IMAGE READ-OUT DEVICE AND USER DISTINCTION METHOD FOR IMAGE READ-OUT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image read-out device and a user distinction method for the image read-out device capable of distinguishing the ID of a user going to use the device without forcing the user to conduct complicated operation. SOLUTION: This device is provided with a receiving antenna 102 receiving an electromagnetic wave transmitted from a PHS terminal; an electromagnetic wave demodulation packet formation device 103 adding an intensity signal to an electromagnetic wave-demodulated digital signal to form a packet data and measuring the intensity of the electromagnetic wave; an ID signal distinction device 107 selecting the most strong intensity packet data stronger than a threshold value from a packet data group and outputting an interruption signal to a scanner portion control portion CPU 111; a registration memory 112 registering the ID of a using permission-granted user; and the scanner portion control CPU 11 causing a copiable state only when a received ID coincides with registered ID.
