Description
Affiliated technical field
The utility model relates to the image read-out field of telecommunication class, especially a kind of contact-type image sensor.
Background technology
At present, known contact-type image sensor structure is by illuminating source, lens, the photographic department (light sensor) of light that receiver lens converges, the sensor base plate of the photosensitive integrated circuit that lift-launch is arranged in a straight line, glass plate, holding the framework of light source, lens, sensor base plate, glass plate forms, level and smooth frame ends is coated with fixing glue, thereby with lens and frame fixation, is equipped with electronic device on the sensor base plate.
In above-mentioned contact-type image sensor, the light that light source sends, see through glass plate, be radiated on the original copy, the light of the literal black region on original copy is absorbed, and in other white undercolor region of original copy, light almost 100% is reflected, these reverberation pass glass plate again, are collected by lens, shine the photosensitive area of the photographic department on the sensor base plate.Photographic department be by many photosensitive areas and can will shine the light of each photosensitive area carry out opto-electronic conversion, and the drive circuit of signal output is formed.The light that receives converts telecommunications to after overdrive circuit output is outwards exported as image (literal) information.Original copy constantly moves, and the image information of being put down in writing on it (literal) will be read continuously.
But only used a light source in the above-mentioned contact-type image sensor, therefore can apply fixing glue in the framework upper end lens are fixed.In fact in many instances require contact-type image sensor respectively to place a light source in the both sides of lens, at this moment lens can't be fixed lens away from the framework upper edge.
Summary of the invention
The problem that can't fix lens when placing light source in the lens both sides in order to overcome the existing contact imageing sensor, the utility model provides a kind of contact-type image sensor, no matter this imageing sensor is to place light source in lens one side or in the lens both sides, can both effectively lens be fixed.
The technical scheme that its technical problem that solves the utility model adopts is: comprise that being placed on the lens sidepiece can send light and make illumination be mapped to light source, original copy placement section, sensor base plate on the original copy, sensor base plate is provided with light sensor and other electronic device, be provided with lens between original copy placement section and the photographic department, and the framework that can hold fixing above-mentioned light source, lens and sensor base plate, framework is provided with the coating groove that fixed lens is used, the position of this coating groove be positioned at the light source placement location below, be coated with fixing glue in the coating groove lens fixed.
The above-mentioned coating groove that is arranged at light source placement location bottom can only be arranged on a side of lens, and this coating groove can be continuous, also can be interrupted, only lens is carried out continuous or interrupted fixing in a side of lens.
The above-mentioned coating groove that is arranged at light source placement location bottom also can be arranged on the both sides of lens, and this coating groove can be continuous, also can be interrupted, only in the both sides of lens lens is carried out continuous or interrupted fixing.
The beneficial effects of the utility model are because be provided with the fixedly coating groove of usefulness of lens below the light source placement location, to be provided with fixing glue in the coating groove, so also can to carry out well fixing, simple in structure when lens both sides placement light source to lens.
