Abstract
A cleaning structure for removing dust is constituted of a guiding member having a sliding surface for guiding run of a tape, and a vacuum pressure supply source for making a vacuum pressure effect on a suction space provided inside the guiding member and so on. At the sliding surface of the guiding member, a suction port for making the suction space communicate with an external space is formed, and the opening edge of the suction port on the downstream side in the tape running direction is served as a first dust removal portion for removing dust on the tape surface. The guiding member has a guiding wall having a contact surface which guides at least one tape edge of a tape, and the contact surface is served as a second dust removal portion for removing dust adhering to the tape edge.
