Belt supporting roll, and belt rotating device and processing system including belt supporting roll

Abstract

A belt supporting roll configured to support an endless belt while allowing the belt to rotate includes: a roll body around which the belt is to be wrapped; a holding component extending in an axial direction of the roll body and holding two ends of the roll body while allowing the roll body to rotate; and a supporting component provided at a lengthwise central part of the holding component and supporting the roll body and the holding component while being movable. The supporting component has a range of motion containing a first directional component and a second directional component. The first directional component intersects a bisector of a central angle of an angular range by which the belt is to be wrapped around the roll body. The second directional component is parallel to the bisector.
