PURPOSE:To transmit a securer instruction signal and to make the instruction, which can be transmitted, more complicated by converting the instruction inputted by an operator to an electric signal, sending to a controlled equipment, displaying a receiving signal from the controlled equipment visually and converting to an alarm sound. CONSTITUTION:When an operator inputs an instruction from an instruction input part 1 of a remote control transmitting device 20, the instruction is sent to a control part 4, thus, the control part 4 goes to be a transmitting mode, sends a signal to a transmitting part 2 and makes a receiving part 5 into an action condition. A controlled equipment 30 immediately transmits a receiving signal B to show that a transmitting signal A is received. When an additional block 6 has a display part having a display function, the display of the transmitting completion appears at the display part in accordance with the signal sent from a transmitting completion mode control part 4 to the display part. When the transmitting mode is released while the receiving signal B is not returned, the display is executed which indicates the impossibility of transmission. |
