Abstract: 986,898. Combined taking, developing and printing apparatus. GENERAL ANILINE & FILM CORPORATION. Jan. 25,1962 [Feb. 3, 1961], No. 2852/62. Headings G2A and G2J. A print-producing camera includes a support 21,a camera assembly 15 mounted on the support, and a processing assembly 17 within a housing detachably secured to the camera assembly to provide a single integral unit, the housing containing a strip film supply 46, a processing solution applicator 62 to develop the film after exposure by the camera assembly, a strip photographic printing paper supply 70, a printing lamp arrangement 65 for photographically printing from the developed negative film on to the positive printing paper, a positive print processing applicator 74, metered drive means 64, 76 for moving both the film and the printing paper strips through the processing assembly, and selectively operable means 156, 91 for cutting off both the film and the paper. As shown the assembly 17 is a lighttight camera back attachment provided with a dark slide shutter 50 and comprises separable and hingedly connected negative developing and positive printing units 10,11, the unit 10 comprising the elements 62, 65, 64,156 and the unit 11 comprising the elements 70, 74, 76, 91. The unit 11 is demountably and hingedly supported by pins 90 engaged by separable arms 92, 93 on the unit 10 and is held closed on to the latter by spring latches 95 thereon engaging latch pins 96. The two metering drive rollers 64, 76 are operated by separate electric motors, the drive to roller 76 incorporating a friction band slipping clutch (Figs. 5,13,14 not shown). Each processing applicator, e.g. applicator 74, comprises a tray divided into a number of parallel channels extending across the width of the strip being processed, each channel being fed with solution at one end by supply line 135 (Fig. 15) and emptied via outlet line 137 connected to a submersed extractor pump 202, atmospheric pressure causing solution to rise up the supply line to the applicator. The supply and outlet lines may be cabled together as at 136 (Fig. 3) and the processing solution containers 196 may be disposed under a housing 33 on the mobile base 26 carrying the vertical supports 18 for the camera assembly. To facilitate threading the applicators 62, 74 and the drive back-up rollers 66, 78 are movable away from the strip paths. Focusing of the camera is effected by racking movement of the line board 13, vertical tilt is controlled by hand wheel 32 and worm-driven sector gear 40 causing rotation about cross-bar 22, and the vertical position of the camera assembly is fixed by clamping knobs 25 on T-connections slidable on the vertical posts from the tops 49 of which the camera assembly is supported on counter-balancing springs 24. The lens board 13 can be tilted about both vertical and horizontal axes by release of knobs 19,57 and can be raised or lowered by knobs 59 (Fig. 2 not shown). The printing lamp arrangement 65 may comprise a number of lamps arranged side-by-side above a slit extending across the width of the film and instead of cutting off the processed film it may be wound up on a reel 81 mounted on the outside of the processing assembly. The printing paper 70 is contained in a light tight cassette 72.
