The carriage serves to store and feed out lengths of film into a camera exposure station. A source of vacuum acting between a sheet of flexible plastic material and a translucent platen for the camera at the exposure station causes the film to be flattened against the platen for film exposure. Thereafter, the vacuum is broken by movement of the carriage and the exposed film is urged into the nip of rollers which carry the film through a developing station supported by the table. ## Claims ### Claim 1 Apparatus for use in combination with a camera having an object plane and an image plane comprising: a. an elongated table coupled to the camera having a top surface parallel to the image plane of the camera; b. a film transport section slidably carried on the table at one end thereof; c. a light tight cassette on the transport section; d. a supply of imaging film in said cassette; e. means carried by the transport section to advance at least a portion of the imaging film from the cassette on to the table; f. A translucent platen carried by the table to receive light directed through the camera from the object plane; g. an elongated flexible sheet of light filtering material yieldably secured at one end within the transport section and adapted to be extended from said transport section along the table to overlie the platen; h. control means to advance the imaging film across the table and beneath the light filtering material to overlie the platen; i. at least one groove in the top surface of the table adjacent the platen and beneath the elongated flexible sheet; j. a vacuum source coupled to said groove; k. means to control the vacuum source to evacuate air from the space between the flexible sheet and the platen to bring the film into uniform contact upon the platen; l. a processing station carried by the table opposite the transport section; m. means to interrupt the vacuum source to release the atmospheric pressure against the flexible sheet and the film; and, n. film advancing means carried by the transport section to urge the film into the processing station as the transport section is advanced along the table in the direction of said processing station. ### Claim 2 (depends on 1) Apparatus according to claim 1 in which the table is carried by a bed secured to the camera, said bed having upstanding parallel side members and elongated tracks on said side members to support the film transport station. ### Claim 3 (depends on 1) Apparatus according to claim 1 in which the film transport section includes a carriage, a cassette housing on said carriage and a spring loaded roller at the front of the carriage to receive one end of the flexible sheet. ### Claim 4 (depends on 3) Apparatus according to claim 3 in which the film transport section is provided with a transverse shear disposed in the path of the imaging film fed from the cassette whereby the said film may be cut into desired lengths. ### Claim 5 (depends on 3) Apparatus according to claim 3 in which the imaging film is directed into a pair of feed rollers journaled within the cassette, said rollers being operatively coupled to the control means to advance the imaging film across the table. ### Claim 6 (depends on 1) Apparatus according to claim 1 in which the top surface of the platen is the image plane of the camera. ### Claim 7 (depends on 3) Apparatus according to claim 3 in which the spring loaded roller is under tension to yieldably take up the flexible sheet. ### Claim 8 (depends on 1) Apparatus according to claim 1 in which the elongated flexible sheet is formed of a material which excludes substantially all light which would expose the photosensitive film. ### Claim 9 (depends on 1) Apparatus according to claim 1 in which the elongated flexible sheet is provided with a window through which the leading edge of the imaging film may be viewed for positioning. ### Claim 10 (depends on 1) Apparatus according to claim 1 in which the elongated flexible sheet is formed with a pattern to provide passages therebetween for the passage of air between the said sheet and the film. ### Claim 11 (depends on 10) Apparatus according to claim 10 in which the elongated flexible sheet is provided with a continuous flat strip-like portion around the edges thereof. ### Claim 12 (depends on 10) Apparatus according to claim 10 in which the pattern consists of a plurality of protuberances on the surface facing the table. ### Claim 13 (depends on 1) Apparatus according to claim 1 in which the flexible sheet is provided with securing means at the free end thereof to hold it in an extended position overlying the film at all times after the film leaves the cassette end until it is within the processing station. ### Claim 14 (depends on 4) Apparatus according to claim 4 in which the film advancing means comprises an elongated member carried across the path of the film and engagable with the trailing edge of the film after it has been sheared from the supply. ### Claim 15 (depends on 14) Apparatus according to claim 14 in which the elongated member is movably secured to the transport section so as to shift upwardly as the transport section is moved in a direction away from the processing station. ### Claim 16 (depends on 15) Apparatus according to claim 15 in which the elongated member is a brush-like member having a plurality of bristles canted in the direction of the film feed. ### Claim 17 (depends on 3) Apparatus according to claim 3 in which the film transport section includes a second spring loaded roller at the rear of the carriage and a flexible sheet of opaque material secured at one end to said second roller and at its other end to the table whereby said opaque sheet will unroll from the second roller as the carriage is moved toward the processing station to overlie the table and be taken up by the second roller as the carriage is returned to the end of the table opposite the processing station. ### Claim 18 (depends on 11) Apparatus according to claim 11 in which the means to control the vacuum source comprises the elongated flexible sheet, a port in the top surface of the table in communication with ambient air and the flat strip in the said elongated strip, whereby proper positioning of the transport station along the table will cause the flexible sheet to cover or open said port. ### Claim 19 (depends on 1) Apparatus according to claim 1 in which the processing station includes a first set of processing rollers in line contact with each other, said rollers hving a nip therebetween to receive the exposed film, a switch means in the path of the exposed film as it enters the switch and a brake member carried by the film transporting section and operatively connected to the said switch to stop the movement of the said transporting section when the exposed film reaches the nip of the first processing rollers. ### Claim 20 (depends on 19) Apparatus according to claim 19 in which the brake is an electro-magnetic brake.
