DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back cover device for a ball game machine such as a pachinko machine, an arrangement ball machine, a sparrow ball machine and the like, and more particularly to an inspection window structure for a back cover.

[0002]

2. Description of the Related Art In a conventional ball game machine, for example, an arrangement ball machine, an upper entrance port, a pass port,
Attach each game component such as a central winning device, a variable symbol display device, a right character actuation device for increasing the score, and a back cover on the back side of the game board to cover the game components, relay board, wiring, etc. from the back side Is installed. On the rear wall of the back cover, a horizontally long rectangular inspection window having a receiving frame on the peripheral edge is formed, and a window cover is attached so as to openably close the inspection window.

If an abnormality occurs in the game parts, wiring, etc. inside the back cover, the window cover is opened, the inside game parts are inspected from the inspection window, and the game parts are exchanged through the inspection window. To make repairs.

[0004]

In a conventional arrangement ball machine, a pair of pivots projecting outward in the left-right direction is provided on both lower sides of a window cover, and a pair of window covers are provided on both lower sides of a receiving frame. An engaging receiving portion for receiving the pivot of the arm from below is detachably formed, and a locking claw for locking the window cover with the inspection window closed at the upper end of the receiving frame is projected rearward. And are integrally formed.

When the inspection window is opened for inspection of a game component or the like, the locking claw is operated in a detaching direction against its elasticity to release the engagement of the locking claw with the window lid, After opening the inspection window by rotating the window lid to the rear around the pivot,
The window cover is removed by removing the pivot from the engagement receiving part. After inspection, with the pivot of the window cover engaged with the engagement receiving portion, the window cover is rotated around the pivot toward the back cover, and the upper end is locked by the locking claw to lock the window. The lid is locked.

As described above, in the conventional inspection window structure, the window cover is operated in the front-rear direction when the inspection window is opened and closed, for example, by rotating the window cover around a pivot.
A thick receiving frame is formed in the front-rear direction, and an engagement receiving portion and a locking claw must protrude rearward from the receiving frame.
There is a disadvantage that the size of the inspection window structure in the front-rear direction is very large.

[0007] Therefore, the bulk of the rear wall of the back cover increases as much as the dimension of the inspection window structure in the front-rear direction increases, and as a result, the volume inside the back cover, especially in the front-rear direction, is increased. Since the height of the game board becomes small, the game components such as the central prize device mounted on the game board must have a small amount of protrusion backward from the game board.

Further, since the engagement receiving portion and the locking claw project rearward from the rear wall portion of the back cover, they are easily damaged.
Not only at the time of assembly, but also at the time of opening and inspecting the front frame after installation at the game store, there is a risk that the locking claws may be hooked and broken. When these are damaged, the back cover itself is usually fixed to the back side of the game board with nails or the like, so that the entire game board unit is disposed of.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention makes it possible to secure the internal volume of the back cover, particularly the projection height in the front-rear direction, by reducing the thickness of the inspection window structure, and to prevent damage when the window cover is opened and closed. It is an object of the present invention to provide a back cover device for a ball-and-ball game machine in which the window lid can be easily opened and closed as much as possible.
