Abstract
According to one embodiment, a reference member cleaning device used in an optical detection unit causes a driving module to convey a reference member and to rotate a wipe-off member. The reference member cleaning device of the optical detection unit transmits the power of the driving module to both the wipe-off member and the reference member, in such a manner that the rotating direction of the wipe-off member and the conveying direction of the reference member are reversed at the position where the wipe-off member and the reference member come into contact with each other.
