ABSTRACT:
A spread roller assembly including a housing and a pair of juxtaposed rollers for spreading a processing liquid across a layer of an exposed film unit so as to initiate the formation of a visible image therein. The ends of one of the rollers are mounted in a pair of movable bearings for enabling the roller to move toward and away from the other roller. Each of the movable bearings includes a film engaging member which moves into engagement with a trailing end of a film unit, as the latter moves out of engagement with the rollers, so as to releasably retain the film unit in engagement with a wall of the housing. A unique spring arrangement is provided which applies substantially all of its forces in a direction perpendicular to the axes of the rollers thereby substantially eliminating any adverse side forces being applied to the assembly. The support members for the rollers are adapted to be snap fitted to the housing.
