ABSTRACT:
A track changing mechanism for a cartridge-type tape player produces accurate vertical movement of the magnetic head under control of a stepped cam member by providing a holding member attached to the tape player chassis and extending vertically from it. A slidable plate is slidably engaged with the holding member and has a cam follower attached to it for adjusting the vertical position of the slidable plate in accordance with the rotational position of the cam member. The slidable plate also has a pair of projections extending from it, and the head of the player is mounted on a head mounting plate which is attached to the slidable plate. The head mounting plate includes a pair of notches in it for engagement with the projections to permit azimuth adjustments of the magnetic head.
