    Abstract: A liquid delivery nozzle to be used in gasoline stations comprising two pairs of light sensor in which the first pair arranged at the tip end of the nozzle is of reflection type and the second pair arranged a little higher up from said first pair is of usual contact type, for more relevantly coping with full tank delivery. The sensors are mounted in a casing which is to be mounted on the nozzle inner wall surface near the tip end. In order to prevent leads extending through said nozzle and a hose connected therewith for angular movement from being damaged due to such angular movement, a flexible sheet on which leads are printed or embedded, has a part wound to form several spiral turns. The sheet is arranged in the portion where angular movement occurs to cope with such movement by loosening or tightening of the spiral turns.
