2. Description of the Related Art In a conventional ball counting machine, a plurality of lanes for individually dividing the pachinko balls to be counted and transporting the pachinko balls to a calculation unit are provided, and the pachinko balls are rolled for each lane. Then, an optical sensor is installed in the calculation unit, a pachinko ball passing through each lane is detected, and the arithmetic means that has received the detection signal calculates and totals the number of pachinko balls detected by each optical sensor.

The optical sensor is a reflection type optical sensor which projects light onto a pachinko ball passing in front of the optical sensor and detects the pachinko ball by using reflected light reflected by the pachinko ball.
There is a transmitted light type optical sensor that detects the number of pachinko balls by using the transmitted light between the pachinko balls that pass in front of the light sensor that projects light.

[0009]

[Function] The pachinko ball passing through the lane is detected by the counting sensor. The ball passage monitoring sensor installed separately from the counting sensor detects a pachinko ball passing downstream of the counting sensor.

The number-of-balls signal detected and transmitted by the counting sensor and the number-of-balls signal detected and transmitted by the ball passage monitoring sensor are respectively transmitted to the calculating means.

After receiving the signal indicating that the pachinko ball has been detected from the counting sensor, the computing means receives the ball passage monitoring sensor within the time required for the pachinko ball to pass between the counting sensor and the ball passage monitoring sensor in a normal state. If it does not receive a signal indicating that a pachinko ball has passed, it issues an abnormal signal.

Embodiment An explanation will be given according to FIG. 1 and FIG. 2 showing a central sectional view of an embodiment of the present invention.

Reference numeral 11 is a ball counter. Ball counting machine 11
Counts the number of pachinko balls. Therefore, ball counting machine 1
An opening 12 for inserting a pachinko ball A to be counted is opened at 1.

Reference numeral 21 is a lane. Each lane 21
A plurality of pachinko balls to be thrown in at a time are installed in order to sort the pachinko balls, and each is divided by a lane partition wall so as to have a width slightly wider than the diameter of the pachinko balls A. Each lane 21 is installed with its tip inclined so that the pachinko balls A thrown into the slot 12 can move in the tip direction. A ball guide is installed on the bottom surface of each lane 21 in parallel with the lane partition, and guides the inserted pachinko ball A in the lane tip direction.

Reference numeral 31 is a counting sensor. The counting sensor 31 is installed in each lane 21 so as to detect the pachinko balls A passing in each lane. The counting sensor 31 emits light to a pachinko ball A passing in front of the counting sensor 31, and even if it is a reflection type in which the reflected light reflected by the pachinko ball A is detected to detect the pachinko ball A, the counting sensor 31 projects light. It may be a transmitted light type counting sensor 31 that detects the number of pachinko balls by detecting the transmitted light between the pachinko balls A passing in front of the sensor 31. In this embodiment, the counting sensor 31 is a reflection type photo sensor that receives the reflected light that reflects the light emitted from the light emitting diode by a phototransistor.

Reference numeral 41 is a ball passage monitoring sensor. The ball passing monitoring sensor 41 is installed in front of the ball drop box 42 at the tip of the lane 21 rather than the counting sensor 31, and is composed of a magnetic sensor or an optical sensor for detecting the material of the pachinko ball A. The ball passage monitoring sensor 41 is installed in each lane 21 or in some lanes 21.

Reference numeral 51 is a calculation means. The calculation means 51 is
It is connected to the counting sensor 31 and the ball passing monitoring sensor, and receives the ball number signal detected and transmitted by the counting sensor 31 and the ball number signal detected and transmitted by the ball passing monitoring sensor 41, respectively.

Next, the operation of the embodiment will be described. The pachinko ball A passing through each lane 21 is detected by the counting sensor 31. The ball passing monitoring sensor 41 installed separately from the counting sensor 31 detects a pachinko ball A passing in front of it.

The number-of-balls signal detected and transmitted by the counting sensor 31 and the number-of-balls signal detected and transmitted by the ball passing monitoring sensor 41 are respectively transmitted to the calculating means 51, and the calculating means 51 respectively calculates the number of balls.

After receiving the signal from the counting sensor indicating that the pachinko ball has been detected, the computing means 51 monitors the ball passage within the time required for the pachinko ball to pass between the counting sensor and the ball passage monitoring sensor at normal times. If the sensor does not receive a signal indicating that the pachinko ball is passing, it issues an abnormal signal. Therefore, in order to insert the reflector in front of the sensor and cause the sensor to make a false detection, the counting sensor 31
Not only that, a reflector that reaches the ball passing monitoring sensor 41 must be used, and if the reflector is still inserted in front of the sensor, the sensor can detect only one pachinko ball passing. Therefore, it is necessary for both sensors to detect the pachinko ball A with the same time lag as in the normal state. For that purpose, it is necessary to move the reflector in and out at the same speed as the time lag. However, such actuation is difficult in practice and anomalies due to cheating using the reflector are perceived.

[0021]

[Effect of the Invention] Therefore, according to this invention, it is possible to easily detect an abnormality in the ball counting machine.
