7.3.2 LIGHT SOURCE AND EXPOSURE
This model uses an LED for the light source. Light from the LED array board (LEDB) [A] goes to
the original via the light guiding panel [B] and the reflector [C]. Then from the original, the light
follows the light path to the CCD [J].
The LED lamps are disposed at both ends so that sufficient light reaches the left and right ends
of the document.
The light reflected from the original travels as follows:
LED exposure -> 1
st
mirror [D] -> 2
nd
mirror [E] -> 3
rd
mirror [F] -> 4
th
mirror [G] -> 5
