[Problem that the invention attempts to solve]

For example, if a key for operating a lock is lost, the lock must be replaced with a new one to prevent misuse of the key.

However, in the prior art, the lock is fixed to the fixed plate, so the lock alone cannot be removed and replaced. For this reason, the entire locking device had to be replaced, resulting in a problem that parts other than the lock were wasted.

Furthermore, when the entire locking device is newly attached to the front frame, there is a problem in that the attachment position of the fixing plate must be adjusted again.
Further, in this case, since the front frame is made of wood, there is a problem in that the taps of the screw holes in the front frame are damaged when the fixing plate is attached and removed.

Therefore, the present invention was developed in view of the above-mentioned circumstances, and its purpose is to eliminate waste by having a structure in which only the lock can be replaced, and to eliminate the need to re-adjust the mounting position of the fixing plate. To provide a locking device for a pachinko machine which can be omitted and furthermore does not damage the tap of a screw hole in a front frame.

[Means for solving problems]

A feature of the present invention to achieve the above object is that a lock mounting hole is formed on the back surface of the fixed plate into which a lock can be inserted from the back surface of the fixed plate, and the lock is inserted into this lock mounting hole so that it can be attached and detached. A support protrusion is provided at a position on the back surface of the fixing plate that does not impede attachment and detachment of the lock, forming an operating claw accommodating gap, and a front frame locking rod and a glass frame locking rod are attached to this support protrusion. The reason is that it is removably attached using the slide attachment part.

[Effect]

To remove the lock from the fixed plate, first remove the front frame locking rod and the glass frame locking rod from the fixed plate by the slide mounting part. Next, remove the lock from the lock mounting hole by loosening the screw. After that, screw a new lock into the lock mounting hole. Next, attach the front frame locking rod and the glass frame locking rod to the fixed plate via the slide mounting part.
