This has happened before...I have a Canon AE-1 and the thing that winds the film back up, the spiny thing (sorry I forget what it's called...) fell off, so there's that piece, and then a little metal rectangular piece, and a screw with a rectangular top. If I put the screw in, I can pull it up and open the part where the film goes. But I've got film in there, and I've used the roll, so I need to wind the film again so I don't expose the film. I had this fixed at a Shutterbug store before, but I don't know how they did it, I can't figure out how to put the pieces together, I don't know if anyone else can help but I need to fix it ASAP because I'm on a trip right now, and it would be great to have my camera. So any ideas would help.
Thanks!
