ABSTRACT:
A novel structure concerning the head base drive mechanism in a cassette tape player. In order to drive the head base from the stop position to the playback position, a first cam provided on a cam gear is used to actuate the head base in cooperation with the capstan gear. For driving the head base from the playback position to the stop position, a leaf spring attached to the chassis is used. In order to assist the leaf spring, a second cam is provided on the head base. This second cam is located on the head base playback side of the cam follower and has a profile increasing closer to a center of the cam gear as said cam gear rotates to actuate the drive pin toward the stop position of the head base.
