Abstract
Abstract The disclosure is directed to an extremely compact camera-processor which is configured to sharply reverse the direction of the exposed light sensitive sheet as it leaves the exposure plane. The light sensitive sheet is thereafter driven downwardly into a processor bath along with a relatively flimsy receptor sheet.
