Abstract
The feeder includes a first sprocket provided in an insertion section, having engagement protrusions, engageable with engagement holes of a carrier tape, formed on only a part of the outer circumference, and a second sprocket arranged side by side with the first sprocket, on the supply section side of the first sprocket, having engagement protrusions formed over the entire circumference. A control device of the feeder restricts contact between the engagement protrusions of the first sprocket facing the carrier tape and the carrier tape after the engagement protrusions of the second sprocket disengage from the carrier tape in an unloading process of conveying the carrier tape to the insertion section side.
