Embodiment 1

[0013] like figure 1 As shown, the novel fingerprint punching machine is composed of a punching machine main body 1 and a fingerprint printing surface 2.

[0014] The fingerprint printing surface 2 is placed at the front end of the main body 1 of the card punching machine. The fingerprint printing surface 2 is made of high-strength engineering glass and is a U-shaped groove surface 2.1. This structure conforms to the radian of the finger and improves the printing accuracy. 2.1 Place it above the fingerprint printing surface 2 to facilitate finger printing. There is no need to turn the finger when extracting the fingerprint, just press the U-shaped pressing surface directly to complete three-sided printing, improving the accuracy of identification.

Abstract

The invention provides a novel fingerprint punched-card machine. The novel fingerprint punched-card machine comprises a punched-card machine main body 1 and a fingerprint impressed surface 2, wherein the fingerprint impressed surface 2 is arranged at the front end of the punched-card machine main body 1, is manufactured by adopting high-strength engineering glass and comprises a U-shaped groove surface 2.1, and the U-shaped groove surface 2.1 is formed above the fingerprint impressed surface 2. The structure of the novel fingerprint punched-card machine conforms to the radians of fingerprints, so that the impressed accuracy is improved, and fingerprint impressing is facilitated; when fingerprints are extracted, fingers do not need to rotate, the three-surface impressing can be completed as long as the U-shaped pressing surface is directly pressed, thus improving the accuracy rate of identity recognition.

Description

technical field [0001] The invention relates to an instrument for collecting fingerprints and recording employment conditions. Background technique [0002] In the existing fingerprint punching machine, the pressing sensing surface in contact with the finger is a plane. When it is necessary to identify the fingerprint for identity verification, three-sided printing is required to extract the complete fingerprint, which requires the operator to rotate the finger on the pressure sensing surface smoothly and at a constant speed. In practical work, it is found that it is not convenient to use this kind of flat fingerprint punching machine to identify fingerprints, and it is easy to cause fuzzy, broken or overlapping fingerprints extracted due to operational errors, so that identity cannot be identified. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a novel fingerprint punching machine with a U-shaped...
