Abstract

PURPOSE: To provide an automotive control information transmitter/receiver which can easily process increased number of information by employing memory cell having read only memory or the like of similar function thereto.
CONSTITUTION: When a vehicle element 1 approaches a ground element to electromagnetically couple the former with the latter, a positive feedback circuit having the element 1 and an amplifier 1a alters its characteristics to obtain the same frequency as the resonance frequency of the ground element. If this frequency is passed, for example, through a band pass filter 4a, the circuit produces its output "1" at its output terminal A. In this case, a full-wave rectifier 8 produces no output to thus cause the output at the output terminal M to become "1". If both the terminals A and M simultaneously become "1", these outputs "1" are applied to the inputs of a read only memory 21 through an address terminal Al to thus cause the inputs to terminals A2, A3 to become "0". Thus, predetermined data stored in advance are produced from the memory to a controller
