Shutter Release
(Figure 2-3)
1. As the shutter is released, the magnet set lever is pulled away, hook (j) is unlatched
from main lever (f), and charge spring “C” actuates the shutter.
2. In a 1/60th-sec. exposure, shutter speed is reduced by pin “B” on the main lever (f)
striking the shock-absorbing cam “A” midway in its rotation.
3. In a 1/125th-sec. exposure, the shock-absorbing cam “A” is moved out of the path of
pin “B” by the speed selector lever, allowing spring “C” to drive the shutter blade with
maximum speed.
4. Just before shutter release is completed, the main lever (f) closes the shutter switch
(S4 in Figure. 2-5) to start the motor.
