PURPOSE: To reduce the number of parts and to improve maintaining convenience by reciprocatively rotatably locating a rotary member in a casing and shutting off a passage through protrusion and retraction of a pin in and from a ball passage through the reciprocating rotation, in a prize ball. feeding device for a PACHINKO (Japanese pin ball game) machine.
CONSTITUTION: Through excitation of a solenoid 7, a rotary bracket 3 is rotated in the direction of an arrow mark (a) around an axle 4. Through demagnetization of the solenoid 7, the rotary bracket 3 is rotated in the direction of an arrow mark (b) through the force of a tension spring 8. Through reciprocating rotation in the directions of the arrow marks (a) and (b) of the rotary bracket 3, pins 5 and 6 are alternately protruded in a passage 2 to shut off the passage 2, and the passage of a ball is blocked. This constitution reduces the number of parts, and decreases a space. Further, a wear part is reduced and maintenance, e.g. lubrication, is facilitated.
