Description

  The present invention relates to a gaming machine and a coin sorting device that detect inserted gaming media.

Conventionally, a gaming machine such as a slot machine is provided with a coin sorting device (see, for example, Patent Document 1). The coin sorting device is provided with a plurality of sensors at positions where the inserted coins can pass, and the coin sorting device detects the coins inserted, and the coin sorting device outputs a detection result output from each sensor. Is determined to satisfy the predetermined condition, it is determined that the inserted coin is an appropriate coin.

For example, when a sensor including a light emitting unit and a light receiving unit is provided at a position where a coin can pass, light emitted from the light emitting unit is reflected on the coin, and the light reflected by the light receiving unit is received. By doing so, the coin sorting device detects the inserted coin. When the coin moves on the other sensor, each sensor outputs a detection signal. Therefore, the coin sorting device determines whether the interval between the detection signals input from each sensor is a preset time. Etc. are judged.

Thereafter, the coin sorting device determines that the inserted coin is appropriate, for example, when the interval between the detection signals is a preset time, and the interval between the detection signals is not the preset time. Is determined that the inserted coin is inappropriate.
JP-A-8-24434

However, since the above-described coin sorting apparatus determines whether or not a coin inserted by light reception or non-light reception by a sensor is appropriate, a light emitting element is inserted from the insertion slot by an unauthorized person and the light emission is performed. When the element blinks in the vicinity of each sensor at a specific timing, the game medium and its position are accurately recognized, for example, it is determined that a proper coin has been inserted even though no coin has been inserted. In some cases, it was not possible to prevent fraudulent activity that was conducted because of inability to do so.

Therefore, the present invention has been made in view of the above points, and a gaming machine capable of more accurately recognizing the position of a game medium such as a coin moving in the gaming machine and performing game control based on the recognition result, and An object is to provide a coin sorting device.

In order to solve the above problems, the present invention provides a storage means for storing coins, a guide means for guiding coins to the storage means, a signal transmission means for transmitting a signal to the coins guided by the guide means,
Signal receiving means for receiving a signal transmitted from a coin guided by the guiding means, transmission information generating means for generating information included in a signal transmitted from the signal transmitting means, information generated by the transmission information generating means, and signal receiving means And a guidance determination unit for determining whether or not the guidance unit is guiding a coin based on the signal received.

In the above invention, it has random number data generation means for generating random number data, and the transmission information generation means generates, as information, a specific bit string selected from a plurality of bit strings based on the random number data generated by the random number data generation means Then, the signal transmission means converts a specific bit string into a pulse signal and transmits it, and the guidance judgment means includes a specific bit string in the bit string obtained by converting the pulse signal received by the signal reception means. You may determine with the guidance means guiding the coin.

In the above invention, the transmission information generating unit generates information based on the random number data generated by the random number data generating unit every time the signal transmitting unit transmits a signal, and the guidance determining unit is configured to guide the coin. If it is determined that the specific bit string is included in the bit string obtained by converting the pulse signal received continuously a predetermined number of times, it is determined that the guiding means is guiding the coin, If it is determined that the guiding means is guiding the coin and the bit string obtained by converting the pulse signal continuously received a predetermined number of times does not include a specific bit string, the guiding means guides the coin. It may be determined that it is not.

In the above invention, the guide means is composed of one or a plurality of areas, and one or more guidance determination means are provided for each area, and the determination result of the one or more guidance determination means changes in a specific order. In addition, a guidance completion determination unit that determines that the guidance of the coin by the guidance unit has been completed may be provided.

In addition, the invention according to the present application is a coin sorting device for a gaming machine that sorts out appropriate coins from among inserted coins and discharges improper coins in order to solve the above problems. A coin passage portion formed so as to be able to pass by its own weight and a photo sensor for detecting coins passing through the coin passage portion are provided. The photo sensor includes a light emitting portion and a light receiving portion. The light receiving unit detects the coin passing through the passage unit by receiving and demodulating the light emitted by the light emitting unit in synchronization with the light emission of the light emitting unit. And

According to such an invention according to the present application, the light emitting unit emits light by modulating the oscillation of light, and the light receiving unit,
In synchronization with the light emission of the light emitting unit, by receiving and demodulating the light emitted by the light emitting unit,
In order to detect coins passing through the passage portion, the coin sorting device may have a structure that can eliminate a fraudster who tries to force a coin to be recognized by inserting a light emitting element from an insertion slot. is there. Conventionally, the coin sorting device detects the inserted coin only by light reception or non-light reception by the light receiving unit, so when a light emitting unit different from the light emitting unit arranged in the coin passage unit is inserted from the outside , It may be determined that an appropriate coin has been inserted. However, in the present invention, the coin sorting device does not determine that an appropriate coin has been inserted unless the light receiving unit receives light from the oscillation unit and a signal corresponding to the received light is not demodulated. In some cases, it is possible to have a structure that can more accurately exclude fraudsters than the device of FIG.

In the above-described invention, when the light receiving unit receives light from the light emitting unit, if the light receiving unit does not synchronize with the light emission of the light emitting unit, a coin determining unit that determines that the coin passing state is abnormal is provided. Even if the light emitting part inserted from the slot by the fraudulent person emits light in the vicinity of the light receiving part provided in the coin passage part, the light emission timing of the light emitting part provided in the coin passage part is Since they are different, the light receiving unit is not synchronized with the light emission of the inserted light emitting unit. The coin determination unit detects that the light receiving unit does not synchronize with the light emission of the light emitting unit, and determines that the current state is abnormal, so that the coin sorting device and the gaming machine emit light inserted by the fraudster. In some cases, the part can be accurately determined.

  The present invention also provides an inspection signal having a frequency different from a frequency of a signal present in the coin passage portion in a coin detection device provided in a device including a coin passage portion through which a coin can be inserted and through which the inserted coin passes. The same as the frequency of the inspection signal among the signals received by the receiving means, and the receiving means for receiving the inspection signal reflected by the coin when the coin passes through the coin passage section. Determination means for determining that the coin has passed through the coin passage only when the amplitude of the portion having the frequency is equal to or greater than a predetermined reference value.

  Therefore, the present invention can detect the passage of coins with higher accuracy than the conventional technique in which the passage of coins is detected only by the presence or absence of reception of a signal by the receiving means. In addition, since the frequency of the inspection signal is different from the frequency of the signal (for example, visible light) existing in the coin passage portion, the present invention prevents the inspection signal and the signal present in the coin passage portion from being confused. be able to.

  In addition, since the present invention is provided in the gaming machine, it can be detected with higher accuracy than in the past that the coin inserted into the gaming machine has passed through the coin passage portion.

The photosensor includes a light emitting unit and a light receiving unit, and a plurality of photosensors are arranged along the coin passing direction. An interval between a timing demodulated by one photosensor and a timing demodulated by another photosensor is set. If it is within a preset reference time, a coin detecting means for detecting coins passing through the passage portion may be provided.

The photosensor includes a light emitting unit and a light receiving unit, and a plurality of photosensors are arranged along the coin passing direction. The coin determination unit is demodulated by one photosensor and another photosensor. If the interval from the timing is not within a preset reference time, it may be determined that the state is abnormal.

The light emitting unit emits a light emission pattern including transmission data by modulating the oscillation of light, and the light receiving unit synchronizes with the light emission of the light emitting unit, and each time the light emission pattern is emitted from the light emitting unit, the light emitting unit emits light. A counting unit that counts the number of times whether the received data included in the received light emission pattern and the transmission data included in the light emission pattern emitted from the light emitting unit at the timing of synchronization coincide (demodulate successfully); The coin detecting unit is provided with a coin that passes through the passage unit when the number of matches counted by the counting unit first reaches the first reference number and then the number of mismatches reaches the second reference number. May be detected. The first reference number may be larger than the second reference number.

The light emitting unit stops emitting light at a predetermined timing, and the coin detecting unit is in an abnormal state when the light receiving state of the light receiving unit changes when light emission by the light emitting unit is not performed. May be determined. The light emitting unit stops generating light at every predetermined timing, and the counting unit counts the number of times the light receiving state of the light receiving unit has changed at each predetermined timing when the light emitting unit is not emitting light. The coin detection unit may determine that the state is abnormal when the number of times counted by the counting unit reaches the third reference number.

According to the present invention, it is possible to more accurately recognize the position of a game medium such as a coin moving in the gaming machine, and to perform game control based on the recognition result.

[First Embodiment]
(Configuration of coin sorting device)
FIG. 1 is a view showing an appearance of the slot machine 1 in the present embodiment. As shown in FIG. 1, three panel display windows are formed on the front surface of the cabinet forming the entire slot machine 1. The reels 5L, 5C, and 5R forming the reel unit are visually recognized through these panel display windows. The three panel display windows have three pay lines in the horizontal direction and two pay lines in the diagonal direction, and a game inserted from the coin insertion slot 2 provided on the front side of the slot machine 1. The number of pay lines to be activated is determined according to the number of media (here, coins). Then, when the player inserts a coin into the coin insertion slot 2 and operates the start lever 6, each reel 5L, 5C, 5R starts to rotate. And
When the player presses stop buttons 7L, 7C, and 7R provided corresponding to the reels 5L, 5C, and 5R, the rotation of the reels 5L, 5C, and 5R is stopped. The winning mode is determined by the combination of the symbols of the reels 5L, 5C, and 5R visually recognized through the panel display windows when the rotation is stopped, and the number of coins corresponding to the winning mode is paid out when winning. Further, when a coin is jammed, the coin coin is paid out by pressing a coin return button 3 provided in the coin insertion slot 2.

The coin sorting device 10 according to the present embodiment is guide means for guiding coins inserted from the coin insertion slot 2 to the hopper 152 by its own weight, and is disposed inside the slot machine 1. Coins inserted into the coin insertion slot 2 of the slot machine 1 enter the coin passage 14 from the entrance 31 shown in FIG. 2 and move toward the exit 32.

2 and 3 are a front view and a rear view of the coin sorting device 10. FIG. 4 is a diagram illustrating a state where the pressing plate 12 is separated from the substrate 11. FIG. 5 is a perspective view showing the push plate 12.

6 is a cross-sectional view taken along the line VV of FIG. 2 showing the opening / closing mechanism of the push plate 12.

As shown in FIG. 2, the coin sorting device 10 has a push plate 1 on one surface of a substantially rectangular substrate 11.
2 and a coin passage 14 formed by the guide member 13. As shown in FIG. 4, the coin passage 14 includes a vertical path 14 a and an inclined path 14 b from the inlet 31 to the outlet 32.
Consists of.

Coins inserted from the coin insertion slot 2 are selected according to the outer diameter while moving through the coin passage 14, and an appropriate coin (hereinafter, simply referred to as “appropriate coin”) is stored in the ramp 1.
4b is discharged from the outlet 32. Such an appropriate coin is detected by two photosensors 26 and 27, which will be described later, and this detection signal is input to a control circuit (not shown) of the slot machine, whereby a counter (not shown) inside the slot machine. Is counted. When a non-magnetic coin is used as a proper coin, the coin sorting device 10
Detects unauthorized use of magnetic coins as will be described later.

As shown in FIG. 4, the pressing plate 12 is rotatably mounted around a shaft 22 that can be attached to and detached from bearings 28 and 29 of the substrate 11. It is energized to touch. Further, as shown in FIG. 5, when the pressing plate 12 is mounted on the substrate 11, an opening 12 a corresponding to the inclined path 14 b of the coin path 14 is formed.

A first protrusion member 15 that discharges an improper coin having a smaller diameter than the appropriate coin (hereinafter simply referred to as “inappropriate coin”) to the passage surface 20 of the coin passage 14 shown in FIG. 2. A pair of upper and lower projecting ends 16, 17 formed as tip portions of the projecting portion project. The first protrusion member 15 is provided on a surface 30 (see FIG. 3) opposite to the passage surface 20 formed on one surface of the substrate 11, and one end portion thereof is formed in a bifurcated manner. The tip part is a pair of protruding ends 16.
17. The protruding ends 16 and 17 according to the present embodiment are provided with arcuate slopes 16a and 17a that are inclined in the coin moving direction in order to facilitate the discharge of inappropriate coins.

As shown in FIG. 7, the first projecting member 15 is rotatable about a longitudinal axis 61 supported by bearings 67, 68 provided on the substrate 11, and usually the first projecting member 15 by a spring 62.
A pair of upper and lower projecting ends 16, 17 of the bifurcated tip end portion is urged so as to project from the passage surface 20. As shown in FIG. 8, the upper protruding end 16 protrudes from the passage surface 20 rather than the lower protruding end 17, thereby facilitating the coin discharge.

A coin having a smaller diameter than the appropriate coin is discharged together with the shapes of the protruding ends 16 and 17 of the first projecting member 15 by the biasing force of the spring 62 as will be described later. The spring 62 has an elastic force such that when the appropriate coin passes through the coin passage 14, the protruding ends 16, 17 are pushed and pulled by the coin.

Here, a mechanism for discharging coins when coins or foreign objects are jammed in the coin passage 14 in spite of a regular game in the present embodiment will be described.

  This mechanism operates in conjunction with the coin return button 3 of the slot machine 1 shown in FIG.

For this reason, as shown in FIGS. 3 and 6, the lower end of the coin return button 3 is arranged in the vicinity of a substantially triangular rotation or turning member 81, and the coin return button 3 itself is provided by a spring or the like (not shown). Always energized upward.

When the operator presses the coin return button 3, as shown in FIG.
And pivoting about a horizontal shaft 82 attached to a bearing 86 formed integrally with the pivoting member 81.
One end of the plate moves so as to push up the push plate 12. Therefore, the push plate 12 rotates about the shaft 22 and the gap between the push plate 12 and the passage surface 20 of the substrate 11 is widened.

8 to 10 are diagrams showing a means for detecting the passage of a proper coin. When the coin passes, the projecting ends 16 and 17 of the first projecting member 15 are pushed by the coin and rotate around the vertical axis 61. In this case, the rear end portion 66 of the first projecting member 15 is the first detector. Is a transmissive photosensor 6
3 (see FIG. 3) crosses the optical path between the light emitting unit 64 and the light receiving unit 65 (see FIG. 10), so that the transmissive photosensor 63 outputs a detection signal. This detection signal is sent to a control circuit (not shown) of the slot machine 1 so that the coin sorting device 10 detects that a coin has passed through the coin passage 14.

When a coin clogging occurs in the coin passage 14 or when an illegal operation is performed, the time during which the protruding ends 16 and 17 of the first projecting member 15 are pushed becomes longer, and the time from the rising edge to the falling edge of the detection signal is predetermined. Since it becomes longer than the time, the coin sorting device 10 detects an abnormality.

Further, when the proper coin is a non-magnetic substance, when a magnetic coin that becomes an inappropriate coin is inserted, a magnet 19 disposed in the vicinity of the projecting ends 16 and 17 of the passage surface 20 as shown in FIG. As a result, the magnetic coin is captured, and the projecting ends 16 and 17 are pulled from the passage surface 20. As a result, the length of the detection signal changes in the same manner as described above, and such an improper coin is detected.

The coin receiving mechanism 40 is arranged on the surface 30 side (see FIG. 3) of the substrate 11. As shown in FIG. 3, the coin receiving mechanism 40 is attracted by the excitation of the solenoid 41 and the columnar solenoid 41 provided on the surface 30 opposite to the passage surface 20 of the substrate 11, and is integrated with the substrate 11. A rotating member 43 that is rotated about a supporting member 42 formed on the supporting member 42, and the rotating member 4
3 is sucked, its one end 52 is pushed by its one end 44, and it rotates about the shaft 55 attached to the bearings 58 and 59 formed integrally with the substrate 11, and the projection 53 (FIG. 2). When the movable guide plate 51 rotated so as to be pulled in from the passage surface 20 and the rotation member 43 are not attracted by the solenoid 41, the contact with the other end 45 of the rotation member 43 is brought into contact with the passage surface 20. The projecting portion 72 (see FIG. 2) that has been pushed to project is rotated around a shaft 74 supported by bearings 78 and 79 formed integrally with the substrate 11 due to the weight of the other end 73. And a second projecting member 71 that can sink from the passage surface 20.

The above-mentioned movable guide plate 51 can change the interval of the guide grooves 80 between the coin accepting state (see FIG. 11) and the coin not accepting state (see FIG. 12) by the control circuit. The coin accepting state is a state in which the movable guide plate 51 is located at a position where the interval in the coin thickness direction in the coin passage 14 is slightly larger than the thickness of the appropriate coin. The coin unacceptable state is a state in which the movable guide plate 51 is located at a position where the interval in the coin thickness direction of the coin passage 14 is larger than the appropriate coin thickness. Here, the reason that the coin acceptance disabled state is provided is that the inserted coin is not sent to the inside of the gaming machine when the game preparation such as the slot machine is not completed or when the gaming machine side is not in the operating state. This is to return it.

FIG. 11 is a view showing a coin acceptable state of the coin accepting mechanism 40. In this case, the solenoid 41 is excited. The rotating member 43 is attracted by the solenoid 41, and the other end 45 of the rotating member 43 does not press the second projecting member 71. Therefore, the second protruding member 7
1 rotates by the weight of the other end 73 around a shaft 74 attached to bearings 78, 79 formed on the substrate 11, and the protruding end 72 is submerged from the passage surface 20.

Further, the interval between the passage surface 20 and the guide end 54 of the movable guide plate 51 is narrowed to the minimum interval through which an appropriate coin can pass (in this case, a guide groove 80 is formed). The protrusion 53 is also in a state of being submerged from the passage surface 20. In this state, when a proper coin is inserted as shown in FIG. 2, the proper coin is inserted into the projecting ends 16 1, 1 of the first projecting member 15.
Passing through the ramp 14b while pushing 7, it moves from the outlet 32 to an internal mechanism such as a gaming machine.

In this embodiment, two photo sensors 26 and 27 as second detectors are arranged in the vicinity of the outlet 32 of the passage surface 20 so as to be close to each other in the coin moving direction. In this case, the first photo sensor 26 is in a position where the coin passes earlier than the second photo sensor 27. That is, the first photosensor 26 is provided on the inlet side (upstream side) of the second photosensor 27.

The reason why the second detector is provided is that the number of coins passing through the coin sorting device 10 is counted as an accurate number, for some reason (including coin clogging and unauthorized operation).
This is because when the coin performs an abnormal operation, the abnormal operation is accurately detected. For example, when the following predetermined condition is satisfied, an abnormal signal is output to a control circuit such as a gaming machine.

Specifically, the predetermined condition is 1. 1. When the photo sensor 27 is turned on before the photo sensor 26 is turned on, 2. When the photo sensor 27 does not turn on after a predetermined time (for example, 100 ms) after the photo sensor 26 is turned on; 3. When the photosensor 26 does not turn off after a predetermined time (for example, 100 ms) after the photosensor 27 is turned on;
For example, after the photo sensor 26 is turned off, the photo sensor 27 is not turned off after a predetermined time (for example, 100 ms) has elapsed.

Further, when a coin having a smaller diameter than the appropriate coin is inserted in the above-described coin accepting state, the upper end of the coin having the smaller diameter is not caught in the guide groove 80 (see FIGS. 11 and 12). The first projecting member 15 is cut into a shape and abuts against the projecting ends 16 and 17 and is ejected by being urged in the ejecting direction (front side in FIG. 2, the same applies hereinafter).

On the other hand, as shown in FIG. 12, when the coin accepting mechanism 40 is in a state where coins cannot be accepted,
All the inserted coins are discharged to the left side of FIG. 12 by the protrusion 53 of the movable guide plate 51 protruding into the coin passage 14 and the protrusion end 72 of the second protrusion member 71, and the coin return port of the slot machine 1 of FIG. Return to 4. The protruding portion 53 of the movable guide plate 51 is provided so as to protrude vertically from the passage surface 20 so that the coin is never allowed to pass to the outlet 32 side. The protruding end 72 of the second projecting member 71 includes a slope 72a that is obliquely cut into an arc shape like the protruding ends 16 and 17 in order to bias the coin in the discharging direction.

(Operation of coin sorting device)
The operation of the coin sorting apparatus 10 according to the above-described embodiment is as follows. First, as shown in FIG. 2, the inserted coin enters from the entrance 31 and reaches the exit 32 through the ramp 33.

In the above-described coin accepting state, the movable guide plate 51 is positioned at the guide end 5 as shown in FIG.
4 and the passage surface 20, a guide groove 80 is formed, and the protruding end 72 of the second protrusion member 71 and the protrusion 53 of the movable guide plate 51 are in a state of being submerged from the passage surface 20. Among the coins entered from the entrance 31, the coin having an outer diameter smaller than that of the appropriate coin is urged by the spring 62 and is thereby passed through the passage surface 20.
It is discharged from the coin passage 14 by the protruding ends 16, 17 of the first protruding member 15 protruding from the coin passage 14.

When a coin having an appropriate outer diameter enters, the end of the coin is constrained in the guide groove 80, so that the projecting ends 16 and 17 of the first projecting member 15 are inserted into the passage surface by the coin as shown in FIG. 20, the rear end portion 66 of the first projecting member 15 cuts the optical axis of the transmissive photosensor 63 as the first detector. Therefore, a detection signal is output to a control circuit (not shown) of the slot machine to detect that the coin has passed.

The movable guide plate 51 has a coin accepting state (see FIG. 11) and a coin not accepting state (FIG. 1).
2), the guide groove 80 is formed as described above, and the projecting end 72 of the second projecting member and the other end 53 of the movable guide plate 51 pass through each other. It is in a state where it is submerged from the road surface 20. In this case, the proper coin can move to the exit 32 of the coin passage 14.

On the other hand, when the movable guide plate 51 is in a state where coins cannot be received (see FIG. 12), the movable guide plate 51 does not guide the coin at a larger interval than the case of FIG.
It encourages coins to be discharged. Further, since the projecting end 72 of the second projecting member 71 and the projecting portion 53 of the movable guide plate 51 are in a state of projecting from the passage surface 20, coins can be reliably discharged.

As described above, the proper coins inserted in the coin accepting state pass through the coin passage 14 and move from the exit 32 into the slot machine. In this case, the passage surface 2 is used as the second detector.
The passage of coins is detected by the two photosensors 26 and 27 provided in 0. When this detection signal is input to a control circuit (not shown) of the slot machine and the above-described coin is not abnormal, the number of appropriate coins passing through the coin sorting device 10 is reliably detected.

The protruding ends 16, 17, 72 of the first projecting member 15 and the second projecting member 71 are arc-shaped inclined surfaces 16 a, 17 a, 7 inclined in the coin moving direction in order to make it easier to discharge inappropriate coins.
It is formed in a shape with 2a, and in combination with the urging force of the first projecting member 15 and the second projecting member 71, the coin is expelled.

The pressing plate 12 is normally pressed against the substrate 11 by a spring 24. When a coin is jammed and the player presses the coin return button 3 with his / her finger, the turning member 81 rotates about the horizontal axis 82 so that one end of the turning member 81 pushes up the push plate 12. It moves to. Therefore, since the push plate 12 rotates about the shaft 22 and the interval (interval in the coin thickness direction) with the passage surface 20 of the substrate 11 is greatly opened, the jammed coin is discharged in the discharge direction (right side in FIG. 6). The

When a non-magnetic material is used as an appropriate coin, the passage surface 2 in the vicinity of the first projecting member 15
By arranging the magnet 19 at 0, improper coins of the magnetic material are captured by the magnetic force of the magnet 19. Thereby, since the time of the detection signal from the transmissive photosensor 63 by the first protrusion member 15 changes, the coin sorting device 10 may be able to detect an improper coin.

As described above, according to the present invention, since the coin passage is formed so as to be able to pass by the weight of the coin, the operation time can be shortened without reducing the passing speed of the coin as in the prior art. In some cases, the sorting device 10 can have a structure capable of preventing coins from being swallowed. Further, a coin passage 14 is formed from the substrate 11, the push plate 12, and the guide member 13, and mechanical means such as a movable guide plate and a first projecting member perform coin selection,
The coin sorting device 10 may have a structure that can be manufactured at a lower cost than a device using electrical means such as a conventional magnetic sensor. Further, when the second projecting member is additionally provided, proper coins are reliably counted, and coins that have not been ejected due to a malfunction of the first projecting member are also reliably ejected.

Further, when the first detector for detecting the movement of the tip end portion of the first protrusion member protruding from the coin passage 14 is provided, the coin sorting device 10 detects the detection signal output by the detector. An abnormal state may be detected from the change. Thus, for example, there may be a case where an act of playing illegally by inserting a plate-like tool called a cell into the coin passage may be prevented.

In addition, when a plurality of detectors are sequentially arranged near the exit of the coin passage 14 as the second detector, abnormal operation can be detected by the order of ON / OFF of each detector and time change.
In some cases, the coin sorting device 10 can have a structure that can prevent fraud using a thread-hanging coin or the like.

Furthermore, when a non-magnetic material is used as a proper coin, a magnet is arranged near the first detector in the coin path, so that a magnetic coin that becomes an inappropriate coin is attracted to the magnet and stopped. Or, since the moving speed of the coin changes, the coin sorting device 10 may be able to detect an improper coin due to a change in the output signal from the first detector.

(Example of change)
The present invention is not limited to the above embodiment, and the following modifications can be added. Although the transmissive photosensor 26 and the photosensor 27 are used in the above-described embodiment, the light modulation photosensor 26 and the photosensor 27 may be used instead.

b. The light emitting unit 26 a and the light receiving unit 26 b are disposed in the vicinity of the passage surface 20.

As shown in FIG. 13A, when the coin does not pass over the light emitting unit 26a and the light receiving unit 26b, the light L emitted from the light emitting unit 26a does not travel to the light receiving unit 26b, and is predetermined. Proceed forward with a tilt angle of. On the other hand, as shown in FIG.
When the light passes through the light receiving unit 26b, the light L emitted from the light emitting unit 26a is reflected by the coin and received by the light receiving unit 26b.

FIG. 14 is a diagram illustrating an electrical connection relationship between the photosensor 26 and the photosensor 27. As shown in FIG. 14, the photo sensor 26 and the photo sensor 27 include a light emitting unit 26a and a light receiving unit 26b. The light emitting unit 26a includes a first light emitting element 261a and a signal generating circuit 262a.

  The signal generation circuit 262a generates a test signal belonging to a band of 0.72 to 1.3 micrometers and a predetermined modulation signal, and synthesizes them (that is, by modulating the test signal). ) To generate a light emission pattern. The signal generation circuit 262a is connected to the first light emitting element 261a and the demodulation circuit 263b. The inspection signal is infrared light having a wavelength of 0.72 to 1.3 micrometers, and a signal existing in the coin passage 14, for example, visible light having a wavelength of 0.4 to 0.7 micrometers. Belongs to a different band. In other words, the inspection signal has a frequency different from the frequency of the signal present in the coin path 14.

The first light emitting element 261a described above blinks at a frequency corresponding to the light emission pattern based on the light emission pattern input from the signal generation circuit 262a. In order for a light receiving unit 26b, which will be described later, to synchronize the timing of light emission in the first light emitting element 261a and the timing of light reception in the first light emitting element 261a, the signal generating circuit 262a has the same wavelength and the same phase synchronization signal as the light emitting pattern. Is also output to the demodulation circuit 263b.

The light receiving unit 26b includes a first light receiving element 261b, an amplifier circuit 262b, and a demodulation circuit 263b. The amplifier circuit 262b amplifies a light reception signal corresponding to the light received by the first light receiving element 261b, and is connected to the first light receiving element 261b and the demodulation circuit 263b. The light reception signal includes a signal existing in the coin passage 14, for example, visible light, in addition to the light emission pattern.

The demodulating circuit 263b receives the light reception signal from the amplifying circuit 262b and receives the signal generating circuit 262.
When a synchronization signal is input from a, the first light emitting element 261 corresponding to the frequency of the synchronization signal
The received light signal is sampled at a timing that matches the blinking of a. The demodulation circuit 263b removes a portion (specifically, an amplified modulation signal) corresponding to the modulation signal from the light reception signal. That is, the demodulation circuit 263b demodulates the received light signal. The demodulation circuit 263b is connected to a signal generation circuit 262a, an amplification circuit 262b, and a control circuit (not shown).

  The demodulation circuit 263b attenuates a portion of the demodulated light reception signal having a frequency different from the frequency of the inspection signal, for example, visible light. Thereby, the demodulation circuit 263b can detect the inspection signal incident on the first light receiving element 261b. Specifically, the demodulation circuit 263b sends the inspection signal to the first light receiving element 261b when the amplitude of the attenuated light reception signal having a portion having the same frequency as the inspection signal is smaller than a predetermined reference value. That is, it is determined that infrared rays are not incident, and a signal indicating that the coin has not passed through the coin passage 14 is output to the control circuit (see FIG. 13A). On the other hand, the demodulating circuit 263b receives the infrared ray on the first light receiving element 261b when the amplitude of a portion having the same frequency as the frequency of the inspection signal in the attenuated light receiving signal is equal to or greater than a predetermined reference value. A signal indicating that the coin has passed through the coin passage 14 is output to the control circuit (see FIG. 13B).

That is, the light emitting unit 26a emits light by modulating light oscillation, and the light receiving unit 26b is configured to emit light.
The photo sensor 26 detects whether or not a coin has passed through the coin passage 14 by receiving and demodulating the light emitted by the light emitting unit 24a in synchronization with the light emission of the coin.

According to this modified example, the light emitting unit 26a modulates the light oscillation to emit light, and the light receiving unit 26
b detects the coin passing through the coin path 14 by receiving and demodulating the light emitted by the light emitting unit 26a in synchronization with the light emission of the light emitting unit 26a.
0 (or slot machine 1) has a structure that can eliminate a fraudulent person who inserts a light emitting element from the coin insertion slot 2 and forcibly recognizes as if a coin exists. There is. Conventionally, the coin sorting device detects the inserted coin only by light reception or non-light reception by the light receiving unit, so when a light emitting unit different from the light emitting unit arranged in the coin passage 14 is inserted from the outside. , It may be determined that an appropriate coin has been inserted. However, in the present invention, the coin sorting device 10 does not determine that an appropriate coin has been inserted unless the light receiving unit 26b receives light from the light emitting unit 26a and a signal corresponding to the received light is not demodulated. For this reason, there may be a case where it is possible to have a structure that can more accurately exclude fraudsters than conventional coin sorting devices.

  In addition, in this modification, since it is determined that the coin has passed through the coin path 14 only when the amplitude of the portion having the same frequency as the frequency of the inspection signal in the received light signal is equal to or greater than a predetermined reference value, Compared to the conventional technique in which the passage of coins is detected only by the presence or absence of signal reception, the passage of coins can be detected with higher accuracy. For example, even if a light emitting unit (hereinafter referred to as “external light emitting unit”) different from the light emitting unit disposed in the coin passage 14 is inserted from the outside and an external signal is output from the external light emitting unit, If the frequency of the external signal is different from the frequency of the inspection signal, it is possible to prevent erroneous determination that the coin has passed through the coin path 14.

  In addition, since the frequency of the inspection signal is different from the frequency of the signal (for example, visible light) present in the coin passage portion, the present invention prevents the inspection signal and the signal present in the coin passage portion from being confused. be able to.

  Further, since the present invention is provided in the slot machine 1, it can be detected with higher accuracy than in the past that the coin inserted into the slot machine 1 has passed through the coin passage 14.

Note that a control circuit (not shown) that determines that the state is abnormal when the light receiving unit 26b receives light from the light emitting unit 26a and is not synchronized with the light emission of the light emitting unit 26a is provided. Good. Thereby, even if the light emitting part inserted from the coin insertion slot 2 by the fraudulent person emits light in the vicinity of the light receiving part 26b provided in the coin passage 14, the light emitting part provided in the coin passage 14 has the timing of the light emission. Since it is different from the light emission timing of 26a, the light receiving unit 26
b is not synchronized with the light emission of the inserted light emitting unit. Then, when the control circuit detects that the light receiving unit 26b does not synchronize with the light emission of the light emitting unit 26a and determines that the current state is abnormal, the coin sorting device 10 accurately determines the fraudster. There are cases where it is possible.

A plurality of photo sensors 26 may be provided along the coin passing direction. As a result, the coin sorting device 10 can specify the detection signal input from each photosensor 26. Therefore, the coin sorting apparatus 10 determines whether or not a predetermined condition (for example, the interval between the detection signals is a preset time) is satisfied based on the detection signals input from the photosensors 26. In some cases, it is possible to more reliably determine an appropriate coin.

It should be noted that the functions of the coin sorting apparatus 10 according to the present embodiment and the modification described above (for example, the function of sorting appropriate coins and improper coins, the functions of the photo sensor 26 and the photo sensor 27) are the coin sorting apparatus. However, the present invention is not limited to this, and the slot machine 1 may be provided.

A coin sorting device for a gaming machine that sorts out appropriate coins from inserted coins and discharges the wrong coins, and a coin passage portion (for example, a coin passage portion formed so that the coin can pass by its own weight) Substrate 11, push plate 12, guide member 13), and photosensors (for example, photosensor 26 and photosensor 27) that detect coins passing through the coin passage portion. , Light emitting unit 26a) and light receiving unit (for example, light receiving unit 2)
6b), the light emitting unit modulates the oscillation of light and emits light, and the light receiving unit synchronizes with the light emission of the light emitting unit, and receives and demodulates the light emitted by the light emitting unit, You may detect the coin which passes a channel | path part.

(Operation of gaming machine and coin sorting device)
The operations of the slot machine 1 and the coin sorting device 10 according to this embodiment described above are as follows. First, the operation performed by the main control circuit 100 in this embodiment will be described. 17 to 19 are flowcharts showing the operation of the main control circuit 100 in the present embodiment.

As shown in FIG. 17, in step 1, the main CPU 131 initializes predetermined data (such as various flags and communication data).

In step 2, the main CPU 131 controls the control RAM 133 at the end of the previous game.
The predetermined data stored in is deleted. Specifically, the main CPU 131 erases the parameters used in the previous game from the control RAM 133, writes the parameters used in the next game to the control RAM 133, and designates the start address of the sequence program for the next game. Do.

In step 3, the main CPU 131 performs coin insertion / start check processing. A specific process for the coin insertion / start check process is shown in FIG.
Will be described in detail.

  In step 4, the main CPU 131 extracts random values used for various determinations.

In step 5, the main CPU 131 performs gaming state monitoring processing. In particular,
The main CPU 131 determines that the gaming state is the general gaming state, and if the winning combination is RB in the previous game and the winning combination in the previous game is not RB, the main CPU 131 sets the RB as a carryover combination. The game state is set to the RB carryover state. On the other hand, the main CPU 131
Determines that the gaming state is the general gaming state, and if the winning combination is not RB in the previous game and the carryover combination is set, the gaming state is set to the RB carryover state and the carryover combination is set. If not, leave the gaming state in the general gaming state. In addition, the main CPU 131
If the gaming state is an RB carryover state or an RB gaming state that is not a general gaming state, the gaming state remains the current RB carryover state or the RB gaming state. Note that the RB gaming state is set in step 26 described later.

In step 6, the main CPU 131 performs a probability lottery process. Specifically, the main CPU 131 determines a winning combination based on the random number extracted in step 4 with reference to a probability lottery table (not shown) according to the gaming state.

In step 7, the main CPU 131 selects a winning combination for stopping. Specifically, the main CPU 131 refers to a stop winning combination table (not shown), and determines a winning combination for stopping according to the winning combination determined in step 6 and the gaming state. The main C
The PU 131 selects an effective line for arranging the symbol combinations corresponding to the determined winning combination for stoppage.

  In step 8, the main CPU 131 performs processing for selecting a stop table.

In step 9, the main CPU 131 sends a start command to the sub-control circuit 200.
Processing to transmit to 300 is performed. This start command includes information such as a winning combination, a winning combination for stoppage, and a game state.

In step 10, the main CPU 131 determines whether or not the shortest game time (for example, 4.1 seconds) has elapsed since the previous game was started. The main CPU 13
1 shifts to the process of step 11 when the minimum game time has elapsed, and repeats this process when the minimum game time has not elapsed.

In step 11, the main CPU 131 sets the game shortest time in the game shortest time counter. The shortest game time means the time required from the end of the previous game to the start of the current game. Subtraction of the time set in the game shortest time counter is performed in step 115 of the periodic interrupt process shown in FIG.

In step 12, the main CPU 131 sets rotation start request information for instructing to start rotation of all the reels 5L, 5C, 5R.

In step 13, the main CPU 131 sets a reel stop permission command instructing permission to stop the reels 5L, 5C, 5R.

In step 14, the main CPU 131 determines whether or not the stop buttons 7L, 7C, 7R are operated by the player. Specifically, the main CPU 131 determines whether or not the input from the reel stop signal circuit 46 is on. The main CPU 131
If the input is on, the process proceeds to step 15. If the input is off, the process is repeated.

In step 15, the main CPU 131 performs a sliding frame number determination process. Specifically, the main CPU 131 determines the number of sliding symbols based on the stop operation position and stop control position of the stop table selected in the table line selection process in step 8.

In step 16, the main CPU 131 determines that there is a stop request when any of the stop buttons 7L, 7C, and 7R is pressed, and waits until the reel rotates by the number of sliding frames determined in step 15. . Note that the process of rotating the reel is performed by a reel control process of a periodic interrupt process shown in FIG.

In step 17, the main CPU 131 sets a reel stop command for instructing to stop the rotation of the corresponding reel.

In step 18, the main CPU 131 determines whether or not all the reels 5L, 5C, 5R are stopped. The main CPU 131 proceeds to the process of step 19 when all the reels 5L, 5C, and 5R are stopped, and proceeds to the process of step 14 when all the reels 5L, 5C, and 5R are not stopped. Move.

In step 19, the main CPU 131 sets an all reels stop command indicating that all the reels 5L, 5C, 5R are stopped.

In step 20, the main CPU 131 performs a winning search. Winning search is to identify a winning combination (winning combination) based on the pattern stop mode. Specifically, the main CPU 131 specifies a winning combination based on a code number of symbols arranged along the center line 8c and a winning determination table (not shown).

In step 21, the main CPU 131 determines whether or not the winning combination is normal. The main CPU 131 proceeds to the process of step 22 when the winning combination is not normal, and proceeds to the process of step 23 when the winning combination is normal. The determination of whether or not the winning combination is normal is configured to be determined to be normal when the winning combination is included in the winning combination or when the winning combination is included in the carryover combination. For example, if the winning combination is a unit game in which a bell combination or a watermelon combination, the winning combination is determined to be normal if the winning combination is a bell combination, watermelon combination or loss. In addition, when the winning role is a bell small role and the carryover role is RB, the winning role is a bell small role,
If it is RB or lost, it is determined as normal.

In step 22, the main CPU 131 displays an illegal error. In this case, the main CPU 131 stops the game.

In step 23, the main CPU 131 sets a winning command for identifying the winning combination.

In step 24, the main CPU 131 determines whether or not the winning combination is RB.

In step 25, the main CPU 131 clears the carryover combination corresponding to the winning combination RB.

In step 26, the main CPU 131 performs credit or payout of coins according to the winning combination (for example, RB) and the gaming state. Further, when the winning combination is RB, the main CPU 131 shifts the gaming state to the RB gaming state. In addition, the main CP
U131 stores information indicating that the winning combination is replay when the winning combination is replay. Based on this information, the main CPU 131 determines whether or not to automatically insert coins when the next game starts. The main CPU 131
When the process of step 3 is performed, the information indicating that the winning combination is replay is cleared.

In step 27, the main CPU 131 determines whether or not the gaming state is the RB gaming state. The main CPU 131 proceeds to the process of step 28 when the gaming state is the RB gaming state, and proceeds to the processing of step 2 when the gaming state is not the RB gaming state.

In step 28, the main CPU 131 checks the number of RB games. In this process, for example, the number of games in the RB gaming state and the number of winnings in the RB gaming state are checked.

In step 29, the main CPU 131 determines whether or not the RB gaming state has ended. Specifically, after detecting that “BAR-BAR-BAR” is stopped and displayed along the active line, after the RB wins, the main CPU 131
It is determined whether or not the number of JAC game winnings in the gaming state is 8 or the number of games in the RB gaming state is 12. The main CPU 131 proceeds to the process of step 30 when the RB gaming state is finished, and proceeds to the process of step 2 when the RB gaming state is not finished.

In step 30, the main CPU 131 performs RB end processing. Specifically, the main CPU 131 performs processing for returning the gaming state to the general gaming state after the RB gaming state is ended.

FIG. 20 shows a periodic interrupt process that interrupts the main process of the slot machine 1 (the process of FIGS. 17 to 19 described above) at a predetermined interval (here, 1.1725 ms). As shown in FIG. 20, in step 101, the main CPU 131 saves the data stored in the register.

  In step 102, the main CPU 131 checks each input port.

  In step 103, the main CPU 131 adds 1 to the value of the interrupt counter.

This interrupt counter is a work area of the control RAM 133 for counting the number of times that the periodic interrupt processing shown in FIG. 20 has been performed.

In step 104, the main CPU 131 confirms whether or not the value of the interrupt counter is an even number. The main CPU 131 proceeds to the process of step 111 when the value of the interrupt counter is an even number, and proceeds to the process of step 105 when the value of the interrupt counter is not an even number. Here, only when NO is determined in step 104, step 106 is performed.
, 108 and 110, the reel control processing is performed every 2.235 ms instead of every 1.1725 ms.

In step 105, the main CPU 131 sets information regarding the right reel 5 </ b> R in reel identification information indicating information regarding the reels 5 </ b> L, 5 </ b> C, 5 </ b> R provided in the control RAM 133.

In step 106, the main CPU 131 performs a reel stop process for the right reel 5R. Specifically, first, when the rotation start request information is set in step 12 of FIG. 18 described above, the main CPU 131 starts the rotation of the right reel 5R and moves it to the right until a constant rotation speed is reached. The rotation of the reel 5R is gradually accelerated. And main C
When the rotational speed of the right reel 5R becomes constant and the stop button 7R is pressed, the PU 131 determines that there is a stop request, and rotates and stops the reel by the number of sliding frames determined in step 20.

In step 107, the main CPU 131 sets information regarding the middle reel 5C in the reel identification information.

In step 108, the main CPU 131 performs a reel stop process for the middle reel 5C. Since this process is the same as step 106 described above, detailed description thereof is omitted.

In step 109, the main CPU 131 sets information regarding the left reel 5L in the reel identification information.

In step 110, the main CPU 131 performs a reel stop process for the left reel 5L. Since this process is the same as step 106 described above, detailed description thereof is omitted.

In step 111, the main CPU 131 performs control to display numerical values and the like on a display unit (not shown) composed of 7-segment LEDs.

In step 112, when a coin is inserted, the main CPU 131 controls a coin selector that distributes a normal coin and an abnormal coin.

In step 113, the main CPU 131 performs control to light a hit display lamp (not shown) provided on the front surface of the cabinet.

In step 114, the main CPU 131 sends various commands to the sub-control circuit 200.
To 300.

In step 115, the main CPU 131 performs a process of subtracting a predetermined number from the values of various counters. For example, the main CPU 131 performs a process of subtracting a predetermined number from the value of the game shortest time counter set in step 11.

  In step 116, the main CPU 131 restores the saved register.

FIG. 21 is a diagram showing the coin insertion / start check process in step 3 described above. As shown in FIG. 21, in step 201, the main CPU 131 confirms whether or not the transmissive photosensor 63 is continuously turned on for a specific time (here, 2 seconds). The main CPU 131 proceeds to the process of step 202 when the transmissive photosensor 63 is continuously turned on for 2 seconds, and when the transmissive photosensor 63 is not continuously turned on for 2 seconds. Goes to step 204.

Here, as described in the first embodiment, the transmissive photosensor 63 is provided on the back side of the protruding ends 16 and 17 shown in FIG. In other words, it is provided on the inlet side and upstream side. For this reason, when a coin is inserted into the coin insertion slot 2, the inserted coin passes through the protruding ends 16 and 17 provided on the entrance 31 side of the coin sorting device 10, and then the coin sorting device 10. It passes through the photo sensor 26 and the photo sensor 27 provided on the outlet 32 side.

The transmissive photosensor 63 is always on when the coin does not pass through the protruding ends 16 and 17, in other words, when the protruding ends 16 and 17 protrude into the coin passing portion, and the coin is protruded at the protruding end. When passing over 16 and 17, it is off. Therefore, when the transmissive photosensor 63 is continuously turned on for 2 seconds, that is, when YES is determined in step 201, the coin is jammed near the transmissive photosensor 63.

In step 202, the main CPU 131 sets data for displaying a coin passage check error.

In step 203, the main CPU 131 outputs a command to the image control circuit 200 to instruct the liquid crystal display device 400 to display information related to coin jamming based on the set coin passage check error display data. It is determined that the state of the slot machine 1 is an error state, and the operation of the slot machine 1 is interrupted. Note that the store clerk at the amusement hall opens the door of the slot machine 1, takes out or flushes the coins that are jammed, and turns on the power of the slot machine 1 again to release the error state of the slot machine 1.

In step 204, the main CPU 131 sets an initial state to coin passing state information which is information relating to a state opposite to the detection result of the photosensor 26 or the photosensor 27. The coin passing state information is information relating to a first selector signal and a second selector signal from a first selector port 94a and a second selector port 94b, which will be described later, and this information H is stored as an initial state. Further, the main CPU 131 sets 0 as an initial value in the coin passage timer.

In step 205, the main CPU 131 confirms whether or not the coin passing state information has changed. Further, the main CPU 131 proceeds to the process of step 206 when the coin passing state information has changed, and when the coin passing state information has not changed, the main CPU 131 proceeds to step 21.
The process proceeds to 0.

  In step 206, the main CPU 131 updates the coin passing state information.

Here, the main CPU 131 confirms whether or not there is each selector signal from the first selector port 94a and the second selector port 94b, which are output terminals of the coin sorting device 10, and thereby the photosensor 26 and the photosensor 27. The coin passing state information, which is information relating to a state opposite to the detection result (a state in which the light receiving state is indicated by negative logic), is updated. In particular,
When the coin has not passed through the photo sensor 26 and the photo sensor 27, the light emission pattern emitted from the photo sensor 26 and the photo sensor 27 goes straight, and the light emission pattern is directed toward the photo sensor 26 and the photo sensor 27. Since the light is not reflected, the detection results of the photo sensor 26 and the photo sensor 27 are turned off. In this case, High (hereinafter simply referred to as H) corresponding to ON, which is the opposite state to the detection results of the photosensors 26 and 27, is the first selector signal and the second selector signal as the first selector. Since the data is output from the port 94a and the second selector port 94b to the main CPU 131, the main C
The PU 131 stores the input first selector signal H and the second selector signal H in the control RAM 133 as coin passing state information.

In addition, when the coin is located within the detection range of the photo sensor 26 or the photo sensor 27, the light emission pattern emitted from the photo sensor 26 or the photo sensor 27 is reflected by the coin. The detection result of the sensor 27 is turned on. When the reception data corresponding to the received light emission pattern matches the transmission data corresponding to the light emission pattern previously emitted from the photosensor 26 or the photosensor 27,
Since the detection result of the photo sensor 26 or the photo sensor 27 is appropriate, Low (hereinafter simply referred to as L) corresponding to OFF, which is the opposite state of the detection result, is used as the first selector signal and the second selector signal. The data is output from the first selector port 94a and the second selector port 94b to the main CPU 131. The main CPU 131 stores the inputted first selector signal L and the second selector signal L as coin passing state information.

In this embodiment, it is determined whether or not the reception data corresponding to the received light emission pattern matches (or does not match) the transmission data corresponding to the light emission pattern previously emitted from the photosensor 26 or the photosensor 27. Has been performed a predetermined number of times, and is in a state opposite to the detection result of the photosensor 26 or the photosensor 27 only when the received data matches (or does not match) the transmission data in all the predetermined times H (or L) corresponding to is output from the first selector port 94a or the second selector port 94b to the main CPU 131 as the first selector signal or the second selector signal. This will be described in detail in the selector signal output processing of FIG.

22 to 26 are diagrams showing how the coin passing state information changes. FIG.
26A to 26A show how the coin passes through the photo sensor 26 and the photo sensor 27. FIGS. 22B to 26B show the first selector port according to the position of the coin. It is a figure which shows a mode that the 1st selector signal and 2nd selector signal output from 94a and the 2nd selector port 94b are memorize | stored as coin passage state information.

As shown in FIGS. 22A and 22B, the coins are the photo sensor 26 and the photo sensor 2.
If it is not within the detection range 7, the main CPU 131 keeps the coin passage state information as it is because the coin passage state information set in step 204 described above has not changed. In this case, since the coin is not located within the detection range of the photo sensor 26 and the photo sensor 27, the detection result of the photo sensor 26 and the photo sensor 27, and the coin passing state information do not change. N at 205
O will be determined.

As shown in FIGS. 23A and 23B, when the coin is located within the detection range of the photosensor 26 and outside the detection range of the photosensor 27, it corresponds to the received light emission pattern. On the condition that the reception pattern and the transmission data corresponding to the light emission pattern emitted before that coincide with each other a predetermined number of times, L corresponding to OFF, which is a state opposite to the detection result of the photosensor 26, is obtained. A first selector signal from the first selector port 94a serves as the first selector signal.
1 is output. Further, since the coin is located outside the detection range of the photosensor 27, the second selector signal is kept at H and is sent from the second selector port 94b to the main CPU1.
31 is output. When the state changes from FIGS. 22A and 22B to FIGS. 23A and 23B, that is, the signals received by the main CPU 131 as the first selector signal and the second selector signal are H, When changing from H to L, H, the main CPU 1
31 determines YES in step 205 and updates L as the first selector signal and H as the second selector signal as coin passing state information in step 206. Here, the first selector signal and the second selector signal input in the determination result in step 205 at a specific timing are H and H, respectively, and the first selector signal input in the determination process in step 205 at the timing next to the specific timing. If the first selector signal and the second selector signal are H and H, respectively, NO is determined in step 205.

As shown in FIGS. 24A and 24B, the coins are the photo sensor 26 and the photo sensor 2.
7 and when the detection result of the photosensor 27 also changes from OFF to ON, a reception pattern corresponding to the received light emission pattern and a transmission corresponding to the light emission pattern emitted before that On the condition that the data matches the predetermined number of times, L corresponding to OFF, which is the opposite state of the detection result of the photosensor 27, is output from the second selector port 94b to the main CPU 131 as the second selector signal. The Further, FIG. 23 (a) and (b) described above.
Since the coin is still positioned within the detection range of the photo sensor 26 as described in the above, the first selector signal is held at L and the main CPU 1 is switched from the first selector port 94a.
31 is output. In this case, the main CPU 131 determines in step 205 that YE
S is determined, and in step 206, the first selector signal L and the second selector signal L are updated as coin passing state information.

As shown in FIGS. 25A and 25B, the coin moves from the detection range of the photosensor 26 to the outside of the detection range, is positioned within the detection range of the photosensor 27, and the detection result of the photosensor 26 is In the case of changing from ON to OFF, the photo pattern is received on the condition that the reception pattern corresponding to the received light emission pattern and the transmission data corresponding to the previous light emission pattern do not match a predetermined number of times. H corresponding to ON, which is the state opposite to the detection result of the sensor 26, is output from the first selector port 94a to the main CPU 131 as the first selector signal.

Also, as described above with reference to FIGS. 24A and 24B, since the coin is still positioned within the detection range of the photosensor 27, the second selector signal is held at L while the second selector signal is held at L. 2 is output from the selector port 94b to the main CPU 131. In this case, the main CPU
In step 205, YES is determined in step 205, and in step 206, the first selector signal H and the second selector signal L are updated as coin passing state information.

As shown in FIGS. 26A and 26B, when the coin passes not only the photo sensor 26 but also the photo sensor 27, and the detection result of the photo sensor 27 changes from on to off,
On the condition that the reception pattern corresponding to the received light emission pattern and the transmission data corresponding to the previously emitted light emission pattern do not match a predetermined number of times, a state opposite to the detection result of the photosensor 27 H corresponding to ON is output from the second selector port 94b to the main CPU 131 as the second selector signal. Also, as described above with reference to FIGS. 25A and 25B, since the coin has already passed through the photosensor 26, the first selector signal is held at H, and the first selector port 94a. To the main CPU 131. In this case, the main CPU 131 determines YES in step 205, and in step 206, updates the first selector signal H and the second selector signal H as coin passing state information. As shown in FIG. 26 (b), the information corresponding to the first selector signal in the coin passing state information is in a specific order (here, H → L → L → H → H), and the second selector When the information corresponding to the signals is in a specific order (here, H → H → L → L → H), the main CPU 131 detects that the coin is detected by the photosensor 26 and the photosensor 27 based on the coin passage state information. Is determined to have passed.

In step 207, the main CPU 131 confirms whether or not the change in the coin passing state information is normal. As described above with reference to FIGS. 22 to 26, information corresponding to the first selector signal in the coin passing state information changes in the order of H → L → L → H → H (including some changes). The information corresponding to the second selector signal changes in the order of H → H → L → L → H (
The main CPU 131 indicates that the coin is the photo sensor 2.
6 and the photo sensor 27 are determined to pass normally.

On the other hand, when the information corresponding to the first selector signal and the second selector signal does not change in the above-described order, the main CPU 131 indicates that the coin has not normally passed through the photosensor 26 or the photosensor 27. judge. For example, the information corresponding to the first selector signal is H → L → H, and the information corresponding to the second selector signal is H → H → H at the same timing.
In this case, the coin is located within the detection range of the photo sensor 26, but the coin is then returned in the direction opposite to the coin flow direction.
It is determined that the coin has not normally passed through the photosensor 26 and the photosensor 27.

The main CPU 131 proceeds to the process of step 209 when the change of the coin passing state information is normal, and proceeds to step 208 when the change of the coin passing state information is not normal.
Move on to processing.

In step 208, the main CPU 131 sets backward error display data instructing to notify that the passage of coins is not normal, and performs error processing. As a result, the slot machine 1 notifies the fact, so that the store clerk at the amusement hall positions the coin to which the fraudster has attached the string up to the vicinity of the photosensor 26 or the photosensor 27 and pulls out the coin. May be able to quickly identify the act. When the cause of this error is specified by a game clerk and the error is released, the initial state is set as the coin passing state and 0 is set as the initial value in the coin passing timer.

In step 209, the main CPU 131 sets an initial value (here, a value corresponding to 100 ms) to the coin passage timer. The coin passing timer is the complete photo sensor 26 after the coin is located within the detection range of the photo sensor 26 or the photo sensor 27.
Alternatively, it is a work area of the control RAM 208 for counting the maximum time until it passes through the photo sensor 27. When the value of the coin passage timer is larger than 0, the above-described FIG.
In step 114 of FIG. That is, the main CPU 131 is configured to decrement every 1.1725 ms.

In step 210, the main CPU 131 determines whether the value of the coin passage timer is 0 or whether the coin has passed the detection range of the photo sensor 26 and the photo sensor 27 (that is, the state where the coin passage state information is shown in FIG. 26B). Or whether the coin passage state information is in the initial state. The main CPU 131 proceeds to the process of step 211 when any of these is satisfied, and proceeds to the process of step 205 when any of these is not satisfied.

In step 211, the main CPU 131 confirms whether or not the coin passing state has changed from the initial state. Specifically, when the coin passage state information is in the initial state, the main CPU 131 determines that both the first selector signal H and the second selector signal H are in the coin passage state information (FIG. 22B). Therefore, it is confirmed whether or not the coin passing state information has changed from H.

The main CPU 131 proceeds to the process of step 212 when the coin passing state information has changed from the initial state, and moves to the process of step 216 when the coin passing state information has not changed from the initial state.

In step 212, the main CPU 131 confirms whether or not the coin has passed through the photo sensor 26 and the photo sensor 27. The main CPU 131 proceeds to the process of step 215 when the coin passes through the photo sensor 26 and the photo sensor 27, and proceeds to step 2 when the coin does not pass through the photo sensor 26 and / or the photo sensor 27.
The process proceeds to step 13. Specifically, the main CPU 131 changes the information corresponding to the first selector signal in the order of H → L → L → H → H, and the information corresponding to the second selector signal is H → H → H at the same timing. When the order changes in the order of L → L → H, the coin is detected by the photo sensor 26.
Then, it is determined that it has passed through the photosensor 27 normally, and the process proceeds to step 215. On the other hand, when the first selector signal and the second selector signal do not change in the above-described order, the main CPU 131 determines that the coin has not normally passed through the photo sensor 26 and the photo sensor 27. Then, the process proceeds to step 213.

Here, when the coin is located within the detection range of the photosensor 26 or the photosensor 27, or the coin is removed from these positions, the coin passing state information changes. For this reason,
In step 209, every time the coin passing state information changes, the initial value is updated in the coin passing timer.

Accordingly, since the initial value is sequentially updated in the coin passage timer from when the coin is positioned within the detection range of the photosensor 26 until the coin passes the photosensor 27, the value of the coin passage timer does not become zero. . Therefore, if YES is determined in step 210, the time corresponding to the coin passing timer (100 ms in the present embodiment) has elapsed, so in step 212, the main CPU 131 indicates that the coin passing state information is as shown in FIG.
Unlike the information shown in (b), when the coin passage timer is 0, it is determined that the coin is jammed within the detection range of one or both of the photosensor 26 and the photosensor 27, Move on to processing. For example, the information corresponding to the first selector signal changes from H to L,
If the L does not change even after 100 ms, which is the time corresponding to the coin passing timer, elapses, the main CPU 131 determines that the coin is jammed by the photo sensor 26.

On the other hand, in step 212, the main CPU 131 has all the information corresponding to the first selector signal (H → L → L → H → H) and all the information corresponding to the second selector signal (H → H → L → L → H). If it exists, it is determined that the coin has passed through the photo sensor 26 and the photo sensor 27, and the process proceeds to step 215.

In step 213, the main CPU 131 issues a command for instructing that the coin is jammed by the photo sensor 26 or the photo sensor 27 to the image control circuit 200.
Since the processing of the slot machine 1 is in an error state, the slot machine 1
Interrupt the operation. It should be noted that a game shop clerk opens the door of the slot machine 1, removes or throws a coin, and cancels the error operation of the slot machine 1.
131 cancels the error state of the slot machine 1.

In step 213, the CPU 131 outputs a command instructing that the coin is jammed in the vicinity of the photo sensor 26 or the photo sensor 27. On the other hand, in step 208 described above, the CPU 131 This is different in that a command is output by the person instructing the user to notify that the coin has been returned in the direction opposite to the coin flow direction.

In step 214, the main CPU 131 determines that the error has been canceled.
Similar to step 204 described above, the initial state is set in the coin passing state information, and the coin passing timer is set to zero.

In step 215, the main CPU 131 adds 1 to the number of coins inserted, sets the initial state to the coin passing state information, and sets the coin passing timer to 0.

In step 216, the main CPU 131 confirms whether or not the number of inserted coins is three. The main CPU 131 proceeds to the process of step 217 when the inserted number of coins is 3, and proceeds to the process of step 1 when the inserted number of coins is not 3.

That is, when three coins are inserted, the operation of the start lever 6 is accepted. In the present embodiment, the slot machine 1 dedicated to so-called 3 sheets is described. When the maximum number of coins to be multiplied is changed according to the gaming state, the number of determinations used in the determination process of step 216 is determined as the gaming state. It is necessary to change according to.

In step 217, the main CPU 131 confirms whether or not the start lever 6 is operated. The main CPU 131 ends the coin insertion / start check process when the start lever 6 is operated, and repeats the process when the start lever 6 is not operated.

In step 305, the coin supervisory control CPU 90 converts the second transmission data from 1 to 126.
Update any value within the range of. For example, the coin monitoring control CPU 90 determines a value by random number lottery or the like, and stores the value determined as the second transmission data again.

Here, as shown in FIG. 30 to be described later, the first transmission data and the second transmission data are composed of 7 bits (D1 to D7 shown in FIG. 30), and 126 patterns except for all 0s and all 1s. Have a combination. The first light emission pattern (or second light emission pattern) including the first transmission data (or second transmission data) is the first light emitting element 26 in step 430 described later.
Light is emitted from 1a (or the second light emitting element 271a).

FIG. 28 is a diagram showing the initialization process in step 301 described above. As shown in FIG. 28, in step 301-1, the coin supervisory control CPU 90 performs a process for prohibiting interruption (occurrence of a periodic interrupt process shown in FIG. 29 described later).

In step 301-2, the coin supervisory control CPU 90 converts the first selector signal L and the second selector signal L to the first selector port 94 a and the second selector port 9.

In step 301-3, the coin supervisory control CPU 90 sets 0 to the first match counter and the first mismatch counter. The first coincidence counter is the first light emitting element 261a.
The first transmission data corresponding to the first light emission pattern emitted from the first reception data corresponding to the first light emission pattern emitted from the first light emitting element 261a, reflected by the coin and received by the first light receiving element 261b. This is a work area of the transmission data / reception data RAM 91 for counting the number of times data continuously matches. The first mismatch counter is the first light emitting element 2.

In step 301-4, the coin supervisory control CPU 90 sets 0 to the second match counter and the second mismatch counter. The second coincidence counter is the second light emitting element 271a.
The second transmission data corresponding to the second light emission pattern emitted from the second light transmission pattern and the second reception corresponding to the second light emission pattern emitted from the second light emitting element 271a, reflected by the coin and received by the second light receiving element 271b. This is a work area of the transmission data / reception data RAM 91 for counting the number of times data continuously matches. The second mismatch counter is the second light emitting element 2.

In step 301-5, the coin supervisory control CPU 90 sets 0 to the first light reception error counter. This first light reception error counter is the periodic number of times that the first light receiving element 261b is continuously in the light receiving state when the first light emitting element 261a is off (that is, when there is no light emission) as shown in FIG.

While the first light emission pattern and the second light emission pattern are L, when the detection result of the first light receiving element 261b or the second light receiving element 271b is on in the light receiving error detecting process in step 423 described later. Is determined as an error in the detection result of the first light receiving element 261b or the second light receiving element 271b. Thereby, the slot machine 1 may be able to immediately recognize that the light emitting element inserted from the outside is lit in the vicinity of the photosensor 26 or the photosensor 27.

In addition, as shown in FIG. 30, the first transmission data and the second transmission data selected in the periodic interrupt process shown in FIG. 29 are output in step 430, and the output time corresponds to t2. D1 to D7 between t2 and t3 are light emission patterns corresponding to the transmission data. Note that ST in FIG. 30 means a start bit of the light emission pattern, SP means a stop bit of the light emission pattern, and the first light emission pattern is continuously generated until the next periodic interruption occurs and the start of step 402. The second light emission pattern is held as H. That is, the first light emitting element 261a and the second light emitting element 271a continue to emit light.

In step 403, the coin supervisory control CPU 90 converts the second transmission data from 1 to 126.
Update within the range of. Here, since only the second transmission data is updated again in step 403, the first transmission data and the second transmission data are unlikely to have the same value. This
Since it becomes difficult for the first light emission pattern and the second light emission pattern corresponding to each transmission data to be the same, it is difficult for an unauthorized person to specify a pattern that matches the first light emission pattern and the second light emission pattern.

In step 404, the coin supervisory control CPU 90 selects the first received data RAM 91b in which the first received data is stored. Here, if the first reception data is stored in the first reception data RAM 91b, the first reception data is stored in the first interruption step 429.
The serial interface 93a of the coin supervisory control CPU 90 passes through the first light receiving element 261b after the storage permission of the reception data is made until the storage of the first reception data is prohibited in step 401 at the time of the current interruption. In this case, the 7-bit serial data received following the start bit signal is stored in the first received data RAM 91b based on the detection of the start bit signal.

In step 405, the coin supervisory control CPU 90 selects the first transmission data RAM 91a in which the first transmission data is stored in the previous periodic interruption process as a storage location of comparison data used in step 410 described later.

Here, as shown in FIG. 32 to be described later, when the current interruption time is t3, the transmission data stored in the first transmission data RAM 91a is the first transmission data at t1 which is the previous interruption time. (Comparison data). Further, as shown in FIG. 32, the reception data stored in the first reception data RAM 91b becomes the first reception data between t2 as the previous interruption and t3 as the current interruption. These first transmission data and first reception data are used in step 410 described later.

In step 406, the coin supervisory control CPU 90 selects the first coincidence counter as the coincidence counter.

In step 407, the coin supervisory control CPU 90 selects the first match counter as the mismatch counter.

In step 408, the coin supervisory control CPU 90 selects the first selector port 94a as the selector port.

In step 409, the coin supervisory control CPU 90 selects 5 as the upper limit value of the mismatch counter.

In step 410, the coin supervisory control CPU 90 performs a selector signal output process. Specific details of this selector signal output processing will be described later with reference to FIG.

Here, in step 404 to step 410, the coin monitoring control CPU 90 performs the first transmission data corresponding to the light emission pattern received by the photosensor 26 and the first transmission corresponding to the light emission pattern previously emitted from the photosensor 26. The first selector signal is sent to the first selector port 94 in accordance with the number of times of continuous matching with data (or the number of times of non-matching continuously).
Processing to output from a. Similarly, step 411 to step 4 described later.
17, the coin monitoring control CPU 90 continuously matches the second reception data corresponding to the light emission pattern received by the photosensor 27 and the second transmission data corresponding to the light emission pattern previously emitted from the photosensor 27. The second selector signal is output from the second selector port 94b according to the number of times (or the number of times of disagreement successively).

In step 411, the coin supervisory control CPU 90 selects the second received data RAM 91d in which the second received data is stored. If the second received data is stored in the second received data RAM 91d, the second received data is stored in the second interrupt step 429 at the time of the previous interrupt.
The serial interface 93b of the coin supervisory control CPU 90 passes through the second light receiving element 271b between the time when the reception of the received data is permitted and the time when the storage of the second received data is prohibited in step 401 at the current interruption. In this case, the 7-bit serial data received following the start bit signal is stored in the second received data RAM 91d based on the detection of the start bit signal.

In step 412, the coin supervisory control CPU 90 selects the second transmission data RAM 91 c that stores the second transmission data at the time of the previous interruption as a storage location of comparison data used in step 417 described later.

In step 413, the coin supervisory control CPU 90 selects the second coincidence counter as the coincidence counter.

In step 414, the coin supervisory control CPU 90 selects the second match counter as the mismatch counter.

In step 415, the coin supervisory control CPU 90 selects the second selector port 94b as the selector port.

In step 416, the coin supervisory control CPU 90 selects 7 as the upper limit value of the mismatch counter.

In step 417, the coin supervisory control CPU 90 performs selector signal output processing.

The processing from step 411 to step 417 is performed from step 404 to step 4.
Since it is the same as the processing up to 10, detailed description is omitted.

In step 418, the coin supervisory control CPU 90 identifies the I / O port 92a. When the I / O port 92a is specified, the I / O port 92a is in a state where it can accept a light emission signal from the first light receiving element 261b. In this case, the light receiving pattern is not received as a serial signal as described above, but the first light receiving element 26 is connected via the I / O port.
The light receiving state of the first light receiving element 261b at the time when the input from 1b is detected is detected. Note that the light emission signal is distinguished from the light emission pattern described above, and includes a signal from a light emitting element that is illegally inserted from the outside.

In step 419, the coin supervisory control CPU 90 selects the first light reception error counter as the error counter.

  In step 420, the coin supervisory control CPU 90 performs a light reception error detection process.

Specific details of this light reception error detection processing will be described later with reference to FIG.

In step 421, the coin supervisory control CPU 90 identifies the I / O port 92b. When the I / O port 92b is specified, the I / O port 92b is in a state where it can accept a light emission signal from the second light receiving element 271b. In this case, the light receiving pattern is not received as a serial signal as described above, but the second light receiving element 27 is connected via the I / O port.
The light receiving state of the second light receiving element 271b when the input from 1b is detected is detected.

In step 422, the coin supervisory control CPU 90 selects the second light reception error counter as the error counter.

  In step 423, the coin supervisory control CPU 90 performs a light reception error detection process.

In step 424, the coin monitoring control CPU 90 sets the first light reception error counter to 4.
Check if this is the case. Further, when the first light reception error counter is 4 or more, the coin supervisory control CPU 90 proceeds to the processing of step 426 and the first light reception error counter is 4.
If not, the process proceeds to step 425.

In step 425, the coin supervisory control CPU 90 sets the second light reception error counter to 4.
Check if this is the case. Further, when the second light reception error counter is 4 or more, the coin supervisory control CPU 90 proceeds to the process of step 426, and the second light reception error counter is 4.
If not, the process proceeds to step 428. That is, if one or both of the first light reception error counter and the second light reception error counter is equal to or greater than a specific number of times (here, 4), the process proceeds to step 426 and both of the error counters described above are performed. If it is less than the specific number of times (here, 4), the process proceeds to step 428.

In step 426, the coin supervisory control CPU 90 outputs the first selector signal L from the first selector port 94a to the main CPU 131.

In step 427, the coin supervisory control CPU 90 outputs the second selector signal L from the second selector port 94b to the main CPU 131.

Here, in step 426 and step 427, the first selector signal and the second selector signal are sent from the first selector port 94a and the second selector port 94b to the main CPU 13.
In the case of being output to 1, the main CPU 131 outputs L which is the input first selector signal.
On the condition that the second selector signal L continues for a predetermined time, it is determined that the state of the slot machine 1 is an error state, and step 208 and step 21 in FIG.
3 stops the processing of the slot machine 1. In this case, the coin sorting device outputs L level signals as the first selector signal and the second selector signal until the power of the slot machine 1 is turned off, so that the error cannot be canceled.

In step 428, the coin supervisory control CPU 90 sets the first light emission pattern corresponding to the first transmission data to H and sets the second light emission pattern corresponding to the second transmission data to H. Specifically, the coin supervisory control CPU 90 sets the first light emission pattern and the second light emission pattern to H at time t1 shown in FIG. Here, in Step 402, the first light emission pattern and the second light emission pattern are set to L, and in Step 428, the first light emission pattern and the second light emission pattern are set.
By setting the light emission pattern to H, basically no light source is illuminated by the photosensor 26 and the photosensor 27 between step 402 and step 428. However, if a light-emitting element is inserted from the outside in the vicinity of the photo sensor 26 and the photo sensor 27 and an illegal act of forcibly recognizing a coin is performed, no light source is originally present. Regardless, the detection results of the photo sensor 26 and the photo sensor 27 change. For this reason, in the light reception error detection processing of step 420 and step 423, the coin monitoring control CPU 90 determines that an unauthorized light emitting element is inserted by monitoring the detection results of the photo sensor 26 and the photo sensor 27. There are cases where it is possible.

In step 429, the coin supervisory control CPU 90 executes the first received data RAM 91b.
The storage of the first reception data and the second reception data in the second reception data RAM 91d is permitted. Specifically, the coin supervisory control CPU 90 can store the first received light data in the first received data RAM 91b via the first received light element 261b and the serial interface 93a, and the second received light element 271b and the serial interface 93b. The second received light data can be stored in the second received data RAM 91d via the. After this timing,
When the serial interfaces 93a and 93b detect the star bit signal (L level signal), the serial data following the start bit signal is stored in the first reception data RAM 91b or the second reception data RAM 91d as the first light reception data or the second light reception data. To do.

Here, in this embodiment, the processing time from step 401 to step 429 is about 80.
Since it takes μs, the first received data and the second received data are stored in the first received data RAM 91b and the first received data in step 429 from the time when about 80 μs (t2 shown in FIG. 30) has elapsed since the start of the regular interrupt process. The second received data is stored in the RAM 91d, and the stored first received data is referred to in steps 404 and 410 at the next interrupt. Similarly, the second received data is also stored in step 411 at the next interrupt. And 417.

In step 430, the coin supervisory control CPU 90 emits the first light emission pattern corresponding to the first transmission data from the first light emission element 261a, and the second light emission pattern corresponding to the second transmission data from the second light emission element 271a. Emits light. Specifically, coin monitoring control C
The PU 90 switches the switch to the positions S2 and S4, and the serial interface 93a
And the first light emitting element 261a and the connection between the serial interface 93b and the second light emitting element 271a, the first light emission pattern corresponding to the first transmission data stored in the first transmission data RAM 91a is displayed. The first light emitting element 261a emits light, and the second light emitting element 271a emits a second light emitting pattern corresponding to the second transmission data stored in the second transmission data RAM 91c. In addition, since step 430 in the present embodiment is performed when about 80 μs has elapsed since the start of the regular interruption process, the first light emission pattern and the second light emission pattern are used since about 80 μs has elapsed. Light is emitted from the first light emitting element 261a and the second light emitting element 271a until 1 ms shown in FIG. 30 elapses. As a specific example of the signal to be emitted, step 304 immediately before the periodic interrupt process of FIG. 29 is started.
If the value of the first transmission data is updated to 100 by the above process, 100 is stored in the first transmission data RAM 91a by the periodic interrupt process of FIG. Since this value is 110 0100 in binary 7 bits, the first light emitting element 261a eventually outputs an L level signal, which is a start bit signal, as shown in FIG.
Based on the value of M91a, signals such as L, L, H, L, L, H, and H are sequentially output as the D1 signal to D7 signal, and an H level signal is output as the stop bit signal. That is, the first light emitting element 261a is turned off (start bit), turned off (D1), turned off (D2), turned on (
D3), unlit (D4), unlit (D5), lit (D6), lit (D7), lit (D7).

In addition, if the value of the second transmission data is updated to 50 by the process of step 403 of the periodic interrupt process of FIG. 29, 50 is stored in the second transmission data RAM 91c by the periodic interrupt process. Is done. Since this value is 011 0010 in binary 7 bits, the second light emitting element 271a eventually outputs an L level signal as a start bit signal as shown in FIG. 30 and then the value of the second transmission data RAM 91c. Accordingly, signals such as L, H, L, L, H, H, and L are sequentially output as the D1 signal to D7 signal, and an H level signal is output as the stop bit signal. That is, the second light emitting element 271a is turned off (start bit), turned off (D1), turned on (D2), turned off (D3), turned off (D4), turned on (D5).
, Lighting (D6), extinguishing (D7), lighting (D7).

FIG. 31 is a diagram showing selector signal output processing in the above-described step 410 and step 417. In the following description, unless otherwise specified, the first transmission data and the second transmission data are set as transmission data, the first reception data and the second reception data are set as reception data, and the first match counter and the second match counter are matched. A description will be given assuming that the first mismatch counter and the second mismatch counter are counters.

As shown in FIG. 31, in step 410-1, the coin supervisory control CPU 90 checks whether or not received data is stored. As shown in FIG. 32 to be described later, specifically, when the current periodic interrupt process occurs at t3, the coin supervisory control CPU 90 performs the period from t2 to t3 when the previous periodic interrupt process occurs. It is confirmed whether or not the received data corresponding to the light emission pattern emitted in between is stored. The coin supervisory control CPU 90 proceeds to step 410-2 when the received data is stored, and proceeds to step 410-5 when the received data is not stored.

In step 410-2, the coin supervisory control CPU 90 matches the transmission data (comparison data) stored at the previous interruption (here, t1) with the reception data confirmed in step 410-1. Check if it exists. If the transmission data stored at the previous interruption matches the reception data confirmed at step 410-1, the coin supervisory control CPU 90 proceeds to step 410-3 and proceeds to the previous interruption. If the transmission data stored at the time of loading does not match the reception data confirmed in step 410-1, the process proceeds to step 410-5.

In step 410-3, the coin supervisory control CPU 90 adds 1 to the coincidence counter.

In step 410-4, the coin supervisory control CPU 90 sets 0 to the mismatch counter.

In step 410-5, the coin supervisory control CPU 90 adds 1 to the mismatch counter.

In step 410-6, the coin supervisory control CPU 90 sets 0 to the coincidence counter.

In step 410-7, the coin supervisory control CPU 90 checks whether or not the value of the coincidence counter is equal to or greater than a specific value (here, 5). The coin monitoring control CPU 90
If the value of the coincidence counter is equal to or greater than a specific value (here, 5), the process proceeds to step 410-8. If the value of the coincidence counter is not equal to or greater than the specific value (here, 5), step 410-1 is performed.
Move to 0.

In step 410-8, the coin supervisory control CPU 90 calculates 1 from the value of the coincidence counter.
Is subtracted. Thereby, since the value of the coincidence counter does not become a specific value + 1 (here, 6) or more, the coin supervisory control CPU 90 may be able to avoid burdening the storage capacity of the transmission data / reception data RAM 91. is there.

In step 410-9, the coin supervisory control CPU 90 outputs the selector signal as L to the main CPU 131.

In Step 410-10, the coin supervisory control CPU 90 checks whether or not the value of the mismatch counter is less than the upper limit value selected in Step 409 or Step 416. The coin monitoring control CPU 90 determines that the value of the mismatch counter is step 409 or step 4.
If it is less than the upper limit value selected in step 16, the selector signal output processing is terminated. If the value of the mismatch counter is not less than the upper limit value selected in step 409 or step 416, the process proceeds to step 410-11.

Here, on the condition that the value of the coincidence counter or the disagreement counter is a predetermined value, the coin supervisory control CPU 9 is switched by switching the first selector signal or the second selector signal to L or H.
0 may prevent the first selector signal or the second selector signal from being set to L or H by an external noise signal, and the main CPU 131 can more accurately determine the coin passing state. There are cases where it is possible.

In step 410-11, the coin supervisory control CPU 90 subtracts 1 from the value of the mismatch counter. Thereby, since the value of the mismatch counter does not become the upper limit value or more, the coin monitoring control CPU 90 may be able to avoid burdening the storage capacity of the transmission data / reception data RAM 91.

In step 410-12, the coin supervisory control CPU 90 outputs the selector signal as L to the main CPU 131.

Here, FIG. 32 shows the first selector signal output from the first selector port 94a, the second
The second selector signal output from the selector port 94b, the first light emitting element 261a, and the first
It is a timing chart figure showing the relation between the detection result of light receiving element 261b, and the detection result of the 2nd light emitting element 271a and the 2nd light receiving element 271b. As shown in FIG. 32, the current interrupt time is t3.
In this case, since the coin monitoring control CPU 90 matches the transmission data and the reception data stored between t1 which is the previous interruption time and t3 which is the current interruption time,
Add 1 to the value of the match counter. Then, the coin monitoring control CPU 90 checks whether or not the transmission data and the reception data stored at the previous interruption match at the next interruption, and when both coincide, 1 is again added to the value of the coincidence counter.

That is, every time the periodic interrupt process shown in FIG.
The same processing is performed a predetermined number of times (here, 5 times), and if the transmission data and the reception data stored in the previous periodic interruption processing continuously match the predetermined number of times, the coin is detected by the photosensor. 26, the first selector signal output from the first selector port 94a is set to L in step 410-9 (see the time point t4 shown in FIG. 32). The conditions for setting the second selector port output from the second selector port 94b to L are the same as described above.

On the other hand, when the current interruption time is t7, the coin supervisory control CPU 90 transmits and stores the transmission data and the reception data stored between the previous interruption time t6 and the current interruption time t7. Are not matched, 1 is added to the value of the mismatch counter. That is, every time the periodic interrupt process shown in FIG. 29 occurs, the coin monitoring control CPU 90 performs the same process a predetermined number of times, and the transmission data and the reception data stored in the previous periodic interrupt process are continuous. If the coins do not match the predetermined number of times, it is determined that the coin has passed through the photo sensor 26, and the first selector signal output from the first selector port 94a is set to H in step 410-12.
(Refer to the time point t9 shown in FIG. 32). The conditions for setting the second selector port output from the second selector port 94b to H are the same as described above.

Further, as shown in FIG. 32, the coin monitoring control CPU 90 determines that the coin located within the detection range of the photo sensor 26 on condition that the value of the first mismatch counter is the upper limit value (here, 5). Is determined to have passed through the photosensor 26. On the other hand, the coin monitoring control CPU 90 determines that the coin located within the detection range of the photosensor 27 sets the photosensor 27 on the condition that the value of the second mismatch counter is the upper limit value (here, 7). Judge that it has passed. The reason why the upper limit value of the second mismatch counter is larger than the upper limit value of the first mismatch counter is as follows.

Specifically, since the inserted coin is gradually accelerated from the entrance side to the exit side of the coin passage 14, the speed when it is located within the detection range of the photosensor 27 on the exit side is
It becomes faster than the speed when it is located within the detection range of the photo sensor 26 on the entrance side. Therefore, when the upper limit value of the first mismatch counter and the upper limit value of the second mismatch counter are both 5, the time when the first selector signal is switched from L to H (t9 shown in FIG. 32), The time between the time when the 2 selector signal is switched from L to H (t10 shown in FIG. 32) is the same as the time when the first selector signal is switched from H to L (t4 shown in FIG. 32). It becomes shorter than the time when the selector signal is switched from H to L (t5 shown in FIG. 32).

Thus, the time between the time when the first selector signal is switched from L to H (t9 shown in FIG. 32) and the time when the second selector signal is switched from L to H (t10 shown in FIG. 32). (Hereinafter referred to as LL time) may become extremely small, and the main CPU 131 may not be able to properly detect changes in the first selector signal and the second selector signal. In the present embodiment, the main CPU 131 performs the coin insertion / start check process shown in FIG. 21 every 1.173 ms, but the coin monitoring control CPU 90 is shorter than that time.
The periodic interrupt process shown in FIG. 29 is performed every ms. For this reason, in the periodic interrupt process shown in FIG. 29, the coin supervisory control CPU 90 sets the first selector signal to L (every 1 ms, for example).
1st) → H (2nd) → H (3rd), the second selector signal is set to L (1) at the same timing.
) → L (second) → H (third), the main CPU 131 uses the first first selector signal in the coin insertion / start check process shown in FIG. Although a certain L and the second selector signal L can be specified, since the coin insertion / start check process is performed every 1.1735 ms, the above-described second first selector signal H, The second selector signal L cannot be specified, and the above-described third first selector signal H and the second selector signal H are specified. Accordingly, the main CPU 131 does not specify H as the second first selector signal and L as the second selector signal even though the coin has passed normally. Is determined to be abnormal.

Therefore, in order to prevent the main CPU 131 from determining that the coin passing state is abnormal even though the coin has normally passed through the photo sensor 26 and the photo sensor 27, the upper limit value of the second mismatch counter. Is set to a value larger than the upper limit value of the first mismatch counter. Thereby, the upper limit value of the second mismatch counter in the present embodiment is 7, which is larger than the upper limit value of 5 of the first mismatch counter, so that the second selector signal is changed from L to H.
The time when the first selector signal is switched from L to H is longer by 2 ms than the time when the first selector signal is switched from L to H, and the main CPU 131 appropriately detects coins that are gradually accelerated within the detection range of the photosensors 26 and 27. You may be able to.

In this embodiment, the coin sorting device 10 is configured so that the coin speed on the exit 32 side is faster than the entrance 31 side (the entrance 31 has a vertical path 14a, and the coins on the inclined path 14b are placed in the exit 32). If it is configured so that the speed at the inlet 31 side and the outlet 32 side hardly change,
The upper limit values of the first mismatch counter and the second mismatch counter may be set equal.

FIG. 33 is a diagram showing the light reception error detection processing in steps 420 and 423 described above. As shown in FIG. 33, in step 420-1, the coin supervisory control CPU 90
Sets an initial value (here, a value corresponding to 20 μs) to the light reception error timer.

In step 420-2, the coin supervisory control CPU 90 confirms whether or not the light emission signal is received through the I / O port specified in step 418 or step 421. Further, the coin supervisory control CPU 90 performs step 42 when the light emission signal is received.
The process proceeds to 0-3, and if the light emission signal is not received, the process proceeds to Step 420-4. In addition,
As described above, the light emission signal is distinguished from the light emission pattern, and is not the light emitted from the first light emitting element 261a or the second light emitting element 271a, but the light of the light emitting element illegally inserted from the outside. It is done.

Here, FIG. 34 shows the first selector signal output from the first selector port 94a, the second
The second selector signal output from the selector port 94b, the first light emitting element 261a, and the first
It is a timing chart figure showing the relation at the time of a light reception error of a detection result of light receiving element 261b, and a detection result of the 2nd light emitting element 271a and the 2nd light receiving element 271b. As shown in FIG. 34, the periodic interruption process shown in FIG. 29 occurs, and the first light emission is performed for about 80 μs from the above-mentioned step 402 to step 428 (the time between t1 and t2 shown in FIG. 34). Since both the element 261a and the second light emitting element 271a are off and the main light receiving error detection process is performed during this period, NO is determined in step 420-2 unless any light emitting element is inserted from the outside. . In this case, since the value of the error counter does not exceed a predetermined number (here, 4), NO is determined in step 424 and step 425, and the main CPU 131 determines that the photosensor 26 and photosensor 27 It is determined that the detection result is normal.

On the other hand, if any light emitting element is inserted from the outside between t1 and t2 shown in FIG. 34, YES is determined in step 420-2. In this case, every time the periodic interrupt processing shown in FIG. 29 is performed, the value of the error counter is incremented by 1 in step 420-3, and when the error counter value becomes 4 or more, step 424 and step 425 are performed.
The main CPU 131 determines that the detection results of the photo sensor 26 and the photo sensor 27 are not normal (light reception error). The main CP
If U131 determines that it is a light reception error, the operation of the slot machine 1 is stopped. In this case, the main CPU 131 releases the stop of the slot machine 1 by turning on the power again.

In this embodiment, the coin supervisory control CPU 90 determines that the light reception error is detected by a noise signal from the outside by determining the light reception error on the condition that the value of the error counter has reached a predetermined number (here, 4) or more. May not be determined.

In step 420-3, the coin supervisory control CPU 90 sets the error counter value to 1.
Is added.

In step 420-4, the coin supervisory control CPU 90 updates the value of the reception error timer.

In step 420-5, the coin supervisory control CPU 90 checks whether or not the value of the reception error timer is zero. The coin supervisory control CPU 90 proceeds to the process of Step 420-6 when the value of the reception error timer is 0, and proceeds to the process of Step 420-2 when the value of the reception error timer is not 0.

In step 420-6, the coin supervisory control CPU 90 sets 0 to the error counter.

35 shows the first selector signal output from the first selector port 94a, the second selector signal output from the second selector port 94b, the detection results of the first light emitting element 261a and the first light receiving element 261b, It is a timing chart figure showing the relation at the time of coin jam of the detection result of 2 light emitting elements 271a and the 2nd light receiving element 271b. As shown in FIG.
When the coin is jammed within the detection range of the photosensor 26 and the photosensor 27, the first light emission pattern and the second light emission emitted from the first light emitting element 261a and the second light emitting element 271a.
The light emission pattern is reflected by the coin and received by the first light receiving element 261b and the second light receiving element 271b. In this case, for each periodic interrupt process shown in FIG. 29, the value of the coincidence counter is continuously incremented by 1, and the first condition is that the coincidence counter value becomes the upper limit value.
The selector signal and the second selector signal continue to be held at L. However, when the coin jam is released (t1 shown in FIG. 29), the first selector signal is changed from L to H on the condition that the value of the first mismatch counter becomes the upper limit value of 5, and the second mismatch is detected. On condition that the value of the counter reaches the upper limit value of 7, the second selector signal is changed from L to H, and both selector signals return to the normal state. In step 404 and step 412 of the periodic interruption process of FIG. 29 that is started first after power is supplied to the coin sorting device and a signal is applied to the RESET terminal, the first transmission data transmitted at the previous interruption time. Since there is no second transmission data, in this case, both are processed as 00H.

The coin monitoring control CPU 90 determines the timing demodulated by the photosensor 26 (for example, the time t4 when the first selector signal shown in FIG. 32 becomes L) and the timing demodulated by the photosensor 27 (for example, shown in FIG. 32). Time t5 when the second selector signal becomes L
) Is within a preset reference time (eg, within 100 ms, step 209 shown in FIG. 21), a coin passing through the coin path 14 is detected (eg, step 212 shown in FIG. 21). You may comprise the coin detection means to do. In this case, in addition to the demodulation by the photosensor 26 and the photosensor 27, the photosensor 26 and the photosensor 2
Since the passage of coins is detected, including the timing of demodulation by 7, the slot machine 1
In some cases, the coin sorting device 10 can prevent a coin from being erroneously recognized by a light-emitting element that is illegally inserted from the outside.

The coin monitoring control CPU 90 determines the timing demodulated by the photosensor 26 (for example, the time t4 when the first selector signal shown in FIG. 32 becomes L) and the timing demodulated by the photosensor 27 (for example, shown in FIG. 32). Step 2 shown in FIG. 21 is performed within a preset reference time (for example, within 100 ms) with respect to the interval between the second selector signal L and t5).
If not (09), a coin determination unit that determines that the state is abnormal (for example, 212 shown in FIG. 21, step 213) may be configured. In this case, in addition to the demodulation by the photo sensor 26 and the photo sensor 27, it is determined whether or not the coin passing state is abnormal including the timing of the demodulation by the photo sensor 26 and the photo sensor 27. The slot machine 1 and the coin sorting device 10 may be able to more accurately determine a light emitting element that is illegally inserted from the outside.

The first light emitting element 261a and the second light emitting element 271a constitute a light emitting unit that emits a light emitting pattern including transmission data by modulating light oscillation, and the first light receiving element 261b and the second light receiving element 271b are The coin monitoring control CPU 90 constitutes a light receiving unit synchronized with the light emission of the light emitting unit, and the light emission pattern (for example, the light emission pattern between t1 and t3 shown in FIG. 32, etc.) from the first light emitting element 261a or the second light emitting element 271a Each time light is emitted, the received data included in the light emission pattern received from the first light emitting element 261a or the second light emitting element 271a and the light emission emitted from the first light emitting element 261a and the second light emitting element 271a at the timing of the synchronization. A counting unit (for example, step 41 shown in FIG. 31) that counts the number of times whether or not the transmission data included in the pattern matches (demodulation is successful). −3, step 410-5), and the coin monitoring control CPU 90 first reaches the first reference number (for example, the upper limit value of the first matching counter) (see, for example, FIG. 32). T4 and t5 shown, step 410-7 shown in FIG.
, Step 410-9), and then the number of mismatches reaches the second reference number (for example, the upper limit value of the second match counter) (for example, t9, t10 shown in FIG. 32, step 410-10 shown in FIG. 31). , Step 410-12) may constitute a coin detection unit for detecting coins passing through the passage unit. In this case, when the number of matches and mismatches between the transmission data and the reception data described above is a predetermined number or more, the passage of the coin is detected, so that the slot machine 1 and the coin sorting device 10 are Noise signal (for example, radio wave from mobile phone)
In some cases, it is possible to prevent erroneous recognition of the passage of coins.

The first light emitting element 261a and the second light emitting element 271a constitute a light emitting unit that stops emitting light at a predetermined timing, and the coin monitoring control CPU 90 uses the light receiving unit when the light emitting unit is not emitting light. A coin detection unit that determines that the state is abnormal when the detection result in the light receiving state changes may be configured. Further, the first light emitting element 261a and the second light emitting element 271a constitute a light emitting unit that stops generating light at every predetermined timing, and the coin monitoring control C
The PU 90 detects by the first light receiving element 261b and the second light receiving element 271b when the first light emitting element 261a and the second light emitting element 271a are not emitting light (for example, between t1 and t2 shown in FIG. 34). The counting means (for example, step 424 and step 425 shown in FIG. 29) is configured to count the number of times the result has changed for each predetermined timing, and the coin monitoring control CPU 90 further counts the third reference number (for example, , The coin determination unit (for example, step 426 and step 427 shown in FIG. 29) that determines that the state is abnormal may be configured. In this case, the first light emitting element 2
When an unauthorized light emitting element is inserted from the outside on the condition that the light emitting element 61a and the second light emitting element 261b do not emit light, the slot machine 1 and the coin sorting device 10 recognize the first light receiving element 26.
By detecting a change in the detection result in 1b and the second light receiving element 271b, it may be possible to detect a light emitting element that is illegally inserted from the outside.

The appropriate coin is a coin that enters from the entrance 31 and is discharged from the exit 32.
All other entering objects such as other coins may be treated as inappropriate coins.

The transmission data / reception data RAM 91 need only be configured to store and store transmission data, reception data, etc., and is not limited to a configuration such as a RAM.
OM may be used. In other words, the first transmission data RAM 91a, the first reception data RAM 91b, the second transmission data RAM 91c, and the second reception data RAM 91d are
The transmission data storage means, the first reception data storage means, the second transmission data storage means, and the second reception data storage means may be respectively replaced.

In the embodiment, the coin monitoring control CPU 90 is exemplified as having a RAM, an I / O port, a serial interface, and a CPU, but this may be a coin monitoring control circuit or a coin monitoring control microcomputer.

  In addition, although coin was illustrated as a game medium, a game ball, a medal, a token, etc. may be sufficient.

In addition, although the example which uses the reflection type photosensors 26 and 27 as a sensor which detects the position of a game medium was shown, if a position of a game medium can be detected, a transmission type photosensor or the like may be used. Alternatively, a sensor using a pressure wave such as sound, magnetic force or the like as a medium may be used.

Storage means for storing game media (for example, coins) (for example, a hopper 152, a tray that is provided below the front of the gaming machine shown in FIG. 1 and receives coins paid out from the hopper 152, etc. via the coin return slot 4). And guide means for guiding the game medium to the storage means (for example, the coin passage 14, the slope 14b, the passage between the hopper 152 and the coin return port 4).
And signal transmission means (for example, a first light emitting element 261a, a second light emitting element 271a, a first transmission data RAM 91a, a second transmission data RA) for transmitting a signal to the game medium guided by the guidance means.
M91c, I / O ports 92a, 92b, serial interfaces 93a, 93b, etc.) and signal receiving means (for example, first light receiving element 261b, second light receiving element) for receiving signals transmitted from the game medium guided by the guiding means 271b, first received data RAM 91b, second
Received data RAM 91d, I / O ports 92a and 92b, serial interface 93
a, 93b, etc.) and transmission information generating means for generating information (for example, first transmission data, second transmission data, etc.) to be included in the signal transmitted from the signal transmitting means (for example, FIG. 27 RESET interrupt processing, step 302 to step 305, periodic interruption process of FIG. 29, step 403, etc.) and whether the guide means guides the game medium based on the information generated by the transmission information generating means and the signal received by the signal receiving means. Since there is a guidance determination means (for example, FIG. 29 periodic interruption processing, FIG. 31 selector signal output processing, etc.), it is transmitted rather than grasping the position of the game medium by continuous light such as conventional lighting only. In some cases, the position of the game medium can be more reliably grasped based on the information and the received signal. In other words, the detection operation of game media is affected by natural ambient light from outside, environmental disturbance light such as light quantity change and diffuse reflection due to dust, and artificial light, and it can eliminate malfunctions and malicious illegal game media throwing action, In some cases, it is possible to provide a highly reliable gaming machine to a gaming store that uses a gaming machine that employs the present technology.

Note that random number data generation means (for example, FIG. 27 RESET interrupt processing, step 302 to step 305, FIG. 2) for generating random number data (for example, first transmission data, second transmission data, etc.)
The transmission information generating means includes a plurality of bit strings (for example, 1 (000 0001B in binary notation) based on the random number data generated by the random number data generating means. ~ 126 (111 1110B in binary notation)) is generated as the information, for example, a specific bit string (for example, first transmission data, second transmission data, etc.),
The signal transmission unit is configured to convert the specific bit string into a pulse signal (for example, D1 to D7 in FIG. 30) and transmit the pulse signal, and to receive the pulse signal (for example, D1 to D7 in FIG. 3) received by the signal reception unit. ) Is included in the bit string obtained by converting,
Since the guidance determination means determines that the guidance means is guiding the game medium (eg, determination result of step 410-2 YES), the transmission information is generated internally.・ In some cases, artificial adverse effects can be further eliminated. Of course, by generating random number data by the random number generation means and including the information obtained as a result in the transmission signal, the operation of the position detection means of the game medium including the guidance determination means can be grasped by an external person or some device. In particular, it may be possible to eliminate a particularly malicious illegal game medium throwing action. However, a random number generation means may not be provided, and the plurality of bit strings described above may be stored in order and selected as the information according to the order. For example, 1, 5, 10,
A numerical sequence such as 3, 100,... Is stored in the storage means, and at the first transmission signal timing, the first stored 1 is selected from the numerical sequence and converted into a binary number. The light emitting element is turned on in the lighting mode based on the above, and at the next signal transmission timing, the next stored 5 is selected from the numerical sequence, and light is emitted in the lighting mode based on the information converted into binary numbers. You may make it light an element. Even in this way, the detection operation of the game medium is affected by environmental disturbance light or artificial light, and it is possible to eliminate malfunctions and malicious illegal game medium insertion actions, and the player and the game using this technology In some cases, it is possible to provide a highly reliable gaming machine to a gaming store that uses the machine.

Each time the signal transmission means transmits a signal (for example, FIG. 29 periodic interrupt processing that occurs at a constant period), the transmission information generation means performs the transmission information generation means based on the random number data generated by the random number data generation means. It is configured to generate information, and the guidance determination means determines that the guidance means does not guide the game medium, and then continues for a predetermined number of times (for example, counting by a coincidence counter, etc.) and receives the received pulse signal. When the specific bit string is included in the bit string obtained by converting, the guidance determining means determines that the guiding means is guiding the game medium, and the guidance determining means is that the guiding means is the game medium. It is determined that the bit string is obtained by converting the received pulse signal continuously for a predetermined number of times (for example, counting by a mismatch counter) after it is determined that the information is being guided. When the bit string is not included, the guidance determination means determines that the guidance means does not guide the game medium, and therefore the specified bit string obtained by converting the received pulse signal continuously for a predetermined number of times. In this case, the guidance determination means can determine that the guidance means guides the game medium, thereby preventing the malfunction of the guidance determination means due to noise such as ambient light. As a result, the reliability of the gaming machine may be further improved.

Further, when the specific bit string is not included in the bit string obtained by converting the received pulse signal continuously for a predetermined number of times (for example, counting by a mismatch counter, etc.), the guide determining means is the game medium. A similar effect may be obtained with respect to a technique for determining that the user is not guiding the user.

Here, it is exemplified that the predetermined number of times is continued. However, the present invention is not limited to this, and the specific bit string is included or included in a bit string obtained by converting a pulse signal received a predetermined number of times or more within a predetermined period. If not, the guidance determination means may be configured to determine that the guidance means is guiding or not guiding the game medium. For example, when the specific bit string is included or not included in the bit string obtained by converting the pulse signal received four or more times at five consecutive determination timings, the guide determining means It may be determined that the game medium is being guided or not being guided.

The guide means is composed of one or a plurality of areas (for example, a detection range of the photosensor 26, a detection range of the photosensor 27, etc.), and the guidance determination means is one or a plurality of areas (for example, photosensors). 26, 27, etc.) and the determination result of the one or more guidance determination means is changed in a specific order (for example, FIGS. 22 to 26, etc.), it is determined that the guidance of the game medium by the guidance means is completed. Since a guidance completion determination means (for example, coin insertion / start check process in FIG. 21) is provided (for example, determination result YES in step 212),
By providing guidance determining means corresponding to a plurality of areas, the moving direction and speed of the designed game medium and the size of the game medium related to the moving direction can also be controlled as detection targets. For example, if you want to detect the position of a game medium for only a single area,
Whether the game medium is going backwards or moving in the normal direction can not be detected, but by monitoring multiple areas, it is possible to grasp these as well, and the inside and outside of the detection range of the photo sensor is connected to the thread By reciprocating the game medium, it is possible to prevent an illegal act such as causing the game machine to detect as if a game medium that was not actually inserted was inserted, and to make the gaming machine more reliable. There is a case. In addition, it is needless to say that the embodiment and the modification examples may be changed without departing from the scope of the present invention.
