<p>PURPOSE:To transmit many signals by forming a capacitor of an electrode provided at a steering wheel and an electrode at a bearing side, and coupling mechanically an oscillation circuit and a signal generating circuit in contactless state. CONSTITUTION:One electrode 31 constituting the capacitor 3a is connected to an input of an inverter 21a with a resistor 23 of the oscillation circuit 2 and one end of a capacitor 24 and the other electrode 33 is connected to one end of resistors 12a-12e connected in parallel in the signal generating circuit 1. Further, the electrode 32 constituting the capacitor 3b is connected to the output of an inverter 21b and the other electrode uses the electrode 33 in common. In closing selectively switches 11a-11e of the circuit 1, the frequency of output signal of the circuit 2 is changed.</p> |
