How do they work?

Well, yesterday i was cleaning the basement of one of my friend's house when i found this:


A very good looking box with a lot of interesting stuff in! Motors, mechanics, gears, belts...and whatever people can drem up! Perfect for some cool robotic projects! So i brought everything in my house and i started testing it. I have no idea of where all this stuff came from, it seems a sort of photocophy machine, or something like that. All the guesses are welcomed!
