ABSTRACT:
An automatic parts feeding apparatus of the invention is used to transfer a carrier tape for carrying parts thereon. The carrier tape has feed perforations formed in a predetermined pitch. The feeding apparatus is formed of a driving shaft rotated in one direction, a cam member fixed to the driving shaft and having a cam surface, a moving member abutting against the cam surface of the cam member, and a feed member attached to the moving member. The moving member is elevated, advanced, lowered and retreated through rotation of the cam member. The feed member engages at least one feed perforation of the carrier tape when the moving member is elevated by the first cam member, and it advances the carrier tape when the moving member is advanced. The feed member disengages from the feed perforation when the moving member is lowered. The carrier tape is moved by repeating the movements of the feed member.
