してもよい。(Function) According to the present invention, for example, when a finger is not set in the fingerprint detection section, only the sub power supply is connected to the detection circuit,
The main power (14) is not turned on to the fingerprint verification unit (15). Then, when the finger is set, the input signal Si causes the output signal $1 of "1" to be output from the flip-flop (17), as shown in FIG.
is turned on, and power is supplied to the fingerprint verification unit (15). Therefore, when the fingerprint verification is completed, the
The end signal S2 of "1" is input to the flip-flop (17) and reset, the output signal S becomes r□, and the main power supply (14) is cut off. Note that instead of the fingerprint verification end signal, a time signal from a timer may be used.
このように構成することにより、指紋照合が行われる時
のみ、指紋照合部（１５）に電力が供給され、消費電力

なくなる。As shown in this figure, the power supply from the main power supply 14 to the fingerprint verification unit 15 is controlled by the output signal SI from the detection circuit 13. By detecting the attachment of the flip-flop 17 or the setting of a finger, an input signal (positive pulse) Si is sent to the input terminal S of the flip-flop 17. Then, an output signal S of "1" is output from the flip-flop 17, the main power supply 14 is turned on, and power is supplied to the fingerprint matching section 15. Then, when the fingerprint verification is completed in the fingerprint verification section 15, the completion signal (positive pulse) S! is output, and the flip signal is output via the OR circuit 16.
It is sent to the input terminal R of the flop 17. Then, the output signal Sl of the flip-flop 17 becomes "0", the main power supply 14 is cut off, and power is no longer supplied to the fingerprint verification section 15.

If it is detected that this is the case, the monitor unit 18 sends out an off signal S. The off signal S,
is sent to the input terminal R of the flip-flop 17 via the OR circuit 16, and the main power supply 14 is cut off.
The power supply to 5 is stopped.
