PROBLEM TO BE SOLVED: To provide: a radio transmitter which can be activated even with a feeble mechanical energy input to a power-generation element because it is arranged so that an output voltage of a booster part can be supplied to a timer; and a radio transmission system.SOLUTION: A radio transmitter 1 of the present invention, comprises: a rectifying part 2 operable to convert an electric power supplied from a power-generation element 100 form an alternating current to a direct current; a power-storage part C1 operable to storing an electric power from the rectifying part 2; a booster part 3 operable to boosting the electric power thus stored; a radio transmitting part 9 operable to execute a radio transmitting action, utilizing an electric power supplied from the booster part 3; and timer 6 for driving the booster part 3 at intervals of a predetermined time. The radio transmitter 1 is arranged to supply, of a voltage V1 of the power-storage part C1 and an output voltage V2 of the booster part 3, a higher voltage to the timer 6.SELECTED DRAWING: Figure 2 |
