JP, 2003-299860, A It aims at operation compensation to what needs operation compensation when a power supply falls to a predetermined voltage. DC32V is supplied from the DC32V converter and DC12V is supplied from the DC12V converter to a launch motor that does not need to compensate for the operation when the power is shut off. On the other hand, for various sensors that need to compensate for the operation when the power is shut down, a large prize opening solenoid, a normal electric accessory solenoid, a microprocessor, etc., it operates in various parts of the DC32V conversion unit, DC12V conversion / DC5V conversion unit different from the above A compensation capacitor is provided to supply power to each device. JP, 2002-85659, A Noise filter circuit is provided in the 5V line supplied to a main board. A capacitor is disposed between the input and ground of the noise filter circuit and between the output and ground, and a double L-type noise elimination circuit is formed by the capacitor and the noise filter circuit. Furthermore, a voltage stabilizing capacitor is arranged between the signal line and the ground level in the subsequent stage of the double L-type noise elimination circuit. If comprised in this way, it will become possible to reduce noise effectively.

  In recent gaming machines, it is provided with more actuating equipment including a movable part and a drive part (motor, solenoid) for driving the movable part, and more light emitting elements (LEDs) for blinking light related to the effect. It is becoming. Although current is supplied from the power supply unit to these devices for effects such as an accessory device and a light emitting element, the current consumption is reduced by adding a drive unit such as a motor of the accessory device and an LED of the light emitting element. It will increase.

  The gaming machine before it has more drive units and light-emitting elements is designed assuming the number of existing drive units and light-emitting elements, and its power supply unit is based on the existing drive units and light-emitting elements.

  Further, as shown in FIG. 2, a lead-out path 136 that covers the lower side and communicates with the payout port 135 of the front door 130 is provided below the medal selector 1. The medals distributed by the medal selector 1 are returned to the player from the payout port 135 via the derivation path 136.

FIG. 3 shows a functional block diagram of the slot machine 100 according to the embodiment of the invention.
The slot machine 100 includes a main substrate 10 and a sub substrate 20 that operates in response to a command from the main substrate 10 as main processing devices. At least the main substrate 10 is accommodated inside the case so that it cannot be contacted from the outside, and is sealed so that traces remain when these substrates are removed. The power supply unit 205 supplies current to at least the main board 10, the sub board 20, and the peripheral board connected to the sub board 20 (see FIG. 5).

  The main board 10 is for performing an internal lottery in response to a player's operation, and processing such as reel rotation / stop and medal payout. The main board 10 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub board 20 is for receiving a command signal from the main board 10 and notifying the result of the internal lottery and performing various effects. The sub-board 20 includes a CPU that performs a control operation in accordance with a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like. Only one command flows from the main board 10 to the sub board 20, and conversely, no command is issued from the sub board 20 to the main board 10.

  The main board 10 counts the start switch 134, the stop button 140, the reel unit (including the reel driving device) 203, the reel position detection circuit 71, the hopper driving unit 80, the hopper 81, and the number of medals paid out from the hopper 81. For this purpose, a medal detection unit 82 (which constitutes the hopper device 121 described above) is connected.

  The hopper driving unit 80 rotates the hopper 81 and performs an operation of paying out medals of the payout number instructed by the main board 10. The gaming machine includes a medal detection unit 82 that operates every time a medal is paid out, and the main board 10 receives a medal actually paid out from the hopper 81 based on an input signal from the medal detection unit 82. You can manage the number.

  Further, medal sensors S1 and S2 of the medal selector 1 are connected to the main board 10.

  The medal selector 1 is provided with medal sensors S1 and S2 for counting medals. The medal sensors S1 and S2 are provided on the downstream side (near the exit) of a medal passage (not shown) provided in the medal selector 1 (the upstream side of the medal passage communicates with the medal slot 132). The two medal sensors S1 and S2 are arranged side by side at a predetermined interval along the medal traveling direction. The medal sensors S1 and S2 are, for example, photointerrupters that have a light emitting portion and a light receiving portion that face each other, are formed in a U-shaped cross section, and are positioned so that the detection optical axis faces the medal passage from above. . Each photo interrupter detects the passage of a medal sent without being blocked on the way. The reason why two photo interrupters are adjacent is not only to detect the number of medals but also to monitor whether or not the passage of medals is normal. That is, by providing two photo interrupters adjacent to each other, it is possible to detect the passing speed and passing direction of medals, thereby detecting not only the number of medals but also an illegal act moving in the reverse direction.

  A peripheral substrate (local substrate) such as a liquid crystal control substrate 200 for controlling the liquid crystal display device, a speaker substrate 201, and an LED substrate 202 is connected to the sub substrate 20 (the liquid crystal control substrate 200 and the speaker substrate 201 are the sub substrate 20). Some are provided on top of each other). Furthermore, movable bodies 50 and 50 '(including motors 50M and 50'M and sensors 57 and 57') are connected.

  The main board 10 receives the outputs of the medal sensors S1 and S2 of the medal selector 1, accepts the insertion of medals for each game, and based on the fact that medals corresponding to the prescribed number of insertions are inserted, A process of permitting the rotation start operation of the first reel to the third reel is performed (input acceptance function). Note that the pressing operation of the start switch 134 is an opportunity to start rotation of the first reel to the third reel and an opportunity to execute the internal lottery. Also, a prescribed number of throws is set according to the gaming state, the prescribed number of throws is set to 3 in the normal state and the bonus established state, and the prescribed number of throws is set to 1 in the bonus state.

  When medals are inserted, the inserted medals are set to the inserted state up to a specified number of insertions according to the gaming state. Alternatively, when the bet switch BET is pressed in a state where medals have been credited to the gaming machine, the credited medals are set to the inserted state by limiting the prescribed number of insertions according to the gaming state. The main board 10 controls whether or not to accept a medal. When it is not in a state of accepting insertion of medals (when not permitted), even if medals are inserted, they are not counted by the medal sensors S1 and S2 and are returned as they are. Similarly, the main board 10 controls the validity / invalidity of the bet switch BET. When the bet switch BET is not valid (when not permitted), even if the bet switch BET is pressed, it is ignored.

  The main board 10 incorporates random number generating means (not shown). The random number generating means is means for generating a random number value for lottery. The random value can be generated based on, for example, a count value of an increment counter (a counter that counts a numerical value so as to circulate a predetermined count range). In this embodiment, the “random number value” is not only a value that is randomly generated in a mathematical sense, but even if the generation itself is regular, the acquisition timing and the like are irregular. Includes a value that can function as a random number.

  The main board 10 performs an internal lottery (internal lottery function) in which the player determines whether or not the winning combination is based on a start signal from the start switch 134. That is, lottery table selection processing, random number determination processing, lottery flag setting processing, and the like are performed.

  In the lottery table selection process, a lottery table (not shown) stored in a storage unit (ROM) (not shown) is used to determine which lottery table is used for internal lottery. In the lottery table, for each of a plurality of random values (for example, 65536 random values from 0 to 65535), replay, small role (bell, cherry), regular bonus (RB: bonus), and big bonus (BB :), etc., are associated with each other. In addition, a normal state, a bonus establishment state, and a bonus state can be set as the gaming state, and a replay lottery state, a replay low probability state, and a replay high probability state can be set as replay lottery states.

  In the random number determination process, a random value (lottery random number) is acquired from the random number generation means (not shown) for each game based on a start signal from the start switch 134, and the lottery table is referred to for the acquired random value. Then, it is determined whether or not the winning combination is won.

  In the lottery flag setting process, the lottery flag of the winning combination determined to be won based on the result of the random number determination process is changed from the non-winning state (first flag state, off state) to the winning state (second flag state, on Status). When two or more types of winning combinations are won, a lottery flag corresponding to each of the two or more types of winning winning combinations is set to the winning state. The lottery flag setting information is stored in storage means (RAM).

  A lottery flag (possible carryover flag) that can carry over the winning state for the next game until winning, and a lottery flag that is reset to the non-winning state without bringing the winning state to the next game regardless of winning Carry-over impossible flag) may be provided. In this case, there are a regular bonus (RB) and a big bonus (BB) as a combination to which the former carry-over possible flag is associated, and other combinations (for example, small role, replay) correspond to the latter carry-over impossible flag. It is attached. In other words, in the lottery flag setting process, if a regular bonus is won by internal lottery, the winning state of the regular bonus lottery flag is carried over until the regular bonus is won, and if the big bonus is won by internal lottery, the big bonus lottery A process of carrying over the winning state of the flag until the big bonus is won is performed. At this time, the main board 10 determines whether or not a role other than the regular bonus and the big bonus (small role and replay) is used even in a game in which the winning state of the regular bonus or big bonus lottery flag is carried over by the internal lottery function. An internal lottery is performed. In other words, in the lottery flag setting process, in a game in which the winning state of the regular bonus lottery flag is carried over, if a small role or replay is won in the internal lottery, the regular bonus lottery flag and the internal lottery already won In a game in which the lottery flags corresponding to two or more types of winning combinations or replay lottery flags won in the win state are set to the winning state and the winning state of the big bonus lottery flag is carried over, it is small in the internal lottery When a winning combination or replay is won, a lottery flag corresponding to two or more kinds of winning combinations including a big bonus lottery flag that has already been won and a small bonus or replay lottery flag that has been won in the internal lottery is set to the winning state Set.

  The main board 10 may perform control for changing the winning probability of replay in the internal lottery under a predetermined condition (replay probability changing function). The replay lottery states include a replay no lottery state in which replay is excluded from the internal lottery, a replay low probability state in which the replay winning probability is set to about 1 / 7.3, and a replay winning probability of about 1 / A plurality of lottery states such as a high replay probability state set to 6 can be set. By changing the replay lottery state, the winning probability of the replay in the internal lottery is changed.

  The main board 10 rotates the first reel to the third reel by the stepping motor based on the start signal generated by the player pressing the start switch 134 (rotation start operation) to rotate the first reel to the third reel. In a state where the speed has reached a predetermined speed (about 80 rpm: a rotational speed of about 80 revolutions per minute), control is performed to permit the pressing operation (stopping operation) of the three stop buttons 140 respectively corresponding to the spinning reels. At the same time, control is performed to stop the first reel to the third reel, which are rotationally driven by the stepping motor, in accordance with the lottery flag setting state (internal lottery result) (reel control function).

  When the player presses the three stop buttons 140 in a state where the pressing operation (stop operation) for the three stop buttons 140 is permitted (validated), the main board 10 is based on the reel stop signal. By stopping the supply of drive pulses (motor drive signals) to the stepping motor of the reel unit 203, control is performed to stop each of the first to third reels.

  That is, each time the three stop buttons 140 are pressed, the main board 10 determines the reel stop position corresponding to the pressed button from the first reel to the third reel. Control is performed to stop the reel at the stop position. Specifically, referring to a stop control table (not shown) stored in the storage means (ROM), the first reel according to the pressing timing, pressing order, etc. (stop operation mode) of the three stop buttons. The stop position of the third reel is determined, and the first reel to the third reel are stopped at the determined stop position.

  Here, in the stop control table, the position of the first reel to the third reel (press detection position) at the time when the stop button 140 is operated and the actual stop position (or the slip from the press detection position) of the first reel to the third reel. (Number of frames) is set. Depending on the setting state of the lottery flag, a stop control table for determining the stop positions of the first reel to the third reel may be prepared.

  In the gaming machine, the reel unit 203 includes an index sensor (not shown) including a photo sensor, and the main board 10 is configured to be a reel based on a reference position signal detected by the index sensor every time the reel rotates once. By determining the rotation angle (number of rotation steps of the rotation shaft of the step motor) from the reference position (frame detected by the index sensor), the current rotation state of the reel can be monitored. That is, the main board 10 can obtain the position of the reel when the stop button 140 is operated by determining the rotation angle from the reference position of the reel.

  The main board 10 performs so-called pull-in processing and kick-out processing as control for stopping the reels. The pull-in process is a control process for stopping the reel so that the symbol corresponding to the combination whose lottery flag is set to the winning state is stopped on the winning determination line (so that the winning combination can be won). It is. On the other hand, the kicking process means that the reel corresponding to the combination for which the lottery flag is set to the non-winning state does not stop on the valid winning determination line (so that the non-winning combination cannot be won) This is a control process to be stopped. That is, in the gaming machine of the present embodiment, the lottery flag setting state, the stop button 140 pressing timing, the pressing order, and the stop position of the reels that have already stopped (types of display symbols) in order to realize the pull-in processing and kicking processing. ) Etc., the stop control table is set so that the stop position of each reel changes. In this way, the main board 10 can stop the symbol of the combination for which the lottery flag is set to the winning state in a winning form, while the symbol of the combination for which the lottery flag is set to the non-winning state is in the winning form. Control is performed to stop the first reel to the third reel so as not to stop.

  In the gaming machine of the present embodiment, the first to third reels are set to a control state in which the rotating reel corresponding to the pressed stop button is stopped within 190 ms from the time when the stop button 140 is pressed. ing. That is, in the stop control table for determining the stop position of each rotating reel, the number of frames required from when the stop button 140 is pressed until each reel stops is in the range of 0 to 4 frames (predetermined pull-in range). Is set in

  The main board 10 performs a process of determining whether or not a winning combination has been won based on the stop mode of the first to third reels. Specifically, referring to the winning determination table stored in the storage means (ROM), the symbol combination displayed on the winning determination line when all of the first reel to the third reel are stopped, It is determined whether or not the winning combination is a predetermined combination (winning determination function).

  The main board 10 performs a winning process based on the determination result by the winning determination function. As a process at the time of winning a prize, for example, when a small role wins, the hopper 81 is driven to perform a medal payout control process, or a credit is increased (a predetermined maximum number is increased to 50, for example, When the replay is won, a replay process is performed. When a big bonus or a regular bonus is won, a game state transition control process for shifting the game state is performed.

  The main board 10 performs a payout control process related to the payout of medals according to the game result (payout control function). Specifically, when a small combination wins, the number of medals to be paid out in the game is determined based on a payout predetermined for each combination, and the medals corresponding to the determined number of payouts are determined by the hopper driving unit 80. Then, the hopper 81 is driven to pay out.

  When medal credits (internal storage) are permitted, instead of actually paying out medals by the hopper 81, the number of credits stored in a credit storage area (not shown) of the storage means (RAM) (not shown) A credit addition process for adding the number of payouts to the number of credited medals is performed to virtually pay out medals.

  When the replay wins, the main board 10 performs a replay process (replay process) for setting the same preparation state as the previous game without requiring insertion of medals owned by the player for the next game (replay). Processing function). When a replay wins, an automatic insertion process is performed in which the same number of medals as the previous game is automatically set to the insertion state without using the player's own medals (including credit medals). The game machine is set in a state of waiting for a rotation start operation (pressing operation of the start switch 134 by the player) in the next game in a state where the same winning determination line as the previous game is validated.

  The main board 10 may perform control to shift the gaming state between the normal state, the bonus establishment state, and the bonus state (gaming state transition control function). As the game condition transition condition, one condition may be defined, or a plurality of conditions may be defined. When a plurality of conditions are established, transitioning the gaming state to another gaming state based on the fact that one of the plurality of conditions is satisfied or all of the plurality of conditions are satisfied Can do.

  The normal state is a game state corresponding to the initial state among a plurality of types of game states, and a transition from the normal state to the bonus establishment state is possible. The bonus establishment state is a gaming state that shifts when a big bonus or a regular bonus is won in the internal lottery. In the bonus establishment state, when the big bonus is won in the internal lottery in the normal state, the lottery flag corresponding to the big bonus is maintained in the winning state until the big bonus is won, and the regular bonus is won in the internal lottery in the normal state Until the regular bonus is won, the lottery flag corresponding to the regular bonus is maintained in the winning state. In the bonus state, it is determined whether or not the end condition is satisfied based on the total number of medals paid out by the bonus game, and medals exceeding a predetermined payout limit number are paid out according to the type of bonus won. The bonus state is terminated and the gaming state is returned to the normal state.

  The sub-board 20 is, for example, a BUS composed of a plurality of bits (wirings), a CPU (processing device), a ROM (nonvolatile storage unit), a memory RWM (readable and writable memory), and an I / O (input / output device). ) Are connected. Processing to be described later is executed by the CPU operating according to a program stored in advance in the ROM. When performing processing, the CPU stores various data in the memory RWM, reads as necessary, performs processing, and stores it again as necessary. The memory RWM may have received a battery backup, and in this case, the stored content is retained even during power-off.

Next, game processing in the gaming machine will be described with reference to FIG.
Generally, in a gaming machine, one game is started from the insertion of medals (insertion of credits) until the end of payout (or until the increase in the number of credits is completed). There is a rule that it is not possible to proceed to the next game until one game is finished.

  First, when a prescribed number of medals are inserted, the start switch 134 is activated, and the processing of FIG. 4 is started.

  In step S1, the start switch 134 is turned on by operating the start switch 134. Then, the process proceeds to the next step S2.

  In step S2, an internal lottery is performed by the main board 10. Then, the process proceeds to next Step S3.

  In step S3, the rotation of the first reel to the third reel starts. Then, the process proceeds to the next step S4.

  In step S4, when the stop button 140 is operated, the stop button 140 is turned ON. Then, the process proceeds to the next step S5.

  In step S5, rotation stop processing is performed on the reel corresponding to the pressed stop button 140 among the first to third reels. Then, the process proceeds to the next step S6.

  In step S6, it is determined whether or not the operation of the stop button 140 corresponding to the three reels has been performed. If it is determined that all three stop buttons 140 corresponding to the three reels have been operated, the process proceeds to the next step S7.

  In step S7, it is determined whether or not the winning symbols corresponding to the lottery flag are aligned on the effective winning line while the lottery flag is established, that is, whether or not the winning is confirmed. If it is determined that the winning is confirmed, the process proceeds to the next step S8. If the winning is not confirmed, no medals are paid out even if the lottery flag is established.

  In step S8, medals corresponding to winning symbols are paid out.

  The process from the insertion of the medal to the completion of the execution of step S8 is one game. When the standby process in step S8 ends, the process returns to the beginning of the flowchart. In other words, the next game is possible (transition to the next game).

  Next, the power supply system of the gaming machine according to the embodiment of the invention will be described.

  FIG. 5 is a power system diagram of this gaming machine. In this figure, the same or corresponding parts as in FIG.

A power supply unit 205 supplies current to at least the main substrate 10, the sub substrate 20, and the peripheral substrate connected to the sub substrate 20.
2051 is a rectifier that receives an AC power supply (AC input) connected to the gaming machine and rectifies the AC power supply. Note that the rectifying unit 2051 is not necessary when receiving a DC power supply instead of an AC power supply from the outside. That is, power supply from the outside of the gaming machine may be either AC or DC.

  Reference numeral 2052 denotes an AC-DC converter (first power supply unit) that converts the rectified power supply into a smooth direct current of 24 V (first voltage). The AC-DC converter 2052 includes an overcurrent protection circuit 2052a. This shuts down or reduces the output when a current exceeding the rated value or the upper limit value is output, or when a current exceeding the upper limit value is input from the rectifier unit 2051 (overcurrent detection limiter function). The overcurrent protection circuit 2052a prevents an excessive load from being applied to the AC-DC converter 2052 for a certain period of time and protects the AC-DC converter 2052 from destruction.

  Reference numeral 2053 denotes a DC-DC converter (second power supply unit) that converts the 24V power output from the AC-DC converter 2052 into 12V (second voltage).

  Reference numeral 60 denotes a relay board that is provided between the power supply unit 205 and the sub board 20 and relays a wire harness that connects them.

  Reference numeral 61 denotes a capacitor mounting board connected to a 24V power source output from the AC-DC converter 2052. The capacitor mounting board 61 contains a capacitor (not shown) having a large capacity (for example, 6600 μF).

  The capacitor mounting board 61 supplies, in place of the AC-DC converter 2052, a pulse-like current increase necessary for the sound amplifier 20SA to temporarily generate a loud signal. When stationary sound (or sound that does not change so much even if it is changing sound) is generated, the capacitor of the capacitor mounting board 61 is charged by the current from the AC-DC converter 2052. For example, charging is performed when the sound amplifier 20SA consumes only a current that falls within the rating of the AC-DC converter 2052.

  The reason why the capacitor mounting board 61 is provided between the relay board 60 and the sub board 20 and the reason why it is not provided at the output of the DC-DC converter 2053 will be described later.

  20SA is a sound amplifier (acoustic signal generator) that outputs an acoustic signal for generating sound by driving the speaker (acoustic generator) SP of the speaker substrate 201. The sound amplifier 20SA includes a memory (storage unit) (not shown) and stores acoustic data in advance (acoustic data storage unit). Based on this data, the sound amplifier 20SA generates an acoustic signal.

  The 20MD is a motor driver that generates a drive signal for driving the motors 50M and 50M 'of the movable bodies 50 and 50'.

  The 20LD is an LED driver that generates a light emission signal for blinking the LED.

  20CNV is a DC-DC converter that generates a 5V power supply for the LED driver 20LD.

  W1-1 to W1-3 are first wirings connected to the AC-DC converter 2052 and supplying 24V power to the sound amplifier 20SA. In the example of FIG. 5, the first wiring W1 includes the first wiring W1-1 between the power supply unit 205 and the relay board 60, the first wiring W1-2 between the relay board 60 and the capacitor mounting board 61, and the capacitor mounting board. 61 and a first wiring W1-3 between the sub-board 20.

  W2-1 and W2-2 are second wirings connected to the DC-DC converter 2053 and supplying 12V power to the motor driver 20MD and the LED driver 20LD (specifically, the LED driver 20LD includes a DC-DC). Power is supplied via the converter 20CNV). In the example of FIG. 5, the second wiring W <b> 2 includes a second wiring W <b> 2-1 between the power supply unit 205 and the relay substrate 60, and a second wiring W <b> 2-2 between the relay substrate 60 and the sub substrate 20.

  FIG. 6 shows an example of how the capacitor mounting board 61 is attached.

  In this example, a capacitor mounting board 61 is provided on the case CASE 1 of the sub board 20. According to this embodiment, the length of the first wiring W1-3 can be shortened, and the current of the capacitor of the capacitor mounting board 61 can be supplied quickly and without loss to the sound amplifier 20SA, which is preferable.

  CON1 is an input side connector of the capacitor mounting board 61, CON2 is an output side connector of the capacitor mounting board 61, and CON3 is a connector provided on the sub board 20. One end of the first wiring W1-2 is connected to the connector CON1, and the first wiring W1-3 is connected to the connectors CON2 and CON3. Note that the wirings W1-2 and W1-3 are not shown.

  In the example of FIG. 6, the capacitor mounting board 61 is housed in the case CASE2.

  In the embodiment of the present invention, when the consumption current of the sound amplifier 20SA is sharply changed by the capacitor provided on the capacitor mounting board 61, a part of the current is supplied from the capacitor instead of the AC-DC converter 2052, As a result, the current value output from the power supply unit 205 is lowered. Thereby, even if the rating of the power supply unit 205 is exceeded for a short time, the overcurrent protection circuit 2052a does not operate. A motor or LED can be added without changing the power supply unit 205. The capacitor mounting board 61 is provided in the sound amplifier 20SA because the motor driver 20MD consumes a large current, and the consumption current shows a steady current increase rather than a pulsed current increase (see FIG. 7). This is because it is difficult to compensate for the current. On the other hand, although the load current of the sound amplifier 20SA is relatively large, it rapidly rises and falls rapidly, which is suitable for compensating the peak current with a capacitor.

This will be described in more detail with reference to the timing chart of FIG.
In FIG. 7, in order from the top, a graph of current consumption of the sound amplifier 20SA, a graph of current output from the capacitor corresponding to the peak of current consumption to the sound amplifier 20SA, a motor driver 20MD and a DC-DC converter 20CNV (here 2 is a graph of current (including current supplied to the LED driver 20LD) and an input current of the AC-DC converter 2052 (in this graph, a threshold at which the overcurrent protection circuit 2052a operates is indicated by a dotted line).

  When sound such as stimulating sound effects or up-tempo music is generated, large sound is generated at regular intervals or irregularly, and in response to this, a pulsed power supply current flows into the sound amplifier 20SA. The sign IS of the current consumption of the sound amplifier in FIG. 7 shows how the pulsed power supply current flows. The duration in which the pulsed power supply current flows is denoted by T. Here, “pulsed power supply current” means current consumption that lasts for a short time (about 1 ms) that occurs sharply due to the nature of the sound source. The acoustic data stored in a memory (acoustic data storage unit) (not shown) provided in the sound amplifier 20SA generates sound having a louder volume than a predetermined volume at a predetermined time T or a shorter time. .

  In the example of FIG. 7, the current consumption is approximately Ia at portions other than the symbol IS, but the current consumption increases sharply at the symbol IS. The current consumption other than the peak (reference symbol IS in FIG. 7) (current consumption in a steady state) is Ia. The volume of sound generated when the current value is Ia corresponds to a predetermined volume. If the current value at this time is IS, IS = I′a + Ib. However, I'a> Ia. IS = I′a + Ib is a current value at a peak (reference numeral IS in FIG. 7). The volume of the sound generated when the current value is IS corresponds to a volume larger than a predetermined volume.

  I'a is a value in a range that can be supplied to the sound amplifier 20SA without exceeding the rating by the AC-DC converter 2052 (without operating the overcurrent protection circuit 2052a).

  Ib is a current value that can be supplied by the capacitor mounting board 61 in the duration T of the pulsed power supply current. Ib is at least part of the increment to compensate for the current increasing at time T, ie, the amount I'a alone is insufficient.

  The capacitance of the capacitor provided on the capacitor mounting board 61 is required by the sound amplifier 50SA when the sound amplifier 50SA generates sound (specific sound) with a volume larger than a predetermined volume during a time T or less. The current IS is determined so that a current corresponding to a current (increment) that increases at time T can flow at least for time T, and the overcurrent protection circuit 2052a does not operate at time T. Yes.

  This will be described with reference to FIG.

  When the motors 50M and 50M ′ (all motors) are operating and all the LEDs are lit, the maximum current that can be supplied to the sound amplifier 20SA within a range where the overcurrent protection circuit 2052a does not operate is set. Let Iamax. At time T, Iamax ≧ I′a.

  Since IS = I'a + Ib, Ib> IS-Iamax. The capacitor of the capacitor mounting board 61 has a capacity such that this Ib can be supplied at time T. By increasing the capacity of the capacitor, it is possible to cope with a longer time T and to cope with an increase in current consumption of the sound amplifier 20SA.

  Note that Ia and I'a may be the same, but actually I'a> Ia. The current increases when a sound with a large volume (specific sound) is generated. Initially, the increment (I′a−Ia) is supplied from the AC-DC converter 2052. As the increment increases, the output impedance of the AC-DC converter 2052 increases and the current from there does not increase. As a result, the output impedance of the capacitor becomes relatively low, and the current Ib is supplied from the capacitor instead.

  Thus, by providing the capacitor, the change in the output current from the power supply unit 205 can be moderated. As a result, the peak current value can be lowered. That is, when the load current of the sound amplifier 20SA changes sharply due to the capacitor provided on the capacitor mounting board 61, current is supplied from the capacitor instead of the AC-DC converter 2052, and thereby the current value output from the power supply unit 205 Can be lowered. Even if an upper limit value (overcurrent detection limit) is provided for the current flowing through the AC-DC converter 2052 or its output current, this value will not be exceeded.

  As a result, even if a current exceeding the rating of the power supply unit 205 is required for a short time, the overcurrent protection circuit 2052a does not operate, and thus the motor and LED can be connected without changing the power supply unit 205. Can be added.

  The capacitor mounting board 61 is provided between the relay board 60 and the sub board 20 because the impedance of the wiring W1-3 between the capacitor mounting board 61 and the sound amplifier 20SA is reduced, and a necessary pulsed current is provided. This is because (the increased amount, symbol Ib in FIG. 7) is supplied to the sound amplifier 20SA quickly and with little loss. If the impedance of the wiring W1-3 is large, it may not be able to follow a steep increase in current, and the current of the sound amplifier 20SA may be insufficient. Further, current loss in the wiring W1-3 (loss due to Joule heat) cannot be ignored.

  The reason why the capacitor mounting board 61 is not provided at the output of the DC-DC converter 2053 is that the motor driver 20MD that consumes a larger current for a longer time than the LED shows a steady current increase, not a pulse-shaped current increase. This is because it is difficult to compensate the current with the capacitor (see FIG. 7). On the other hand, although the load current of the sound amplifier 20SA is relatively large, since it rises rapidly and falls rapidly, it is meaningful to provide a capacitor.

  In the embodiment of the present invention, the factor that makes it impossible to use the conventional power supply unit is an increase in current, but among the factors of the increase in current, what can be solved relatively easily is the rapid and short time of the sound (pulse This is based on the knowledge that the current is an increase in current. It is not simply a capacitor provided at the output of the power supply unit.

  FIG. 8 shows a timing chart in a gaming machine (comparative example) that does not include the capacitor mounting board 61. The current I ″ a indicates the peak value of the current supplied from the AC-DC converter 2052 to the sound amplifier 20SA when a loud sound (specific sound) is generated. The current I ″ a has no capacitor. The case where only the AC-DC converter 2052 supplies the current to the sound amplifier 20SA is shown.

  When a large volume is generated, the current increases, but initially, the increment is supplied from the AC-DC converter 2052. As the increment increases, the output impedance of the AC-DC converter 2052 increases, but the sound amplifier 20SA still requires current and more current flows (the sound amplifier 20SA in the code S than the output impedance of the AC-DC converter 2052). This is because the input impedance is low). When the AC-DC converter 2052 supplies the current I ″ a necessary for the code S to the sound amplifier 20SA, the overcurrent detection limit is exceeded (arrow in FIG. 8), the overcurrent protection circuit 2052a is activated, and the output of the power supply unit 205 is Since the overcurrent protection circuit 2052a is actually activated before reaching the peak, the gaming machine stops operating before the current becomes I ″ a.

  Thus, in a gaming machine (comparative example) that does not include the capacitor mounting board 61, the overcurrent protection circuit 2052a is activated due to a rapid and short-time (pulse-like) current increase in sound.

  In the above description, a slot machine has been exemplified as a gaming machine, but the embodiment of the present invention can be applied to other gaming machines such as a pachinko machine.
