摘要： PROBLEM TO BE SOLVED: To efficiently shorten a medium processing passage to enhance the reliability of the processing passage and to reduce the size of the whole machine in a parallel printing system. SOLUTION: The printing system 10 is provided with a plurality of marking engines 12, 14, a paper feeding device and a medium outlet conveying part; a highway passage 24 for conveying documents at a first speed through the system; and a reverser 92 disposed between the highway passage 24 and at least one marking engine 12. The reverser 92 is constituted to selectively reverse and convey the documents at a second speed (slower than the first speed for image formation) through at least one marking engine 12 and to buffer the difference between the first speed and second speed (to prevent influence caused by the speed difference between the first speed and second speed).

摘要： A device for inverting a sheet along a path in an electric photographic printing machine. A gateless sheet inverter is provided in which a curved portion of a sheet path branch intersects a second portion of the sheet path to form a curved inverter throat. As the sheet is driven from the curved branch portion of the path into the throat portion the beam strength of the sheet causes the trail edge of the sheet to flip toward a second nip leading to the second sheet path. A pair of reversing rolls captures the lead edge of the sheet to be inverted and then reverses to drive the sheets out of the second nip formed by a tri-roll arrangement. A sheet having a radius of curvature equal to or greater than the radius of curvature of the throat will be guided along the throat baffle and fed through the second nip. To further assist in assuring the trail edge flips to the second sheet path an air knife can be added at the intersection of the path branches to assist in moving the trail edge into the second path branch. A fixed deflector can also be added and configured so that the trail edge of the sheet is guided into the second branch of the sheet path to increase the latitude of sheet curvature that can be handled by the device, the deflector further having a curved radius on the portion of the deflector contacting the sheet so that coated sheets are not damaged.

摘要： A relief device for the tamping mechanism (176) of an offset sheet set stacker. A sheet set stacker is provided having a plurality of retractable tamping mechanisms for alternately offsetting sheet sets within the stacker. Each tamping mechanism (176) is provided with a spring biased follower arm (206) which locks the tamping mechanism (176) in an operative position. A relief device in the form of an oblong pivot mount allows the tamping mechanism (176) to not only pivotally retract from an operative position but to also shift a slight amount transversely to the paper path process direction. This slight shift prevents a binding of the tamper against the just compiled sheet stack (214) and minimizes the occurrence of sheet stack disturbance.
