ABSTRACT:
A front-loading type disk player, such as a video or compact disk player, having an improved front loading mechanism which absorbs any play or backlash that occurs during the movement of the carriage so that the carriage is accurately controlled in position as it moves in and out of the housing of the player. Support members for the chassis have a stopper with which the carriage comes into contact when the disk reaches a predetermined playing or recording position. An energizing force is applied during the time an accelerating mechanism drives the carriage in the direction of the accommodation position inside the housing, continuing for a short time after the carriage contacts the stopper. The excess force is absorbed by urging the carriage against the stopper.
