Abstract

A control circuit of a remote controller includes a CPU, the CPU having a data memory adapted to store signal codes of different electric apparatuses. A procedure table memory adapted to record key switch functions of different electric apparatuses is included. A computing element is provided for sequencing through a plurality of the stored signal codes. A search interruption is included that is adapted to interrupt the sequential output of the signal codes when an output code is in conformity with a selected function of a particular electric apparatus. An emission output device is coupled to the CPU to transmit the signal codes to the electric apparatus.

Claims

1. A control circuit for a remote control device, comprising:

a key switch array for designating predetermined functions of an electrical apparatus selected to be controlled;

a processor having a plurality of first inputs coupled to said key switch array, said processor including (a) a data memory having signal codes of a plurality of different electrical apparatuses pre-stored therein, (b) a procedure table memory for storing a plurality of functions associated with said key switch array, (c) a computing element for sequential output of signal codes from said data memory responsive to a first momentary operation of selected keys of said key switch array, (d) a search interruption control coupled to said computing element for terminating said sequential output responsive to a second momentary operation of any key of said key switch array and storing a signal code being output coincidence with said second momentary operation of any key, and (e) timing means for controlling a rate of said sequential output of signal codes; and

,

an emission output device having an input coupled to said processor for transmitting said signal codes to the electrical apparatus.
