<Opening and Closing Operations of the Buffer Shutter>
By pushing the Developing Assembly in the main body, edge of the Supply Mouth on the
assembly hits to leading edge of the Buffer Shutter.
By pushing the assembly in farther, the Buffer Shutter moves to the rear so the Supply Mouth
is opened.
The Shutter Arm goes down by spring pressure, and it interlocks with the protrusion on the
Developing Shutter.
By pulling the Developing Assembly out, the Shutter Arm is pushed by the protrusion on the
Developing Shutter, so the Buffer Shutter is closed followed by the Supply Mouth. The Shutter
Arm lifts up by hitting to the bottom of the Hopper.
