<p>PROBLEM TO BE SOLVED: To reduce the width of the entire device by locating a power transmitting winding and an information transmitting winding at right angles with each other to prevent the interference between a high frequency electromagnetic field caused by the power transmitting winding and that caused by the high speed information transmitting winding. SOLUTION: An information transmitting primary winding Wc is wound large to surround the outer surface of a high frequency magnetic rectangular core Cp and a power transmitting primary winding WP is wound small in the direction crossing at right angles with the direction of the winding axis of the information transmitting primary winding Wc. Then, the information transmitting primary winding Wc is connected to a high frequency modulator HM to communicate with a controller Co and the power transmitting primary winding WP is connected to a power supply. On one side of the high frequency magnetic rectangular core CP, U-shaped high frequency magnetic cores Cc1, Cc2,...CnN are arranged in the moving direction and the information transmitting secondary winding Wc2 is wound on the core Cc and power transmitting secondary windings WP2 are wound around three windings Np, Wc, Wc2 in the direction crossing at right angles with the winding axis of the information transmitting secondary winding Wc2. Then, a table is fastened to each of the U-shaped magnetic cores Cc1, Cc2,...CcN and the tables are moved linearly.</p> |
