Abstract

PURPOSE:To provide an image recording/reproducing apparatus which never fails recording or reproduction due to miss-winding of a magnetic tape around a rotary drum resulting from loosening of the tape. CONSTITUTION:A reel base 9 which can be vertically extended or compressed and a means including a solenoid 10 for controlling such extension or compression of the reel base are comprised. Before a mechanism is loaded on a cassette holder, the reel base 9 which can be vertically extended or compressed is a little rotated to eliminate loosening of a magnetic tape. Thereafter, a cassette holder is loaded to the mechanism 2 under the condition that the magnetic tape 3 is not loosened.
