Abstract

PROBLEM TO BE SOLVED: To easily and surely prevent counting for the purpose of illegality by judging a normality only unless the detecting output of a receiving part at a transmitting part side which is not driven in a second state exists and storing the coefficient value of a counter when the phase difference of detecting signals of a receiving part is within a prescribed range in the first state. SOLUTION: The counter 9 counts the output number of the detecting signals of a second light receiving equipment 4b. A judging means 10 judges the normality only when phase difference between the detecting signal of the first light receiving equipment 3b and that of the second light receiving equipment 4b is within the prescribed phase difference range which is stored in a transfer storage means when a change-over signal from a changing-over means 6 is in the first state. When the change-over signal from a changing-over device is in the second state, the normality is judged only unless the detecting signal from the light receiving equipment at a light emitting side which is not driven is outputted. When a normal signal is outputted and also the state is except the normal one, an announcing device 12 is made to display or ring-out an abnormality and communication about it is executed to a whole computer 20 by a communicating means 13.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game medium counting device for counting game media, and more particularly to a game medium counting device for preventing illegal counting.

[0002]

2. Description of the Related Art In a game store such as a pachinko parlor, a game medium counting device for counting game media such as pachinko balls obtained by a player for exchanging prizes is installed.

A conventional game medium counting device of this type is provided with an inclined traveling path on which the game medium rolls and falls under its own weight, and a pair of light-emitters is provided so that light is blocked when the game medium passes through the traveling path. And a light receiver, the light receiver detects the interruption of the light by the game medium, and the detection signal is counted.

However, in such a conventional game medium counting apparatus, a light-emitting body such as a light emitting diode is inserted from a game medium receiving port or the like to perform blinking driving, or an antenna is inserted to intermittently emit strong electromagnetic waves. An illegal act of counting by generating a detection signal is performed.

[0005] In particular, in recent years, a game machine provided with a game medium counting device for each game console has become widespread. In such a case, it is difficult for a store clerk to monitor all the game consoles. It is easy for cheating to take place, causing great damage to the store.

Conventionally, in order to prevent such misconduct, two light emitting and receiving devices are conventionally provided at the upstream and downstream sides of the running path, and the detection signals of the two light receiving devices determined by the running speed of the game medium are provided. There has been proposed a technique (Japanese Patent Laid-Open No. 8-182848) for judging a fraudulent activity based on whether or not the phase difference is matched.

According to this prior art, even if the luminous body is inserted into the game medium counting device for an illegal purpose and is made to blink on one side of one of the two sets, the detection of the two light receivers is detected. Since the signal phase differences do not match, fraud can be detected and fraudulent counting can be prevented.

Conventionally, in addition to the light emitting and receiving device provided on the traveling path, a light receiving device for fraud detection is separately provided near the regular light emitting and receiving device at a position where the game medium does not travel. A technique (Japanese Unexamined Patent Publication No. Hei 7-13390) for judging a fraudulent act when the photodetector for fraud detection outputs a detection signal has also been proposed.

According to this prior art, even if the illuminant is inserted into the game medium counting device for the purpose of fraud and flickers, the fraud-detecting light receiver also outputs a detection signal, so that fraud can be detected. Counting can be prevented beforehand.

[0010]

However, in the former method using the phase difference between the detection signals of the two light receivers, for example, two light emitters are inserted near the two light emitters and receivers, respectively. In addition, when the two light emitters are blinked with a predetermined time difference, there is an inconvenience that fraud cannot be detected.

In the latter method, a special photodetector for fraud detection is provided at a position where game media does not pass, even if light is irradiated so as to avoid the special photodetector for fraud detection, fraud is detected. There was a disadvantage that it could not be detected. In addition, since the light receiver is provided at another position where the game medium does not travel, an extra space is required. An object of the present invention is to provide a game medium counting device that solves such a problem.

[0012]

In order to achieve the above object, a game medium counting device according to a first aspect of the present invention is arranged such that a game medium runs on a traveling path and a predetermined distance along the traveling path. A first and a second detection device, which are respectively installed at two places and are configured as a pair by a transmission unit and a reception unit for detecting a game medium passing through the travel path, and the first and second detection devices;
Switching timing of the switching condition storage means between a first state in which both transmitting units of the detecting device are driven and a second state in which only one of the first and second detecting units is driven. Switching means for switching by a counter, a counter for counting the detection signal of the receiving unit of the detecting device on the transmitting unit side driven in the second state, and in the first state,
Only when the phase difference between the detection signals of the respective receiving units of the first and second detection devices is within a predetermined range, it is determined to be normal, and the second
In the state of the above, the determination means for determining normal only when there is no detection output of the receiving part of the transmitting part not driven, and the count value of the counter at the end of counting when the determination means determines normal And a count value storage means for storing the count value.

With this configuration, in the first state switched by the switching means, a detection signal is output from each of the receiving units of the first and second detection devices when the game medium passes through the traveling path, Only when the phase difference between the respective detection signals is within a predetermined range is the normality determined by the determination means. If it is determined that the game is normal, the count value of the counter at the end of counting is stored in the count value storage means as the count value of the game medium.

Further, in the second state switched by the switching means, only one of the first and second detecting devices is driven, so that the game medium is moved on the traveling path. , A detection signal is output from only one of the receiving units, and this detection signal is counted by a counter. Then, only when there is no detection output of the receiving unit on the non-driven side, it is determined by the determining unit that it is normal. If it is determined that the count is normal, the count of the counter at the end of counting is stored.

The switching timing of the first state and the second state by the switching means is stored in the switching condition storage means, and is sequentially switched according to the stored switching timing.

Therefore, in the first state in which the two transmitting units are driven, when the illuminant is inserted and blinked to make it appear that the game medium is running for an unauthorized purpose, Since light does not reach both the first and second detection devices and the detection signal is output only from the reception unit of one of the detection devices, the phase difference between the detection signals of the two reception units is within a predetermined range. Is not satisfied, fraud is immediately detected. Further, in the second state in which only one of the transmitting units is driven, if the light emitter is turned on and off for a fraudulent purpose near the detecting device on the transmitting unit side that is not driven, the transmission that is not driven is performed. Since the detection output is generated from the unit, the fraud is immediately detected.

In the second state, the side of the detecting device which is not driven for fraudulent purpose is not affected by the light emission, and the vicinity of the detecting device which is driven for fraudulent purpose so as not to be affected by light emission. When the light-emitting body is turned on and off, the fraud is not detected, but the first and second states are sequentially switched by the switching means. Therefore, the fraud is immediately detected when the state is switched to the first state.

In the case where two light emitters are blinked with a predetermined time difference near two detecting devices for the purpose of fraud, in the second state where only one of the transmitters is driven, the driving is performed. Since a detection output is also generated from the receiving unit that has not been subjected to the illegal operation, the illegality is immediately detected. In the case of such a fraud, in the first state in which the two transmitting units are driven, if the phase difference between the two detection signals falls within a predetermined range, no fraud is detected, Since the first and second states are sequentially switched by the switching means, improper operation is immediately detected when the state is switched to the second state.

A game medium counting device according to a second aspect of the present invention is provided at a traveling path on which a game medium travels and at two places at a predetermined distance along the traveling path, and passes through the traveling path. First and second detection devices each configured as a pair by a transmission unit and a reception unit that detect a game medium;
Switching between a first state in which both transmission units of the first and second detection devices are driven and a second state in which only one transmission unit of the first and second detection devices is driven Switching means for switching according to the switching timing of the condition storage device; first and second counters for respectively counting detection signals of the respective receiving units of the first and second detection devices; 1, it is determined to be normal only when the difference between the count values of the second counter is from zero to the number of game media that can exist between the two locations on the travel path, and in the second state, the drive is determined to be normal. Determining means for determining that the output is normal only when the count output of the counter of the transmitting unit that is not performed is zero,
When the determination means determines that the count is normal, the count value of one of the first and second counters at the end of counting is stored in the first state, and at the end of counting in the second state. And a count value storage means for storing the count value of the counter on the side of the transmitting section being driven.

With this configuration, in the first state switched by the switching means, a detection signal is output from each of the receiving units of the first and second detection devices when the game medium passes through the traveling path, Each detection signal is counted by the first and second counters, respectively. Only when the difference between the count values of the first and second counters is from zero to the number of game media that can exist between the two locations on the travel path, the determination unit determines that the game medium is normal. If it is determined to be normal, the first at the end of counting,
The count value of any one of the second counters is stored in the count value storage means as the count value of the game medium.

Further, in the second state switched by the switching means, only one of the first and second detecting devices is driven, so that the game medium is moved on the traveling path. , A detection signal is output from only one of the receiving units, and this detection signal is counted by a counter. Then, only when the count output of the counter not driven is zero, the determination means determines that it is normal.
If it is determined that the count is normal, the count of the counter of the driven transmitting unit at the end of counting is stored.

Therefore, when one light emitter is inserted and blinked for an unauthorized purpose, in the first state in which the two transmitting units are driven, the detecting device outputs only from the receiving unit of one detecting device. Since the difference between the count values of the first and second counters does not fall within the normal range, fraud is immediately detected. Further, in the second state in which only one of the transmitting units is driven, if the light emitter is turned on and off for a fraudulent purpose near the detecting device on the transmitting unit side that is not driven, the transmission that is not driven is performed. Since a counter output is generated from the counter on the unit side, fraud is immediately detected.

In the second state, the side of the detecting device which is not driven for the purpose of fraud is not affected by the light emission, and the vicinity of the detecting device which is driven for the purpose of fraud is prevented so as not to affect the light emission. When the light-emitting body is turned on and off, the fraud is not detected, but the first and second states are sequentially switched by the switching means. Therefore, the fraud is immediately detected when the state is switched to the first state.

In the case where the two light emitters are blinked with a predetermined time difference near two detection devices for the purpose of fraud, in the second state, a counter output is generated from the counter which is not driven. Therefore, fraud is immediately detected.
In the case of such misconduct, in the first state, 2
If the difference between the count values of the two counters falls within the normal range, no fraud is detected,
Since the second state is sequentially switched, fraud is detected immediately upon switching to the second state.

[0025]

Embodiments of the present invention will be described below with reference to the drawings. For example, in the case where a pachinko ball counting device is provided for each pachinko machine, the prize balls by the pachinko game are discharged to a ball box (not shown) at the lower front side of the pachinko machine, and an operation lever (not shown) of the ball box is provided. ) Is operated, an opening / closing shutter (not shown) of the ball box is opened, and the pachinko ball falls to the pachinko ball counting device. As shown in FIG. 4, the pachinko ball counting device (game medium counting device) includes a plurality of inclined traveling paths 2, 2,... Which receive the pachinko balls 1 dropped from above and roll and drop by their own weight. During rolling and falling along each of the running paths, they are counted and fall to a lower tank (not shown).

At two locations on the upstream side and the downstream side of each traveling path 2, a pair of floodlights (transmitting sections) 3 a so that light is blocked by pachinko balls 1 passing on both sides so as to sandwich the traveling path 2. A first detector 3 composed of a light receiver (receiver) 3b and a second detector 4 composed of a light transmitter (transmitter) 4a and a light receiver (receiver) 4b forming a pair are provided.

For this reason, when the pachinko balls P pass through the traveling path, the passage of the pachinko balls P is detected by the respective detection signals of the two upstream and downstream light receivers 3b, 4b. The optical axis from the light projectors 3a, 4a to the light receivers 3b, 4b is set so that the pachinko balls 1 can be detected even when the plurality of pachinko balls 1 run continuously on one traveling path 2. The projector 3a is slightly displaced from the center of 1
4a and light receivers 3b and 4b are provided.

FIG. 1 shows the first and second detecting means 3 and 4 at two locations on the upstream side of the traveling path 2, on the upstream side and on the downstream side of the traveling path 2.
1 shows a configuration of an electronic circuit unit according to an embodiment for counting the number of pachinko balls passing through a travel path.

In FIG. 1, the light emitters (transmitters) 3a and 3b of the first and second detectors are driven by the driving means 5 to emit light toward the respective light receivers (receivers) 4a and 4b.

The switching means 6 switches the analog switch 8 based on the switching timing stored in the switching condition storage means 7.
a, 8b, by turning on or off, the first and second detectors 3, 4
Are both driven (first state) and one of the first and second projectors 3a and 4a of the first and second detectors 3 and 4 (for example, an unauthorized A state in which only the second projector 4b) located farther from the dropping port of the pachinko ball into which the luminous body is inserted for the purpose is switched to a driven state (second state), and the first and second states are represented. The signal is output to the determination means 10.

The switching condition storage means 7 stores a time (for example, 1
The switching means outputs a switching signal for each stored time or number of balls to sequentially switch between the first and second states. .

The switching timing and other conditions stored in the switching condition storage means 7 are determined by a command from the hall computer at regular time intervals or each time the player is changed (detecting that a pachinko ball is not shot for a predetermined time). Re). Alternatively, a plurality of types of switching timing may be stored, and switching may be performed at a switching timing randomly selected by the switching device.

The counter 9 counts the number of outputs of the detection signal of the second light receiver 4b. When the switching signal from the switching unit 6 is in the first state, the determining unit 10 determines whether the first light receiver 3
b is determined to be normal only when the phase difference between the detection signal b and the detection signal of the second light receiver 4b is within the range of the predetermined phase difference stored in the phase difference storage means 11, and the switching signal of the switching device is determined. Is in the second state, a normal signal is determined and a normal signal is output only when the detection signal is not output from the light-receiving receiver that is not driven, and Causes the notification device (a lamp, a buzzer, etc.) 12 to display or sound the abnormality, and causes the communication means 13 to communicate the fact to the hall computer 20.

The counting end detecting means 14 outputs a counting end signal when the detection signal from the second photodetector 4b of the second detecting means 4 on the downstream side is not output even after a certain period of time. When the normal signal is output from the means 10, the count value of the counter 9 is stored in the count value storage means 15, and the counter 9 is reset to zero.

It is to be noted that the count value end detection signal may be output after a lapse of a predetermined time after the detection signal is not output on all the running roads, instead of on every running road.

The adder 16 adds the count values output from the respective count value storage devices for each of the traveling paths 2, 2,... And outputs the result to the printer 17 and the card processor 18.

Next, the operation of the electronic circuit section of FIG. 1 will be described.
When the player wants to count the number of pachinko balls 1 accumulated in the ball box, when the operating lever of the ball box is operated, the opening / closing shutter opens and the pachinko balls 1 in the ball box drop to the pachinko ball counting device, and a plurality of pachinko balls are counted. Rolls down along the traveling paths 2, 2,... Due to its own weight.

The first state, that is, the first and second projectors 3a, 3a of the first and second detectors 3, 4 are switched by the switching means 6.
In a state in which both pachinko balls 4a are driven, a signal indicating the first state is sent to the judging means 10, and when the pachinko ball 1 passes through the traveling path 2, the upstream and downstream pachinko balls 1 have a phase difference determined by the traveling speed. First and second photodetectors (receivers) 3b, 4b
, A detection signal is output from each of them. If the phase difference is within the range of the predetermined phase difference stored in the phase difference storage means 11, it is determined that the phase difference is normal.

In the second state, that is, when only the second light emitter 4a of the second detecting device 4 is driven by the switching means 6, the first upstream member when the pachinko ball 1 travels is driven. No detection signal is output from the light receiver 3b, and only the downstream second light receiver 4b outputs a detection signal. For this reason, the determination means 10 receiving the signal indicating the second state from the switching means 6 determines that the state is normal, and outputs a normal signal.

When all the pachinko balls have passed through the traveling path, an end signal is output from the counting end detecting means 14 after a set time (for example, several seconds) has elapsed. When the count value storage means 15 receives the normal signal from the determination means 10 and receives the end signal, it outputs the stored count value of the counter 9 to the addition means 16. The counter 9 and the count value storage means 15 are reset to zero by the end signal.

In this way, the count values of all the running paths 2, 2,... Are output to the adding means 16 and added, and the total of the counted values of the pachinko balls passing through all the running paths 2, 2,. The value is transmitted from the communication device 13 to the hall computer 20 and output to the card processor 18 so that the count value is recorded on the card inserted by the player, or is output to the printer 17 to output the count value. Is printed out.

By the way, in order to make the pachinko balls count on the running path for the purpose of fraudulently as if the pachinko balls were not actually running, for example, an illuminator was opened and closed by opening and closing a shutter at the bottom of the ball box. For example, when the first light receiver 3b on the upstream side is turned on and off so as to receive light, in the first state in which the first and second light emitters 3a and 4a are both driven, the upstream side A detection signal is output from the first light receiver 3b even if the pachinko ball does not pass by blinking of the light emitter, but the second light receiver 4b on the downstream side far from the illegally inserted light emitter is provided with a light emitting element. No detection signal is output without being affected by blinking. For this reason, the condition that the phase difference between the two detection signals is within a predetermined range is not satisfied.
0 means that fraud is immediately detected.

In the second state in which only one of the two projectors 3a, 4a (eg, the downstream projector 4a) is driven, the upstream first projector 3a that is not driven is driven. When a light emitting body that has been illegally inserted nearby is blinked and a detection signal is output from the first light receiver 3b, the judging means 10 immediately detects the illegality.

Further, by inserting a plurality of light emitters and blinking them, even if the first and second light receivers 3b and 4b output detection signals together, the two detection signals have a predetermined phase difference. Therefore, the judging means 10 immediately detects the fraud.

When a fraud is detected, the alarm means, such as a lamp or a buzzer, turns on or sounds, and is transmitted to the hall computer by the communication means 13.

In the second state in which only the second light emitter 4a is driven, the first light receiver 3b is not affected so as to be close to the second light receiver 4b for unauthorized purposes. When the light emitter is inserted and blinked, no detection signal is output from the first light receiver 3b, so that no fraud is detected. However, after a certain period of time, or when the count value of the counter due to this illegality reaches a predetermined value, the switching means 6 switches to the first state, so that the phase difference between the two detection signals in the first state is within the predetermined range. No fraud is detected immediately.

In the first state in which the first and second light projectors 3a and 4a are both driven, the second light projector 3a,
If the two light emitters are blinked near the first and second detection devices 3 and 4 with a time difference within the range of the predetermined phase difference, fraud is not detected, but the second state is changed from the first state to the second state. When the state is switched by the switching means 6, the detection signal is generated from the first light receiver 3b on the non-driven side. Thus, the fraud is immediately detected by the first and second switching.

It is to be noted that the second which drives only one of the projectors is used.
In the state (1), the first projector and the second projector may be sequentially switched. In this case, as shown in FIG.
A counter 9 'is also provided on the side of the light receiver 3b, and in the second state, the two counters 9 on either side being driven,
The count value storage means 1 stores any one of the count values 9 '
5 may be output.

In the embodiment of FIG. 1, the phase difference between the detection signals of the first and second detection devices 3, 4 determined by the running speed of the pachinko balls in the first state is used for fraud detection. However, since a large amount of pachinko balls flow into the traveling path and the pachinko balls travel on the traveling path continuously in a daisy chain, the traveling speed may be reduced.

FIG. 3 shows a configuration of an electronic circuit section according to another embodiment of the present invention which can cope with such a case. The description of the same parts as those in FIGS. 1 and 2 will be omitted.

The first and second counters 9a and 9b count the number of output of each detection signal of the first and second light receivers 3b and 4b, respectively. The count values of the first and second counters are reset to zero each time the first and second states are switched by the switching means 6.

When the switching signal from the switching means 6 is in the first state, the injustice judging means 10 stores the difference between the count values of the first and second counters 9a and 9b in the ball number storage means 19. It is determined to be normal only when the number of pachinko balls that can exist between the two upstream and downstream locations where the first and second detection means 3 and 4 of the stored traveling path are installed is determined, and the second state In Case of,
Only when the count value of the first counter on the light emitting side that is not driven is zero, it is determined to be normal, and a normal signal is output. Otherwise, the lamp or buzzer of the notification device 12 is turned on or off. The sound is made to sound, and the communication circuit 13 communicates the fact to the hall computer 20.

The count value storage means 15 accumulates and stores the count value of the second counter 9b every time the switching means 6 switches when the normal signal is output from the determination means 10.

The counting end detecting means 14 outputs a counting end signal when the detection signal from the photodetector 4b of the downstream second detecting device is not output even after a certain period of time. When the signal is output, the accumulated count value stored in the count value storage means 15 is output to the adding means 16 and the first and second counters 9 are output.
Reset the values of a and 9b to zero.

Next, the operation of the electronic circuit section of FIG. 3 will be described.
When the player wants to count the number of pachinko balls accumulated in the ball box, when the operating lever of the ball box is operated, the opening / closing shutter is opened and the pachinko ball 1 in the ball box falls to the pachinko ball counting device, and a plurality of runnings are performed. Rolls down along the roads 2, 2,.

The first state, that is, the first and second light emitters 3a of the first and second detectors 3 and 4 by the switching means 6,
4a is switched to the driven state, the first and second counters 9a and 9b are reset, and the pachinko ball 1
When passing through the traveling path 2, the first and second light receivers 3b, 4b
Output each detection signal, and are counted by the first and second counters 9a and 9b, respectively.

Then, the first and second counters 9a and 9b
Is different from the number of pachinko balls that can exist between the first and second detectors 3 and 4 stored in the number-of-balls storage means 19 (ie, the number of pachinko balls that can be connected in a rosary). If it is within the range of), it is determined to be normal.

Further, the switching device 6 sets the second state,
That is, in a state where only the second light projector 4a of the second detection device 4 is driven, no detection signal is output from the upstream first light receiver 3b when the pachinko ball travels, and the downstream first light receiver 3b is not driven. The detection signal is output only from the second light receiver 4b. For this reason, only when the count value of the first counter 9a is zero, the judging means 10 judges that it is normal and outputs a normal signal.

After the pachinko ball finishes running and a set time (for example, several seconds) elapses and an end signal is output from the count end detecting means 14, the count value storing means 15 outputs the normal signal of the judging means 10. If so, the stored count value of the second counter 9b is output to the adding means 16. First and second counters 9a and 9b and count value storage means 15
Is reset to zero by the end signal.

In this way, the count values for all the running paths are added by the adding means 16 and transmitted from the communication means 13 to the hall computer 20 and output to the card processor 18 so that the player can The count value is recorded on the inserted card and output to the printer 17 to print out the count value.

By the way, in order to make the pachinko ball seem to be traveling for an unauthorized purpose, the luminous body was inserted from the opening / closing shutter at the bottom of the ball box and blinked near the first light receiver 3b. In this case, in the first state in which the first and second light projectors 3a and 4a are both driven, the detection signal is output from the first light receiver 3b on the upstream side even if the pachinko ball does not pass due to the flashing of the light emitter. Although it is output, the second light receiver on the downstream side is not affected by the blinking of the light emitting body 4b, and no detection signal is output. Therefore, only the first counter 9a counts the detection signal, and the second counter 9b remains at zero.
Since the condition that the difference between the count values of the second counters 9a and 9b is within the above range is not satisfied, the determination means 10 immediately detects the fraud.

In the second state where the first projector 3a is not driven, the illuminator that has been illegally inserted near the upstream first light receiver 3b that is not driven blinks,
When the detection signal is output from the first light receiver 3b and the first counter 9a counts, the judging means 10 immediately detects the fraud.

When a fraud is detected, the notifying means 12 such as a lamp or a buzzer is turned on or sounds, and transmitted to the hall computer 20 by the communication means 13.

In the second state where only the second light emitter is driven, the light emitter is inserted near the second light receiver 4b so as not to affect the first light receiver 3b. If it flashes, no fraud is detected. However, when a predetermined time elapses or when the count value of the counter due to this illegality reaches a predetermined value, the switching means 6 switches to the first state, so that the first and second counters 9a, 9b are switched in the first state. Since the difference between the count values does not fall within the predetermined range, fraud is immediately detected.

When a plurality of light emitters are inserted in the first state and the detection signals are output from both the first and second light receivers 3b and 4b, the total of the first and second counters 9a and 9b is increased. The difference between the numerical values becomes zero, and no fraud is detected. However, similarly, when the predetermined time elapses or the number of balls counted by the counter reaches the predetermined value, the state is switched to the second state, so that fraud is immediately detected.

In the first state, the two luminous bodies are respectively connected to the first and second detectors 3 and 4 as described above.
Is blinked with a time difference within the range of the predetermined phase difference, the fraud is not detected because the difference between the count values of the first and second counters 9a and 9b is within the predetermined range. Since the state is switched to the second state, fraud is immediately detected due to the detection signal generated from the first light receiver 3b on the non-driven side. As described above, the fraud is immediately detected by switching the first and second states.

It is to be noted that a second driving device for driving only one of the projectors is provided.
In the state (1), the first projector 3a and the second projector 4a may be sequentially switched. In this case, the count value of the driven counter may be output.

In the above description, a pair of a light transmitter and a light receiver has been exemplified as the detection device. However, a transmitter and a receiver constituted by coils are provided so as to sandwich a traveling path, and the passage of a pachinko ball is performed. You may make it detect with a receiver.

Even if an antenna or the like is brought close to the receiver for improper purpose and a strong electromagnetic wave is applied to the light receiver or receiver to generate a detection signal incorrectly, both of the two projectors (or transmitters) are driven. By switching between the state 1 and the second state in which only one is driven, illegality can be detected in the same manner as in the case of illegal light blinking. The present invention is not limited to pachinko balls, but may be applied to any game medium that can be detected while running.

[0070]

As described above, according to the present invention, two detection devices are provided on the upstream and downstream sides of the game medium traveling path, and are switched between a state in which both are driven and a state in which only one is driven. Therefore, counting for an unauthorized purpose can be easily and reliably prevented.
