<p>PURPOSE:To omit an electrical cable for connecting an operating board to a control unit by subjecting the operating board on a steering wheel and the fixed control unit on a car to electromagnetic coupling by means of an electric coil. CONSTITUTION:An operating board 31 is held at rest on a steering wheel 31 via a group of gears 39, 42, 43a, 43b constituting planetary gears irrespective of the rotation of the wheel 31. And, electric coils PTL2 and STL2 are fixed on a supporting plate 39a fixed on a gear 39, and coils PTL1 and STL1 are fixed inside the operating panel 31 facing to said coils. With such constitution, the key operation information of the key operating board 31 is sent to and received by a control unit in the same way as a data transmitting and receiving process among usual telecommunication terminals, and hereby required machine control can be performed.</p> |
