Abstract

PURPOSE: To make possible automatic fading by changing over and operating an aperture member from a high speed to a low speed upon lapse of a fixed time after fade-in start.
CONSTITUTION: In the case of performing fade-in photographing, it is accomplished by turning an operating member clockwise to the fade-in photographing position and turning a main switch SW0 ON. By this operation, a fade-in start switch SW3 is turned ON. As the switch SW0 goes ON, an aperture member 10 is operated up to close at a high speed and when the switch SW3 goes OFF, the aperture member 10 is opened at a high speed. Along with this operation, charging of a capacitor C0 takes place and the third comparator COM3 inverts, causing a monostable multivibrator to become operating. From this point, the aperture member 10 is operated up to the correct exposure aperture value during the time determined by the monostable multivibrator.
