    Abstract: A multimode document handling apparatus and reproducing apparatus containing same are described wherein the document handling apparatus comprises an upper frame portion pivotally mounted along its rear edge to a lower base frame portion to provide open and closed positions of the upper frame relative to the lower frame. The lower frame contains a substantially horizontal imaging platen and document transport defining a generally horizontal document transport path. The upper portion contains a vertically inclined document loading chute the lower exit portion of which intersects the generally horizontal document transport path. The document loading chute includes a gate to permit loading of successive copies in the chute while preventing it from being fed as the preceding document is being copied. The device makes single copies by inserting a document into the chute and multiple copies by reversing the direction of the transport rolls to drive the document after having once been copied back across the platen in the horizontal path past the exit portion of the chute to be transported forward again across the imaging platen. At the same time in this multicopy mode the chute can be used as a wait station for insertion of the next document to be copied. The chute is also used as a wait station during the stream feeding of successive documents. To copy pages of a book, the upper frame portion is pivoted up and the book is placed on the transport rolls which transport it across the imaging platen.

    Abstract: PROBLEM TO BE SOLVED: To provide a photoconductive member which optimizes the length of a photoconductive belt and utilizes the length of the belt to the maximum to print a copy. SOLUTION: The photoconductive member 10 for use in a single pass multi-color printing machine includes an inter-seam zone 92 having a physical seam. The inter seam zone includes one (89) of a plurality of image-on-image registration marks. A plurality of interdocument zones 90 and 84 is also included on the photoconductive member wherein process control marks are formed. While the inter-seam zone is used for monitoring image-to-image registration, the process control marks are monitored to adjust the timing of the printing machine so that copy media synchronizes with an asynchronous placement of the images on the photoconductive member 10.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus or a method for controlling and/or adjusting the lateral position of one or more belts in a printing system in order to avoid processing interruptions or delays, or the like. SOLUTION: The belt is generally moveable in a process flow direction within the printing system, wherein a lateral direction extends substantially along the belt and substantially perpendicular to the process flow direction. The apparatus includes: a roller assembly for engaging at least a portion of the belt and extending laterally across the belt; a pair of laterally spaced support arms each rotatably supporting opposed ends of the roller assembly, and being pivotally coupled to the printing system for movement about a pivot axis extending substantially in the lateral direction; and an actuating assembly for pivotally moving at least one support arm about the pivot axis. The pivotal movement pivots one support arm relative to the other. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract translation: 要解决的问题:提供一种用于控制和/或调整打印系统中的一个或多个皮带的横向位置以避免处理中断或延迟等的装置或方法。 解决方案:皮带通常可在打印系统内的处理流动方向上移动,其中横向方向基本上沿着带延伸并且基本上垂直于工艺流动方向延伸。 该装置包括:辊组件,其用于接合带的至少一部分并横向延伸穿过该带; 一对横向间隔开的支撑臂,每个支撑臂可旋转地支撑辊组件的相对端,并且可旋转地联接到打印系统,以围绕基本沿横向方向延伸的枢转轴线运动; 以及用于围绕枢转轴线枢转地移动至少一个支撑臂的致动组件。 枢转运动使一个支撑臂相对于另一支撑臂枢转。 版权所有(C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a photoreceiving belt tension system by which the tension of a belt being in a belt steering operation is reduced and also excellent color positioning is attained. SOLUTION: A non-elastic tension mechanism setting and controlling a tension roll system with a photoreceiving body belt module acts on at least one of a pair of rollers about the periphery of which the photoreceiving body belt is entrained thereby keeping practically uniform tension even for the various total length of the belt.
