Abstract
PURPOSE: To make operation mechanism simple and production costs low by reciprocatively moving a cam member by means of a driving motor which can run forward and backward, thereby opening and closing shutter blades.
CONSTITUTION: The main parts of a lens shutter are constituted of a movable lens group 4, a stationary lens, two shutter blades 6a, 6b, a shutter opening-closing carm ring 7 as a cam member mounted to the immobile member 2 of the camera, and a driving motor 8 that can run forward and backward, for reciprocatively turning the cam ring 7. The cam ring 7 is so arranged as to turn reciprocatively when the motor 8 runs forward and backward. With such constitution, the opening and closing of the shutter blades are accomplished by the motor; therefore, the need for charging the shutter prior to releasing the shutter is eliminated, and the need for any charging mechanism consisting of a return spring, an electromagnet, etc. is eliminated, thus the mechanism is simplified.
