ABSTRACT:
A camera with a focal plane shutter is provided with a device for indicating the completion of the winding of the shutter. The indicating device is a spring biased lever having one end which engages a metal blade or blade driving member of the shutter when the shutter is wound to rotate the lever against the biasing force of the spring. Under this condition a red portion of the other end of the lever is viewable through a window in the camera body. When the shutter is released, the metal blade or blade driving member moves to a retracted position allowing the lever to rotate under the biasing force of the spring. As a result a black portion of the other end of the lever is viewable through the window.
