Description

  The present invention relates to a tape feeder and a component mounting apparatus that intermittently advance a component supply tape drawn from a tape reel and continuously supply components stored in the component supply tape to a component supply position. .

  In recent years, component mounting apparatuses have been required to improve area productivity, and in order to increase the number of tape feeders that supply parts to the component mounting apparatus, it is desired to reduce the thickness of the tape feeder.

  Here, the tape feeder advances the component supply tape drawn out from the tape reel and guided into the feeder main body by the intermittent rotation of the sprocket included in the feeder main body attached to a predetermined location (feeder base) of the component mounting apparatus. Thus, the components stored in the component supply tape are continuously supplied to the component supply position of the feeder main body.

  Some tape feeders have a reel holding part for holding the tape reel integrated with the feeder main body. If the tape feeder is made thin by reducing the width direction dimension of such a tape feeder, the feeder main body In addition to reducing the thickness of the part, it is also required to reduce the thickness of the reel holding part.

  In such a tape feeder in which the reel holding portion is integrated, the reel holding portion (that is, the tape reel) can be selectively positioned at one of two upper and lower positions set with respect to the feeder main body portion. (For example, Patent Document 1). With such a configuration, the reel holding portions of the adjacent tape feeders are positioned so that the top and bottom are staggered, the interference of the adjacent tape feeders is prevented, and the tape feeder is thinned.
