    • A method of color reversal treatment of an exposed silver halide photographic material is disclosed. The method involves treating the exposed material with 2 both type black-and-white developing solutions. The first solution contains a compound represented by the general formula (I):R.sub.2 --S--R.sub.1).sub.d --S--R.sub.2 (I)wherein R.sub.1 represents an alkylene group having 2 to 10 carbon atoms, which may have ether bonds, R.sub.2 represents an alkyl group having 2 to 10 carbon atoms which alkyl group may have substituents, ether bonds or ester bonds, and d represents an integer of 0 to 3. The second black-and-white developing solution is a conventional solution. By utilizing the two solutions and specifically the first solution containing the compound of general formula (I) it is possible to obtain good photographic images having a high maximum density and good color balance. Further, images having different sensitivities can be obtained with the identical photographic materials when the conditions are varied.
    • 公开了曝光的卤化银照相材料的颜色反转处理方法。 该方法包括用2种两种类型的黑白显影溶液处理暴露的材料。 第一溶液含有通式(I)表示的化合物:R2-S-R1)dS-R2(Ⅰ)其中R1表示可具有醚键的碳原子数2〜10的亚烷基,R2表示烷基 具有2〜10个碳原子的烷基可以具有取代基,醚键或酯键,d表示0〜3的整数。第二黑白显影液为常规溶液。 通过利用两种溶液,特别是通过含有通式(I)的化合物的第一溶液,可以获得具有高的最大密度和良好的颜色平衡的良好的照相图像。 此外,当条件变化时,可以用相同的照相材料获得具有不同灵敏度的图像。

    • A sheet transport apparatus is provided with a processing section having a processing position to process a sheet, and a first roller pair and a second roller pair disposed at the front and back of the processing section to transport the sheet to the processing section at a predetermined velocity. Each of driving transmission mechanisms respectively for driving the first roller pair and second roller pair is provided with a rotary shaft for supporting the roller, a rotary member provided with a circular fit hole to fit with the rotary shaft, and a holder member in which a D-shaped press-fit hole is formed to press-fit to the rotary shaft, and to the rotary shaft are attached the rotary member with the circular fit hole formed therein and the holder member with the D-shaped press-fit hole formed therein. Then, in attaching the holder member and rotary member to the rotary shaft, a concave portion of the holder member is fitted with a convex portion of the rotary member so that the rotary member and the holder member are substantially integrally coupled.By this means, since driving transferred to the rotary member from a driving motor is transferred to the rotary shaft from the rotary member through the holder member, without deforming the rotary member by stress of the rotary member in attaching to the rotary shaft, it is possible to transfer driving of the rotary member to the rotary shaft with reliability, and the transport rollers are capable of transporting the sheet at a stable velocity without fluctuations in rotation.
    • 片材输送装置设有具有处理片材的处理位置的处理部分,以及设置在处理部分的前后的第一辊对和第二辊对,以便以预定的方式将片材输送到处理部分 速度。 分别用于驱动第一辊对和第二辊对的驱动传递机构分别设置有用于支撑辊的旋转轴,设置有与旋转轴配合的圆形配合孔的旋转构件,以及保持构件, D形压配合孔形成为压配合到旋转轴,并且旋转轴安装有形成在其中的圆形配合孔的旋转构件,并且保持构件在其中形成有D形压配合孔 。 然后,在将保持器构件和旋转构件安装到旋转轴上时,保持构件的凹部装配有旋转构件的凸部,使得旋转构件和保持构件基本上一体地联接。 通过这种方式,由于从驱动电动机转移到旋转构件的驱动通过保持构件从旋转构件传递到旋转轴,并且在旋转构件附接到旋转轴的应力下不会使旋转构件变形, 可以可靠地将旋转构件的驱动传递到旋转轴,并且输送辊能够以稳定的速度传送片材而没有旋转波动。

    • Provided is a document reading apparatus in which an original document fed by feeding means to contact glass having a predetermined reading position is read by reading means. Then, the document reading apparatus is provided with a guide unit having a guide member for guiding the original document to be fed to the contact glass, and a backup unit to back up the original document to be read, and the guide unit is configured to be able to travel between a close position to near the contact glass and an open position to distance from the contact glass. In the guide unit is formed a concave portion for removably accommodating the backup unit, and the backup unit is configured so that an original document guide face of the guide member and an original document guide face in the backup unit form a continuous guide face when the guide unit travels to the close position.Then, the guide unit is moved to the open position to perform cleaning of the backup unit and contact glass. Further, the backup unit is removed to perform maintenance.
    • 提供了一种文件读取装置,其中通过读取装置读取通过馈送装置馈送的原稿以接触具有预定读取位置的玻璃。 然后,文件读取装置设置有引导单元,该引导单元具有用于引导要馈送到接触玻璃的原稿的引导构件和用于备份待读取的原稿的备用单元,并且引导单元被配置为 能够在靠近接触玻璃的关闭位置和离开接触玻璃的打开位置之间行进。 在引导单元中形成有用于可拆卸地容纳备用单元的凹部,并且备用单元构造成使得当引导构件的原稿引导面和备用单元中的原稿引导面形成连续的引导面时 导向单元行进到关闭位置。 然后,引导单元移动到打开位置以执行备用单元和接触玻璃的清洁。 此外,删除备份单元以执行维护。
