PURPOSE:To enable a level detector with stable performance to be incorporated in a relatively thin discharge pipe by providing a prism and the level detector formed of light emanating and receiving elements opposed to this prism in a chamber for receiving an end of a discharge hose. CONSTITUTION:A level detector 32 provided in a receiving chamber 29 is provided with a prism 33 located slightly above a inflow port 30 and having the end cut conically and light emanating and receiving elements 34, 35 opposed to the prism 33 on the upper surface of the prism 33. Light projected from this light emanating element 34 is relfected directly from the 45 deg. mirror face of the prism 33 and received by the light receiving element 35 which generates the output signal.
