Abstract
1381465 Shutter mechanism SEIKO KOKI K K 28 March 1973 [28 March 1972] 14913/73 Heading G2A A focal plane shutter comprises a group of shutter-opening blades and a group of shutterclosing blades, each group comprising a slitforming blade and a plurality of non-slit-forming blades and having a primary operating lever for all the blades and an auxiliary operating lever for the slit-forming blade, the primary and auxiliary operating levers forming a parallelogram linkage with the slit-forming blade, each non-slit-forming blade having a pin-and-slot connection with the primary operating lever and one of the non-slitforming blades being pivotally connected to the slit-forming blade. Blade groups 5 and 9 of similarly constructed and operated shutteropening and -closing blades are situated between frame members forming a window 2. Blade group 5 (shown in the closed position) comprises a slitforming blade 5a having pivots 5g and 5h forming a parallelogram linkage with a primary operating lever 3 pivoted at 3a and an auxiliary operating lever 4 pivoted at 4a. Lever 3 has a pin-and slot connection with a first non-slit-forming blade 5b which is pivotally connected to the slit-forming blade at 5h (as shown) or at another point (13), Fig.5 (not shown) and with further non-slitforming blades 5c-e having a common fixed pivot 6. Pivot 6 may be dispensed with, blades 5c-e being pivotally connected in series to blade 5b.
