Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the support plate structure of a pachinko machine. To explain in more detail, the present invention is attached to the back side of the front frame of the pachinko machine, and the game board is supported by this support plate. The present invention relates to a support plate structure for a pachinko machine.

[Conventional technology]

As a conventional separate pachinko machine, the game board is divided into an upper board and a lower board, or instead of the game board being divided into an upper board and a lower board, some parts such as a ball launcher rail are added. A device is known in which a game board is placed on the upper end of a support plate made of synthetic resin.

As shown in FIG. 12, in the conventional configuration in which the lower end of the game board 4 is placed on the upper end of the support plate 1, the prize ball outlet 3 is formed on one side of the upper part of the support plate 1 by the cylinder upper part 3c. was. The terminal end of the cylinder upper part 3c prevents the unauthorized member S3 from being inserted through the gap S4 formed between the back side of the game board 4 and the lower end 5a of the connecting gutter 5.

[Problem that the invention attempts to solve]

However, in any of the above cases, the boundary between the upper board and the lower board, or the boundary between the play board and the support plate, is simply formed in a straight line and horizontally separated, so each border can be seen from the front. It's clearly visible when you look at it. Usually, a tamper-proof structure is adopted to prevent unauthorized parts such as cell boards and piano wire from entering by using a metal frame provided on the front frame, a glass door frame, and a front plate. As shown, the unauthorized member S3 can be inserted from the prize ball inlet S2, which is the upstream opening of the prize ball storage tray S1 provided on the front plate. However, the conventional prize ball outlet 3 is formed with a cylindrical upper part 3c, and although it was possible to prevent fraud by inserting the unauthorized member S3 from the inner end of the cylindrical upper part 3c to the back side of the game board 4, Since there is a gap S5 at the boundary between the support plate 1 and the support plate 1 when viewed from the front, it has been impossible to prevent unauthorized insertion of an unauthorized member S3 through this gap S5.

When the fraudulent member S3 is inserted into the back side of the game board 4, the prize ball ejection movement rod 20a and the connecting rod 20b formed on the mechanism plate 20 arranged on the back side of the game board 4 are activated.
(as shown in FIG. 4) or by operating the operating mechanism of the winning ball device protruding from the back of the game board 4 to fraudulently obtain prize balls.

That is, in the state shown in FIG. 12, a gap is created between the back side of the game board 4 and the rear end 5a of the connecting gutter 5.
A fraudulent component S3 was inserted from there, and a fraudulent act was carried out.

In order to prevent the above-mentioned fraudulent acts, the present invention erects a standing wall or the like on the front side periphery of the prize ball outlet related to the prize ball inlet, so that the border between the game board and the support plate can be seen from the front. It is hidden to prevent unauthorized parts from entering, and a cylindrical part is provided to protect the surface of the game board.
The gap on the back side of the standing wall is eliminated to prevent unauthorized parts from entering.

[Means for solving problems]

The present invention has been made in view of the above-mentioned problems, and is a support plate that is attached to the back side of the front frame of a pachinko machine, the support plate is formed of a synthetic resin material, and the ball is placed on the entire surface of the support plate. A launch rail attachment part is formed, and a prize ball outlet is formed protruding from one side of the upper part, and the prize ball outlet is formed by a cylindrical part having a width substantially the same as the depth of the support plate, and the prize ball outlet It is characterized in that a standing wall is provided on the periphery of the front side of the opening of the ball outlet.

[Effect]

According to the present invention, a prize ball outlet is integrally formed on the support plate, and the prize ball outlet is formed by a cylindrical portion having a width substantially the same as the depth of the support plate. A standing wall is erected from the front side periphery of the opening of the outlet, making it impossible to insert illegal parts from the prize ball outlet into the front and back sides of the game board.
Unauthorized gaming can be prevented.
