Abstract

PURPOSE: To provide a reel controller for a slot machine capable of accurately detecting a rotating pattern, reducing the number of parts and time for working for detection, reducing a fault and a reading error and furthermore, accurately stopping the pattern at a prescribed position of a reel window. CONSTITUTION: A slit 2b corresponding to the pattern and a strobe hole 2a to detect the position are formed inside/outside an annular plate body 2 mounted on the side face of a rotary reel 1 in the circumferential direction. A photosensor 5a detects the strobe hole 2a, and a photosensor 5b starts to read the slit 2b at the timing of a detection signal. A read timing is set to the driving pulse of a stepping motor which drives the rotary reel 1. The slit is read and a pattern signal is outputted bit by bit every output of the driving pulse. When a player depressed a stop button, a stopping signal is outputted, however, when a strobe signal is outputted after the stopping signal is outputted, the rotary reel 1 stops at that time.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to symbol detection and rotation stop control of a rotating reel of a slot machine.

[0002]

2. Description of the Related Art As a symbol detection device for a rotary reel relating to the symbol detection of a slot machine, a plurality of holes are formed in a detection disk that rotates in association with the rotary reel, and the presence or absence of the holes is determined by using a light emitting element and a light receiving element. Most of them check. One of the rotation counting methods is to make holes corresponding to the number of symbols near the outer circumference of the detection disk at equal intervals and detect the symbols by the number of counts from a reference hole. However, if you stop in the middle of the design, the design will be 1
There is a case that the symbol detection device and the actual symbol display may deviate from each other.

Another stop detection method is to identify a symbol by detecting an arrangement of a plurality of holes perforated in a radial direction for one symbol, but cannot be detected unless the rotating reel is stopped. There is a drawback that.
Proposals to improve the drawbacks of these symbol detection devices,
Japanese Utility Model Publication No. 61-31184 and Japanese Utility Model Publication No. 63-2495.
No. 0 publication.

FIG. 14 shows a symbol detecting device proposed in Japanese Utility Model Publication No. 63-24950, in which a strobe through hole 22 for position detection and an array through hole 23 for symbol detection are provided on the side surface 21a of the rotating reel 21. It is provided. Strobe through holes 22 corresponding to 21 symbols on the peripheral surface 21b of the rotary reel 21 are formed near the peripheral edge of the side surface 21a. The array through holes 23 are arranged in a line between the shaft 24 and the strobe through holes 22. 1
For one symbol, one strobe through hole 22 and five array through holes 23 are formed. Stop plate 25
Is provided for accurately stopping the symbol on the peripheral surface of the rotating reel 21 at a predetermined position of the reel window.

The detection method of this pattern detecting device is to read the array of array through holes 23 at the timing of the strobe signal emitted from the light receiving element when the light passing through the strobe through holes 22 is sensed, and at the same time, to read a specific strobe through hole. The number of passages from 22 is counted.

[0006]

However, in the above-mentioned symbol detecting device, the possibility of erroneous counting, which is a drawback of the rotation counting method, cannot be denied, and the detection of symbols during rotation cannot be said to be certain. It was Further, as the number of through holes for detection increases, it takes more time to detect the parts, attach the parts, and work on the through holes, and there is a problem that failures and reading errors increase. Further, there is a problem that the stop plate may be worn or damaged.

The present invention was proposed in view of the above problems, and accurately detects a rotating pattern, and
It takes less time to detect parts, their mounting, and machining of through holes. Moreover, there are few failures and reading errors. Furthermore, without a stop plate, the symbol stops accurately at a predetermined position on the reel window. An object is to provide a reel control device.

[0008]

In order to solve the above-mentioned problems, a reel control device for a slot machine according to a first aspect of the present invention rotatably pivots a plurality of reels having a plurality of symbols on its peripheral surface, In a slot machine in which the symbols are arranged so as to be close to the reel window, and a game is played by a combination of symbols aligned in the reel window when the reel stops rotating, the detection plate interlocked with the pivotally supported reel is provided. Providing strobe detection means for detecting a strobe pattern provided corresponding to the symbol and outputting a strobe signal,
The strobe signal is read based on a stop signal output by a stop button to stop the rotation of the reel so that the symbol is stopped at a predetermined position of the reel window.

The interlocking detection plate may be attached to the reel unit.

Further, the reel control device of the slot machine according to claim 2 rotatably supports a plurality of reels having a plurality of symbols on the peripheral surface, and the symbols are arranged so as to be close to the reel window. In a slot machine configured to play by a combination of symbols aligned in a reel window by stopping rotation of the reel, a pattern pattern and a strobe pattern corresponding to the symbols are circumferentially arranged on a detection plate that is interlocked with a pivotally supported reel. A strobe detecting means for detecting a strobe pattern of a rotating reel and outputting a strobe signal, and a symbol reading means for reading a symbol pattern based on the strobe signal and outputting a symbol signal are provided.

Further, in the reel control device of the slot machine according to claim 3, in the reel control device according to claim 1, a stepping motor is used to drive the reel.

Further, in the reel control device of the slot machine according to claim 4, in the symbol reading means according to claim 2, the symbol pattern is read based on a clock pulse for controlling the rotation of the stepping motor for driving the reel. Means were used.

[0013]

In the reel controller of the slot machine according to the first aspect, when the stop button is pushed, the stop signal is continuously output. After the output of the stop signal, the strobe pattern to be read first is detected, and when the strobe signal is output, the rotation of the reading reel is stopped at the rising time or the falling time of the output. At this time, the symbols on the peripheral surface of the reel stop at a predetermined position of the reel window.

Further, in the reel control device of the slot machine according to the second aspect, the strobe detecting means detects the strobe pattern of the detection plate interlocked with the rotating reel and outputs the strobe signal. Based on this strobe signal, the symbol reading means reads the symbol pattern,
Outputs a symbol signal.

Further, in the reel control device of the slot machine according to the third aspect, when the strobe signal is output by the strobe detecting means after the stop signal is output, the stepping motor is driven at the rising time or the falling time of the output. The output of the clock pulse is controlled to stop the reel after the set time.

Further, in the reel controller of the slot machine according to the fourth aspect, the symbol reading means reads the symbol pattern based on the clock pulse for controlling the rotation of the stepping motor for driving the reel, and outputs the symbol signal.

1 to 3, reference numeral 1a denotes a support 1b.
The synthetic resin reel main body supported by 1., 2 is an annular plate attached to the side surface of the reel main body 1a, 3 is a symbol sticker attached on the peripheral surface of the reel main body 1a, and the rotary reel 1 has these three It is composed of members. Reference numeral 5 denotes a detection unit using two sets of photosensors each including a light emitting diode and a phototransistor.
Is provided with a photo sensor 5b on the inner peripheral side and is attached to the mounting frame 4 by L
It is attached with a metal mold 5c. Reference numeral 6 denotes a 4-phase 4-pole stepping motor which is mounted on the mounting frame 4 and which has a step angle of 1.8 degrees and a circumference of 200 divisions. Drive control IC for controlling the rotation speed of the stepping motor 6
Keeps the rotating reel 1 at 75 rpm in the steady state,
It is controlled by a clock pulse output from the processing unit 10 of the slot machine main body. Reference numeral 7 denotes a circular metal fitting for attaching the rotary reel 1 to the rotary shaft 6a of the stepping motor 6. Reference numeral 8 is a reel window in which the design of the design sticker 3 attached to the rotary reel 1 can be seen, and three horizontal lines L1, L2, L3 and two diagonal lines are carved on the window surface. Three reels including the reel 1 can be seen from the reel window 8.

Here, the rotary reel 1 is a reel, the annular plate 2 is a detection plate, the symbol sticker 3 is a symbol, the photosensor 5a of the detection unit 5 is strobe detection means, and the photosensor 5b of the detection unit 5 is. It corresponds to the symbol reading means.

As shown in FIG. 4, the annular plate 2 is divided into 20 equal parts in the circumferential direction, and a strobe hole 2a for detecting the position of the symbol is recorded in each frame, and the symbol information is recorded. The slit 2b is provided. In addition, the symbol sticker 3 of the rotating reel 1 is also divided into 20 frames equally divided in the circumferential direction.
Types of patterns A, B, C, D are regularly arranged and printed. In FIG. 4, the symbol A is the line L1 of the reel window 8.
At the position of, the pattern D appears at the position of the line L2, and the pattern C appears at the position of the line L3. On the other hand, the detection unit 5 for detecting the symbol appearing on the reel window 8 is attached at a position forming an angle of 90 degrees with the horizontal line L2. Therefore, design A
Slit information A'corresponding to is 9 from the pattern A when rotated.
It is 0 degrees behind. Similarly, the slit information B ′, C ′, D ′ corresponding to the symbols B, C, D is also the symbols B, C, D
They are 90 degrees behind each other.

Here, the annular plate member 2 of the rotary reel 1 will be described in detail with reference to FIGS. First, FIG. 6 is shown in FIG.
7 is a partially enlarged view of the slit information C ′ in which the symbol information of FIG. 7 is recorded, and FIG. 7 is a time chart showing the output of each signal when each unit of FIG. 6 passes the detection unit 5. The timing T1 in FIG. 7 indicates the point in time when the point P1 in FIG. 6 passes the detection unit 5.

As described above, since the symbols provided on the peripheral surface of the rotating reel 1 are 20 frames, the occupied angle of one symbol is 18 degrees as shown in FIG. Since the strobe hole 2a is half of this, it is 9 degrees. Furthermore, this strobe hole 2a
Slit 2 for every 1.8 degrees that divides the occupation angle into 5
There is a space for b. The slit 2b is a slit for recording a symbol signal. This slit 2b is 5
If both are used, it is possible to engrave 5 bits (2 ⁵ ) or 64 kinds of information. In the first embodiment, only 4 types of symbols are used, so 2 bits are enough, but in order to correspond to 8 types of rotating reels, 3 bits of information are actually used.

The clock pulse is generated by the stepping motor 6
In order to maintain a constant 75 rpm rotation, 4 msec from the processing unit 10
It is output at intervals. The stepping motor 6 advances by 1.8 degrees with one clock pulse.

At timing T1 in FIG. 7, the photosensor 5a on the outer peripheral side detects the strobe hole 2a and outputs a strobe signal, and at the same time, the photosensor 5b on the inner peripheral side detects the slit 2b of the slit information C '. The first bit of the symbol signal is output. The next clock pulse output 4 msec later outputs the second bit pulse of the symbol signal. Furthermore, the pulse of the third bit of the symbol signal is output after 4 msec. Since there is no slit at the positions of the 4th and 5th bits, naturally no symbol signal is output. Thus, 12 ms from the rising edge of the strobe signal at timing T1
At timing T2 after ec, the reading of the slit information is completed. Here, the symbol signal c [binary code 111] corresponding to the symbol C is detected. The strobe signal is turned off at timing T3 8 msec after that, and the off state continues for 20 msec. And 40 msec from timing T1
One symbol ends at a later timing T4.

At the same time, at timing T4, the photo sensor 5
a detects the strobe signal of the next symbol A, the photosensor 5b reads the slit information D'of the symbol D from it, and the detection unit 5 outputs the symbol signal d [binary code 100] corresponding to the symbol D. . Ring plate 2 of rotating reel 1
Is formed as described above. The above-mentioned time of 4 msec is determined from the time required for the signal processing circuit to read the slit information, and it goes without saying that if the read signal can be processed at high speed.
In addition, the symbols of 20 frames on the peripheral surface of the rotating reel 1 are all different from symbol a to symbol ne, and an example of a case in which it is represented by binary code as 5-bit slit information is shown in the table of FIG. It was

Next, the reel stop operation of the rotary reel 1 of the slot machine of FIG. 1 will be described with reference to FIGS. 4 and 5. First, in the slot machine, the customer stops the three rotating reels rotating at high speed by the stop button 9, and the arrangement of the symbols displayed on the reel window 8 at that time causes a predetermined number if the winning symbol arrangement. Will be paid out. For example, the winning symbol arrangement of the slot machine of FIG. 1 has a horizontal line L1 · L drawn on the reel window 8.
Judgment is made according to the arrangement arranged on any one of 2 · L3 and diagonal lines. Therefore, the customer looks at the rotating design and presses the stop button 9 to stop the design as desired. The stop signal of FIG. 5 is output from the moment the stop button 9 is pressed.

There are three control methods for the stop control of the rotating reel 1 when the stop signal is output. One detects the design in which the stop button 9 has been pressed (hereinafter referred to as the relevant design), checks whether it is a winning design that becomes a winning design arrangement, and if it is a winning design, the design to stop at that position It is a designated control. In other words, at the fall of the strobe signal, if there is a stop signal and a hit symbol signal described later, the rotating reel 1 is stopped there. The winning symbol is stored in the memory 10a.

One is a position designation control for stopping at a symbol a designated number of frames ahead of the symbol, counting the number of rising edges of the strobe signal in a state where the stop signal is continuously output, and a predetermined number of frames. The rotating reel 1 is stopped at the fall of the strobe signal of the previous frame. 1
One is a random control to stop at the falling edge of the first strobe signal from the symbol, regardless of the timing at which the stop button 9 is pressed, to stop the rotating reel 1 at the falling edge of the first strobe signal from the time of pressing. It is a thing. Therefore, the stop button is pressed to stop at the symbol or the next symbol.

In the first embodiment, the reel stop device will be described with symbol designating control. The same applies to other stop control methods. Here, the rotary reel 1 of FIG. 4 represents the state of the timing D7 of the time chart of FIG. 5 in which the symbol is the symbol D and the strobe signal output of the symbol signal D ′ is completed. Now, if the design of the reel 1 at the right end is the design D, a large payout can be expected. The payout rate of the slot machine 1 is currently less than 100%,
It is controlled by the processing unit 10 so that the winning combination is obtained as much as possible.

The timing T1 in FIG. 5 indicates the passing point of the point P1 at the boundary between the symbol C and the symbol D, which is one and a half frames (27 degrees) before the symbol in FIG. 4, and the timing T1. From T to T4 are the same as those in FIG.

The reel controller of the first embodiment takes two operations, mode 1 and mode 2, depending on the timing at which the stop button 9 is pressed. Mode 1 is an operation when the stop button 9 is pressed before the center of the symbol passes through the line L2 from the lower end of the symbol, and mode 2 is after the center of the symbol passes the line L2. This is the operation when the stop button 9 is pressed before the upper end of the design passes there. Here, the timing up to T4 is the same, and since it has been described above, it will be briefly described.

The symbol signal c is read between the timing T1 and the timing T2, and it is judged that the symbol C has moved to the position of the horizontal line L2 of the reel window 8. This symbol signal is stored in the memory 10a of the processing unit 10 until the next symbol signal is detected. At timing T3, the pattern C is at the center position of the horizontal line L2.

In other words, the mode 1 is a mode when the stop button 9 is pressed while the strobe signal is being output. During the period from timing T4 to timing T6, the next symbol signal d is detected and stored in the memory 10a in place of the symbol signal c. Within a margin time of 8 msec from timing T6 to T7, collation with the winning symbol (in this case, symbol D) stored in the memory 10a is performed, and if it is a winning symbol, a winning symbol signal is output. On the other hand, at the timing T5, the stop button 9 is pressed and the stop signal is output. When the strobe signal falls at the timing T7, the presence or absence of the stop signal and the hit symbol signal is checked. Since the winning symbol signal is output by the timing T7, the output interval of the clock pulse is immediately adjusted, and the rotating reel 1 finally stops smoothly at the timing T8. After the rotation reel 1 is stopped, the stop signal is reset at timing T9. In this way, the rotary reel 1 always stops at a predetermined position. If the payout is too much at this time, stop before the symbol D so as not to arouse gambling.

In other words, the mode 2 is a mode when the stop button 9 is pressed while the strobe signal is not output. After the strobe signal is turned off at the timing T7, the stop button 9 is pressed at the timing T10, and the stop signal is output. Timing T1
Even when the strobe signal rises at 1, the presence or absence of the stop signal and the hit symbol signal is checked. At this point, if the stop signal and the hit symbol signal are confirmed, the next symbol signal d
Continues to output clock pulses until is output. When the symbol signal d is detected at the timing T12, the output interval of the clock pulse is adjusted at the falling edge of the strobe signal at the timing T13, and the rotary reel 1 finally stops smoothly at the timing T14. After the rotation reel 1 is stopped, the stop signal is reset at timing T15. In this way, the rotary reel 1 can be stopped by designating a symbol. The strobe signal and the symbol signal in FIG. 5 represent outputs in the mode 2.

At the above-mentioned stop position, the pattern goes a little over the line L2, but this is because the strobe pattern is shortened or the mounting position of the detecting portion 5 is adjusted by the time required for the stop to bring it closer to the reel window. It can be solved by installing it.

The strobe signal does not necessarily have to be half of one symbol occupation time, and may be shortened or lengthened depending on the processing capacity of the processing unit. Further, as shown in FIG. 9, a strobe hole 2c may be provided in the radial direction of the set position of the slit 2d, and the slit 2d may be read at the timing of detecting the strobe hole 2c to output a symbol signal. At this time, a motor other than the stepping motor can be used as the motor for driving the rotating reel. Further, as shown in FIG. 10, a slit 2f may be provided subsequent to the strobe hole 2e to read the design.

Further, the strobe holes and slits may be thinly formed in advance in the frame portion so as to be easily hollowed out, and only the necessary slits may be hollowed out in accordance with the design of the attached design seal.

(Embodiment 2) FIG. 11 is a sectional view of a rotating reel portion of a reel controller of a slot machine of Embodiment 2, FIG.
2 is an explanatory view of a slit disk used in the reel control device of FIG. 11, and FIG. 13 is a time chart of the reel control device of FIG. In FIG. 11, 11a is a support 11b.
The reel body made of synthetic resin reinforced by 1. is a slit disk 12 which is coaxially attached to the reel body 11a, and 13 is a symbol sticker affixed on the peripheral surface of the reel body 11a to print 20-frame symbols. The rotating reel 11 is composed of a reel body 11a, a support 11b, and a symbol seal 13. 14 is a mounting frame, 15 is a photo sensor in which a light emitting diode and a phototransistor are combined.
Box-shaped mounting bracket 15c on the mounting frame 14 with the detection unit
It is installed in. The four sets of photosensors PS1, PS2, PS3, and PS4 of the detection unit 15 are the slit disk 1
In order to detect the two slits, they are arranged in a line in the radial direction. A stepping motor 16 is attached to the attachment frame 14. Reference numeral 17 is a circular metal fitting for attaching the slit disk 12 and the rotary reel 1 to the rotary shaft 16a of the stepping motor 16.

As shown in FIG. 12, the slit disk 12
Is 20 in the circumferential direction according to the 20 symbols of the rotating reel 11.
Equally divided, a strobe hole 12a for identifying the position of the symbol frame and a slit set 12b for identifying the symbol information are provided in each frame. Here, FIG.
The first photosensor PS1 detects the strobe hole 12a, and the photosensors PS2, PS3, and PS4 detect the slit information of the slit set 12b. In the second embodiment, eight kinds of symbols are used and the slit information requires 3 bits in the binary system, so the slit set 12b is composed of three slits. The detection unit 15 for detecting the symbol appearing on the reel window is attached at a position forming an angle of 90 degrees with the symbol appearing on the reel window, as in the first embodiment. Therefore, the slit group corresponding to the design of the reel window is provided at a position delayed by 90 degrees during rotation.

Here, the rotary reel 11 is a reel, the slit disk 12 is a detection plate, the symbol sticker 13 is a symbol, the strobe hole 12a is a strobe pattern, and the detector 15
The photo sensor PS1 corresponds to the strobe detecting means.

Here, the slit disk 12 will be described in detail with reference to FIGS. Also in Example 2,
It will be described by the method of design control. First, the timing T21 in FIG. 13 indicates the time point when the point P21 in FIG. 12 passes through the detection unit 15. Each time the clock pulse is output at an interval of 4 msec, the stepping motor 16 advances by 1.8 degrees.

At timing T21 in FIG. 13, the photosensor PS1 detects the strobe hole 12a and outputs a strobe signal, and at the same time, the photosensors PS2, PS3, P are detected.
S4 detects the slit information E '. In this way, the reading of the slit information is completed at timing T22, which is just 4 msec after the rise of the strobe signal at timing T21, and the symbol signal e [binary code 111] corresponding to the symbol E is detected. This symbol signal is stored in the memory of the processing unit until the next symbol signal is detected. From 16 msec when the strobe signal is turned off from here, it is checked whether or not the symbol signal e is the symbol signal of the symbol (here symbol F). Since the symbol E is not a winning symbol, stop control is not performed, the strobe signal is turned off at timing T23, and one symbol is finished at timing T24 40 msec after the timing T21. The reading time of 4 msec shown here is determined by the capability of the signal processing circuit, and can be shortened if high-speed processing is possible.

At timing T24, at the same time, the detector 15
Detects the strobe signal of the next symbol F, reads the slit information F ′, outputs the symbol signal f [binary code 011] corresponding to the symbol F at timing T25, and the winning symbol is checked. Since this symbol F is a winning symbol, a winning symbol signal is output here. Thereafter, when the stop button that stops the rotating reel 11 is pressed at timing T26, a stop signal is output. At timing T27 when the strobe signal is turned off, the stop signal and the hit symbol signal are checked. Since both of them exist here, the rotating reel 11 stops smoothly at the timing T28. After that, the stop signal is turned off at timing T29.

When the stop signal is output during the absence of the strobe signal after the timing T27 of the symbol F, the clock pulse is output until the same symbol signal is output, as in the mode 2 of the first embodiment. Then, the stepping motor 16 is stopped there. The designated position control and the random control are the same as those in the first embodiment.

In the above two embodiments, the photosensor was used to detect the transmitted light from the strobe hole or slit, but a reflected light may be detected by writing a bar code instead of the strobe hole or slit. In this way, since there is no hole, the detection plate becomes structurally strong.

[0047]

According to the reel control device of the slot machine of the first aspect, by detecting the strobe pattern, it is possible to accurately stop the symbol of the rotating reel at a predetermined position of the reel window. Further, according to the reel control device of the slot machine of the second aspect, since the symbol pattern is provided in the circumferential direction, it is possible to accurately detect the symbol displayed through the reel window even during rotation, and to detect the symbol. Requires few parts. Further, the time for working the detection plate provided with the strobe pattern or the pattern pattern can be reduced, and there is no failure or reading error.

Further, according to the reel control device of the slot machine of the third aspect, since the stepping motor is used to drive the reel, the stop position can be accurately controlled. Further, according to the reel control device of the slot machine of the fourth aspect, since the clock pulse of the stepping motor is used for the reading timing, the structure of the symbol reading means is simplified.
