Cartridge reproducing device with built-in disk

Abstract

Abstract PURPOSE:To always secure the vibrationproof characteristic of the servo driving mechanism of an objective lens against external vibration except a time of reproduction, by separating a rack member from a rack part by the motion of a cartridge holder. CONSTITUTION:A fixing means to fix the objective lens 58, and a holding member (pickup body 7) with holds the servo driving mechanism of the objective lens, and moves along a disk recording plane, on a housing, is provided with the rack part provided at the pickup body 7 along the moving direction of the holding member, the rack member provided along the moving direction in such a way that it can engage and disengage with the rack part freely, and a pressing means which presses the rack member to the rack part, and the rack member is separated from the rack part by the motion of the cartridge holder 131. Therefore, the pickup body 7 is always fixed on the housing 78 at a time except the time of reproduction when the cartridge holder 131 is operated, thereby, the vibrationproof characteristic of the servo driving mechanism can be secured against the external vibration.
