PURPOSE:To arrange a plurality of pulverulent bodies in order on the same surface to enclose the whole device in a narrow space by reciprocating a carrier for receiving the pulverulent bodies supplied from a hopper in a constant cycle by a solenoid to drop the pulverulent bodies onto an inclined surface forming a path at a certain time intervals. CONSTITUTION:On a carrier 2 for pulverulent bodies 8 supplied from a hopper 1 is mounted a plunger 4 of a solenoid 3 to which pulsating current or the like obtained from the half-wave rectification of AC is supplied to reciprocate the carrier 2 in the same cycle as this pulsating current. Thus, the pulverulent bodies are respectively vibrated and dropped onto an inclined surface 6 from an opening in the carrier 2. Also, the inclined surface 6 is provided with wire rods 7 crossing each other to form paths 10 along which the pulverulent bodies 8 are dropped. Thus, a plurality of pulverulent bodies 8 can be arranged in order on the same surface and the whole device can be enclose in a narrow space when defectives are segregated from a plurality of pulverulent bodies 8 and subsequently worked. |
