Abstract
A conveying apparatus includes a conveyor roller, an angular velocity detection device, and a rotation angle calculation device. The conveyor roller conveys a conveyance object by a rotation thereof. The angular velocity detection device is provided to one of the conveyor roller and a rotating portion rotating with the conveyor roller such that an angular velocity detection axis is parallel with a rotation shaft of the conveyor roller. The rotation angle calculation device calculates a rotation angle of the conveyor roller based on an angular velocity detected by the angular velocity detection device.
