It has become. The base member is provided with a slidable groove for sliding the locking pin, and the locking pin slides in the groove of the base member by rotating the cam member against the urging force.
As a result, the protruding amount of the locking member locking claw portion into the connecting rod through groove portion can be reduced, and the cam member fixed to the cylinder lock shaft is rotated by the rotation of the key inserted into the cylinder lock. The locking pin that is rotated and locked by the cam member slides in the groove provided in the base member. At this time, the protrusion amount of the locking member engaging claw portion is reduced, so that the fitting state with the connecting rod through groove portion is released, and the connecting rod becomes slidable. Also, by returning the key inserted into the cylinder lock to the position where the key can be pulled out, the cam member fixed to the cylinder lock shaft rotates, and the locking pin that has slid the groove of the base member by the cam member is The urging force of the urging member is interlocked with the movement of the cam member. Due to these movements, the lock member locking claw and the connecting rod through groove are re-fitted, and the release is impossible.

In the invention according to claim 4, the two locking pins provided on the lock member are configured in symmetrical positions with respect to the cam member, and when the key inserted into the cylinder lock is rotated in the right direction, The stop pin is operated, and when it is rotated leftward, the lower locking pin is operated. Thus, it is possible to realize a configuration in which the lock can be held and released with a single locking member for the upward sliding and the downward sliding of the connecting rod.

Therefore, the locking device of the general pachinko machine shown in FIG. 1 has a collar member for locking the inner frame, a coupling rod for sliding the same, and a coupling rod for sliding the collar member for locking the front frame or the glass frame. Both connecting rods are slid by a cam member attached to the cylinder lock shaft, and the sliding direction is such that if one slides upward, the other slides downward. It has become. Therefore, the locking claw portion of the lock member is formed so as to lock both of the connecting rod through groove portions, so that the locked state of both sliding can be held and released.

In the invention according to claim 5, the member of the additional or additional device is arranged in the space between the cam member and the cylinder lock mounting base, and does not hinder the function of the gaming machine at all. It is configured. In game machines, a resin cover or steel crime prevention cover has been added to the vicinity of the cam member as a countermeasure against fraud, and a fraud prevention device added to the vicinity of the cam member by these covers. However, in this embodiment, attachment is possible without being affected by these covers.

Therefore, against the act of illegally inserting a wire or the like from the outside, the locking claw portion of the lock member is fitted in the through groove portion of the connecting rod unless the cylinder lock rotates, so that the locked state is maintained. Unauthorized unlocking can be prevented.

According to the addition or addition device for preventing unauthorized unlocking of the gaming machine according to the present invention, a device capable of adding or adding a mechanism for preventing illegal acts without improving or modifying the locking device attached to the gaming machine.
