Abstract
The biometric information input apparatus comprises a fingerprint sensor which detects biometric information, and moisture absorbing units and which are arranged adjacent to the fingerprint sensor and absorb moisture. The moisture absorbing units and have a groove structure which generates a capillary phenomenon. The fingerprint sensor is of the sweep type which scans biometric information through relative displacement with the finger, and is formed in parallel with the direction of relative displacement between the groove structure and the finger. The groove structure has a width smaller than the pitch of the ridges of an average fingerprint.
Claims6
A biometric information input apparatus comprising:
- a biometric information detecting unit which detects a fingerprint during a relative displacement of the biometric information detecting unit and the living individual's body part
- which is a fingertip;
- and
- a grooved structure surface part which has a groove structure that includes plural grooves formed parallel to a direction of said relative displacement to guide said living individual's body part along a movement direction,
- and has a first part and a second part, the detection unit being arranged between the first part and the second part along the movement direction,
- wherein the first part of the groove structure surface part is at least arranged before a finger touches said biometric information detecting unit, and
- said grooves have a groove width smaller than an average ridge pitch, and the groove structure surface generates a capillary phenomenon to absorb a moisture.
