In the pachinko machine and the arranging ball machine described above, the game board can be put in and taken out of the holding frame on the back side of the front frame regardless of whether the game board is attached or detached in any of the items a and b. The technology that can be simplified was not adopted. Therefore, when attaching and detaching the game board to and from the set opening area of the holding frame, front parts of the respective game boards, mainly the guide rails and surrounding decorative members, and back parts, mainly the ball gathering cover or the collective cover for safe balls are used. Alternatively, the back side parts of the central game parts are directly held to be assembled and set out. However, in such attachment / detachment work, since the entire game board is a considerable weight member, even an expert may be troublesome, and the grasped parts often damage the fingertips.

Further, the following problems are pointed out regarding the technique for fixing the game board in the pachinko machine of the above-mentioned removable front side of the game board. That is, the actual fairness 4-32
139 and the holding device according to Japanese Utility Model Publication No. 61-386
Both of the attachment structures according to Japanese Patent Publication No. 31 can obtain a reliable effect with a simple structure, but since the fixing means is composed of a plurality of members, the number of parts increases and the separated members are easily lost. There was a flaw. Furthermore, each form has a configuration in which the holding member (mounting tool) needs to be mounted on the holding frame in advance, and the holding member (mounting tool) must be mounted from the side opposite to the mounting and demounting direction of the game board. They are common in some respects, and neither of them can achieve simplification and simplification of the game board mounting work. Furthermore, regarding the technology for fixing the game board in the pachinko machine of the detachable type on the rear side of the game board, there are drawbacks that the mounting member has a complicated structure and it is troublesome to assemble it to the holding frame. It was not possible to simplify and simplify the panel installation work.
