ABSTRACT:
A photographic exposure apparatus includes an exposure lens, a lens carriage having a light shield region and a lens mount region, and a device to move the lens carriage selectively to a position with the lens extending across an axis of exposure light. A first shutter controls the exposure light. A second shutter prevents the exposure to scattered light. A mechanical linking device is responsive to the movement of the lens carriage to close and open the second shutter. When the lens on the lens carriage is dislocated from the axis of exposure light in a standby mode, the mechanical linking device closes the second shutter to interrupt scattered light. When the lens extends across the axis of exposure light in an exposure mode, the mechanical linking device opens the second shutter.
