摘要:
Sheet item stacking apparatus wherein an eccentric drive oscillating articulated arm carries a friction wheel at one end, and wherein an angularly disposed cross link pivoted at one end to the arm and at the opposite end to a fixed support causes the oscillating arm to move both forwardly and rearwardly as well as from side to side effective to edge align incoming sheet items within an operably associated item hopper from which the items are "front" removable.

For use in ink jet printing apparatus, an insertable print/cartridge having an ink reservoir, at least two linear arrays of drop generating elements located in a parrallel relation, a support for coupling the ink reservoir and driver arrays and an orifice plate comprising a plurality of linear orifice arrays aligned in spaced relation over respective drop generating arrays. The orifice plate is an integral photofabricated element wherein the linear patterns formed by the orifice arrays are precisely parallel and have a precise predetermined spacing therebetween.

A modular, demountable toner fuser assembly for electrographic printing/copying apparatus wherein oppositely disposed adjustable tensioning members are coupled to a dead center linkage such that a pair of confronting pressure rollers operably associated with the dead center linkage can be moved relative to one another so as to provide suitable fusing pressure while being automatically instantly separables in response to any exigency e.g. items jams, tearing, crumpled paper or other nonfeed conditions.
摘要:
Non-impact offset printing apparatus providing repeatable top-to-bottom registration of printed matter transferred to cut sheet paper fed in the "portrait" direction by means of a timer-interposer mechanism which contacts the leading edge of each incoming sheet and times the entry of the sheet into the transfer point adjacent to the rim of the offset non-impact rotary printing apparatus effectively creating positive and accurate registration of all four margins of printed matter on each page.
摘要:
A modular high speed printing system for printing alphabetic and numerical information upon individual items or documents fed individually or in series through the modules. A feeder module performs accounting functions as to the number of documents processed, provides multiple or single mode document feeding and is adjustable to accommodate different size documents. The system also includes one or more printing modules for printing machine readable repetitive data, machine readable consecutive data, repetitive alphanumeric information and consecutive numeric information. A document receiver module adjustable to different size forms is also provided. The printing modules employ common document drive systems including an adjustable document end stop to permit horizontal placement of the information on the document. Vertical positioning of the information on the document is accomplished by means of adjusting the print mechanisms. The individual modules can be selected for operation in active or bypass modes and single cycle or flow feeding modes.
摘要:
A system and method are provided for determining ink jet printing system parameters by selecting an appropriate linearizing transformation for application to images to be printed on a printing system for a specific substrate. These transformations can be any transformation capable of being applied in graduated increments and having a corresponding incremental visual influence on the printed output. The present invention allows the user to determine multiple parameters for the printer, including for example, tone scale correction, determination of upper ink limits, amount of under color removal, and allows the user to identify the proper ink level for optimum quality of graphics and/or text printing.
摘要:
Continuous sheet item delaminating apparatus for electrographic drum printing/copying devices including a relatively flat horizontal coupler member having an upstanding vertical attachment portion and a u-shaped portion normal thereto. A plurality of curved, knife edged item picker fingers are mounted between the parallel legs of the u-shaped portion. The vertical attachment portion is pivotally secured to a rotatable crank rotated by a pulley driven from an associated synchronizer. A rocker-idler arm is fixedly pivoted at one end and is coupled at the opposite end to the coupler member such that rotation of the crank causes the picker fingers to follow a four bar coupler curve toward and away from the sheet item effective to lift the forward edge of the item off the drum and permit the item to fall by gravity onto a safe area for further handling.
摘要:
A rotary, self contained, unitary, modular detack mechanism for cantilever pivotal mounting wherein an epicyclic gear assembly operably connected to a continuously rotating source of motion is caused to advance a portion of adhesive material from a supply to a take-up receptacle over a peripheral projection on the mechanism in timed synchronism with a solenoid actuated cam follower effective to rotate the mechanism concurrently raising and lowering the same into momentary contact with and being detacked, stripper members straddling the mechanism strip the item from the adhesive.
摘要:
An indexing rotary actuator for applying the torque of a rotatable pivot arm to rotate a member between plural index positions. The forward stroke of the pivot arm drives a slider crank linkage through a four bar linkage to unlock the rotatable member and rotate the member to its next index position. On the return stroke of the pivot arm a spring biased locking arm on the rotatable member is interlocked with the actuator to lock the rotatable member in the index position. Interlock switches are provided to indicate when a rotated member is in a valid index position.
