Abstract:
A feeder for feeding electronic chip components, comprising:a hopper for retaining a plurality of electronic chip components, said hopper having a discharge opening formed in the bottom thereof; an aligning path forming member having a tubular aligning path for receiving the electronic chip components in an aligned state, said aligning path forming member located within said discharge opening; a mechanism for reciprocating said aligning path forming member in an axial direction of said discharge opening over a stroke range having an upper limit, wherein said upper limit is the upper projection height of said aligning path forming member, and wherein movement of said aligning path forming member agitates the electronic chip components, causing the electronic chip components to enter said tubular aligning path; and a mechanism for varying said upper limit of said stroke range of said aligning path forming member, such that said upper projection height of said aligning path forming member can be varied.
