Abstract:
A belt conveying device includes an endless belt stretched by a plurality of rollers; a drive unit that is connected to one of the plurality of rollers and drives the roller; a plurality of belt velocity detectors that are arranged at a plurality of locations along a belt width direction perpendicular to a moving direction of the endless belt and detect conveyance velocities of the endless belt; and a belt-inclination calculating unit that calculates an inclination of the endless belt in the moving direction from a difference between conveyance velocities of the endless belt detected by the plurality of belt velocity detectors.
