To solve the problem that a light signal from a light-emitting section in a remote control operating section is not often received by a light-receiving section on the main body side excellently according to the circumstances of toilet environment such as the states of installation of the main body section of a sanitary flushing device and the remote control operating section, or an obstruction such as a shelf and a vase in a toilet or the quality of materials or the like of a ceiling, a wall and a floor, on which the reflection of the light signal is assumed, and the sanitary flushing device cannot be operated substantially in this case.

In the remote control operating section transmitting a signal regarding command contents, a receiving section receiving a remote control signal transmitted from the remote control operating section and the sanitary flushing device conducting fixed operation to the remote control signal received by the receiving section, the receiving section is constituted so as to be able to be moved to the main body section of the sanitary flushing device.
