のである。(Problems to be Solved by the Invention) According to the present invention, when a magnetic body is brought close to the four parts of two permanent magnets arranged so that their respective magnetic fields do not interfere with each other, depending on the manner in which the permanent magnets are arranged, A permanent magnet moves through a magnetic field,
Normally, a proximity switch installed in a position that is not affected by the magnetic force of these permanent magnets will operate due to the movement of the magnetic field, and even if a magnet with strong magnetic lines of force is brought close from the proximity switch side, the In addition to confirming that the proximity switch is activated, the act of bringing a magnet with strong lines of magnetic force close to it is considered a fraudulent act, and the number of times a magnetic detection object such as a pachinko ball passes through the official path is determined by the first proximity switch. When the magnet is brought close to commit fraud, the fraud detection circuit drives not only the first proximity switch but also the second proximity switch to detect that fraud is being committed. The purpose of this invention is to provide a configuration that allows sensing by driving the .
