattern) in the power supply layer.

[0090] The wiring related to the high voltage in the surface layer is likely to radiate noise and affect the signals transmitted by the surrounding signal lines. In this embodiment, a high-voltage power supply pattern is provided in the power supply layer (on the outer periphery of the power supply layer), and the surface layer is provided with minimum wiring (first specific wiring P1 to sixth specific wiring P6). In this embodiment, high-voltage power supply patterns with large pattern widths (first high-voltage power supply pattern (solid pattern), second high-voltage power supply pattern (solid pattern), and third high-voltage power supply pattern (solid pattern)) are not provided on the outer periphery of the surface layer, and these power supply patterns are provided in the inner layer (power supply layer), and the surface layer is provided with the minimum necessary (narrow width) patterns from these power supply patterns (first specific wiring P1 to sixth specific wiring P6).

[0091] This makes it possible to prevent the power lines related to high voltage from affecting signals transmitted through peripheral signal lines (particularly the signal lines related to the CPU 300) on the surface layer. Also, it is possible to prevent wiring (power lines related to high voltage) that may be a source of noise from passing near the signal lines (signal lines for important signals) related to the CPU 300 provided on the central side of the board.

[0092] In this embodiment, the sub-control board 90 (specific board) has been used for explanation, but the above-mentioned configuration may be adopted not only in the sub-control board 90 but also in other boards (e.g., relay boards) provided in the gaming machine, and the effect of noise on a specified signal may be reduced.

[0093] The gaming machine of this embodiment is A specific board (sub-control board 90) on which a specific component (e.g., a power supply IC 311) is arranged, A power supply board (power supply board 10A) capable of supplying power to the specific board, The specific substrate comprises a first layer and a second layer, a power supply pattern for transmitting power of a predetermined voltage supplied from the power supply board is provided on the outer periphery of the second layer; The first layer has a specific wiring (e.g., specific wiring P1) that is electrically connected to the power supply pattern of the second layer and supplies the power to the specific component, the specific wiring extending from the outside to the inside.

[0094] Wiring that transmits power of a specific voltage supplied from a power supply board is likely to be a source of noise. In this embodiment, the power supply pattern is provided on the outer periphery of the second layer, and the specific wiring from the power supply pattern in the first layer is configured to extend from the outside to the inside, so that the number of wirings that transmit power of the specific voltage in the first layer is relatively small (the area of ​​the wiring is reduced). With this configuration, it is possible to suppress the influence of noise on signals transmitted by signal lines provided on the center side of the first layer. In other words, it is possible to reduce the influence of noise on signals.

[0095] In addition, in the gaming machine of this embodiment, The predetermined component generates power having a voltage lower than the predetermined voltage from power having the predetermined voltage, and therefore the power having a voltage lower than the predetermined voltage generated by the predetermined component can be supplied to a component disposed on the central side of the first layer.

[0096] The present invention is not limited to the above-described embodiment, and can be modified in various ways without departing from the spirit of the present invention. Furthermore, the present invention allows free combination of the embodiments, modification of any of the components of the embodiments, or omission of any of the components of the embodiments, within the scope of the invention. For example, the configuration of the slot machine is not limited to that of the above-described embodiment.

[0097] In addition, the above-mentioned configuration can be applied not only to slot machines but also to other gaming machines such as pachinko gaming machines and medal-less gaming machines. The present invention can be applied to gaming machines, which include slot machines, pachinko gaming machines, and medal-less gaming machines (managed slot machines structured so that players can play without using gaming medals).
