Abstract

PURPOSE: To display the length of a measured long material in digital exactly and to extent the life of device by using a magnetic metal for the sliding measure and by providing slits in the measure at regular intervals.
CONSTITUTION: The slits 3 are provided in the magnetic metal tape 2 at regular intervlas, the surface of slit is coated with resin thin film. The sliding meausre 1 is wound around the drum 7, the magnetic detector 8 produces a pulse every time the slit runs in front of the detector, its count value is digitally displayed by the indicator 9.
