Abstract
An imaging-device cleaning apparatus is attached to a camera by engaging with a lens mount of the camera typically used for attaching a camera lens. The imaging-device cleaning apparatus includes a nozzle for removing dust and dirt in the vicinity of an imaging section of the camera, and a motor and a fan for supplying air to the nozzle to remove the dust and dirt from the vicinity of an image sensor of the camera.
Claims1
A camera on which a cleaning apparatus can be removably attached thereto, the cleaning apparatus cleans an image sensor of the camera, the camera comprising:
- a mount for detachably supporting the cleaning apparatus;
- a signal terminal that electrically connects to the cleaning apparatus supported by the mount;
- a shutter unit that alternately travels between an open state where the object light reaches the image sensor and a closed state where the object light does not reach the image sensor;
- and
- a control unit that controls the shutter unit,
- wherein the control unit travels the shutter unit to the open state, when receiving a first signal transmitted from the cleaning apparatus supported by the mount via the signal terminal, and transmits a second signal to the cleaning apparatus via the signal terminal after the shutter unit is traveled to the open state.
