摘要： A device for rotating by a small angle, documents placed on an imaging device platen, for improved skew angle registration during imaging. An imaging device provided with a platen cover for covering the imaging platen of the imaging device includes document engagement member rotatably supported on the platen cover, between the imaging platen and the platen cover when the platen cover is in a closed position with respect to the platen of the imaging device. The document engagement member has a document contacting surface providing substantially non-slipping engagement of the document engagement member with documents placed on the platen when the platen cover is closed. An arrangement is provided for rotational adjustment of documents placed on the platen, at an externally accessible surface of the platen cover, and coupled to the document engagment member, for rotating the document engagement member through a small angle increment, and by consequence, documents engaged thereto, with respect to the platen.

摘要： A document handling system particularly suitable for electronic imaging by sequentially feeding uppermost document sheets stacked in an input tray to be imaged in forward serial order at an imaging station and restacked collated in an output tray, with a short and compact "U" shaped common document feeding path also providing the majority of a duplex document feeding path for returning duplex document sheets imaged on their first sides back to the imaging station for imaging their second sides. The input and output trays are in a space saving closely superposed relationship defining a protective confining inverter chute space therebetween within which the duplex document sheets may be fed out over the output tray by a dual mode reversible output sheet feeder at the "U" shaped path output and then reversed to feed back through a short linear duplex document feeding path into the entrance of the same "U" shaped document sheet feeding path for simplex document sheets to provide a duplex loop path.
摘要翻译：一种特别适用于电子成像的文档处理系统，通过在成像站顺序地将堆叠在待成像的输入托盘中的最上面的文档片材顺序地馈送到成像站，并将其重新打包在输出托盘中，具有短而紧凑的“U”形共同文档馈送路径还提供大部分双面文件馈送路径，用于将在其第一侧上成像的双面文档片材返回到成像站用于对其第二侧成像。输入和输出托盘处于节省空间的紧密关系中，限定了两者之间的保护限制的逆变器斜槽空间，其中双面文件纸可以通过在“U”形路径处的双模式可逆输出片材进给器在输出托盘上被送出输出，然后反向，通过短的线性双面文档馈送路径反馈到用于单面文档片的相同“U”形文档片材馈送路径的入口，以提供双工循环路径。

摘要： A copying apparatus with a document copying platen, including a substantially uniformly light reflective platen cover for holding documents against the platen, and including document drive wheels having light reflective constant width surfaces partially extendable through fixed apertures in the platen cover towards the platen. The fixed apertures in the platen cover are wider than the drive wheels to allow their limited transverse movement. Light reflective shields having an aperture the same width as the wheels are mounted in the platen cover so that each wheel extends through a light shield aperture with each light shield closely fitted to both sides of a wheel. Each light shield is movable transversely together with its wheel, but each light shield constantly overlies its fixed aperture in the platen cover irrespective of this transverse movement to constantly present a substantially uninterrupted light reflective surface over the platen together with the wheel.
摘要翻译：一种具有文件复印台的复印装置，包括用于将文件夹持在压板上的基本上均匀的光反射压板盖，并且包括具有光反射恒定宽度表面的原稿驱动轮，其通过压板盖中的固定孔部朝向压板延伸。压板盖中的固定孔比驱动轮宽，以允许其有限的横向移动。具有与车轮宽度相同的孔的光反射屏蔽件安装在压板盖中，使得每个车轮延伸穿过遮光孔，每个遮光板紧密地配合到车轮的两侧。每个遮光罩可与其轮一起横向移动，但是每个遮光罩都不断地覆盖在压板盖中的固定孔上，而与横向移动无关，以便在滚轮上始终呈现基本上不间断的光反射表面。

摘要： A digital scanner includes a multipurpose registration member that has a document registration edge locate surface, a carriage horizontal locate surface, a carriage vertical locate surface, and a platen locate surface. The platen locate surface provides registration for a transparent platen and the document registration edge locate surface provides registration for a registration edge member. The carriage horizontal locate surface and the carriage vertical locate surface provides registration for a scanning carriage which abuts the slide pad. Also, the multipurpose registration member includes a document handle locate surface to registration a document handler. The inclusion of these locate surfaces on a single registration member enables efficient assembly, without extraneous manual adjustments, of a digital scanner having proper registration.
