2. The blank exposure shutter is moved by the cam attached to the bottom of the lens when the
lens moves to the blank exposure position, which corresponds to the cassette size.
The blank solenoid (SL4) goes OFF as soon as the blank exposure shutter has moved to a cut-
out to fix the shutter in position; cut-offs are provided for each cassette size. Direct and En-
large copies are made with the mechanism in this position.
3. When the reduce mode is selected, the lens first returns to the home position and then moves to
a position that corresponds to the selected reduction ratio. At the time, the blank exposure
shutter is moved over a distance corresponding to the selected reduction ratio by the cam at-
tached to the bottom of the lens to execute blank exposure.
