Portable device having fingerprint recognition function
First Claim
Patent Images
1. A portable device having fingerprint recognition function, comprising:
- an image sensing unit, for capturing fingerprint images of a finger;
a microprocessor, linked to the image sensing unit, for recording the fingerprint image of the finger, identifying the fingerprint image of the finger from a fingerprint database, receiving a command signal and transmitting a response signal;
a signal transmitting unit, connected to the microprocessor, for transmitting the command signal and the response signal between the microprocessor and an external command device separated from the portable device,a carrying member, for carrying the image sensing unit, the microprocessor, and the signal transmitting unit; and
a housing, for accommodating the image sensing unit, the microprocessor, and the signal transmitting unit and for confining the carrying member to move partially in and out of the housing,wherein the housing has a first opening for exposing the image sensing unit while the carrying member is pushed out of the housing;
wherein the housing has a cleaning unit disposed away from the first opening for removing residual fingerprint from the image sensing unit while the carrying member moves in and out of the housing; and
wherein the signal transmitting unit is protruded out of the housing when needed to be connected to the external command device and stowed back in the housing when not in use.

Abstract
A portable device having fingerprint recognition function includes an image sensing unit, a microprocessor, a signal transmitting unit, a carrying member, a cleaning unit, and a housing. It is characterized that the cleaning unit removes residual fingerprint from the image sensing unit while the carrying member moves in and out of the housing. The portable device of the present invention is free from fingerprint residue and can reduce security risks.
