Description

Living fingerprint stamping device

Technical Field

The utility model relates to the technical field of stamping, in particular to a living fingerprint stamping device.

Background

In the process of fingerprint identification, judicial identification personnel are required to acquire evidence for ten finger fingerprint information of an identified person. When the traditional living body printing sample is used, the ink printing method is used for reflecting the fingerprint image on a card with a certain specification under a certain action condition. This method generally requires standard printing tables, ink and printing rollers (or ink cartridges), printing papers, and the like. When three-side stamping operation is performed, stamping paper needs to be paved on a stamping tabletop, so that the paper edges are level with the tabletop edges; the right and left hands of the right and left stamping person are respectively used for pinching the two ends of the finger of the right and left stamping person, and the finger is rolled on the ink box on three surfaces to be uniformly dipped with ink and then is rolled on a ten-fingerprint card or white paper in the same way.

In practical operation, the stamping person needs to have a flat tabletop with proper height, so that the stamping person can fully relax and not be excessively stressed. When the ink is rolled and the fingerprint is printed, the person to be printed cannot feel hard in the dark, and the whole action is naturally mastered by the person to be printed; when the stamping person operates, the force is required to be uniform in the whole process. Thus, the fingerprint printed by the press is not easy to deform and has higher quality.

In actual authentication work, the smaller authentication person often faces the stronger stamped person, and when the person goes out to investigation and collect the evidence, the stamped person does not have a proper workbench, and the stamped person cannot grasp the action key and cannot cooperate with the authentication person to finish fingerprint collection work due to the fact that the stamped person is too old, language is not easy, intentional interference authentication and other reasons.

Therefore, a portable tool for stamping living fingerprints is needed, which can fully exert subjective activity of an identification person, so that the stamping operation is convenient, the method is not limited by the reasons, and the like, the stamped fingerprints are clear, and the requirements of fingerprint sample cards formulated in program files of all identification institutions are met.
