摘要：An optical encoder includes a scale having bar-like scale marks; a detectionhead having a light source fiber emitting coherent light at the scale and a photoreceiverfiber receiving light reflected off the scale; electronic components connected to thedetection head via the light source fiber and the photoreceiver fiber; and a protector

covering the scale marks at a predetermined distance from the scale marks. Theprotector is a member configured with light-transmissive material and includes a topsurface that is inclined with respect to a principal surface of the scale.
