Abstract

PURPOSE: To rapidly and automatically open a shutter which prevents the counter- incident light by opening an eyepiece shutter while being interlocked with the winding action.
CONSTITUTION: After having photographed, winding lever 11 is rotated to wind up, and transmitting member 15 is moved to the right. Thus, operating lever 4 is depressed to rotate the lever anticlockwise. When shutter is operated, the eyepiece lens 2 is interrupted by the eyepiece shutter 1 in order to prevent the counter- incident light. Then the eyepiece lens 2 is automatically opened by the shutter 1 as soon as winding-up is completed. The shutter of the eyepiece lens can be easily and quickly opened by this automatic operation wherein the manual operation is no lenger required, hence the photographing speed can be increased
