DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating reel of a slot machine, and more particularly to an improvement of a reference position detecting mechanism for detecting a rotating angle of the rotating reel.

[0002]

2. Description of the Related Art Heretofore, there has been a rotating reel used in a rotating reel unit of a slot machine as shown in a perspective view in FIGS. Conventional rotating reel 10
Is a radial plate 11 having a bearing portion 12 at the center and radially extending around the bearing portion 12, and a cylindrical circle which is bent perpendicularly from the outermost end of the radial plate 11 to form a circumferential surface. Surrounding member 1
3 is formed. Both the radiation plate 11 and the circumferential member 13 are appropriately lightened for weight reduction or the like. For this reason, the rotating reel 10 formed in this manner has a shape like a hollow cylindrical body having a shallow bottom.

A reel tape 19 on which a picture is drawn is attached to the outer peripheral surface of the circumferential member 13. Bearing part 1 of radiation plate 11
Numeral 2 is for fixing the output shaft of the reel motor 30 for rotating the rotating reel 10 in the circumferential direction. The output shaft of the reel motor 30 is a rotating reel 1
No. 0 is inserted and fixed from the side of the circumferential member 13 toward the radiation plate 11 side. The reel motor 30 is fixed to a base plate 50, and the base plate 50 is fixed to a rotating reel unit (not shown). The rotating reel 1
0, the reel motor 30, and the optical sensor 40 are defined as a "rotating reel device".

[0004] Between the bearing portion 12 of the radiating plate 11 and the circumferential surface member, there is provided one reference projection 20 extending in the axial direction perpendicular to the radiating plate 11 and facing the anti-radiating plate 11 side. . The reference protrusion 20 serves as a reference for one rotation of the rotating reel 10. The rotating reel 10 is made of a thermoplastic resin, and is integrally molded including the reference projection 20.

[0005] One rotation of the rotating reel 10 is detected by detecting the presence of the reference projection 20 by an optical sensor 40 fixed separately from the rotating reel 10. The optical sensor 40 used for detecting one rotation of the rotating reel 10 includes:
As shown in FIG. 4, it is fixed to a base plate 50 to which the reel motor 30 is fixed. The optical sensor 40 is not a so-called self-independent optical sensor.
It has a light emitting unit 41 and a light receiving unit 42 facing each other. That is, in the optical sensor 40, the reference projection 20 is
It is fixed to the base plate 50 so as to be located at a position passing through the gap between the light receiving portion 42 and the light receiving portion 42.

[0006]

However, the rotating reel of the conventional slot machine described above has the following problems. Spindle 1 for base plate 50
0, the reel motor 30, and the optical sensor 40 are assembled in the order of the reel motor 30, the rotating reel 10, and the optical sensor 40. This is because the assembling work of fixing the optical sensor 40 to the base plate 50 requires a fine adjustment so that the reference projection 20 is positioned to pass through the gap between the light emitting unit 41 and the light receiving unit 42. The assembly work requiring such fine adjustment is troublesome and troublesome.

If the fine adjustment is not required, the rotating reel 10 can be fixed to the base plate 50 to which the reel motor 30 and the optical sensor 40 are fixed.
However, since the rotating reel 10 is a thermoplastic resin product integrally molded including the reference projections 20, it is inevitable that the positions of the bearing portion 12 and the reference projections 20 are slightly shifted due to molding errors. In some cases, the base plate 5
Adjustment of the fixed position of the optical sensor 40 to 0 could not be completed, and the rotating reel 10 had to be discarded in some cases. Therefore, the reel motor 30, the rotating reel 10
After being fixed to the base plate 50, the rotary reel 10 had to be fixed while being finely adjusted.

If it is possible to provide a rotating reel device capable of adjusting the position of the reference projection after molding the rotating reel, the position of the reference projection may be adjusted after uniformly fixing the position of the optical sensor. Although the point can be solved, no such rotary reel device has been provided. The problem to be solved by the present invention is to provide a rotating reel device that can adjust the position of the reference projection after molding the rotating reel.

And a cylindrical circumferential member 13 forming a circumferential surface. Since the rotating reel 10 requires a stopper, which will be described later, the rotating reel 10 is molded of a thermoplastic resin having appropriate rigidity and elasticity.

Although not shown in detail, the radiation plate 11
The peripheral member 13 is also provided with appropriate lightening for weight reduction and the like. For this reason, the rotating reel 10 formed in this manner has a shape like a hollow cylindrical body having a shallow bottom. An intermediate radiating portion 14 is provided from the bearing portion 12 inside the radiating plate 11 and between the inner surfaces of the circumferential member 13. The intermediate radiating portion 14 has a crank shape whose cross-sectional shape forms an obtuse angle.
