Description

  The present invention relates to a gaming machine that generates a big hit state by a lottery process resulting from a gaming operation.

  A ball game machine such as a pachinko machine has a symbol start opening provided on the game board, a symbol display section for displaying a series of symbol variation patterns by a plurality of display symbols, and a big winning opening for opening and closing the opening and closing plate. Configured. When the detection switch provided at the symbol start port detects the passage of the game ball, the winning state is entered, and after the game ball is paid out as a prize ball, the display symbol is changed for a predetermined time in the symbol display section. Thereafter, when the special symbol is stopped in a predetermined manner such as 7-7-7, a big hit state is established, and the big winning opening is repeatedly opened to generate a gaming state advantageous to the player.

  In this type of gaming machine, game members such as tulips and production movable bodies are generally arranged on the game board. These gaming members are driven by an electromagnetic member such as an electromagnetic solenoid or a DC motor that operates at a DC voltage of about 12V to 32V. Also, a launch solenoid that launches a game ball and a ball feed solenoid that guides the game ball to a launch position are generally intermittently energized by receiving a direct current of about 32V.

  A cutting member that realizes an irreversible fusing operation or a reversible interruption operation is disposed in these power supply lines, and the power supply line is automatically cut when the power supply line is short-circuited. . As the cutting member, a fuse that performs a fusing operation is the simplest. Considering the maximum allowable current (4A to 1A) of the power supply line, for example, a cutting member of about 4A fuse to 1A fuse is the power supply line. It is arranged at the most upstream position. If the fuse blows for some reason, it is necessary to identify the cause and replace the circuit board in question with a normal circuit board.

JP 2008-073419 A JP 2004-290308 A JP 2004-181149 A JP-A-10-263184 Japanese Patent Laid-Open No. 10-230040

  As a specific repair work, all the harnesses connecting adjacent circuit boards are first separated from each other for a plurality of circuit boards constituting a series power supply line from the power supply board to the electromagnetic member. Then, by preparing a normal power supply board and restarting power supply in order from the upstream circuit board, the abnormal circuit board is identified.

  If the fuse blows due to a failure (abnormal operation) of the power supply board, there is a possibility that the failed power supply board may destroy the normal circuit board during repair work. Therefore, it is preferable to use a normal power supply board.

  However, after removing all the harnesses, it is necessary to attach the harnesses in order from the upstream circuit board, and this inspection work is very complicated. Moreover, even if a normal power supply board is used to be cautious, overcurrent will flow again when the circuit board in question is connected, so the possibility that the normal power supply board will be destroyed cannot be denied. Is also a big problem. However, it is a measure that is excellent in simplicity, and a configuration that takes such points into consideration is not yet known (Patent Documents 1 to 5).

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine that can identify an abnormal gaming member or circuit board with a simple circuit configuration.

  In order to achieve the above object, the present invention is a gaming machine that performs a lottery process based on a predetermined switch signal and realizes a gaming operation by appropriately operating an electromagnetic member, and receives an AC voltage. A power supply board that generates various DC voltages; and a power supply line that supplies the DC voltage generated by the power supply board to the electromagnetic member. The power supply line includes a plurality of circuit boards connected in series. When the power supply line is in a short-circuited state, an abnormality notifying unit that detects an excessive current and controls the power supply line to be in an open state and continues to flow an alarm current unless the short-circuited state is recovered Is fixedly arranged at a downstream position of the blocking portion or connected when necessary.

  In the present invention, the normal notification unit provided with a normal display body which is turned off when the blocking unit functions and then turned on when the power supply line is restored to the conductive state is fixedly arranged at a downstream position of the blocking unit. Is preferred.

  The electromagnetic member is preferably an electromagnetic solenoid that operates the effect movable body or an electromagnetic motor that operates the effect movable body. In addition, it is effective that the power supply voltage for causing the abnormality notification unit to function is at a lower level than the DC voltage supplied to the electromagnetic member.

  It is effective that the abnormality notifying unit has an abnormality display body that is turned on when the power supply line is short-circuited and then turned off when the short-circuit state is recovered. In addition, it is preferable that the abnormality notification unit is connected to the power supply line through a first energization control element that allows a lighting current of the abnormality display body and blocks a current in the opposite direction.

  The normal notification unit permits a lighting current of the normal display body when the power supply line is at a normal voltage level, while passing through a second energization control element that is not energized at a power supply voltage level that allows the abnormality notification unit to function. It is preferable that the power supply line is connected. Preferably, the abnormality notification unit and / or the normal notification unit should be fixedly connected to the circuit board.

  Further, it is preferable that a rectifier circuit for converting an alternating voltage into a pulsating voltage is provided at an upstream position of the interrupting unit, and an output of the rectifier circuit is directly supplied to the interrupting unit. In this case, it is not only simpler than the case of going through a stabilized power supply circuit etc., but even if the rectifier circuit fails, there is virtually no possibility of excessive current flowing, so if excessive current flows There is an advantage that the cause can be limited to the downstream side of the blocking portion. Examples of the rectifier circuit include a half-wave rectifier circuit and a full-wave rectifier circuit.

  According to the above-described present invention, it is possible to identify an abnormal gaming member or circuit board while having a simple circuit configuration.

It is a perspective view of the pachinko machine shown in an example. It is the front view which illustrated the game board of the pachinko machine of FIG. It is a block diagram which shows the whole structure of the pachinko machine of FIG. It is a block diagram showing a circuit configuration of an effect control unit. It is a block diagram which shows an electric power feeding line. It is a circuit diagram which shows a short circuit alert circuit concretely.

  Hereinafter, the present invention will be described in detail based on examples. FIG. 1 is a perspective view showing a pachinko machine GM of the present embodiment. This pachinko machine GM includes a rectangular frame-shaped wooden outer frame 1 that is detachably mounted on an island structure, and a front frame 3 that is pivotably mounted via a hinge 2 fixed to the outer frame 1. It is configured. A game board 5 is detachably attached to the front frame 3 from the front side, not from the back side, and a glass door 6 and a front plate 7 are pivotally attached to the front side so as to be openable and closable.

  On the outer periphery of the glass door 6, an electric lamp such as an LED lamp is arranged in a substantially C shape. On the other hand, a speaker is disposed below the glass door 6.

  The front plate 7 is provided with an upper plate 8 for storing game balls for launching, and a lower plate 9 for storing game balls overflowing or extracted from the upper plate 8 and a launch handle at the lower part of the front frame 3. 10 are provided. The launch handle 10 is interlocked with the launch motor, and a game ball is launched by a striking rod that operates according to the rotation angle of the launch handle 10.

  A chance button 11 is provided on the outer peripheral surface of the upper plate 8. The chance button 11 is provided at a position where it can be operated with the left hand of the player, and the player can operate the chance button 11 without releasing the right hand from the firing handle 10. The chance button 11 does not function normally, but when the gaming state becomes the button chance state, the built-in lamp is turned on and can be operated. The button chance state is a gaming state provided as necessary.

  On the right side of the upper plate 8, an operation panel 12 for ball lending operation with respect to the card-type ball lending machine is provided, a frequency display unit for displaying the remaining amount of the card with a three-digit number, and a ball of game balls for a predetermined amount A ball lending switch for instructing lending and a return switch for instructing to return the card at the end of the game are provided.

  As shown in FIG. 2, a guide rail 13 made of a metal outer rail and an inner rail is provided in an annular shape on the surface of the game board 5, and a central opening HO extending toward the back side is provided in the approximate center. It has been. A display device DISP composed of a liquid crystal color display is arranged at the bottom of the central opening HO. In addition, a symbol starting port 15, a big winning port 16, a normal winning port 17, and a gate 18 are arranged at appropriate positions in the game area.

  Each of these winning openings 15 to 18 has a detection switch inside, and can detect the passage of a game ball. When it is detected that a game ball has won at the symbol start opening 15, a big hit lottery process is executed and the game state is shifted to a game state advantageous to the player as long as the holding upper limit value (four in the embodiment) is not exceeded. Whether or not to do so is determined by lottery.

  In a space formed on the front surface of the display device DISP, a movable effect body AMU that executes a movable effect is disposed so as to be movable up and down. The movable effector AMU is configured to be held by the left and right lifting mechanisms ALVa and ALVb, and moves up and down at high speed along the guide shaft PL in accordance with the rotation of the lifting motors MOa and MOb that drive the lifting mechanisms ALVa and ALVb.

  The movable effect body AMU moves to a target position at the bottom of the display device DISP and executes an appropriate movable effect during the movable effect. This movable effect is realized by moving the movable member forward and backward by temporarily energizing the game solenoid SL5.

  The display device DISP is a device that variably displays a specific symbol related to the big hit state and displays a background image and various characters in an animated manner. This display device DISP has a special symbol display part Da to Dc in the center, a normal symbol display part 19 in the upper right part, and a reserved number display part NUM in the lower center part.

  In the special symbol display portions Da to Dc, a reach effect is executed to expect that a big hit state will be brought about by the big win lottery, and the special symbol display portions Da to Dc and the surroundings indefinitely notify the success / failure result of the big win lottery. A notice effect is performed. The normal symbol display unit 19 displays a normal symbol. When a game ball that has passed through the gate 18 is detected, the normal symbol fluctuates for a predetermined time and is extracted at the time when the game ball passes through the gate 18. The stop symbol determined by the random number for lottery is displayed and stopped.

  For example, the symbol start opening 15 is configured to be opened and closed by an electric tulip having a pair of left and right opening and closing claws. When the stop symbol after the fluctuation of the normal symbol display unit 19 hits and the symbol is displayed, the opening and closing claw is predetermined. It is released only for a time or until a predetermined number of game balls are detected. The electric tulip is opened and closed by intermittent energization of the start port solenoid SL3.

  When a game ball wins the symbol start opening 15, an image effect in which the display symbols of the special symbol display portions Da to Dc change for a predetermined time is started on the condition that the timing is not being executed. The game stops at a stop symbol determined based on the jackpot lottery result corresponding to the winning timing of the game ball to 15. On the other hand, if a game ball wins at the symbol start opening 15 during the image production, the big hit lottery process is put on hold unless the hold upper limit value (4 pieces) is reached, and the increased production hold number is displayed on the hold number display portion NUM. Is done. When the game ball is won at the symbol start opening 15 exceeding the holding upper limit value, the game ball is simply paid out as the winning ball operation, and the big hit lottery process is not executed.

  In the special symbol display portions Da to Dc and the surroundings, a notice effect may be executed during a series of image effects. In addition, as a kind of notice effect, the movable effector AMU may descend to the position of the central opening HO. And the movable production | presentation body AMU which fell to the target position raises to the original origin position, after performing a suitable movable production | presentation.

  The big prize opening 16 is controlled to open and close by, for example, an opening / closing plate 16a that can be opened forward, but when the stop symbol after the symbol change of the special symbol display portions Da to Dc is a big hit symbol such as “777”, “big hit game” Is started, and the opening / closing plate 16a is opened. The opening / closing plate 16a is opened by energizing the opening / closing solenoid SL4.

  After the opening / closing plate 16a of the big prize opening 16 is opened, the opening / closing plate 16a is closed when a predetermined time elapses or when a predetermined number (for example, 10) of game balls wins. In such an operation, the special game is continued up to 15 times, for example, and is controlled in a state advantageous to the player. In addition, when the stop symbol after the change of the special symbol display parts Da to Dc is a specific symbol of the special symbols, a privilege that the game after the end of the special game is in a high probability state is given.

  FIG. 3 is a block diagram showing an overall circuit configuration of the pachinko machine GM of the present embodiment. A one-dot broken line arrow in the figure mainly indicates a DC voltage line.

Further, the control command CMD ′ output from the effect control board 22 is transmitted to the image control board 23 via the effect interface board 27, and the control command CMD ″ output from the main control board 21 is the main board relay board. 28 is transmitted to the payout control board 24. The effect interface board 27 and the effect control board 22 are directly connected by a connector without using a cable.

  The main control board 21, the effect control board 22, the image control board 23, and the payout control board 24 are each equipped with a computer circuit including a one-chip microcomputer. Thus, the circuits mounted on the control boards 21 to 24 and the operations realized by the circuits are collectively referred to as a function. In this specification, the main control unit 21, the effect control unit 22, and the image control unit 23 are used. , And the payout control unit 24. All or part of the effect control unit 22, the image control unit 23, and the payout control unit 24 is a sub-control unit.

  By the way, the pachinko machine GM is roughly divided into a frame side member GM1 surrounded by a broken line in FIG. 3 and a board side member GM2 fixed to the back of the game board 5. The frame side member GM1 includes a front frame 3 on which a glass door 6 and a front plate 7 are pivotally attached, and a wooden outer frame 1 on the outside thereof. Is fixedly installed. On the other hand, the board side member GM2 is replaced in response to the model change, and a new board side member GM2 is attached to the frame side member GM1 instead of the original board side member. All except the frame side member GM1 is the panel side member GM2.

  3, the frame side member GM1 includes a power supply board 20, a payout control board 24, a launch control board 25, a frame relay board 32, an external terminal board OT, and a ball lending machine UT. Interface board IF, and these circuit boards are respectively fixed at appropriate positions of the front frame 3. On the other hand, on the back of the game board 5, a main control board 21, an effect control board 22, and an image control board 23 are fixed together with the display device DISP and other circuit boards. And the frame side member GM1 and the board | substrate side member GM2 are electrically connected by the connection connectors CN1-CN4 concentratedly arranged in one place.

  As shown in FIG. 3, the power supply board 20 is connected to the main board relay board 28 through the connection connector CN2, and is connected to the power supply relay board 30 through the connection connector CN3. The main board relay board 28 outputs the system reset signal SYS, the RAM clear signal, the voltage drop signal, the backup power supply, DC12V, and DC32V received from the power board 20 to the main controller 21 as they are. Similarly, the power relay board 30 also outputs the system reset signal SYS received from the power board 20 and the AC and DC power supply voltages to the effect interface board 27 as they are. The production interface board 27 outputs the received system reset signal SYS to the production control unit 22 and the image control unit 23 as they are.

  On the other hand, the payout control board 24 is directly connected to the power supply board 20 without going through the relay board, and receives the same system reset signal SYS, RAM clear signal, voltage drop signal, backup power supply as the main control unit 21 receives. Directly with other power supply voltages.

  Here, the system reset signal SYS output from the power supply board 20 is a signal indicating that the AC power supply 24V is supplied to the power supply board 20, and the one-chip microcomputer or other IC element of each of the control units 21 to 24 by this signal. The power is reset. The RAM clear signal received from the power supply board 20 by the main control unit 21 and the payout control unit 24 is a signal that determines whether or not to initialize all areas of the built-in RAM of the one-chip microcomputer of each control unit 21 and 24. Thus, it has a value corresponding to the ON / OFF state of the initialization switch operated by the staff.

  The voltage drop signal received from the power supply board 20 by the main control unit 21 and the payout control unit 24 is a signal indicating that the AC power supply 24V has started to drop. By receiving this voltage drop signal, each control unit 21, In 24, a necessary termination process is started prior to a power failure or business termination. The backup power source is a DC 5V DC power source that retains data in the built-in RAM of the one-chip microcomputer of the main control unit 21 and the payout control unit 24 even after the AC power source 24V is shut off due to business termination or power failure. Therefore, the main control unit 21 and the payout control unit 24 can resume the game operation before power-off after power-on (power backup function). This pachinko machine is designed to retain the stored contents of the RAM of each one-chip microcomputer for at least several days.

  On the other hand, the effect control unit 22 and the image control unit 23 are not provided with the power supply backup function described above. However, the system reset signal SYS is commonly supplied to the effect control unit 22 and the image control unit 23, and the power reset operation is realized at a timing substantially synchronized with the other control units 21 and 24.

  As shown in FIG. 3, the main control unit 21 receives switch signals such as the symbol start port 15, the big winning port 16, the normal winning port 17, and the gate 18 via the game board relay board 29. Further, the main control unit 21 outputs a solenoid signal for opening and closing a game member such as an electric tulip via the game board relay board 29.

  As shown in FIGS. 3 and 4, the effect interface board 27 includes a command relay board 26, a power supply relay board 30, a frame relay board 31, an effect control board 22, a lamp connection board 34, and an effect relay board 35. Are connected to the image control board 23 and the inverter board 33.

  As shown in FIG. 4, the effect control unit 22 stores a one-chip microcomputer 40 that executes processing such as a sound effect, a lamp effect, a notice effect by a movable effector, and data transfer, and a control program for the one-chip microcomputer 40. EPROM 41 to be played, an audio reproduction output circuit 42 for reproducing and outputting an audio signal based on an instruction from the one-chip microcomputer 40, and an audio memory 43 for storing compressed audio data which is original data of the audio signal to be reproduced And a watchdog timer WDT.

  The one-chip microcomputer 40 includes a parallel input / output port PIO. The parallel port PIO outputs drive data for rotating the elevating motors MOa and MOb constituting the movable effect body AMU, together with the control command CMD 'and the strobe signal STB'. The output drive data is supplied to each of the motors MOa to MOb via the production relay board 35. Each of the motors MOa to MOb is a stepping motor.

  The watchdog timer WDT is reset by a clear pulse periodically supplied from the one-chip microcomputer 40. When the clear pulse is interrupted due to a program runaway or the like, a reset signal RESET is output. As a result, the one-chip microcomputer 40 is forcibly reset to the initial state, and the program runaway state is solved.

  As shown in FIG. 4, the control command CMD and the strobe signal (interrupt signal) STB output from the main control board 21 are sent to the one-chip microcomputer 40 of the effect control board 22 via the buffer 48 of the effect interface board 27. Is supplied. The interrupt signal STB is supplied to the interrupt terminal INT of the one-chip microcomputer. And the presentation control part 22 acquires the control command CMD by the reception interruption process started by the strobe signal STB.

  In addition to (a) error notification and other notification control commands, the control command CMD acquired by the effect control unit 22 includes (b) control for specifying an outline of various effect operations resulting from winning at the symbol start opening. Commands (variation pattern commands) are included. Here, the outline of the production operation specified by the variation pattern command includes the production total time from the production start to the production end, and the result of winning or failing in the big hit lottery. In addition to these, the change pattern command including the presence or absence of the reach effect or the notice effect may be specified, but even in this case, the specific content of the effect content is not specified.

  Therefore, when the effect control unit 22 acquires the variation pattern command CMD, the effect lottery is subsequently performed, and the effect outline specified by the acquired variation pattern command is further specified.

  For example, the specific contents of the reach effect and the notice effect are determined. Then, in accordance with the determined specific game content, a lamp effect by blinking the LED group and a sound effect preparation operation by the speaker are performed, and the image control unit 23 is synchronized with the effect operation by the lamp and the speaker. The control command CMD ′ relating to the performed image effect is output. Further, during the advance notice operation using the movable effect body AMU, after the elevating motors MOa and MOb are rotated, the game solenoid SL5 is energized to execute an appropriate movable effect.

  In order to realize an image effect synchronized with various effect operations including such a movable effect, the effect control unit 22 sends a control command CMD ′ to the effect interface together with a strobe signal (interrupt signal) STB ′ for the image control unit 23. Output toward the substrate 27. When the notification control command related to the display device or other control commands is received, the effect control unit 22 outputs the control command to the effect interface board 27 together with the interrupt signal STB ′. .

  Corresponding to the configuration of the effect control board 22, the effect interface board 27 is configured to receive an 8-bit control command CMD 'and a 1-bit interrupt signal STB'. These data CMD ′ and STB ′ are output to the image control board 23 via the buffer circuit 46 as they are. The effect interface board 27 receives a lamp driving signal output from the effect control unit 22 and supplies the signal to the LED lamp group via the lamp connection board 34. As a result, a lamp effect corresponding to the control command CMD output from the main control unit 21 is realized.

  FIG. 5 illustrates a DC 32 V distribution path among various DC voltages (5 V, 12 V, 15 V, and 32 V) generated by the power supply substrate 20. Note that DC32V is generated as output voltages of two rectifier circuits REC that full-wave rectify AC24V, and is output to each circuit board via fuses Fu (FIG. 6) arranged in the short-circuit notification circuits 60a and 60b. Has been.

  In this embodiment, a launch solenoid SL1 for launching a game ball, a ball feed solenoid SL2 for moving the game ball to a predetermined position, a start port solenoid SL3 for opening / closing the symbol start port 15, and an open / close solenoid SL4 for opening / closing the opening / closing plate 16a. All of the game solenoids SL5 for advancing and retracting the game members are configured to intermittently operate at DC 32V.

  As shown in the figure, the DC 32V output via the short-circuit notification circuit 60a is supplied to the firing solenoid SL1 and the ball feed solenoid SL2 via the dispensing control board 24 and the firing control board 25. The DC 32V output via the short-circuit notification circuit 60b is supplied to the start-up solenoid SL3 and the opening / closing solenoid SL4 via the main control board 21 and the gaming machine relay board 29. When evaluated with these DC 32V power supply lines, the payout control board 24 and the launch control board 25 are in a serially connected relationship, and the main control board 21 and the gaming machine relay board 29 are also in a serially connected relationship.

  Also, the DC 32V output from the short-circuit notification circuit 60b branches at the effect interface board 27, one of which is supplied to the game solenoid SL5 via the effect relay board 34, and the other is supplied to the inverter board 33. Yes. A game solenoid SL5 and elevator motors MOa and MOb are connected to the effect relay board 34, DC 32V is supplied to the game solenoid SL5, and DC 12V that is stepped down by the effect interface board is supplied to the elevator motors MOa and MOb. Is supplied. The DC 32V supplied to the inverter board 33 is converted into an AC high voltage to drive the backlight unit BL of the LCD unit.

  As described above, in this embodiment, there are three systems of power supply lines (DC32V) configured by connecting a plurality of circuit boards in series. Each power supply line is only connected to an input terminal of a DC / DC converter or an inverter IN except for being supplied to an electromagnetic component such as an electromagnetic solenoid or a smoothing capacitor. Is not connected.

  In addition, short-circuit notification circuits 60a and 60b shown in FIG. 6 are arranged on the power supply board 20 at the most upstream position of each power supply line. The two short-circuit notification circuits 60 (60a, 60b) have the same basic configuration, but correspond to the maximum allowable current, either a 4A fuse Fu that blows with an overcurrent of 4A, or an overcurrent of 3A. A 3A fuse Fu to be blown is disposed at a downstream position of the full-wave rectifier circuit REC.

  FIG. 6 illustrates a circuit configuration of the short-circuit notification circuit 60. The short-circuit notification circuit 60 is divided into an abnormal lighting unit 61 that lights the abnormal lamp D1 when the power supply line LN is overcurrent, and a normal lighting unit 62 that lights the normal lamp D2 when the power supply line LN is normal. Has been.

  The abnormal lighting unit 61 is a lamp driving circuit that sets the power supply voltage Vcc to 5 V, and includes an abnormal lamp D1, an N-type transistor (FET: TR), and a bias resistor R1, which determines the gate voltage of the N-type transistor. R2 includes a current limiting resistor R3, and a diode D3 that is energized when the fuse Fu is blown.

  On the other hand, the normal lighting unit 62 includes a normal lamp D2, a Zener diode ZD that breaks down upon receiving a voltage exceeding DC5V, and a current limiting resistor R4.

  As shown in the figure, the output of the full-wave rectifier circuit REC is supplied to the power supply line LN of each circuit board via the fuse Fu for 3A or 4A, and is normally DC 32V. Therefore, if the power supply line LN is in a normal state (32 V), the diode D3 is cut off, no current flows through the abnormal lighting unit 61, and the abnormal lamp D1 is turned off. On the other hand, since the power supply line LN is 32V, the Zener diode ZD breaks down, current flows from the current limiting resistor R4 → the Zener diode ZD → the normal lamp D2, and the normal lamp D2 is turned on.

  As described above, in this embodiment, the normal lamp D2 is kept on and the abnormal lamp D1 is kept off when normal. However, if an overcurrent flows through the power supply line LN for some reason, the fuse Fu is melted correspondingly, and the power supply line LN is cut off. The impedance when the power supply line LN is interrupted is 32/3 [Ω] or 32/4 [Ω] or less corresponding to the fusing current (3A, 4A) of the fuse Fu.

  As described above, when the impedance of the power supply line LN drops to about 10Ω or less, the diode D3 is energized and the abnormal lighting unit 61 becomes operable. In this case, a bias voltage of 5 * R2 / (R1 + R2) is applied between the gate terminal and the source terminal of the transistor TR. In this embodiment, this bias voltage (= 5 * R2 / (R1 + R2)) is applied. Since it is set to be about 2V, the transistor TR is turned on, the ON current flows through the path of the power supply voltage 5V → current limiting resistor R3 → abnormal lamp D1 → transistor TR → diode D3, and the abnormal lamp D1 is lit. It becomes. Since the breakdown voltage of the Zener diode ZD is higher than 5V, the normal lamp D2 is not lit.

  As described above, in this embodiment, when the power supply line LN is shut off due to overcurrent, the normal lamp D2 is turned off, while the abnormal lamp D1 is turned on, so that the abnormal state is reliably notified. Therefore, such a broken gaming machine is returned to the manufacturer, or maintenance personnel are dispatched to the gaming hall for repair.

  In the case of the conventional gaming machine, it is necessary to remove the harness (a bundle of many wirings) for connecting the circuit boards in series at the time of repair work. In the case of this embodiment, such a complicated No preparatory work is required. That is, in the repair work of the present embodiment, the electromagnetic components and the circuit board may be removed in order from the most downstream position of the power supply line LN. When any member is removed and the abnormal lamp D1 is extinguished, it can be specified that the member removed at the time of extinction is abnormal.

  In addition, since the possibility that a plurality of members are out of order is not zero, after replacing a member that has specified an abnormality, the abnormal lamp D1 is lit again while attaching the original member downstream from it. It is preferable to confirm that it does not. If the abnormal lamp does not light even when the most downstream member is mounted, the short circuit state of the power supply line LN has been eliminated.

  By the way, since there is only a simple full-wave rectifier circuit REC on the upstream side of the short-circuit notification circuit 60 of this embodiment, the possibility that an overcurrent flows due to the failure of the circuit is extremely low. The above-described repair work can be performed without preparing the device, which is also preferable in this respect.

  As mentioned above, although the Example of this invention was described in detail, the concrete description content does not specifically limit this invention. For example, in the embodiment, the short-circuit notification circuit 60 is arranged on the power supply board, but is not particularly limited as long as it is the most upstream position of the power supply line LN. Further, the arrangement of the short-circuit notification circuit 60 is not necessarily limited to the 32V power supply line. Instead of this, or in addition to this, the power supply line exceeding the power supply voltage of the abnormal lighting unit 61 such as 12V or 15V is used. It may be arranged.

  In the above embodiment, the short-circuit notification circuit 60 including the abnormal lighting unit 61 and the normal lighting unit 62 is fixed to the circuit board. That is, while the normal lighting unit 62 is fixed to the circuit board, the maintenance lighting member may hold the abnormal lighting unit 61 as a single inspection member. However, in this case, it is necessary to connect the inspection member (61) to the power supply voltage 5V and the power supply line prior to the repair work, which is not preferable because the work is complicated. That is, the configuration of the embodiment is more preferable.
