Abstract: The present invention is intended to feed components stably and speedily in a component feed apparatus whereby components stored in the form of a taped component, while being transferred along a component feed guide, are sequentially supplied to a predetermined position to be mounted to a printed board. In order to accomplish the object, a magnet is set in the vicinity of a slit of a component feed guide at which a covering tape is separated from the taped component. The magnet magnetically attracts the component, to thereby prevent the component from being forcibly dragged together with the covering tape when the covering tape is separated. Quick and stable supply of the component can be accordingly ensured.
