4.3.2 Reader Path
The Reader Path is established when the Power Switch is turned ON and
remains formed except during a scan movement.
The image on the microfilm is projected onto the entire area of the Screen
by means of the two Reader Path Mirrors.
The light path between the Projection Lamp and Screen measures
1,293mm.
4.3.3 Scan Path
When in the Scan mode, the 1st Scan Path Mirror moves to a position that
will block the Reader Path.
It then turns to direct the film image through the four Scan Path Mirrors
onto the CCD so that it can read the image data in the sub-scanning
direction.
The light path between the Projection Lamp and CCD measures
1,298mm.
