Abstract
1441729 Diaphragm-setting slide AGFAGEVAERT AG 28 June 1974 [28 June 1973] 28794/74 Heading G2A A camera has a manually-operated slide 2 with two ranges of diaphragm-setting positions (indicated on a scale 3), one range being for daylight operation and the other being for self-regulating flash operation (using a known flash circuit 12), slide 2 closing a switch 10 during the latter operation. Slide 2 is connected to a toothed rack 4 which operates a diaphragm-adjusting member 7 via gears 5 and 6 and which also closes switch 10 by means of a projection 9. The flash apparatus may be contained with the camera housing as shown or may be an attachment Fig. 3, (not shown)
