Then, the engagement with the locking piece is released and unlocked.

<Problems to be Solved by the Invention> In the above locking device, when locking, the upper and lower hook members are inserted into the lower side of the locking piece on the main body side, and the upper hook portion of the hook member engages with the locking piece. It is stopped and locked, and when unlocked, the hook member is rotated downward to release the engagement. However, since various metal parts are attached to the front frame of the pachinko machine, it is very heavy, and the front frame attached to the main body via the hinge may shift downward due to its own weight. For this reason, when the position of the front frame is displaced downward, the hook member of the locking device is also displaced downward, so that the hook member that is pivoted downward and unlocked becomes less in a locked state. For this reason, there has been a demand for a locking device that can be unlocked by rotating the key in the same manner as in the prior art, and the hook plate enters and engages from above the locking piece.

The present invention has been made in view of the above points, and has a structure in which a hook member is inserted into an upper side of a main body side locking piece to be locked, and a hook member is rotated upward to unlock. An object of the present invention is to provide a locking device for a pachinko machine that can be unlocked smoothly by rotating a cylinder lock similar to.

<Means for Solving the Problems> In order to achieve the above object, a locking device of a pachinko machine according to the present invention has a vertically elongated base frame formed by integrally molding a mounting plate and a supporting plate into an L-shaped cross section. , Hook plates on the upper and lower parts of the support plate are supported by a rotation shaft with the base of the hook parts facing downward, and the hook plate is rotated with respect to the support plate by an engagement pin and an arc-shaped long hole. And the upper and lower ends of the connecting rods slidably arranged along the inner side of the base frame are connected between the hooks of the upper and lower hook plates and the rotating shaft, and the connecting rods and the base frame A coil spring for urging the connecting rod downward is provided between the bodies, and a cylinder lock is attached to the mounting plate at substantially the center thereof, and a cam plate engaging with a part of the connecting rod is attached to the lock shaft of the cylinder lock. It is a fixed configuration.

<Operation> This locking device is vertically mounted inside the front frame of the pachinko machine, and a plate-shaped locking portion that engages with the hook plate is fixed at a corresponding position on the pachinko machine body side. When the front frame of the pachinko machine is closed with respect to the main body, the upper and lower hook plates enter the upper side of the locking portion on the main body side, and the hook plate biased downward by the coil spring rotates upward, The hook portion rides over the edge portion of the locking portion, and the hook portion of the hook plate is locked by the locking portion and locked.

When the front frame is opened, when the lock shaft of the cylinder lock is rotated by a key in a specific direction, the cam plate rotates while engaging with the connecting rod, and the connecting rod slides upward. At this time, the movement of the connecting rod causes the upper and lower hook plates to pivot upward with the pivot shaft of the base portion as a fulcrum. As a result, the engagement between the hook portion and the locking portion is released, and the front frame can be opened.

When the hook plate is rotated upward by the connecting rod and unlocked, the rotation of the hook plate is guided by the engagement of the arc-shaped long hole and the engagement pin, so that there is no rattling and smoothness. It can be unlocked smoothly by rotating in the disengagement direction. Even if the position of the front frame shifts downward, the hook plate enters from the upper side of the locking part on the main body side and engages with the hook part on the lower side, so the hook plate does not engage.
