摘要： A method for registering a stack of sheets with respect to perpendicularly related axes includes the steps of providing a first sleeve for accommodating the stack of sheets; providing a stop at one end of the sleeve; placing the stack in the sleeve; and providing in the sleeve a fluid stream, whereby the fluid stream moves the sheets down the sleeve in unison and moves the sheets into registration with a wall of the sleeve and the stop. In a modified method a second sleeve is provided in alignment with and adjacent to said first sleeve. The sheets are first placed inside the second sleeve and fluid is drawn from the first sleeve to move the stack. Assistance in moving the stack is provided by fluid injected into the second sleeve, care being taken to prevent a net flow of air out of a gap between the first and second sleeves.
摘要翻译： 一种相对于垂直相关轴线记录纸张堆叠的方法包括以下步骤：提供用于容纳纸叠的第一套筒; 在套筒的一端提供止动件; 将堆叠放置在套筒中; 并且在套筒中提供流体流，由此流体流一致地将片材向下移动到套筒上并将片材移动到与套筒壁和止挡件对准的位置。 在改进的方法中，第二套筒设置成与所述第一套筒对准并相邻。 首先将片材放置在第二套筒的内部，并且从第一套筒抽出流体以移动堆叠。 通过注入到第二套筒中的流体提供移动堆叠的帮助，注意防止空气净流出第一和第二套筒之间的间隙。

摘要： A stacker includes a rectangular housing within which there is located a vertically movable platform. A vertical wall of the housing includes, along an upper region, an orifice through which sheets may be fed into the housing, and each of the other three vertical walls includes a series of fluid outlet ports, at the same level as the orifice, each series of ports being coupled to a vacuum source. The top of the housing includes an array of fluid inlet ports which are coupled to a fluid source. The fluid source cooperates with outlet ports and vacuum sources to create a fluid stream in the housing which biases a sheet entering through the orifice, selectively, against one of two corners in the housing. Sheets in the housing are also biased towards the platform by movable spring members extending into the housing through the orifice. The spring members are moved out of the way of a sheet entering the housing through the orifice by a detector which controls a solenoid yoked to the spring members. Tension in the springs is detected to position the platform in the housing so that the top-most sheet supported by the platform is located at a predetermined level.

摘要： A system wherein documents are presented to an exposure station of reproduction apparatus includes a housing in which a rack for storing documents is located. The rack includes a plurality of pockets in each of which a document may be stored, the rack being movable in a vertical direction so that any one of its pockets may be aligned with an opening in the housing. Fluid streams are used to either move a document in an aligned pocket through the opening and to the exposure station or from the exposure station into the pocket. Copies of documents presented to the exposure station are made by the reproduction apparatus. Adjacent the housing there is located an inverter into which documents from the rack are fluidically fed as desired. Inverted documents are returned to the rack with the assistance of a fluid stream. Inverted documents may be fed to the exposure station to provide duplex copies.

摘要： In a first embodiment, a stop having a plurality of ports is connected to and covers an end of a rectangular sleeve. In a region near the stop, a narrow wall of the sleeve also has a plurality of ports. A nozzle coupled to a pump provides a flow of air into the other end of the sleeve and the air exits through the ports. With this arrangement, a rectangular sheet inserted into said other end of the sleeve is fluidly brought into registration with the narrow wall and stop. After the sheet has been registered, fluid inserted or drawn through holes in a wide wall of the sleeve maintains the sheet in contact with one of the wide walls, thereby further registering the sheet. In a second embodiment, similar to the first, the narrow wall and stop include internal projections against which an inserted sheet is registered. In a third embodiment, similar to the first, a manifold is coupled to the ports and a vacuum pump is coupled to the manifold to accelerate registration. In a fourth embodiment, similar to the third, the pumps are replaced with a reversible pump to register and discharge a sheet.

摘要： A system for presenting documents to a slit-scan exposure station includes a first fluidic storage station in which a rack for storing documents is located. The rack includes a plurality of pockets in each of which a document may be stored, the rack being movable in a vertical direction. Fluid is used to move a document in a pocket partially out of the storage apparatus through an opening and into registration with a gate and a wall of the pocket. Thereafter, the gate is opened and a drive associated with the exposure station moves the partially ejected document past a scan window. The rack is then vertically stepped to align another pocket with the opening and the procedure is repeated. Exposed documents are moved to a second fluidic storage station, similar to the first. At this station fluid drawn through an opening moves a document into a pocket of a rack and vertical movement of the rack is used to provide a separate pocket for each of the documents. Reversal of the fluid streams in the storage stations and the drive may be used in cooperation with a gate at the opening of the second station to again move the documents past the exposure station.
摘要翻译： 用于向狭缝扫描曝光站呈现文档的系统包括：第一流体储存站，其中存放用于存储文件的支架。 齿条包括多个凹穴，每个凹槽可以存储文件，该齿条可在垂直方向上移动。 流体用于将口袋中的文件部分地从储存装置中移动通过开口并与口袋的门和壁对准。 此后，门打开，与曝光站相关联的驱动器将部分喷射的文件移动通过扫描窗口。 然后将机架垂直地台阶以将另一个口袋与开口对准，并重复该过程。 暴露的文件移动到第二流体储存站，类似于第一流体储存站。 在该站处，通过开口抽出的流体将文件移动到机架的凹槽中，并且机架的垂直运动用于为每个文档提供单独的口袋。 存储站和驱动器中的流体流的反转可以在第二站的开口处与门配合使用，以使文档再次移动通过曝光站。

摘要： Apparatus includes a structure having a vertically disposed thin rectangular pocket into which the leading edge of a document is inserted by a roller arrangement. When the document is released by the roller arrangement it registers against the bottom wall of the pocket and a fluid stream provided in the pocket registers the document against a narrow vertical wall of the pocket. The wide walls of the structure are transparent and provide a view of the document which may be used in cooperation with xerographic equipment to produce copies of the document. Another fluid stream in the pocket is used to move the originally trailing edge of the document into engagement with the roller arrangement and the arrangement cooperates with a guide to move the document into a tray. The facing position of a collected document is inverted with respect to its facing position immediately prior to its being fed into the roller arrangement.

摘要： A system for presenting documents to a slit-scan xerographic exposure station includes a fluidic storage station having a housing in which a rack for storing documents is located. The rack includes a plurality of pockets in each of which a document may be stored, the rack being movable in a vertical direction so that any one of its pockets may be aligned with an opening in the housing. A fluid stream is used to move a document in a pocket aligned with the opening out of the storage apparatus and into engagement with transport apparatus. The transport apparatus includes a vacuum document drum which moves a document past the exposure station and, in one mode of operation, inverts the document prior to its return to a pocket at the station. In another mode of operation, the direction of travel of the drum is reversed after the document has been exposed and the document is returned without inversion. Another fluid stream is used to assist the return of an exposed document through the opening and into a pocket of the rack.
