A power assist cassette loading device for pulling and loading a cassette automatically into a tape recorder. The device has a drive gear member adapted to be driven by a motor, a power assist member adapted to be driven by the drive gear member so as to sequentially effect the pulling of the cassette, loading of the cassette and advancing of a head plate overcoming respective biasing forces, and a power assist retainer member for retaining the power assist operation member. The power assist operation member is driven in the earlier half part of rotation of the drive gear member and is then retained by the retaining member. Then, in the later half part of the rotation of the drive gear member, the power assist operation member is released and made to sequentially effect the pulling of the cassette, loading of the cassette and the advancing of the head plate. Finally, the power assist operation member is retained again by the retainer member. |
