Abstract:
To clean a cleaning object surface following movement of an optical filter without providing a special actuator.SOLUTION: A first filter frame 18 can move in a guide direction by a rear lens barrel 6 in a state of holding an infrared cut filter 23, move in a direction substantially orthogonal to an optical axis of an imaging optical system, and insert or retract the infrared cut filter 23 to/from an optical path. A first cleaning member 51 is attached to the first filter frame 18 so as to protrude to a side of an image pick-up device 27 in an optical axis direction. A surface of the image pick-up device 27 is a cleaning object surface becoming an object of cleaning by the first cleaning member 51. The first cleaning member 51 cleans the cleaning object surface with movement while being brought into contact with the cleaning object surface following movement of the first filter frame 18.SELECTED DRAWING: Figure 4
