摘要:
An image reading device for photographic printing comprising an optical lens mechanism, a monochrome CCD image device arranged at a focal position on an optical axis of the optical lens mechanism, a filter rotation plate having a plurality of color filters rotatably arranged on the optical axis, and a cut filter for blocking unnecessary light arranged on the optical axis, wherein a light quantity correction means for obtaining stepwise spectral characteristics is arranged on the optical axis. The reflected light due to the conventional ND coating and the influences of the boundary plane and the parallel degree between the cut filter and the color filter are disappeared, whereby the occurrence of flare, ghost and color divergence can be prevented.

Das fotografisches Kopiergerät weist eine erste Belichtungseinrichtung zum Aufbelichten von fotografischen Negativ- oder Positivvorlagen (N) und eine zweite Belichtungseinrichtung (2) zum Aufbelichten von Bildschirmvorlagen (46) auf fotografisches Kopiermaterial (P) auf. Die zweite Belichtungseinrichtung (2) umfasst eine etwa im rechten Winkel zum Belichtungsstrahlengang (E) der ersten Belichtungseinrichtung angeordnete Kathodenstrahlröhre (20) samt Ansteuersystem, eine Anordnung von Farbfiltern (22), ein Objektiv (24) und einen Umlenkspiegel (23), mit Hilfe dessen die von der Kathodenstrahlröhre (20) emittierte Bildinformation auf das fotografische Kopiermaterial (P) lenkbar ist. Die Farbfilteranordnung (22), das Objektiv (24) und der Umlenkspiegel (23) sind erfindungsgemäss als bauliche Einheit zu einer Abbildungsoptik (21) zusammengefasst, die wahlweise an Stelle eines der ersten Belichtungseinrichtung zugehörigen Abbildungbildungsobjektivs in den Belichtungsstrahlengang (E) einbringbar ist.
摘要:
An apparatus for arraying sheets of photosensitive material provided in a film printing (X)/developing (Y) apparatus. Along the path to a lower outlet are mounted one-way rollers (36) and high-speed rollers (37), so that the sheets of photosensitive material (PC) in a two-line zigzag arrangement will be fed at high speed. The sheets of photosensitive material thus fed out of the lower outlet are overlapped one upon another on the pan by means of a conveyor (39) in the order of the frames in one roll of film. Optionally a sorting guide (33) is provided for selectively feeding the sheets of photosensitive material (PC) according to their size. The sorted sheets are fed further either in a one-line arrangement or in a two-line zigzag arrangement to an upper outlet or to the lower outlet by guides.

In a photosensitive material processing apparatus (1), a photosensitive material taking on the form of a long strip (A) is fed into a conveyance mechanism and conveyed in this form along a predetermined conveyance path. An exposure device, a reservoir section, a development processing section (4), and a cutter (6) are located in the conveyance path. The exposure device (31) carries out scanning exposing operations on the long strip of the photosensitive material and thereby forms latent images on the long strip of the photosensitive material (A). In the reservoir section, a looped portion for serving as a buffer for conveyance is formed in the long strip of the photosensitive material, on which the latent images have been formed. In the development processing section (4), development processing is carried out on the long strip of the photosensitive material (A), which is fed via the reservoir section. The cutter cuts (6) the long strip of the photosensitive material, which has been subjected to the development processing, into sheets having a predetermined length.
摘要:
A printer processor (11a,11e), a film processor (11b,11f), and a densitometer (11c) are connected to a personal computer (13) via a port controller (12). For diagnosing the operation condition of a photographic equipment, a check sample is formed by the photographic equipment. The check sample is set to the densitometer to fetch the measured density data into the personal computer (13). If the operation condition of the photographic equipment is abnormal, the personal computer fetches the operation data under management in the photographic equipment to determine a countermeasure against the abnormal state. The countermeasure is transferred to the photographic equipment to automatically adjust the adjust failure element. In order to remotely control a plurality of lab shops, each lab shop is provided with a sub-computer connected to the photographic equipment. The headquarters are provided with a main computer (191) storing therein a management program. The main computer (191) fetches the data of the sub-computer via a communication line. In accordance with the fetched data, the headquarters (190) remotely control the quality, production state, and stock state of consumable goods at each lab shop (180,182). The port controller (12) finds an idle time of a CPU at each lab shop, and fetches the data from the photographic equipment during the idle time.
摘要:
An image printer (1) includes a developing unit (D) for developing an exposed photosensitive material (3), a plurality of transport members (20-23,40-43) for transporting the photosensitive material to the developing unit through exposing positions (E1-E3) provided respectively in a plurality of photosensitive-material transport passages arranged in parallel to each other, and a plurality of projection exposure units (P1,P2) for exposing a film image on to the photosensitive material. The projection units are provided respectively for the exposing positions of the transport members.
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.
