Abstract

PURPOSE: To display the length of a measured long material in digital exactly and to extend the life of device by using a magnetic substance for the base material of the sliding measure and by providing a nonmagnetic substance layer of a fixed thickness on the surface of base material at regular intervals.
CONSTITUTION: The nonmagnetic substance layers 3 of a fixed thickness are arranged on the circumference of the linear magnetic base material 2 at regular intervals, the surface of layer is coated with resin 4. The sliding measure 1 is wound around the drum 6, the magnetic detector 7 produces a pulse every time the base material runs in front of the detector, its count value is digitally displayed by the indicator 8.
