#The embodiment of this invention is described hereafter while referring to the accompanying drawings.

#FIG. 2 is a block diagram showing the fingerprint check device relating to the embodiment of this invention. In a fingerprint check device 1, the overall operation is controlled by a system controller 3 in response to user operation input by way of a key entry section 2.

#More specifically, when the user selects the registration process in the fingerprint check device 1, a fingerprint data D1 input from a fingerprint data entry section 4 is input to the fingerprint check memory 6. This fingerprint data D1 is registered and a fingerprint data base 5 created. When the user enters a request for a fingerprint check (match), the fingerprint data D2 to be checked is input to the fingerprint check memory 6 by way of the fingerprint data entry section 4. Further, the fingerprint data D2 taken into the fingerprint check memory 6, and the fingerprint data D1 registered in the fingerprint data base 5 are input to the match detector 7. A collation rate to a degree indicating a fingerprint match is detected in this match detector 7. Based on a check of the collation (match) rate, the system controller 3 of the fingerprint check device 1 then outputs the fingerprint check results to an external device.
