Description
Technical field
The present invention relates to a kind of abrasion-proof device, finger is applied to the abrasion-proof device in the falt bed scanner especially.
Background technology
Soft arranging wire (flat flexible cable; FFC) be connecting line commonly used in a kind of electronic installation, suitable wiring can be provided in narrow space.In falt bed scanner, the optics that includes that scans that moves around just is connected with circuit board by soft arranging wire with the bare engine module (carriage) of photoelectric conversion component.See also Figure 1A and Figure 1B, its be respectively a falt bed scanner on look and the side-looking generalized section.One falt bed scanner generally comprises a loam cake (not shown) and a lower house 10, installing one bare engine module 11, a bare engine module driving mechanism 12, a circuit board 13 and a soft arranging wire 14 in this lower house.This bare engine module 11 is subjected to the drive of the motor of this bare engine module driving mechanism 12 and gear train 121 and moves through a transparent scanning platform 15 belows along track 122, scan to be opposite to file on this scanning platform or photo etc., this bare engine module 11 still sees through soft arranging wire 14 and keeps and being electrically connected of 13 of circuit boards when mobile, to carry out the signal transmission.
Ask for an interview Fig. 2 A, it is the organigram of a traditional soft winding displacement.This soft arranging wire 14 is to coat flexible plastic insulation skins 142 by a flexible Copper Foil conductor piece 141 is outer, and adds in two ends and to strengthen sheet 143 and form.The two end portions of this copper foil 141 is exposed to outside this plastic insulation skin 142, assists application of forces and inserts this bare engine module 11 respectively by this enhancing sheet 143, shown in Fig. 2 B, with (not shown) in the slot of this circuit board 13.In bare engine module 11 moving process, the flexual soft arranging wire 14 of this tool can stretch or bending thereupon, when these soft arranging wire 14 bendings, may produce friction with this transparent scanning platform 15 (being generally glass), shown in Fig. 2 B.Especially for product thickness for the scanner of more and more thinner designer trends, for example be equipped with contact-type image sensor (contact imagesensor; CIS) scanner of bare engine module is more and more, and shorter and shorter distance will make this soft arranging wire 14 bigger with the chance of this glass plate 15 frictions, so dirty on this soft arranging wire 14 will be easy to stick on glassly because of friction, so will have a strong impact on scanning quality.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming of the prior art and a kind of abrasion-proof device that is applied to falt bed scanner be provided, the soft arranging wire in this device not can and the glass plate of scanner between friction takes place and influence scanning quality.
Purpose of the present invention can realize by following measure:
