PROBLEM TO BE SOLVED: To reduce feed resistance of a tape during mounting of components in a tape feeder having a second sprocket on the upstream side in addition to a first sprocket which performs pitch feed of the tape during mounting of components.SOLUTION: A one-way clutch is arranged in a rotating force transmission part by an intermediate gear 4 arranged between a second sprocket 6 and second rotation driving means 8. This one-way clutch is arranged so that rotating force is transmitted when the second rotation driving means 8 is driven to rotate the intermediate gear 4 and the rotating force is prevented from being transmitted when the second sprocket 6 is dependently rotated by engagement with a hole part of the tape T while stopping the second rotation driving means 8. 【課題】部品実装時にテープをピッチ送りする第１スプロケットに加え、その上流側に第２スプロケットを有するテープフィーダにおいて、部品実装時のテープの送り抵抗を低減すること。【解決手段】第２スプロケット６と第２回転駆動手段８との間に配置された中間ギヤ４による回転力伝達部にワンウェイクラッチを配置した。このワンウェイクラッチは、第２回転駆動手段８を駆動させて中間ギヤ４を回転させるときには回転力を伝達し、第２回転駆動手段８が停止した状態で第２スプロケット６がテープＴの孔部との噛み合いによって従動回転するときは回転力を伝達しないように配置した。【選択図】図１
