Abstract

PURPOSE:To make construction simple and control easy by pivotally fitting an opening driving lever above a closing driving lever in a shutter serving also as a stop. CONSTITUTION:Shutter blades 3a, 3b are driven by pinching of a shutter opening and closing lever 5. When a motor is turned by release operation, a pin 6 is guided by the cam 7a of a gear 7, and the lever 5 is swiveled right around a shaft 9, thereby beginning to open the blades. When correct exposure is obtained, an electromagnet 12 is de-energized by the signal from a control circuit 26, and a closing lever 10 is swiveled right around a shaft 27. At this time, the lever 5 swivels left around the pin 6, thereby closing the blades. Upon ending of the exposure operation, the motor runs reverse and resets the lever to the original position and this eliminates the need for charging operation. In the case of using this for an aperture priority type, the use of a detector such as a comb-toothlike conductor 24 suffices.
