The counter timer 512 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 404 at each interrupt time. The CPU 504 controls each IC and each circuit based on the interrupt request timing.

  The second sub-control unit 500 is provided with a sound source IC 513 and the sound source IC 513 is provided with speakers 272 and 277. The sound source IC 513 controls sound output from the amplifier (the amplifier 53 in FIG. 7) and the speakers 272 and 277 in accordance with a command from the CPU 504. The sound source IC 513 is connected to an S-ROM (sound ROM) in which audio data is stored. The audio data acquired from the ROM is amplified by an amplifier and output from the speakers 272 and 277.

  The second sub-control unit 500 is provided with a drive circuit 522, and various lamps 520 (upper lamp, lower lamp, side lamp 144, title panel 162 lamp, etc.) are connected to the drive circuit 522.

  The second sub-control unit 500 is provided with a drive circuit 524 that drives the motor of the shutter 163. This drive circuit 524 is a stepping motor (not shown) provided on the shutter 163 in response to a command from the CPU 504. A drive signal is output to.

  The second sub-control unit 500 is provided with a sensor circuit 526, and a shutter sensor 163a is connected to the sensor circuit 526. The CPU 504 monitors the state of the shutter sensor 163a.

  The second sub-control unit 500 includes a drive circuit 517 that drives the fan F2. The basic circuit 502 can control the driving and stopping of the fan F2 via the driving circuit 517. However, the power is always supplied to the fan F2 when the slot machine 100 is turned on without the control of the basic circuit 502. The structure to drive may be sufficient.

<Schematic configuration of circuit board>
The circuit board configuration of the first sub-control unit 400 and the second sub-control unit 500 will be described with reference to FIG. FIG. 4A is a plan view of a sub control board constituting the first sub control unit 400 and the second sub control unit 500. The sub control board includes a circuit board 40 configuring the first sub control unit 400 and a circuit board 50 configuring the second sub control unit 500. The circuit boards 40 and 50 are configured by mounting various components such as an IC and a connector on a printed wiring board, and are electrically connected via the connector 10. In the present embodiment, the connector 10 is a board-to-board connector, and the circuit board 40 and the circuit board 50 are electrically and mechanically connected via the connector 10. The connector 10 includes a connector 11 fixed to the circuit board 40 and a connector 12 fixed to the circuit board 50. By fitting and separating these connectors 11, 12, the circuit boards 40 and 50 are machined. Is detachable. 4A shows a state where the circuit boards 40 and 50 are mechanically connected, and the lower figure shows a state where the circuit boards 40 and 50 are mechanically separated.

  FIG. 4B shows the structure of the substrate storage case 220 and the storage mode of the circuit boards 40 and 50. The substrate storage case 220 can be configured as a single case for storing the entire circuit boards 40 and 50. In this embodiment, the substrate storage case 220A for storing the circuit board 40 and the circuit board 50 are provided. The board storage case 220B is configured to be stored separately. With such a configuration, when one of the circuit board 40 and the circuit board 50 needs to be replaced, it is not necessary to remove the entire board storage case 220 from the slot machine 100, and the board storage case 220A or Without opening the substrate storage case 220B, one of the substrate storage case 220A and the substrate storage case 220B may be removed while the other is attached to the main body, and the substrate replacement operation may be easy.

  The substrate storage case 220A and the substrate storage case 220B can be made of a material that can transmit light (for example, a transparent or translucent material), whereby the state of the internal circuit boards 40 and 50 is visually recognized from the outside. It may be possible.

  FIG. 4C is a cross-sectional view and a partially enlarged view of the substrate storage case 220 taken along the line A-A ′ of FIG. The fan F1 is fixed to an opening formed in the substrate storage case 220A. The fan F1 can be fixed to the circuit board 40. However, by fixing the fan F1 to the board storage case 220A, it may be easy to check the operation from the outside, and the ventilation efficiency in the board storage case 220A is good. There is a case. Although not shown, the substrate storage cases 220A and 220B are formed with a plurality of openings through which a harness connecting an external device and the circuit boards 40 and 50 passes.

  An opening 221a through which the connector 12 is inserted is formed at the end 221 of the board storage case 220B, and an opening 222a through which the connector 11 is inserted is formed at the end 222 of the board storage case 220A. The connectors 11 and 12 are exposed through these openings 221a and 222a and connected to each other so that the end portion 222 of the substrate storage case 220A and the end portion 221 of the substrate storage case 220B abut each other. 40 and 50 can be connected.

  In the case of the present embodiment, one of the end portions 221 and 222 is configured to enter the other. Specifically, the end portion 221 has a concave shape, and the end portion 222 has a shape that enters the concave portion. This may reduce the prevention of fraud. If there is a gap in the connection portion between the board storage case 220A and the board storage case 220B, a foreign substance may be inserted into the gap and the circuit boards 40 and 50 may be cheated. By adopting the structure of the present embodiment, there is a case where the insertion of foreign matter can be suppressed by eliminating or narrowing the gap of the connection portion. The target of foreign object insertion may be aimed at the circuit board 40 constituting the first sub-control unit 400 which is a higher-order control board. However, in the case of the present embodiment, it becomes difficult to insert a foreign object in the D1 direction due to the concave shape of the end portion 221, and it becomes difficult for the foreign object to reach the circuit board 40 if the foreign object is inserted in the D2 direction. In some cases, foreign matter insertion can be suppressed.

  Although not shown, the circuit board 50 is a board provided with the ROM 506, but another board (referred to as a ROM board) may be connected to the circuit board 50, and the ROM 506 may be provided on this board. Since the ROM 506 has many specification changes that are affected by the market price or the like, if the ROM 506 is changed to a different board, it may be possible to cope with the change of the ROM board alone.

  The ROM board may be housed in a dedicated case (referred to as a ROM board case), and the ROM board case may be connected to the circuit board 50 by a board-to-board connector. In some cases, the ROM substrate can be easily attached.

  The board-to-board connector on the circuit board 50 side may be disposed on the surface of the circuit board 50, and the ROM board case (ROM board) may be attached perpendicular to the surface of the circuit board 50. The substrate storage case 220B may include an opening for attaching a ROM substrate case (ROM substrate), and the ROM substrate case may be fixed to the main body side with a fixing member such as a screw. When the substrate storage case 220A, the substrate storage case 220B, and the ROM substrate case are attached to the main body, the substrate storage case 220A and the substrate storage case 220B may be attached first, and the ROM substrate case (ROM substrate) may be attached later. The ROM substrate case (ROM substrate) may have a structure in which the ROM substrate case (ROM substrate) is mounted on the front surface side of the circuit substrate 50 while being moved in a direction perpendicular to the surface of the circuit substrate 50.

  In such a structure, the circuit boards 40 and 50 cannot be removed unless the ROM board case (ROM board) is first removed from the circuit board 50. Therefore, there may be a case where trouble caused by removing the circuit boards 40 and 50 while the ROM board case (ROM board) is attached to the circuit board 50 may be prevented. For example, it may be possible to prevent the circuit board 50 from being damaged due to an unexpected collision with the ROM board case.

  Further, the substrate storage case 220A and the substrate storage case 220B may be cases in which a resin case is plated and the ROM substrate case may be a transparent resin case. Since the surfaces of the substrate storage case 220A and the substrate storage case 220B are mirror-like, in the inspection work, among the electronic components of the ROM substrate, components that are difficult to see from the front are placed on the surfaces of the substrate storage case 220A and the substrate storage case 220B. In some cases, it may be reflected and visible. The substrate storage case 220A and the substrate storage case 220B may be made of a metal case (having a mirror-like surface). In some cases, countermeasures against static electricity may be possible while facilitating inspection work.

<Power supply path>
A power supply voltage supply path from the power supply board 600 to the main control unit 300, the first sub control unit 400, and the second sub control unit 500 will be described with reference to FIG. In the figure, PL indicates a power supply line, and SL indicates a signal line. In the figure, it is also shown that the power supply board 600 and the main controller 300 are arranged on the main body 101 side, and the other components are arranged on the front door 102 side.

  The power supply substrate 600 generates a plurality of types of DC voltages. Here, for example, DC voltages of 12V, 12Vs, and 24V are generated. The difference between 12V and 12Vs is the application, and 12Vs is specialized in the power supply voltage of the CPU (basic circuit) of the main control unit 300. 12V is also used as a power supply voltage for devices other than the CPU.

  The main controller 300 is supplied with DC voltages of 12 Vs and 24 V via a relay board (not shown). The circuit board 50 (second sub-control unit 500) is supplied with DC voltages of 12V and 24V from the power supply board 600. The circuit board 40 (first sub-control unit 400) is not supplied with a DC voltage from the power supply board 600, but is supplied with a DC voltage of 12 V from the power supply board 600 through the circuit board 50. That is, in the case of the present embodiment, in terms of the connection relation of wiring, of the circuit board 40 and the circuit board 50, only the circuit board 50 is connected to the power supply board 600 via the harness. The power supply board 600 is not directly connected.

  A fan F1 is electrically connected to the circuit board 40, and a DC voltage 12V supplied via the circuit board 50 is supplied to the fan F1. Further, in the circuit board 40, 3.3 V is generated from 12 V supplied via the circuit board 50 as described later, and this is supplied to the circuit board 50. In other words, the circuit board 40 is configured to transform the voltage supplied from the circuit board 50 and return it to the circuit board 50.

  The circuit board 50 is electrically connected to the boards of the fan F2, the effect image display device 157, the shutter 163, and the various lamps 520, and is supplied with 12V as a power supply voltage. Further, a signal voltage is supplied to the circuit board 50 to the speakers 272 and 277. Further, the circuit board 50 generates 5.0V from 12V supplied from the power supply board 600 as will be described later, and this is supplied to each of the effect buttons 150 and 151.

<Detailed configuration of circuit board>
The configuration of the circuit boards 40 and 50 will be further described. FIG. 6 shows an arrangement example of connectors on the circuit boards 40 and 50. The connector CN1 is the connector 10 described above, and is a board-to-board connector that electrically and mechanically connects the circuit board 40 and the circuit board 50.

  Connectors CN2 to CN9 are connectors that are connected to external devices via a harness. The circuit board 40 is provided with connectors CN2 and CN3. A harness for communication with the main control unit 300 is connected to the connector CN2. A harness for the fan F1 is connected to the connector CN3.

  The circuit board 50 is provided with connectors CN4 to CN9. A harness for effect buttons 150 and 151 is connected to connector CN4. The connector CN4 can be provided for each of the effect buttons 150 and 151. A harness for the speakers 272 and 277 is connected to the connector CN5. The connector CN5 can be provided for each speaker 272, 277. A harness for the effect image display device 157 is connected to the connector CN6. The board of the effect image display device 157 and the circuit board 50 may be connected by a board-to-board connector.

  A harness for the shutter 163 is connected to the connector CN7. The connector CN7 can be provided for each of the right shutter and the left shutter. A harness for the fan F2 is connected to the connector CN8. A harness for the power supply board 600 is connected to the connector CN9. Connector CN9 is the only connector connected to power supply board 600 on circuit boards 40 and 50.

  With reference to FIG. 7, the connection relation of the power supply lines will be mainly described. FIG. 7 is a diagram illustrating some components on the circuit boards 40 and 50, wirings related to supply of power supply voltage, and the like.

  The circuit board 50 is provided with an amplifier 53 for amplifying driving signals of the speakers 272 and 277, and the amplifier 53 is supplied with the 24V DC voltage of the power supply board 600 from the connector CN9. The 12V DC voltage of the power supply board 600 is supplied to the circuit wiring 54 from the connector CN9. A DC / DC converter 52 is connected to the circuit wiring 54. The DC / DC converter 52 generates a DC voltage of 5.0 V and supplies the DC voltage of 5.0 V to each part on the circuit board 50. The circuit wiring 54 is connected to the connectors CN6 to CN8, and a DC voltage of 12V is supplied as a power supply voltage to an external device connected to the connectors CN6 to CN8.

  The circuit wiring 54 is also connected to the circuit wiring 42 via a connection line PL1 which is one of the circuit wirings of the connector 10, and a DC voltage of 12V is supplied to the circuit board 40 via the connector 10. The circuit wiring 42 is connected to the connector CN3, and a DC voltage of 12V is supplied as a power supply voltage to an external device connected to the connector CN3. A DC / DC converter 41 is also connected to the circuit wiring 42. The DC / DC converter 41 generates a DC voltage of 3.3 V and supplies it to the ROM 406 and the basic circuit 402 via the circuit wiring 43. The basic circuit 402 and the ROM 406 operate using a 3.3V DC voltage as a power supply voltage.

  The circuit wiring 43 is also connected to the circuit wiring 55 of the circuit board 50 via a connection line PL2 which is one of the circuit wirings of the connector 10. A DC / DC converter 51 of the circuit board 50 is connected to the circuit wiring 55. The DC / DC converter 51 generates a DC voltage of 2.0 V and supplies it to the basic circuit 502. The basic circuit 502 operates using a DC voltage of 2.0 V as a power supply voltage.

  Although not shown, the VDP 516 provided on the circuit board 50 may also be configured to receive a DC voltage of 2.0 V from the DC / DC converter 51 and operate as a power supply voltage. Further, the other DC voltage required for the basic circuit 502 can be generated from other voltages (5.0 V, 12 V, 24 V) on the circuit board 50 by a DC / DC converter.

  The connector 10 has a plurality of signal connection lines SL, and communication between the basic circuit 402 and the basic circuit 502 is possible.

  As described above, in the circuit boards 40 and 50 of this embodiment, the DC voltage from the power supply board 600 is input to the circuit board 50, and the power supply voltage is input to the circuit board 40 via the connector 10 through the circuit board 50. Is done. Therefore, when the electrical connection between the circuit board 40 and the circuit board 50 is disconnected in the connector 10, the power supply voltage is not supplied to the basic circuit 402, and the operation may be stopped to prevent malfunction.

  Among the voltages required for the circuit board 50, a DC voltage of 2.2V is generated from 3.3V supplied from the circuit board 40 via the connector 10, and the basic circuit 502 and the like operate. Therefore, when the electrical connection between the circuit board 40 and the circuit board 50 is cut off in the connector 10, the power supply voltage is not supplied to the basic circuit 502, and the operation may be stopped to prevent malfunction.

  Even when the electrical connection between the circuit board 40 and the circuit board 50 in the connector 10 is cut off by the DC voltage from the power supply board 600 being input to the circuit board 50, the amplifier 53 and the connectors CN4 to The supply of the power supply voltage is continued to the external device connected to 8. Therefore, when the circuit board 40 and the circuit board 50 are reconnected in the connector 10 and the basic circuits 402 and 502 are restored, the restoration of the external device in which the supply of the power supply voltage is maintained may be accelerated.

  Further, since the sub-control board is composed of the circuit board 40 and the circuit board 50, the circuit board 40 can be shared by a plurality of models, and the circuit board 50 can be changed according to the model, and various circuits can be used. It may be easy to construct a substrate.

  Next, the pin arrangement and the like of the connector 10 will be described with reference to FIG. 8A is a diagram showing a positional relationship between the connector 10 and the connectors CN8 and CN9, and FIG. 8B is a diagram showing circuit wiring (pin arrangement) of the connector 10. As shown in FIG. The connector CN9 is a connector having pins for power supply lines (power supply pins supplied from the power supply board 600 to the circuit board 50), and the connector CN8 is a pin for power supply lines (from the circuit board 50 to the fan F2). It is a connector provided with the pin for power supplies supplied to.

  In this embodiment, the connector CN9 is closest to the connector 10, and the connector CN8 is next closest to the connector 10. In terms of distance, the distance L1 between the connector 10 and the connector CN9 is shorter than the distance L2 between the connector 10 and the connector CN8, and is the shortest distance between the connector 10 and another connector. Thereby, the circuit wiring which supplies DC voltage 12V with respect to the circuit board 40 can be shortened, and the area reduction and reduction of the influence of noise may be aimed at. In some cases, it can be suggested that noise is mixed from a circuit wiring that supplies a DC voltage of 12 V to other circuit wiring.

  That is, among the connectors on the circuit board 50, the connector CN9 to which voltage is supplied from the power supply board 600 is arranged closer to the connector 10 than the other connectors. Furthermore, among the pins for the power supply line of the connector CN9, the pin with the DC voltage of 12V may be arranged closer to the connector 10 than the other power supply line pins. In some cases, the distance between the connector CN9 and the connector 10 can be minimized. In addition, you may make it not arrange | position components between the connector CN9 and the connector 10. FIG. In some cases, the circuit wiring for supplying the DC voltage 12V to the circuit board 40 can be shortened to the shortest.

  The connector 10 has a plurality of connection lines formed in a row in the D3 direction, and each connection line has a pin P on the circuit board 40 side and a pin P on the circuit board 50 side. Each connection line is the same, but the power line pin P may be made thicker than the signal line pin P, which may enable stable power supply. In the case of this embodiment, the D3 direction is a direction along the end sides of the circuit boards 40 and 50.

  When the connector 10 is divided into the center portion DL and the end portions EL1 and EL2 in the D3 direction, the connection line of the center portion DL is used as a signal line (signal connection line) SL and the connection line used as a power supply line (power supply connection line). The connection lines of the end portions EL1 and EL2 are used for PL1 and PL2. As a result, the 12V power line PL1 and the 3.3V power line PL2 can be positioned away from each other, and the influence of noise on each other may be reduced.

  Note that each of the connection lines PL1 and PL2 may be a plurality of connection lines so that stable power supply can be performed. Further, the connection line PL1 having a higher voltage may use more connection lines than the connection line PL2 having a lower voltage so that more stable power supply can be performed. The connection lines PL1 and PL2 may be connection lines located at the end of all the connection lines, or are used when there are unused connection lines at both ends of the connection line of the connector 10. The connection line located at the end of the connection line may be used.

  The distance L11 is shorter between the distance L11 between the power connection line PL1 and the connector CN9 and the distance L12 between the power connection line PL2 and the connector CN9. In the present embodiment, the connection line closest to the connector CN9 is the power connection line PL1, and the connection line farthest is the power connection line PL2. In these configurations, the circuit wiring for supplying the DC voltage 12V to the circuit board 40 can be shortened, and the area can be reduced and the influence of noise can be reduced. The DC voltage 12V is supplied. In some cases, it can be suggested that noise is mixed from circuit wiring to other circuit wiring. In addition, the degree of freedom in the arrangement of circuit wiring for supplying a DC voltage of 3.3 V to the circuit board 50 may increase. The connection line employed as the power supply line PL1 may be the connection line closest to the connector PN9 among the connection lines used. Similarly, the connection line employed as the power supply line PL1 may be the connection line farthest from the connector PN9 among the connection lines used.

  The voltage monitoring circuits A and B will be described with reference to FIG. The voltage monitoring circuit A is provided on the circuit board 40 and monitors the 3.3V DC voltage generated by the DC / DC converter 41. The voltage monitoring circuit B has the configuration of the first sub-control unit 400, but is provided on the circuit board 50 and monitors the 12V DC voltage supplied from the power supply board 600 to the connector CN9.

  The voltage monitoring circuit A monitors the voltage on the circuit wiring of the DC voltage generated by the DC / DC converter 41, and when a threshold value (for example, 3.1 to 3.2 V) is reached, a start signal (reset signal) is sent to the basic circuit. Even when there is an abnormality (for example, when the voltage drops to a threshold value (eg, 2.4 to 2.8 V) or less), a reset signal is output to the CPU 404 of the basic circuit 402 as an interruption signal.

  The voltage monitoring circuit B monitors the voltage on the circuit wiring of the DC voltage of 12V input to the connector CN9, and when there is an abnormality (for example, when the voltage drops below a threshold value (for example, 10.5 to 11.0V)) The voltage drop signal is output to the basic circuit 402. When the voltage drop signal is received, the CPU 404 executes a backup process described later.

  In the present embodiment, the voltage monitoring circuit B is configured to be controlled by the CPU 404 of the basic circuit 402. The CPU 404 of the basic circuit 402 outputs an instruction signal that instructs the voltage monitoring circuit B to output a signal at a predetermined cycle. When the voltage monitoring circuit B receives the instruction signal, the voltage drop signal is output when there is a voltage abnormality. Is output to the CPU 404. This is because the CPU 404 is provided on the circuit board 40 and operates with a DC voltage of 3.3V as a power supply voltage, while the voltage monitoring circuit B is provided on the circuit board 50 and monitors the DC voltage 12V. That is, there is a possibility that the voltage monitoring circuit B may output a voltage drop signal to the CPU 404 in a state where the CPU 404 may not be in a normal operating state, and the CPU 404 executes backup processing at an unexpected timing. The case is to avoid.

  The voltage monitoring circuit B can activate a function (automatic return function) for resetting its state after giving a voltage drop signal to the CPU 404 when there is a voltage drop. This function can avoid the continuous output of the voltage drop signal. For example, the automatic return function can be activated when 3 seconds have elapsed after the voltage drop signal is sent to the basic circuit 402. In this case, once the CPU 404 receives the voltage drop signal, the operation of the voltage monitoring circuit B is stopped to prevent the voltage drop signal from being output again.

  Note that the second sub-control unit 500 may be provided with a voltage monitoring circuit, and may have the same processing and configuration as the first sub-control unit 400. In this case, some voltage monitoring circuits may be provided on the circuit board 40.

  The configuration of the fans F1 and F2 and the circuit boards 40 and 50 will be described with reference to FIG. The figure shows the rear upper part of the front door 102. The fan F1 is connected to the connector CN3 of the circuit board 40 via the harness H1, and the fan F2 is connected to the connector CN8 of the circuit board 50 via the harness H2.

  As described above, when the electrical connection between the circuit boards 40 and 50 is cut off in the connector 10, the power supply voltage (12V) is not supplied to the circuit board 40, and the fan F1 stops. Therefore, it may be easy to visually recognize that the electrical connection between the circuit boards 40 and 50 is broken, and the connection state between the circuit board 40 and the circuit board 50 may be easily confirmed.

  On the other hand, even if the electrical connection between the circuit boards 40 and 50 is cut off in the connector 10, the power supply voltage (12V) is supplied to the circuit board 50, so that the fan F2 can be driven. Therefore, it may be easy to distinguish whether the electrical connection between the circuit boards 40 and 50 is bad or the power supply board 600 is bad by comparing the operations of the fans F1 and F2.

  On the circuit board 40, the basic circuit 402 can be arranged on the surface on the fan F1 side to improve the cooling effect. On the other hand, the crystal oscillator 414 can be disposed on a surface opposite to the fan F1 side (a position directly below the basic circuit 402). Thereby, the influence of noise of the fan F1 etc. can be reduced.

  With reference to FIG. 11 and FIG. 12, the input mode of error information and effect buttons 150 and 151 will be described. The error information is output information of a sensor that detects an error.

  In the case of the present embodiment, the effect buttons 150 and 151 have a total of five electrical contacts, and the ON / OFF information thereof is 5-bit information. If a plurality of pieces of error information are added, the number of bits increases, and the number of ports of the input interface of the basic circuit 402 may be insufficient. Therefore, input by serial communication can be employed.

  As shown in FIG. 11A, various types of error information are configured to be input to the 8-bit shift register 20, and the operation results of the effect buttons 150 and 151 are input to the 8-bit shift register 20. It is configured to be entered. In the present embodiment, since the connector CN4 to which the effect buttons 150 and 151 are connected is provided on the circuit board 50, the sensor circuit 414 is provided on the circuit board 50. The sensor circuit 414 may be provided outside the circuit board 50 and the connector CN4 may be connected to the sensor circuit 414.

  As shown in FIG. 11B, the output terminal Q of the shift register 21 is connected to the input terminal DS of the shift register 20. The output terminal Q of the shift register 20 is connected to the SI port of the basic circuit 402. The SCK port of the basic circuit 402 that generates the clock signal is connected to the SCK terminals of the shift registers 20 and 21. The CS port of the basic circuit 402 that generates the chip select signal is connected to each CS terminal of the shift registers 20 and 21. The GPIO port of the basic circuit 402 is connected to each PL terminal of the shift registers 20 and 21.

  The operation will be described. When the GPIO port becomes low level, the input of each D terminal is taken into the shift registers 20 and 21. When CS is set to Low level and the shift registers 20 and 21 are selected and a clock signal is output from the SCK port, the captured 8-bit information is output from the Q terminal in synchronization with this shift. Error information is sequentially output from the Q terminal of the shift register 20, and subsequently, the detection results of the effect buttons 150 and 151 output from the shift register 21 to the DS terminal of the fist register 20 are output.

  FIG. 12A shows an example of a signal sequence output from the Q terminal of the shift register 20. In the present embodiment, different types of information with different priorities are included in the information captured at a time. Of the 16-bit data, the first 8 bits are assigned to the error information, and the latter 8 bits are assigned to the operation information of the effect buttons 150 and 151. The error information is, for example, information output by the amplifier 53. Specifically, the error information is information output by the amplifier 53 having a function of monitoring the input power supply when the input power supply falls below a threshold value. . Other information may be used as long as the information is output from an electronic component that can output information on abnormality.

  By assigning error information to the first 8 bits, the priority is increased and the information is transmitted preferentially to the basic circuit 402. Among the various types of error information and the information on the operation results of the effect buttons 150 and 151, the various types of error information have higher priority than the information on the operation results of the effect buttons 150 and 151. This is because there is a case where the disadvantage to the store side and the player side can be minimized by executing the processing corresponding to the error information with the highest priority.

  When the basic circuit 402 reads various types of error information and information about the operation results of the effect buttons 150 and 151, even if all the information is not captured for some reason, the various types of error information are given priority. Since it is received, it may be possible to perform processing based on various types of error information.

  FIG. 12B shows the information content of each bit. L fixed is an unused bit fixed at the Low level, and General Purposes 1 to 3 are unused bits. Power failures 1 to 3 are, for example, errors related to the power supply voltage, and errors 1 to 3 are errors of other circuit elements, for example. The effect button 1 indicates the operation result of the effect button 150, and the effect buttons 2 to 5 indicate the up / down / left / right operation results of the effect button 151.

<Pattern arrangement>
A symbol arrangement applied to each of the reels 110 to 112 will be described with reference to FIG. This figure is a diagram in which the arrangement of symbols applied to each reel (left reel 110, middle reel 111, right reel 112) is developed in a plane.

  In each reel 110 to 112, a plurality of types (eight types in this embodiment) of symbols shown on the right side of the figure are arranged in a predetermined number of frames (21 frames of numbers 0 to 20 in this embodiment). Also, numbers 0 to 20 shown at the left end of the figure are numbers indicating the arrangement positions of symbols on the reels 110 to 112. For example, in the present embodiment, the “replay” symbol for the number 1 frame on the left reel 110, the “bell” symbol for the number 0 frame on the middle reel 111, and the “bell” symbol for the number 2 frame on the right reel 112. "Watermelon" design is arranged respectively.

<Type of winning prize>
Next, the types of winning combinations of the slot machine 100 will be described with reference to FIG. This figure shows the types of winning combinations (including actuating combinations), symbol combinations corresponding to each winning combination, and the operation or payout of each winning combination. Among the winning combinations in the present embodiment, the special combination (Big Bonus: BB1, BB2 Regular Bonus: RB) is a combination that shifts to a bonus game, and the replay (replay) is a replay without newly inserting a medal. Each winning combination is sometimes distinguished from a winning combination and sometimes called an “acting combination”. However, in the “winning combination” in this embodiment, a big bonus, a regular bonus, and a replay that are operating combinations are included. included. In addition, “winning” in the present embodiment includes a case where a symbol combination of an actuator not accompanied by a medal payout (without medal payout) is displayed on an active line, for example, a big bonus, regular Includes bonuses and replay wins.

  The winning combination of the slot machine 100 includes a big bonus (BB1, BB2), a regular bonus (RB), a small combination (cherry, watermelon, bell), and replay (replay). Needless to say, the type of winning combination is not limited to this and can be arbitrarily adopted.

  “Big Bonus (BB1, BB2)” (hereinafter sometimes simply referred to as “BB”) is a special combination (operating combination) in which a big bonus game (BB game), which is a special game, is started by winning a prize. . Corresponding symbol combinations are “white 7-white 7-white 7” for BB1, and “blue 7-blue 7-blue 7” for BB2. Further, flag carryover is performed for BB1 and BB2. That is, when BB1 and BB2 are won internally, a flag indicating this is set (stored in a predetermined area of the RAM 308 of the main control unit 300), but even if BB1 and BB2 are not won in the game, a prize is won. Until then, the flag indicating the internal winning is maintained, and even after the next game, BB1 and BB2 are being internally selected, and the symbol combination corresponding to BB1 “white 7-white 7-white 7”, the symbol corresponding to BB2 The combination “blue 7-blue 7-blue 7” is in a state of winning a prize.

  The “regular bonus (RB)” is a special combination (operating combination) in which a regular bonus game (RB game) is started by winning. The corresponding symbol combination is “bonus-bonus-bonus”. Note that the RB carries over the flag as well as the above-mentioned BB. However, in the big bonus game (BB game) (details will be described later), the regular bonus game (RB game) is won internally and the combination of symbols is displayed on the winning line. In addition, the regular bonus game is started after the start of the big bonus game, and when the regular bonus game is finished once, the regular bonus game is automatically started so that the next regular bonus game starts immediately. It is good.

  “Small 1 to 3 (cherry, watermelon, bell)” (hereinafter sometimes simply referred to as “cherry”, “watermelon”, “bell”) is a winning combination in which a predetermined number of medals are paid out. Corresponding symbol combinations are “cherry-ANY-ANY” for cherry, “watermelon-watermelon-watermelon” for watermelon, and “bell-bell-bell” for bell. The corresponding payout number is as shown in FIG. In the case of “cherry-ANY-ANY”, the symbol of the left reel 110 may be “cherry”, and the symbol of the middle reel 111 and the right reel 112 may be any symbol.

  “Replay” is a winning combination (operating combination) in which a game can be performed without inserting a medal (game medium) in the next game by winning, and no medal is paid out. The corresponding symbol combination is “replay-replay-replay” for replay.

<Type of gaming state>
Next, the types of gaming state of the slot machine 100 will be described. The gaming state is information for identifying the type of lottery data selected in a lottery or the like. In the present embodiment, the gaming state of the slot machine 100 is roughly classified into a normal game, a BB game, an RB game, and an internal winning game of a big bonus (BB) and a regular bonus (RB). However, the internal winning game may be a division included in the normal game.

<Normal game>
The winning combinations that are internally won for normal games include a big bonus (BB), regular bonus (RB), replay (replay), and small roles (cherry, watermelon, bell).

  “Big Bonus (BB)” is a special combination (operating combination) in which a big bonus game (BB game), which is a special game, is started by winning. “Regular Bonus (RB)” is a special combination (operating combination) that starts a regular bonus game (RB game) upon winning. The “replay” (replay) is a winning combination (operating combination) in which a game can be performed without a medal being inserted in the next game by winning, and no medal is paid out. The “small role” is a winning combination in which a predetermined number of medals are paid out by winning. In addition, the internal winning probability of each combination is a range of random values obtained at the time of internal lottery from numerical data corresponding to the range of lottery data associated with each combination from lottery data prepared for normal games. It is calculated by the value divided by the numerical data (for example, 65535). The lottery data prepared for the normal game is divided into several numerical ranges in advance, and each combination and lose is associated with each numerical range. It is determined whether the random number value obtained as a result of executing the internal lottery is a value corresponding to the lottery data corresponding to which combination, and the internal lottery combination is determined. This lottery data is provided with settings 1 to 6 in which the winning probabilities of at least one combination are different, and a game shop clerk can arbitrarily select and set any set value.

  In the normal game, the internal lottery result is almost lost (big bonus (BB), regular bonus (RB), replay (replay) and small role won), or any stop display result A setting is made so that the stop display result of the losing that does not correspond to the symbol combination of the combination is generally derived, and the total number of medals to be acquired is less than the total number of inserted medals. Therefore, it is a gaming state that is disadvantageous for the player. However, when a predetermined condition is satisfied (for example, when a specific symbol combination is displayed), it is a gaming state that may be changed to increase the probability of internal winning of replaying. In this case, Consumption of medals used for games is suppressed, and a predetermined number of medals are paid out by winning a small role, resulting in a gaming state where the total number of medals exceeds the total number of medals inserted, which is beneficial to the player. May become a gaming state.

<BB game>
The BB game can be set to be in a gaming state that is beneficial to the player. For example, the BB game is in a gaming state in which the total number of medals to be acquired exceeds the total number of medals inserted. In this embodiment, the BB game is started by winning a big bonus (BB), and an RB game (described later) can be continuously executed repeatedly, and a predetermined number (for example, during the game) The process ends when more than 465 medals are obtained. However, the BB game only needs to be able to execute the RB game a plurality of times. For example, when a combination (for example, replay-replay-replay) is set for starting the RB game, and this combination is won internally, or The RB game may be set to start when winning. Furthermore, in the BB game, when the BB general game excluding the RB game during the BB game is executed a predetermined number of times (for example, 30 times), or the number of the RB games executed during the BB game is a predetermined number of times. It may be made to end when it reaches (for example, three times).

<RB game>
The RB game can be set to be in a gaming state that is beneficial to the player. For example, an RB game is in a gaming state in which the total number of medals acquired exceeds the total number of medals inserted. In this embodiment, the RB game is started by winning a regular bonus (RB), and a predetermined role is set to a variation that increases the probability of internal winning (for example, “setting 1” or “normal game”). The internal winning probability 1/15 of “small role 1” is increased to an internal winning probability 1 / 1.2, which is a predetermined value), and a predetermined number (for example, 8 times) It ends when there is a prize. In the RB game, when a predetermined number of times (at least 2 times) is won (for example, 8 times), or when the number of RB games executed during the RB game reaches a predetermined number of times (for example, (8 times). Since the BB game described above can execute the RB game a plurality of times, when a single RB game is performed, the number of medals less than the total number of medals obtained in the BB game is acquired and terminated. Become.

<Big winning (BB) and regular bonus (RB) internal winning games>
The winning combination that is internally won for the internal winning game of the big bonus (BB) and the regular bonus (RB) includes a replay and a small role. The big bonus (BB) and the regular bonus (RB) are not won internally, and are game states in which a symbol combination corresponding to the big bonus (BB) or the regular bonus (RB) can be won.

  However, the probability of the internal winning of the replay may be changed from the next game internally won in the big bonus (BB) and the regular bonus (RB), for example, the probability of increasing the internal winning probability of the replay is changed. Until the symbol combination corresponding to the big bonus (BB) and regular bonus (RB) wins, the total number of medals to be acquired is set to a gaming state that is substantially the same as the total number of inserted medals and is compared with the normal game. The gaming state may be beneficial to the player. It should be noted that BB game and RB game are both game states that are beneficial to the player, and may be generally referred to as bonus games or special games.

<Processing example of control unit>
<Main control unit main processing>
The main control unit main process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main processing of the main control unit.

  As described above, the main control unit 300 is provided with the start signal output circuit (reset signal output circuit) 338 that outputs the start signal (reset signal) when the power is turned on. The CPU 304 of the basic circuit 302 to which this activation signal has been input resets by a reset interrupt and executes the main process of the main control unit shown in FIG. 14 according to a control program stored in the ROM 306 in advance.

  When power is turned on, first, various initial settings are made in step SA01. In this initial setting, setting of the stack initial value to the stack pointer (SP) of the CPU 304, setting of interrupt inhibition, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, operation permission to the WDT 313, and initial setting Set the value. In step SA02, medal insertion / start operation acceptance processing is executed. Here, it is checked whether or not a medal has been inserted, and the winning line display lamp 120 is turned on in response to the insertion of the medal. Note that when a re-win is won in the previous game, a process of inserting the same number of medals as the number of medals inserted in the previous game is performed, so that it is not necessary for the player to insert medals. In step SA03, it is checked whether the start lever 135 has been operated. If the start lever 135 has been operated, the process proceeds to step SA05.

  In step SA05, the number of inserted medals is determined, and an effective winning line is determined. In step SA07, the random number generated by the random number generation circuit 316 is acquired. In step SA09, the winning combination lottery table stored in the ROM 306 is read according to the current gaming state, and an internal lottery is performed using this and the random value acquired in step SA07. As a result of the internal lottery, when any winning combination (including an operating combination) is won internally, the flag of the winning combination is turned ON. In step SA11, reel stop data is selected based on the internal lottery result.

  In step SA13, rotation of all reels 110 to 112 is started. In step SA15, the stop buttons 137 to 139 can be received. When any one of the stop buttons is pressed, the reel stop control in which one of the reels 110 to 112 corresponding to the pressed stop button is selected in step SA11. Stop based on data. When all the reels 110 to 112 are stopped, the process proceeds to Step SA17.

  In step SA17, winning determination is performed. Here, when a picture combination corresponding to some winning combination is displayed on the activated winning line 114, it is determined that the winning combination is won. For example, if “bell-bell-bell” is arranged on the activated winning line, it is determined that the small role (bell) is won. In step SA19, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out according to the number of winning lines.

  In step SA21, game state control processing is performed. In the game state control process, a process related to transition of each game state of normal game, BB game, RB game, and internal winning game is performed, and the game state is shifted when those start conditions and end conditions are satisfied. Thus, one game is completed. Thereafter, the game proceeds by returning to step SA03 and repeating the above-described processing.

<Main controller 300 timer interrupt processing>
The main control unit timer interrupt process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of the main control unit timer interrupt process.

  The main control unit 300 includes a counter timer 312 that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 2 ms), and the main control unit timer interrupt is triggered by this timer interrupt signal. The process is started at a predetermined cycle.

  In step SB01, timer interrupt start processing is performed. In this timer interrupt start process, a process of temporarily saving each register value of the CPU 304 to the stack area is performed.

  In step SB03, the WDT is periodically updated (so that the count value of the WDT 314 exceeds the initial setting value (32.8 ms in the present embodiment) and no WDT interrupt occurs (so as not to detect a processing abnormality). In the embodiment, the restart is performed once every about 2 ms, which is the period of the main control unit timer interrupt.

  In step SB05, input port state update processing is performed. In this input port status update process, the detection signals of the sensor circuits 320 of the various sensors 318 are input via the input ports of the I / O 310 to monitor the presence or absence of the detection signals, and each of the various sensors 318 is partitioned in the RAM 308. Store in the provided signal state storage area.

  In step SB07, various game processes are performed. Specifically, an interrupt status is acquired (various interrupt statuses are acquired based on signals from various sensors 318), and processing according to this status is performed (for example, the interrupt status of each acquired stop button 137 to 139). Based on the stop button reception process). In step SB09, timer update processing is performed. Various timers are updated for each time unit.

  In step SB11, command setting transmission processing is performed, and various commands are transmitted to the first sub-control unit 400. Note that the output schedule information transmitted to the first sub-control unit 400 is composed of 16 bits in the present embodiment, bit 15 is strobe information (indicating that data is set when ON), bit 11 -14 are command types (in this embodiment, basic command, start lever reception command, production command accompanying production lottery processing, rotation start command accompanying the start of rotation of reels 110 to 112, and operation of stop buttons 137 to 139. Bits 0 to 10 are command data (a stop button reception command accompanying the stop processing of the reels 110 to 112, a payout number command accompanying the medal payout processing, a payout end command, a command indicating a gaming state, etc.). Predetermined information corresponding to the command type).

  In the first sub-control unit 400, it is possible to determine the production control according to the change of the game control in the main control unit 300 by the command type included in the received output schedule information, and it is included in the output schedule information. Based on the information of the command data, the contents of effect control can be determined.

  In step SB13, an external output signal setting process is performed. In this external output signal setting process, game information stored in the RAM 308 is output to an information input circuit 652 separate from the slot machine 100 via the information output circuit 334.

  In step SB15, device monitoring processing is performed. In this device monitoring process, first, the signal states of the various sensors 318 stored in the signal state storage area in step SB05 are read to monitor the presence / absence of errors relating to medal insertion abnormality and medal payout abnormality. Error processing (not shown) is executed. Further, according to the current gaming state, the medal selector 170 (medal blocker in which the solenoid provided in the medal selector 170 operates), various lamps 338, and various 7-segment (SEG) indicators are set.

  In step SB17, it is monitored whether or not the low voltage signal is on. Then, when the low voltage signal is on (when power supply cutoff is detected), the process proceeds to step SB21. When the low voltage signal is off (power supply cutoff is not detected), the process proceeds to step SB19.

  In step SB19, various processes for ending the timer interrupt end process are performed. In this timer interrupt end process, the value of each register temporarily saved in step SB01 is set in each original register. Thereafter, the process returns to the main process of the main control unit shown in FIG.

  On the other hand, in step SB21, a specific variable or stack pointer for returning to the power-off state at the time of power recovery is saved as a return data in a predetermined area of the RAM 308, and power-off processing such as initialization of input / output ports is performed. After that, the process returns to the main process of the main control unit shown in FIG.

<Processing of First Sub-Control Unit 400>
The process of the 1st sub control part 400 is demonstrated using FIG. FIG. 16A is a flowchart of main processing executed by the CPU 404 of the first sub-control unit 400. FIG. 16B is a flowchart of command reception interrupt processing of the first sub control unit 400. FIG. 16C is a flowchart of the timer interrupt process of the first sub control unit 400.

  First, in step SC01 in FIG. 16A, various initial settings are performed. When the power is turned on, an initialization process is first executed in step SC01. In this initialization processing, initialization of input / output ports, initialization processing of a storage area in the RAM 408, and the like are performed.

  In step SC03, it is determined whether or not the timer variable is 10 or more. This process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or more, the process proceeds to step SC05. In step SC05, 0 is assigned to the timer variable.

  In step SC06, processing for obtaining the operation detection result of the effect buttons 150 and 151 described with reference to FIGS. 11 and 12 and error information is performed.

  In step SC07, command processing is performed. In the command processing, the CPU 404 of the first sub control unit 400 determines whether a command is received from the main control unit 300.

  In step SC09, an effect control process is performed. For example, processing based on the result of step SC06 is performed. If there is a new command in step SC07, processing corresponding to this command is performed. This process includes, for example, performing a process such as reading effect data from the ROM 406 and performing an effect data update process when the effect data needs to be updated.

  In step SC11, sound control processing is performed based on the processing result of step C09. For example, processing related to sound output from the speakers 272 and 277 is performed. In step SC13, lamp control processing is performed based on the processing result of step C09. For example, processing related to various lamps 420 is performed. In step SC15, shutter control processing is performed based on the processing result of step C09. For example, processing related to the operation of the shutter 163 is performed.

  In step SC17, an information output process is performed for setting to transmit a control command to the second sub-control unit 500 based on the processing results of steps C09 to SC15. Thereafter, the process returns to step SC03.

  Next, the command reception interrupt process of the first sub control unit 400 will be described with reference to FIG. This command reception interrupt process is a process executed when the first sub-control unit 400 detects a strobe signal output from the main control unit 300. In step SD01 of the command reception interrupt process, the command output from the main control unit 300 is stored as an unprocessed command in a command storage area provided in the RAM 408.

  Next, the first sub control unit timer interrupt process executed by the CPU 404 of the first sub control unit 400 will be described with reference to FIG. The first sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and the timer interrupt process is performed by using the timer interrupt as a trigger. Execute in the cycle.

  In step SE01, 1 is added to the value of the timer variable storage area of the RAM 408 described in step SC03 in the first sub control unit main process shown in FIG. 16A, and the result is stored in the original timer variable storage area. Therefore, in step SC03, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

  In step SE03, transmission of a control command to the second sub-control unit 500 set in step SC15, an effect random number update process, and the like are performed.

  In step SE05, a power interruption process is performed. FIG. 17 is a flowchart of the power interruption process. In step SE07, it is determined whether or not a voltage drop signal is received from the voltage monitoring circuit B. If received, the process proceeds to step SE08 to perform backup processing. In the backup process, a process of saving a specific variable or stack pointer for returning to the power-off state at the time of power recovery to a predetermined area of the RAM 508 as return data is performed. More specifically, the checksum value is saved after the checksum calculation, writing to the RAM 508 is prohibited, interrupt timers are disabled, interrupts are disabled, and the like. When the voltage drop proceeds, the voltage monitor circuit A detects a voltage drop of the 3.3V power supply, and a reset signal is output from the voltage monitor circuit A to the CPU 404. The CPU 404 performs a startup process, but the power supply disappears and then stops.

<Processing of Second Sub-Control Unit 500>
The process of the second sub control unit 500 will be described with reference to FIG. FIG. 18A is a flowchart of main processing executed by the CPU 504 of the second sub-control unit 500. FIG. 18B is a flowchart of command reception interrupt processing of the second sub control unit 500. FIG. 18C is a flowchart of the timer interrupt process of the second sub control unit 500. FIG. 18D is a flowchart of the image control process of the second sub control unit 500.

  When the power is turned on, an initialization process is first executed in step SF01. In this initialization process, input / output port initialization, storage area initialization in the RAM 508, and the like are performed.

  In step SF03, it is determined whether or not the timer variable is 10 or more. This process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or more, the process proceeds to step SF05. In step SF05, 0 is assigned to the timer variable. In step SF07, command processing is performed. In the command processing, the CPU 504 of the second sub control unit 500 determines whether a command is received from the CPU 404 of the first sub control unit 400.

  In step SF09, an effect control process is performed. For example, if there is a new command in step SF07, processing corresponding to this command is performed. This process includes, for example, performing a process such as reading effect data from the ROM 506 and performing an effect data update process when the effect data needs to be updated.

  In step SF11, image control processing is performed based on the processing result of step SF09. For example, if there is an image control command in the effect data read in step SF09, image control corresponding to this command is performed, and the process returns to step SF03.

  Next, the command reception interrupt process of the second sub control unit 500 will be described with reference to FIG. This command reception interrupt process is a process executed when the second sub control unit 500 detects the strobe signal output from the first sub control unit 400. In step SG01 of the command reception interrupt process, the command output from the first sub-control unit 400 is stored as an unprocessed command in a command storage area provided in the RAM 508.

  Next, the second sub control unit timer interrupt process executed by the CPU 504 of the second sub control unit 500 will be described with reference to FIG. The second sub-control unit 500 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and the timer interrupt process is predetermined by using the timer interrupt as a trigger. Execute in the cycle.

  In step SH01, 1 is added to the value of the timer variable storage area of the RAM 508 described in step SF03 in the second sub-control unit main process shown in FIG. 18A, and the result is stored in the original timer variable storage area. Therefore, in step SF03, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10). In step SH03, an effect random number update process is performed.

  Next, the image control process in step SF13 in the main process of the second sub-control unit 500 will be described with reference to FIG. FIG. 5 is a flowchart showing the flow of image control processing.

  In step SI01, an instruction to transfer image data is issued. Here, the CPU 504 first swaps the designation of the display areas A and B in the VRAM 536. As a result, an image of one frame stored in the display area not designated as the drawing area is displayed on the effect image display device 157. Next, the CPU 504 sets ROM coordinates (transfer source address of the ROM 506), VRAM coordinates (transfer destination address of the VRAM 536), and the like in the attribute register of the VDP 534 based on the position information table, and then the image from the ROM 506 to the VRAM 536. Set an instruction to start data transfer. The VDP 534 transfers the image data from the ROM 506 to the VRAM 536 based on the command set in the attribute register. Thereafter, the VDP 534 outputs a transfer end interrupt signal to the CPU 504.

  In step SI03, it is determined whether or not a transfer end interrupt signal is input from VDP 534. If a transfer end interrupt signal is input, the process proceeds to step SI05. Otherwise, a transfer end interrupt signal is input. Wait for it. In step SI05, parameters are set based on the production scenario configuration table and attribute data. Here, in order to form a display image in the display area A or B of the VRAM 536 based on the image data transferred to the VRAM 536 in step SI01, the CPU 504 has information on the image data constituting the display image (coordinate axis and image size of the VRAM 536). , VRAM coordinates (arrangement coordinates, etc.) are instructed to the VDP 534. The VDP 534 performs parameter setting in accordance with the attribute based on the instruction stored in the attribute register.

  In step SI07, a drawing instruction is performed. In this drawing instruction, the CPU 504 instructs the VDP 534 to start drawing an image. The VDP 534 starts drawing an image in the frame buffer in accordance with an instruction from the CPU 504.

  In step SI09, it is determined whether or not a generation end interrupt signal from the VDP 534 is input based on the end of image drawing. If the generation end interrupt signal is input, the process proceeds to step SI11. If not, the generation end interrupt signal is determined. Wait for input. In step SI11, a scene display counter which is set in a predetermined area of the RAM 508 and counts how many scene images have been generated is incremented (+1), and the process ends.

<Second embodiment>
In the configuration example of FIG. 7, the DC / DC converter 51 is provided to generate the DC voltage of 2.2 V. However, when the DC voltage of 2.2 V is not necessary, the DC / DC converter 51 can be omitted. In the configuration example of FIG. 7, the DC / DC converter 52 is provided to generate the direct-current voltage of 5.0 V. However, the direct-current voltage of 5.0 V is generated by the power supply board 600 and supplied to the sub-control board. Also good.

  FIG. 19 shows an example. In the example shown in the figure, it is assumed that the basic circuit 502 operates using a DC voltage of 3.0 V as a driving voltage, and the circuit wiring 55 is directly connected to the basic circuit 502.

  In the example of FIG. 19, a DC voltage of 5.0 V is supplied from the power supply board 600 to the connector CN9. In the example of FIG. 19, it is assumed that the connector CN7 and CN8 are supplied with a DC voltage of 5.0V, and circuit wiring for supplying a DC voltage of 5.0V is connected to these connectors. In this way, a configuration in which the DC / DC converter 52 is omitted can be employed.

<Third embodiment>
In the first embodiment, the connectors CN2 and CN3 are provided on the circuit board 40, but may be provided on the circuit board 50. FIG. 20 shows an example.

  As shown in FIG. 20A, the connector CN <b> 2 is provided on the circuit board 50, and the connector included in the circuit board 40 is only the connector 11 of the connector 10. The fan F <b> 1 is connected to the circuit board 50 by providing the connector CN <b> 3 on the circuit board 50. In the example of the figure, it is assumed that the drive voltage of the fan F1 is 24V.

  FIG. 20B shows the arrangement of the fan F1 and the harness H1 and the state before and after the circuit board 40 and the circuit board 50 are separated. The fan F1 is provided in the substrate storage case 220A as in the first embodiment. The board storage cases 220A and 220B are respectively formed with openings 224 and 223 through which the harness H1 passes, and the harness H1 is connected to the connector CN2 through the outside of the board storage case 220.

  By separating the circuit board 40 and the circuit board 50, the board storage case 220A and the board storage case 220B are separated. As a result, the harness H1 may be disconnected from the connector CN3, and connection and disconnection of the circuit board 40 and the circuit board 50 may be associated with driving and stopping of the fan F1.

  The opening 224 on the fan F1 side is positioned higher than the opening 223 on the circuit board 50 side by a height h. For this reason, when the board storage case 220A and the board storage case 220B are separated due to the separation of the circuit board 40 and the circuit board 50, the harness H1 may be easily detached from the connector CN3.

  The harness H1 may be able to suppress fraud by passing through the outside of the substrate storage case 220. That is, when an unauthorized person tries to remove the circuit board 40 or the circuit board 50, the presence of the harness H1 is easily noticeable. In order to separate the circuit board 40 and the circuit board 50, the harness H1 is removed. May be recognized as necessary, and if removed, it may become uneasy whether it can be restored. Even if it is restored, if the fan F1 is not driven, the operation of the basic circuit 402 will be impaired. If the operation of the basic circuit 402 is impaired, it will be found by a player or an attendant at a game store. It becomes easy to be done. Thereby, there is a case where cheating can be hesitant.

<Fourth embodiment>
In the first embodiment, the first sub-control unit 400 and the second sub-control unit 500 each have a CPU (CPUs 404 and 504), but may be one. FIG. 21 is a block diagram of a control unit showing an example thereof. The sub-control unit 400 ′ is obtained by integrating the first sub-control unit 400 and the second sub-control unit 500, and corresponding components are denoted by the same reference numerals.

The sub-control unit 400 ′ does not have a configuration corresponding to the VDP 516 and the VRAM 518, and includes a drive circuit 430 that drives the effect image display device 157. The functions of the VDP 516 and the VRAM 518 are realized by the CPU 404 and the RAM 408, but the VDP 516 and the VRAM 518 may be included. In addition, in the example shown in the figure, an RTC (real-time clock) 405 is added so that the basic circuit 402 can acquire information on the current time. The RTC 405 is an electronic component that functions as a watch.

  FIG. 22 shows a configuration example of the sub-control board in this embodiment. The same reference numerals are given to the same configurations as those in the first embodiment, and the circuit board 40 and the circuit board 50 are connected by the connector 10. As the configuration of the connector 10 and the configuration of the circuit wiring, those described in the first embodiment can be used as appropriate.

Other configurations of the sub-control unit 400 ′ illustrated in FIG. 21 can be appropriately distributed between the circuit board 40 and the circuit board 50, but the circuit board 40 is used in common for a plurality of models. The crystal oscillator 414 and the ROM 406 may be provided on the side, and other circuits and ICs may be provided on the circuit board 50 side, or connectors for connecting to other circuits and ICs may be provided on the circuit board 50.

DC voltage is supplied. The RTC 405 has a signal line indicated by a broken line via the connector 10 connected to the basic circuit 402, and can transmit time information. When the power is turned on, the CPU 404 of the basic circuit 402 can read the time information only once, and this time information can be used for control such as effect control.

  Note that the electronic component to which the 3.3V DC voltage is supplied from the circuit board 40 may be an electronic component such as a sound source IC or a logic IC. Further, it may be an electronic component that operates by supplying a 3.3V DC voltage from the circuit board 40 (in the case of the RTC 405, an operation that keeps ticking time), or may be supplied from the circuit board 40. It may be an electronic component that uses a DC voltage of 3V as a signal voltage to the basic circuit 402 (or a voltage that generates a time information signal if it is an RTC), or a DC voltage of 3.3V is supplied from the circuit board 40. In other words, the electronic component may be an electronic component that uses a 3.3V DC voltage supplied from the circuit board 40 as a signal voltage to the basic circuit 402.

  Each process of steps SC11 to SC15 includes a process of outputting each control data. After the shutter control process in step SC15, an image control process in step SC18 is added instead of the information output process in step SC17 in FIG. This process corresponds to the image control process of the second sub control unit 500 described with reference to FIG. 18D, and in the present embodiment, the second sub control unit 500 is not provided. This is what the CPU 402 does. FIG. 24D shows the contents of the image control process, which is the same as the image control process of FIG. However, in the present embodiment, since the VDP 534 and the VRAM 536 are not provided, these functions are executed by the CPU 402 and the RAM 408.

  The command reception interrupt process in FIG. 24B and the timer interrupt process in FIG. 24C are the same as the processes in FIG. 16B and FIG.

  FIG. 25 illustrates an initialization process executed by the CPU 402 when it is initialized by a reset signal or the like. In step SC01, the hardware is initialized, and in step SC23, the time is set. Here, the current time information is acquired from the RTC 405 and stored. This information is used for subsequent control. Thus, one unit of processing is completed.

  As the use of the subsequent control of the current time information stored in step SC23, for example, the effect content is changed based on the current time information. For example, if the current time information is information on the opening time of an amusement store, a change to add an effect at the time of opening is performed, and if information on the closing time of an amusement store is changed, the change to add an effect at the time of closing is performed. Also, for example, if the current time information is spring information, a change that adds a spring-like effect is made, and if summer information is changed, a change that adds a summer-like effect is made.

In addition, when the electrical connection between the first circuit board and the second circuit board is broken, the second voltage may not be supplied to the second electronic component. In some cases, malfunction of the control means can be prevented.
