The driving apparatus includes: driving unit driving driven unit; controller controlling the driving unit; portion to be detected in which first areas and second areas are arranged alternately; and detector that detects the first and second areas. The portion includes, on one side of base position in a moving direction, first areas having small width and second areas having different widths larger than the first areas on the one side, and includes, on the other side, second areas having small width and first areas having different widths larger than the second areas on the other side. When moving the driven unit to specific position, the driven unit is driven in direction determined according to an area detected by the detector when starting the operation, and reverses the direction if the driven unit is moved by a predetermined amount or larger in the area after the detection area is changed. |
