This is a passport or identity card camera from GBC (General Binding
Corporation). It takes photos on Polaroid Pack 100 film in passport
size (4 different photos on one picture) in passport size. GBC sold the
material for making identity cards for companies and congresses. Mine
does not work, so I opened it to search for the problem. So there are
photos from the inside as well. The camera is very sturdy, it weighs
more than 5kg.
So here are some photos:
Left side (right side looks similar).
Lens and (maybe) sensor.
Aperture setting by turning the lens barrel.
The upper and the bottom part come off easily, just 4 screws to pull each time. It's a modular system, easy to repair.
