Tape guide drive mechanism for magnetic recording-reproduction device in which the tapes are driven by a slide member driven directly by cam

摘要

A chassis mounting thereon a drive slide for rotating tape guides arranged within a cassette in a tape withdrawing direction, and a cam gear for driving the drive slide. The cam gear and the drive slide provide a linear motion mechanism for connecting the drive slide with the cam gear by the rotation of the cam gear through a predetermined angle and disengaging the drive slide from the cam gear by the rotation of the cam gear through more than the predetermined angle. A lock mechanism is provided for connecting the drive slide with the chassis when the drive slide is out of connection with the cam gear and disengaging the drive slide from the chassis when the drive slide is connected with the cam gear.
