  "textContent": "In a non-contact electric power transmission system that electrically charges a device in a non-contact fashion, a transmitting circuit of a contact-less power transmitter includes both an excitation element and a resonance element, both corresponding to one of storage pockets, and transmits electric power from a specified storage pocket under a control signal from a transmission controller. At this time, the transmission controller, upon insertion of an obj ect being detected in a storage detector, uses information from an output detector to determine the object to be a destination device to which the power is to be transmitted, and controls the corresponding transmitting circuit to transmit the power. For example, the information from the output detector includes either a transmission rate associated with contact-less power transmission, or a differential between a load modulation period of the contact-less power receiver and that of the contact-less power transmitter. In addition, the transmission controller acquires charge information on the contact-less power receiver inserted in one of the storage pockets and controls the power transmission of the transmitting circuit. This simplifies a structure of the device to be charged in the contact-less power transmission system for non-contact device charging, and reduces the device in dimensions and weight.",
