Electric-component feeder

摘要

An electric-component feeder (92) for feeding a carrier tape (148) carrying electric components (78) at a predetermined component-carry pitch, at a tape-feed pitch equal to a quotient obtained by dividing the component-carry pitch by an integral number, and thereby supplying the electric components, one by one, the feeder including a main frame (100) including a tape guide (158) which guides the carrier tape in a lengthwise direction thereof; a cam (234) which has a cam surface (236) and which is provided on the main frame such that the cam surface is movable relative to the main frame; a cam drive device (245) which is supported by the main frame and which drives the cam and thereby moves the cam surface relative to the main frame; a cam follower (230) which is supported by the main frame and which follows the cam surface while being moved by the cam surface being moved by the cam drive device; and a motion converting device (192, 196, 200, 202) which is supported by the main frame and which converts the motion of the cam follower into the feeding of the carrier tape at the tape-feed pitch along the tape guide of the main frame.
