Abstract: 1285723 Shutter diaphragms EASTMAN KODAK CO 28 Aug 1969 [28 Aug 1968] 42910/69 Heading G2A A programmed shutter has a pair of movably mounted vanes 11, 18 each having an aperture 12, 19 formed therein and co-operating to function as a shutter and an exposure aperture, the first vane 11 being pivotally mounted at 13 on a camera housing 25, and the second vane 18 being pivotally mounted at 23 to a linking member 20 which is pivotally mounted at 24 to the camera housing, the linking member and the first vane being interconnected via pin 21 and slot 22. Immediately prior to an exposure, Fig.7, a shutter release member 35 is biased by spring 41 to urge an ear 39 thereof into contact with an edge 11a of vane 11, and spring 42 extending between member 35 and vane 18 urges vane 18 clockwise against stop 43. Rotation of member 35 about pin 36 by pressure on lever 37 allows vane 11 to rotate clockwise  under the action of spring 26 until one of a plurality of teeth 17 engages the tip of a needle 16, the position of which is controlled by a galvanometer 15 connected to a scene luminance level detecting device. Continued rotation of member 35 causes spring 42 to pass over pin 23 whence the spring 42 drives vane 18 so that its aperture passes over the aperture in vane 11 to effect an exposure. Upon release of lever 37, a light blocking tab 38 moves in front of the exposure aperture, spring 42 passes over pin 23 and vane 18 is driven to its starting position. The effective f/number of the exposure aperture is determined by which of the plurality of teeth is engaged by the needle 16, and blade 18 moves at the same speed for all exposures to thus give the shortest exposure time when the aperture is at minimum value and the longest exposure time when the aperture is at maximum value.
