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.
Claims3
An information processing unit which comprises a casing equipped with an operation section,
- 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,
- 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, and
- wherein a finger moves downward along the first slave and the finger moves upward along the second stove.
