Problems solved by technology

[0007] However, as mentioned above, when the rotating arm 1 rotates, at the position where the FPCB 7 and the rotating arm 1 are adjacent, the FPCB 7 will touch the side of the rotating arm 1 for a while, and will not touch the rotating arm 1 for a while, and so on. , which will cause disturbance to the rotational operation of the rotary arm 1, and under the influence of this disturbance, the precision of the tracking servo performance will be lowered.

Embodiment Construction

[0025] Embodiments of the FPCB fixing structure of the rocker-arm assembly for an optical record player of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] figure 2 It is a side view of a rocker assembly for an optical record player equipped with the FPCB fixing structure of the present invention. image 3 for figure 2 exploded side view. Figure 4 for figure 2 Enlarged side view of main part. The basic structure of the rocker combination remains the same as in the prior art, where the same parts will still be given the same symbols.

[0027] That is, the rocker arm type assembly includes: a rotating arm 1, which can rotate at a certain angle around a rotating shaft (not shown); a slider 2, which is arranged at the front end of the above-mentioned rotating arm 1; supporter) 3, arranged at the rear end of the above-mentioned rotating arm 1; an integrated optical instrument 4 and a bracket 5, combined and arran...

Abstract

The invention concerns FPCB fixed structure of rock arm type assembly for optical recording player. Connect FPCB to rotate arm, flexible combine V-shaped FPCB leaf spring on V-shaped groove at side of rotate arm; the inner circle surface of leaf spring is stuck ends of FPCB, then even rotate arm works, it can not bring disturbance to operation of rotate arm as FPCB can not touch to rotate arm, which increases precision with following and servo performance of optical recording player.

Description

(1) Technical field [0001] The present invention relates to the FPCB fixing structure of the rocker arm assembly for optical record players, and in particular to a rocker arm for optical record players that minimizes the disturbing force applied to the rotating arm by the FPCB and improves the operability of the rotating arm The FPCB fixing structure of the type combination. (2) Background technology [0002] Generally, there are two types of optical recording and playback devices. One is that the optical pickup moves back and forth in a straight line along the guide shaft to record or play the information on the optical disc. This type of player is called a feed-mode optical recording and playback Another way is that the rotating arm where the optical pickup is located is driven to rotate around the rotating shaft to record or play the information on the optical disc. This method is called a rocker-type optical record player. With the high density of optical discs, the min...
