Filed: 1994-12-23
Abstract: PURPOSE: To identify a regular transmission signal by providing the output of a coincidence signal when a fixed code included in a received signal is coincident with a regular fixed code and the included variable code is of an additive type and over a reference variable code and using a code being the sum of 1 and the received variable code for a succeeding reference code. CONSTITUTION: Upon the receipt of an infrared ray signal, a receiver 2 converts it into an electric signal and collates its fixed code with a regular fixed code stored in advance in an E<2> PROM 13. When the code is discriminated to be a regular code, a variable code in the signal is collated with a reference variable code obtained by applying addition processing to the regular code received precedingly. When the fixed code of the signal received this time is coincident with the regular fixed code and the variable code is of an additive type and more than the reference variable code and the difference has a prescribed relation, a coincident signal is outputted to a door lock device 14 and the variable code is stored in the E<2> PROM 13 as the reference variable code. Thus illegal transmission is surely excluded.
