To provide a small and low cost remote controller which can be operated in a non-contact manner.
A toilet seat device includes a body 200 which is arranged on a toilet bowl and incorporates a plurality of electric functions, and a remote controller 400. The remote controller 400 is provided with a contact switch 410 which is operated by contact or push, and a non-contact switch which has an illuminance sensor 440. The body 200 is provided with a seating detection sensor 250 which detects a body of a person seating on a toilet seat 220. When an operation signal of the non-contact switch is received, different electric functions are controlled based on a condition combining a detection signal of the seating detection sensor 250 and an operation signal of the contact switch 410, whereby non-contact operation of the plurality of electric functions can be performed by a small number of illuminance sensors 440 to reduce the number of used components and an installation space, which achieves a small and low cost remote controller.
