Definitions

  • This invention relates to a simple and low cost original document sheet feeder end ejector for a copier.
  • a lightweight and removable document handler is particularly desirable to allow conventional manual copying on the same copier. That is, for the document handler or feeder to be repositionable or removable to expose the existing conventional transparent copying window (known as the platen) of the copier. This allows the operator to manually place on the same platen other documents, such as delicate or odd sized documents or books.
  • U.S. Pat. No. 3,288,459 issued Nov. 29, 1966 to A. M. Hitchcock et al. and 4,052,054 issued Oct. 4, 1977 to W. R. Cardwell et al. disclosed an original document feeder for simultaneously feeding two original documents to be copied simultaneously.
  • the former illustrates and particularly describes in Col. 3, middle, through Col. 4, a document tray 2 with a reciprocating plate 54 adapted to hold two documents. It places the documents on a moving belt transport 3 for transporting the documents through a downstream scanning station 4. The ejection of the documents is subsequently by that transport belt into a tray 92.
  • U.S. Pat. Nos. 4,367,947 and 4,368,977 were issued Jan. 11 and Jan. 18, 1983, respectively, to N. K. Arter et al. (IBM). Both disclose a moving platen copier in which unidirectional rollers 34, 35, provide for ejection of a document from the moving platen in one direction of movement of the platen. Note, e.g. Col. 4, last paragraph through Col. 5, last paragraph. Particularly also noted are the last lines of this paragraph wherein a "movable scrapper blade or finger" is generally suggested, but is not further described or illustrated. Nor is even any suggestion made that the latter could be unidirectional or how it could or would operate.
  • a unidirectional roller 72 is disclosed in a manual assist document feeder in U.S. Pat. No. 3,941,473 issued Mar. 2, 1976 to William Goffe.
  • a unidirectional roller for a sheet stacker is disclosed in European Patent Application Publication No. 0 099 248 published Jan. 25, 1984 by R. W. Hughes et al.
  • a typical commercial document feeder for a copier with a stationary (vs. moving) platen has a document transport means such as an endless belt to transport original documents to the platen for copying, and then to eject them, by movement of the document transport belt over the platen from a position adjacent the platen, such as disclosed, for example, in U.S. Pat. No. 4,428,666 issued Jan. 31, 1984 to R. L. Phelps et al, and the numerous references cited therein.
  • U.S. Pat. No. 3,915,447 issued Oct. 28, 1975 to B. J. Perno discloses an endless belt document transport having a plurality of flexible tabs on the belt for deskewing and registering and gripping document sheets for conveyance over the platen.
  • exemplary document and copy sheet handling systems may be accomplished by conventionally actuating them by signals from the controller directly or indirectly in response to simple programmed commands and from selected actuation or non-actuation of conventional copier switch inputs by the copier operator, such as switches selecting the number of copies to be made in that run, selecting simplex or duplex copying, selecting whether the documents are simplex or duplex, selecting a copy sheet supply tray, etc.
  • the resultant controller signals may conventionally actuate various conventional electrical solenoid or cam controlled sheet deflector fingers, motors or clutches in the copier in the selected steps or sequences as programmed.
  • the present invention desirably overcomes or reduces various of the problems or limitations discussed above and/or in the cited references.
  • a preferred specific feature disclosed in this specification is to provide, in a document feeder for a copier with a stationary copying platen having document transport means movable towards and away from the copying platen of the copier for transporting original documents to the platen for copying by movement of said document transport means over the platen from a position adjacent the platen, wherein the improvement comprises:
  • holding means engageable and disengageable by movement of said document transport means, for holding the original documents against the platen in position for copying
  • said wiping means and said document transport means being adapted to prevent said wiping means from engaging further documents being transported onto the platen by said document transport means.
  • said holding means for holding the original documents against the platen for copying comprises a frictional wheel freely rotatable only in the direction of said movement of said document transport means towards the platen and vertically movable and positioned and biased to engage and press downwardly against a document transported thereto by said document transport means, said frictional wheel resisting, by said engagement and by non-rotation, the movement of a document in the direction of movement of said document transport means away from the platen, so as to separate a document from said document transport means during said movement thereof away from the platen, and then to hold that document against the platen;
  • said holding means for holding the original documents against the platen for copying further comprises a flexible lightweight light-reflective backing member extending over a document held against the platen by said frictional wheel and surrounding said frictional wheel and vertically movable therewith for providing a document imaging background;
  • said document transport means includes camming means for engaging and lifting said frictional wheel vertically away from said platen and away from said wiping means to provide said disengaging of said holding means, and for rolling said frictional wheel onto said document transport means so as to freely roll over a document on said document transport means during said movement of said document transport means towards the platen;
  • said document transport means comprises a document supporting tray reciprocally movable over but spaced above the platen and adapted to transport documents on top of said supporting tray, and said wiping means is mounted beneath said supporting tray;
  • said wiping means comprises a brush mounted adjacent the side of said document transport means adjacent the platen and extending from said document transport means sufficiently to make a document sweeping engagement with the platen as said transport means moves over the platen;
  • said brush dimensionally extends across the platen transverse the direction of movement of said document transport means.
  • FIG. 1 is a perspective top view of one embodiment of an exemplary document feeding apparatus in accordance with the present invention mounted on an exemplary commercial copier;
  • FIGS. 2-4 are similar (schematic) side views of the exemplary document feeder of FIG. 1, showing this same feeder in three different positions in its operation.
  • FIGS. 1-4 illustrate one example of the subject document feeder 10 for sequentially feeding document sheets to one example of a conventional copier 20 having a stationary conventional copying platen 22.
  • the entire document feeder 10 is simply and easily mounted on top of any conventional copier, when the existing platen cover or document handler is pivoted out of the way to expose the platen, as is conventionally provided for alternative manual document copying.
  • the operation of the document feeder 10 is shown particularly in FIGS. 2-4.
  • Documents may be loaded into a document transport 24 while that transport 24 is at one side of the platen 22.
  • the document transport 24 has a document holding tray 26 on its upper surface into which a document or documents may be easily loaded, and prealigned by a document rear edge stop or guide 28 and side guides 30.
  • the entire document transport 24 may then be linearly moved over the platen by means of its mounting guides.
  • these consist of two linear ball-bearing slides or tracks 32 and 34 extending across the front and rear ends of the platen.
  • These slides 32 and 34 provide for smooth and reasonably accurate reciprocal movement of the document transport 24, from its initial position at one side of the platen as in FIG. 2, to a position over the platen as in FIG. 3, and a return back along the same path to the initial position as in FIG. 4.
  • the slides 32, 34 are mounted at opposite ends to a left frame member 36 and a right frame member 38.
  • the left frame member 36 mounts over the left side, here the registration edge, of the platen 22 and the right frame member 38 has vertical end tabs which can fit into a slot in the upper cover of the copier, to the right of the platen, to provide an appropriate and easily removable mounting of the document feeder 10 to the copier 20.
  • the left frame member 36 may also have a hold-down bracket.
  • the reciprocal movement of the document transport 24 may be provided manually by an operator handle 40, or by an appropriate motor drive, e.g. the double helex reciprocal lamp drive of the "Xerox" "4000" copier and U.S. Pat. No. 3,775,008.
  • the tray 26 of the document transport 24, and all of its other moving components, with one exception, are spaced above the platen 22 at all times during the reciprocal movement of the document transport 24.
  • That one exception is a brush 42, which is mounted to the document transport 24, adjacent the front or platen side thereof and extending downwardly from the document transport 24.
  • the brush 24 extends laterally a sufficient width to extend substantially from the front to the back of the entire platen, extending between the slides 32 and 34.
  • the lower portion of the brush 24 engages and wipes across the platen 22 to remove and eject any documents on the platen, pushing all removed documents off of only the left side of the platen into a document ejection tray 44.
  • any and all documents previously placed on the platen are automatically ejected, without requiring any operator intervention or action or any separate drives or mechanism.
  • the subsequent documents to be copied are automatically fed onto the same platen 22. Yet there is no interference between these two functions with the present system.
  • the document wiping or brushing system and the rest of the document transport 24 are so designed that the brush 42 is prevented from engaging any of the further documents being simultaneously transported onto the platen by the document transport 24.
  • the brush 42 extends from beneath the tray 26 while the incoming further documents are transported on the top of the tray 26. These documents are not released and placed on the platen from the document transport 24 until the previous documents have already been swept therefrom by the brush 42. Likewise on the return movement of the document transport 24 the brush 42 slides back under the next document or documents being placed on the platen.
  • the brush 42 may be a known conductive, e.g. carbon fiber, brush to additionally provide platen static elimination.
  • a mounting shaft 46 is provided extending over the platen from the front and rear slides 32, 34. That is, from the outer, stationary, channel portions of these slides. Pivotally mounted to the shaft 46 over the platen are weighted arms 48, having frictional wheels 50 pivotally mounted at their outer ends. There are three such arms 48, each with a wheel 50, spaced over the platen here because this particular document feeder 10 is specifically adapted to simultaneously feed three small documents, such as envelopes, statements or checks. Each wheel 50 has a one-way clutch only allowing for rotation of the wheels 50 in the direction of the movement of the document transport 24 toward the platen, as illustrated by the rotational arrows in the drawings. Each weighted arm 48 independently biases and presses its wheel 50 downwardly against a document transported thereunder by the document transport 24. Each wheel 50 is positioned to centrally engage, in the direction of document movement, one individual document from the document transport 24.
  • the document transport 24 has a cam surface 52 at its front or platen-facing edge.
  • the cam 52 is adapted to engage and lift up all of the wheels 50 (which independently pivot up via their pivotally mounted arms 48) as the document transport is moved onto the platen under the shaft 46.
  • the wheels 50 then freely roll up the surface of the cam 52 and then roll over the surface of the tray 26 and over any documents therein as long as the document transport 24 is moving to the left, i.e. toward the platen.
  • the wrap spring, ratchet, or other conventional clutch associated with each wheel 50 prevents its reverse rotation.
  • the wheel 50 is non-rotatable in this direction of movement of the document transport 24 and fully frictionally resists the reverse movement of the document thereunder.
  • the wheels 50 are preferably urethane or other solid or foraminous high friction material, the document is held in position under the wheels 50 by this high frictional engagement.
  • the wheels 50 are now free to press the document down directly against the platen, and continue to hold the document in position on the platen until the entire document has been released by the tray 26 and is resting on the platen.
  • the downward and downstream angle of the arms 48 provides an increased normal force vector component increasing the pressure of the wheels 50 against the document as the document transport 24 is moved to the right.
  • the next or “new” documents are placed on the platen just after, and with the same movement of the document transport 24, as the previous or “old” documents were being removed by the brush 42.
  • the document transport is off to the right of the platen and the tray 26 is now empty for the loading of subsequent documents while the previous documents are being copied by the copier.
  • the copying may be initiated conventionally manually by a switch or foot pedal.
  • copying may be initiated automatically by a magnet on the document transport 24 operating a reed switch on the copier when the document transport 24 is reciprocated over the platen, by passage of the magnet over the reed switch.
  • the magnetic reed switch may be at the side of the platen and connected in parallel with the "START PRINT" button on the copier.
  • Skewing or mis-registration of the documents with this system is resisted by the plural parallel side guides 30 which, besides providing for compartmentalized loading of individual documents, also keep the edges of the document aligned as the document transport 24 is pulled away from the documents. Furthermore, by positioning each wheel 50 at a downstream area of the platen such that it engages a downstream area of a document centrally of the document, as shown, the frictional forces between the tray 26 and the document, as the tray 26 is pulled out from under the document, are providing a predominantly downstream pulling force tending to deskew the document.
  • the side guides 30 should, of course, be parallel to the direction of movement of the document transport 24 to aid deskewing or resist skewing. Wider or double rollers 50 may also be provided for this purpose.
  • the document retention and registration provided by the wheels 50 does not interfere with the ejection of the documents thereunder by the brush 42 on the next reciprocal cycle of the document transport 24. That is, the pushing of the documents downstream by the brush 42 (to the left side of the platen) is not resisted by the wheels 50, since they freely rotate in that direction of movement of the document thereunder. Before the brush 42 reaches or contacts the wheels 50 themselves, they are cammed up over the top of the tray 26 by the cam 52. Thus, for the final ejection movement of the documents from the platen the wheels 50 and their attached flaps 51 are lifted totally away from the platen, and out of contact with any document thereon.
  • the present system is particularly suitable for documents which are difficult to feed with automatic document feeders, such as envelopes of various materials, thicknesses and contents.
  • a semi-automatic document feeder is provided in which documents are individually loaded and fed.
  • a stack or stacks of checks, slips, invoices or the like may be placed in the tray 26 instead of individual documents. That is, with a front edge separating lip, or corners or front snubbers, or the like, for the tray 26, the present system may be utilized for sequential feeding of the topmost sheet from one or more stacks of sheets in the tray 26.
  • both the wheels 50 with their arms 48 may be readily repositioned, by sliding them along the shaft 46, to accommodate different numbers or sizes of documents. Preferably this would be accompanied by a corresponding repositioning, or removing, of side guides 30, so that each wheel 50 is positioned intermediately of each pair of opposing spaced side guides 30, as illustrated in FIG. 1.
  • the number and position of the side guides 30 on the tray 26 provides appropriate subdivisions into plural narrow trays for the plural document feeding to be provided.
  • the number of arms 48 and wheels 50 may be correspondingly increased or decreased.
  • a particular application of the present system is for generating three U.S. Postal Service forms 3547 per copier cycle. This is accomplished by simultaneously feeding three envelopes at a time, each with its forwarding address sticker thereon, to the copier platen with this system.
  • the platen is provided with a transparent forms overlay containing three sets of the appropriate additional printed information necessary to automatically generate three complete form 3547 postcard images containing both the original address and forwarding address information.
  • a reduction (optically reduced image size) copy is made of the composite image of the form and the envelopes, which are over the transparent areas of the form.
  • Each single copy sheet, preferably conventional letter size cardstock, containing these three composite images is then outputted from the copier through a slitter which cuts that single sheet into three postcards, as further described in the above-referenced commonly filed application by the same inventor.
