<p>PROBLEM TO BE SOLVED: To shorten operating time and save electric power. SOLUTION: This identification signal collating device has a detected device 1 having a transmitting means 4, a signal processing means 3 with a memory part 3a, a reloadable storage means 5 for storing individual identification signals, and a power switch 2. When the power switch 2 is closed, the individual identification signals stored in the storage means 5 are read-out and written in the memory part 3a of the signal processing means 3 for signal processing. Special authentication signals SID are set to the individual identification signals, and the special authentication signals SID are stored in the storage means 5 and the memory part 3a of the signal processing means 3 together with the individual identification signals. When the special authentication signal SID from the storage means 5 is equal to the special authentication signal SID stored in the memory part 3a of the signal processing part 3 at the time of closing the power switch 2, the individual identification signal is not written in the memory part 3a of the signal processing means 3.</p> |
