    • A silver halide photographic light-sensitive material is described, comprising a support having provided thereon at least one light-sensitive silver halide emulsion layer associated with a substantially immobile, positive one-equivalent redox compound capable of releasing a photographically useful compound or a precursor thereof as a result of a redox reaction, said compound being represented by formula (I) ##STR1## wherein Acp represents an anion center precursor capable of causing --Z--Q to be released by a quinonemethide type releasing reaction when being reduced R.sup.1 and R.sup.2 each represents a hydrogen atom, a substituted or unsubstituted aryl group; Z represents a divalent atomic group; Q represents a group capable of becoming a photographically useful compound or a precursor thereof when released, provided that Q does not contain an atom or atomic group which functions as an electrophilic center that induces an intramolecular substitution reaction; Ball represents a ballast group; M represents a substituent; A represents an organic group which connects Acp, ##STR2## M, and Ball; and n and m each represents an integer of 1 or more.
    • 描述了一种卤化银照相感光材料,其包括在其上提供至少一种感光卤化银乳剂层的载体,所述至少一种感光卤化银乳剂层与能够释放照相有用化合物或其前体的基本上不可移动的正一当量氧化还原化合物相关联 作为氧化还原反应的结果,所述化合物由式(I)表示,其中Acp表示当还原R1和R2时能够通过醌类化合物释放反应使-ZQ释放的阴离子中心前体 各自表示氢原子,取代或未取代的芳基; Z表示二价原子团; Q表示当释放时能够成为照相用化合物或其前体的基团,条件是Q不含作为诱导分子内取代反应的亲电子中心的原子或原子团; 球代表一个镇压组; M表示取代基; A表示连接Acp, M和Ball的有机基团; n和m各自表示1以上的整数。

    • A paper guiding device in a copying apparatus includes, in opposition, a lower guide plate having a main flat portion and an upper guide plate having a main flat portion. A plurality of rising pieces, having top edges and being laterally spaced apart upon the upper side of the main flat portion of the lower guide plate, rise above the lower guide plate and extend in the direction of movement of the copying paper. A plurality of hanging pieces, having lower edges and are laterally spaced apart on the lower side of the main flat portion of the lower guide plate, hang from the upper guide plate and extend in the direction of movement of the copying paper. The top edges and the lower edges define a path of movement of the copying paper while having minimal contact with the paper. A plurality of openings through the upper guide plate and an opening through each of the hanging pieces dissipate heat from the copying paper to substantially prevent the accumulation of moisture on the copying paper and in the improved paper guiding device.
    • 复印装置中的纸引导装置相对地包括具有主平面部分和具有主平坦部分的上引导板的下引导板。 在下导板的主平面部分的上侧具有顶边并且横向隔开的多个升件在上导板上升起并沿着复印纸的移动方向延伸。 在下导板的主平面部分的下侧上具有下边缘并且横向隔开的多个悬挂件从上引导板悬挂并沿着复印纸的移动方向延伸。 顶部边缘和下边缘限定复印纸的移动路径,同时与纸张的接触最小。 通过上引导板的多个开口和通过每个悬挂件的开口从复印纸散发热量,以基本上防止水分在复印纸上和改进的纸引导装置中的积聚。
