B—11
(5) Shutter Charging:
1. When film is advanced, 8836 and 8839 are rotated, which in turn
makes the embossed portion of 8840 of 8839 push A pin 2 connected
to (8547). Thus (8547) is rotated.
2. When (8547) is rotated, it turns 8506 by means of 8519 connected
thereto.
3. At each end of (8506) is glued a string, to which is attached (8538)
of the first curtain. When (8506) is rotated, the strings are wound
up towards (8506) against the spring force effected on (8524) and
(8527), and thus the first curtain moves in the arrowed direction.
