BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine with an absolute encoder, and more particularly to a novel improvement for changing the reel positioning from a prospective control to a positioning control by using an absolute signal.

[0002]

2. Description of the Related Art As a slot machine with an absolute encoder which has been conventionally used, as shown in FIG. 3, a slot machine is generally formed on a reel along a drive pulse based on the step number and step angle of a step motor. Allocating between each pattern that was done. That is, the patterns are arranged and allocated from a certain reference point on the reel at equal intervals using the basic angle of the step motor, and the reference point uses the ON / OFF signal of the photo interrupter by the protruding slit provided on the reel. A structure, a structure in which an on / off signal generating means is built in a step motor, and the like have been adopted.

[0003]

Since the conventional slot machine is constructed as described above, the following problems exist. That is, the number of pulses for step drive of the step motor is added by passing through one or two reference points on the circumference of the reel, and the predicted position control is performed by the program, so a power failure occurs during control. In the case of step out or malfunction of the motor, the position control of the reel may be impossible or the accuracy may be significantly reduced. In addition, when the above-mentioned malfunction occurs, it causes a serious trouble for the player and the manager due to the nature of the machine called a slot machine.In the past slot machines, measures against such a trouble have been taken. There was no solution.

The present invention has been made to solve the above problems, and in particular, a slot machine with an absolute encoder, in which the positioning of the reel is changed from the expected control to the positioning control by using the absolute signal. The purpose is to provide.

[0005]

A slot machine with an absolute encoder according to the present invention is a slot machine in which a plurality of reels having a plurality of patterns on the peripheral surface are rotated by independent step motors, respectively. Is provided with an absolute encoder, and the position of each pattern is controlled by the absolute signal.

[0006]

In the slot machine with the absolute encoder according to the present invention, since the absolute signal is obtained by the absolute encoder provided in the step motor, the rotation position of the reel can be always observed by this absolute signal. Can detect all abnormalities, power failures, malfunctions, etc., and by outputting an alarm or the like, it is possible to prevent play problems of the slot machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a slot machine with an absolute encoder according to the present invention will be described in detail below with reference to the drawings. 1 and 2 show a slot machine with an absolute encoder according to the present invention. FIG. 1 is a perspective view showing a main part and FIG. 2 is a block diagram.

A reference numeral 1 in FIG. 1 denotes a step motor, and a known absolute encoder 2 is connected to the step motor 1.

A rotary shaft 3 of the absolute encoder 2 is directly connected to a rotary shaft (not shown) of the step motor 1, and a drum-shaped reel 4 is attached to the rotary shaft 3.
, And patterns 5 are formed on the peripheral surface 4a of the reel 4 at a constant pitch.

Although only one reel 4 is omitted in FIG. 1, only three reels 4 are actually arranged side by side, and the step motors 1 are independently coupled to the respective reels 4. .

A control signal 6a of a control unit 6 to which an absolute signal 2a from an absolute encoder 2 is input is input to the step motor 1, and a display unit 7 is connected to the control unit 6.

Therefore, in the above configuration, the absolute encoder 2 has a 6-bit configuration, and the number of patterns 5 is 2.
In addition to one, the reference pattern 5 position is set as zero of the absolute signal 2a.

The reason for using 6 bits is as follows.
21 patterns 5 by dividing 360 ° into 64 as resolution
It is set by saying that 3 times of is 63 and is close to 64.

When the slot machine rotates,
A 6-bit absolute signal 2a is output from the absolute encoder 2. For example, by comparing the stop position on the operation program of the slot machine and the absolute signal 2a with the control unit 6, it is confirmed whether or not there is a malfunction. The display unit 7 can display the contents of the malfunction.

[0015]

Since the slot machine with the absolute encoder according to the present invention is constructed as described above, the following effects can be obtained. That is, as compared with the conventional configuration which is the predictive control, the position (angle) signal composed of the absolute signal is always obtained,
Accurate positioning control can be performed. In addition, since the absolute encoder is used, the position of the reel that actually rotated can always be detected, and by comparing it with the pulse supplied to the step motor, it is possible to control power supply abnormality, rotation abnormality, program abnormality, etc. It is possible to detect abnormalities in the slot machine, generate alarms, and improve the reliability of the slot machine.
