This film projector unit allows making copie s from the followin g kind s 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
(45 x 60 / 60 x 60 / 60 x 70 / 60 x 80 / 60 x 90 mm / 4" x 5" /
maximum size of 142 x 210 mm or 5.6" x 8.2")
The light from the projector lamp [A] is reflect ed by the refle cto r [B] and
reaches the film (35 mm) in the film/slide holder [C] through the non-spherical
lens [D], heat filter [E], and cond enser len ses [F]. The projected film image
reaches the mirror [G] through the correctio n filt er (po sitive or negat ive) [H]
and projection lens [I]. Then the mirror re fle cts th e image on to the expo sure
glass through the Fresnel lens [J]. The first scanner moves under th e
exposure glass to read the project ed film image and the light of the image is
converted to R/G/B elect rical sign als by th e CCD [K] .
The 35 mm film’s image is enlarged about 6 times when projected onto the
exposure glass.
In the case of wide films, the first scanner reads the film placed on the
exposure glass directly using the lig ht from th e pro ject or lamp .
The lamp cooling fan turns on and off depending on the temperature of the
projector lamp section dete cte d by the lamp thermistor. It turns on at around
45°C and turns off at around 44°C.

3.2 SHADING
When the projector un it is select ed , shading should be done aft er sele ctin g
the type of film. The shading should be done with a base film and the
N-correction filter for the negative films and with the P-correction filter
(without base film) for the positive films.
The N-correction filter corrects the color and inten sity of the proje cte d ligh t.
The P-correction filter corrects the ligh t int ensity of the proje cte d light so th at
it becomes similar to that for the negative films.
When "Shading" is performed , th e first scann er move s and stops und er th e
mirror unit. Then AGC (Auto Gain Control) for the light intensity from the
projector lamp is performed. Sh ad ing for bla ck and white levels is also
performed after th e AG C.
This "Shading" should be performe d whe never th e typ e of film is chang ed or
the mirror unit is moved.

The film image projected through the projectio n len s [A] is reflect ed 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 divergent light to paralle l light. The parallel Fresnel lens collect s the light
from the circle pitch Fresnel lens in the main scan directio n 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 ligh t
intensity from the projector lamp.
