Abstract

PURPOSE:To prevent erroneous instruction and malfunction to be left by detecting the condition of a controlled device main body with an instruction output signal from a remote control device and outputting a response instructing signal to the remote control device. CONSTITUTION:The condition of a mechanism 5 of a main body device A, which is controlled by instruction output data from a remote control device B, is detected by a mechanism detecting circuit 6 and outputted to a detecting data outgoing circuit A7. The outgoing circuit A7 converts detecting data to a format, which is determined in advance, and obtains it as the response instructing signal. Then, an infrared ray is caused to be a carrier and transmitted to a receiving circuit B8 of the remote control device B. The response instructing signal is converted to response instructing data by the receiving circuit B8 and outputted to a comparing deciding circuit 9 and the comparing deciding circuit 9 compares the instruction output data of an outgoing circuit B2 and the response instructing data of the receiving circuit B8. When the both data are coincident, a confirming tone is generated. In case of discord, a warning tone is generated and each tone is displayed to a display 10.
