ング機構。[Claims for Utility Model Registration] (1) A rotating cylinder equipped with a plurality of magnetic heads, a tape loading completion position where a magnetic tape is pulled out from a tape cassette and wound around the rotating cylinder at a predetermined angle, and a magnetic tape from the rotating cylinder. A tape unloading guide that moves between a tape unloading completion position where the tape is removed and stored in the tape cassette, a driven cam gear that drives the tape unloading guide, a cleaning roller at one end and a follower pin at the other end. A rotating lever is biased in one direction, and the following pin follows the cam portion of the driven cam gear during the movement of the tape pull-out guide to bring the cleaning roller into contact with the rotating cylinder for a predetermined period of time. Features an automatic head cleaning mechanism. (2) The automatic head cleaning mechanism according to claim 1, wherein an instantaneous tape cleaning roller is brought into contact with the rotary cylinder when the tape traveling operation mode is shifted in accordance with the rotation of the driven cam gear.
