ILLEGAL OPENING PREVENTING APPARATUS FOR GAME MACHINE

摘要

PROBLEM TO BE SOLVED: To prevent such an illegal behavior as releasing a locked state by forcedly moving a locking member with such an illegal means as putting a wire into the game machine in an illegal opening prevention apparatus for preventing the game machine such as a pachinko game machine, a slot machine installed in a game hall from being opened illegally by using a duplicate key, etc.;SOLUTION: The game machine is provided with an opening and closing door 2 which can be opened with a prescribed key 13, and the locking member 23 which keeps the opening and closing door in a close state on the rear side of the opening and closing door. The locking member is made movable via transmission mechanisms 25 and 26 by energizing an electrical drive source 24 provided on the rear side of the opening and closing door so as to release the locked state of the opening and closing door. A slight play, which prevents the movement of the driven side 26 of the transmission mechanisms from being transmitted to a driving side even though the driven side 26 is moved, is formed in the transmission mechanisms. Thus, when the driving side 25 is not moved due to the play but only the following side is moved in a lock releasing direction, the driven side abuts on a stopper part 35 formed in the transmission mechanisms to block a transmission in an inverse direction.;COPYRIGHT: (C)2004,JPO
