Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine, in which a plurality of rotating members are rotated when the hit ball is won at a specific winning opening, and the symbols shown on the rotating members when the rotating members are stopped. Depending on the combination of, or the state that the game ball passes through the rotating member, the opening time of a specific winning opening is prolonged, or the chance of winning the ball such as repeating the opening is increased, or the hitting ball passes through the rotating member. The present invention relates to an electric accessory device for a pachinko gaming machine, which changes a passing route of a hit ball.

2. Description of the Related Art In a conventional pachinko machine electric accessory device of this type, a rotary member is provided at each of a plurality of shafts that rotate on the same axis at a position visible from the front of the game member. The shaft of each rotary member and the motor corresponding to each rotary disk are connected by a drive means such as a gear mechanism, and each rotary member is driven or stopped by each motor.

[0003]

However, in such a pachinko machine electric accessory device as described above, it is necessary for each rotary member to independently rotate and control stop. On the other hand, since the motor has only one rotary shaft, a motor is required for each rotary member, and thus a plurality of motors are required. As for the number of motors that can be installed close to the same center, up to two motors can be installed with their axes facing each other, but if the number of motors is more than that, installation becomes impossible and rotation of the motors is performed using a drive mechanism such as a gear mechanism. Is required to be transmitted to the rotating member, which has a drawback of complicating the mechanism by such driving means.

Such a complicated mechanism requires a space therefor, which is not only disadvantageous in terms of space, but also has a drawback that the cost therefor becomes expensive. Moreover, since there are a plurality of motors, a space for at least a plurality of motors is required at least, and there is a drawback that the disadvantage in space is further promoted. In a pachinko gaming machine, on the back side of the game board surface, a gutter for guiding the game ball, parts such as a mechanism for various operations by the game ball passing through the gutter are arranged, and the space is increased by the pachinko game machine. Makes the design difficult.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to make a rotor shaft of a rear motor project through a rotor shaft of a front motor so that the rotor shaft protrudes. Since a rotary member that serves as an accessory is attached to the tip of the machine and is directly driven, an electric accessory device for a pachinko game machine that does not require a power transmission member for connecting the rotor shaft of the conventional motor and the rotary member is provided. It will be provided.

[0006]

The electric accessory device for a pachinko game machine of the present invention is intended to achieve the above-mentioned object, and the means includes at least two or more motors arranged at the front and rear, The rotor shaft of the motor is a multi-axis motor configured so as to penetrate through the rotor shaft of the front motor to project, and a pachinko game machine accessory attached to each projecting rotor shaft of the multi-axis motor. And a rotating member that becomes

[0007]

In the electric accessory device for a pachinko gaming machine of the present invention, a plurality of stators are provided on the same axis, and one rotor shaft provided corresponding to each stator is provided on the other stator. Since the hollow shaft of the rotor provided correspondingly is inserted, this motor can be provided with a plurality of shafts on the same axis, and each shaft can be controlled independently, and these stators, Since the rotor can be installed with a small gap in the axial direction, miniaturization of the motor is also achieved.

Since the rotary member is installed on each of the plurality of shafts, each rotary member can be individually controlled by each rotor, and a drive mechanism for transmitting the rotation of the motor is unnecessary. In addition to the fact that the motor is downsized, the installation space on the back surface of the game board can be reduced, and the mechanism for driving the rotating member can be eliminated.
