A remote controller detects an ON state or an OFF state of operation of pushing a remote controller key 2. When the detection result is the ON state, the remote controller generates a predetermined ON code S3 previously allocated to the remote controller key 2. When the detection result is the OFF state after it shows the ON state, the remote controller generates an OFF code S4 representing the OFF state, generates a transmission command by adding the OFF code S4 to the ON code S3, and then transmits the transmission command to a target command receiver. Therefore, the receiver can correctly recognize the contents of the transmission command S5 generated at the remote controller by detecting the OFF code S4. That is to say, the receiver can recognize the contents of the pushing operation of the remote controller key 2.
