Are shown respectively.

In FIG. 2, numeral 10 indicates a reel unit for a slot machine. The reel unit 10 includes an outer frame 20 having an open front and rear surface and a rectangular cross section, and three rotatable reels 30 that are individually rotatably supported in the outer frame 20 and are arranged side by side.
With. As shown in FIG. 2, in the outer frame 20, a stepping motor for individually rotating the respective rotating reels 30 ...
90 is fixed.

Further, as shown in FIG. 1, reel tapes 50 on which pictures 51 are displayed are wound around the outer peripheral surfaces of the respective rotating reels 30. Further, in the outer frame 20, as shown in FIG.
An optical sensor 60 for detecting passage of the light blocking piece 120 is fixed. The drive of the stepping motor 90 is controlled by the detection signal from the optical sensor 60.

The rotating reel 30 has a central bearing portion 70,
It is composed of a plurality of radiating members 80 extending radially from the bearing portion 70, and a cylindrical member 90 that connects the tips of the radiating members 80 in an annular shape. As shown in FIGS. 1 and 3 to 5, the bearing portion 70 has a disk shape, and a shaft hole 71 for mounting the drive shaft of the stepping motor 90 is formed in the axial direction at the center. .. The shaft hole 71 is formed in a D shape so that its opening cross section corresponds to the cross sectional shape of the drive shaft of the stepping motor 90, thereby preventing the drive shaft from idling.
The shaft hole 71 may have any cross-sectional shape that can prevent the drive shaft from idling, and may have a non-circular shape, for example, a polygonal shape.

As shown in FIGS. 1 and 3 to 5, the radiating members 80 extend radially from the outer periphery of the bearing portion 70, in this case, a total of four cruciform shapes. The middle portion of each radiating member 80 is bent into a substantially crank shape. Further, as shown in FIGS. 1 and 3, one of the four radiating members 80 is provided with a light blocking piece 31 protruding in the lateral direction.
The light blocking piece 31 blocks the light sensor 60 when the rotating reel rotates, and controls the stepping motor 90 by a signal from the light sensor 60 at the time of light blocking.

The cylindrical member 90 has a cylindrical shape as a whole as shown in FIGS. The cylindrical member 90 includes an annular intermediate ring 90 connected to the tip of the radiating member 80, and a pair of left and right side rings 93, 94 connected to the left and right sides of the intermediate ring 90 via a plurality of connecting pieces 92. Has been formed. As shown in FIGS. 3 and 4, the connecting pieces 92 are provided at a position at each tip of the radiating member 80 and in the middle thereof, and a total of eight connecting pieces are provided.

As shown in FIGS. 1 and 3, a plurality of marks 95 for laterally projecting stop positions are formed on the outer edges of the both-sided rings 93, 94 which are opposed to each other. As shown in FIG. 6, the mark 95 for confirming the stop position corresponds to the substantially central position of each pattern 51 displayed on the reel tape 50 attached to the rotary reel 30 and the number of steps of the stepping motor 90 from the central position. The center mark 95 and the side mark 95a displaced by one step from the center mark 95 are arranged at a position displaced by one step.

That is, each pattern 51 is displayed on the reel tape 50 at a predetermined number of steps of the stepping motor 90. More specifically, the reel tape 50 has a total of 2
One picture (51) is displayed. On the other hand, the number of steps of the stepping motor 90 is 400 steps for one rotation. Therefore, one picture corresponds to about 19.5 steps. Therefore, the center mark 95 located at the center of each pattern 51 displays 20 patterns every 19 steps and one pattern at the 20th step.

Therefore, the center mark 95 is the pattern 51.
20 pieces at 16.2 ° intervals and 1 at 18 ° intervals
It is provided individually. The side mark 95a, which is offset by one step from the center mark 95, is formed 0.5 degrees behind the center mark 95 in the rear side in the rotation direction of the rotating reel 30. Further, as shown in FIG. 6, one center mark 95 has a reel tape 50 at a position which is offset by one step between the center mark 95 and the side mark 95a in the front in the rotation direction of the rotary reel 30. One auxiliary mark 95b for confirming the sticking-out position is formed. The mark 9
4 may be either ring 93, 94 on both sides,
It may be formed on the outer peripheral edges of the both side rings 93, 94.

On the other hand, the reel tape 50, as shown in FIG. 6, displays a reference line 52 in the margin for pasting. In addition,
The reference line 52 may be a dotted line or a short broken line. First, when sticking the reel tape 50 to the rotary reel 30, if the reference line 52 of the reel tape 50 is aligned with the auxiliary mark 95b for confirming the sticking-out position, the reel tape 50 can be accurately and quickly stuck to the rotary reel 30. Can be worn. In addition, this attachment is done by reel tape 50 on connecting piece 92.
The reference line 52 of may be combined.

After attaching the reel tape 50, as shown in FIG. 2, the rotary reel 30 is rotatably attached to the stepping motor 90 and mounted on the reel unit 10. In this state, the stepping motor 90 is stopped at a position rotated by a specific number of steps from a predetermined position. The stop position of the stepping motor 90 runs idle due to the inertia of the stepping motor 90 and the rotating reel 30. Therefore, if the idling distance is equal to the predetermined number of steps, the pattern 51 on the rotating reel 30 can be stopped at an appropriate position. However, due to variations in products,
This free running distance may be longer or shorter than usual. Depending on the length of the idling distance, the stop position of the rotating reel 30 may be displaced, and the center of the pattern 51 of the reel tape 50 may not stop at an appropriate position.

In order to determine whether or not the stop position of the pattern 51 is displaced, the distance from the stop position confirmation mark 95 to the specific position when the rotary reel 30 is stopped is determined by For example, by measuring with a method such as applying a reference scale (not shown), it is possible to easily and quickly inspect whether or not the stop position of the rotating reel 30 is displaced.

That is, the rotating reel may be stopped at the center mark 95 having the auxiliary mark 95b. By doing so, it is possible to easily confirm the step deviation of the stop position of the stepping motor 90 by determining which mark 95, 45a, 45b the contact point with the reference scale is. For example, when stopping at the position of the center mark 95, it can be determined that there is no step deviation.
On the other hand, when it stops at the position of the side mark 95a, the stop position of the rotary reel 30 moves backward by 1 in the rotation direction.
It can be determined that there is a step shift. Further, when the rotation reel 30 is stopped at the position of the auxiliary mark 95b, it can be determined that the stop position of the rotating reel 30 is displaced forward by one step in the rotation direction.

Further, since the marks 95 are formed in the number equal to the number of the plurality of patterns 51 displayed on the reel tape 50, it is easy to confirm the stop position of the rotary reel 30. When used for inspection at the factory, it is sufficient to provide only one mark 95 at the stop position after idle running. On the other hand, if the mark 95 is provided at the central position of each pattern 51, it is useful during maintenance. That is, after the slot machine is installed in the hall, it is possible to easily determine whether or not the stop position of the rotary reel 30 is displaced regardless of the stop pattern 51.

The displacement of the stop position of the rotary reel 30 is
