PURPOSE:To obtain a wireless controller device equipped with a function to transmit required data only at need. CONSTITUTION:Memory 13, 15 and comparators 14, 16 are provided at both a receiver side and a transmitter side. Key data outputted from a key input part 1 is updated and stored in the memory 13 on the transmitter side at every input of data. The comparator 14 on the transmitter side outputs the key data outputted from the key input part 1 only when the key data stored in the memory 13 is different from that outputted from the key input part 1. The comparator 16 on the receiver side stores received key data in the memory 15 when the received key data is different from the key data stored in the memory 15. The key data stored in the memory 15 is outputted from a data transfer circuit 9 corresponding to a data request signal from the outside. |
