Abstract
The utility model relates to a contact image sensor (CIS). The contact image sensor comprises a frame body serving a support function, wherein an optical lens is arranged on one side inside the frame body; light sources with light guide bodies are arranged on double sides of the lens; a transparent plate is arranged above the lens; a circuit board is arranged below the lens; a photoelectric conversion chip is arranged on the circuit board and under the lens; and a photosensitive window is arranged on the surface of the top of the photoelectric conversion chip and a circuit is arranged inside the photoelectric conversion chip. The contact image sensor is characterized in that an independent transmitting light source is arranged on the other side inside the frame body; and the transmitting light source is embedded in the CIS. Therefore, the integration of the transmitting light source and the CIS is realized. According to the utility model, the information that a transmitting light source on the opposite side transmits an original scanned object can be judged according to the scanning information of the CIS; and when two CISs are adopted oppositely, the transmission information of front and back sides of the original scanned object can be judged simultaneously. The contact image sensor has a widespread application prospect.
Description
Technical field
The utility model relates to a kind of contact-type image sensor, is a kind of contact-type image sensor that sees through light source and CIS one specifically.
Background technology
What existing transmitted light source and CIS were used reads structure as shown in Figure 1, CIS comprises passive framework 1, be provided with optical lens 2 in the framework 1, the both sides of lens 2 are 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 illumination that transmitted light source 7 sends is mapped to (original copy) on the scanned object, the image of scanned object (original copy), literal etc. produce transmitted light, these transmitted lights pass transparent panel 4 again, the part transmitted light enters optical lens 2, the transmitted light 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, finish the image information scanning process of scanned object, its deficiency is can only be to image (literal) information of scanning object (original copy) one side, when image (literal) the front and back information of scanned object (original copy), need conversion original copy both forward and reverse directions to scan once more, operate cumbersome and lose time.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of volume little, not only can scan the positive and negative information of original image (literal) fast, the position that can also quick and precisely scan the positive and negative information of original image (literal) embeds and the supporting use of CIS.
The utility model can reach by following measure:
A kind of contact-type image sensor, comprise passive framework, a side is provided with optical lens in the framework, the both sides of lens are 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, it is characterized in that opposite side is provided with independently transmitted light source in the framework, transmitted light source embeds CIS inside, and realization transmitted light source and CIS's is integrated.
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 are provided with in opposite directions (transmitted light source centrally aligned opto-electronic conversion chip) through support, support or framework are provided with the contribution transmission mechanism, during work, the transmitted light source of two CIS is luminous respectively to shine on the original copy positive and negative, positive and negative transmitted light on the original copy will be accepted by the opto-electronic conversion chip of corresponding CIS like this, the opto-electronic conversion chip 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 positive and negative image information scanning process of scanned object.
The utility model can be judged the positive and negative transmission information of original image (literal) fast, and transmitted light source can use separately when not needing to scan positive and negative information, can be as required in the partial accession of the position CIS that transmission information is arranged.Made things convenient for client's use, and can quick and precisely judge original copy single face information, be with a wide range of applications.
Description of drawings
Fig. 1 is the prior art structural representation.
Fig. 2 is the new a kind of structural representation of this practicality.
