Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game board of a ball game machine represented by a pachinko machine, and more particularly, to a game board of a ball game machine provided with a means for adjusting a launch trajectory of a game ball.

[0002]

2. Description of the Related Art Conventionally, in a ball-and-ball game machine represented by a pachinko machine, a substantially annular guide rail inside and outside is attached to the front of a game board, and a number of game nails and a plurality of winning holes are arranged inside the guide rail. A game area is formed, and a launch trajectory of the game ball is formed such that a launch ball enters the game area from a game ball launching device operated by a player. The launch trajectory of the game ball is generally defined by the exit passage of the hit ball launching device and the guide rail, particularly the outer guide rail.

The game board and the game ball launching device are mounted on the frame of the ball game machine, respectively. When assembling and maintaining the ball game machine, guide rails, which are large parts, are attached to the game board. By fixing the hitting ball launching device to the game machine, the mounting attitude of the hitting ball launching device can be adjusted, so that the launching trajectory of the game ball from the hitting ball launching device into the game area can be adjusted to a good trajectory.

More specifically, a game ball launching device mainly includes, for example, a plunger-type solenoid, and is driven by excitation in accordance with a handle operation of a player, and fires a game ball at a launch speed within a predetermined range. Fire. The plunger-type solenoid is supported at three points on a mounting plate, and the height of the single point on the mounting plate is adjusted by a rotation adjusting member inserted in a wedge shape between the mounting plate and the mounting plate. The launch trajectory can be adjusted almost along the

[0005]

However, in the above-mentioned conventional ball game machine, if the mounting attitude of the guide rail to the game board, especially the inclination with respect to the game board surface, is not appropriate, the game ball may face the front glass. There has been a problem that a stable hit ball cannot be fired by colliding with a window, a collision sound is generated which gives a player an unpleasant feeling, and a glass window or a board of a game board is easily damaged.

On the other hand, if the mounting posture of the guide rail on the game board is adjusted by a mounting mechanism using a wedge-shaped adjusting member as in the above-described game ball launching device, the mounting mechanism is complicated and the mounting is difficult. Because of the space, it is necessary to reduce the size, so the cost is high.
Assembly work on the game board was not easy.

Accordingly, the present invention provides a low-cost ball game machine in which an adjustment mechanism for adjusting the mounting posture of a guide rail on a game board can be easily mounted on the game board, and the launch trajectory of the game ball can be reliably adjusted. It aims to provide a game board.

[0008]

In order to solve the above-mentioned problems, the present invention provides a game area in which an inner guide rail and an outer guide rail are mounted on a plate-shaped game board base, and a game area surrounded by both guide rails. Along with forming a launch path of a game ball to the game area, in a game board of a ball game machine provided with a plurality of game nails in the game area, in the vicinity of the launch path facing the inner guide rail, The outer guide rail is elastically supported on the game board base via an elastic support member that is elastically deformable, and the outer guide rail is plastically deformable between the outer guide rail and the elastic support member. A fixing plastic deformation member for holding the outer guide rail in a fixed position in a state where the support member is elastically deformed is interposed.

In the present invention, the mounting posture of the outer guide rail elastically supported by the game board base via the elastic support member is fixed by the plastic deformation member for fixing.
It is adjusted by plastic deformation of the plastic deformation member for fixing. Therefore, the mounting posture of the guide rail on the game board can be easily adjusted, and the adjustment mechanism can be simply configured by the elastic support member and the plastic deformation member for fixing, so that the guide rail can be easily mounted on the game board. .

[0010] Further, the present invention preferably adjusts an angle formed between an inner peripheral surface of the outer guide rail and a front surface of the game board base near the firing passage by plastic deformation of the fixing plastic deformation member. Is what you do. In this configuration, the required launch trajectory substantially along the board surface can be easily formed by adjusting the inclination of the inner peripheral surface of the outer guide rail near the launch path.

Further, when the outer guide rail and the elastic support member are integrally formed of a resin material, the outer guide rail can be more simply and reduced in the number of parts, and the mounting posture of the outer guide rail can be stably maintained.

Further, according to the present invention, the upper end portion of the inner guide rail allows a game ball to be launched into the game area,
A further configuration of the game board is provided, in which a flap member for preventing return of the game ball from the game area to the launch path is attached and an out port for returning the game ball to the inside of the machine is provided at a lower end portion of the inner guide rail. Can be simplified.

A plurality of the elastic support members are provided on the outer peripheral side of the outer guide rail, and a mounting tab is provided between the plurality of elastic support members and protrudes to the outer peripheral side of the outer guide rail. If a fixing plastic deformation member made of a metal plate is interposed between the tab and the elastic support member, a stable mounting posture can be maintained and a very simple configuration can be obtained.
