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. Due to this, a shock sound by the collision of the disc tray and the member on the casing side for restricting the pull-in position of the disc tray and the shock to the disc player by such a collision are eliminated, thereby raising the quality of the disc player.
