The contact-type image sensor is characterized in that the light source comprises different lighting light sources of different wavelengths; the frame is at least provided with two rows of lenses, the sensor substrate is arranged below each row of lenses, and the sensor substrate is provided with the photosensitive chip. The contact-type image sensor is provided with the light sources of different wavelengths; and after light emitted from the light source irradiates the original manuscript, optical signals carried in the reflected light are different as the light absorption and reflection degrees of original manuscript on various lights are different. The photosensitive chip of one type can clearly receive one specific type of optical signal or a plurality of specific types of optical signals; reflected optical signals are collected to the specific photosensitive chip by the lenses; and the photosensitive chip converts the reflected optical signals into electrical signals, information obtained by each row of specific photosensitive chips is integrated, and thus the false proof mark can be comprehensively and clearly read to achieve the purposes of realizing multiple native resolution, multifunctional image reading and identifying fact or fiction.
Description
Technical field
The utility model relates to image read-out, and particularly a kind of decapacitation is read outside the visible images such as ruddiness, green glow, blue light, also can read the contact-type image sensor of anti-fake marks such as infrared light commonly used at present, ultraviolet light.
Background technology
As Fig. 1 is the sectional drawing of existing contact-type image sensor, 1 is illuminating source among the figure, the 5th, lens, the 4th, the sensitive chip (photosensitive integrated circuit) of receiver lens 5 light that converges, the 3rd, the sensor base plate of the photosensitive integrated circuit 4 that lift-launch is arranged in a straight line, the 2nd, hold light source 1, lens 5, the framework of sensor base plate 3,6 are arranged on the light-passing board of the lift-launch original copy on the framework 2,7 is original copy, in above-mentioned contact-type image sensor, light source 1 be provided with two kinds, a kind of is to be provided with the closed pockets that holds light source 1 on framework 2, the wide part that light source 1 sends sees through light-passing board 6 with about 45, shine on the original copy 7 of outside, another kind is to be provided with the groove that holds light source 1 on framework 2, be provided with light source 1 in the groove, light source 1 is made up of light source and leaded light post, leaded light post and light-passing board are about 45 °, light source sees through light-passing board 6 through the light that the leaded light post sends with about 45, shine on the original copy 7 of outside, lens 5 are vertical configuration with light-passing board 6, as mentioned above, the wide part that light source 1 sends sees through light-passing board 6 with about 45, shine on the original copy 7 of outside, original copy 7 partially absorbs back reflection with light, these reverberation pass light-passing board 6, wherein a part is collected by lens 5 with the vertical substantially light of light-passing board 6, shine the photosensitive area of the sensitive chip 4 on the sensor base plate 3, sensitive chip 4 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 formed, the light of reception converts the signal of telecommunication 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.
Have following problem in the above-mentioned contact-type image sensor: the light that light source sends enters light-passing board with about 45 ° angle, shines then on the original copy, and original copy reflects away these light, and reverberation enters lens, is pooled on the sensitive chip.And we know, many anti-fake marks go irradiation different anti-counterfeiting information can occur with the light wave of different wavelength, and because various light wavelength differences, behind the light scioptics, sensitive chip to light to accept the position also different, if only accept all anti-counterfeiting information, must receive reverberation fully clearly and bring our information with row's sensitive chip.
Summary of the invention
Technical problem to be solved in the utility model is: change the light source of existing contact-type image sensor and the exhaust position of sensitive chip, propose a kind ofly can clearly read normal image, read the contact-type image sensor of multiple band anti-fake mark simultaneously.
The utility model can reach by following measure:
A kind of contact-type image sensor, comprise sensor base plate, the sensitive chip that carries on the sensor base plate, be provided with lens above the sensitive chip, the side of lens is provided with light source, can hold the sensor substrate, lens, the framework of light source, the top of framework is provided with the light-passing board that carries original copy, it is characterized in that light source is made up of the different illuminating source of multi-wavelength, at least be provided with two row's lens in the framework, all be provided with sensor base plate under every row's lens, sensor base plate is provided with sensitive chip, with according to receiving the different light of wavelength, uses the different sensitive chip of model, can the resolution of different stage be set to all types of chips according to the requirement of the distinguishing ability and the speed of discriminating simultaneously.
Lens in the utility model are perpendicular with the sensor base plate that carries sensitive chip, so that photographic department can better be accepted the light signal of reflected back.
Light source in the utility model has two kinds of illuminating sources that wavelength is different at least, light enters light-passing board with certain angle, shine on the original copy, shine light on the original copy by original copy reflected back light-passing board, these reverberation compile through lens, and the anti-false signal that the light that the specific sensitive chip of lens below can be specific with it is taken back is converted into the signal of telecommunication clearly.
The utility model light source sees through light-passing board, the light that penetrates from light source enters light-passing board, shine on the original copy, shine light on the original copy by original copy reflected back light-passing board, these reverberation compile through lens, and the anti-false signal that the light that the specific sensitive chip of lens below can be specific with it is taken back is converted into the signal of telecommunication clearly.The informix that the specific sensitive chip of each row is obtained so just can comprehensively read anti-counterfeiting mark together clearly then, reaches many resolutions, multi-functional reading images, the purpose of discerning the false from the genuine.
