Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a launching device in a pachinko game machine.

[0002]

2. Description of the Related Art A pachinko game machine plays a game while shooting a game ball to a desired game area of a game board. For this purpose, a ball-hitting coffin that fires a game ball on a game board frame and a driving source thereof are provided. A launch motor, an operation handle for adjusting the hitting force at the same time as activating the launch motor are previously mounted on the mounting base plate, and the mounting base plate equipped with these is composed of a wooden front frame or a game board frame. A structure in which the firing rail is independently mounted via a support member while being mounted on a resin lower frame has been common.

In order to attach the mounting base plate to a wooden front frame or a synthetic resin lower frame constituting a game board frame,
It was attached with many screws. Therefore, the mounting structure using screws or the like not only complicates the assembling process, but also requires the same screw holes to be used again when the firing device is replaced for convenience. As a result, there is a problem that the fixing effect of the screwing is lost. Further, in the conventional structure in which the mounting base plate and the firing rail are separately mounted, it is necessary to check and adjust the ball flying condition.

[0004]

In the conventional mounting structure of a launching device, the frame is made of wooden or synthetic resin, so that the product accuracy cannot be said to be good. When it is stopped, the mounting position is displaced, and in the case of a synthetic resin product, the accuracy of the mounting position does not always match the designed position due to sink marks or the like generated during the molding process.

[0005] When the mounting base plate of the launching device is mounted on a wooden or synthetic resin frame, not only screws are required at many places, but also the number of parts made of different materials is large, so that the acquisition and It requires labor for management, and in the case of screwing, it tends to be out of order, and it is difficult to obtain reliable accuracy. In addition, there is a problem that it is not suitable for recycling due to the large number of parts made of different materials.

The present invention has been made in view of the above-described circumstances,
It is an object of the present invention to provide a pachinko game machine which is easy to manufacture and assemble, has reliable accuracy, is easy to attach and detach a launching device, and is suitable for recycling.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a launching apparatus in which the main function of the launching apparatus is provided in a gaming board frame in which a gaming board which is a target area for launching a game ball fits. As a means to attach and remove the base plate to the game board frame lower frame without tools, as a means to install the launcher base plate mounting holes and multiple mortise holes around the mounting of the game board frame, punching method or in the mold A pachinko gaming machine was formed by simultaneous molding using a molding method of filling and solidifying (for example, a magnesium alloy, a synthetic resin, etc.).

[0008] Further, a game board frame integrally formed in a rectangular shape by left and right side frames, an upper frame, and a lower frame for mounting a game board of a pachinko game machine, and driving means for firing game balls, The launching means, the launching device base plate for mounting the launching ball guiding means, and molding by the method of filling and solidifying in the mold, respectively, as a means for attaching the launching device base plate to the lower frame of the game board frame, At least a launching device base plate is provided on the game board frame, a mounting hole in which a fitting convex portion for incorporating drive means can be fitted, and a plurality of mortise holes at appropriate positions around the mounting hole, by the molding process. When provided integrally,
It is more effective to achieve the purpose.

[0009] In addition, the projecting device base plate is provided with a protruding fitting portion that fits into the mounting hole and a tenon that fits in the mortise hole, and is further mounted so that mounting and dismounting are easy without tools. A pachinko game machine formed by projecting an operation piece and simultaneously molding by a punching method or a molding method of filling and solidifying in a mold (for example, a magnesium alloy, a synthetic resin, etc.) is also more effective for achieving the object of the present invention. .

A molding process is provided on the back side of the base plate of the launching device by projecting a fitting projection that can be fitted into the mounting hole and a tenon that can be fitted into the tenon hole, and at least the tenon is filled and solidified in a mold. If they are formed integrally, it is more effective for achieving the object.

[0011] In addition, as a more effective means for achieving the object, the head of the tenon provided on the back side of the base plate of the launching device is integrally formed by molding with a method of filling and solidifying the head in a mold. On the other hand, the mortise hole provided in the lower frame of the game board frame is formed below the large diameter hole so that the small diameter hole is continuous in the shape of the inverted snow, and the large diameter hole is formed in a size that the head can penetrate. At the same time, the small-diameter hole is formed so that its head cannot be pulled out at the position where the tenon is moved from the large-diameter hole to the small-diameter hole. A plurality of locking pieces having an elastic effect by providing a convex portion and providing an inverted U-shaped slit so as to surround the convex portion are integrally formed at appropriate positions, while a lower frame of the game board frame is provided. On the front side of the lower frame where the projection faces when the launcher base plate is attached to The drilled hole in which the convex portion of the can fitted are formed integrally.

Further, when the launching device base plate is attached to the lower frame of the game board frame, a support rib for supporting the lower peripheral portion of the launching device base plate is set up in a substantially U-shape. It was formed integrally with the lower frame by a molding process using a method of filling and solidifying.

[0013] At least the game board frame and the launching device base plate,
It is more effective to achieve the purpose if they are integrally formed by injection molding of a magnesium alloy.

[0014]

[Operation] A tenon head provided on a launcher base plate provided with a firing function for a large-diameter hole of a reverse snow-polished tenon hole provided on a lower frame constituting a game board frame formed as described above. After fitting, the mortise is moved downward from the large-diameter hole of the mortise to reduce the delicate back-and-forth of the main body of the radiator,
The lower end of the periphery of the launcher base plate is fitted into the substantially U-shaped support rib provided on the lower frame, and at the same time, the projection of the locking piece provided on the launcher base plate having an elastic effect is formed by the lower frame. By fitting into the perforated holes provided in the base plate, subtle vertical and horizontal rattling of the launcher base plate itself can be eliminated. The positioning effect for mounting the base plate is provided. As described above, the present invention is configured such that the launching device base plate can be attached to and removed from the lower frame of the game board frame without tools.

Further, by forming at least the game board frame and the launcher base plate by injection molding of a magnesium alloy, the weight can be reduced without impairing the strength.
