Flexible electric circuit board and recording/playing-back device therewith

Abstract

The present invention can prevent a part of a flexible wiring board from being inserted in a gap between a tray and a chassis when the tray is accommodated in the chassis. A flexible wiring board is provided with a first wiring board which is stretched and formed in a B direction, and second wiring boards which are turned back in a direction (A direction) opposite to the direction of the first wiring board. The second wiring boards can be divided into first sections turning to curved parts, and second sections which are formed between the curved parts and terminals. The reinforcement parts are protruded in trapezoidal shapes, and areas of the second sections are enlarged, so that rigidity is increased. As a result, the second sections are prevented from protruding from a gap between a rear end partof the tray and a front end part of the chassis.

Description

technical field [0001] The present invention relates to a flexible circuit board (flexible circuit board) arranged to be flexibly connected between a fixed side and a movable side and to move the curved part corresponding to the movement of the movable side, and a record using the flexible circuit board Record playback equipment. Background technique [0002] A disc device loaded with a recording medium such as a disc-shaped recording medium (hereinafter referred to as "disc") such as a CD-ROM, CD-R, CD-RW, DVD-ROM, or DVD-RAM, With the demand for miniaturization and thinning of notebook personal computers, it is desired to reduce the thickness of the disk drive itself. The space formed between the chassis that supports and enables the tray to fold becomes narrow. [0003] Furthermore, in the tray, there is a turntable for rotationally driving the disk, and laser light is irradiated on the surface of the disk clamped on the turntable to read and record on the disk. The op...

AI Technical Summary

Problems solved by technology

At this time, due to the contact resistance between the top 104a, the bending portion 110a cannot be folded, and even the flexible circuit board 110 will protrude from the gap 108 between the tray 106 and the bottom frame 104. part of 110b

[0009] What's more, the tray 106 continues to move toward the bottom frame 104, and the protruding portion 110b of the aforementioned flexible circuit board 110 between the rear edge portion 106a of the tray and the front edge portion 104b of the bottom frame will be pinched.
