Abstract
A fast-opening shutter includes an actuating member moveable in a one direction for setting an aperture stop and in the opposite direction for setting focus. The camera shutter is then driven to open against the stop independently of movement of the actuating member. According to more specific features, the actuating member first sets the stop and then focuses a camera optical element. After the exposure is completed, the mechanism is reset by further movement of the actuating member in the second or opposite direction.
Claims10
A camera mechanism including an actuating member moveable in a one direction for focusing an optical element and an opposite direction for controlling a shutter aperture according to a desired exposure value;
- characterized in that:
- said actuating member sets a stop for limiting shutter movement to a maximum aperture;
- and,
- said shutter is driven to open to said maximum aperture determined by said stop.
A camera mechanism including an actuating member rotateable in one direction for adjusting camera focus and rotateable in an opposite direction for controlling a shutter aperture;
- characterized in that:
- said actuating member controls said shutter aperture by setting a maximum aperture stop;
- and,
- said shutter is driven to open against said stop independently of movement of said actuating member.
A camera mechanism for setting the maximum aperture of a shutter and the focus of an optical element , said mechanism comprising:
- an actuating member;
- means for rotating said actuating member in a first direction for setting a stop that limits the maximum aperture of the shutter, and for rotating said actuating member in a second direction opposite said first direction for setting the focus of the optical element.
