(Problem that the invention aims to solve) Conventionally, the double cylinder lock, which locks and unlocks the front frame of a pachinko machine to the machine frame and locks and unlocks the glass frame to the window frame, requires installation of the front frame. Because it was fixed to the board with rivets, etc., when the cylinder lock breaks down or needs to be replaced, it is necessary to remove the cylinder lock along with the mounting board from the front frame and replace it, making the operation of attaching and removing the cylinder lock to the front frame extremely complicated. However, there were problems that made it uneconomical.

The purpose of the present invention is to simplify the operation of attaching and detaching the cylinder lock to the front frame.

(Means for Solving the Problems) The present invention has a mounting board attached to the back side of the front frame, which is provided with an interlocking mechanism that can be interlocked with the rotating disc of the cylinder lock attached to this mounting board. In a pachinko machine, in which a movable lock plate having a piece and an operating piece linked to a locking mechanism for locking a glass frame to a window frame are attached so as to be slidable up and down, a part of the mounting board is provided with the movable lock. The object of the present invention is to provide an attachment/detachment device for a cylinder lock in which an insertion portion is formed for inserting a rod-shaped body for temporarily fixing the plate in a state where the interlocking piece is retracted from a position opposing the rotary disk.

(Function) A movable lock plate is attached to the mounting board attached to the back side of the front frame of the pachinko machine so as to be able to slide up and down, and a movable lock plate is formed in opposition to the rotating disk of the cylinder lock for this movable lock plate. The interlocking piece is slid from the position facing the rotary disk to the retracted position, and in this state, a rod-shaped body is inserted into the insertion portion formed in the movable lock plate, and the movable lock plate is supported by the rod-shaped body to form a cylinder lock. Temporarily secure it so that it can be attached and detached.

A substantially triangular plate-shaped rotating plate 11d is fitted into the rearwardly projecting shaft portion 11c of the mounting base 11b, and a first push pin 13A is protruded from the lower end of the rear side of the rotating plate 11d. On the other hand, a second push pin 13B is provided protruding from the upper end of the front side of the rotary plate 11d.

In order to lock the front frame 2 to the machine frame 1, a vertically elongated movable lock plate 14 is attached to the outer surface of the guide portion 5b of the mounting board 5 so as to be able to slide up and down. Guide pins 14a, 14a held between the guide protrusions 6 and the guide protrusions 6, respectively, and protruding near the upper and lower ends of the guide pins 14a, 14a are respectively inserted into the guide holes 7 and guided in the vertical direction. It is always urged downward by a pair of springs 15, 15. At the upper and lower ends of the movable lock plate 14, engaging pieces 14b, 14b are formed which protrude rearward in order to releasably engage with a latch member (not shown) provided on the machine frame 1, and the movable lock plate 14 An engaging portion 14c is recessed in a U-shape on the front edge near the upper end of the movable lock plate 14.
A relief portion 14d is recessed slightly above the central portion of the cylinder lock 1, and a cylinder lock 1 is provided on the rear edge of the relief portion 14d.
An interlocking piece 14e is formed so as to protrude outward from the first push pin 13A of the first rotary plate 11d so as to be able to interlock with the cylinder lock 11 while blocking the rear thereof. When the rotary plate 11d is rotated in the P direction, the interlocking piece 14e is pushed up by the first push pin 13A, the movable locking plate 14 moves upward, and both engaging pieces 14
b and the hooking member are released.

A vertically elongated lock operation plate 16 linked to a locking mechanism (not shown) for locking the glass frame 4 to the window frame 3 is attached to the outer surface of the guide portion 5b of the mounting board 5 so as to be slidable up and down, and is movable with the guide portion 5b. It is interposed between the lock plate 14 and is normally urged upward by a spring 17. A pushing piece 16a connected to the locking mechanism is formed protruding inward near the center of the operating plate 16, and a second pushing piece 16a of the rotating disc 11d of the cylinder lock 11 is provided at the upper end of the operating plate 16. An interlocking piece 16b is provided so as to interlock with the pin 13B and protrudes outward. When the rotary plate 11d is rotated in the opposite direction, the interlocking piece 16b is pushed down by the second push pin 13B, the operation plate 16 is moved downward, and the locked state of the locking mechanism is changed to the state of the push piece 16a. It is released by the downward motion.

An insertion portion 18 formed in the round hole lock is formed on the mounting board 5 in order to temporarily fix the movable lock plate 14 at the upper moving end position where the interlocking piece 14e is retracted upward from the rear of the cylinder lock 11 when the cylinder lock 11 is attached or detached. The guide portion 5b is provided near the upper end of the movable lock plate 14 so as to be opposed to the upper engagement piece 14a, and is movable when the movable lock plate 14 is pushed up to the upper moving end against the elastic force of both springs 15.
