PURPOSE: To provide a silent Pachinko (Japanese pinball game) shooting device of simple structure, by comprising a power supply means for supplying electric current to plural driving coils wound adjacently to a cylindrical body through which the Pachinko balls can be passed, while shifting a phase. CONSTITUTION: Two driving coils 3, 4 are dividually wound adjacently to a lower part of a cylindrical body 2 through which the Pachinko balls 1 can be passed. The voltage of an AC power source 5 is directly supplied to the driving coil 3, and the voltage of the AC power source 5 is supplied to the driving coil 4 through a capacitor for phase splitting 6. The winding directions of the coil 3 and the coil 4 are same as each other, the electric current is flowed to the coils 3, 4 in a condition that the phases are alternately shifted, and the shifting magnetic field is generated from an inlet 2a to an outlet 2b of the cylindrical body 2. When the Pachinko ball 1 of ferromagnetic body is inserted from the inlet 2a of the cylindrical body 2, the Pachinko ball 1 is accelerated by the thrust of the shifting magnetic field by the coils 3, 4, to be short from the outlet 2b. That is, the driving coils 3, 4 form a stator of an induction-type linear motor, and the Pachinko ball 1 itself becomes a mover to be directly advanced and shot. |
