In a non-contact electric power transmission system that electrically charges a device in a non-contact fashion, a transmitter includes excitation and resonance elements, and transmits power from a specified storage pocket under a control signal from a transmission controller. The transmission controller, upon insertion of an object being detected, uses information from an output detector to determine the object to be a destination device to which power is to be transmitted, and controls the corresponding transmitter circuit to transmit the power. The information from the output detector can include a transmission rate, or a differential between a load modulation period of a receiver and that of the transmitter. The transmission controller acquires charge information on the receiver inserted in one of the storage pockets to control the power transmission. This simplifies the device to be charged for non-contact device charging, and reduces the device in dimensions and weight.
