Contactless power supply and data communication device, and system having rotation-drive unit, using same

A contactless power supply and data communication device comprising:

• a mechanism having a rotation part rotating by a motor and a fixed part facingly spaced apart from the rotation part, the rotation part and the fixed part being paired to each other;
• a first printed circuit board located on the rotation part;
• a first ferrite core located on the center of one surface of the rotation part on top of the first printed circuit board;
• a first coil wound onto the first ferrite core in such a manner as to be in parallel to one end surface of the first ferrite core and to allow both end portions to be connected to power input terminals of the first printed circuit board;
• a first optical communication module located on the first printed circuit board in such a manner as to be exposed to a hollow portion formed on the first ferrite core;
• a second printed circuit board located on the fixed part to receive external power;
• a second ferrite core provided on the second printed circuit board to face the first ferrite core;
• a second coil wound onto the second ferrite core in such a manner as to be in parallel to one end surface of the second ferrite core which faces one end surface of the first ferrite core and to allow both end portions to be connected to power output terminals of the second printed circuit board;
• and
• a second optical communication module located on the second printed circuit board in such a manner as to be exposed to a hollow portion formed on the second ferrite core that is extended in the form of a hollow portion of a linear pipe from the hollow portion of the first ferrite core.
