ABSTRACT:
The present invention is a protective cover opening mechanism for cassette loading and unloading apparatus of a digital compact cassette (DCC) or analog compact cassette (ACC). The apparatus consists of a sliding plate, a turning arm, a spline, and a stretching spring. The end surface of the sliding plate has an inclined plane with a concave channel at its bottom with an end part with the first pulling hook. There is a sliding slot on the sliding plate and the spline is fitted into this sliding slot. The spline shaft is attached to one end of the turning arm. The turning arm has a second pulling hook and there is a stretching spring connected between the first and second pulling hooks. The turning arm has a fixed pin, which when a DCC is inserted moves the fixed pin along the inclined plane of the sliding plate and while moving opens the protective cover. If an ACC is inserted, the fixed pin slides along the outer edge only and does not affect the ACC at all. When the DCC or ACC is ejected, it will return all the relevant moving elements to their original positions.
