  • Patent number: 5555227
    Abstract: A disc recording/reproducing apparatus includes a recording/reproducing section, a disc tray, a driving mechanism, a rotary table, a lock mechanism for the disc tray and an oscillation suppression mechanism. The recording/reproducing mechanism is provided in a main body of the apparatus for recording/reproducing information signals on or from the disc. The disc tray may be moved between a position facing the recording/reproducing section in the main body of the apparatus and an unloading position outside of the main body of the apparatus. The driving mechanism causes the disc tray to be moved between the loading position and the unloading position. The rotary table is rotatably mounted on the disc tray and has plural disc-setting sections extending radially from the center of rotation. The rotary table may be rotated relative to the disc tray for selectively locating one of the plural disc setting sections at a position facing the recording/reproducing section.

  • Patent number: 5123005
    Abstract: A loading mechanism of a disc tray onto which recording medium discs such as compact discs, laser discs, or the like are set and which moves between a pull-out position at which the disc tray was pulled out of an outer casing and a pull-in position at which the disc tray was pulled into the outer casing. The engagement between the loading gear and the rack of the disc tray is released just before the pull-in operation of the disc tray is completed and, at the same time, a cam portion formed on the loading gear comes into engagement with the abutted portion of the disc tray, thereby allowing the disc tray to be subsequently pulled in by the pressing motion of the cam portion to the abutted portion. Thus, the pull-in speed of the disc tray can be reduced just before the completion of the pull-in operation of the disc tray and a shock which occurs upon completion of the pull-in operation of the disc tray can be reduced.
