Abstract
The utility model relates to an anti-counterfeit instrument for identifying certificate, which is composed of a main machine body, a base, a light-emitting device and an optical lens. The utility model is characterized in that the main machine body and the base are respectively formed in integration with hard material; the base is provided with the light-emitting device, the main machine body is provided with the optical lens, and the main machine body and the base are connected together by screws. The utility model has the advantages that the structure is simple; the design is reasonable; the manufacture and the operation are easy; the true or counterfeit certificates can be distinguished effectively; the utility model is an ideal identifying instrument which is suitable for widely using in hotels, airports, banks, etc.
Description
The utility model is a kind of certificate false proof identifier.
In the middle of daily life; to use banknote, bankbook and some certificates (as I.D., employee's card, educational background card, residence booklet etc.) through regular meeting; the identity, work unit, academic grade registered permanent residence place etc. that reliable authority are provided in current consumption and savings process and are used for proving a people for people, thus correspondingly right and interests obtained.And, make some unprincipled fellows make a desperate move just because of the singularity of these certificates, and forge these documentary evidences, seek unlawful interests.In order to take precautions against and prevent the generation of this phenomenon, certificate production division has added some false proof means in the process of making certificate, as watermark is set, and adds fluorescent powder etc., in the hope of reaching false proof purpose.Though this method is feasible, because watermark, fluorescence etc. with the naked eye are difficult for differentiating under home, effect is not satisfactory in actual use to make it, causes some unnecessary troubles to people.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and reasonable in design, processing and manufacturing is easy, easy for operation, can effectively differentiate the certificate false proof identifier of the certificate true and false.
The purpose of this utility model is achieved like this: it is made up of main body, base, light-emitting device and optical lens, described main body and base are respectively by the hard material one-shot forming, wherein base is provided with light-emitting device, optical lens is installed on main body, and main body and base through screws link together.
Below in conjunction with accompanying drawing structure of the present utility model is described in further details:
Accompanying drawing 1 is an one-piece construction synoptic diagram of the present utility model.
Accompanying drawing 2 is the electrical schematic diagram of illuminating circuit in the utility model.
Accompanying drawing 3 is the position view of optical lens in the utility model.
See accompanying drawing 1,2,3, the utility model comprises main body 1, base 2, light-emitting device 3 and optical lens 4,5, described main body 1 and base 2 are respectively by the hard material one-shot forming, on base, be provided with light-emitting device 3, wherein light-emitting device 3 scenery with hills and waters seal testing circuit and false proof fluoroscopic examination circuit are formed described watermark detection circuit mountain transformer T, white light W

6Send purple light, fluorescence and blue light, when the high density ultraviolet ray that ultraviolet light produces shines on the certificate, can clearly manifest anti-pseudo-image, and the fluorescence that fluorescent light produces can reach the purpose that represents fluorized marking at fluorized marking surface reflection light when shining on the certificate, pass through the processing such as amplification of optical lens 4,5,6 again, make that observed visual lines is more outstanding, pattern is more clear, thereby the naked eyes that can choose are differentiated the true and false of certificate.Same reason, the utility model also can be carried out real and fake discrimination to banknote.The utility model is owing to adopted said structure, and the discriminating that makes the naked eyes of choosing carry out the certificate true and false becomes a lead-pipe cinch, can effectively prevent spreading of forged certificate, thereby play the effect that checks erroneous ideas at the outset.
In sum, the utility model is simple in structure, and is reasonable in design, and processing and manufacturing is easy, easy for operation, can effectively differentiate the certificate true and false, is suitable in the hotel, airport, bank etc. are located to be extensive use of, and are a kind of desirable discriminating instruments.
