Abstract
A belt device includes a belt assembly, a pressing force adjuster, and an optical sensor. The belt assembly includes multiple rollers and a belt stretched by the multiple rollers and is rotatable about a rotation axis of one of the multiple rollers. The pressing force adjuster rotates the belt assembly about the rotation axis and adjusts a contact pressure of the belt pressed against an object. The optical sensor is disposed opposite to the one of the multiple rollers, and a position of the optical sensor relative to the rotation axis is fixed while the belt assembly is rotated by the pressing force adjuster.
