  • Patent number: 5568340
    Abstract: A front loading cassette tape latching, loading and unloading device comprises a base seat, a cassette sliding plate, cassette clamping arms, cassette damping rollers, a cassette spring plate, cassette guide seats, a button sliding plate and a button sliding plate agraffe. When the cassette tape is being pushed into the machine, it will move the cassette sliding plate and trigger the button sliding plate agraffe to force the button sliding plate out, and further allow the cassette clamping arms to rotate. Rotation of the clamping arms forces the cassette clamping rollers to clamp the cassette and to latch the cassette tape on the guide seat. When removing the cassette, the button sliding plate is pushed to open the clamping rollers, and the cassette will spring out of the machine by the force of the cassette sliding plate. This compact cassette loading and unloading arrangement is easy to assemble and cost effective to produce.
