    • A method of processing an exposed black-and-white silver halide photographic film material, the method having the steps of developing in a developer solution, fixing in a fixer solution, replenishing of fixer and developer solution, rinsing in a washing solution and drying, characterized in that fixing is performed in one step and under such conditions that a "silver equilibrium ratio" of less than 2.0 is maintained, the said ratio being defined as the ratio between actual by the film material in the rinsing step through carry-over (cross-over) of silver from the fixing solution to the washing solution and amount of silver brought into the washing solution and the total amount of silver that theoretically could be brought into the washing solution by the film material by such carry-over; a "fixer to film silver ratio" of less than 0.2 is obtained, this ratio being defined as the ratio between silver content in "running equilibrium condition of the fixer" and amount of silver in the film material to be fixed in the fixing step, wherein said "running equilibrium condition of the fixer" is the condition attained after having replenished said fixing solution twice. By this method an ecologically favourable minimization of silver content in the washing solution has been obtained without impairing the processing speed, without enhancing processing costs and without excessive regeneration.
    • 一种处理曝光的黑白卤化银照相胶片材料的方法,该方法具有在显影剂溶液中显影,固定在定影剂溶液中,补充定影剂和显影剂溶液,在洗涤溶液中漂洗和干燥的步骤, 其特征在于,在一个步骤中进行定影,并且在保持小于2.0的“银平衡比”的条件下,所述比例被定义为在冲洗步骤中由薄膜材料实际通过托盘之间的比例( 交联)从固定溶液到洗涤溶液的银和进入洗涤溶液的银量和理论上可以通过这种携带被膜材料带入洗涤溶液中的银的总量; 获得小于0.2的“定影剂银膜比”小于0.2,该比率定义为定影步骤中要固定的薄膜材料中的银含量与“定影剂的运行平衡条件”中的银量之比, 其中所述“定影剂的运行平衡条件”是在补充所述定影液两次之后获得的条件。 通过这种方法,在不损害加工速度的前提下,可以获得洗涤溶液中银含量的生态有利的最小化,而不会增加加工成本并且不会过度再生。

    • An automatic processing apparatus having a processing solution tank for processing a silver halide photosensitive material, includes a container accommodating a set of solid processing agents which can process a predetermined amount of the material, a detector for detecting an amount of the material to be processed, and a supplier for supplying an amount of the solid processing agents accommodated in the container into the processing solution tank in accordance with a detected amount of the material. The apparatus further includes a controller for controlling the supplier in which the controller controls the supplier to supply all amount of the solid processing agents remained in the container to the processing solution tank, when the processing agents are remained in the container after the predetermined amount of the material is completed to be processed. The controller controls the supplier to inhibit a supply of another set of the solid processing agents until the predetermined amount of the material is completed to be processed, when all amount of the solid processing agents in the container has been supplied onto the processing solution tank before the predetermined amount of the material is completed to be processed.
    • 一种具有用于处理卤化银感光材料的处理溶液槽的自动处理装置,包括容纳一组可处理预定量的固体处理剂的容器,用于检测待处理材料量的检测器, 以及供应商,用于根据检测到的材料量将容纳在容器中的固体处理剂的量供应到处理溶液罐中。 该设备还包括控制器,用于控制供应商,其中控制器控制供应商将残留在容器中的所有固体处理剂提供给处理溶液罐,当处理剂在预定量的 材料完成处理。 当所有量的固体处理剂已经被提供到处理溶液罐前,控制器控制供应商抑制另一组固体处理剂的供应,直到完成预定量的材料被处理 完成预定量的材料以进行处理。
