Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, embodiment cited below particularly, and conjunction with figs. elaborate.First embodiment:
Based on above-mentioned known scanning module is to be located by one group of strong image or color correction sheet of contrast, and wherein image sensor is to receive this strong and weak different signal of video signal (or chroma response degree), in order to judge the reference position of scanning module.Hereinafter will do more detailed explanation at the structure of the image sensor in the scanning module.
Please also refer to Fig. 1, Fig. 2, wherein Fig. 2 is the synoptic diagram that signal of video signal is incident upon the image sensor of scanning module inside.Image sensor 200 for example is a charge coupled cell (Chargecouple device, CCD), it is to be arranged with the array kenel by one group of sensing born of the same parents (Cell array) 202 to form, and each sensing born of the same parents 202 is in order to receive the signal of video signal M1 of diverse location on the correcting sheet 104.Before and after sensing born of the same parents 202 receive during the very large signal of video signal M1 of strength difference, expression scanning module 110 is just on zone under the correcting sheet 104, and with the reference position (Home position) of this coordinate points as scanning module 110.
From the above, sensing born of the same parents 202 for example are the lattice point on the axes of coordinates, can reflect the position of signal of video signal position on image sensor 200.It should be noted that, when scanning module 110 along F1, when the F2 direction moves, can detect the distance of the reference position of desiring scanning document 106 and scanning module 110, and learn and desire the length of scanning document 106 on F1, F2 direction, again by position and the width of signal of video signal position on the sensing born of the same parents 202 of image sensor 200 of file 106 representatives, in order to judge the width of file 106 on vertical F1, F2 direction.
With regard to known technology, scanning module must be that reference point is judged the coordinate position of desiring scanning document with the correcting sheet, yet this mode has increased replys location and the time of proofreading and correct again.Therefore, the utility model first embodiment proposes a kind of location structure, and it utilizes the specific image signal that is received on the sensing born of the same parents of image sensor, to learn the position at scanning module place.
Please refer to Fig. 3, it illustrates the arrangement plan of a kind of location structure of the utility model first embodiment.Present embodiment is to utilize the location structure 304 of a thin-and-long to be disposed on the inwall of upper shell 300, and its length direction is the rough direction of scanning (being illustrated Y direction) that is parallel to scanning module 310.Location structure 304 can be and strong spacer of upper shell 300 color contrast or location chart etc., and it is attached on the inwall of upper shell 300.In addition, also can location structure 304 and upper shell 300 is integrally formed, it forms a flange or a groove on the inwall of upper shell 300, and with location structure 304 through special processings such as sandblasts or textures, its inwall with upper shell 300 is had contrasts strong difference.In addition, upper shell 300 has one scan form 302, and the length of location structure 304 is can be more than or equal to the length of scanning form 302.
Equally as shown in Figure 3, width or the image of location structure 304 on Y direction is different along with its length direction, the width or the image that are location structure 304 are to change with a ratio along Y direction, A width of ordering or the image width or the image of ordering wherein greater than B, by that analogy.Therefore, when scanning module 310 when Y direction moves, judge the signal of video signal of different in width or image representative, to determine the position at scanning module 310 place on the length direction of location structure 304.
From the above, because scanning module 310 can be studied and judged present position at any time, so do not need to be returned to its reference position and wait for correcting sheet correction position again, the action that scanning module 310 just can directly scan next time.In other words, can directly move on the position of desiring scanning document, thereby save its time of replying the location and proofreading and correct again according to scanning module 310 present positions.
Please refer to Fig. 4, it illustrates the synoptic diagram of image sensor.In the present embodiment, for example utilize the sensing born of the same parents 412 of the frontier area of image sensor 410, in order to receive the signal of video signal M2 of location structure representative, it should be noted that, this signal of video signal M2 can be the signal of different color light, or one picture signal change with a special ratios, or the different chart of a width ratio etc. all can reach the function of location at any time.
Please refer to Fig. 5 A and Fig. 5 B, it illustrates the synoptic diagram of location structure.The profile of location structure 504,506 for example is respectively a long and narrow right-angle triangle and a long and narrow taper triangle, wherein location structure 504,506 width or image scaled difference alongst.In addition, as above-mentioned shown in Figure 3, the profile of location structure 304 for example is one long and narrow trapezoidal, wherein location structure 304 width or image scaled difference alongst.Certainly, be familiar with this skill person, the location structure that also can utilize the non-linear width ratio to change is located, in this no longer being described further more.
By above explanation as can be known, the utility model first embodiment utilizes this location structure so that scanning module is located, in order to determine the position at scanning module place on its moving direction.Second embodiment:
Please refer to Fig. 6, it illustrates the arrangement plan of a kind of location structure of the utility model second embodiment.Present embodiment is to utilize the location structure 604,606 of two thin-and-longs to be disposed on the upper shell 600, and its length direction is rough respectively X-direction and the Y direction of being parallel to.Wherein, width or the image scaled difference of location structure 604 on the X-direction, and width or the image scaled difference of location structure 606 on the Y direction.In addition, location structure the 604, the 606th is equipped on the inwall of upper shell 600, it can be attached on the inwall of upper shell 600 or be integrally formed with the inwall of upper shell 600, and location structure 604,606 can be respectively more than or equal to corresponding scanning form 602 length or width.
From the above, different with first embodiment is that the location structure of X-direction is to determine its sensing born of the same parents pairing coordinate on X-direction in order to auxiliary image sensor.It should be noted that, when scanning module 610 process location structures 604, because location structure 604 each points (as C point, D point) width or image difference in the longitudinal direction, can make the sensing born of the same parents go up the asynchronism(-nization) that signal of video signal stopped of corresponding each point, and make image sensor (not illustrating) can locate the relative position of its sensing born of the same parents on X-direction.
By above explanation as can be known, the utility model second embodiment utilizes this location structure respectively the image sensor of scanning module and scanning module to be located, in order to the position at definite scanning module place on its moving direction, and the pairing coordinate position of sensing born of the same parents of definite image sensor.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limiting the utility model, anyly has the knack of this skill person, in not breaking away from spirit and scope of the present utility model; when being used for a variety of modifications and variations, therefore protection domain of the present utility model is as the criterion with claims.
