PROBLEM TO BE SOLVED: To prevent dust, or the like, from infiltrating a camera body due to replacement of a lens. SOLUTION: When a lens unit 20 is attached to a mount 12 and power supply of a lens interchangeable digital camera 1 is turned on, the lens unit 20 is locked so that the unit 20 cannot be detached from the mount 12, and an AF motor unit 43 is driven to actuate a compressor 42. The compressor 42 generates compressed air, by using air supplied through an air filter 41 and supplies it to an air jetting unit 48 through an air duct 47. The air jetting unit 48 jets the supplied clean compressed air to space surrounded by a cover 40 and a lens mount 22. Thus, dust or the like adhering to the inside of the space surrounded by the cover 40 and the lens mount 22 is blown away. COPYRIGHT: (C)2010,JPO&INPIT |
