Abstract
The utility model relates to a contact-type image sensor which comprises a frame taking the supporting function, an optical lens arranged inside the frame, a transparent plate arranged above the optical lens, a circuit base plate arranged below the optical lens, and a light source with a light-conductive body structure arranged on the side of the optical lens. The contact-type image sensor is characterized in that a gray ink layer of desired concentration is painted on the housing of the light-conductive body, so that when two CIS light-conductive bodies are arranged opposite to each other, either CIS judges whether the opposite CIS is lighted according to the reflected light from the ink layer of the housing of the opposite CIS; or an ink layer of desired color is painted on the housing of the light-conductive body and used as the scanning background of the opposite CIS. The contact-type image sensor judges where the opposite CIS is lighted according to the scanning data of the CIS, can meet the need of special scanning of CIS by painting the ink of desired color on the housing of the CIS light-conductive body as the scanning background of the opposite CIS, and has wide application prospect.
Description
Technical field:
The utility model relates to a kind of contact-type image sensor, be specifically a kind of on the shell of light conductor the contact-type image sensor of printing-ink.
Background technology:
What existing two CIS were used reads structure as shown in Figure 1, each CIS comprises passive framework 1, be provided with optical lens 2 in the framework 1, one side of lens 2 is provided with the light source 3 of light conductor structure, the top of lens 2 is provided with transparent panel 4, the below of lens 2 is provided with wiring board 6, be positioned on the wiring board 6 lens 2 under be provided with opto-electronic conversion chip 5, opto-electronic conversion chip 5 top surfaces are provided with the sensitization form, inside is provided with circuit, the function of opto-electronic conversion chip 5 is to convert light signal to the signal of telecommunication, during work, the light that light source 3 sends, see through transparent panel 4 and shine (original copy) on the scanned object, image on the scanned object (original copy), literal etc. produce reverberation, these reverberation pass transparent panel 4 again, partial reflection light enters optical lens 2, the reverberation that comes out from optical lens 2 other ends shines on the sensitization form of opto-electronic conversion chip 5, opto-electronic conversion chip 5 converts the light signal that receives to the signal of telecommunication, outwards export as image (literal) information, original copy constantly moves, the image of being put down in writing on it (literal) information will be read continuously, finishes the image information scanning process of scanned object.
The image-scanning device that is used with two CIS scans, when the CIS light source breaks down can not normally light the time, because CIS is sealed in the inside of image-scanning device, can not be observed directly, whether light cumbersome by measuring means detection CIS such as electric current, sometimes also need image-scanning device is dismantled, increased testing staff's workload.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, at the gray ink of the surface printing specific concentrations of CIS light conductor shell, can judge the contact-type image sensor whether CIS lights fast by detecting the optical information that printing ink reflects.
The utility model can reach by following measure:
A kind of contact-type image sensor, comprise passive framework, be provided with optical lens in the framework, one side of lens is provided with the light source of light conductor structure, the top of lens is provided with transparent panel, the below of lens is provided with wiring board, be positioned on the wiring board lens under be provided with the opto-electronic conversion chip, opto-electronic conversion chip top surface is provided with the sensitization form, inside is provided with circuit, the shell that it is characterized in that light conductor is provided with ink lay, that is to say on the shell of light source and be printed with printing ink, the function of opto-electronic conversion chip is to convert light signal to the signal of telecommunication in the utility model, during use, two CIS is provided with in opposite directions, when two CIS do not break down operate as normal, the illumination that CIS2 sends is to the ink lay of CIS1 light conductor shell printing, and the optical information that reflects is obtained by CIS2, and the output of CIS2 is low according to the output to blank sheet of paper, output height according to black paper is easy to judge.When the light source of CIS2 can not normally be lighted, CIS2 can not obtain the optical information that reflects from CIS1 light conductor shell printing ink layer, whether the output of CIS2 is identical with the output on shining black paper, with normal output notable difference is arranged, can judge the light source of CIS2 so fast and light.If the light source of same CIS1 can not normally be lighted, whether the optical information that CIS1 also can reflect by printing ink layer on the CIS2 light conductor shell is judged CIS2 and is lighted.
Can be in the utility model at the colored ink of the shell printing particular color of the light conductor of CIS, can adopt gray ink, red ink, blue ink and Yellow ink etc., the concentration of printing ink also can be diversified, when original copy in the middle of two CIS by the time, be printed on the scanning background that colored ink on the shell of CIS light conductor can be used as opposite CIS and use.
When the utility model can be judged two CIS fast and uses relatively, whether the light source of CIS was normally lighted, and CIS can be provided the background of the special color that scanning needs, and had made things convenient for client's use, had broad application prospects.

Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, a kind of contact-type image sensor, comprise passive framework 1, be provided with optical lens 2 in the framework, one side of lens 2 is provided with the light source 3 of light conductor structure, the gray ink layer 7 of printing specific concentrations on the shell of the light conductor of light source 3, the top of lens 2 is provided with transparent panel 4, the below of lens 2 is provided with wiring board 6, be positioned on the wiring board 6 lens 2 under be provided with opto-electronic conversion chip 5, opto-electronic conversion chip 5 top surfaces are provided with the sensitization form, inside is provided with circuit, two CIS are oppositely arranged during use, (as shown in Figure 3), gray ink 7 is coated with on the shell of light conductor evenly, and the top of lens 2 is provided with transparent panel 4, the below of lens 2 is provided with wiring board 6, be positioned on the wiring board 6 lens 2 under be provided with opto-electronic conversion chip 5, opto-electronic conversion chip 5 top surfaces are provided with the sensitization form, inside is provided with circuit, and the function of opto-electronic conversion chip 5 is to convert light signal to the signal of telecommunication.When two CIS do not break down operate as normal, the illumination that CIS2 sends is on the ink pellet surface 7 of CIS1 light conductor shell printing, and the optical information that reflects is obtained by CIS2, and the output of CIS2 is low according to the output of the acquisition to blank sheet of paper, output height according to obtaining to black paper is easy to judge.When the light source of CIS2 can not normally be lighted, CIS2 can not obtain the optical information that reflects from CIS1 light conductor shell printing-ink 7, the output of CIS2 is identical with the output on shining black paper, with the output that shines on the light conductor shell printing-ink 7 notable difference is arranged, can judge the light source of CIS2 fast and whether light.If the light source of same CIS1 can not normally be lighted, whether the optical information that CIS1 also can reflect by printing-ink 7 on the CIS2 light conductor shell is judged CIS2 and is lighted.
