Detailed Operations
Pressing the Shutter Button pivots the Release Lever and Pressure Lever, rotating the
Light Interception Blade (Figure 2-3).
Although the Light Interception Blade ears no longer block the Baseplate openings, no
exposure occurs because the Shutter Blade remains latched. (Figure 3-12 in Section 3
shows the left and Right Hooks engaging the Shutter Blade driving Wheel, resulting in
this latching action.)

Pressing the Shutter Button further causes the Pressure Lever to unlatch a Wheel
coupled to the Shutter Blade (Figure 2-4 as well as Figure 3-20 & 21 in Section 3).
The Wheel, under the tension of a compressed spring, now rotates rapidly and spins
the Shutter Blade past the baseplate openings, exposing the film.
When the Shutter Button is released, a spring pulls the Levers and Blades back to their
original positions, and relatches the Shutter Blade.
