ABSTRACT:
A casette tape recorder, wherein, when a cassette-ejecting engagement lever is pressed, a movable chassis is rotated from the lifted position to the lowered position to be engaged with a rotatable engagement cam, thereby previously accumulating the urging force of a tension spring stretched between the fixed and movable chassis. An engagement cam is rotated clockwise by a release lever which is rotated clockwise by a cassette inserted into the tape recorder, thereby releasing the movable chassis from the engagement cam, the movable chassis is lifted by the accumulated urging force of the tension spring. The urging force of the tension spring is not accumulated at the insertion of the cassette into the tape recorder, but at the ejection of the cassette. The inserted casette rotates the release lever only for the disengagement of the movable chassis from the engagement cam. The cassette can be inserted into the tape recorder only with a slight force. When the engagement lever is pressed, the engagement cam is rotated counterclockwise by the urging force of a torsion coil spring, thereby causing the release lever to be rotated counterclockwise for the ejection of the cassette.
