The metal fittings 23 and 24 on the inner side of the frame 20 come into contact with each other, whereby the front frame lock claws 2 and 3 are rotated upward. At this time, the sliding lock members 4 and 5 are biased downward by the biasing force of the spring members 14b and 14e. When the locking grooves 2c and 3c of the table frame lock claws 2 and 3 reach the positions of the locking portions 4a and 5a of the sliding lock members 4 and 5, as shown in FIG. 5a fits into the locking grooves 2c and 3c, and the receiving brackets 23 and 24 are locked and held inside the front frame lock claws 2 and 3, and the front frame 21 is locked.

  Thus, in the locked state of the front frame 21, the locking portions 4 a and 5 a of the sliding lock members 4 and 5 are fitted into the locking grooves 2 c and 3 c of the front frame locking claws 2 and 3, so that the front frame locking claw 2 is inserted. , 3 are locked. For this reason, even if an illegal instrument such as a wire is inserted through the gap between the front frame 21 and the main body frame 20 of the gaming machine and hooked at the tip, the front frame locking claws 2 and 3 are moved to the unlocking side. Since the lock claws 2 and 3 are locked by the locking portions 4a and 5a of the sliding lock members 4 and 5, tilting to unlocking is impossible.

  Therefore, the front frame lock claws 2 and 3 in the locked state cannot be tilted in the unlocking direction, and the front frame lock claws 2 and 3 cannot be moved by inserting a wire or the like through the gaps in the front frame. Correct unlocking can be prevented. In the locked state, the first and second engaging projections 10a and 10b of the cam member 10 are held in the engagement holes 8f and 8g of the operating band plate 8, and the movement of the operating band plate 8 is maintained. Is locked.

  In other words, in the cylinder lock 9 with the key removed, the lock shaft 9b cannot rotate and cannot rotate, so the cam member 10 is locked by the cylinder lock 9, and the operating band plate 8 is fixed to the cam member 10. Is prevented from sliding up and down. For this reason, even if it is attempted to slide the front frame locking claws 2 and 3 by hooking the tip of an unauthorized device and moving the operating frame plate 8, the operating band plate 8 does not slide, and unauthorized unlocking can be prevented. .

  On the other hand, when the glass frame 22 is closed with respect to the front frame 21, the tip inclined portions of the pair of glass frame locking claws 6, 7 hit the receiving brackets 25, 26 of the glass frame 22, and once slide downward. By returning upward by the urging force of the members 14 a and 14 d, the glass frame lock claws 6 and 7 are locked to the metal fittings 25 and 26 of the glass frame 22.

  When the front frame 21 is unlocked, when the key is inserted into the cylinder lock 9 and turned to the right, the first engagement convex portion 10a of the cam member 10 rotates counterclockwise in FIG. The operating band plate 8 is moved upward by engaging with the engaging hole 8g. At this time, as shown in FIG. 10, the engaging portions 8d and 8e of the operating band plate 8 are engaged with the engaging portions 4a and 5a of the sliding lock members 4 and 5, and the sliding lock members 4 and 5 are spring-loaded. The members 14b and 14e are slid upward against the urging force of the members 14b and 14e, and the locking portions 4a and 5a are removed from the locking grooves 2c and 3c of the front frame lock claws 2 and 3, respectively.

  As a result, the front frame locking claws 2 and 3 are unlocked by the locking portions 4a and 5a, tilted downward by the urging force of the spring members 14b and 14e, disengaged from the receiving brackets 23 and 24, and unlocked. Is done. Further, when the front frame 21 is unlocked, the front frame lock claws 2 and 3 are urged in the opening direction by the spring members 14a and 14e, and the pushing portions 2d and 3d of the front frame lock claws 2 and 3 are received by the receiving metal 23, The front frame 21 can be opened easily during the unlocking operation.

  When unlocking the glass frame 22, when the key is inserted into the cylinder lock 9 and the key is turned counterclockwise, the second engaging projection 10b of the cam member 10 is rotated clockwise in FIG. Is moved downward. At this time, the engaging portions 8h and 8i of the operating band plate 8 engage with the engaging portions 6c and 7c of the glass frame lock claws 6 and 7 to push down, and the glass frame lock claws 6 and 7 slide downward. Move. Thereby, the engagement between the glass frame locking claws 6 and 7 and the metal fittings 25 and 26 is released, and the glass frame 22 is unlocked.

  Thus, even if the locking device has the front frame locking claws 2 and 3 that are tilted and locked independently when locking, the locking portions 4a and 5a of the sliding lock members 4 and 5 are locked. Engages with the locking grooves 2c and 3c of the front frame lock claws 2 and 3 to lock the movement of the front frame lock claws 2 and 3, so that the front frame lock claws 2 and 3 are tilted by an unauthorized instrument such as a wire. This is completely impossible, and unauthorized unlocking can be prevented. Further, when a force in the opening direction is applied to the front frame 21 in the locked state, the force is applied to the pivots 2a and 3a of the front frame lock claws 2 and 3 and the engaging portions 4a. Since it is dispersed and applied to 5a, it is possible to increase the locking holding force against the force of forcibly opening the front frame 21, and to prevent unauthorized unlocking.

  Further, the front frame lock claws 2 and 3 are urged in the unlocking direction between the front frame lock claws 2 and 3 and the slide lock members 4 and 5, and the locking portions 4a and 5a of the slide lock members 4 and 5 are urged. One spring member (coil spring) 14b, 14e that urges in the direction of locking is attached.
