Abstract

PURPOSE:To permit to facilitate discrimination of a scope of spin overlap occurring at a time when turning by 360 deg. or more and to enable detecting of an absolute angle, by a method wherein, in an angle detector, a cam, which slides over a fixed shaft following rotation, is mounted. CONSTITUTION:A fixed shaft 2, fabricated with an outer peripheral thread, is secured to a case 1. Rotary discs 3 are rotatably attached to the fixed shaft 2 through bearings 4, and the discs 3 at both sides are coupled to each other with a coupling rod 5. A cam 6, screwing the fixed shaft, has a projection part 6a with a rotary angle of 90 deg. at the outer periphery, and the coupling rod is inserted into a circle hole 6b. CCW switches 7 and 8 make contact with the projection part. If the rotary disc turns from -270 deg. to +270 deg., the cam moves from A to G. In a scope AB covering -270 deg.--180 deg., the switch 7 actuates, and in a sphere covering +180 deg.-+270 deg., the switch 8 works, which results in enabling to discriminate which overlap spin scope the cam is brought to.
