(About illegal acts by radio waves)
Here, each ball detection such as the fixed start detection sensor 60, the gate sensor 61, the ball entry detection sensor 97, the first and second variable start detection sensors 66 and 67, the special prize detection sensor 73 and the normal prize detection sensor 74 described above. The sensor is a so-called inductive proximity switch, and in the pachinko machine 10 of the embodiment, the same sensor is adopted for all. Each of the sphere detection sensors 60, 61, 97, 66, 67, 73, and 74 has a basic configuration including a sensor body provided with an oscillation circuit and a sphere passage port through which a pachinko sphere can be passed. In the state where the ball detection sensors 60, 61, 97, 66, 67, 73 and 74 are not detecting the pachinko sphere (the state where the pachinko sphere is not passing through the ball passage opening), the oscillation circuit oscillates, It is set to output a level signal (hereinafter referred to as a high level signal). On the other hand, the ball detection sensors 60, 61, 97, 66, 67, 73, and 74 stop the oscillation of the oscillation circuit when the pachinko sphere is detected (while the pachinko sphere passes through the ball passage opening). Alternatively, the signal is attenuated and set to output a low level signal (hereinafter referred to as a low level signal). Then, the control means counts the pachinko ball by 1 when the output signal from the ball detection sensors 60, 61, 97, 66, 67, 73, 74 switches from the high level signal to the low level signal, and receives the prize ball.

A fraudulent act to be changed (hereinafter referred to as a fraudulent radio wave act) may be performed. In general, this fraudulent radio wave action is carried out by a fraudster concealing a radio wave generator obliquely below the game board 20 and moving to the lower part of the game board 20 where the composite ball entering parts 58, 59, the special prize winning part 52, etc. are provided. This is done by radiating radio waves from the radio wave generator. When the sphere detection sensors 60, 61, 97, 66, 67, 73, and 74 receive the radio waves radiated from the radio wave generator while the pachinko sphere passes through the sphere passage, the sphere detection sensors 60, 61, 97, 66, 67, 73 and 74 are erroneously detected as having intermittent oscillation. As a result, the sphere detection sensors 60, 61, 97, 66, 67, 73, and 74 repeatedly output a low level signal and a high level signal, and the control means switches each time the high level signal is switched to the low level signal. Pachinko balls will be counted. Then, the control means counts a plurality of prize balls even though one pachinko ball has passed through the ball passage opening, pays out a lot of prize balls, or judges per special figure or per ordinary figure. May be performed. Therefore, in the pachinko machine 10 of the embodiment, the first fraud detection device (fraud act detection means) 92 is installed in the sensor installation unit 94 in order to detect such an illegal radio wave action.
