DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a rotary reel driving unit including a rotary reel of a slot machine and a rotary shaft for rotating the rotary reel, and more specifically, a rotary reel and a rotary shaft. The present invention relates to a rotary reel drive unit characterized in that the assembly process is simple and is not easily deformed or damaged.

"Prior Art" (1) Conventionally, a drive unit of a rotary reel has been configured, for example, as shown in FIG. 6 for its perspective view and FIG. 7 for its cross-sectional view.

The rotating reel shown here includes a reel body 30, and a reel boss 20 interposed between the reel body 30 and the output shaft 11 of the motor 10, which is a power source of the reel body 30.

The reel main body 30 has a round tubular shape with a bottom, and is a plastic molded product in which the bottom surface portion and the side surface portion are lightened.
A center hole 31 is provided at the center of the bottom surface portion. A reel tape 90 on which a pattern is printed is attached to the outer curved surface of the reel unit 30. Also, around the center hole 31, the reel boss
Boss fixing holes 32 for fixing 20 are provided at equal intervals.

The reel boss 20 is in the form of a disk having a cylindrical protrusion portion that fits into the center hole 31 of the reel unit 30. The inner diameter of the cylindrical protruding portion matches the outer diameter of the output shaft 11 of the motor 10, and the outer diameter of the cylindrical protruding portion is the center hole of the reel unit 30.
It matches the inner diameter of 31. A tightening hole 21 is provided toward the center of the cylindrical projection portion. The tightening hole 21 may or may not be a female screw hole.

Further, a reel fixing hole 24, which is a female screw, is provided at a position that fits into the boss fixing hole 32 of the reel body 30 when the tubular projection portion is inserted into the center hole 31 of the reel body 30.

A rotary reel is formed by combining the above-mentioned components as follows.

Insert the cylindrical protrusion of the reel boss 20 into the center hole of the reel body 30.
Then, the reel boss 20 and the reel body 30 are fixed by a fixing screw 33 which is a male screw penetrating the reel fixing hole 24 and the boss fixing hole 32.

Next, insert the output shaft of the motor 10 into the output shaft hole 23 of the reel boss 20, and screw in the tightening screw 22, which is a male screw that matches the tightening hole 21, from the tightening hole 21.
By pressing the output shaft to the side opposite to the tightening hole 21 side of the output shaft hole 23 by the tip of 22, the rotary reel including the reel boss 20 and the reel body 30 is fixed to the motor 10.

(2) As another example of the drive unit of the conventional rotary reel, there has been provided such that the reel body and the reel boss are integrally molded with plastic. Side views thereof are shown in FIGS. 8 and 9.

The example shown in FIG. 8 is one in which the tightening hole 21 is formed as a female thread, and the example shown in FIG. is there.

[Problems to be Solved by the Invention] However, the conventional rotary reel drive unit has the following drawbacks.

(1) Since the reel main body 30 and the reel boss 20 are separate bodies in the rotating reel of the above-mentioned conventional example (1), the reel main body 30
The reel boss 20 and the reel boss 20 are fixed by the fixing screw 33, and then the output shaft 11 of the motor 10 inserted into the output shaft hole 23 is fixed by the tightening screw 22.

(2) The reel body 30 is made of plastic, and the tightening holes 21 provided therein are easily deformed or damaged. When deformed or damaged, the output shaft 11 is not completely fixed to the reel body 30, so that the rotation of the motor 10 cannot be transmitted to the reel body 30 well, or the reel body 30 eccentrically rotates. Occurs.

In the above-mentioned conventional example, there is a common cause that the inertial force in the radial direction is applied to the tightening hole 21 via the output shaft 11 and the tightening screw 22 when the motor 10 is started and stopped.

In the examples shown in the above-mentioned conventional examples (1) and (2), when the tightening screw 22 is screwed into the tightening hole 21, deformation or damage is likely to occur.

In the example shown in the above-mentioned conventional example (3), the tightening screw
When the fitting nut 29 suitable for 22 was fitted into the tightening hole 21, it was easily deformed or damaged. Further, the tightening screw 22 may be screwed in while being tilted, or the fitting nut 29 may come out of the tightening hole 21 due to a reaction force from the output shaft 11 generated by the screwing.

The problem to be solved by the present invention is to provide a rotating reel drive unit that is easy to assemble the rotating reel and the rotating shaft and is not easily deformed or damaged.

[Means for Solving the Problems] The present inventor has found that when assembling a rotating reel and a rotating shaft,
Considering a simple assembling means for fixing without using a screw that causes deformation or damage, the above-mentioned drawbacks of the prior art have been solved.
