Patent ID: 7930819

Claim:
A component supply unit comprising: a feed-out device adapted to intermittently feed out a component supply tape toward a component supply position provided on a feed path extending in a given direction, the component supply tape including a carrier tape having components stored therein at constant intervals, and a cover tape attached to the carrier tape to prevent jump-out of the stored components; a guide device set up along the feed path and adapted to guide the component supply tape from widthwisely opposite sides thereof to keep a feed posture of the component supply tape in a normal posture; a turnaround portion set up above the feed path; and a take-in device adapted to take in the cover tape turned through the turnaround portion to peel off the cover tape from the carrier tape, during a course of feeding the component supply tape, wherein the guide device includes a downstream guide section located downstream of the component supply position in a tape feed direction and adapted to guide the component supply tape, and an upstream guide section located upstream of the component supply position in the tape feed direction and adapted to guide the component supply tape, the downstream guide section and the upstream guide section being formed integrally; the downstream guide section includes a pair of first guide walls located on the widthwisely opposite sides of the component supply tape; a bottom wall connecting respective lower portions of the pair of first guide walls; and an open surface formed as an opening in a top surface between the pair of first guide walls and formed in a continuous manner in the tape feed direction, whereby the cover tape can be taken in and out relative to the downstream guide section through the open surface; and the upstream guide section includes a pair of second guide walls located on the widthwisely opposite sides of the component supply tape; a ceiling wall connecting respective upper portions of the second guide walls; and an opening formed in a bottom surface between the pair of second guide walls.
