Description

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 arrange ball machine, and a sparrow ball machine, and 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 arrange ball machine, a top entrance, a passage,
Along with each game component such as the central winning device, the variable symbol display device, the right accessory operating device for increasing the score, etc., the back cover to cover the game components, relay board, wiring, etc. from the back side of the game board. I am wearing. An inspection window in the shape of a horizontally long rectangle having a receiving frame at the peripheral portion is formed on the rear wall of the back cover, and a window lid 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 lid is opened to inspect the game parts inside through the inspection window, and the game parts are replaced through the inspection window. I am trying to repair it.

[0004]

In the conventional arranging ball machine, a pair of pivots projecting outward in the left-right direction are provided on both sides of the lower portion of the window lid, and a pair of window lids are provided on both sides of the lower portion of the receiving frame. The engaging receiving part that receives the pivot shaft of the above from the bottom side in a detachable manner is integrally formed, and the locking claw that locks the window lid is projected to the rear at the upper end of the receiving frame while the inspection window is closed. Are formed integrally.

When opening the inspection window when inspecting game parts and the like, the locking claw is operated in the detaching direction against its elasticity, and the engagement of the locking claw with the window cover is released. After opening the inspection window by rotating the window cover to the rear around the pivot,
The window cover is removed by pulling out the pivot from the engagement receiving portion. After the inspection, with the pivot of the window lid engaged with the engagement receiving part, rotate the window lid around the pivot toward the back cover, and lock the upper end of the window lid with the locking claw. I try to lock the lid.

As described above, in the conventional inspection window structure, since the window lid is operated in the front-rear direction when the inspection window is opened and closed, for example, by rotating the window lid around the pivot, the back cover rear wall portion is
It is necessary to form a thick receiving frame in the front-rear direction and to project the engaging receiving portion and the locking claw rearward from this receiving frame,
There is a drawback that the size of the inspection window structure in the front-rear direction becomes very large.

Therefore, as the dimension of the inspection window structure in the front-rear direction increases, the bulkiness of the back cover on the rear wall side increases, and as a result, the internal volume of the back cover, particularly the front-rear direction. Since the protruding height of the game board becomes small, it is inevitable that the game components such as the central winning device attached to the game board also have a small amount of projection rearward from the game board.

Further, since the engagement receiving portion and the locking claw are projected rearward from the rear wall portion of the back cover, they are easily damaged,
Not only when assembling, but also when the front frame is opened and inspected after installation at the game shop, there is a risk that the locking claw may be caught and broken. And if these are damaged, the back cover itself is usually fixed to the back side of the game board with nails or the like, and the entire game board unit is discarded.

In view of such conventional problems, the present invention makes it possible to make the inspection window structure thin so as to secure a large internal volume of the back cover, particularly a large protruding height in the front-rear direction, and to prevent damage when the window lid is opened or closed. An object of the present invention is to provide a back cover device for a ball game machine, which can be minimized and can easily open and close the window lid.

Notch 71 to be fitted in and out of the window cover 56
When sliding the lower part along the lid receiving part 70, the engaging claw 65
Is provided with an engaging portion 72 that engages with and disengages freely.

According to a second aspect of the present invention, in the first aspect of the invention, the window lid 56 is raised to the position where the engaging claw 65 corresponds to the notch 71 on the fitting lid 63. At the same time, a stopper 77 that comes into contact with the upper edge of the inspection window 55 is provided.

A locking claw 73 that is engaged and can be detached from the locking portion 66 is provided on the lower edge side of the inspection window 55.

[0013]

[Function] When the inspection window 55 is closed, the engaging claw 65 of the window cover 56 is closed.
Align the notch 71 with the fitting lid 63 side
After fitting with 55, the window cover 56 is slid downward along the lid receiving portion 70 so that the engaging claw 65 engages with the engaging portion 72. Inspection window 55
When opening the window lid 56, when the window cover 56 is slid upward along the lid receiving portion 70, the engaging claw 65 disengages from the engaging portion 72, and the engaging claw 65 corresponds to the cutout portion 71. Stopper 77 at the position
Since it hits the upper edge of the inspection window 55, it suffices to remove the window cover 56 from the inspection window 55.

As described above, the window cover 56 is used as a cover receiving portion of the back cover 23.
With the structure that slides vertically along the 70, the front-back dimension of the inspection window structure can be made thin. Therefore, a large internal volume inside the back cover 23, in particular, a large protruding height from the game board 6 in the front-rear direction can be secured, so that the game board 6
Even game parts with a large amount of protrusion from the rear can be easily mounted, and the game parts to be mounted on the game board 6 can be freely selected.

Further, since the window lid 56 is structured to slide in the vertical direction, it is not necessary to provide the engaging claws 65 and the engaging portions 72 so as to project rearward from the rear wall portion of the back cover 23. It is possible to minimize damage to the engaging claws 65 and the like when the 56 is opened and closed. Further, when opening and closing, the window lid 56 is slid vertically along the left and right lid receiving portions 70 to disengage the engaging claws 65 from the engaging portions 72, so that the window lid 56 can be easily and surely slid vertically. Can be moved. Further, the fitting lid portion 63 of the window lid 56 is fitted to the inspection window 55, but since the fitting lid portion 63 and the non-fitting lid portion 64 are provided in the window lid 56 in a stepped shape, Despite the thin inspection window structure, it is possible to surely close the inspection window 55 with the window cover 56.
