Exposure Counting Mechanism
(Figure 2-4)
1. As the motor runs and turns gear (a), an eccentric crank pin on the gear causes
lever (b) to move back and forth.
2. As lever (b) moves laterally back toward the motor, its hook end engages a tooth of
gear (c) and indexes it one notch. The exposure counter dial correspondingly rotates
one count.
3. To prevent lever (b) during its opposite travel from rotating gear (c) backwards,
pawl (d) pulls in and locks the gear against backward rotation.
