Abstract
The present invention relates to a calibrator of a scanner, which is used for seeking the reference of a relative position or an absolute position in the scanner. The calibrator at least comprises a section for generating drop height so as to generate a bright and dark borderline for an image. The section can be formed by utilizing ribs of a housing or generating a groove. In addition, the calibrator comprises a white board as reference white.
Description
Technical field
The present invention relates to a kind of means for correcting, particularly about using testing target and its using method in scanner.
Background technology
Fig. 1 shows the outward appearance of one scan device, and wherein board 30 is the lay down location of scanner critical part, in light source, photoreceptor, digital analog converter, amplifier and transmission interface etc. are arranged.Above the cover frame 20 clear glass 40 is arranged, wherein the material of clear glass 40 also can substitute with other transparent material, as acrylic.Image is towards being placed down on the clear glass 40, and loam cake 10 covers image and just can begin to scan, wherein the direction of scanning by A to A '.Be illustrated in figure 2 as the inner structure that cover frame 20 among Fig. 1 is turned over and sees.Image is placed on clear glass 40 belows up.Proofread and correct because scanner needed to do a black and white before scanning, so a testing target 60 that is positioned at cover frame 20 all can be arranged in the present scanner, wherein to be positioned at glass 40 front ends vertical with the direction of scanning for testing target 60.The direction of scanning is by A to A ', and scanning sequency is to scan testing target 60 scan image more earlier.Testing target 60 outward appearances are a blank 62 and a blackboard 64, as shown in Figure 3.Blank 62 proofreaies and correct and the brightness of definition image for photoreceptor one reference white, gives stable output blank 62 and blackboard 64 intersections for setting the reference that begins scanning place, because intersection can be set to the distance of scanning document.Blackboard itself does not provide with reference to black and proofreaies and correct.The direction of scanning is for sweeping blank 62 earlier, and the sweep-black plate 64 again.
The manufacturing process of testing target is that process black is rectangular on blank, again through being fitted on the clear glass after suitable the cutting.Yet through cutting and fit after have higher tolerance and produce.Moreover the process that cuts can produce more waste material, and the cost of material is improved.
Summary of the invention
Fundamental purpose of the present invention provides a kind of calibrator of scanner, and it is a section to be set in testing target, in order to replace blackboard.Because the moulding simultaneously of section and cover cap, blank does not need to republish into blackboard, and therefore cost reduces.Moreover, can reduce number of assembling steps and assembling tolerance.

Embodiment
Preferred embodiment of the present invention is described below, and the form of section of the present invention has two kinds, and a kind of is the rib (rib) of projection, and another kind is sunk groove.Be illustrated in figure 4 as the inner structure of a cover frame 120, in the middle of clear glass 140 is positioned at, image be placed on up clear glass 140 below, clear glass 140 has a blank 160 by the B end, after having removed a rib (rib) 180.Utilize the moulding design of cover frame 120, the rib 180 of a suitable length is made in die sinking, as shown in Figure 5.Rib 180 is held near B and is vertical with the direction of scanning, and pastes a blank 160 at glass near the B end.Glass 140 is attached in the cover frame 120, and will covers frame 120 and cover on scanner.In the present embodiment with rib 180 and blank 160 as testing target (calibratingtarget).
When scanner came into operation, light source 210 moved to B ' from the beginning of B end, and photoreceptor 220 is received signal simultaneously, as shown in Figure 6.Because of rib 180 in height can produce drop, when the light of light source 201 photoreceptor 220 when X sweeps to Y can't receive reflection ray, as shown in Figure 7.Sectional view when Fig. 8 is the inswept rib 180 of light, reflection ray is stopped by rib 180 makes photoreceptor 220 can't receive light from Z to W.The pattern that is scanned for photoreceptor 220 also as shown in Figure 9, one shadow region is scanned out from Z to W, and pattern is the same with the pattern that prior art is scanned.Fig. 9 scans out the starting point that black and white junction in the pattern can be used as scanning in the present embodiment.
Next another embodiment is described.Be the inner structure of a cover frame 120 as shown in figure 10, in the middle of clear glass 140 is positioned at, image be placed on up transparent 140 below, clear glass 140 has a blank 160 by the B end, after having removed a groove 182.Utilize the moulding design of cover frame 120, the groove 182 of a suitable length is made in die sinking, as shown in figure 11.This groove 182 is held near B and is vertical with the direction of scanning, and pastes a blank 160 at glass near the B end.Glass 140 is attached in the cover frame 120, and will covers frame 120 and cover on scanner.In the present embodiment with groove 182 and blank 160 as testing target (calibrating target).
When scanner came into operation, light source 210 moved to B ' from the beginning of B end, and photoreceptor 220 is received signal simultaneously, as shown in figure 12.Because of groove 182 in height can produce drop, when the light of light source 201 photoreceptor 220 when X sweeps to Y can't receive reflection ray, as shown in figure 13.Sectional view when Figure 14 is the inswept groove 182 of light, reflection ray is stopped by groove 182 makes photoreceptor 220 can't receive light from Z to W.The pattern that is scanned for photoreceptor 220 also as shown in Figure 9, one shadow region is scanned out from Z to W, and pattern is the same with the pattern that prior art is scanned.Fig. 9 scans out the starting point that black and white junction in the pattern can be used as scanning in the present embodiment.
Length, height and width at first embodiment middle rib 180 are all inessential, as long as the drop of rib 180 can produce shade to photoreceptor 220.Similarly length, height and the width of groove 182 are all inessential in second embodiment, as long as the drop of groove 182 can produce shade to photoreceptor 220.Rib or groove and cover cap are integrated in the present invention, and the position is more accurate than pasting blackboard model in the prior art.And the function of blank only is used as the reference white correction, so the position of blank is unimportant, i.e. blank subsides are askew, and also it doesn't matter, and blank all can at the rib or the front and back of groove.In the present invention, blank does not need to print black surround, and cutting makes things convenient for and the material saving.And the precision of blank position can reduce.
In above-mentioned invention, can work as the element that reference location is proofreaied and correct as long as can produce the section of drop, the size of element is only influential to the error of system.Section is shorter, and systematic error is bigger.
