Abstract

PURPOSE: To accurately read the feed quantity of the feed screw of a machine tool, by accurately operating an encoder to digitally indicate the feed quantity.
CONSTITUTION: The tubular part 22a of a rotary member 22 is fitted on a casing 8 so that the tubular part cannot be moved in the axial direction but can be rotated. A slitted plate 32, which is a movable part of an encoder, is attached to the rotary member 22. A light projector 18 and a light receiver 20, which are fixed parts of the encoder, are mounted to face the rotation loci of the slitted plate 32. A casing 8 is removably mounted at an optional angle on the body of a machine tool. When a handle 50 is revolved, a feed screw 4 is rotated. At the time, the slitted plate 32 is rotated in connection with the rotation of the rotary member 22 and a signal from the light receiver 18 is processed by an integrated circuit in a casing 44 to perform digital indication on a display unit 16.
