In the invention according to claim 4, by folding the front frame abutting portion, the employee can avoid accidentally colliding the front door opened in the inspection work with the front frame abutting portion, and the gaming machine is damaged. Can be prevented.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a diagram for explaining a schematic configuration of an anti-fraud device for a gaming machine according to the present invention. The reel winding device 1 is screwed to the island frame 3 of the gaming machine island. From this reel winding device 1, a rope 4 such as a chain, a wire, or a wire rope is drawn out.

  In FIG. 1, the locking member 2 has a plate-like main portion 21, and the front end of the locking member 2 is bent inwardly at a right angle to form a front frame contact portion 22. The locking member 2 may be a square bar or the like, and is not particularly limited in material and shape, but is preferably a material that is not easily deformed or broken. As shown in FIGS. 2 and 3, the locking member 2 is disposed so as to be slidable in the front-rear direction through the inter-stand column (column between gaming machines) 31 on the side where the front frame 5 is opened. . The rear end of the locking member 2 is connected to the rope 4 of the reel winding device 1. The cord 4 is extended and stretched in the same direction as the plate-like main portion 21 at the rear end of the locking member 2, but the direction is changed by the pulley 32 and is wound around the reel winding device 1. In FIG. 2, 7 is a gaming machine main body.

  The front frame abutting portion 22 is in contact with the front frame 5 so as to close the key hole for locking the front frame, but the height of the position of the key hole varies depending on the manufacturer and model. Therefore, for example, as shown in FIG. 3, if the insertion hole 33 of the locking member 2 provided in the inter-post column 31 is long in the vertical direction, the vertical direction of the front frame abutting portion 22 corresponds to the position of the key hole. Adjust the position to close the keyhole entrance. In this way, by bringing the front frame contact portion 22 into contact with the key hole, the double lock that prevents the key from being inserted into the key hole and the locking member 2 prevents the front frame 5 from being opened is provided. Can be applied. When the front frame contact portion 22 is made of metal, the front frame 5 may be wrinkled. Therefore, it is desirable to arrange a cushion body 23 such as a sponge or a rubber plate to prevent this. .

  4 and 5 show the internal structure of the reel winding device 1. The reel take-up device 1 includes a take-up reel 12 decorated with a support shaft 11 and a claw wheel 13. One end of the rope 4 is fixed to the take-up reel 12 and wound. The take-up reel 12 is urged in the direction in which the rope 4 is scraped off by a spring 15.

  An electric lock mechanism 6 includes a claw member 61 and a solenoid 62. The claw member 61 rotates in the vertical direction around the support shaft 63. When the solenoid 62 is energized, the plunger 64 is retracted, the rear end of the claw member 61 is lowered by its own weight, and the tip is raised. Yes. As a result, the tip of the claw member 61 enters the recess 14 on the outer periphery of the claw wheel 13 as shown in FIG. 4, and restricts clockwise rotation in the figure. In this state, the take-up reel 12 can rotate in the counterclockwise direction for picking up the wire 4, but cannot rotate in the clockwise direction for pulling out the wire 4 due to the locking action of the claw member 61.

  In the unauthorized opening prevention device configured as described above, when it is necessary to open the front frame 5 during business hours, if the energization of the solenoid 62 is stopped and the plunger 64 is protruded, the claw member 61 The rear end is pushed up, the front end is lowered, and is removed from the recess 14. Accordingly, the take-up reel 12 can be rotated clockwise to pull out the rope 4, so that the rope 4 can be loosened and the front frame 5 can be opened.

  On the other hand, when the solenoid 62 is operated and the plunger 64 is moved backward, the tip of the claw member 61 bites into the concave portion 14 to prevent the take-up reel 12 from rotating backward. The stop member 2 cannot be pulled out. In this state, the front frame 5 can be kept unopenable by winding the wire with the take-up reel 12 and bringing the front frame contact portion 22 of the locking member 2 into contact with the front frame 5. Therefore, even if a suspicious person attempts to cheat by opening the front frame 5 outside business hours, the cheating cannot be done.

  In addition, since the locking member 2 shown in FIG. 5 made it possible to bend the front frame contact portion 22 backward by 90 ° by the hinge, when trying to close the front frame 5 when the inspection was completed, Even if an operator accidentally collides the front surface with the front frame abutting portion 22, the collision can be avoided by the folding, so that an expensive gaming machine is not damaged.

  Since the unauthorized opening prevention device of the present invention can be installed separately from the gaming machine on the island stand or the inter-stand pillar, the replacement of the new stand is easy. In addition, since there is no remodeling of the gaming machine, there is an advantage that it does not take time to submit a certificate change notification and obtain permission.
