| Title: |
Fixed Image Projecting Apparatus |
| Abstract: |
A fixed image projection system that can project an image for a short or
long period of time without damage to the film. The system is comprised of
a light source having a halogen lamp and a cold coated reflector
detachably mounted on a housing having film guides or rails for receiving
a film frame. The housing includes a plurality of whisper fans that draw
cool air into the housing and expel it from the opposite sides of the
housing to maintain a relatively cool temperature at the film frame.
Preferably, the fans have a dual speed control to allow a higher speed as
an option. A lens barrel is detachably supported on the opposite side of
the housing from the light source and includes movable lenses to focus the
image. Images may be fed into the system on a film frame one at a time, or
by motorized film canisters that allow forward or backward advancement to
a selected image on a roll containing multiple images.
