Description

[Detailed description of the invention] [Industrial application field] In the invention, a pair of open / close wing pieces are supported on the front and both sides of a ball inlet formed on a mounting plate so as to be able to stand up and tilt freely, and a chucker is mounted below the chucker. Further, the present invention relates to a safe ball receiver for a pachinko machine, in which a box frame is provided on a rear surface of a mounting plate, and an operating member for controlling standing and tilting of the open / close wing piece is supported inside the box frame.

[Conventional technology]

Conventionally, as a safe ball receiver of this kind of pachinko machine,
The mounting plate and the box frame are integrally formed, the chuck is formed separately, and the engaging piece and the engaging portion are integrally connected to each other, or the chuck and the box frame are integrally formed. The one in which the mounting plate is formed separately and integrally connected by the engagement of the engagement piece and the engagement portion is disclosed in, for example,
No. 122787, Japanese Utility Model Application Laid-Open No. 61-103184 and Japanese Utility Model Application Laid-open No. 61-103
It is known from Japanese Patent No. 96972.

However, when the mounting plate and the box frame or the chucker and the box frame are integrally formed of synthetic resin, the surface of the mounting plate is inevitably shrunk or the box frame or the chucker is deformed. In addition, there is a problem that a long molding time is required, thereby lowering productivity and increasing costs.

On the other hand, in order to solve the above-mentioned problems, for example, as disclosed in Japanese Utility Model Publication No. 55-14368, a mounting plate, a chucker, and a box frame are separately formed. I have.

[Problems to be solved by the invention]

However, in the conventional safe ball receiver described above, the chucker is fastened to the front surface of the mounting plate with two screws, and the box frame is further fastened to the rear surface of the mounting plate with two screws to form an integral body. Since the screws are connected, the work of fastening the screws is very troublesome, requiring a lot of labor and time for assembling, and eventually increasing the unit price of the product.

The present invention has been made in view of such problems of the prior art, and the purpose is to form a mounting plate, a chucker, and a box frame separately from each other, and to mold using a synthetic resin. An object of the present invention is to provide a safe ball catcher for a pachinko machine that can facilitate the operation and improve the operation efficiency by eliminating the fastening operation using screws.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention provides a pair of opening / closing wings on both sides of the front surface of a ball inlet formed on a mounting plate, and supports a pair of opening / closing wings so as to be capable of standing and tilting freely. In a safe ball receiver provided with an operating member for controlling the rising and tilting of the open / close wing piece in a rear box frame, the mounting plate, the chucker, and the box frame are formed separately from synthetic resin. In addition, a through hole is formed in both sides of the ball entrance in the mounting plate, and an engaging piece and a rib wall protruding rearward from a side edge of the through hole are formed on the back side of the mounting plate. A U-shaped leg having an engaging portion with which the engaging piece engages and an upward piece abutting on the inside of the rib wall of the mounting plate is formed. An arm rod having a bent portion engaging with the upward piece of the leg portion of the box frame is protruded, and the box frame is applied to the back side of the mounting plate. The engaging piece and the engaging portion are engaged with each other, the chuck is brought into contact with the front side of the mounting plate, the arm rod of the chuck is inserted into the through hole, and the bent portion of the arm rod is inserted into the box frame. The mounting plate, the box frame, and the chucker are integrally connected to each other by engaging with the upwardly-facing piece of the leg.

In order to maintain a stable connection state, it is preferable to form a receiving portion for supporting the rear end of the leg of the box frame on the mounting plate.

Further, in order to ensure the connection by the arm rod of the chucker, a claw-shaped return piece may be formed at the bent portion of the arm rod.

For the same purpose, a protruding edge may be formed on the leg portion, or an elastic piece may be formed.

Further, a slot may be formed in the mounting plate, and a projection may be provided in the box frame to be inserted into the slot.

[Action]

The engaging piece formed on the back side of the mounting plate is engaged with the engaging portion of the box frame, the arm rod of the chuck is inserted through the through hole from the front of the mounting plate, and the bent part of the arm rod is inserted into the box. Lock to the upward piece of the frame leg. Thereby, each member of the mounting plate, the chucker, and the box frame is connected in a body shape without fastening the screws.
