Abstract
Abstract A cassette holder pivotally supported at its rear end and adapted to allow the insertion of cassettes at a set position within a cassette tape recorder. The cassette holder has a pivoted section capable of movement against the force of a spring so that the cassette holder can be rotated through a larger angle of inclination by removing it from a stopper which limits the angle of inclination, whereby a cassette can be directly placed within the tape recorder by inserting it below the cassette holder which has been rotated through the larger angle of inclination.
