Abstract

PURPOSE:To imprvoe the positioning precision and make the whole of the constitution compact, by provding a magnetic scale for detection of a piston position, and/or a magnetism generating material and its reading head directly on a cylinder. CONSTITUTION:Known magnetic scale and reading head are used as a magnetic scale 16 and a reading head 17 of a piston position detector, and one end of the magnetic scale 16 is attached to a head cover 15, and the reading head 17 is attached to a piston 12.In this case, the magnetic scale 16 is entered into the reading head 17 and a cylinder 19 according as the piston 12 is moved, and the piston position detection signal due to the head 17 is taken out to the external. In this invention, many optional stop positions can be set, and the positioning precision is improved, and the whole of the constitution is made compact.
