  In FIG. 6, a battery 51 is a battery as a constant voltage source having a rating of 5 V, for example, and constantly supplies power to the abnormality detection unit 52. The battery 51 may be a battery that can be charged from the power supply device substrate 330 described above as needed.

  The notification means 53 connected as the output means of the abnormality detection unit 52 includes a plurality of light emitting diodes LED1. The light-emitting diode LED1 is provided, for example, on the front panel of the slot machine 1 and emits light to notify the periphery of the slot machine 1 of an abnormality. Further, the light emitting diode LED1 of the notification means 53 is built in the above-described effect lamps 211, 226a, 226b, and the anomaly of the slot machine 1 detected by the anomaly detection unit 52 is indicated in the effect lamps 211, 226a, 226b may notify.

  Although not shown, the notification unit 53 may further include an amplifier and a speaker, and may generate a warning sound around the slot machine 1 as the light emitting diode LED1 is turned on. In this case, the above-mentioned speakers 252a, 252b, 253a, 253b provided on the front door 2 for use in the production of the slot machine 1 may be substituted for the speakers of the notification means 53.

  Further, the notification means 53 is a monitor system installed in a manager room of a hall (game room), and may be connected to the slot machine 1 via a wiring cable and remotely operated. The notification means 53 is a communication control board that can be connected to a network system including a hall computer installed in a hall administrator room, and notifies the hall computer of an abnormality of the slot machine 1 via the network system. It may be a thing.

  The abnormality detection unit 52 includes a transistor Q1 that constantly supplies current from the battery 51 to the light emitting element 275a of the door sensor 275, and a transistor Q2 that outputs an abnormality detection signal by supplying current to the notification means 53 when an abnormality is detected. And. The light receiving element 275b of the door sensor 275 is connected to the base of the transistor Q2. When the door sensor 275 is on (when the front door 2 is closed by the housing 3), the potential of the base of the transistor Q2 is set. By dropping to the ground level, the transistor Q2 is turned off. On the other hand, when the front door 2 is opened and the door sensor 275 is turned off, a predetermined amount of current is supplied from the battery 51 to the base of the transistor Q2 via the resistor element R3. The transistor Q2 is turned on to drive the notification means 53.

  Here, the abnormality detection unit 52 has a circuit configuration in which an abnormality is determined when the door sensor 275 is turned off, and an abnormality detection signal is output to the notification unit 53 at the subsequent stage. According to this, even when the connection to the door sensor 275 is broken or the door sensor 275 stops functioning, such as when the connector of the door sensor 275 is disconnected or the wiring is cut, the abnormality detection unit 52 also detects the abnormality detection signal. Is output, which increases safety.

  Further, the abnormality detection unit 52 is connected to the power supply device substrate 330 described above, and an on / off signal indicating that the main power supply of the slot machine 1 is on or off is supplied via the connection terminal M1. Good. In this case, the abnormality detection unit 52 and the battery 51 are connected via, for example, the B contact relay SW1, and the on / off signal from the power supply board 330 is supplied to the control input terminal of the relay SW1. Then, when the main power supply of the slot machine 1 is on, the relay SW1 can be cut off so that the abnormality detection device is not operated.

  Since this abnormality detection device is driven by the battery 51 described above, it always operates in an infinite loop as shown in the flowchart of FIG. In step S <b> 101, the abnormality detection device always determines whether the front door 2 has been opened by the abnormality detection unit 52 constantly monitoring the detection signal of the door sensor 275. Here, at the normal time, the front door 2 is closed to the housing 3 side, and the door sensor 275 is turned on.

  In step S101, for example, when the front door 2 is opened by a person who has illegally entered the hall and the door sensor 275 is turned off, the transistor Q2 of the abnormality detection unit 52 is turned on, and current is supplied to the notification means 53. In step S102, the notification means 53 receives this and causes the light emitting diode LED1 to emit light or sound a speaker or the like, thereby notifying the periphery of the slot machine 1 or an administrator or the like.

  According to the slot machine 1 including the abnormality detection device having such a configuration, the abnormality detection unit 52 driven by the battery 51 constantly monitors the open / closed state of the front door 2, so that the main power of the slot machine 1 is cut off. Even if it exists, it can alert | report to an administrator etc. that the front door 2 was opened. Accordingly, it is possible to always prevent an illegal action such as replacement of an electronic component provided in the housing 3 of the slot machine 1 by a person who has entered the hall, and the safety in the slot machine 1 is improved.

  In this abnormality detection device, when an abnormal state in which the front door 2 is opened is detected, a holding circuit for temporarily storing and holding the abnormality detection signal output via the connection terminal M2 shown in FIG. It can also be provided. This holding circuit is driven by a battery 51 as in the case of the abnormality detection unit 52, and is configured by a known circuit such as a flip-flop circuit or a self-holding circuit using a relay. It is preferable that the holding circuit further outputs the stored and held information to the main control board 100.

  In this case, for example, even if the front door 2 is illegally opened at night when the main power of the slot machine 1 is turned off and the internal control board or the like is altered illegally, the front door 2 The holding circuit stores and holds the history that the memory has been opened, and before the main power of the slot machine 1 is turned on and the game is executed, the main control board 100 checks the holding information of the holding circuit and finds that there is an abnormality. When the history to be shown is obtained, the main control board 100 performs processing for stopping execution of the game. As a result, the fraudster cannot illegally play a game with a high payout, for example, using the slot machine 1 that has been illegally modified, and the damage on the hall side is suppressed.
