A photographic print processing apparatus, comprises (a) a first exposing section to expose an image of a photographic film onto an unexposed photographic paper; (b) a development processing section to develop the exposed photographic paper; (c) a first conveying passage to convey the exposed photographic paper from the first exposing section to the development processing section; (d) a second conveying passage branched from the first conveying passage and joined with the first conveying passage; (e) a second exposing section, provided on the second conveying passage, to expose an image onto a photographic paper; and (f) a control section to control the first passage and the second passage so as to convey the photographic paper.

Photographic print processing apparatus

An apparatus for processing a photographic paper, includes a distributor between an exposure station and a developing station so that plural sheets of photographic papers exposed at the exposure station can be conveyed in parallel in the developing station.

Photographic processing system

The invention provides an apparatus for printing an image of a negative film on a photographic print paper. The apparatus is equipped with a zoom lens for changing a printing magnification rate and the zoom lens incorporates an adjustable diaphragm for changing an aperture size. A standard F-number for each of possible magnification rates is predetermined in view of actual printing result, and a resultant F-number is stored in a memory for each of possible magnification rates. In the apparatus provided a sensor, disposed on the optical axis of the zoom lens, for detecting the illuminance of a projected surface on the photographic print paper and CPU for controlling the adjustable diaphragm in response to the detected illuminance to determine an optimum aperture size to obtain the predetermined F-number for each of possible magnification rates. The optimum aperture size is stored in the memory for each of possible magnification rates.
