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： A magnetic encoder is provided, in which a large output voltage (a large amplitude) is obtained so that the magnetic encoder can have a strong resistance to external noise and so that malfunction can be prevented.Each of first to fourth magnetoresistance elements A1, A2, A3, and A4 has at least a pinned layer, and a free layer in which an internal magnetization direction changes in accordance with external magnetic fields emitted by a magnetic body 11. A magnetization direction α of the pinned layer is set to be in a first direction (a direction Z2) that is parallel to an outer peripheral side surface 11A and that is perpendicular to rotation directions ra1-ra2, or is set to be in a second direction (a direction Z1) that is opposite to the first direction. Additionally, an initial magnetization direction β of the free layer is set to be in the first direction (the direction Z2) or the second direction (the direction Z1). When a pitch of N and S poles adjacent to one another in the rotation direction is denoted by λ, a pitch of the magnetoresistance elements A1, A2, A3, and A4 is set to a pitch of λ/2.
