【Example】
An embodiment of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 and 2, a counting device is installed in the gaming machine. A host computer as a centralized management device is installed in a place away from the game hall or in a separate room adjacent to the game hall.
The counting device is formed by arranging the snorkel rails 16 that are aligned flow paths in parallel, and each snorkel rail 16 is configured to be able to flow down so that pachinko balls that are game media straddle the adjacent snorkel rails 16. Yes. The end portion of the slatted rail 16, a shutter over 17 to allow a stream of pachinko balls are retracted to prevent capable and downward stream of pachinko balls to protrude upward is provided. A light emitting element 18 that can project light onto a pachinko ball that flows down through a gap between adjacent snorkel rails 16 is disposed above the snorkel rail 16 . A light emitting diode is used for the light emitting element 18.
[0016]
Below the snorkel rail 16, it is possible to receive the light of the light emitting element 18 so as to face the light emitting element 18, and when the falling pachinko ball blocks the light of the light emitting element 18, it is an electric signal obtained by converting the optical signal. A light receiving element 19 capable of outputting a certain detection signal is provided. The detection signal of the light receiving element 19 is amplified by an amplification circuit (not shown), and a comparison circuit (not shown) compares the amplified detection signal with a reference level and outputs a portion larger than the reference level as a pulse signal. Similarly, a synchronization circuit (not shown) generates a pulse signal in synchronization with the light emission period of the light emitting element 18, and when the generated pulse signal and the output pulse signal are synchronized, an L level signal is generated. When the output is not synchronized, an H level signal is output, and the counter circuit adds the number of outputs of the H level signal to the number of balls as an addition signal.
[0017]
A laser diode 25 that is a light projecting unit for projecting light onto the road surface of the snowboard rail 16 is disposed above the snowboard rail 16. An oscillator 21 for taking the light emission timing of the laser diode 25 is provided, and the oscillator 21 is connected to the laser diode 25 via a modulation circuit 22 and an amplification circuit 23. The laser diode 25 is provided with an output control circuit for controlling the amount of laser light in accordance with the amount of received light and compressing the received light signal to the input / output range of the internal circuit.
In front of the laser diode 25, a light projecting lens is provided for narrowing the emitted light of the laser diode 25 into a spot-like beam. A light receiving lens is provided for capturing the reflected light diffusely reflected on the road surface of the snorkel rail 16 and forming an image on the photodiode 31 which is a position detection unit.
[0018]
The photodiode 31 generates an electric current when irradiated with laser light, but is divided into output terminals at both ends according to the center of gravity position and the amount of light received on the light receiving surface. As a result, when the center of the light receiving surface of the photodiode 31 is zero and the length of the light receiving surface of the photodiode 31 is L, the imaging position P is obtained by the equation P = L (I−Ia) / 2 (I + Ia). be able to.
I: current value from the output terminal from one end, Ia: current value from the output terminal at the other end.
From the above equation, when the image is formed at the center of the light receiving surface of the photodiode 31, it is configured such that I = Ia, and at that time, the image formation position P = 0.
[0019]
That is, if the light from the laser diode 25 strikes the road surface of the snocorail 16 and is reflected, and the reflected light forms an image at the center of the light receiving surface of the photodiode 31, foreign matter enters the counting device and the snocorail 16 When a foreign object is placed on the road surface, the position where the reflected light of the laser diode 25 forms an image on the light receiving surface of the photodiode 31 is shifted from the center of the light receiving surface, and I ≠ Ia, so that the entry of the foreign material can be determined.
[0020]
Current-voltage conversion circuits 32 and 32a for converting a current value into a voltage value are connected to each output terminal of the photodiode 31, respectively. Amplifying circuits 33 and 33a for amplifying the voltage value to a certain level are connected to the voltage conversion circuits 32 and 32a, respectively. Detection circuits 34 and 34a are connected to the respective amplification circuits 33 and 33a. The detection circuits 34 and 34a are input with pulse signals having the same period as the light emission timing by the oscillator, and are driven by amplitude modulation to suppress noise. Therefore, the light reception signal is also modulated, and is for demodulating the modulated light reception signal.
[0021]
The AD conversion circuits 35 and 35 a are connected to the detection circuits 34 and 34 a, and the light reception signals from the AD conversion circuits 35 and 35 a are output to the foreign object entry determination unit 36. The foreign object entry determination unit 36 is a calculation unit. When light reception signals are output from the AD conversion circuits 35 and 35a according to a control signal of a control unit (not shown), both light reception signals are compared with each other. Since I = Ia, an image is formed at the center of the light receiving surface of the photodiode 31, and it is determined that the light of the laser diode 25 is hitting the road surface of the snocorail 16, and a normal signal is output. Since I ≠ Ia, the image is shifted from the center of the light receiving surface of the photodiode 31, and it is determined that the light from the laser diode 25 hits the foreign matter on the road surface of the snocorail 16. A signal is output.
[0022]
The foreign matter entry signal of the foreign matter entry determination unit 36 is output to the drive circuit 41, and the drive circuit 41 can supply the necessary current to the actuator 42. An air cylinder is used as the actuator 42. The foreign matter restraining member 45 stands by at a position above the snorkel rail 16 and is configured to descend by the output of the actuator 42 so as to sandwich the foreign matter with the road surface of the snook rail 16.
[0023]
Next, the operation will be described.
The laser light from the laser diode 25 is spotted on the road surface of the snocorail 16 by the light projecting lens, and is reflected by the road surface of the snocorail 16. The reflected light is diffused, it is condensed by the light receiving lens, so that strikes the light receiving surface of the Hotodai diode 31. The photodiode 31 outputs current values I and Ia corresponding to the position of the light receiving surface where the reflected light strikes from both output terminals.
[0024]
The current value I output from one output terminal of the photodiode 31 is converted into a voltage value by the voltage conversion circuit 32, the voltage value is amplified to a constant level by the amplification circuit 33, and the received light signal is demodulated by the detection circuit 34. Then, it is converted into a digital value by the AD conversion circuit 35 and output to the foreign matter entry determination unit 36.
Similarly, the current value Ia output from the other output terminal of the photodiode 31 is converted into a voltage value by the voltage conversion circuit 32a, the voltage value is amplified to a constant level by the amplification circuit 33a, and the received light signal is detected by the detection circuit 34a. Is demodulated, converted into a digital signal by the AD conversion circuit 35 a, and output to the foreign matter entry determination unit 36.
[0025]
The foreign object entry determination unit 36 is a calculation unit. When digital signals are respectively output from the AD conversion circuits 35 and 35a, both digital signals are compared, and if both digital signals are the same, the photodiode 31 Since the current values I and Ia from both output terminals are I = Ia, the reflected light forms an image at the center of the light receiving surface of the photodiode 31 as set at the time of installation, and the light from the laser diode 25 is snocorail. It can be determined that the light is reflected by 16 road surfaces, and a normal signal is output to the drive circuit 41.
For example, a resin plate is inserted into the gap above the snorkel rail 16 and the light emitting diode provided at the tip of the board is blinked, so that the photodiode 31 outputs a false detection signal and increases the number of holding balls illegally. If unauthorized use of the pachinko machine is carried out, because the light of the laser diode 25 is reflected by the resin plate on the road surface of the slatted rail 16, the reflected light is offset from the center of the light receiving surface of the photodiode 31 imaging Then, the current values I and Ia output from both output terminals of the photodiode 31 become I ≠ Ia, and the digital signals output from the AD conversion circuits 35 and 35a to the foreign object entry determination unit 36 are different. In that case, the foreign object entry determination unit 36 outputs a foreign object entry signal to the drive circuit 41.
[0026]
The foreign substance entry signal of the drive circuit 41 is output to, for example, a host computer that is a central processing unit, and characters such as “foreign substance entry”, “game machine number”, and “date and time” can be displayed and output on a monitor or the like.
When the foreign matter entry determination unit 36 outputs a foreign matter entry signal to the drive circuit 41, the drive circuit 41 can supply the necessary current to the actuator 42, and the actuator 42 moves the foreign matter restraining member 45 downward, for example, to restrain the foreign matter. The member 45 and the snocorail 16 suppress foreign matter so that it cannot be removed from the snocorail 16 so that the player cannot take it away, and the clerk uses the foreign matter as material evidence of unauthorized use of the counting device. Can be mentioned. That is, it is possible to accurately detect the unauthorized use of the counting device, it is possible to cope quickly and accurately to unauthorized use of the counting device.
[0027]
In addition, in the said Example, although what used the photodiode 31 which is a position detection part was shown as what detects the entrance of a foreign material, it does not restrict to this, For example, a transducer is provided and a transducer is provided. measured configured to be able to time to receive from the transmitting sound waves, when foreign matter enters on the road surface of the slatted rail 16, the distance between the foreign substance and the transducer is a road of gridiron rail 16 handset Based on the fact that the time from when the transmitter / receiver transmits a sound wave to when it is received becomes shorter than when the foreign object is not inserted, becomes shorter than the distance from the waver 36 may output a foreign object entry signal.
Further, a transmission and reception units, when foreign matter enters on the road surface of the slatted rail 16, higher the frequency of the reflected wave compared to the frequency of the transmitted wave, by the difference between the reflected wave and the transmitted wave When a certain Doppler signal is extracted, and the Doppler signal is extracted, the foreign object entry determination unit 36 may output the foreign object entry signal.
Furthermore, although the thing using the pachinko ball was shown as a game medium, it is not limited to this, and it may be a game coin that flows down the alignment channel 16 .
[0028]
【The invention's effect】
According to the foreign matter detection device in the game medium counting device according to the present invention, when a foreign matter enters the alignment flow path of the counting device, the foreign matter entry determination unit outputs a foreign matter entry signal. In an unauthorized use of a pachinko machine that inserts a foreign object, blinks the light of the light emitting diode, and increases the number of balls illegally, such unauthorized use can be reliably detected and promptly dealt with, Occurrence of damage to the amusement hall can be prevented.
