8. Exposure Interlocking System
When an aperture figure of Diaphragm Ring is set, Diaphragm Contact (4105) will get in
touch with Diaphragm Resistor (4118) via Diaphragm Pulley (0211). Then a resistance figure
_ corresponding to the set aperture figure will be set, and it plus the resistance figure on the
ASA side will be transmitted to the circuit side as the exposure factor.
Note: Diaphragm SW will be turned on only for the open light measurement.
