Utility model content
The purpose of this utility model is to provide a kind of paper texture Acquisition Instrument, use this paper texture Acquisition Instrument can gather paper texture information clearly, become the uniqueness voucher differentiating that bill is true and false, combine with coding techniques, mechanically actuated, identification, can overcome existing bill anti-counterfeit technology by artificial cognition, deficiency that error rate is high.Gather the feature of paper texture information clearly for this appliance requires, design is applicable to carrying backlight and microscopical structural member.
A kind of paper texture Acquisition Instrument structural design, comprising: the connection member of the described image collecting device of image collecting device, light source adjustment device and support and described light source adjustment device;
Described image collecting device comprises high resolving power digit microscope and imageing sensor;
Described light source adjustment device comprises high even photosensitiveness planar light source and light source controller;
Described connection member comprises primary structural component and light source fixing part;
High resolving power digit microscope is fixed on described primary structural component by screw.
Described light source needs brightness and the higher white light plane light source of uniformity coefficient.In structure member design part, light source is carried out embedded design, primary structural component inside has screw for fixed light source, consider and will retain light source surface maximum exiting surface and aesthetic property, also provide a kind of light source fixing part, beautifies light source for fixed light source;
Primary structural component sidewall leaves power lead outlet, light source fixing part and light source controller is linked together, make overall appearance consistance high by power lead.
Because described instrument will detect paper document in actual applications, generally such quality of materials is comparatively light, and not easily locate, therefore at light source surface design metal clips, for fixing paper document, metal clips elasticity is controlled by nut.
Microscope connecting hole is left, for connecting microscope in primary structural component side.
The beneficial effects of the utility model are: fill up the blank not having special paper texture collection instrument in the market, the uniqueness of paper texture information is combined with bill anti-counterfeit technology, there is extraordinary robustness, security, effectively can stop the forgery of bill, instrument overall design is simple, good looking appearance, simple portable, easy to operate.
