Patent ID: 7518957

Claim:
A time-data transmitting apparatus comprising: a time-measuring portion which measures current time data; a radio-wave reception control portion which receives a standard-time radio wave signal containing time data; a time-correcting portion which corrects the current time data measured by the time-measuring portion based on the time data contained in the standard-time radio wave signal received by the radio-wave reception control portion; a transmission-demand signal reception control portion which receives a weak-wave transmission-demand signal; and a transmission control portion which transmits a radio wave containing time data based on the current time data measured by the time-measuring portion, at a predetermined time and at a first intensity, and which, for a predetermined time period, halts transmission of the radio wave containing the time data at the first intensity and performs transmission thereof at a second intensity that is lower than the first intensity, when the transmission-demand signal reception control portion receives the weak-wave transmission-demand signal.
