Abstract

PURPOSE: To prevent error-operation and detect an accurate liquid level by setting a liquid-level sensor formed to have non-light-permeability except for its conical surface in a storage with a vent hole.
CONSTITUTION: a liquid-level sensor 14 set in the end of a discharge hose has non- light-permeability and constitutes part of a hose. A sensor storage 1403 separated by a partition wall 1401 has a vent hole 1423, thus almost preventing an error- detection of the liquid level in a tank to be filled or error-operation. A prism 14 as non-light-permeable substance is formed to have non-light-permeability except for the conical surface of 45 degrees at its end and allows light in only through its conical surface of 45 degrees, thus almost excluding the error-operation due to the light from outside
