Abstract

An information processing unit, such as a mobile phone, equipped with a fingerprint sensor and reconciles size reduction with operability at a high level. Adjacent to an operation panel is 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. An information 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 than the first slope 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 a part of a sensing surface of the fingerprint sweep sensor protrudes above an inner surface of the groove.

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

3. The information processing unit according to claim 1, wherein the part of the sensing surface of the fingerprint sweep sensor which protrudes above an inner surface of the groove is an edge of the sensing surface of the fingerprint sweep sensor.
