3 .4 .2 Intermittent Sprocket Drive
Via pulses the main drive encoder counts quantity of film (transport unit = 1 picture),
which is transported out of feed sprocket into film gate.
If one “transport unit” is completely counted and shutter position is dark the motor of
intermittent sprocket carries on film for one picture.
This operation is controlled by a microprocessor which is mounted on the main board.
