Abstract
The utility model relates to a contact-type linear array sensor comprising a support and a translucent plate fixed on one side of the support. A mounting cavity is formed on the support; a multi-spectrum light guide strip reflection light source and a receiver are fixedly mounted in the mounting cavity; the incident ray of the multi-spectrum light guide strip reflection light source and the reflection ray of the multi-spectrum light guide strip reflection light source on a to-be-irradiated object form an included angle of 10 to 25 degrees; and the receiver receives the reflected light of the multi-spectrum light guide strip reflection light source on the to-be-irradiated object. The utility model overcomes the shortcoming in the prior art that a common contact-type linear array image sensor is insensitive to adhesive tape and can not detect out defects; by adopting the design, total reflection is formed on the surface of the adhesive tape and a highlighting area is formed on the formed image, so as to achieve the purpose of adhesive tape recognition; and after being combined with various other emitted light sources, the contact-type linear array sensor can suit various paper money discrimination instruments, and has compact structure, stability and accuracy in image information collection, and strong reliability.
Description
Technical field
The utility model relates to a kind of contact linear array transducer.
Background technology
Scanning can be divided into CCD (optocoupler sensor) scanning and CIS scanning.Because CIS scanning does not need the optical mirror slip system, so volume, power consumption are all little than the CCD scanner, therefore relatively be fit to the mobile office occasion, CIS scanning has in recent years obtained developing by leaps and bounds.CIS is the abbreviation of English Contact Image Sensor, both contact linear image array sensors, it is a kind of sensor that light signal is converted into electric signal, the principle of work of CIS is to utilize light source to illuminate picture or material object, CIS scans picture or material object then, images acquired information, and outwards transmit with the form of simulating signal.CIS has little, the in light weight and easy-to-install advantage of volume, is widely used in fields such as diagram form scanner, facsimile recorder.Traditional C IS is generally relatively simple for structure, as employed CIS on the equipment such as scanner, facsimile recorder, has only a leaded light bar, only with emission R G B(red blue green) three coloured light, this CIS lacks the pseudo-means of necessary inspection, therefore can't be used for the pseudo-instrument and equipment of bank note inspection, the incident angle angle of leaded light bar transmitting illuminant is bigger among the particularly above-mentioned CIS, when posting adhesive tape as note surface, this CIS is insensitive to adhesive tape, can't detect when scanned.
Summary of the invention
For the incident angle angle that overcomes common contact-type linear array transducer transmitting illuminant in the prior art bigger, insensitive to adhesive tape, the problem that can't detect, the utility model provides a kind of contact linear array transducer, the compact conformation of this contact linear array transducer, can form total reflection, thereby reach the purpose of identification adhesive tape on adhesive tape surface.
The technical scheme that its technical matters that solves the utility model adopts is: comprise support and be fixed on the light-passing board of support one side, form installation cavity in the support, at the installation cavity internal fixation multispectral leaded light bar reflection source and receiver are installed, the incident ray of multispectral leaded light bar reflection source and the angle of its reflection ray on shone thing are 10 °-25 °, and receiver receives the reflected light of multispectral leaded light bar reflection source on shone thing.
The incident ray of multispectral leaded light bar reflection source and the angle of its reflection ray on shone thing are 17.5 °.
Also fixedly mount infrared leaded light bar transmitted light source and ultraviolet LED array reflection source in installation cavity, receiver receives the reflected light of ultraviolet LED array reflection source on shone thing.
A side relative with light-passing board on the support fixedly mounts wiring board.
The utility model is by above-mentioned specific design, can form total reflection on the adhesive tape surface, on the image that forms, form highlight regions, thereby reach the purpose of identification adhesive tape, after other multiple combination of light sources of launching, can be applicable to the identifier device equipment of various bank note, have that compact conformation, image information collection are stable accurately, the advantage of good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a principle of work synoptic diagram of the present utility model.
Embodiment
As shown in the figure, the utility model comprises support 1 and is fixed on the light-passing board 2 of support 1 one sides, the light-passing board 2 general optical glass that adopt, form installation cavity 3 in the support 1, at installation cavity 3 internal fixation multispectral leaded light bar reflection source 4 and receiver 5 are installed, the incident ray of multispectral leaded light bar reflection source 4 and the angle of its reflection ray on shone thing are 10 °-25 °, and receiver 5 receives the reflected light of multispectral leaded light bar reflection source 4 on shone thing.The optimal selection of the incident ray of multispectral leaded light bar reflection source 4 and the angle of its reflection ray on shone thing is 17.5 °.When being applicable to the identifier device equipment of bank note, shone thing is bank note.Also fixedly mount infrared leaded light bar transmitted light source 6 and ultraviolet LED array reflection source 7 in installation cavity 3, receiver 5 receives the reflected light of ultraviolet LED array reflection source 7 on shone thing.The side fixed installation wiring board 8 relative on the support 1 with light-passing board 2.Ultraviolet LED array reflection source 7 tilts to install in installation cavity 3, and be formed into firing angle between the bank note, be transmitted in that reflected light on the bank note is received by receiver 5 after the processing of circuit of wiring board 8, light signal is converted into electric signal and outwards transmits, and can do the collection of unanimous vote face ultraviolet light reflected image; The incident ray of multispectral leaded light bar reflection source 4 and the angle of its reflection ray on bank note are 10 °-25 °, optimal selection is 17.5 °, the reflected light that is transmitted on the bank note is received after the processing of circuit of wiring board 8 by receiver 5 equally, light signal is converted into electric signal and outwards transmits, can do multispectral reflected image collection, multispectral leaded light bar reflection source 6 can corresponding R G B IR both red, blue, green, infrared 4 kinds of light and various combination thereof, on the bank note if any adhesive tape, R G B four kinds of light of IR can form total reflection on adhesive tape surface, on the image that forms, form highlight regions, thereby reach the purpose of identification adhesive tape; And the transmitted light that infrared leaded light bar transmitted light source 6 is transmitted on the bank note passes bank note, by after the reception of the receiver in another contact linear image array sensor of relative installation light signal being converted into electric signal and outwards transmission, can do the flushing outer light-transmittance pattern collection of unanimous vote.Above-described embodiment only is that the preferred implementation to a kind of contact linear array transducer of the utility model is described; be not that design and scope to utility model limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain of a kind of contact linear array transducer of the utility model.
