Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball rebound device for a pachinko machine that rebounds a ball flowing in the direction of the outlet along a guide rail toward the center of the game area.

[0002]

2. Description of the Related Art FIG. 5 shows the front of a game board 51 which constitutes the main body of the game of a conventional pachinko machine, and a ball emitted from a ball launching device is provided with inner and outer bands 52; 5 provided on the game board 51.
A game area 5 surrounded by inner and outer bands 52 and 53 by pushing and opening a preventive valve 54 called a return ball preventive valve from between 3
When the ball is fired at 5, and the momentum of the fired ball is strong, the ball flies along the outer band 53 and collides with the reaction body 56 made of an elastic body such as rubber or soft synthetic resin, and the reaction body 56 is By bounced back the colliding ball toward the upper center around the nails 57 and the center ornament 58 in the game area 55, the ball that is vigorously launched into the game area 55 is moved to the outer band 5
It is designed to prevent the vehicle from going directly to the outlet 59 along the line 3.

[0003]

However, in the above-mentioned conventional example, the reaction body 56 has a structure in which the reaction body 56 is fixed to the board surface decoration 60 attached to the game board 51 so as to surround the game area 55 with the set screw 61. If the body 56 is too hard, the reaction body 56 bounces the ball with a strong force, and the ball with strong momentum causes the reaction body 56 to move.
There is a problem that the nail and the synthetic resin parts are damaged by repeated collisions with surrounding nails and the synthetic resin parts, and when the reaction body 56 is too soft, the ball is properly moved toward the upper center. There was a problem that it could not bounce.

Therefore, the present invention provides a ball bouncing device for a pachinko machine capable of appropriately compensating the hardness of the reaction body.

[0005]

According to the present invention, a reaction body that rebounds a ball flowing in the direction of the outlet along the guide rail toward the center of the game area is provided so as to be elastically movable with respect to the game board. Therefore, for example, in the case where the reaction body is formed of a conductive rubber or a soft synthetic resin, the elasticity of the reaction body is a non-conductive rubber because the static electricity generated between the ball and the ball is released by the reaction body. Or, even if it becomes harder than that made of soft synthetic resin, the impact received from the ball can be absorbed by the elastic movement of the reaction body, and the reaction body can appropriately bounce the ball toward the upper center of the game area. Also,
Even if the elasticity of the reaction body is soft, the softened elasticity can be supplemented by the elastic movement of the reaction body, and the reaction body can appropriately bounce the ball toward the upper center of the game area. Further, in the present invention, if the reaction body is supported on the game board by the elastic body, the elasticity of the reaction body and the elasticity of the elastic body can be organically combined. Further, in the present invention, if the reaction body is formed in a hollow shape, the elastic body becomes unnecessary,
The number of parts can be reduced.

The inner and outer bands 7; 6 form a guide rail, and the inside surrounded by the guide rails on the design board surface of the game board 2 is a game area 17 (the game area 17 is similar to the game area 55 in FIG. 5). The decoration base 4 is provided with a plurality of protrusions 8 and spring receiving portions 9. The plurality of protrusions 8 correspond in position to the openings 10 cut out in the decorative cover 5 for disposing the reaction body 11 of the ball-bounce device 1. The height T of the protrusion 8 is the reaction body 1.
The upper surface of the projection 8 is formed with a prepared hole 12 which is recessed inward and has a size higher than the thickness t of 1. Through holes 13 are formed in the decorative cover 5. When the decorative cover 5 is attached to the decorative base 4, the through hole 13 corresponds to the prepared hole 12 of the protrusion 8. The spring receiving portion 9 is arranged at a position covered with the decorative cover 5. The reaction body 11 has a plurality of elongated holes 1 penetrating vertically in a block body made of rubber or soft synthetic resin.
