PURPOSE: To convey the total number of goods in regular postures by discriminating postures of parts supplied from a parts feeder on the way of conveyance and correcting them into regular ones by posture-correction means for conveying as they are even if they are irregular.

CONSTITUTION: Goods supplied from a parts feeder 1 are pooled in an accumulator shoot 3, and sent out through a gate 4 one by one. When they first pass a photoconductive cell 6, they are discriminated in their lengthwise directions; when they are regular, they are made to pass a shutter 7 and a rotary actuator 8, and when found irregular, corrected in their directions by 180° by the operation of the actuator 8. Then, goods are sent to a crosswise-direction discriminating part of photoconductive cells 10a and 10b for crosswise disdrimination, and those found to be irregular are reversed by 180° by a shutter 11 and an actuator 12 and conveyed. Thus, goods are sent into a chute 13 with regular postures.
