The utility model at least comprises the following parts: a light source which can emit light and make the light irradiate on the manuscript, a transparent glass board, a sensor base board; a light-sensing part is arranged on the sensor base, a lens is arranged between the transparent glass board and the light-sensing part; and the utility model also comprises a frame which can hold the above light source, the lens and the sensor base board; the transparent glass board is stuck on the upper part of the surface of the whole frame, the utility model can be widely used in the image sensor field.
Description
Technical field: the utility model relates to a kind of image read-out, is a kind of contact-type image sensor specifically.
Background technology: Fig. 5 is the sectional drawing of existing contact-type image sensor.10 is illuminating sources among the figure, the 20th, lens, the 30th, the photographic department (photosensitive integrated circuit) of receiver lens 20 light that converges, the 40th, the sensor base plate of the photosensitive integrated circuit 30 that lift-launch is arranged in a straight line, 50a is a transparency glass plate, the 60th, hold the framework of light source 10, lens 20, sensor base plate 40, transparency glass plate 50a.90a is the original copy operating path.
In above-mentioned contact-type image sensor, the light that light source 10 sends, see through transparency glass plate 50a, be radiated on the original copy literal black region on original copy, light is absorbed, and in other white undercolor region of original copy, light almost 100% is reflected, and these reflected light pass transparency glass plate 50a again, collected by lens 20, shine the photosensitive area of the photographic department 30 on the sensor base plate 40.Photographic department 30 be by many photosensitive areas and can will shine the light of each photosensitive area carry out opto-electronic conversion, and in sensor base plate 40 up one-tenth picture signals.Catoptrical strong and weak different, also just different in the power of the picture signal of sensor base plate 40 up one-tenth.
But above-mentioned contact-type image sensor is because transparency glass plate 50a is higher than the surface of framework 60, therefore, original copy is when entering into the contact-type image sensor surface, run into easily on the step that transparency glass plate 50a height comes out, original copy is stuck in the paper feed process, can not normally move.
Fig. 6 is the sectional drawing of Japanese kokai publication hei 6-18814 number existing contact-type image sensor, and 50b is a transparency glass plate among the figure, and 90b is the original copy operating path, and other parts are identical with Fig. 5.
In this contact-type image sensor, because the surface of framework 60 is higher than the surface of transparency glass plate 50b, therefore, the operating path 90b of original copy also must be forniciform, even but like this, in the paper delivery process of original copy, original copy is also blocked by the frame plate edge of projection easily, makes it and can not normally move.
Fig. 7 is the sectional drawing of TOHKEMY 2001-326790 number existing contact-type image sensor, and 50c transparency glass plate among the figure, 90c are original copy operation roads, and other parts are identical with Fig. 5.
In this contact-type image sensor, the transparency glass plate 50c that has step is very difficult to processing, and, though the surface of transparency glass plate 50c is identical with the surface elevation of framework 60, but because there is the slit in the existence of tolerance between transparency glass plate 50c edge and the framework 60.In the original copy transport process, dust, foreign matter fall into the slit easily, and when transparency glass plate 50c is subjected to staiing need be with organic solvent wipings such as ethanol the time, organic solvent and dust also are stacked in the slit easily, when original copy touches these dusts or foreign matter once more, cause the original copy contamination easily or stain the clear glass surface once more, cause the reading images deterioration.In addition, because the machining precision of framework 60 and the deviation of transparency glass plate 50c thickness, the surface of transparency glass plate 50c and framework 60 is difficult to accomplish highly identical, also has the problem of paperboard, and original copy can not normally be moved.
Summary of the invention: technical problem to be solved in the utility model: as mentioned above, existing contact-type image sensor is different with the height of framework owing to transparency glass plate, the problem of original copy paperboard when causing paper feed or paper delivery easily.In addition, when transparency glass plate is identical with the framework surface elevation, owing to have the slit between clear glass panel edges and the framework, in the original copy transport process, dust, foreign matter fall into the slit easily, and are subjected to staiing need be with organic solvent wipings such as ethanol the time when transparency glass plate, organic solvent and dust also are stacked in the slit easily, when original copy touches these foreign matters once more, cause the original copy contamination easily or stain the clear glass surface once more, make the deterioration of image quality that reads.
The utility model is exactly in order to overcome these problems of existing contact-type image sensor, provide a kind of original copy the contact-type image sensor of paperboard in transmission process, can not occur, and can not make dust accretions cause contamination once more yet, cause the reading images quality to descend owing to the machining precision problem produces the slit.
The utility model comprises at least with the lower part: can send light and make illumination be mapped to light source, transparency glass plate, sensor base plate on the original copy, sensor base plate is provided with photographic department, be provided with lens between transparency glass plate and the photographic department, and the framework that can hold fixing above-mentioned light source, lens and sensor base plate.Transparency glass plate sticks on the top on whole framework surface.
The above-mentioned upper surface that sticks on the transparency glass plate of whole framework upper surface has at least a long limit that certain chamfering is arranged.
A kind of contact-type image sensor, at least comprise with the lower part: can send light and make illumination be mapped to light source, transparency glass plate, sensor base plate on the original copy, sensor base plate is provided with photographic department, be provided with lens between transparency glass plate and the photographic department, and the framework that can hold fixing above-mentioned light source, lens and sensor base plate.The outside on one side of frame upper surface is to upper process, and the aspect ratio transparency glass plate of projection is slightly high, and the long limit of transparency glass plate one side and the jut of framework are close, and the long limit of opposite side sticks on the upper surface that framework does not have projection.
Above-mentioned have a long limit to stick on framework not have the transparency glass plate on protrusion surface top to have at least a long limit that certain chamfering is arranged.
As mentioned above, the utility model is because transparency glass plate sticks on whole framework upper surface or has at least a long limit to stick on the framework upper surface, and the upper surface of transparency glass plate has at least a long limit that certain chamfering is arranged, so have following effect:
1) because transparency glass plate sticks on whole framework upper surface or has at least a long limit to stick on the framework upper surface, and the upper surface of transparency glass plate has at least a long limit that certain chamfering is arranged, make on the original copy operating path without any stopping, overcome because the transparency glass plate surface is higher than or is lower than the problem of the original copy paperboard that is caused on the framework surface, made the original copy in transmission process can trouble-free operation.
2) because transparency glass plate sticks on whole framework upper surface or has at least a long limit to stick on the framework upper surface, and the upper surface of transparency glass plate has at least a long limit that certain chamfering is arranged, overcome because the deviation generation slit of machining precision makes dust accretions cause the problem of staiing once more, prevented the deterioration of reading images quality.
