Abstract
A device having a movable belt for transporting, for example, a recording medium, at least one rotary body around which the belt is wound so as to be supported thereon, and limiting portions or members for limiting the movement of the belt in the axial direction of the rotary body. The device is designed to stabilize the movement of the belt by making the friction between the limiting members smaller than the friction between the belt and the rotary body.
