The back mechanism set board is detachably attached to the back side of the holding frame in accordance with the attachment / detachment form of the game board to the holding frame provided on the back side of the front frame. There is a type that can be opened and closed, and a type that can be attached and detached. However, in any of the back mechanism set boards, the attachment to the holding frame is performed by a screw attachment mode in which a plurality of screws are exclusively tightened and fixed. For this reason, a special tool (driver or the like) is required when tightening or loosening the screw, and it takes time and effort to assemble or remove the back mechanism set board with respect to the holding frame, which involves unexpectedly cumbersome work. Was.

In the above-mentioned pachinko gaming machine,
For members that require attachment / detachment, such as a ball guide cover for a game board or a protective cover for a back mechanism set board, a commonly used mounting tool other than a screw is a rotating lever shaped to be screwed or shafted.

I have. However, in the above-mentioned tool, even if it is relatively inexpensive, since the engaging force and the tightening force are reduced due to a change over time, it is difficult to stably maintain the members, and a large number of arrangements are required. Conversely, if the tightening force is strengthened, there is an inconvenience that the turning operation of the stopper itself becomes difficult. On the other hand, in the above-mentioned tool, even if relatively stable locking is possible, it becomes unexpectedly expensive because it is a combination tool of two or more parts, and special equipment and tools are required especially for assembling the tool itself to members. In addition, since it cannot be assembled by fingertip operation by an unskilled person, handling is considerably troublesome. For this reason, when the assembling tool is implemented for assembling the back mechanism set board to the holding frame, the same problem as described above occurs, and therefore, it is desired to develop a new form of assembling tool.

Since no tools or the like for rotating the 2, 62 are required at all, the work of assembling and removing the back mechanism set board D can be rationalized and simplified. According to the locking configuration of the key portions 54, 83 and the locking receivers 30, 60 in the attaching / detaching locking devices E, F, the engaging force and the tightening force do not decrease with time, so that they are heavy. Even the back mechanism set board D can be stably fixed and held on the holding frame C for a long period of time.

In each of the detachable locking devices E and F, the locking keys 32 and 62 can be attached to the supporting portions 31 and 61 formed on the back mechanism set board D by one-touch operation. It is possible to easily and easily assemble and support by simple fingertip operation without any need for tools and tools, and rationalization and simplification of assembling work is achieved, including assembling work by unskilled persons.

The locking / unlocking device is not limited to the configuration of the above-described embodiment, and other forms can be appropriately adopted. For example, in the embodiment shown in FIG. 3, a circular shaft hole as a support hole opening is formed in each of a pair of inner and outer support pieces in the support portion, and a locking key is attached to the main body;
And a shaft member having a key formed at one end which can be inserted into a through hole formed in the base of the main body. Then, with the main body of the locking key facing the pair of support pieces, the shaft member is commonly inserted into the shaft hole of the support piece and the through hole of the base, and is prevented from being removed by an appropriate means. Thereby, the locking key is rotatably mounted to the support between the locking position and the unlocking position. However, it is necessary that the main body of the locking key and the shaft member be integrally rotated by means of a key and a key groove. Further, the pachinko gaming machines to which the present invention is applied are not limited to the above-described pachinko machines, but also include other gaming machines such as arrange ball machines and slot machines.
