Abstract

PROBLEM TO BE SOLVED: To prevent the malfunction of a control substrate due to static electricity and to reduce a producing cost by forming a ball guiding path whose end terminal is communicated with a tank rail and which align-guides pachinko balls to a giveaway balls paying device without generating the clogging of balls by reducing ball pressure. SOLUTION: Pachinko balls stored in a giveaway ball storing tank 16 flows out to the ball guiding path 20 through a bottleneck part 18, converts its direction by nearly 360 deg. within a horizontal surface along the path 20, and flows down aligned in two lines to supply for the giveaway ball paying device through the ball flow-in port 22 of a downstream tip. As the flow-out direction is converted by 360 deg. by the path 20 curved like an arc to be guided to the rail 21 like this, the pressure of the flowing-down pachinko balls is reduced at this part to align-guide without generating ball clogging even when the distance of the tank rail 21 is short. Thus, the tank 16 is moved to the side of the bearing part 5 of a mechanism plate 6 to arrange a repeater in a dead space far from the giveaway paying device.

[0002]

2. Description of the Related Art Conventionally, a mechanical plate made of a synthetic resin, which is rotatably supported on one side, is mounted on the back surface of a pachinko machine main body, and the mechanism plate is located on the shaft support side on the back surface. A prize ball dispensing device, a box frame-shaped prize ball storage tank having an open upper surface, and a tank rail for guiding a pachinko ball of the prize ball storage tank to the prize ball dispensing device are provided. The premium ball storage tank and the tank rail are separately formed, and the tank rail is disposed immediately below the premium ball storage tank. By the way, the tank rail plays a role of guiding the pachinko balls of the prize ball storage tank to the prize ball dispensing device without causing the balls to be clogged, and thus considerably reduces the pressure of the pachinko balls which may cause the ball to be clogged. Need a distance of length. Therefore, while providing the premium ball storage tank as far as possible from the premium ball dispensing device, that is, the shaft support side of the mechanism plate,
The outlet of the prize ball storage tank is also kept away to ensure the length of the tank rail.

As a result, a predetermined space is left between the prize ball storage tank of the mechanism plate and the shaft support, that is, above the prize ball dispensing device.
For example, a repeater that relays internal wiring and external wiring of the mechanism plate is attached. A control board on which a power supply circuit, a prize ball circuit, an information circuit, and the like for controlling the prize ball dispensing device are incorporated in the repeater.

[0004]

However, although the space can be effectively used for mounting a repeater, the space is close to a prize ball dispensing device, and the prize ball dispensing device is often used when dispensing a prize ball. Since the static electricity is easily generated due to the friction of the pachinko balls with the resin, there is a problem that the control board in the repeater malfunctions due to the static electricity. In addition, since the prize ball storage tank is disposed as far as possible from the pivot of the mechanism plate, the loads of the myriad pachinko balls stored in the prize ball storage tank act on the pivot as a moment, Therefore, a large load is applied to the shaft support. Therefore, an extra structural design is required in consideration of the strength of the shaft support to withstand the load, and therefore, there has been a problem that the structure of the shaft support is complicated and the manufacturing cost is increased.

Accordingly, the present invention provides a prize ball storage tank which can be disposed closer to a shaft support side of a mechanism plate while maintaining a function of aligning and guiding pachinko balls to a prize ball dispensing device without causing ball jam. A space for installing the repeater is placed at a position away from the prize ball dispenser to prevent malfunction of the control board, and it is manufactured without extra structural design considering the strength of the shaft support of the mechanism plate The purpose is to provide a pachinko machine that can reduce costs.

[0006]

In order to achieve the above object, according to the present invention, a mechanism plate which is rotatably supported on one side is mounted on the back surface of the pachinko machine body, and the mechanism plate is mounted on the back surface of the mechanism plate. A prize ball dispensing device located on the shaft support side, a box frame-shaped prize ball storage tank having an open upper surface, and a tank rail for guiding a pachinko ball of the prize ball storage tank to the prize ball dispensing device are provided. In the pachinko machine, the prize ball storage tank is disposed so as to be closer to the pivot portion side of the mechanism plate, and the inside of the prize ball storage tank is provided between the front and rear side walls of the prize ball storage tank on the side opposite to the pivot portion of the mechanism plate. Providing a constriction with a dimension smaller than the width,
The ball guide path is formed outside the narrowed portion so as to communicate with the tank rail and to form a ball guide path capable of reducing the ball pressure and aligning and guiding the pachinko ball to the prize ball dispensing device without causing ball jam. As described above, since the prize ball storage tank can be disposed closer to the pivot portion side of the mechanism plate, a space for the repeater can be provided by a distance corresponding to the pivot portion, that is, a position away from the prize ball dispensing device. By arranging the repeater, malfunction of the control board due to static electricity can be avoided. Also, the load on the shaft support of the mechanism plate is reduced,
As a result, the structure is simplified and the production cost is reduced.

Further, by forming the prize ball storage tank and the tank rail by integral molding of a synthetic resin, the prize ball storage tank and the like can be easily attached to a mechanism plate and the assembling work can be simplified.
