Abstract
A wiping device includes a roll unit, a moving member, processing circuitry, and a groove. The roll unit includes a band-shaped member, a first axial member, and a second axial member. The band-shaped member is wound around the first axial member to form a feed-side roll, and is wound around the second axial member to form a winding-side roll. The first axial member is movable relative to the second axial member. The moving member slides the roll unit. The processing circuitry controls sliding of the roll unit. The groove supports the first axial member at a position substantially horizontally opposed to the second axial member when a diameter of the feed-side roll is equal to or larger than a size, and guides the first axial member so that the first axial member moves upward and farther away from the second axial member as the diameter of the feed-side roll decreases.
