Abstract
A measuring instrument comprising an extensible member and a determining apparatus is provided within an electronic digital scale, said extensible member including sprocket holes arranged at a predetermined interval and said determining apparatus measuring the movement of the extensible member through the use of a movement recognition device. The movement recognition device includes a detection plate for rotating in unison with the movement of said extensible member. The rotation of the detection plate is sensed to generate a length information which is introduced into a computation circuit, whereby a measured result is displayed in a digital display arrangement.
