3.1 OVERVIEW
[H]
[G]
[J]
[K]
This film projector unit allows making copies from the following kinds of films:
35 mm positive slides (both mount films and glass mount films)
35 mm negative or positive strip films
Positive or negative films of wide size
(60 x 45 / 60 x 60 / 60 x 70 / 60 x 80 / 60 x 90 mm / 4" x 5" /
maximum size of 140 x 210 mm or 5.5" x 8.2")

[D]
[F]
The light from the projector lamp [A] is reflected by the reflector [B] and
reaches the film (35 mm) in the film/slide holder [C] through the non-spherical
lens [D], heat filter [E], and condenser lenses [F]. The projected film image
reaches the mirror [G] through the correction filter (positive or negative) [H]
and projection lens [I]. Then the mirror reflects the image to the exposure
glass through the Fresnel lens [J]. The first scanner moves under the
exposure glass to read the projected film image and the light of the image is
converted to R/G/B electrical signals by the CCD [K].
The projected image on the exposure glass is enlarged about 6 times the 35
mm film’s image.
In the case of wide size films, the first scanner reads the film placed on the
exposure glass directly using the light from the projector lamp.
The lamp cooling fan turns on and off according to the temperature of the
projector lamp section detected by the lamp thermistor. It turns on at around
45°C and turns off at around 44°C.

3.2 SHADING
[35 mm Slide Positive] or
[Positive Film Under Lens] On
[35 mm Strip Negative] or
[Negative Film Under Lens] On
[A][A]
When the projector unit is selected, shading should be done after selecting
the type of films. The shading should be done with a base film and the
N-correction filter for the negative films and with the P-correction filter for the
positive films.
The N-correction filter corrects color of the projected light. The P-correction
filter corrects the light intensity of the projected light so that it becomes similar
to that for the negative films.
When "Shading" [A] on the touch panel display is pressed, the first scanner
moves and stops under the mirror unit. Then AGC (Auto Gain Control) for the
light intensity from the projector lamp is performed. Shading for black and
white levels is also performed after the AGC.
This "Shading" should be performed whenever the type of film is changed or
the mirror unit is moved.

The film image projected through the projection lens [A] is reflected to the
Fresnel lens [B] by the mirror [C].
The Fresnel lens consists of two components, a circle pitch Fresnel lens [D]
and a parallel pitch Fresnel lens [E]. The circle pitch Fresnel lens changes
the spreading light to the parallel light. The parallel Fresnel lens collects the
light from the circle pitch Fresnel lens in the main scan direction so that all
the light reaches the color CCD lens [F].
The use of these two types of Fresnel lens makes the most of the light
intensity from the projector lamp.
