Abstract

PURPOSE: To make it possible to detect independently pieces of information on a rotation position and straight advance position, by using a combination of a cylinder, provided with light transmissive parts or reflective parts patterned in a fixed shape and arrayed at even intervals, slit plates, and light-source and photo detector.
CONSTITUTION: Cylinder 1 is provided with slit plates 19 and 20 for generating straight-advance position signals, slit plates 22 and 23 for generating rotation position signals, and light-source and photo detectors 21 and 24 correspond-them. Through slits 20 and 23, the straight-advance position signal and rotation position signal can be generated by photo detectors 21 and 24 respectively being independent of each other even if cylinder 1 is put in axial straight advance motion and cylinder- directional rotation motion at a time.
