Embodiment Construction

[0018] figure 1 It is a schematic diagram of the connection device for the optical pickup head driving device used in the optical drive. The optical pickup drive device includes a power unit 30 for driving a lead screw 20 to rotate, an optical pickup carrier base 40 for carrying an optical pickup (not shown in the figure), a connecting device 10, The carrying base 40 and the lead screw 20 are used for connecting the optical pickup head. In this way, the connecting device 10 can drive the optical pick-up head carrying base 40 to move the optical pick-up head 40 along the lead screw 20 .

[0019] refer to Figure 2a , Figure 2b and Figure 2c , the connection device 10 of the optical pickup drive device of the present invention includes a main body (main body) 11, a first elastic body (first elastic body) 12, a tooth-like device (tooth-like) 13, a restriction device (restriction device) 14 , an extended portion 111 and a limited portion 112 . The extension part 111 exten...

Abstract

The invention relates to an optical reading head driving apparatus and coupling device including a connecting equipment and a guide screw, wherein the connecting equipment includes a main block, a first elastic body, a toothed equipment and a limitation equipment, the device further comprises a second elastic body, a power arrangement and an optical reading head bearing dock.

Description

technical field [0001] The present invention relates to a connecting device, in particular to a connecting device for a driving device of an optical pick-up. Background technique [0002] The optical pick-up head is used to read or record data on an optical disc, such as a digital video disc (DVD) or a compact disc (CD). The method of reading is that the optical pickup head sends laser light to the dent of the disc storing data, and then receives the reflected laser light to identify the data recorded on the disc. [0003] Generally speaking, when the optical pick-up head reads data, the optical disc rotates, and the optical pick-up head moves in the radial direction of the optical disc, so that the optical pick-up head can read every place on the optical disc. Such as Figure 4 As shown, the base 9 carrying the optical pick-up head (not shown in the figure) is usually connected to a connecting body 7, and the connecting body 7 has a tooth 1 thereon. The teeth 1 are engage...
