摘要： A light-reflective type rotary encoder used to measure the rotational frequency of a rotating shaft, the distance travelled by a sliding body, or other physical quantity has a casing body in which a rotor is rotatably held. Two input optical fibers laid parallel to each other and an output optical fiber laid between the input fibers are held in the casing body in such a way that each one end of these fibers is arranged in line and opposed to the fringe of the rotor on which reflective areas and non-reflective areas are alternately formed at regular intervals circumferentially. The other ends of the fibers which are disposed on the open end side of the casing body are surrounded and covered by a device-mounting case which is detachably mounted to the casing body and which holds a light-emitting device and light-receiving devices therein.

摘要： A rotary encoder used for measuring the rotational velocity, for example, of a rotating disk provided with reflecting surfaces and non-reflecting surfaces which are formed alternately on its periphery with a pitch l. The encoder includes one output optical fiber and two input optical fibers. All of the fibers have their one end surfaces opposed to the periphery of the disk. The input fibers are attached to the opposite sides of the output fiber in side-by-side relation. The interval between the end surfaces of the input fibers is set equal to l (n.+-.1/4), where n is a positive integer. Light-emitting devices connected to the input fibers produce output waveforms that are 90 degrees out of phase.

摘要： An optical rotary encoder eliminates the necessity of relatively positioning a code plate and a click mechanism therefor so that it can be assembled with ease. The code plate is mounted for rotation relative to a stationary plate member, and the click mechanism including a ball and a spring plate is interposed between the code plate and the plate member so that all the members can be incorporated as a single device.
