PROBLEM TO BE SOLVED: To simplify the mutual confirmation between a remote controller and a toilet device main body. SOLUTION: A remote controller 101 has an operating means 102 to be operated by a user, a time counter 201 for counting operation intervals, a transmission adding means 202 for adding the time data of the operation interval to the operation signal, and a transmitter means 105 for performing transmission. A toilet device main body 109 has a receiver means 108 for receiving the transmission signal from the remote controller 101, a time counter means 203 for counting the receive interval, and an operation means 204 for operating and comparing the transmission interval contained in the receive signal with the receive interval. In the only case where results of the operation by the operation means 204 coincide with each other, the main body drives a load in conformity with the operation data.
