成されていることを特徴とするモード切換装置。[Claims for Utility Model Registration] A head base that is equipped with a magnetic head and moves in a direction in which the magnetic head comes into contact with and separates from a magnetic tape, and a spring that biases the head base in a direction in which the magnetic head separates from the magnetic tape. In the tape player, the head base is driven to press against a spring by a switching cam rotationally driven by a motor, the switching cam having a position where the magnetic head contacts the magnetic tape. A driving plane is formed that stably contacts the head base at the position where the magnetic head is pressed, and a stop plane that stably contacts the head base at the position where the magnetic head leaves the magnetic tape immediately after this driving plane is separated from the head base. A mode switching device characterized by:
