Abstract
Abstract An electronic photographic and processing camera having an optical system for inverting an image for exposure on photosensitive paper. The exposed paper is advanced after exposure by rollers into an attached processing unit that includes processing fluid and a cutter for cutting off individual exposures. The processing unit is detachable from the camera and includes additional rollers to seal the fluid therein.

An electronic photographic camera comprising a photographic optical system adaPted to invert either the vertical or horizontal direction of an image formed through a photographic lens; photosensitive paper cutting means adapted to cut off a photosensitive paper, which has been exposed in an exposure window disposed backwardly of said photographic optical system, from the unexposed photosensitive paper that is attached to and follows said exposed photosensitive paper; processing means detachably mounted on the camera body and having a photosensitive paper inlet and outlet aperture which is sealed against the leadage of the processing solution from said processing means; means adapted to advance the exposed photosensitive paper into said inlet and outlet aperture; means adapted to detachably mount said processing means on said camera body; a spiral shaped processing chamber located within said processing means; a pair of abutting rollers located within and at the entrance to said processing chamber, said rollers adapted to guide said photosensitive paper into said spiral chamber and to provide sealing against leakage of the processing solution; said processing chamber having an opening for the passage of developing solution therethrough, said opening being closable by a removable pug during operation of the developing.

An electronic photographic camera comprising a photographic optical system adapted to invert either the vertical or horizontal direction of an image formed through a photographic lens; photosensitive paper cutting means adapted to cut off a photosensitive paper which has been exposed in an exposure window disposed backwardly of said photographic optical system, from the unexposed photosensitive paper that is attached to and follows said exposed photosensitive paper; processing means detachably mounted on the camera body and having a photosensitive paper inlet and outlet aperture which is sealed against the leadage of the processing solution from said processing means; means adapted to advance the exposed photosensitive paper into said inlet and outlet aperture; means adapted to detachably mount said processing means on said camera body; the construction of said processing means being such that a pair of photographic feed rollers which are pressed against each other and adapted to pull out the photosensitive paper extending from the camera body into said processing means whenever the photosensitive paper has been exposed, are drivingly coupled to a locking member for locking said processing means in position relative to said camera body; and said pair of feed rollers are adapted to be spaced apart from each other when said processing means is unlocked from said camera body.
