The tray lock mechanism includes a magazine which accommodates trays each having an indentation; a sliding cover provided with trenches; and an elastic sheet provided between the magazine and the sliding cover, the elastic sheet also includes plural spring strips each having a hook part and an extrusion part. During the sliding of the sliding cover, it can select to unlock one or all disc trays or lock all disc trays. According to the tray lock mechanism of the present invention, it is possible to prevent trays from falling suddenly out from the magazine due to gravity and shaking when user draws the cartridge out from the disc device.
Claims12
A tray lock mechanism used in a multi-disc type optical disc device, in which the optical disc device includes a housing and a reading apparatus which is movably provided in the housing, the tray lock mechanism comprises:
- a magazine, on its outer surface a guiding track is provided;
- plural disc trays, which are accommodated in the magazine and each disc tray has an indentation;
- an elastic sheet, which is fixed on the magazine and includes plural spring strips each having a hook part and an extrusion part;
- and
- a sliding cover, which is movably fixed on the guiding track and is slidable along the guiding track, on its inner surface plural trenches are provided;
- wherein the indentation provided on the disc tray is used for engaging with the hook part on the spring strip and the trenches are used for accommodating the extrusion part on the spring strip;
- thereby when the sliding cover slides to a specific position, one or more of the extrusion parts is (are) accommodated in the trench(es) to allow the indentation of the disc tray disengaging from the hook part so that the corresponding disc tray(s) is(are) unlocked.
