Abstract

An automatic toilet flushing system which detects when a user sits on the toilet for use and, instead of operating a flush handle for flushing, performs flushing in association with the user's action of standing up to leave the toilet. A forced flushing sensor is also provided so that water can be flowed for flushing through deliberate action of the user.
