In such a gaming machine, a main control board that controls a winning combination, a gaming value to be given, etc., a power supply board that is connected to the main control board and supplies power, and is supplied with power from the main control board to control effects. Some have a configuration in which power is supplied in series from the power supply board to the main control board and the sub control board by having the sub control board.

  However, in the above gaming machine, power is supplied from the power supply board to the main control board, and power is supplied in series from the main control board to the sub-control board, etc. As a result, the reduced voltage is supplied to the sub-control board, which may cause a malfunction in the gaming operation. For this reason, for example, as shown in Patent Document 1, the power supply board is configured to supply power in parallel to the main control board, the sub-control board, and other processing boards, and the supply voltage is reduced below a predetermined value. A gaming machine having a detector for detecting a case has been proposed.

JP 2001-198274 A

  However, since the gaming machine of Patent Document 1 detects only when the supply voltage falls below a predetermined value, for example, it cannot be detected when the supply voltage suddenly increases due to cheating or static electricity by the player. . As a result, fraudulent acts cannot be prevented, and the control board may break down due to a rapid increase in supply voltage. In addition, since this gaming machine supplies power in parallel from the power supply board to each processing board, the power supply path may be complicated and the circuit layout may be easily complicated.

  Accordingly, an object of the present invention is to provide a gaming machine capable of preventing failure, malfunction, etc. by making the supply voltage below a certain value, and further simplifying the power supply path and circuit arrangement. It is to be.

  In order to achieve the above object, the present invention provides a symbol display means capable of variably displaying a plurality of symbols, and from the start to the stop of the symbol variation display on the symbol display means while supplying power to the symbol display means. A main control means for controlling the state and executing a game for giving a game value based on the symbol after the stop, an effect means for producing the game, and a sub-control means for controlling the effect while supplying power to the effect means Power supply means for supplying power to the main control means and the sub control means, respectively, and at least on the input side of the power supplied to the main control means and the sub control means, and the power voltage is limited to a predetermined voltage or less. Drive voltage limiting means.

  According to this configuration, even if a go-to action that causes the main control means or the sub-control means to malfunction by forcibly applying a high voltage from the outside on the output side of the power supply means is performed, the drive voltage limiting means By limiting the high voltage to a predetermined voltage or less, there may be cases where at least the main control means and the sub-control means can prevent a go-to action caused by malfunctioning at the high voltage. Further, in addition to such a go-to action, it may be possible to prevent malfunction due to the occurrence of a surge voltage due to static electricity.

  Further, since power is supplied from the power supply means to the main control means and the sub control means, respectively, for example, when power is supplied from the power supply means to the sub control means via the main control means, Electric power is not supplied to the sub-control means in a state where the voltage is lowered due to the voltage drop. Thereby, even when the voltage of the electric power output from the power supply means to the main control means and the sub control means is lowered, the sub control means and the effect means supplied with power from the sub control means can be operated reliably. There is a case. In addition, if the voltage is lowered, the power consumption of each means such as the main control means and the sub-control means can be suppressed, so that the heat generation due to power consumption is suppressed and the malfunction of each means due to heat is prevented. In some cases, the running cost can be reduced. Furthermore, a power supply path is constructed in which power is supplied from the power supply means to the main control means and the sub control means, respectively, and power is supplied from the main control means to the symbol display means, and power is supplied from the sub control means to the effect means. Therefore, there are cases where the wiring and circuit arrangement can be simplified as compared with the case of the power supply path for supplying power from the power supply means to all the means.

  The present invention also includes drive current limiting means that is provided at least on the input side of the power supplied to the main control means and the sub control means, and limits the current of the power to a predetermined current or less. According to this configuration, power is supplied to the main control means and the sub-control means at a current equal to or lower than a predetermined current, so that it may be possible to more reliably prevent malfunctions due to goto action or static electricity.

  Furthermore, it is preferable that at least one of the drive voltage limiting means and the drive current limiting means of the present invention is also provided on the power output side of the main control means and the sub control means. According to this, it may be possible to prevent malfunction of the symbol display means and the rendering means supplied with power from the main control means and the sub control means.

  Further, the present invention may be configured to include power supply voltage limiting means that is provided on the input side of the power supply means and limits the voltage of power supplied to the power supply means to a predetermined voltage or less. According to this configuration, it may be possible to prevent malfunctions of the main control means and the sub-control means due to malfunction of the power supply means.

  Further, in the power supply means of the present invention, the power supplied to the main control means and the sub control means may be set to the same voltage of 12V. According to this configuration, the same voltage of 12 V is supplied to the main control unit and the sub control unit, respectively, so that the circuit configuration of the power supply unit may be simplified. Furthermore, the circuit element may be prevented from being deteriorated as compared with the case where power is supplied at a voltage of 24V. Further, in the case of 12V driving, the main control means and the sub control means are more likely to malfunction due to voltage fluctuation than in the case of 24V, but at least excessive voltage fluctuation is prevented by the driving voltage limiting means. In some cases, it is possible to sufficiently prevent malfunction due to variation in transformation.

Specifically, the power supply board 61 is a wiring composed of a DC 12V voltage line and a voltage line for supplying the voltage Vram for the RAMs 33 and 76 of the main control board 71 and the sub control board 73, and the main control board 71 and the sub control board. It is connected to the substrate 73. In addition, by providing a voltage line for supplying the voltage Vram, the contents stored in the RAMs 33 and 76 can be prevented from being erased. Further, although not shown in FIG. 14, the power supply board 61 is further connected to the external concentration terminal plate 42 through a DC 12 V voltage line.

  As shown in FIG. 14, the power supply board 61 is connected to a power supply 65 and supplied with a voltage of AC 100V. The power supply board 61 supplies a DC 12V voltage to the connected main control board 71, sub-control board 73, and external concentration terminal board 42. Specifically, the power supply board 61 has a main power supply part 61A and a sub power supply part 61B. The main power supply part 61A supplies power to the main control board 71 and the external concentrated terminal board 42, and the sub power supply. The unit 61B supplies power to the sub control board 73. The power supply board 61 is connected to a power supply main switch 66, and the operation of the power supply board 61 can be stopped by turning off the power supply main switch 66. In addition, the door relay board 70 and the reel board 47, which are other boards, are connected to the main control board 71 by voltage lines as described above, and voltage is supplied from the main control board 71. Yes. In FIG. 14, the main control board 71 and the sub control board 73 are connected to the terminals of the power supply board 61, but the connection terminals may be separated. In this case, wiring is simplified.

  In this way, when power is supplied from the power supply board 61 to the main control board 71 and the sub control board 73, for example, power is supplied from the power supply board 61 to the sub control board 73 via the main control board 71. As described above, the voltage is not supplied to the sub control board 73 in a state where the voltage is lowered due to the voltage drop in the main control board 71. As a result, even when the voltage of power output from the power supply board 61 to the main control board 71 and the sub control board 73 is changed from 24 V to 12 V, power is supplied from the sub control board 73 and the sub control board 73. The liquid crystal display device 5 and the like can be reliably operated. Further, if the voltage is lowered, the power consumption of the main control board 71, the sub control board 73, etc. can be suppressed, so that the heat generation due to the power consumption is suppressed and the malfunction of each board due to the heat is prevented. In some cases, the running cost can be reduced.

  Furthermore, power is supplied from the power supply board 61 to the main control board 71 and the sub control board 73 respectively, and power is supplied from the main control board 71 to the symbol display means, and power is supplied from the sub control board 73 to the effect means. Since the power supply path is configured, there are cases where the wiring and circuit arrangement can be simplified as compared with the case of the power supply path for supplying power from the power supply board 61 to all means.

  Further, by dividing the power supply board 61 into the main power supply section 61A and the sub power supply section 61B, when designing the circuit of the power supply board 61, the optimum power supply according to each power consumption of the main control board 71 and the sub control board 73 is obtained. Since a component can be selected, there is a case where it is possible to achieve a long life while suppressing an increase in the component cost of the power supply board 61.

  Further, as shown in FIG. 15A, a tuner diode 84A and a resistor 84B are connected in series on the power supply path, specifically, on the input side of each board to which power is supplied. A voltage limiter 84 (drive voltage limiting means) is provided. When the applied voltage is in the reverse direction, the Zener diode 84A is in a breakdown state at a specific voltage, and exhibits a substantially constant voltage even if the current fluctuates. Note that the value of the resistor 84B is determined by the voltage applied to the voltage limiter 84, the constant voltage (12V in this embodiment) and current desired to be obtained by the tuner diode 84A. Thereby, it is possible to prevent the voltage passing through the voltage limiter 84 from exceeding a certain value. As a result, for example, even when the voltage suddenly increases due to goto action (tampering), static electricity, etc., it is possible to prevent a voltage exceeding a certain value from flowing and prevent malfunction or failure. be able to.

  The voltage limiter 84 is provided on the input side of each board to which power is supplied, but may be provided on the output side of each board. Further, a current limiter 85 (driving current limiting means) for limiting the current value may be further provided in the vicinity of the voltage limiter 84 to further prevent malfunction. That is, as shown in FIG. 15B, a current limiter 85 in which a constant current diode (CRD) 85A and a resistor 85B are connected in series is set in the middle of a path through which power is supplied. May be provided on the input side of each board to which power is supplied. The constant current diode 85A is an element having a characteristic of supplying a constant current from a low voltage to a high voltage. Also in this case, it becomes possible to prevent malfunction of the rotating reels 3L, 3C, 3R, the liquid crystal display device 5 and the like to which power is supplied from the main control board 71 and the sub control board 73. The voltage limiter 84 may be provided as a power supply voltage limiting means on the input side of the power supply board 61, that is, on the power supply path between the power supply board 61 and the power supply 65. In this case, malfunctions of the main control board 71 and the sub control board 73 caused by malfunction of the power supply board 61 can also be prevented.

  The gaming machine 1 configured as described above has five types of games consisting of “general gaming state”, “BB internal winning state”, “RB internal winning state”, “BB general gaming state”, and “RB gaming state”. Make a state appear. Each of these “five types” gaming states is basically distinguished by the type of winning combination that may be won internally, the type of bonus that can be achieved, and the relationship between internal winning and winning. The In the present embodiment, a bonus carried over when a predetermined number of games are played can be won, but the present invention is not limited to this, and can be set as appropriate. In this embodiment, in the general gaming state and the internal winning state, the bonus is held as a winning combination after the bonus is won internally until the bonus winning is established (generally, “carryover”, “carryover state”). ).

  Here, the BB game state, which is triggered by the establishment of a BB prize and is constituted by the “BB general game state” and the “RB game state”, is hereinafter collectively referred to as “BB game state”. Further, “BB internal winning state” and “RB internal winning state” are states in which a bonus is internally won, and these are collectively referred to as “internally winning state” hereinafter. The “internal winning state” includes a state where a bonus is carried over.

  BB's winning is established when "blue 7-blue 7-blue 7" or "red 7-red 7-red 7" are lined up along the active line in the "internal winning state" and wins 15 medals. can do. More specifically, “transparent 7-transparent 7-transparent 7” is arranged, and the LED lamp 29 changes to “blue 7-blue 7-blue 7” or “red 7-red 7-red 7”. After the BB winning is established, the gaming state becomes the “BB general gaming state”.

  In addition, in the RB winning combination, “Red 7-Red 7-Blue 7” is arranged along the active line in “Internal winning state”, or “Replay-Replay-Replay” is arranged in “BB general gaming state”. In any case, 15 medals can be obtained. The establishment of RB winning in the BB general gaming state is generally referred to as “JACIN”. After the RB winning is established, the gaming state becomes the RB gaming state.

  It should be noted that bonus winning is not established in a game in which a bonus (excluding “JACIN”) is won internally regardless of the gaming state. Further, when the bonus is internally won in the general gaming state, the game is shifted to another gaming state in the next game. Therefore, no bonus winning is established in the general gaming state.

  The replay winning is established by arranging “Replay-Replay-Replay” in the general gaming state and the internal winning state. When a re-game winning is established, the same number of medals as the number of inserted medals are automatically inserted, so that the player can play the next game without consuming the medals.

  In addition, in the general gaming state and the BB general gaming state, the winning establishment of “upper chile small part”, “lower chile small part”, “bell small part”, and “watermelon small part” shall be realized. Is possible.

  The winning combination of winnings is established by arranging “Replay-Replay-Replay”, “Red 7-Replay-Replay” and “Blue 7-Replay-Replay” in the RB gaming state. When the number of winning winnings of the bonus becomes “8”, or when 12 games are completed, the gaming state shifts. Here, a game in an RB gaming state in which a winning combination of winnings may be established is generally referred to as a “JAC game”.

  In the above configuration, the operation of the gaming machine will be described. As shown in FIG. 14, when the power supply main switch 66 is operated at the start of work or maintenance, commercial or household AC power such as AC 100 V is supplied to the power supply board 61 via the plug of the power supply 65. The This AC power is rectified and smoothed by the power supply substrate 61 and converted to 12V DC power. Then, the DC power of 12 V is supplied from the power supply board 61 to the main control board 71 and the sub control board 73, and is used as driving power for both boards 71 and 73. Further, the external concentrated terminal board 42 is also supplied with 12V DC power from the power supply board 61 and used as driving power for the external concentrated terminal board 42.

  As a result, DC power of 12V is supplied in parallel from the power supply board 61 to the control boards 71 and 73 and the external concentrated terminal board 42, so that power is supplied from the power supply board 61 via the main control board 71. In addition, DC power is not supplied to the sub-control means 73 or the external concentrated terminal board 42 in a state where the voltage is lowered due to the voltage drop in the main control means 71. As a result, even when the voltage of the DC power output from the power supply board 61 to the main control board 71 and the sub control board 73 is lowered to a state close to the rated voltage of the lamp used for production, such as 12V, it is sufficient. The lamp can be turned on with luminance, and the sub-control board 73 and the liquid crystal display device 5 to which power is supplied from the sub-control board 73 can be operated reliably. In addition, the DC power is supplied to the external concentration terminal plate 42 in a state where the voltage is lowered, the external concentration terminal plate 42 cannot be operated reliably, and the hall computer cannot receive the signal, and the gaming machine 1 has a problem. It is possible to reduce mistakenly judging that it has occurred. Furthermore, by suppressing the voltage to 12 V, the power consumption of each board such as the main control board 71, the sub control board 73, the external concentration terminal board 42, and the like can be suppressed, so that heat generation due to power consumption is suppressed. In addition, it is possible to prevent malfunction of the electronic circuit of each substrate due to heat, and to reduce running cost.

  When power is supplied in parallel from the power supply board 61 to the main control board 71, the sub control board 73, and the external concentration terminal board 42 as described above, the game is stabilized on the main control board 71 without malfunction. In the sub control board 73, the effect is stably executed without malfunctioning based on various game information such as the game state and the internal winning combination inputted from the main control board 71. Further, the external concentrated terminal board 42 can be surely communicated with the hall computer. Hereinafter, a game executed on the main control board 71 and an effect executed on the sub-control board 73 will be described in detail.

  First, the control operation of the CPU 31 of the main control board 71 will be described with reference to the main flowchart shown in FIG. First, the CPU 31 performs initialization at the start of the game (step [hereinafter referred to as S] 1). Specifically, the storage contents of the RAM 33 are initialized, the communication data is initialized, and the like. Subsequently, the predetermined stored contents of the RAM 33 at the end of the game are deleted (S2). Specifically, the data in the writable area of the RAM 33 used for the previous game is erased, the parameters necessary for the next game are written in the write area of the RAM 33, the start address of the sequence program for the next game, etc. To do. Next, the CPU 31 stands by until a medal is inserted into the medal slot 22 or an input is made from the BET buttons 11 and 12 (S3). Thereafter, it is determined whether or not the start lever 6 has been operated (S4).

  If the start lever 6 is not operated (S4: NO), the process waits for input by repeating S4. If the start lever 6 is operated (S4: YES), a random number for lottery is used. Extract (S5). And the game state in this game is confirmed by performing a game state monitoring process (S6). That is, the game state of the current game is set to any one of the BB general game state, the RB game state, the RB internal winning state, the BB internal winning state, and the general game state.

  Then, a probability lottery process is performed (S7), and an internal winning combination is determined based on a lottery table or the like. When the internal winning combination is determined, the internal winning combination is transmitted to the sub control board 73. Subsequently, stop table group selection processing is executed (S8). Specifically, a specific stop table group is selected using the type of internal winning combination. Such a stop table group is used when the reels 3L, 3C, and 3R are stopped in the subsequent S10. Here, a game start signal including information related to the internal winning combination, the game state, and the stop table group is transmitted to the sub control board 73. Subsequently, reel rotation processing is performed (S9). Specifically, the reels 3L, 3C, and 3R are rotated, and a reel stop permission signal is transmitted to the sub control board 73 when a predetermined speed (for example, constant speed rotation) is reached.

  Next, a reel rotation stop process is executed (S10). That is, the sliding frame number determination process for determining the number of sliding frames is performed at the timing when any one of the stop buttons 7L, 7C, and 7R is operated or when the value of the automatic stop timer becomes “0”. Specifically, the number of sliding symbols is determined based on the stop table, stop operation position, and stop control position determined (selected) in S9. “The number of sliding symbols” is the number of symbols that move until the reel stops after the stop button is operated (shows the amount of movement (movement distance) of the symbol until the reel stops) . Subsequently, the reel corresponding to the stop button for which the stop operation has been performed is rotated by the number of sliding frames and then stopped. Note that each time the stop button 7L, 7C, or 7R is operated and the corresponding reel is stopped, a reel stop signal (left, middle, right) is transmitted to the sub-control board 73. Further, when all the reels are stopped, an all reel stop signal is transmitted to the sub control board 73.

  Next, the CPU 31 makes a winning determination (S11). In the winning determination, a winning combination (a winning combination) is identified based on a stop pattern of nine symbols of the rotating reel that can be visually recognized through the transmissive liquid crystal panel 54. Specifically, a winning combination is identified based on a code number of symbols arranged along the center line 8c and a winning determination table. Then, a winning signal is transmitted to the sub control board 73. Thereafter, the acquired medal is credited or paid out (S12). Specifically, when a medal is acquired by winning, a payout display unit 18 displays the number of acquired medals. Then, by switching the C / P button 14, the player can select whether to credit the acquired medal into the gaming machine 1 or pay out the medal from the medal payout exit 15. The credited medal can bet by pressing the BET buttons 11 and 12 in the next game. When it is determined that the winning combination is BB or RB, the BB or RB gaming state is generated.

  Next, it is determined whether or not the current gaming state is “BB general gaming state” or “RB gaming state” (S13). If the gaming state is not “BB general gaming state” or “RB gaming state” (S13: NO), the process returns to S2. If the game state is “BB general game state” or “RB game state” (S13: YES), “game number check process” of bonus (BB, RB) is performed (S14). In this “game number check process”, the number of times the RB gaming state has occurred, the number of games in the BB general gaming state, the number of winnings in the RB gaming state, and the number of games in the RB gaming state are checked, and the BB general gaming state and RB Transition (set) of gaming state between gaming states is performed.

  Next, it is determined whether or not the bonus is over (S15). Specifically, after the BB winning is established, whether the number of wins is 8 or the number of games is 12 in the third RB gaming state, or is the number of games is 30 in the BB general gaming state Determine whether or not. In addition, after “RB7-Red 7-Blue 7” is arranged along the active line, after the RB winning is established, whether or not the number of winnings is 8 times or the number of games is 12 times in the RB gaming state. Is determined. As a result, when it is determined that the bonus is not finished (S15: NO), the process returns to S2. On the other hand, if it is determined that the bonus has ended (S15: YES), a bonus end signal is output to the sub-control board 73 (S16), and the process returns to S2.

  As described above, the sub CPU 74 of the sub control board 73 to which various signals are transmitted from the main control board 71 when the main routine of FIG. The operation shown in the flow is being executed.

  That is, as shown in FIG. 17, when the power is turned on to the sub control board 73, the sub CPU 74 independently executes an operation of periodically setting a VDP (Video Display Processor) flag and a timer flag. Then, the sub CPU 74 executes various processing operations at operation timings using these flags, and causes the liquid crystal display device 5 to display a desired moving image or still image.

  Specifically, first, when the power is turned on, the work RAM 76 and the image control work RAM 83 are cleared and initialized (S101), and then command processing is executed (S102). In the command processing, as shown in FIG. 18, the state of the strobe signal transmitted from the main control board 71 is monitored (S201). If the strobe signal does not rise (S201: NO), this routine ends. On the other hand, when the strobe signal rises (S201: YES), a signal transmitted in parallel with the strobe signal is taken with the rise as a trigger. Then, the command content included in this signal is read (S202), and various processes such as medal insertion processing corresponding to the command content are executed to prepare a mode to be displayed on the liquid crystal display device 5 by designating an address or the like. To do.

  Next, as shown in FIG. 17, it is determined whether or not the buffer secured in the work RAM 76 is ready for image data to be transferred to the image control work RAM 83 (S103). If it is in the state (S103: YES), it is determined whether or not the timer flag is on (S106). If the timer flag is not on (S106: NO), the process is re-executed from S102 until the buffer image data is transferred to the image control work RAM 83 for use on the image control IC 82 side. Wait for the update process.

  If it is determined that the image data to be transferred to the image control work RAM 83 is not ready in the buffer (S103: NO), the data is updated so that the display mode prepared in the processing of S102 is obtained ( S104). Thereafter, the updated image data is written in the buffer (S105), and it is determined whether the timer flag that is turned on at a cycle of 1000/60 ms is on (S106), with a cycle with a certain accuracy. The mode of display on the liquid crystal display device 5 is switched.

  As a result of setting the timer flag at the interrupt timing of 1000/60 ms in the sub CPU 74 (S152), when the timer flag is turned on (S106: YES), by subsequently determining whether or not the VDP flag is turned on, It is determined whether or not the image control IC 82 is in an operable state (S107). If the VDP flag is not in the on state (S107: NO), it is determined that the VDP (= image control IC 82) is in the busy state, and the process is re-executed from S102, thereby waiting until the VDP flag is switched to the on state. On the other hand, if the VDP flag is turned on as a result of the VDP flag being set by an interrupt signal from the VDP due to the transition of the VDP (= image control IC 82) to the idle state (S151: YES) The timer flag is reset (S108), and the VDP flag is reset (S109). Thus, until the timer flag and the VDP flag are set in the next interrupt processing (S151 and S152), the image data of the image control work RAM 83 generated by the transfer from the buffer to be performed (S113), or the VDP The bank to be switched by bank switching (S112) is not updated.

  Next, in order to select whether to perform a process of alternately switching two data areas (banks) secured in the video RAM 87 or a process of transferring image data to the image control work RAM 83. The bank flag is switched on / off to a value opposite to the current bank flag. That is, the bank flag is inverted (S110), and it is determined whether the inverted bank flag is in an on state (S111). If it is on (S111: YES), the VDP (= image control IC 82) is instructed to switch to the other bank (S112), and the display image is switched. Specifically, the VRAM includes two data areas, bank 0 and bank 1, and the bank 0 displays the image corresponding to the stored image data to the player as to the control state of each bank before switching. The bank 1 is ready to store image data that has been prepared from 1000/60 ms before, and is waiting in a state where it can be displayed to the player. Next, the VDP that received the bank switching instruction makes the image corresponding to the image data stored in the bank 0 currently displayed to the player invisible to the player and already displayed to the player. Conversion control is performed so that an image corresponding to the image data stored in the bank 1 that has been prepared is displayed to the player. Thereafter, the processing from S102 is executed again.

  If the bank flag is not on (S111: NO), the image data stored in the buffer of the work RAM 76 is transferred to the image control work RAM 83 (S113). The image control IC 82 stores the image data of the image work RAM 83 transferred under the control of the sub CPU 74 in a bank different from the bank storing the image data corresponding to the currently displayed image. The image corresponding to the stored image data is displayed to the player by bank switching performed after 1000/60 ms. Thus, flickering of the screen display in the liquid crystal display device 5 is prevented by alternately storing the image data and switching the VDP bank every 1000/60 ms. Thereafter, the buffer is cleared (S114), and the process is re-executed from S102. Then, by repeatedly executing such processing from S102 to S114 using the VDP flag, timer flag, etc., an image such as a moving image or a still image corresponding to the command processing of S102 is displayed on the liquid crystal display device 5. .

  During the above operation, game information (for example, medal insertion or BB winning) signal or the like is transmitted from the main control board 71 to the external concentration terminal board 42. The external concentration terminal board 42 operates when power is supplied from the power supply board 61. As described above, the signal from the main control board 71 is transmitted to the hall computer via the relay of the external concentration terminal board 42, and when the power is supplied, the contact portion of the relay Is closed and a signal can be transmitted. For example, when a medal is inserted into the medal insertion slot 22 of the gaming machine 1, a detection signal is transmitted from the medal insertion switch 22A to the main control board 71, and further transmitted from the main control board 71 to the external concentration terminal board 42. . When the external concentration terminal board 42 receives such a signal, it transmits it to the hall computer. Thereby, the hall computer side can determine that the gaming machine 1 is operating normally by receiving a signal from the external concentration terminal board 42. In addition, if the hall computer does not receive a signal from the external concentration terminal board 42 for a certain period of time, there is a possibility that a problem has occurred in the power supply board 61 or the main control board 71 of the gaming machine 1 having the external concentration terminal board 42. Since it is expensive, it is possible to deal with problems and the like more quickly.

  As described above, when the game and effects are repeatedly performed by executing the main routine and the like in FIG. 16, a high voltage is forcibly applied from the outside on the output side of the power supply board 61 as shown in FIG. When the giving action is performed, the voltage limiter 84 limits the high voltage to a predetermined voltage and a predetermined current before the high voltage is applied to the main control board 71 and the sub control board 73. Specifically, as shown in FIG. 15, when a high voltage is applied, the tuner diode 84A of the voltage limiter 84 limits the predetermined voltage to a predetermined voltage, and the power of the limited predetermined voltage is supplied to the main control board 71 and the sub control board. 73. In the case where the current limiter 85 is provided, when a high current is applied, the constant current diode 85A of the current limiter 85 limits to a predetermined current, and the power of the limited predetermined current is supplied to the main control board 71. And supplied to the sub-control board 73. As a result, the high voltage is limited to a predetermined voltage or less by the voltage limiter 84 or the current limiter 85, and the high current is limited to the predetermined current or less, whereby the main control board 71 and the sub control board 73 are set to the high voltage. In addition, goto action caused by malfunction at high current is prevented. Further, in addition to such a goat action, malfunction due to the occurrence of a surge voltage due to static electricity is also prevented.

  In addition, when the game and effects are repeatedly performed as described above and the power supply board 61 needs to be updated, the power supply box 60 is opened as shown in FIG. Then, as shown in FIG. 7, for example, when the main power supply unit 61A is an update target, the blocked main power supply unit 61A is removed from the socket 61S and replaced with a new main power supply unit 61A. It is done. At this time, the main power supply unit 61A and the sub power supply unit 61B can be distinguished from each other, that is, for example, the main power supply unit 61A is colored blue and the sub power supply unit 61B is colored red. Accordingly, it is possible to prevent mistakes from the sub power supply unit 61B during the update operation of the main power supply unit 61A, and thus it is possible to prevent a delay in the update operation due to a work error. Such prevention of the handling of the main power supply unit 61A and the sub power supply unit 61B is also effective when the power supply board 61 is manufactured.

  As described above, the present embodiment includes a symbol display means (for example, rotating reels 3L, 3C, and 3R) capable of variably displaying a plurality of symbols, and the symbol display means while supplying power to the symbol display means. The main control means (for example, the main control board 71) for controlling the state from the start to the stop of the symbol variation display and stopping the game based on the symbol after the stop, and the effect of producing the game Power is supplied to the means (for example, the liquid crystal display device 5), the sub-control means (for example, the sub-control board 73) that controls the effect while supplying power to the effect means, and the main control means and the sub-control means. Drive voltage limiting means (for example, a power supply board 61) and a drive voltage limiting means (for example, provided on the input side of power supplied to at least the main control means and the sub control means, respectively, for limiting the power voltage to a predetermined voltage or less. If has a voltage limit 84) and.

  According to this configuration, even if a go-to action that causes the main control means or the sub-control means to malfunction by forcibly applying a high voltage from the outside on the output side of the power supply means is performed, the drive voltage limiting means By limiting the high voltage to a predetermined voltage or less, there may be cases where at least the main control means and the sub-control means can prevent a go-to action caused by malfunctioning at the high voltage. Further, in addition to such a go-to action, it may be possible to prevent malfunction due to the occurrence of a surge voltage due to static electricity.

  Further, since power is supplied from the power supply means to the main control means and the sub control means, respectively, for example, when power is supplied from the power supply means to the sub control means via the main control means, Electric power is not supplied to the sub-control means in a state where the voltage is lowered due to the voltage drop. Thereby, even when the voltage of the electric power output from the power supply means to the main control means and the sub control means is lowered, the sub control means and the effect means supplied with power from the sub control means can be operated reliably. There is a case. In addition, if the voltage is lowered, the power consumption of each means such as the main control means and the sub-control means can be suppressed, so that the heat generation due to power consumption is suppressed and the malfunction of each means due to heat is prevented. In some cases, the running cost can be reduced. Furthermore, a power supply path is constructed in which power is supplied from the power supply means to the main control means and the sub control means, respectively, and power is supplied from the main control means to the symbol display means, and power is supplied from the sub control means to the effect means. Therefore, there are cases where the wiring and circuit arrangement can be simplified as compared with the case of the power supply path for supplying power from the power supply means to all the means.

  Further, the present embodiment is provided at least on the input side of the power supplied to the main control means and the sub-control means, respectively, and driving current limiting means (for example, current limiter 85) that limits the current of the power to a predetermined current or less. )have. According to this configuration, power is supplied to the main control means and the sub-control means at a current equal to or lower than a predetermined current, so that it may be possible to more reliably prevent malfunctions due to goto action or static electricity.

  Furthermore, it is preferable that at least one of the drive voltage limiting unit and the drive current limiting unit of the present embodiment is also provided on the power output side of the main control unit and the sub control unit. According to this, it may be possible to prevent malfunction of the symbol display means and the rendering means supplied with power from the main control means and the sub control means.

  In addition, the present embodiment is configured to include power supply voltage limiting means (for example, voltage limiter 84) that is provided on the input side of the power supply means and limits the voltage of power supplied to the power supply means to a predetermined voltage or less. There may be. According to this configuration, it may be possible to prevent malfunctions of the main control means and the sub-control means due to malfunction of the power supply means.

  Further, in the power supply means of the present invention, the power supplied to the main control means and the sub control means may be set to the same voltage of 12V. According to this configuration, the same voltage of 12 V is supplied to the main control unit and the sub control unit, respectively, so that the circuit configuration of the power supply unit may be simplified. Furthermore, the circuit element may be prevented from being deteriorated as compared with the case where power is supplied at a voltage of 24V. Further, in the case of 12V driving, the main control means and the sub control means are more likely to malfunction due to voltage fluctuation than in the case of 24V, but at least excessive voltage fluctuation is prevented by the driving voltage limiting means. In some cases, it is possible to sufficiently prevent malfunction due to variation in transformation.

  As mentioned above, although the Example of this invention was described, it has only illustrated the specific example and does not specifically limit this invention. That is, in the present embodiment, each board constituting the gaming machine 1 has been specifically described, but is not limited as described above. For example, the door relay board 70 and the reel board 47 may be configured on the same board. In addition, the power supply monitoring unit 82 of the present embodiment is composed of a chenner diode and a resistor, but it may be composed of another element, and the voltage limit value may not be 12V. In the present embodiment, power may be directly supplied from the power supply board 61 to the external concentration terminal board 42.

  The power supply board 61 has a main power supply part 61A and a sub power supply part 61B, and supplies power to the main control board 71 and the sub control board 71 separately. You may make it do. In this embodiment, the gaming machine is described as a pachislot machine, but it goes without saying that the gaming machine may be a pachinko machine or other gaming machines.
