Abstract

The invention provides a fingerprint collector, which belongs to the technical field of fingerprint identification. It solves the problem of the thickness of the existing fingerprint collector. The fingerprint collector includes a shell and a prism. There is an opening at the top of the front end of the shell. A support frame is arranged in the shell. The prism is arranged on the support frame and the prism is located at the opening. The first reflecting mirror is set, the bottom of the inner rear end of the casing is provided with an image sensor and a lens, and the top of the inner rear end of the outer casing is fixedly connected with a second reflecting mirror arranged obliquely, and the light in the prism passes through the first reflecting mirror and the second reflecting mirror in sequence After reflection, it is transmitted to the image sensor through the lens. The fingerprint collector has the advantage of thin thickness.

Description

technical field [0001] The invention belongs to the technical field of fingerprint identification, and relates to a fingerprint collecting instrument. Background technique [0002] Fingerprint collector refers to a special instrument made according to the characteristics of fingerprints. The characteristic of fingerprints is that everyone is different and remains unchanged throughout life. This feature of fingerprints can be used as an "ID card" representing a person. [0003] In order to identify fingerprints, people have invented fingerprint collectors. For example, Chinese patent literature discloses an optical fingerprint collector [application number: 201520593775.4; authorized announcement number: CN 204926120U]. The collector includes a housing and a prism, and the housing has a front wall , the rear wall and the bottom wall, the front end of the bottom wall is fixedly connected with the front wall, the rear end of the bottom wall is fixedly connected with the rear w...
