Title: Exposure factor setting device for photographic apparatus
Inventor: AMBROSIUS DIETER
IPC: G03B7/00
Filed: 1969-01-02
Abstract: 1,245,701. Exposure control. KOMBINAT PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Jan. 2, 1969, No.320/69. Heading G2A. Two rotatable exposure factor setting devices (e. g. a film speed setting ring 6 and an exposure time setting ring 3) can be coupled together, or uncoupled. Ring 6 rotates in a recess 4 in ring 3 and recess 4 is extended radially over half its circumference to form a crescent-shaped additional recess 5. Ring 3 has a fixed pin 8, which cooperates with one of a number of notches 9 on the underside of ring 6. A spring 7 fixed to ring 3 urges ring 6 to the left, and when pin 8 is aligned with a notch 9, ring 6 is able to be so moved. This brings ring 6 out of recess 5, and the engagement of pin 8 and notch 9 couples rings 6 and 3 together. If ring 6 is pushed manually to the right, against the spring, it enters recess 5. Notch 9 moves clear of pin 8, and then the rings are disengaged, so that ring 6 can now be rotated independently of ring 3 to any other desired setting. Ring 6 has two inwardly extending guide lugs 12, into which fit arms 13 of a slide plate 14. Pins 15 on plate 14 fit slidingly into slots 16 in a further plate 17, which is connected by a shaft 18 to the moving element of a metering device, which can thus rotate ring 6 when in the uncoupled position.
