Abstract
A microfilm reader-printer has a reservoir for copy sheets located near the top of a housing and when a permanent copy of an image projected on a screen (via a lens and a mirror) is required, a sheet is manually removed from the reservoir and fed to the input of a charging station. The sheet is mechanically fed through the charging station to drop by gravity into an exposure station for exposure with the image. Following exposure, the sheet makes a second gravity-induced drop into the nip of a roller pair forming the inlet of a development station. The sheet is fed through the development station, and then the printed sheet exits from an opening below a viewing window.
