Abstract: A barrier mechanism, which is often utilized in a disk changer device, is disclosed herein, in which the barrier mechanism includes two wheels and a barrier belt loop. The two wheels are respectively installed on a top terminal and a bottom terminal of an edge of the disk insertion opening of the magazine. A barrier belt loop which is used for selectively traverse one of the plurality of disk holding members, includes an inner section with a traversing recess carved therein. The inner section is adjacent to the disk insertion opening of the magazine of the disk changer device, and the mechanical coupling between the barrier belt loop and the processing mechanism enables the traversing recess constantly aligned with the optical pick-up unit. Accordingly, the traversing recess is horizontally aligned with the predetermined disk holding member, thereby the procedure enables the drafting unit to extract the predetermined disk holding member through the traversing recess into the optical pick-up unit.

Abstract: A disk drive includes a chassis and first and second disk-positioning members mounted respectively on two opposite sides of the chassis. The first and second disk-positioning members have two straight inner portions extending perpendicularly and respectively from the opposite sides of the chassis to define a first distance therebetween, and two outer portions extending inclinedly and respectively from the inner straight portions in such a manner to define a second distance therebetween. The second distance is longer than the first distance. When an optical disk is moved to a reading and/or writing position from a temporary position, the inclined outer portions of the first and second disk-positioning members are spaced apart from the disk to permit smooth rotation thereof.

Abstract: The present invention relates to a disc guiding mechanism, having: a main body which provided with a teeth array at one side; a first sliding bar and a second sliding bar both of which are provided on the main body; a transmission element provided on the main body and engaged with both of the sliding bars; a first hook and a second hook rotatably provided on each sliding bar respectively; and a first elastic member and a second elastic member provided on each sliding bar to provide an elasticity on the hooks. According to the disc guiding mechanism of the present invention, a disc is guided by the hooks and carried into an optical disc device, the transmission element restricts the first and the second sliding bars to slide symmetrically, so that the disc is guided and carried in a correct direction. Accordingly, a disc jamming in the optical disc device resulted from loading in an incorrect direction is avoided.

Abstract: The present invention is directed to a disk holding device for use in an optical disk reading device that accurately receives and positions an optical disk inserted into the optical disk reading device. The disk holding device comprises a substrate, a holding frame, two holding rods, two guide pins integrally formed on the corresponding holding rods and a sliding plate. Two gear racks are integrally formed with the holding frame, and the two spur gears are integrally formed on top surfaces of the holding rods. Thus, two spur gears of two holding rods respectively mesh the gear racks of the holding frame when the optical disk reading is in use. Further, the sliding plate functions to keep a positioning pin disposed on top surface of the holding rod in place, thereby causing the holding rods to be away from the optical disk when the optical disk reading device is in use.

Abstract: A transmission apparatus includes a gear having a plurality of gear teeth and a rack having a plurality of rack teeth to mesh with the gear teeth. The rack further has an end formed as a cantilever beam structure. In an initial contact of the gear teeth with the rack teeth at the cantilever beam structure of the rack, the cantilever beam structure can deflect to buffer an impact resulted from the contact so that the meshing of the gear teeth and the rack teeth can be much smoother and possible collision in between can also be avoided.
