Abstract:
An optical scanning device includes a housing, a transmissive member, a wire-shaped member, a driving portion, a cleaning holder, a cleaning member, a stopper, and a control portion. The control portion is capable of executing a cleaning mode including at least one of a forward travel operation of controlling the wire-shaped member to travel in a first direction so that the cleaning holder moves along the transmissive member and a backward travel operation of, after executing the forward travel operation, controlling the wire-shaped member to travel in a second direction so that the cleaning holder moves in an opposite direction to a direction of the forward travel operation. The control portion executes a load releasing operation of controlling the cleaning holder to move by a prescribed amount in an opposite direction to the direction of the forward travel operation or the direction of the backward travel operation.
