(Figure 2-9)
1. In this mode, disk (A), the M and MS blades and other components behave in a similar
fashion to the single frame mode, except for the following:
2. As shown in the lower half of Figure 2-9, the step cams at the ends of the mode select
lever move pins (d) and (d’) out of the way of the MS blade (b), permitting it to rotate
freely with disc (A). Thus the MS blade (b) stops at the position shown, resulting in
exposure windows “A” and “C” being blocked, and “B” and “D” open for a dual-frame
exposure.
