IMAGE READ MECHANISM
[1] Outline
A halogen lamp is used as the light source, and the light from
the lamp is directed onto the original.
The light reflected off the original is reflected by the 1st, 2nd and
3rd mirrors shown in Fig.1, then passed through the lens and
directed onto the CCD image sensor.
The CCD image sensor consists of 5000 pixels. One pixel is
7 µm in length, and the length on the original that can be read
by one pixel is 63.5 µm.
