Abstract

PURPOSE:To eliminate the need to unset a magnetic tape with hands when the tape is cleaned, by providing a cleaning member and a tape shifter to a rotor which is set eccentrically to a cylinder. CONSTITUTION:A rotor 12 is set eccentrically to the rotational center of a cylinder 5, and a rotation transmitter 13 is set in contact with the outer surface of the rotor 12 to transmit the rotation to the rotor 12. The transmitter 13 interlocks a driver 14. A tape shifter 15 is provided to the rotor 12 to shift a magnetic tape 1 out of the cylinder 5. The shifter 15 contains a cleaning member 16 which is in contact with the cylinder 5 as well as magnetic heads 9 and 10. When the tape contact surfaces of the heads 9 and 10 plus the cylinder 5 are cleaned, the rotor 12 is rotated to rotate and shift the member 16. Thus contact is secured between the member 16 and the heads 9 and 10, respectively.
