<p>PURPOSE:To easily remove dust powder sticking to a tape by eliminating static electricity charged on the tape when the tape is traveled to pass an electrostatic eliminating means, removing the powder from the tape with a tape contacting means and performing forced exhaust with an exhaust means. CONSTITUTION:The magnetic tape 1 is traveled from the upward left to the upward right after contacting its back side with a roller 4 as the tape contacting means. One pair of electrodes 2 opposite to each other with the magnetic tape 1 between them under noncontact is provided as the electrostatic eliminating means on this side of the roller 4, and when the magnetic tape 1 is passed through between them, its charged static electricity is eliminated. Then, the roller 4 is housed in a suction room 5, and this suction room 5 is connected with exhaust ducts 12 and 12 and further connected to an exhaust blower 9 as the exhaust means, so that removed magnetic powder and dust, etc., from the magnetic tape 1 are exhausted with air. By this method, the powder to stick to the tape effectively is removed.</p> |
