During the forward stroke of the Pick Carrier, the Counter Wheel (Figure 2-14) is indexed by a spring arm
on the Pick Carrier. The Counter detent acts as a ratchet.
After one full revolution, the Timing Gear cam allows the Outer Door Stop Link to rotate CCW, opening
the DKEC switch which signals the microprocessor to shut off the motor.

Exposing the Picture
Note: Described below are the electromechanical actions of the
main drive train which take place during exposure how the
viewfinder blind and the taking mirror are moved.
For an overall list of the steps in the exposure and processing sequence of operations, see the Sequence of
Operations chart at the beginning of the Theory of Operation.
When the shutter release (S1A-S1B) button is depressed, Solenoid 1 is energized and begins closing the
shutter blades.
The main drive train now has the following tasks: to block the Viewfinder with the Viewfinder Blind
before the Taking Mirror begins to move, to prevent the film from being light- struck; and second, to
release and drive the Taking Mirror into position for exposing the film. Here is how these actions are
accomplished.
