What is this device called?

Polaroid was an American company best known for its instant film and cameras. The company was founded in 1937 by Edwin H. Land (1909-1991), to exploit the use of its Polaroid polarizing polymer. Land ran the company until 1981.

The Polaroid Land camera was produced between 1947 and 1983 and is a self-developing type camera. Polaroid Land Camera Model 95 was the first to be commercially available. It produced prints in about 1 minute. It was first available to the public in 1948.

Land’s new approach was to get the dyes in the film to move from the negative to the positive by way of a reagent by employing diffusion transfer to. A negative sheet inside the camera itself was exposed, then it was lined up with a positive sheet and squeezed through rollers which spread a reagent in between the two layers, creating what could be called a developing film sandwich of sorts. The negative developed quickly and after a minute, the back of the camera could be opened so the negative could be peeled away. What was left was the actual print.
