1. A power-receiving-module-type telemeter transmitter of a telemeter measuring system disposed in a rotor and that performs communication using power received from a power transmitting antenna formed in an arc shape on a stator, the power-receiving-module-type telemeter transmitter comprising:
three or more power receiving modules disposed in the rotor at intervals in a circumferential direction;
a same number of OR circuits as the power receiving modules, wherein the OR circuits each output a highest voltage among voltages input from the power receiving modules;
the same number of sensors that each measure a state of a monitoring target and output measurement data indicating the state of the monitoring target; and
the same number of transmitting units that are each driven by the highest voltage from a corresponding one of the OR circuits as a power source and that transmit a radio signal including the measurement data of a corresponding one of the sensors, wherein each of the OR circuits is connected to two of the power receiving modules, and the transmitting units are respectively driven by first voltages input from the OR circuits as power sources.
