Scanner Drive Cable (Rear)
10-5. Scanner and Mirrors Carriages Moving Mechanism
<Scanner>
•
The Scanner projects an even amount of light from Exposure Lamp LA1,
as it moves, onto the entire surface of the original and reflects this light,
with the 1st Mirror, onto the 2nd and 3rd Mirrors.
•
It is driven by Scanner Motor M11 with the Scanner Drive Cables
attached to the front and rear at a speed appropriate to the set zoom
ratio. The speed is varied from the reference speed of 340.0 mm/sec.
which is the scan speed for the full size mode.
•
The Scanner is at its home position when Scanner Reference Position
Sensor PC1 is blocked. The position serves as the reference for the
scan motion.
<2nd/3rd Mirrors Carriage>
•
The 2nd and 3rd Mirrors are mounted to their holder at right angles to
each other. They function to let the light reflected off the 1st Mirror strike
the 4th and 5th Mirrors through the Lens.
•
The 2nd/3rd Mirrors Carriage is also moved by the Scanner Drive
Cables and pulleys driven by M11. It travels at a speed half that of the
Scanner, thereby keeping constant the optical path length between the
Original Glass and PC Drum.
•
The 2nd/3rd Mirrors Carriage has been adjusted to run parallel with the
Scanner though Focus-Positioning of the Scanner and Mirrors Carriage.
