Abstract: The present invention is intended to provide a contactless power supply and data communication apparatus comprising: a main shaft configured to connect and fix an upper combination body from the center while being supported by a lower combination body; a motor configured to provide rotation power for rotating a rotary part centering around the main shaft; a wireless power part consisting of a transmission part core united with and fixed to an outer circumferential surface of the main shaft, and a reception part core spaced apart from the transmission part core, and rotating from an upper end, thereby supplying and receiving power through electromagnetic induction; and an optical communication part configured to transmit and receive an optical signal by being configured in such a manner that a rotary communication element disposed on a lower surface of a rotary substrate rotating with the main shaft as its center, and a fixed communication element disposed on an upper surface of a fixed substrate which is fixe

Abstract: A contactless power supply and data communication device has a rotation part and a fixed part formed as a pair, the rotation part rotating by a motor, and the fixed part being spaced apart from the rotation unit by a predetermined distance, receiving external power, and fixedly operating, wherein the rotation part and the fixed part each include: a ferrite core having a hollow-ring-shaped inner through hole; a control board for fixing the ferrite core at the center and carrying out a control function; and an optical communication module positioned at the center portion of the control board, and by means of such configuration, power is supplied to the rotation part by means of the electromagnetic induction of power which is supplied to the fixed part, and the rotation part and the fixed part carry out data communication by means of the optical communication modules using infrared rays, etc.
