DIVERSE-INPUT SYSTEM FOR ELECTROSTATICALLY REPRODUCING AND RECORDING INFORMATION This invention relates to copier/reproduction systems in general and, more particularly, to such a system which is adapted to accept many input forms of information to be reproduced.

Generally, copier/reproduction systems of the type adapted to accept an input such as a letter size original, book page or picture, incorporate a printer processing unit with a single input station that converts the information on the letter original, book or picture into corresponding light rays compatible as the processing unit's operative input. For complete reproduction capability, that is, for a system to utilize other input forms such as microfilm, automatic document feeding operation, video signals, alpha-numeric keyboard electronic signals, aperture cards and the like, etc., a printer processing unit must be combined for each form ofinput. Needless to say, the use of a separate printer unit for each form of input is costly and, the space necessary to accommodate separate printers is needlessly wasted. Therefore it is the principal object of the present invention to arrange copier/reproduction input units, a single printer unit and interface structure so that the printer unit is adapted for utilization for each of the input units.

Another object of the invention is to utilize a single printer unit in conjunction with multiple input units adapted to be readily attached to the printer unit for selectively presenting the printer unit with material-to-be produced originally provided in different forms.

Another object of the invention is to convert various forms of information to-be-reproduced into corresponding optical representations and to interface each of these representations with the imaging station ofa reproduction machine,

Still another object of the invention is to arrange a reproduction system having a single printing unit, a plurality of output devices such as, catch trays, sorters or finishing sta tions, and a plurality of sources of information arranged to provide individual inputs for the printer unit wherein the system may be readily conditioned for producing readable copy of the information presented to the printer unit.

The system invention may be accomplished by an arrangement which includes a reproduction printer unit adapted to receive imaging light rays and to convert the same to readable intelligence on support material such as sheets or web of paper; a plurality ofinput units each being capable of producing imaging light rays from a specific medium or form ofinformation, such as, video facsimile signals, microfilm, data processing information, a light scanning platen to support an original document or book page for one-to-one reproduction, aperture cards, opaque cards, microfiche, other microforms, various forms of computer output, such as tape, etc. and; an interface connection between the printer unit and each of the input units in order to effect the presentation of the output from each input unit as the input to the printer unit.

Other objects and advantages of the present invention will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings wherein:

FIG. I is an isometric view of a reproduction system embodying the principles of the present invention of utilizing a single printer unit and a plurality of imaging input units, a plurality of output devices and a plurality of record material inputs;

FIG. 2 is a plan view ofthe system shown in FIG. 1;

FIG. 3 is an isometric view, partly in section of the printer unit shown in FIG. I, with an optical system for producing imaging light rays for the unit and two paper input devices;

FIG. 4 is an isometric view of the reproduction system arranged to effect reproduction from a microfilm input unit and a one-to-one copier combined with an automatic document feeding device;

FIG. 5 is a plan schematic view oftwo reproduction systems remotely located and each connected by a cable adapted to carry transmitted electrical signals to an input unit associated respectively with the systems; and

FIG. 6 is an isometric schematic view of a reproduction system arranged to receive inputs of different forms from several remotely located places oforigination.

For a general understanding of a typical reproduction or printer apparatus to which the invention may be incorporated, reference is made to FIGS. 1, 2 and 3, and particularly FIG. 3 wherein various components of a typical printer system is schematically illustrated. For purposes of illustration, the printer unit to be described herein is of the electrostatic type and, in particular, a xerographic reproduction machine. As in all xerographic systems, a light image of an original to be reproduced is projected onto the sensitized surface ofa xerographic plate to form an electrostatic latent image thereon. Thereafter, the latent image is developed with toner material to form a xerographic powder image corresponding to the latent image on the plate surface. The powder image is then electrostatically transferred to a record material such as a sheet or web of paper or the like to which it may be fused by a fusing device whereby the powder image is caused permanently to adhere to the surface of the record material.

For purposes of the present disclosure, the xerographic reproduction machine, indicated by the reference numeral 10 is arranged as a self-contained unit having all of its processing stations located in one unitary enclosure or cabinet. The printer unit includes an exposure station at which a light or radiation pattern of a document D positioned horizontally on a glass platen is projected onto a photoconductive surface, such as a xerographic belt 12. Imaging light rays from the document D, as flash" illuminated by lamps 14, are projected by a first mirror 16, a projection lens 17 and another mirror 18 onto the belt 12, the focal plane for the lens 17, at a position indicated in FIG. 3 by the dotted line 19.

For purposes ofmore efficient flexibility and in accomplishing the objects of the invention, it is preferred that the optical path from he platen D to the focal plane 19 including the lens 17 with mirrors l6 and 18 on either side thereof be arranged so that the mirror 18 is mounted within the printer machine 10 and that the lens 17 and the mirror 16 be mounted in the optical input unit that supports the platen or object plane for the optical path. However, for some purposes it may be more flexible to provide each of the optical input units with a mirror 18 and to end the printer unit cabinet with a wall that is closely adjacent the image plane 19.

As an interface structure and for unobstructed optical projection, the side of the cabinet for the printer 10 is formed with an enlarged rectangular opening to permit the projection of image light rays from the lens 17 to the mirror 18. Similarly, the cabinet for the input unit supporting the object plane is formed with a corresponding rectangular opening that mates with the opening in the printer cabinet when the two cabinets are operatively joined together for copy/duplicating purposes. Suitable lighttight gaskets may be utilized adjacent the exterior of each opening in the cabinets in order to minimize the leakage of unwanted extraneous light. The positions of the lens 17 and the mirrors 16 and 18 relative to the platen and the image plane 19 are such that when an input cabinet and the printer 10 are operatively jointed, the focal plane 19 will be within the plane of the belt 12 and good optical transmission ofthe document image rays will be achieved.

The xerographic belt 12 is mounted for movement around three parallel arranged rollers 20 suitably mounted in the printer unit 10. The belt may be continuously driven by a suitable motor (not shown) at an appropriate speed corresponding to the discharge response of the photoconductive material that comprises the belt and the intensity of the imaging light rays from the document D. The exposure of the belt 12 to the imaging light rays from the document discharges the photoconductive layer in the areas struck by light, whereby there remains on the belt an electrostatic latent image in configuration corresponding to the light image projected from the document. As the belt continues its movement, the electrostatic latent image passes a developing station at which there is positioned a developer apparatus 21 for developing the electrostatic latent image. After development, the. powdered image is moved to an image transfer station whereat record material or a sheet of paper just previously separated from a stack of sheets 22 is held against the surface of the belt to receive the developed powder image therefrom. The sheet is moved in synchronism with the movement of the belt during transfer of the developed image. After transfer, the sheet of paper is conveyed to a fusing station whereat a fuser device 24 is positioned to receive the sheet of paper for fusing the powder image thereon. After fusing of the powder image, the sheet of paper is conveyed to an opening in the housing for the printer unit for accumulation or distribution of the sheets of paper as they are produced.

The sheets of paper may be separated from the stack of sheets 22 arranged in the printer unit 10 and fed from the top of the stack by means of a separator roll system 26 in timed sequence with the movement of developed latent images on the belt 12.

Further details of the processing devices and stations in the printer unit 10 are not necessary to understand the present invention. A detailed description of the processing stations and components along with the other structures in the printing unit 10 are adequately disclosed in the copending application Ser. No. 731,934 to Hewes et al. filed May 24, 1968.

The printer unit also is adapted to have positioned at one end thereof and operatively associated therewith a roll converter unit indicated by the reference numeral 30. The roll converter 30 is adapted to convert a relatively large roll of paper 31 into various sizes of sheets of paper by means of a cutter device 32 and a control system (not shown) arranged to control cutting and feeding ofthe individual sheets into operative cooperation with the separator roller 26 positioned within the printer unit 10. With this arrangement, precut sheets from the stack 22 of a specific size may be fed seriatim to the transfer station for the photoconductive belt 12 or, if it is desirable to utilize sheets cut from a supply roll of record material, say for example in the event that different size sheet are required for a production run of the unit 10, the operator need only inactivate the precut paper feeding mechanism and activate the roll converter unit with the cutting device for affecting the cutting and feeding of sheets to the transfer station for the printer unit. In accomplishing the objects of the invention, the roll converter unit is housed within its own cabinet which can be moved into and out of operative position relative to the printer unit. A slot formed in the rear panel of the cabinet for the printer may be made to mate with a corresponding slot formed in the roll converter cabinet in order to permit the movement of cut sheets from one cabinet to the other. Once inside the printer unit cabinet, the sheets fed from the roll converter unit are transported by the sheet moving devices for the stack 22.

As shown in FIG. 1 at the other end of the printer unit 10, there is positioned an output tray 40 arranged to receive sheets of paper as they pass through a slot 4| formed in a wall housing for the unit 10 The conveyor (not shown) associated with the fuser unit 24 is adapted to transport finished copy sheets through the slot and into the tray. in place ofthe output tray 40, a sorter or multiple sorter unit 42 may be positioned in order to receive sheets of paper from the unit 10. The slot 41 may also be utilized to direct fused finished copy sheets to various finishing stations such as staplers, binders, joggers, etc. Whereas the output tray 40 will accumulate a particular production run of the unit 10. the sorter units 42 are adapted to sort the individual sheets in accordance with a predetermined plan that may be programmed for the sorter unit 42. For versatility, the operator need only attach the output tray 40 to the printer cabinet, or bring the sorter units into operative engagement with the output conveyor for the printer unit.

1n FlG. 1 there is also shown two optical input units 45, 46 that may be utilized to effect individually, or by combined use, the exposure of the belt 12 at the focal plane or exposure station 19. The first optical unit 45 is provided with a suitable transparent platen upon which original documents of different sizes and forms may be positioned for illumination thereof. Details of such a unit were previously described in relation to FIG. 3 and like structure will be designated with the same reference numerals. A flexible platen cover C may be positioned to rest upon the top of the document being illuminated from below and within the unit housing. Within the cabinet for the unit 45, the illumination lamps 14 may be mounted and supplied with electrical power, and the mirror 16 may also be positioned to direct light rays through the sides of the two rectangular openings formed in the adjacent unit 45 and the unit 10. Preferably the projection lens 17 is also made part of the optical unit 45 and the mirror 18 remains apart of the pair unit 10, as shown in FIG. 2. 1n the event a system arrangement utilizes a mirror 18 for each imaging input unit so that the printer unit ends along the plane of the belt 12, the catch tray 40 or sorters and the fuser unit 24 must be arranged above the printer unit.

The optical unit 45 in being adapted to accommodate original documents, books or the like characterized by having standard print size may be considered a 1:1 image forming device. Besides a standard 8 /2 inches X 11 inches letter size original, the unit platen, mirror 16 and lens 17 is capable of accepting 12 inches X 18 inches side-by-side originals or 5 inches X 8 inches cards, or any other desirable size or shape of original. The resultant copy sheets which bears The same size of information to be copied may be cut in the roll converter 30 to match the sizes of the originals. By incorporating a suitable add-lens to the projection lens 17, which is capable of varying the magnification power of the lens, a larger document such as a two page original may be applied to the plate on the unit 45 for effecting a reduction of size of the informational area of the original upon a small size of copy paper.

The other optical input unit 46 is adapted to feed minidata cards 47 in the form of aperture cards, 3X opaque cards, microfiche or the like across a scanning station positioned with the unit. The data on the cards may be enlarged to desired magnification and directed to a mirror in the unit for projection by a lens out of the unit cabinet through an interface opening in the side thereof. A corresponding opening is formed in the cabinet for the printer 10 for permitting the impingement ofimage light rays upon the mirror 18.1n FIG. 2, the imaging light rays so produced are directed along the optical axis onto the mirror 18 turned to the position indicated by the dotted line 0 for exposing the photoconductor belt 12. The minicards 47, in the form of aperture cards are formed with suitable openings into which are secured film chips such as microfilm frames having information reduced to a size of between 12.x and 16x. 1f the cards 47 are of the opaque type, the minidata thereon, having been printed by a previous process, are generally of a size approximately one-third the size ofthe original information, unreduced.

In any event, with the use of either card form, a suitable automatic card pickoff and scanning system for presenting the minidata of each card in seriatim or, repeatedly for multiple copies thereof, may be utilized in order to accomplish a production run of the printer unit 10 for a predetermined number of cards placed in the unit 46. Such as automatic card pickoff and scanning system that may be incorporated into the input unit 46 is disclosed in the U.S. Pat No. 3,379,106 to Hewes et al. For scanning and projecting microfiche frames, the unit 46 may incorporate the microfiche handling mechanism disclosed in U.S. Pat. No. 3,372,627 to Murray et al.

Actuating and control means may be incorporated into the printer unit 10 and operatively connected to the units 45, 46 for imparting rotation to the mirror 18 in a direction or position, as shown. in FIG. 2, in order to receive and direct light rays from either of the optical input units 45, 46 to the image plane 19.

Alternatively, either of the units 45 or 46 may contain its own respective programming circuits for controlling operation of the printer unit 10. Such control may also effect the proper orientation of the mirror 18 and control either of the paper supply units, that is, the paper feeder apparatus 22, 26 or the roll converter 30. A control panel and housing 48 on the unit 45 may be utilized for this programming and control and may contain the conventional On-Off" switches; the number of copies selector switch; a copy counter indicator; a switch for the selection of paper feeder apparatus 22, 26 or roll converter 30 and the size of the sheets to be cut if the latter paper supply is to be utilized; the control for the sorter system 42 if one is to be in use and, distribution, that is, the number of copies for each distributee. Similarly, the unit 46 may include a control panel and housing 49 for these purposes.

Another arrangement of optical input units is shown in FIG. 4, wherein the printer unit has associated therewith an optical input unit 50 similar to input unit 45 but including an automatic document feed mechanism 52. The document feeder is arranged upon the top of the cabinet for the unit 50 and is adapted to feed in seriatim original documents across the platen for the unit 50 in order to affect a precollated production run of the printer unit 10 for a stack of documents placed in the document feeder 52. The unit 50 includes a projection lens system 17 and a mirror similar to the mirror 16 for directing image light rays from documents being fed, to the mirror 18 ofthe printer unit 10.

On the other side of the printer unit 10, there is show in H0. 4 another optical input unit 53 arranged to support a microfilm reel projection system 54 having an enlargement optical system for enlarging to full size the information on each of the microfilm framesv The unit 50 is provided with a control paneling and housing 55 similar to the panel 48 and may include specific document feeding control such as for number of copies per document. The unit 53 includes its own control panel and housing 56 which is similar to the panel 48 but including specific microfilm reel controls such as frame selection, fast wind or rewind, automatic frame advancing control.

Each of the units 50, 53 is formed with an opening in a side of the cabinet therefor, that is adapted to cooperate with corresponding openings formed in the printer unit 10 in order to permit the transmission of imaging rays from either of the op tical units 50, 53 to the photoconductor l2.

Another arrangement of optical input units is illustrated in FIG. 5 wherein there is shown two copying/duplicating machines 10, each coupled with transmitting and receiving devices 60 and 62, each coupled with transmitting and receiving devices 60 and 62 respectively, to form reproduction system capable of producing readable hard copy from information received by way of telephone cables or by RF signals. Each reproduction system may be operated in a different location such as distant cities or the various floors of a large office building and, are operatively connected together by a two way cable or RF link illustrated by the reference numeral 64. Each reproduction system is a duplicate of the other and is connected by suitable cables or RF links that will permit the transmission of video facsimile and control signals. While any number of reproduction systems may be employed, only two are illustrated and these are operatively arranged so that control signals and information to be copied can be transmitted and received in either direction. Since both reproduction systems are duplicates, only one will be described in some detail.

Each reproduction system includes a printer unit 10 in cooperative relationship with the optical input 45 previously described, and, an electrical-optical converter in the form of the transmitting and receiving facsimile apparatus 60 or 62, as the case may be. The unit 60. 62 is adapted, in one mode of operation, to convert input video facsimile signals into a corresponding optical representation of the information supplied in the signal. This may be accomplished by a CRT adapted to receive electric signals indicative of the information ofa document scanned by a flying spot" scanner of another CRT'in the other reproduction system and to effect flying spot" scanning upon the mirror 18 in the printer unit 10. in another mode of operation, the CRT in the unit 60, is adapted to scan a document positioned on a suitable platen for this unit and to produce corresponding video signals and to transmit these signals to the duplicate unit 62 in the other reproduction system. With both modes of operation, the electrical-optical converters or facsimile apparatus are adapted to produce video signals, transmit the same to remote locations and to receive video signals for converting the same to facsimile reproductions of documents being reproduced. Details of an optical unit type portrayed by the unit 60 may be found in the U.S. Pat. No. 3,149,201 to Huber et al. and therefore further details thereof are not necessary. As previously stated, the signals received by the unit 60 are generated from the similar unit 62 associated with the other reproduction unit.

The arrangement illustrated in FIG. 5 then has the capability of producing copies directly from the documents by virtue of the optical input unit 45 at 1:1 or other magnification The arrangement is also capable of reproducing information carried by way of a cable or an RF link in the form of video signals from relatively long distances and to present this information in graphical form suitable for reproduction by printer unit 10. The units 60, 62 may include their own specific controls for operation and also supervisory controls which integrate into the controls of each other and other similar facsimile units that may be employed in the arrangement of F IG. 5. Such controls are disclosed in the U.S. Pat. No. 3,303,280 to Fox et al. and further detailed disclosure thereof is not necessary for the present invention.

The arrangement is additionally capable of receiving inputs simultaneously from both units 45 and, 60 or 62, the combination 0 which is adapted to produce on a single sheet, representation from both informational sources. When an original is being scanned by the unit 60 while on the platen for the unit 45, the mirror 18 is moved out of the optical path. The system is also capable of transmitting information from an original placed on the platen for the unit 45 for reproduction thereof at a remote location at the same time the same original is being copied by the printer unit 10 located at the originating station. This may be accomplished by utilizing a mirror 18 that is semitransparent and capable of presenting an image at the exposure station 19 for the unit 10 while at the same time allowing the image to be received by the unit 60 and converted to a corresponding video signal for transmission to the unit 62.

Another arrangement of imaging units for reproduction purposes is illustrated in FIG. 6. In this arrangement, the printer unit 10 is combined with 1:1 document optical input unit 45 and an interface unit 70 which may be a character generator adapted to convert electromagnetic signals, such as video facsimile signals to graphic representations suitable for producing an image configuration on the photoconductor belt 12 in the unit 10. The unit 70 is provided with a mirror and a lens such as the mirror 16 and the lens 17 in the unit 45 and is formed with an opening in a wall of the cabinet therefor, thereby effecting cooperation with the corresponding opening in the unit 10 and the mirror 18. This cooperation, as in the other previously described arrangement, establishes an operative engagement between the signal-to-graphic interface unit 70 with the printer unit.

The interface unit 70 is illustrated as being coupled to two remotely located facsimile units 72, 74 by way of cables 76. Each of the units 72, 74 is adapted to scan optically original and to convert the resultant optical image to electric signals. In this function, the units 72, 74 are similar to the facsimile devices 60, 62 in the arrangement of FIG. 5. The electric signals produced by the units 72, 74 being indicative of the op tical images of the originals, are transmitted by the respective units to the interface unit for conversion of the signals into corresponding optical representations that can be utilized to produce electrostatic images on the belt 12.

The interface unit 70 is also operatively coupled by cables 78 to two remotely located alphanumeric transmitting devices 80, 82 each being provided with an alpha-numeric typewriter keyboard. Use of one of the units by an operator serves to produce signals indicative of the alpha-numeric characters selected by the operator on the respective keyboard. These signals are converted to alpha-numeric characters by the interface unit 70 in order to present corresponding optical images for reproduction by the printer unit 10. A tape recording device 84 is coupled into the cables 78 and may receive simultaneous recording when either of the units 80, 82 is operated in order to permit a latter playback for the interface unit. Any other previously produced tape may be utilized instead of those produced with the units 80, 82 in order to acquire hard, readable copy from the printer 10 of the material contained in the tape.

For still further versatility, the cables 78 are also connected to a voice recognition scanner 86 which is adapted to produce electrical signals indicative of audio transcription such as voice induced recordings. Such scanner may include an optical scanning device for converting recognized sound recordings into a corresponding optical representation and the into a video facsimile signal representative of the optical results. The video signal may then be transmitted and converted by the interface unit 70 into optical images suitable for reproduction as line copy by the printer unit 10. Incorporate with the units 70 may be suitable storage and retrieval systems having a computer that will use audiotape, videotape or even movie film as a storage form. Any number of different retrieval devices may be then utilized to recall stored information from the computer for print out purposes by the printer unit l0.

With the arrangements comprising the l:l optical input unit 45 in combination with: in FIG. 1, the minicard unit 46, in FIG. 4 the microfilm reel projection system 53; in FIG. 5, the transmitting and receiving facsimile system 60; in FIG. 6, the signal to graphic interface unit 70 and any one or all of the input devices thereto, there is provided standard copying/duplicating service in the form of the unit 45 and any one of a multitude of other services capable of accepting and handling other various forms of information for conversion to a form which can be utilized for producing hard readable copy.

Other arrangements of inputs to the printer unit 10 may be incorporated than those illustrated in FIGS. 1,4, 5, and 6. Fox example, in FIG. 1 the M optical unit 45 may be replaced by the microfilm reel projection system 53 thereby allowing the user full use of most types of miniaturized masters such as microfilm, microfiche, aperture cards and opaque cards in the event that a particular production run is to involve exclusively stored data material. in such an arrangement, the control panel 56 for the unit 53 may include additional controls which are effective to operate the respective units sequentially. Another arrangement would integrate either of the two miniature input form units 46, 53 with either of the facsimile systems 60 or 70 with some of the devices 72, 74, 80, 82, 84, and 86.

For any arrangement of input units, operative cooperation is assured as between the units and/or the printer unit 10 optical systems, by the physical association of the cabinets for the units, and the matching openings which permit the transmission of imaging light rays between the input units and the printer unit. Locking clamps may be provided on all the units for preventing the inadvertent movement of the unit during use and, interlock switches and alignment devices may be utilized on each unit for insuring proper optical alignment of all the optical structure involved and to terminate or suspend operation in the event misalignment or separation of units oc cur. For facility, each of the units are provided with caster wheels and locking brakes thereby aiding in the movement of the units into and out of cooperative engagement. The positioning of the optical input units may be reversed, assuming that units are available which are oriented as left-handed and right-handed. or only one input unit utilized and the printer unit positioned against an office wall. This latter arrangement has significant advantage if there is a shortage of office space.

With the printer unit fixed against a wall, each optical input unit can be applied as needed rather than arranging two input units in operative engagement with the printer unit.

From the foregoing it may be appreciated that the present invention allows the use ofa single reproduction unit in conjunction with a multitude of different optical input units, paper supply devices and paper output apparatus. it will be apparent that arrangements other than those described above may be devised without departing from the scope of the invention which is limited only by the accompanying claims.
