An opaque projector, also known as an epidiascope, is a device for projecting an image that is on a non-transparent medium. One can buy an opaque projector from Amazon.

This is referred to as an opaque overhead projector, or sometimes simply as an "opaque projector."

This is in contrast to the regular overhead projector which must have transparencies to project, an opaque projector can project an image of opaque objects such as the paper pages of a book.

The projector is broken again.

I operate the projector at the cinema.
