[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine provided with a bell that emits a metallic sound when a prize ball paid out from a prize ball paying device collides with the bell.

[0002]

2. Description of the Related Art Conventionally, in this type of bell, as shown in FIG. 3, a screw insertion hole 101 is formed in the center of a bell 100, and a screw 102 is inserted from the screw insertion hole 101 to the screw hole 1 of the plate-like portion 103.
It was screwed to 04 and fixed so as not to rotate.

[0003]

As described above, since the conventional bell 100 is mounted in a fixed state so as not to rotate, the surface is scraped or deformed due to the collision of the prize ball. However, as is well known, recent pachinko machines, such as winning balls that electrically detect a winning ball and activate a variable display device or a special winning opening arranged on the game board to generate a special gaming state. Since many magnetic and optical sensors are used to detect, if the bell 100 is scraped by a collision of a prize ball as in the conventional case, the shavings adhere to the magnetic sensor or the optical sensor and There was a problem that detection was not accurate. Further, the deformation of the bell 100 may reduce or worsen the reverberant sound. The present invention has been made in view of the above-mentioned problems, and an object thereof is to prevent the surface of the bell from being scraped or deformed by rotatably mounting the bell. To do.

[0004]

In order to achieve the above object, the present invention enables a prize ball to come into contact with a prize ball discharge trough that guides the prize ball discharged from a prize ball discharging device to a hit ball supply tray. In a pachinko machine provided with a metal bell, a tubular body having a central hole is formed in the center of the bell, and a screw having a circular shaft portion slightly longer than the tubular body is inserted into the central hole and tightened. By wearing the bell, the bell is attached so as to be rotatable about the circular shaft portion of the screw as a support shaft.

[0005]

When the prize ball paid out from the prize ball payout device collides with the bell, the bell can freely rotate about the circular shaft portion of the screw as a spindle. Therefore, the impact on the bell is reduced, and the surface is not scraped or deformed.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a rear view of a pachinko machine. On the back surface of the pachinko machine 1, a mechanism plate 3 is arranged so as to cover the entire back surface of the game board 2. On the rear side of the mechanism plate 3, a prize ball tank 4 is provided on the upper side thereof, and below the prize ball tank 4, a prize ball lead-out gutter 5 for aligning and flowing down the prize balls is provided. A supply passage 17 is formed on the downstream side of the prize ball outlet gutter 5 via a curve gutter 6, and a prize ball payout device 7 is connected to the lower end of the supply passage 17. Further, below the prize ball payout device 7, there is provided a prize ball discharge gutter 8 for guiding the prize ball paid out from the device 7 to a hitting ball supply plate on the front surface of the pachinko machine 1 (not shown). The bell 9 made of metal is arranged in the prize ball discharge gutter 8 at a position where it can come into contact with the discharged prize ball. The payout of the ball is notified.

Therefore, in the present invention, as shown in FIG. 2, a cylindrical body 11 having a central hole 10 is formed at the center of the bell 9. Further, at the position where the bell 9 is arranged, the screw hole 1 is provided at the center.
The protrusion 13 having 2 is formed integrally with the mechanism plate 3. Then, a screw 15 having a circular shaft portion 14 slightly longer than the cylindrical body 11 of the bell 9 is inserted into the central hole 10 of the cylindrical body 11 and the screw portion 16 of the screw 15 is screwed into the screw hole 12 of the protrusion 13. , Thereby mounting the bell 9 rotatably.

Since the bell 9 thus mounted can freely rotate about the circular shaft portion 14 of the screw 15 as a supporting shaft, the prize ball dispensed from the prize ball dispensing device 7 is a bell 9. When the vehicle collides with the bell 9, the bell 9 freely rotates according to the collision state. As a result, the impact that the bell 9 receives can be reduced, and the situation in which the surface is scraped or deformed can be completely eliminated. The cylindrical body 11 may be made of metal or synthetic resin, but synthetic resin can be manufactured inexpensively.

[0009]

As described above, according to the present invention, since the bell arranged in the prize ball discharge gutter is rotatably attached, the surface of the bell due to the collision of the prize ball. It is possible to solve the conventional problems such as chipping and deformation.
