In the figure, 1 is a pachinko ball counter, 2 is a pachinko ball passage, and 3 is a pachinko ball detector. When a large number of pachinko balls are put into the pachinko ball counting machine 1, the put-in pachinko balls are temporarily stored in the upper part of the pachinko ball counting machine 1 and discharged from the pachinko ball counting machine 1 through the passage 2 one by one.

The conventional pachinko ball counting machine has made it possible to increase the pachinko ball count value by an illegal method other than a pachinko ball. As an illegal method, for example, the following method is assumed. A string is attached to the pachinko ball, and after the pachinko ball has passed through the pachinko ball detection unit 3, the pachinko ball is pulled back, and such an operation is repeatedly performed to increase the pachinko ball count value. The rotating body on the cylinder is brought close to the pachinko ball detection unit 3, and the striped or spiral pattern attached to the rotating body causes
The pachinko balls appear as if they passed continuously. A light emitting diode is brought close to the pachinko ball detection unit 3 to artificially create a light situation when the pachinko ball passes. A cylinder having a reflecting portion is rotated near the pachinko ball detection unit 3 to operate the pachinko ball detection unit 3 as if the pachinko ball passed.

1 is a diagram showing a configuration example of an electric circuit of a pachinko ball counter. In the figure, reference numeral 4 indicates a counting abnormality detection unit, and A to E indicate detection elements, respectively. Each of the detection elements A, B, ..., E has a driver and a sensor. The sensor output of the detection element A is input to the input terminal SEN-A of the counting abnormality detection unit 4, and the sensor output of the detection element B is input to the input terminal SEN-B of the counting abnormality detection unit 4. The following is as illustrated. Further, the driver signal of the detection element A is output from the output terminal DR-A of the counting abnormality detection unit 4, and the driver signal of the detection element B is output from the counting abnormality detection unit 4.
Is output from the output terminal DR-B. The following is as illustrated. The counting abnormality detection unit 4 includes detection elements A, B, ..., E.
The sensor output of is acquired, and a count output or an abnormal output is generated based on the acquired sensor output.

FIG. 2 shows the arrangement of the detection elements when viewed from the side, and FIG. 3 shows the arrangement of the detection elements when viewed from the top. In the figure, 5 indicates a pachinko ball. As can be seen from FIG. 2, the detection elements A, B, C are arranged on the upper side of the pachinko ball passage 2, and the detection elements D, E are arranged on the lower side of the pachinko ball passage 2. The pachinko balls 5 flow from the upper right to the lower left. As can be seen from FIG. 3, the detection elements A, B, C
Are arranged so as to form a V shape with respect to the passing direction of the pachinko balls 5. In the illustrated example, the detection elements A and C are arranged so as to be present on the same pachinko ball passage direction line, and the detection element B is present on the pachinko ball passage direction line below the detection elements A and C. Are arranged as follows.

FIG. 4 is a diagram showing a circuit configuration example of the detection elements A, B, C, D, and E. In the figure, 7 is a light emitting diode, 8 is a phototransistor, and 9 and 10 are inverting circuits. The detection elements A, B, C, D and E have the same configuration. The light emitting diode 7 lights up when the DR signal (drive signal) is 1 (high level), and 0
Turns off when (low level). Photo transistor 8
A current flows when the light from the light emitting diode 7 is received, and the level of the SENCE signal (sensor signal) becomes zero. Further, when no light is incident on the photo transistor 8 or when the light emitting diode 7 is not emitting light, no current flows, and the level of the SENCE signal becomes 1.

Each of the detecting elements A, B, C, D and E is of a reflective type. For example, when a pachinko ball exists below the detection element A, the light emitted from the light emitting diode 7 of the detection element A is reflected on the surface of the pachinko ball, and the reflected light is incident on the phototransistor 8 of the detection element A, The SENCE signal from the detection element A becomes 0.

FIG. 5 shows the detection elements A, B, ..., E when the pachinko balls pass near the detection elements A, B, ..., E under the condition that the drive signals of the detection elements A, B ,. It is a figure which shows the waveform of the sensor signal of B, ..., E. In the figure, Ta is the time difference between the fall of the sensor signal of the detection element A and the fall of the sensor signal of the detection element B, and Tb is the fall of the sensor signal of the detection element B and the sensor signal of the detection element C. The time difference between the falling edge and the falling edge, Tc, represents the time difference between the falling edge of the sensor signal of the detecting element D and the falling edge of the sensor signal of the detecting element E, respectively.

In accordance with the flow of the pachinko balls, the detection signals of the pachinko balls are sequentially output from the detection element A existing on the upstream side of the flow. The time difference between the sensor signals from the detection elements A, B, C, D, and E is proportional to the distance in the flow direction of the pachinko balls at the position where each detection element is arranged, and is inversely proportional to the moving speed of the pachinko balls. Normally, the moving speed of the pachinko ball on each detection element is
There is no large variation. Further, the movement speed of the pachinko balls tends to increase to some extent at the position of the detection element on the downstream side, but the increase of the movement speed can be ignored for a short distance between the detection elements.

From the above, in the case of a normal pachinko ball flow, Ta = Tb (1) holds and Ta ≧ 0, Tb ≧ 0, Tc ≧ 0 (2) holds.

Next, a method will be described in which a string is attached to a pachinko ball, the same pachinko ball is moved back and forth on the side of the detection element many times, and an improper attempt to increase the count value of the pachinko ball is detected. FIG. 6 is a diagram showing a timing waveform when a string is attached to a pachinko ball and the same pachinko ball is moved forward and backward. The waveform when the pachinko ball passes by the detection elements A, B, C, D, and E while moving forward due to gravity is the same as the waveform in the normal state (see FIG. 5).

However, the waveform when the string attached to the pachinko ball is pulled and the pachinko ball is moved backward while passing through the side of the detection elements A, B, C, D, and E is the waveform at the normal time. Is different from That is, while moving the pachinko ball backward, the detecting elements A, B, C, D,
When passing through the side of E, the detection element C first detects a pachinko ball, then the detection element B detects a pachinko ball,
Next, the detection element A detects a pachinko ball. Detector element D,
Regarding E, first, the detection element E detects a pachinko ball,
Next, the detection element D detects a pachinko ball.

Thus, the detection elements A, B, C, D, E
Check whether the time series of the pachinko ball detection timing of is different from the time series of the pachinko ball detection timing of the detection elements A, B, C, D, E in the normal time, and if they are different, it is determined to be illegal or counted once. It is possible to prevent fraud by subtracting the number.

FIG. 7 is a diagram showing an example of a striped rotary member used when making an illegal act. In the figure, 11 is a motor and 12 is a striped rotor. The motor 11 and the striped rotor 12 are connected by a connecting rod such as a wire. The striped rotator 12 has a cylindrical shape, and a portion that absorbs light and a portion that reflects light are alternately provided on the cylindrical surface to form a striped shape.

FIG. 8 shows a timing waveform in the striped rotor. The striped type rotating body 12 is inserted into the pachinko ball passage and positioned at the positions of the detection elements A, B, C, D and E, and the motor 11
When rotated by, the waveforms of the output signals from the detection elements A, B, C, D and E are as shown in FIG. Although the waveform on the left side and the waveform on the right side of FIG. 8 are different, for example, when the striped rotor is rotated in the clockwise direction (the direction from the motor to the striped rotor is positive), the left waveform is rotated. And when rotated counterclockwise, the waveform on the right side is obtained.

The output signals of the detection elements A, B, and C are not output in order regardless of the waveform on the left side or the waveform on the right side. That is, in the waveform on the left side, the falling timing of the output signal of the detection element A and the falling timing of the output signal of the detection element C are the same, but the falling timing of the output signal of the detection element B is later than this. There is. In the waveform on the right side, the falling timing of the output signal of the detection element A and the falling timing of the output signal of the detection element C are the same, but the falling timing of the output signal of the detection element B is ahead of this. When this timing shift is detected, an irregularity can be prevented by outputting an abnormality or not counting.

FIG. 9 is a diagram showing an example of a spiral type rotating body used when making an illegal act. In the figure, 13 is a motor and 14 is a spiral type rotating body. The motor 13 and the spiral type rotating body 14 are connected by a connecting rod such as a wire. The spiral type rotating body 14 has a cylindrical shape, and a portion that absorbs light and a portion that reflects light are attached to the cylindrical surface in a spiral shape.

FIG. 10 shows a timing waveform in the spiral type rotating body. When the spiral type rotating body 14 is inserted into the pachinko ball passage, positioned at the positions of the detection elements A, B, C, D and E, and rotated by the motor 13, the detection elements A, B,
The waveforms of the output signals from C, D and E are as shown in FIG. Although the waveform on the left side and the waveform on the right side of FIG. 10 are different, for example, when the spiral type rotating body is rotated clockwise, the waveform becomes the left side waveform, and when it is rotated counterclockwise, the waveform becomes the right side waveform.

In both the left-sided waveform and the right-sided waveform, the output signals of the detection elements A, B, and C are output in order, but the time difference varies greatly. That is, in the waveform on the left side, the time difference Tb is significantly larger than the time difference Ta. The time difference Ta is the time difference between the fall timing of the output signal of the detection element A and the fall timing of the output signal of the detection element B, and the time difference Tb is the fall timing of the output signal of the detection element B and the output of the detection element C. It is the time difference between the falling timings of the signals. In the right waveform, the time difference Ta becomes significantly larger than the time difference Tb.
When such a time difference variation is detected, an irregularity can be prevented by outputting an abnormality or not counting.

FIG. 11 is a view showing an example of a light emitting diode type illegal tool. In the figure, 15 is a light emitting diode, 16 is a disk, and 17 is an operating rod.
The light emitting diode 15 is installed on the circumferential surface of the disk 16.
An operating rod 17 is attached to the disc 16. Disk 1
6 is inserted in the pachinko ball passage, and each of the five light emitting diodes 15 installed on the cylindrical surface of the disk 16 is made to face the detection elements A, B, C, D, E, and the blinking of each light emitting diode 15 is turned on. By controlling it, it becomes possible to pretend that a pachinko ball has passed.

When the light emitting diode of the detection element is always made to emit light, it becomes possible to make a fraud by using the light emitting diode type fraudulent tool shown in FIG. In order to prevent fraud, the light emitting diode 7 (see FIG. 4) of the detection element is made to emit light intermittently. Then, the light emitting diode 15 on the disk 16 must emit light in synchronization with the light emitting timing of the light emitting diode 7 of the detection element.

That is, in FIG. 12, the falling timing of the SENCE signal (output signal of the detection element) is delayed from the rising timing of the DR signal with respect to the emission timing of the DR signal (drive signal of the light emitting diode 7). This delay is determined by the physical condition of the detection element. E-TIME considers this property and SENC
This is to create a timing at which the E signal can be output.
That is, within the period when the E-TIME signal is high level, SE
When the NCE signal becomes low level, an abnormality is output.

In consideration of the intermittent light emission of the detection element, a light receiving element is provided in the light emitting diode type illegal tool of FIG. 11, and the light emission of the light emitting diode type illegal tool can be synchronized with the light emission of the light emitting diode of the detection element. Even if the circuit is made possible, the delay time is required to be doubled in the light emitting diode type illegal tool circuit as compared with the normal case. Due to the timing restricted by E-TIME, the circuit incorporating this light reception / emission cannot be timed, and an incorrect counting can be prevented. The fact that the light emitting diode of the detection element does not always emit light means that the detection elements A, B, C, and
It has a role of preventing mutual interference between the D and E light emitting elements.

In FIG. 14A, the time difference between the fall timing of the output signal D of the detection element D and the fall timing of the output signal of the detection element E is -Tc.
In (b), the time difference between the fall timing of the output signal D of the detection element D and the fall timing of the output signal of the detection element E is Tc. That is, in FIG. 14 (a),
After the output signal of the detection element E falls, the detection element D
The output signal of is falling. If this is detected,
It can be considered that there was dishonesty.
