Non-contact electric power feeding system has indicator which notifies state of non-contact electric power supply, allowing user to know presence or absence of receiving device or existence of foreign materials through lighting of LEDs

摘要

The non-contact electric power feeding system has an indicator (25) which is provided in the surface of a housing, and comprises the shell-type LEDs (27a-27d,28a-28x). A user is notified of the state of an electric power feeder through the indicator. The indicator notifies the state of the non-contact electric power supply, allowing the user to know the presence or absence of a receiving device in the electric power feeder or the existence of foreign materials between the feeder and the receiving device through the lighting of the LEDs.
