Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine characterized by a positioning and holding relationship between a game board and a game board holding member (a front frame, a mechanism board, etc.).

[0002]

2. Description of the Related Art A ball game machine 10 shown in FIGS.
In FIG. 1, a positioning projection 106 integrally formed on the back side of the front frame 103 (game board holding member) is inserted into the positioning hole 104 of the game board 105 (see FIG. 12), and
05 is pressed from the back side by a rotatable first lock mechanism 107 and a second lock mechanism 107 '(see FIG. 11). As described above, a plurality of (four in FIG. 11) lock mechanisms are provided along the periphery of the game board 105, and a plurality of cylinder portions of the game board 105 are fixed by the lock mechanism. In addition, there is a ball-and-ball game machine of a type in which a game board 105 is accommodated in a mechanism board.

However, the above-described conventional device requires a large number of lock mechanisms, and has a problem that the number of components is increased. Further, since the number of lock mechanisms is large, many man-hours are required when assembling a ball-and-ball game machine or replacing a game board. Further, when the game board 105 is tilted with respect to the front frame 103, the force required for operating the lock mechanism is not uniform, and there are places where locking is easy and places where locking is difficult, and the workability of attaching and detaching is deteriorated. I do. When the entire game board 105 is floating with respect to the front frame, a large force is required for all the lock mechanisms, and the workability is further deteriorated. As a cause of such tilting or lifting of the game board 105, burrs remaining on the positioning projections 106 during the production of the front frame 103 are considered.

The positioning projection 106 has a function of temporarily supporting the game board 105 in a cantilever manner.
05 cannot be stably supported.
It was not possible to omit the lock mechanism by relying on the positioning projections 106 for the support of 05. In addition, since the positioning projections 106 are hidden by the game board 105 when the game board 105 is assembled, the assembly work is blind.
Workability was poor.
