I've had these since 2002 without doing the research. What can you tell me about these devices?

This gizmo looks similar to the Polaroid camera I once used to 'capture' the screen of an oscilloscope.
However, I seem to remember that the frame going from the camera proper to the rectangular mask for the screen was covered in a shroud to exclude ambient light.

I would then digitize the output by counting the screens grid lines on the resulting photo.

That was 45 plus years ago... ugh! 🥲 Thus, I could be completely mistaken.
 
An oscilloscope camera is one possibility; another being a simple document copying device you set on a printed document.
 
It's a polaroid copy camera. Looks like it's set to photograph whatever you put in the rectangle underneath. The stand holds it the proper distance from whatever you're photographing. Like @Kino said, it's likely just for documents - possibly even a particular kind of document. It doesn't have a ring flash like the polaroid evidence camera. It appears fairly simple. It's not particularly useful right now since there's no film available for it.
 
You could convert it to take 4x5 film holders but... why?

I am sure it was useful in it's day and age for it's intended purpose, but now not so much.
 
Just a heads up - us moderators are floating the idea about combining all your "what do I have here?" threads into one single thread.
Otherwise you may find it nearly impossible to find information later.
 
Someone might be able to make some use of the lens on that Polaroid copy camera - if they are into building their own photographic bits and bobs.
 
I have one fitted to an old Kodak folder utilizing 120(top Pic) and 70mm(bottom pic). I'm quite pleased with it

Of all the devices that I inherited, this one gets the most attention. I hesitate to ship it but, so far, it has not sold locally.

I understand your not wanting me to clutter up the site with too many postings. My intention was to get my total number of postings up to 20 so I could advertise this stuff for sale and communicate with members here by conversation.
