Abstract

An information processing unit, such as a mobile phone, equipped with a fingerprint sensor and which reconciles size reduction with operability at a high level. Adjacent to an operation panel is located a V-shaped groove which contains a first slope stretching away from the operation panel and slanting downward and a second slope stretching further away from the operation panel and slanting upward, where the V-shaped groove contains a fingerprint sweep sensor which detects a fingerprint on a finger moved along the first slope and the second slope.

Claims

1. A portable processing unit which comprises a casing equipped with an operation section, wherein:

the casing comprises, adjacent to the operation section, a groove which contains a first slope stretching away from the operation section and slanting downward and a second slope stretching further away from the operation section and slanting upward, wherein a finger moves downward along the first slope and the finger moves upward along the second slope;

the groove comprises a fingerprint sweep sensor which detects a fingerprint; and

the first slope and the second slope have mutually different lengths,

wherein an entire sensing surface of the fingerprint sweep sensor protrudes above an inner surface of the groove.

2. The portable telephone according to claim 1, wherein the fingerprint sweep sensor is located in the groove in such a way as to hide a ridge line where an extension surface of the first slope and an extension surface of the second slope meet.

3. The information processing unit according to claim 1, wherein the information processing unit is a portable telephone.
