INPUT/OUTPUT DEVICE AND REMOTE CONTROLLER

摘要

An input/output apparatus is provided which is capable of preventing electric shock without reinforcing the insulation of a power-supply unit and capable of connecting to a USB, a LAN, or the like. An input/output apparatus 2 includes a power-supply circuit 26 that uses electric power as the power supply of the present apparatus 2, which is generated in a resonance circuit 27 by an induction of an AC magnetic field from the resonance circuit 17 on the apparatus main body 1 side, and a communication circuit 24 that transmits and receives a signal between a resonance circuit 25 of the present apparatus 2 and a resonance circuit 15 on the apparatus main body 1 side, and capable of being insulated from the power supply of the apparatus main body 1 by receiving electric power from the apparatus main body 1 in a non-contact state and by communicating with the apparatus main body 1 in a non-contact state, thereby.
