Abstract

An identity authentication device including a case member, a fingerprint sensor member being detachable from the case member, a first metal terminal formed in the finger print sensor member and a second metal terminal formed in the case member and electrically connectable with the first metal terminal.

Claims

1. An identity authentication device, comprising:

a case member;

a fingerprint sensor member being detachable from the case member;

a first metal terminal formed in the finger print sensor member; and

a second metal terminal formed in the case member and electrically connectable with the first metal terminal.

2. The identity authentication device according to claim 1, wherein the fingerprint sensor member includes a matrix of detection part detecting fingerprint information as capacitance, a driving circuit part obtaining the fingerprint information and an amplifier circuit part amplifying a voltage signal of the fingerprint information.

3. The identity authentication device according to claim 1, wherein the case member has a concave portion in which the fingerprint sensor member is fitted and the first metal terminal of the fingerprint sensor member is electrically coupled to the second metal terminal of the case member.

4. A fingerprint sensor being detachable from a case member of an identity authentication device and having a first metal terminal that is electrically connectable with a second metal terminal formed in the case member.
