Problems solved by technology
[0002] A fingerprint reader is a device that scans and reads user information through finger fingerprints. It is generally used in access control systems. However, this type of reader has some disadvantages. For example, the infrared scanning light is always exposed, which is easy to cause false scanning. problem, and the problem of inaccurate scanning occurs. In addition, in the process of repeated use, the problem of inaccurate reading of the next user's fingerprint due to the fingerprint attached by the previous person after use also often occurs. A fingerprint reader with automatic cleaning function described in the invention can solve the above problems

The fingerprint reader with the automatic cleaning function comprises a shell, a sliding cavity with a leftward opening is formed in the shell, sliding blocks are arranged on the upper wall and the lower wall of the sliding cavity in a left-right sliding mode, a glass plate is fixedly arranged between the two sliding blocks, and the extending part of the glass plate extends out of the outside. According to the invention, through the mutual abutting connection of the two arc-shaped sliding plates, the infrared scanning head is prevented from being directly exposed to the outside, so that the problem of wrong scanning is effectively prevented. In addition, through ingenious transmission control in the device, when the finger leaves the surface of the glass plate, the surface of the glass plate is automatically cleaned, and the accuracy of next use is effectively improved.
