Description

  The present invention relates to a tape feeder that supplies an electronic component mounted on a component mounting apparatus and held on a carrier tape to a pickup position by a component transfer mechanism.

  A tape feeder is known as an electronic component supply device in a component mounting apparatus. This tape feeder supplies an electronic component to a pickup position by a transfer head of a component mounting mechanism by intermittently feeding a carrier tape holding the electronic component. In the vicinity of the pickup position, the carrier tape is pitch-fed by the tape feeding mechanism in a state where the carrier tape is covered and guided by the cover member along the tape running path provided in the main body of the tape feeder. The electronic component is picked up by the transfer head of the component mounting mechanism through the component take-out opening provided in the cover member at the pickup position.
