Abstract: An encoder includes a disc and a sensor. The disc has a circular surface with a central axis and is rotatable around the central axis. The disc has a slit row provided on the circular surface. The slit row includes slits arranged in a circumferential direction of the circular surface around the central axis and in a radial direction of the circular surface. The sensor is provided opposite to the slit row on circular surface. The sensor has a first light receiver and a second light receiver. The first light receiver is configured to output a first light receiving signal as the slit row rotates along the circumferential direction when the disc rotates around the central axis. The second light receiver is configured to output a second light receiving signal as the slit row moves along the radial direction when the disc rotates around the central axis.

Abstract: Reflected light can be effectively utilized by increasing a light receiving area. Incremental light receiving element groups are separated and arranged in the circumferential direction of a rotating unit while placing a light source therebetween. First and second absolute light receiving element groups are arranged at both sides of the outside and inside of the light source in the radial direction of the rotating unit. As a result, first and second absolute light receiving elements are continuously arranged, and also the incremental light receiving element groups and the absolute light receiving element groups can be arranged to surround the periphery of the light source from four directions.
