A wireless transmitter device (10) has a predetermined upper limit of an accumulated data transmission time per predetermined duration corresponding to a predetermined maximum value. The wireless transmitter device (10) includes a timer (20) which starts keeping time when the wireless transmitter device (10) sends a wireless signal and stops when it reaches a timeout value, a total transmission time measurer (18) for measuring the data transmission time of the wireless transmitter device (10) during a period from the timer (20) starting to stopping, and a transmission controller (22) for refraining the data transmission at the earliest until the time being measured by the timer (20) reaches the timeout value if the accumulation time is, or likely to be, equal to or larger than a threshold value. |
