Abstract
PURPOSE: To provide a camera which permits lens interchanging and collapsible barrel by passing a lens barrel in a light shading plate which is held open at the lens mounting while sliding the same with respect to the mounting part at the time of mouating a lens to the camera body then collapsing the same.
CONSTITUTION: When an interchangeable lens 1 is mounted to a camera body 9, the shutter operating lever 7 on the interchangeable lens 1 side is in the position shown by the alternate long and two short dashes line. Since the mounting part 5 of the lens 1 and a lens barrel 4 are engaged with each other under moderate frictional force, the lens barrel 4 turns clockwise together with the mounting part 5, and the shutter operating lever 7 mounted to the lens barrel 4 turns clockwise as well and engages a U-shaped shutter driving lever 8. When the projection provided to the mounting part 5 of the lens 1 presses the contact part 24 of the lever 21 downward, the lever 2 assumes the state of the alternate long and two short dashes line, thereby turning a cam plate 18. As the cam plate 18 turns, six sheets of light shielding plates 16 are divided above and below and retreat from the optical path face, thereby opening the optical path to the film plane.
