摘要： A sheet feeding apparatus includes a retard mechanism to prevent the inadvertent feeding of doubled or overlapped sheets. The retard mechanism includes a plurality of belts in an assembly positioned adjacent to a sheet feeding roller, and rotating in such a direction as to retard the sheets being fed. The retard assembly is mounted on the free end of a lever arm pivotally secured adjacent to its other end to the base of the sheet feeding apparatus. The lever arm with the retard assembly mounted thereon is spring-urged toward the feed roller, but may be moved slightly away from said roller to accommodate the thickness of the sheet being fed between the feed roller and the retard assembly. A dual spring arrangement contained in the lever arm permits the lever arm to move with relatively little force to accommodate passage of a single sheet, but to resist more vigorously any additional movement, such as would be required for the passage of double or overlapped sheets. A one-way retaining device permits movement of the lever arm and retard assembly toward the feed rollers as the roller and belts wear, but prevents movement away from said roller except for the limited movement permitted to accommodate sheets during feeding. The retaining device may be released to permit the lever arm and retard assembly to be swung away from the feed roller for replacement of the feed roller and retard belts when worn.
摘要翻译： 片材进给装置包括防止双重或重叠片材的无意中进给的延迟机构。 延迟机构包括位于片材进给辊附近的组件中的多个带子，并沿着延迟供给的片材的方向旋转。 延迟组件安装在杠杆臂的自由端上，杠杆臂相对于其另一端可枢转地固定到片材进给装置的基部。 安装有延迟组件的杠杆臂被弹簧推向进给辊，但是可以稍微远离所述辊移动以适应在进给辊和延迟组件之间供给的片材的厚度。 包含在杠杆臂中的双弹簧布置允许杠杆臂以相对较小的力移动以适应单个片材的通过，但是更有力地抵抗任何额外的运动，例如通过双重或重叠片材所需的任何附加运动。 当辊和皮带磨损时，单向保持装置允许杠杆臂和延迟组件朝向进给辊移动，但是除了允许在进给期间容纳片材的有限运动之外，防止移动远离所述辊。 可以释放保持装置以允许杠杆臂和延迟组件摆脱进给辊，以便在穿着时更换进给辊和延迟带。

摘要： A mounting member or connecting device is used to connect a first member to a second member. The connecting device includes a male member and a female member which are coupled together through an opening in the first member. The first member may be a divider panel and the second member may be a cover panel, for example, with the second member having first and second parallel fingers thereon. A tolerance ring, formed in the shape of a band which is less than a complete circle. is mounted on a cylindrical section of the male and female members. The tolerance ring has corrugations thereon which are crushed to some degree when the first and second fingers are pushed on to the associated cylindrical section with the tolerance ring thereon. This connection provides a vibration free connection and also eliminates ESD problems between the connected members.

摘要： A document is cupped at a first time to stiffen and straighten the document before the document is stacked in the interior chamber of a document stacker. The cupped document is cupped at a second time which is different from the first time to maintain the document stiff and straight as the document is being stacked in the interior chamber of the document stacker so as to reduce the chance of a stacking defect from occurring when a succeeding document is subsequently stacked on top of the document. A trailing edge of the document is engaged to urge the trailing edge of the document in a direction away from direction of movement of the document into the interior chamber of the document stacker so as to prevent a succeeding document which is to be subsequently stack on top of the document from stacking out of sequence relative to the document. The document is frictionally engaged as the document is being stacked in the interior chamber of the document stacker to prevent the document from moving too far into the interior chamber so as to allow the trailing edge of the document to be engaged and urged in the direction away from direction of movement of the document into the interior chamber of the document stacker.
摘要翻译： 在文件堆放在文件堆垛机的内部室中之前，文件首次被硬化并加强并拉直文件。 杯状文件第二次与第一次拔罐，以便当文件堆叠在文件堆垛机的内部腔室中时保持文件的硬度和直线度，以便减少堆垛缺陷发生的可能性 随后将文档堆叠在文档的顶部。 文件的后缘被接合以沿着远离文件移动到文件堆垛机的内部空间的方向的方向推动文件的后缘，以便防止随后的堆叠在后面的文档 的文档从堆栈顺序相对于文档。 文件被摩擦地接合，因为文件正在堆叠在文件堆垛机的内部室中，以防止文件移动到太远的内部室，以便允许文件的后缘被接合并被推向远离的方向 从文件的移动方向到文件堆垛机的内部室。

摘要： A check processing module includes a hardware device disposed along a document track. The hardware device processes document items moving from an upstream end of the document track to a downstream end of the document track. A number of outer panels covers the hardware device during operation of the check processing module. At least one idler roller engages a document item in the document track when the idler roller is in a non-retracted position. An actuatable mechanism is provided for, when actuated, moving the idler roller from the non-retracted position to a retracted position away from a document item in the document track to allow an operator to more easily gain access to the document track while the outer panels remain covering the hardware device positioned along the document track.

摘要： A self-aligning inking roll for a printer which includes an inking roll, an ink transfer roll, a printer, and an endless ribbon mounted on the transfer roll and the printer so as to provide a fresh supply of ink thereto. The inking roll is mounted on an aligner member which is mounted on a support member, with the support member being mounted on an arm which is resiliently biased towards the transfer roll. The aligner member is mounted on the support member at the midpoint of the aligner member so as to provide a fulcrum area which enables the aligner member with the inking roll thereon to pivot and thereby establish a line contact with the transfer roll with the ribbon thereon.
