2. Description of the Related Art As a conventional rotary electric accessory device using a rotary drum, for example, Japanese Patent Publication No. 57-1263.
There is one disclosed in Japanese Patent No. In this device, three rotary drums are attached to a rotary shaft rotated by one motor, and ratchet gears attached to the respective rotary drums are hooked by a tip claw-shaped portion of a solenoid provided on each rotary drum, Each rotating drum is stopped separately. The motor is attached to one side of the case, and the rotary shaft rotated by the motor is supported on the left and right sides of the case.

[0003]

In the conventional rotary electric accessory device described above, since the rotary drum is controlled by one motor and three solenoids, the individual rotary drums are controlled. There is a problem in that the rotation speed of can not be changed freely, and it cannot be stopped at the position of the predetermined symbol.

Therefore, the applicant of the present invention uses a stepping motor, mounts the motor inside each rotary drum, controls the respective motors individually, and controls the stop position of the rotary drum to provide a compact and reliable rotary drum. Has developed a rotating electric accessory that can control

Therefore, the problem is that the rotary electric accessory device must be made compact in order to fit it in the narrow space on the back side of the pachinko gaming machine. Therefore, how to make a compact case The question was whether it would be possible to fix the motor mounted on the support plate and the rotary drum at a fixed interval, and to assemble them accurately and easily.

The present invention is intended to solve the above-mentioned problems. An object of the present invention is to mount a rotary drum on a case by inserting a support plate on which a motor is mounted into a guide groove formed on the case. Therefore, it is an object of the present invention to provide a device for assembling a rotary drum in a pachinko gaming machine, in which the intervals between the rotary drums are constant and the mounting is easy.

[0007]

A device for assembling a rotary drum in a pachinko gaming machine of the present invention is intended to achieve the above-mentioned object, and the means is a rotary drum in which a plurality of types of patterns are drawn on the surface. A motor having the rotary drum fixed to a rotary shaft, a support plate to which the motor is attached, and a case having guide grooves for guiding at least upper and lower sides of the support plate. By inserting the support plate into the guide groove, the rotary drum is positioned and fixed, and when the support plate is assembled in the case, part of the rotary drum is exposed from the case.

[0008]

[Operation] In the device for assembling the rotary drum in the pachinko gaming machine of the present invention configured as described above, each supporting plate is mounted by inserting the supporting plate on which the motor is attached into the guide groove formed in the case. Can be mounted at regular intervals, and a three-dimensional effect can be obtained by exposing a part of the rotary drum from the case.
