Abstract: An encoder includes: an optical module that detects angular position information indicating an angular position of a rotating disk within one rotation thereof; a magnetic detecting unit that detects multi-rotation information indicating the number of rotations of the disk; a battery that supplies a power to the magnetic detecting unit when an external power is not supplied to the encoder; and a connector that connects connection terminals of the battery to a substrate to which at least one of the optical module and the magnetic detecting unit is connected, via solders in contact with the connection terminals.

Abstract: An encoder includes a rotating body that is rotatable around a rotation axis; a disk that is fixed to the rotating body and has a scale formed in a ring shape; an optical module that is disposed to face the disk and detects the scale; a first magnet that is disposed on one side from the disk in a direction of the rotation axis and fixed to the rotating body; and a first magnetic detector that is disposed on a remaining side from the disk in the direction of the rotation axis and detects magnetism of the first magnet.

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.
