- Photographic apparatus of the self-developing type are well known-in the art and generally include film advancing means for engaging and moving an exposed film unit out of its exposureposition and into engage ment with a pair of pressure-applying members, e.g.,
- the processingvcompositioncontained within the'pod would notonly spread from the front of the film .unit to the rear but it,the composition, would also have a tendency to move laterally toward one side of the'film unit because of the angle "between-the pressure-applyingmeans and the discharge end(s) of the pod(s). Movement of the processing composition toward .the' one side. of the film unit and away from the other side thereof during front to rear spreading mayresult in a spread which does not cover the rear corner of the other side of the film unit.
- the film unit includes, a pod o'rcontainer, of
- processing composition e.g.,- liquid, havinga sealed
- the film-advancing means is constructed and positioned such that the film unit is not canted 'a's it moves into engagement with the bite of thejrollers, i.e.,-the,leading end of the filmunit is generally parallel with the axes of the rollers therebyenablingthe rollers to maximize the spread of the processing composition across thephotosensitive layer of the film unit.
- the film unit were camera with pressure-applying means, e.g., a pair of rollers, which are adapted to spread the processing composition ac'ross the film unit ina layer having an asymmetrical thickness as measured transversely of the film .unit with the minimum depth of the layer being located on that side of the film 'unit where'incomplete coverage of the photosensitive area by the composition is most likely to-occur.”
- pressure-applying means e.g., a pair of rollers
- One of the rollers preferably the bottom roller, has
- the other roller i.e., the top roller, includes collars at each end thereof which are adapted to engage the ends of the bottom roller for-providing a gap'of predeterminedminimum depth therebetween to facilitate entry of the-fiIm unit.
- the top roller also includes an intermediate film unit engaging portion having a length slightly less than the lateral'distance betweenthe binding elements and film unit engaging endlportions'located between each end of the intermediate portion and the collars. The aforementioned end portions of the top roller areadapted to cooperate with the opposite end portions of the bottomroller to engage the I binding elements ofthe film' unit as it passes therebetween to define the'depth of the layer of vprocessing composition to be spread across the photosensitive layer.
- one-of the end portions of the top roller is provided with a smaller diameter than the other end portion of the top roller, thus resulting in the longitudinally extending asymmetrically configured gap between thekrollers when a film. unit is passing therebetween.
- the end portion of the top roller having the reduced diameter is located on the side of the roller assembly which first receives a portion of the leadingend of the canted or skewed filmunit because, it is usually the rear comer of the film unit located on the same side of thelongitudinal axis of the film unit as 1 that portion which .first enters the bite of the rollers where the aforementioned incomplete coverage of the photosensitive layer will occur.
- the asymmetrically configured gap between the rollers which is a result of reducing the diameter of one of the end portions of the top roller, provides a structure wherein the depth of the layer of processing composition is thinner on that side of the film unit which first enters the bite of the rollers than on the other side of the film unit, i.e., the rollers spread the processing composition across the photosensitive layer of the film unit in a layer having an asymmetrical thickness, as measured in a direction transverse to the direction of movement of the film unit relative to the rollers.
- the pressure-applying means preferably include a pair of rollers which define a gap through which an exposed film unit is adapted to be moved, and a torsion spring the'opposite ends of which are adapted to engage opposite ends of one of,
- the asymmetrical loading produces an elongated asymmetrically configured gap between the rollers with the depth of the gap toward the end having the greaterforce being less than that at the other end, to produce a layer of processing compositionhaving an asymmetrical thickness.
- the end of the roller having the greatest biasing force is adapted to spread the processing composition in a-thinner layer across that side of the film unit where the aforementioned incomplete spread is most likely to occur, thereby insuring complete coverage of the photosensitive area of the film unit.
- Another object of the invention is to provide pressure-applying means including a first member having a longitudinally extending, asymmetrically configured surface defining-one portion of a gap and a second member having a longitudinally extending, symmetrically configured portion defining a second portion of a gap.
- Another object of the invention is to asymmetrically bias at least one of a pair of pressure-applying members to provide a spread of processing composition of nonuniformthickness.
- Still another object of the invention is to provide pho asymmetrically spreading a processing composition across the film unit in a layer of non-uniform thickness.
- Still another object of the invention is to provide a spreading assembly for spreading a processing composition across substantially the entire photosensitive area of an exposed film'unit whichwas originally moved into engagement with the spreading assembly in a skewed or possessing the construction, combination of elements
- the pressure-applying means preferably include a pair of juxtaposed rollers which cooperate with each other to define a gap having an asymmetrical configuration.
- One of the rollers, preferably the upper roller, has asubstantial'ly uniform diameter throughout a major portion thereof while the other roller has a substantially candlepin" configuration, i.e., its diameter gradually decreases from a maximum diameter intermediate its ends to a minimum diameter at or near its opposite ends.
- the configuration of the other roller is also asymmetrical in that its major diameter is closer to one end of the roller than the other end, and more specifically, is located closer to the end of the roller assembly which first receives a leading end portion of an exposed film unit.
- offsetting the maxi- Another object of the invention is to provide a camera of the self-developing type with pressure-applying means having a longitudinally extending, asymmetriand arrangement of parts which are exemplified in the following detailed disclosure, and the. scope of the application of which will be indicated in the claims.

- Reflecting assembly68 includes a support70 having a planar mirror 72 mounted on one side thereof and an echelon type reflecting surface 74 on the other side. As is morefully described in U.S. Pat. No. 3,678,831, reflecting assembly 68 is adapted to be pivoted'between an exposure position adjacent a mirror 76 located on housing section 18 wherein light from lens 24 is reflected-by mirror 72 to expose the uppermost film unit closely adjacent cassette 32 wherein echelon'surface rotatably mountedon ashaft 108 by a pair of ball bearing assemblies 110. Opposite ends of theshaft 108 extend through elongated slots 112 and 114 provided in the ears 82 and 84 of the bracket 80.
- Flattened ends 116 and 118 of the torsion spring 96 seat in appropriately positioned annular recesses 120 of the shaft 108 so that the force of that spring continually urges the roller 60 towards itsupwardmost position within the slots 112 and 114 as viewed-in FIG. 2.
- the support member 94 is configured with a pair of cutouts 121 to accommodateinitial loading of the spring 96 and subsequent displacement of its flattened ends -1 l6 and l 18 responsive to translatory movement of the shaft 108 along the brackets slots 112 and 114.

- the assembly comprises a spread roll bracket 80 preferably formed from a unitary piece 'of sheet metal such as a stainless or carbon steelj Bracket 80 includes a pair of upturned ears 82 and 84 joined together by a central portion 86 comprising a support 88 and spaced apart substantially parallel flange portions 90 and 92.
- a rigid structural support member-94 is configured to seat against the support 88 intermediate the ears 82 and 84 and nested between the flange portions 90 and 92 of the bracket80.
- a pair of rivets 95 serve to secure the support member 94 to the bracket'80.
- a specially configured'torsion spring 96 rests in tracks 98 the force of the torsion spring 96.
- the roller 62 is provided with a'pairof spaced apart annular recesses 132 strategically positioned as shownto receive selected portions of specially configured longitudin a1 edge bindings 134 of the film unit 42 in order to preclude the red-framing effect'in accordance with the teachings of US. Pat. No. 3,647,441 by Albert J. Bachelder entitled PHOTOGRAPHIC APPARATUS AND METHOD, issued'on Mar. 7, 1972.
- button 28 is depressed to initiate an exposure cycle. Subsequent to actuation of button 28, exposure chamber 12 is made lighttight by closing shutter 24 and the viewfinders entrance pupil l1 1. Motor 52 is energized to move reflecting assembly 68 to the up or exposure position. Motor 52 is then stopped and the shutter opened and closed to expose the forwardmost film unit 42 in cassette 32. Motor 52 is again' started to drive gear train 54 to move member 8 I I right side thereby resulting in the composition on the left side being depleted before the corner area 153 of the film unit has been covered by the processing com- 66 to the left, as viewed in FIG.
- the present invention substantially obviates this problem by constructing thespreading assembly such that it spreads the processing composition in a thinner layer on the left side of the film's longitudinal axis 115 than on the right thereby increasing the area that can be covered by the processing composition on the left side. Specifically, this is accomplished by providing the left end portion 127 of roller 62 with a diameter less than that of intermediate section 130 (asbest seen in FIG. 2a) and right end portion 129, the latter two having substantially the same diameters. As shown in FIG. 7
- initial rupturing of the pod 46 by rollers 60 and 62 presents an advancing wave front as shown at 140.
- the major portion of the wave front progressively flattens out while the created as a result of the acute angle between a line containing the discharge end 49 of pod 46, which is perpendicular to the longitudinal axis 115, and a plane containing the longitudinal axes of the rollers.
- Lateral movement of the'processing composition to the right may result in the left.
- the thickness-of the layer of processing composition may be between .002 and .003 inches. Thinning out the thickness of the layer of processing composition on the left side of the film unit by approximately .0001 inch relative to the right side of the film unit is generally sufficient to obtain complete coverage of area 153.
- roller 62' is similar to roller 62 except that the left side of shaft 108 (as viewed in FIG. 2) with a spring load of 4.75 lbs. and the right side of the'shaft with aload of 3.75 lbs. provides a spread which com-,
- roller 60 when a film unit enters the bite of rollers 60 and 62, roller 60 ismoved away from roller 62'. As the film unit enters between the rollers, the gap therebetween changes to an asymmetrical configuration with the minimum depth of the gap being on the left side of the roller assembly. Accordingly, when the rollers rupture pod 46, the processing composition 47 which was contained in the pod closest to the left side'of the film unit is spread in a thinner layer across the photosensitive area, therebyenabling the composition to be spread over a greater area, i.e., the entire area defined by opening 48.
- thespreading assembly includes a top roller 62' and the bottom roller 60' mounted for' rotation about parallel axes 131 and-13s.
- Roller 60 is adapted tocooperate with roller 62 to' define a longitudinally extending (from end-to-end of therollers) asymmetrically configured gap therebetween when a film unit is located between the rollerspspecifically, roller 60 is provided with a candlepin configuration having a major diameterat 160 which gradually decreases to similar minor diameters near its ends 162 and 164. It should be noted that the major diameter 160 is located offcenter, 'i.e., it is closer to end 162 than end 164,
- rollers 60 and 62'- cooperate with each other to spread the processing compositionv across a photosensitive layer of the film unit in a layer having an asymmetrical thickness, as measured in a directiontransverse to the direction of movement of the filmrelative to the rollers, with the minimum thickness of the layer being located on that side of bite of the rollers.
