Title: Fingerprint collating device
Inventor: NIIZAKI TAKU
IPC: G06F15/02
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain high security, excellent connectability, operability and portability by collating a fingerprint while making the erect direction of extracted characteristic information coincide with the erect direction of the characteristic information of a preliminarily stored fingerprint. SOLUTION: The case of turning to a fingerprint when the insertion direction of a PC card is from the left to the right and the input direction of the fingerprint is defined as the (x) direction xy coordinates is called an erect image. In such a case, a finger placing sensor 1a detects that a finger of a user is placed. When the insertion direction of the PC card on which finger placing sensors 1a to 1c and a fingerprint input face is turned from a reference direction by 180 deg. and the PC card is inserted from the right to the left, the sensor 1b detects the PC card. Also, when the insertion direction is turned from the reference direction by 90 deg. and the PC card is inserted upward, the sensor 1c detects the PC card.  In the case when the fingerprint input face and the sensors 1a to 1c are united into one, fingerprint images become erect, inverted and orthogonal images, but in the respective images, an erect direction can be decided concerning the detecting finger placing sensors 1a to 1c.
