The utility model discloses to file original manuscript scanning and image photomicrograph, can show the extraction efficiency that improves appraisal material original paper, and then let documentary evidence judicial expertise people on the basis of not mastering the original paper material, must acquire the macroscopic view of document text and the relevant information of details comprehensively as far as possible, the efficiency of handling a case has been improved to apparent landing, has enlarged the scope of accepting cases of document judicial expertise, conveniently carries moreover.
Description
Technical field
This utility model belongs to optical instrumentation field, is specifically related to a kind of portable multifunctional documentary evidence extraction apparatus.
Background technology
Progress along with society; judicial expertise the most progressively becomes the community service work of the marketization; relate to handwriting verification in document judicial expertise work, seal impression identifies that the material of case is paper material; owing to identifying trustee's protection to evidence; case-involving sample or sample material original paper cannot provide the problem of appraisal organization to happen occasionally; the large-scale instruments such as appraisal organization file tester can not take scene, simple flat bed scanner and digital camera to and cannot complete deeply and carefully to extract sample or sample.Additionally, conventionally used portable extraction equipment carries out taking pictures or scan fixing when extraction document material evidence just for two dimensional image, just it is easy to forget if the relevant information of document surveyor's field observation records not in time, even if having recorded conventional images also to be difficult to present, and the digital picture distortion factor of these scanning shoots is high, the work of follow-up identification technology is made to carry out difficulty big, it is impossible to degree of depth ground excavates the integrated information that need to identify file.
Utility model content
(1) to solve the technical problem that
For solving the problems referred to above, the utility model proposes a kind of documentary evidence extraction apparatus portable, multi-functional, efficient.
(2) technical scheme
A kind of portable multifunctional documentary evidence extraction apparatus of the present utility model, including chassis base, transparent original text platform, bilateral LED light source, digital photographing system, CCD sweep mechanism, manuscript retainer ring, shade；Described chassis base is provided with bilateral source switch, picture transfer memory interface；Described transparent original text platform is positioned at the top of chassis base, and transparent original text platform is provided with four manuscript retainer ring, and combine closely bottom transparent original text platform a CCD optical scanning mechanism；Described digital photographing system includes digital camera and fixed support；Described shade is that front operating surface is open, and three side sealing left and right, rear closes structure.
Further, described bilateral LED light source is elongated line source, and both sides are designed with lifting groove, it is achieved two side light sources move up and down.
Further, described shade top is provided with shooting window.
Further, described chassis base is provided with a long slideway, inside has the bassinet structure that fixed support horizontally slips.
(3) beneficial effect
This utility model is compared with prior art, it has the advantages that a kind of portable multifunctional documentary evidence extraction apparatus of the present utility model, after document text 4 fully being fixed by transparent original text platform, at cabinet dark field environment, open the unilateral or light source of bilateral, the effect that sidelight is taken pictures can be realized, conversion by digital camera multiplying power, strengthen file writing, the capturing efficiency of printed text surface information, connected the collecting efficiency controlling to improve image by computer, make that image is more true to nature, information more comprehensively.Document original scanning and image photomicrograph, the extraction efficiency of expert evidence original paper can be significantly improved, and then allow documentary evidence judicial expertise people on the basis of not grasping original paper material, the most comprehensive macroscopic view that must obtain document text and the relevant information of details, considerably improve case handling efficiency, expand the scope of accepting cases of document judicial expertise, and be convenient for carrying.
