  • Cassette holder opening system having a damper
    Patent number: 5483396
    Abstract: A cassette holder opening system comprises a damper, the damping force of which varies according to the opened angle of a cassette holder. In the damper, according to the variation of the opened angle of the cassette angle, a rolling member travels along a screw, so that the frictional force between the rolling member and a friction member, or the damping force varies. Accordingly, the cassette holder is completely opened and the opening operation of the cassette holder is steady, and furthermore the manufacturing cost is reduced and the fabrication thereof is easy due to the simple construction.
