ABSTRACT:
A lens shutter mechanism for camera includes a shutter opening/closing lever which opens or closes a shutter blade or blades. The lever is pivotally mounted on a movable shaft which is fixedly mounted on a shutter close lever. At the same time as an electromagnet, which is used to maintain the shutter open, is deenergized, the shutter close lever is operated to cause the shutter opening/closing lever to close the shutter blade or blades.
