A challenge to be met by the present invention is to feed a carrier tape with superior positional accuracy by means of a simple, inexpensive configuration, thereby enhancing punching accuracy of a component and implementing highly reliable component mounting. A carrier tape feeder that feeds a carrier tape (11), to thus feed and position a component (10) to be punched next to a component pickup section (23) is built from a positioning feed roller (25) including sprocket wheels (61) that feed the carrier tape (11) by causing sprocket holes (13) formed in the carrier tape (11) to engage with teeth (62) and rotating the sprocket wheels and a support wheel section (63) around which there is wound at least a neighborhood of the sprocket holes (13) of the carrier tape (11) in a widthwise direction thereof, to thus support the carrier tape 811); and a rotation device (65) that rotationally drives the positioning feed roller (25). A diameter of a root circle (64) of the sprocket wheel (61) is set smaller than an outside diameter of the support wheel section (63). |
