摘要:
A machine capable of producing photographic colour prints, both from images captured on film and from digitally encoded images, consists essentially in a conventional machine as used to make colour prints from images on film, also comprising a one-line cathode ray tube (7 or 7a or 7b) positioned along the path followed by a strip of light-sensitive paper (31) from a supply roll (3) to a set of chemical treatment baths (60), preceding or following the printing surface (29), of which the projecting head (71) generates a pencil-thin line comprising a high number of pixels in a notably broad range of colours. The single lines are emitted gradually and in ordered succession by the projecting head (71), impacting on a corresponding length of the light-sensitive paper (31) as it advances across the head and thus generating an image of high definition and chromatic fidelity directly on the light-sensitive surface.
摘要:
Device for processing photographic material comprising a plurality of treating baths (1-9) containing developing , bleaching , fixing and stabilizing solutions. During the working operations, the treating baths are successively crossed by the photographic material to be treated. The refilling of the treating baths is obtained by means of pumps (41-47) and pipes (31-37) which draw the treating solutions from each restoring container (11-13) as well as the treating water from a water-reservoir (24). A driving device (50) of the refilling pumps cooperates with the level sensors (S1-S6) of the restoring containers in order to stop the refilling process and to actuate an auxiliary pump (71-73) as soon as one of the restoring containers is empty. The auxiliary pump (71-73) removes the residual treating solutions from the restoring containers through an additional pipe (61-63) connected with each restoring container (11-13). The device according to the invention facilitates the maintenance operations and makes simple and economical the disposal of the restoring containers
摘要:
A system of measuring the densities of images on photographic films, comprising a conventional projection unit, in which a measuring device (7) is mounted slidably between the film (6) and the lens (9), capable of longitudinal movement in relation to the film and equipped with a plurality of light-transducing elements (74) arrayed in mutual alignment transversely to the image (I) and positioned to receive respective quantities of light from discrete portions (ZP) of a transverse reading zone (Z), which are admitted through a slot (72), reflected by a mirror (71) and focused by a lens (75). With the measuring device (7) translating longitudinally, such that the slot (72) can cover the image (I) progressively and in its entirety, the single values sensed by the light-transducing elements (74) are fed into an electronic processor (C) and processed together with other data in such a way as to determine the filtration and illumination parameters governing reproduction of the image (I).
摘要:
A combination machine (3) for developing and printing photographic material continously and automatically, composed of modules (4, 5, 6, 7) allowing easy mutual assembly and separation. The basic structure of such a machine comprises a module (4) for printing from film onto paper, surmounting a print developing module (5), this in turn positioned alongside a module (6) housing devices by which prints emerging from the developing module (5) are dried, as well as containers holding the liquids used to regenerate and replenish the various chemical treatment baths. An additional module (7) for developing film can be positioned on top of the drier module (6), whilst the print module (4) is also hinged at the bottom along one side to the outer edge of the module (5) beneath in such a way as to tilt clear and allow easy access to the inside of the machine (3) for the purposes of cleaning and servicing.
