Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko gaming machine, and more particularly to a pachinko gaming machine provided with a guide rail deformation preventing member provided on a game board surface for guiding a game ball into a game area.
[0002]
[Prior art]
Conventionally, a guide rail of a pachinko machine has been formed of a belt-like metal plate having elasticity as is well known, and the guide rail is provided with an attachment hole at an appropriate pitch interval position on one peripheral edge thereof, and By attaching a split pin to the mounting hole and press-fitting the split pin into the game board surface, it is attached in a substantially circular shape on the game board surface at a predetermined mounting angle. However, since the game balls launched from the launch rail always land within the same range of the guide rail, when the pachinko gaming machine is used for a long period of time, the predetermined mounting angle of the guide rail gradually shifts. A situation will occur. In addition, dirt on the inner surface of the guide rail will affect the ball jumping of the game ball, so the inner surface of the guide rail is cleaned relatively frequently, but at this time, the guide rail is deformed outward. It will happen. If the guide rail is misaligned or deformed to the outside in this way, the rolling state of the game ball on the guide rail after the landing range changes, and the game ball enters the game area. There was a problem that the ball fluctuated and a stable ball flying state could not be obtained. Therefore, in order to solve the above problem, the present applicant forms a plurality of support pieces on the mounting base plate of the glass breakage prevention plate as shown in Japanese Patent No. 2926034, and makes the support pieces come into contact with the guide rail. We have proposed a support structure for the guide rail in the pachinko machine.
[0003]
However, the support structure of the guide rail of the pachinko gaming machine according to the above-mentioned Japanese Patent No. 2926034 has a configuration in which the support piece provided on the mounting base plate of the glass breakage prevention plate is completely brought into contact with the guide rail. Although it is excellent in preventing the angle deviation of the guide rail, it has a problem that the range of deflection of the guide rail is reduced.
[0004]
And further research by the present applicants has revealed that even if there is a slight angle shift in the landing range of the game ball on the guide rail, if it can be stopped within a slight range, it will have a significant impact on the ball flight. However, if the deflection of the landing range of the game ball can be maintained in a good state, it has been found that a stable ball flight state can be obtained with no variation in the game ball entering the game area.
[0005]
In addition, the following points have been pointed out as another problem with the guide rails of pachinko machines. That is, since the guide rail is formed of an elastic metal plate, for example, even if an extra force is applied to the guide rail by wiping and cleaning, a force to return to the original by its own restoring force works. become. On the other hand, the part where the split pin of the guide rail is mounted is fixed by the split pin, so that the restoring force does not work, and once the part is deformed due to an extra force applied to the part. It will be in a state of being deformed.
[0006]
[Problems to be solved by the invention]
Therefore, the present invention has been made in view of the above-described problems, and the object of the present invention is to make the pachinko gaming machine used for a long period of time so that the game ball continuously lands within a certain range of the guide rail. Even if excessive force is applied to the guide rail by wiping or cleaning, the angle deviation or deformation of the guide rail is stopped to the minimum range that does not affect the ball skipping of the game ball, and the game A pachinko gaming machine provided with a rail deformation preventing member that can guide the game ball into the game area in a stable state so that the deflection of the guide rail at the time of landing of the ball can be maintained in a good state. Is to provide.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a pachinko gaming machine in which a guide rail for guiding a game ball launched from a hitting ball launching mechanism into a game area is circularly arranged from the lower end to the upper part of the game board surface. A rail deformation preventing member having an arcuate side surface along the lower outer surface of the guide rail and having a plurality of protrusions provided on the arcuate side surface; The rail deformation preventing member is arranged so that a slight gap is formed between the guide rail and the guide rail.
[0008]
Further, it is preferable that at least one of the plurality of protrusions is provided at a position facing the engaging member of the guide rail. In this case, the protrusion is spaced apart from the rear end edge of the arc-shaped side surface of the rail deformation preventing member by a certain distance, has a constant width in a direction perpendicular to the longitudinal direction of the arc-shaped side surface of the rail deformation preventing member, and has a slightly upper end surface. It is good to make it flat. By doing in this way, the bad part by a deformation | transformation can be prevented beforehand about the part which is fixed by the split pin and a restoring force does not act among guide rails.
[0009]
Furthermore, it is preferable to form a guide portion that surrounds the prize ball outlet provided in the front frame body and communicates with the prize ball introduction portion of the hitting ball supply tray in the rail deformation preventing member as described in claim 3. . This eliminates the need to form the guide portion separately from the rail deformation prevention member, reduces the number of parts and reduces costs, and separates the pachinko gaming machine when it is discarded or recycled. Sorting work becomes easy.
[0010]
As a preferred embodiment, the same decoration may be applied to the front surface of the rail deformation preventing member and the front surface of a panel component such as a rail decoration member. As a result, the design of the front surface of the pachinko machine can be made uniform, and the player can be visually attracted.
