MONITORING DEVICE WITH RADIO TIMEPIECE

摘要

PROBLEM TO BE SOLVED: To accurately maintain the time of a built-in timepiece, and at the same time to eliminate the need for a backup battery for compensating for power failure. SOLUTION: A monitoring device 1 for recording monitoring based on the time of a built-in timepiece 12 is provided with a standard radio wave reception antenna 10, a standard radio wave reception circuit 11 for obtaining standard time information from a standard radio wave being received by the standard radio wave reception antenna 10 for outputting, a decode part 13a for obtaining the standard time based on the standard time information being outputted by the standard radio wave reception circuit 11, and a time correction part 13b for correcting the time of the built-in timepiece based on the standard time being obtained by the decode part 13a.
