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: A torque sensor includes: a strain body; and an optical sensor configured to detect a deformation of the strain body. The strain body includes an outer peripheral portion having a ring shape, and an inner peripheral portion of which at least a part is disposed inside the outer peripheral portion in a radial direction. The optical sensor includes a scale fixed to one of the outer peripheral portion and the inner peripheral portion, and disposed between the outer peripheral portion and the inner peripheral portion, and a detector fixed to a remaining one of the outer peripheral portion and the inner peripheral portion, and disposed to face the scale between the outer peripheral portion and the inner peripheral portion.
