ABSTRACT:
A carrier tape for carrying electronic components thereon forward to a sucking position is formed therein with a plurality of recesses for accommodating the electronic components, respectively, and advanced intermittently with the electronic components contained in the recesses. A suppressor is arranged at a location backward of the sucking position for preventing the electronic components from jumping out of the recesses. A shutter is arranged for sliding contact with the carrier tape such that the shutter is capable of being moved forward and backward along length of the carrier tape to open and close each of the recesses in the sucking position. The shutter has a forward end portion larger in width than a width of the each of the recesses and is formed by a plate spring extending obliquely toward the carrier tape for suppressing the carrier tape. The suppressor has a shutter-receiving portion extending toward the sucking position for receiving the shutter when the shutter is moved backward to open the each of the recesses in the sucking position. Alternatively, the shutter comprises a sliding contact portion for sliding contact with an upper surface of the carrier tape, a holding portion for holding the sliding contact portion, and a spring interposed between the sliding contact portion and the holding portion to urge the sliding contact portion against the carrier tape.
