Pivotally mounted spread roller assembly

Claim 1

Apparatus for spreading a processing liquid across a layer of an exposed film unit to initiate the formation of a visible image therein comprising: a pair of rollers; means for supporting said pair of rollers in juxtaposition to define a gap through which an exposed film unit is adapted to be advanced while said rollers spread a processing liquid across a layer of the exposed film unit to initiate the formation of a visible image in the film unit; means for pivotally coupling said supporting means to a camera housing for movement between an operative position, wherein said gap is located to receive the exposed film unit as it approaches said gap, and an inoperative position wherein said pair of rollers are available for maintenance purposes; manually operable means mounted for movement between a first position, in which it prevents ambient light from striking the exposed film unit as the film unit initially emerges from between said pair of rollers, and a second position in which said pair of rollers are exposed to the ambient light; a gear mounted on one end of at least one of said pair of rollers, said gear being in driven engagement with a camera power train when said manually operable means is in said first position and out of engagement therewith when said manually operable means is in said second position and said pair of rollers may be manually and freely rotated for inspection of their surfaces; and means extending from said manually operable means into engagement with said supporting means for moving said supporting means from said operative position to said inoperative position as said manually operable means is moved from said first position to said second position.
