Abstract

The present invention relates to an information processing unit, such as a mobile phone, equipped with a fingerprint sensor and reconciles size reduction with operability at a high level. The present invention is provided, adjacent to a keypad, with a V-shaped groove which contains a first slope stretching away from the keypad and slanting downward and a second slope stretching further away from the keypad 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 a control pad, wherein:

the casing comprises, adjacent to the control pad, a groove which contains a first slope stretching away from the control pad and slanting downward and a second slope stretching further away from the control pad and slanting upward;

the groove comprises a fingerprint sensor which detects a fingerprint on a finger moved along the first slope and the second slope; and

the first slope and the second slope have mutually different tilt angles.

2. The information processing unit according to claim 1, wherein the first slope has a larger tilt angle than the second slope.

3. The information processing unit according to claim 1, wherein the fingerprint sensor is a fingerprint sweep sensor.

4. The information processing unit according to claim 3, wherein the fingerprint sweep sensor has a surface protruding above an inner surface of the groove.

5. The information processing unit according to claim 3, 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.
