A one-directional clutch that only allows rotation in the forward direction, that is the cover tape pulling direction, is provided between, of two cover tape pulling gears, the lower side cover tape pulling gear and shaft thereof, such that reverse rotation of cover tape pulling gears is prevented by the one-directional clutch. For the engaging portion of the one-directional clutch and cover tape pulling gear, the friction of the engaging portion of the one-directional clutch and the cover tape pulling gear is adjusted such that the cover tape pulling gear slip rotates in the reverse direction when a specified rotational force or greater in the reverse direction that is greater than the force required to peel the cover tape is applied to the cover tape pulling gear.
