Abstract

PURPOSE:To separate accurately articles to be conveyed and prevent dislocation and fall by providing a compressed air exhaust nozzle at the stepped part formed in the specified position of a guide rail. CONSTITUTION:When the compressed air is sprayed onto the rear part of a semiconductor device 1a in the direction C from a compressed air exhaust nozzle 13, the semiconductor device 1a is separated from a successively adjoining semiconductor device 1b and sent out in the direction B. At this separation operating time, the head semiconductor 1a on which the compressed air is sprayed can be separated smoothly even in the vertically overlapping state of the protrusions of the adjoining semiconductor devices 1a, 1b. In this case, the successively adjoining semiconductor device 1b is inhibited to move by a lowered setting claw 4. When the locking claw 4 goes up after the head semiconductor device 1a being separated from the successive semiconductor device 1b and sent out in the direction of conveyance, the successive semiconductor device 1b is dropped onto the stepped part 12a of a first guide rail 12, and the above operation is repeated.
