Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine equipped with a ball launching device for launching a pachinko ball.

[0002]

2. Description of the Related Art In a conventional general pachinko machine, a ball launching device for launching a pachinko ball supplied from a bowl is provided on the back side of the front panel provided with the bowl (the front of the main body frame). . This ball launching device has a structure in which main components such as a ball hammer are exposed to the front side when the front panel is opened so that maintenance work such as cleaning, repair and inspection can be performed from the front side.

[0003]

However, since the above-mentioned conventional pachinko machine has a structure in which the main parts of the ball launching device are exposed, the tools, etc. are erroneous during the maintenance work on the parts other than the ball launching device. There is a risk of hitting the main parts of the ball launching device and damaging the main parts. Also,
Falling balls (foul balls) that return to the ball launching device side during a game, or foreign substances that have been dropped carelessly during maintenance work enter the gap in the movable area of the hammer and allow the ball launching device to operate normally. There is also a risk of disappearing.

The present invention has been made in consideration of such circumstances, and therefore an object of the present invention is to maintain the maintainability of the ball launching device while preventing damage or malfunction of the ball launching device due to foreign matter or a falling ball. It is to provide a pachinko machine that can prevent this.

[0005]

In order to achieve the above object, a pachinko machine according to claim 1 of the present invention is provided with a protective cover which is openable / closable or detachable and which covers at least main parts of a ball launching device. It was done. In this configuration, normally, by closing (or attaching) the protective cover, it is possible to cover the main components such as the ball hammer of the ball launching device with the protective cover, so that the tool etc. It is possible to prevent a pachinko ball or a foreign object that has fallen in the vicinity of the ball launching device from falling into a gap in the ball launching device. Then, at the time of maintenance of the ball launching device, by opening (or removing) the protective cover, main parts of the ball launching device are exposed, so that maintenance work of the ball launching device can be performed.

Further, as in claim 2, the protective cover may be provided with a launch passage cover portion which covers at least the lower end portion of the launch passage of the pachinko ball. By doing this, even if the foul ball returns to the lower end of the launch path without falling into the foul ball path, the foul ball will jump out of the launch path by the launch path cover part. It can be prevented and the foul ball can be guided to the firing position.

In this case, if the play of the pachinko balls in the launching passage is large, when the plurality of pachinko balls are accumulated at the lower end portion (above the launching position) of the launching passage due to a foul ball or the like, those pachinko balls are generated. Stacked in a zigzag pattern at the lower end of the launch path. Therefore, even if the bottommost pachinko ball (the pachinko ball at the launch position) is hit with a hammer, it is possible that the striking force is sufficiently exerted in the firing direction on the pachinko balls stacked above in a zigzag pattern. There is a risk that the pachinko balls accumulated at the lower end of the launch passage cannot be launched from the launch passage to the game board surface forever.

As a measure against this, as in claim 3, a ball play restricting rib may be formed on the launch passage cover portion so as to project toward the launch passage and reduce the play of the pachinko ball in the launch passage. . By doing this, when a plurality of pachinko balls are accumulated at the lower end of the launch passage due to foul balls or the like, the pachinko balls can be aligned so as to be stacked almost in a straight line in the firing direction,
The striking force of a batting mallet can be reliably acted on in the launching direction of the stacked pachinko balls, and the pachinko balls accumulated at the lower end of the launching passage can be swiftly ejected from the launching passage to the game board surface.

Further, the play of the pachinko ball is not reduced on the entire inner surface of the launch passage cover portion, but the play of the pachinko ball is reduced by the ball play restricting rib formed on the launch passage cover portion. There is also an advantage that the play of the pachinko ball can be adjusted by only partially correcting the ball play restricting rib portion of the molding die when adjusting the play of the ball to the optimum dimension.
