When the data such as country name, zone name, area name, date and time are corrected as described above, the LCD 22
Is externally displayed (S2-7), and the imprinting LED 33 is turned on to enable imprinting of data as described above.

Of course, when the correction is unnecessary (NO in S2-1), the previously determined data is not corrected, and the display of the LCD 22 and the imprinting by the imprinting LED 33 are performed based on the data. become.

FIG. 4 is a flow chart of time correction.
At all times, the clock is counted up every 0.5 seconds or 1 second (S3-1), for example, at 12:00 midnight (YES in S3-2), the standard time detection means 25 sets the standard time signal to the reception level. If (YES in S3-3), the standard time signal is received and the time data is corrected (S3-4).
