Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a slot machine, and more specifically, similar to a commonly used slot machine, it is possible to determine how much each reel has rotated from a reference position. This invention relates to a slot machine in which the number of rotations of the motor is detected after passing a reference position, and in which it is easy to replace and adjust the position of a sensor, etc. for detecting passing the reference position. .

[Conventional technology] Conventionally, various slot machines have been provided.

Early slot machines were all mechanically constructed; the reels were rotated by the restoring force of a spring, and when the reels stopped rotating, a number of pin passage holes were drilled in a reference plate fixed to each reel. On the other hand, by applying a pin to this reference plate, the passing pins were mechanically detected, and by determining the pattern, the number of sheets to be piled was determined.

However, with such mechanical slot machines, there is a problem with detection accuracy, especially when the passage hole becomes large after long-term use, which can lead to detection errors.Therefore, in recent years, the reel A protrusion is provided on the inside, and it detects when this protrusion crosses a reference position detection sensor installed near the motor, and also measures how many revolutions the motor for rotating the reel has made after crossing the sensor. By detecting the number of steps of the stepping motor, etc., the pattern at the time of stopping was determined.

[Problems to be Solved by the Invention] However, a slot machine is equipped with at least three reels of fairly large diameter inside the slot machine, and a stepping machine is required to rotate each reel. Three motors were required.

Therefore, the positional relationship inside the slot machine, which has a size limit, becomes extremely complicated, and in particular, the conventional sensor for detecting the reference position as mentioned above is fixed near the motor, and more specifically, the motor is usually fixed to the frame. It was supposed to be installed on a support plate for the purpose of

However, the installation location of such conventional sensors is
In the event that a sensor malfunctions, it cannot be replaced without disassembling the entire reel, and furthermore, it is difficult to adjust the position of the lathe sensor to account for swinging of the reel due to eccentricity of each reel.

Therefore, by fixing the sensor to the frame from the outside, the present invention makes it easier to replace the sensor when it breaks down, and also prevents rotational runout due to eccentricity of the reel when the reel is actually rotated. However, even in such cases, it is possible to easily deal with this by moving the sensor position.Furthermore, even if play occurs due to long-term use, the sensor position can be changed. The purpose is to provide a slot machine that can cope with such backlash by easily adjusting it.

Means for Solving Problem E] In order to achieve the above-mentioned object, the present invention fixes a plurality of support plates to a frame body, fixes a motor and a support plate to each of the support plates, and The reels are fixed to a motor, and when each reel stops rotating, the pattern that appears at a predetermined position on the reel is determined by detecting how much each reel has rotated from its reference position as the motor rotation speed. The slot machine is characterized in that a detection body is provided protruding from the outer periphery of each reel, and a sensor for detecting passage of each detection body is attached to the frame from the outside.

[Example] An embodiment of the present invention will be described below with reference to the illustrated example.

FIG. 1 is a perspective view showing the outline of the present invention, and FIG.
This figure is a schematic diagram of the same, and FIG. 3 is a perspective view showing the reel 10.

In each figure, a slot machine according to the present invention includes a frame body 20 which is inserted into the inside of the slot machine from the outside and is formed as a rotating part to be fixed inside the slot machine, although detailed illustrations are omitted. , three supporting plates 30 fixed to this frame 20, a motor 31 fixed to this supporting plate 30, a reel 10 fixed to the output shaft 32 of each motor 31, and the above-mentioned frame 20. It is formed from a fixed sensor 40.

The frame body 20 is formed so that it can be fixed inside the slot machine by being pushed into the slot machine along a rail (not shown), etc. The frame body 20 has side surfaces made up of a bottom plate 21 and an upright plate 22. It is approximately L-shaped. Further, from the upper end of this standing plate 22, a swash plate 23 is continuously provided in an oblique direction on the bottom plate 21 side.

The support plate 30 includes the standing plate 22 and the bottom plate 2 of the frame body 20 described above.
1 and 1, respectively.

Further, as the motor 31, a stepping motor is normally used, and the ratio of the rotation angle that is less than one rotation from the set rotation position a to the time of stopping can be detected by the number of steps required to make one rotation.

The reel 10 has a fixing portion 11 to the output shaft 32 of the motor 31.
It is formed of a ridge 12 projecting from the fixing part 11 in a direction perpendicular to the output shaft 32 of the motor 31, and a rim 13 provided to continuously fix the tip of the ridge 12 in a ring shape. A plurality of suns 14 parallel to the rotation axis of the motor 31 are projected from each edge 13, and a border 15 is also provided at the tip of each sun 14. Furthermore, such border 13 and border 15
A sheet 17 displaying a plurality of patterns 16 is pasted on each sun 14 located between the two edges, and a detection body 18 is protruded outward from one edge 13. .

Furthermore, the swash plate 23 of the frame 20 has a sensor 4 protruding from the outside of the swash plate 23 toward the reel lO.
0 is fixed. Further, this sensor 40 uses a photosensor consisting of a light emitting part and a light receiving part.

Next, the actual use of the slot machine according to the present invention will be explained.

First, the motor 31 to which the reel 10 is fixed is fixed to the support plate 30, and each support plate 30 is fixed to the frame 20.

After fixing the support plate 30 to the frame body 20 in this way, when the reel 10 is rotated, when the detecting body 18 of the reel 10 that is rotating at that time passes near the swash plate 23, this detecting body 18 The sensor 40 is fixed from outside the swash plate 23 at a position where it will not collide with the sensor 40.

After the sensor 40 is fixed to the swash plate 23 in this manner, electricity is supplied to each stepping motor to actually rotate the reel 10.

The reel 10 that has actually rotated in this manner generates some vibration due to the moldability of the reel 10 itself or deformation during molding.

When the detection body 18 provided on the reel 10 shakes during rotation of the reel 10 in a manner similar to the actual rotation, a sensor is installed that will not collide with the sensor 40 even if the shake occurs. 40 slightly and fix it again in that position.

Note that this movement of the sensor 40 can be done again after an appropriate period of time has elapsed during actual business operations, so that collisions between the detection body 18 and the sensor 40 do not occur.

Furthermore, after being actually used in this manner, the sensor 40 may fail due to some external cause.

In such a case, the frame body 20 with the motor 31 and reel 10 still fixed is taken out from the slot machine, the sensor 40 corresponding to the faulty position is removed from the swash plate 23, and the sensor 40 is replaced with a new sensor 40.
The sensor 40 can be easily replaced by simply attaching the frame 20 to the slot machine again.

Although a detailed explanation will be omitted, 1. For example, by fixing the various wiring etc. for rotating each reel 10 to the surface of the swash plate 23 to which the sensor 40 is fixed, it is possible to prevent the wiring etc. from malfunctioning or from wiring etc. It is extremely easy to replace etc.

[Effects of the Invention] As explained above, the present invention makes it easy to replace the sensor when the sensor breaks down by fixing the sensor to the frame from the outside, and also makes it easier to replace the sensor when the reel is actually rotated. Occasionally, rotational runout may occur due to eccentricity of the reel.

Even in such cases, it is possible to easily deal with this by moving the sensor position, and furthermore, even if play occurs due to long-term use, the position of the sensor can be easily adjusted. Therefore, it is designed to be able to deal with such looseness.
