CORD SENDING REMOTE CONTROLER TO FACILITY OPERATING INDICATOR

摘要

The apparatus is characterized in that both terminals of a non-use key are connected to second and fourth transistors operated by the first and third transistors in a key matrix of a known remote controller having a microcomputer, a transistor, and a light emitting diode, in that amplifying part is connected to signal detecting parts for connecting a signal line, a buffer, and condenser to base terminals of the transistors, and in that the output of the amplifying part is provided to the base terminals of the transistors.
