Dual-Frame Exposure Operation
In the dual-frame exposure mode, lever (1) is held in a neutral position by the spring
“A.” This allows the Light Interception Blade to be set in the position shown in Figure 7.
Now, as the Motor runs, pin (a) rotates clockwise as the arrows indicate. However, pin
(a) does not turn the Mode Change Lever because it is not engaged in the Lever slot.
Consequently, both apertures remain open and only Shutter charging occurs.
