Description

The background transitions device and the scanner of scanner
Technical field
The utility model relates to a kind of scanner and background transitions device thereof, relates in particular to a kind of background transitions device that is applied to scanner.
Background technology
In paper feeding scanner, the scanning read head is fixed, and paper can be driven with by the scanning read head by roller, thus scan image.The color of the Background apparatus of present paper feeding scanner is fixed, and (is generally white) when paper is light color, needs manually to change Background apparatus and is dark (being generally black).In other words, when paper was dark color, needing manually to change Background apparatus was light color, when the color of paper and Background apparatus forms contrast, helps the detection of paper edge and the correction of paper sheet askew.
In addition, when the very thin thickness of file and be white, and tow sides all have the situation of dark literal, and when background is white and scanning document when positive, the literal at the file back side or pattern can be saturating to the file front, and cause image disruption.But when if background is dark color, this kind interference then can significantly improve.
When doing the image rectification of scanning read head, the general Background apparatus that also can use white and black, to carry out various parameter adjustments at the output of each photosensory assembly in the scanning read head, make each photosensory assembly reach best sensitization usefulness, thereby make the more approaching real color of the image of obtaining.
Change the way of Background apparatus at present and do black and white (depth) correction for the mode of the manual feed-in correcting sheet of user, but, the user must preserve the black and white correcting sheet that the product supplier is provided in addition, when need proofreading and correct, take out with manual mode feed-in correcting sheet at every turn, very inconvenient.So the automatic background conversion equipment has become the necessary assembly of scanner gradually.
The aligning gear that the TaiWan, China patent discloses a kind of scanner I277339 number comprises that one penetrates correction assembly, a reflection source and the one scan module that light source, has opening.This correction assembly is set in the periphery that this penetrates light source, and this reflection source is relative with this correction assembly.The color range timing, this is proofreaied and correct assembly and rotates an angle, make this reflection source impinge upon the surface of this calibration light source, and reflection ray enters in this scan module.During scanning penetration contribution, this light that penetrates light source passes opening and this penetration contribution of this correction assembly, enters this scan module then.
Therefore, color range before the scanning is proofreaied and correct by a drive unit and is driven the correction assembly, making the surface of proofreading and correct the relative reflection source of assembly is astomous state, and reflection source is radiated at the astomous surface of proofreading and correct assembly, obtains reflection ray with scan module and finishes.
The TaiWan, China patent discloses a kind of many Background apparatus and the means for correcting that utilizes its principle of scanner for M262936 number, comprises a rotating shaft, and axially goes up formation one low light line reflection rate zone and high light line reflectivity regions along this rotating shaft.When this rotating shaft during with the regional corresponding optical module of different reflectivity, thereby provide different scanning background colors, and rotate relative to this optical module when this rotating shaft, but then some scan lines are obtained with as chromaticity correction in this rotating shaft surface of this optical module autorotation.
The TaiWan, China patent has disclosed a kind of paper feeding scanner of tool background switching function for M268837 number.The one scan module is presented a file and a static background assembly that is arranged in scanning area by the one scan district in order to scanning by a paper feed mechanism.Scan module comprises an imageing sensor, lens and at least one speculum.One actuator drives this at least one speculum, makes a wherein position of several different light rays reflectivity of imageing sensor scioptics and this at least one speculum selectivity sensing background assembly, to make the one scan background of sensing file.
But though above-mentioned aligning gear can be via rotating the means for correcting or the mode conversion scanning background of rotation speculum, scanner needs additional space to install drive unit, actuator and means for correcting.Therefore, above-mentioned aligning gear can increase the volume of scanner, does not meet the development trend of electronic device miniaturization.
Summary of the invention
The purpose of this utility model is to provide a kind of volume little at above-mentioned the deficiencies in the prior art, thus the background transitions device of the scanner that the minimizing installing space takies.
Another purpose of the present utility model is to provide a kind of scanner with background transitions device.
For achieving the above object, the background transitions device of scanner provided by the utility model, comprise processing unit and electronic display unit, processing unit is in order to receiving inputted signal, and send a control signal according to input signal, this electronic display unit is in order to receiving this control signal, and changes Show Color according to this control signal.
For achieving the above object, scanner provided by the utility model, comprise a casing, be arranged at paper feed passage in the casing, be arranged at the image imaging module of paper feed passage one side, and the above-mentioned background conversion equipment, the electronic display unit of this background transitions device is arranged at paper feed passage opposite side and is oppositely arranged with the image imaging module.
As mentioned above, the utility model background transitions device can change the background Show Color of electronic display unit according to input signal, has smaller size smaller, has reduced installing space and has taken, thereby help the miniaturization of electronic product, be more suitable for being installed in miniaturization scanner and the handly scanner.
