Problems solved by technology

However, the extended reinforcing plate 134 is very easy to hit the bearing seat 131 or the frame 110 of the optical drive and fall off from the optical pickup head, causing one end of the flexible cable to fail to connect with the pickup module 133
In this way, signal transmission cannot be performed between the reading head module 133 and the circuit board 120

Abstract

An optical drive includes a frame, a circuit board and a movement. The movement includes a carrier, a reading head module, a spindle motor module and flexible cables. The carrier has an opening. The read head module is located above the circuit board and is movably disposed in the opening. The spindle motor module is configured on the carrier and is located at one side of the pickup head module for carrying the optical disk above the pickup head module. The flexible cable is disposed in the opening and has two connection ends, respectively connected to the reading head module and the circuit board. The reading head module at the first position makes the flexible flat cable have a bent portion protruding in a direction opposite to the position of the spindle motor module. The readhead module in the second position stretches the curved portion. The first position is closer to the spindle motor module than the second position.

Description

technical field [0001] The invention relates to an optical drive, and in particular relates to an optical drive with a flexible cable. Background technique [0002] With the development of optoelectronic technology, the application of optoelectronic products is becoming more and more common. Taking the optical drive as an example, the optical pickup head is movably arranged in the optical drive. The optical pickup head is connected to a circuit board by a flat flexible cable (FFC), and the flexible flat cable will follow the optical pickup head. stretch or bend. [0003] Please also refer to Figure 1A and Figure 1B , Figure 1A It is a schematic diagram of a general CD-ROM drive, Figure 1B drawn along Figure 1A A partial cross-sectional view of an optical drive in section line 1B-1B. [0004] The optical drive 100 includes a base 110 , a circuit board 120 and a core 130 . The circuit board 120 is disposed on the bottom plate of the base 110 . The movement 130 is di...
