Abstract

A scanner, comprising: a shell with a transparent flat plate for placing a scanning target; a scanning module movably disposed in the housing for scanning the target through the transparent plate; a cable connected between the scanning module and the shell; and a limiting piece fixed on the scanning module for limiting the cable from contacting the transparent flat plate.

Description

Scanner

Technical field

The present invention relates to a kind of scanner.

Background technology

Scanner is a kind of common electronic product, is used for file or picture etc. is scanned into e-file, further processes on computers for the user.

Fig. 1 represents known scanner 10.Scanner 10 comprises housing 11, scan module 12 and winding displacement 13.Housing 11 has transparent plate 14, is available for users to file to be scanned is placed on the transparent plate 14.Scan module 12 is arranged in the housing 11, can move forward and backward so that by transparent plate 14 scannings file to be scanned.Winding displacement 13 is connected between scan module 12 and the housing 11, is used to provide the required power supply of scan module 12 and control signal etc.

When scan module 12 moves forward and backward, winding displacement 13 will contact the lower surface of transparent plate 14 repeatedly and produce scratch.Because the image quality the when cleanliness factor of transparent plate 14 can influence scanning, winding displacement 13 will cause scan module 12 can not correctly scan file to be scanned at the left scratch of the lower surface of transparent plate 14.

Summary of the invention

Therefore, the objective of the invention is to utilize the limited part that is fixed in scan module, limit winding displacement and can not contact transparent plate, to avoid the lower surface scratch of winding displacement with transparent plate.

The invention provides a kind of scanner, comprising: a housing has a transparent plate, in order to place the one scan target; The one scan module movably is arranged in this housing, in order to scan target by transparent plate scanning; One cable is connected between scan module and the housing; And a limited part, be fixed in scan module, can not contact transparent plate in order to the restriction cable.

For making the above-mentioned purpose of the present invention, feature and advantage can more obvious easy to understand, elaborate especially exemplified by preferred embodiment and conjunction with figs. below.

Embodiment

Main design of the present invention is to utilize the limited part that is fixed in scan module, limits winding displacement and can not contact transparent plate, to avoid the lower surface scratch of winding displacement with transparent plate, causes scan module can't correctly scan file to be scanned.

Fig. 2 a represents scanner 20 of the present invention.Scanner 20 comprises housing 21, scan module 22, winding displacement 23 and limited part 24a.Housing 21 has transparent plate 25, is available for users to file to be scanned is placed on the transparent plate 25.Scan module 22 is arranged in the housing 21, can move forward and backward so that by transparent plate 25 scannings file to be scanned.Winding displacement 23 is pliability flat cable (FFC), is connected between scan module 22 and the housing 21, is used to provide the required power supply of scan module 22 and control signal etc.Limited part 24a is fixed on the scan module 22, be used for limiting winding displacement 23 and can not contact transparent plate 25, when avoiding scan module 22 to move forward and backward, winding displacement 23 contacts transparent plate 25 repeatedly and with the lower surface scratch of transparent plate 25, causes scan module 22 can't correctly scan file to be scanned.

Fig. 2 b is illustrated in the scanner 20 of the present invention, and limited part 24a is directly fixed on scan module 22 to paste mode.Fig. 2 c is illustrated in the scanner 20 of the present invention, and limited part 24a is fixed in scan module 22 in the C clamp mode.Shown in Fig. 2 b and 2c, limited part 24a can be a polyester film, claims the MYLAR film again, is directly fixed on scan module 22 to paste mode, also can be sheet metal, is fixed in scan module 22 in the C clamp mode.

Limited part herein can adopt the various multi-form above-mentioned functions that reach.For example, among Fig. 2 a, 2b and the 2c, large-sized limited part 24a is set directly between transparent plate 25 and the winding displacement 23, transparent plate 25 and winding displacement 23 is separated, to avoid winding displacement 23 contact transparent plates 25.At this moment, no matter limited part 24a is sheet metal or polyester film, all is flexual and has the bending recovery.

Fig. 3 represents that when scan module 22 moved to foremost, limited part 24a was bent into L shaped upward view.As shown in Figure 3, when scan module 22 moved to foremost, large-sized limited part 24a can be bent into L shaped, with the problem of avoiding limited part 24a to cause scan module 22 not move forward.And when scan module 22 when mobile backward foremost, limited part 24a can reply gradually and be original shape.Here, the tip designs of limited part 24a can also be become little knuckle 26, make when scan module 22 moves forward, little knuckle 26 can guide limited part 24a easier be bent into L shaped.

Fig. 4 a is illustrated in the scanner 20 of the present invention, adopts the limited part 24b of another kind of form.Shown in Fig. 4 a, undersized limited part 24b is fixed on the junction of scan module 22 and winding displacement 23.At this moment, limited part 24b is contact winding displacement 23 in fact closely, and forces in winding displacement 23, press down with the part that winding displacement 23 is connected scan module 22, and then the angle between adjustment winding displacement 23 and the scan module 22.In other words, limited part 24b forces in winding displacement 23, and the distance between transparent plate 25 and the winding displacement 23 is widened, and can guarantee that winding displacement 23 can not contact transparent plate 25.

Fig. 4 b is illustrated in the scanner 20 of the present invention, and the limited part 24b of another kind of form is directly fixed on scan module 22 to paste mode.Fig. 4 c is illustrated in the scanner 20 of the present invention, and the limited part 24b of another kind of form is fixed in scan module 22 in the C clamp mode.Shown in Fig. 4 b and 4c,, limited part 24b can be a polyester film, claims the MYLAR film again, is directly fixed on scan module 22 to paste mode, also can be sheet metal, is fixed in scan module 22 in the C clamp mode.

Though the present invention discloses with a preferred embodiment; but it is not that any those skilled in the art is not breaking away from design of the present invention and scope in order to qualification the present invention; can make various changes and retouching, so protection scope of the present invention is defined with accompanying Claim.
