Abstract
An optical pickup device with elastic member, the device comprises a driver, a gear, a rack, an optical head, a guide bar and an elastic member. The gear associated with the driver is rotated by it. The rack, whose back has at least a first fixed support, meshes and interlocks with the gear. One end of the optical head has at least a second fixed support with which the first fixed support connects through the guide bar so the rack and the optical head can interlock each other. The elastic member of the invention located on the optical head shores against the rack to provide a vertical elasticity and a parallel elasticity to the rack axle and reduce the back clearance between the gear and the rack, and the clearance between the rack and the optical head.
