초록 ▼

The chemical activity of the developer in a film processor is stabilized by a replenishment system which includes a controlled fluid supply arrangement operative to effect an initial replenishment based upon certain predetermined factors including the length or area of a sheet to be processed as detected at the processor input, an assumed minimum exposure present on each image-bearing sheet to be processed, and the customary degradation of developer activity resulting from oxidation effects as determined empirically. The initial replenishment is later supplemented, if necessary, by effecting additional replenishment following the processing of film sheets, based upon a determination of the actual image density and image area present in those sheets. Variations in developer activity, due to introduction of the initial and supplemental replenishment fluid increments, are minimized by providing a mixing tank in parallel with at least a portion of the main developing tank in the processor, to increase the effective volume of developer solution in the overall system.

대표청구항 ▼

In a film processor of the type comprising developing, fixing, and washing tanks, means for transporting exposed film along a predetermined path from the input of said processor through said tanks in succession to the output of said processor, a supply of replenishment fluid, and control means operative to selectively feed fluid from said supply to replenish the developer in said developing tank thereby to compensate for the lowered activity of said developer resulting from the processing of said film, the improvement comprising a pre-development sensor disposed adjacent said transport path upstream of said developing tank and responsive to at least the presence of a sheet of film at the processor input for activating said control means to feed an initial increment of replenishment fluid from said supply to said developing tank prior to the processing of said sheet, and a post-development sensor disposed adjacent said transport path downstream of said fixing tank and responsive to at least the image density in at least one processed sheet of film for selectively activating said control means to feed a further increment of replenishment fluid from said supply to said developing tank subsequent to the film processing operation.
