ABSTRACT OF THE DISCLOSURE This invention relates to a camera back for selective releasable attachment to a front camera body comprising two generally flat housings in end to end pivotal connection with respect to each other wherein the first of the housings is adapted to slidably accept a plurality of stacked film units of the self-developing type therein in a manner whereby the photosensitive surface of the forwardmost film unit is positioned at an exposure window corresponding with the focal plane of the front camera body when the camera back is releas- ably attached to the front camera body. The second housing defines an imbibing chamber for receipt therein of exposed film units in a light tight environment. One open end of the imbibing chamber includes a pair of processing rollers there- across in operative association with other film advancing mechanisms which sequentially advance exposed film units from their position at the exposure window of the first housing into the imbibing chamber of the second housing. Automatic drive means are provided by a motor conveniently spaced in a portion of the first housing spaced laterally apart from the processing rollers in noninterfering relationship with the path of advancement of the exposed film units through the processing rollers into the imbibing chamber. In addition, there may be provided an adapter in releasable, light tight connection with respect to the camera back and extending above at least a part of the motor housing portion to accommodate releasable, light tight connection to the front camera body, such that the exposure window of the camera back aligns in substantial coincidence with respect to the focal plane of the front camera body.
