Abstract: PURPOSE:To prevent the occurrence of so-called head clogging by effectively cleaning a recording and reproducing swivel head moving on a circular locus and further to restore the swivel head to the normal state, even if magnetic powder, etc., are accumulated in the head gap of the swivel head, etc., to bring about the head clogging state. CONSTITUTION:A freely rotating cleaning roller 41 is supported by the rotating end of a rotating arm 30, which is supported by a mechanical chassis 2 in the manner of freely rotating in the horizontal direction, and the cleaning roller has a structure, in which many plate-shaped tape pieces 43, 43... are radially secured around a rotating shaft 42. In a state where a rotating drum 4 rotates, then, cleaning is performed when the rotating arm is rotated so that the tape pieces of the cleaning roller are brought into contact with recording and reproducing swivel heads 6, 6,... moving on a circular locus.
