Under the influence of the flowing light image, the uniformly charged photoconductive surface is selectively dissipated in the nonimaged areas to fonn what is commonly known as a latent electrostatic image.”
  • the latent electrostatic image is carried on the drum surface from the exposure station into the developing station C.
  • the developer material is caused to flow downwardly in contact with the upwardly moving drum surface under closely controlled conditions wherein charged toner particles are attracted from the developer mix into the image areas on the plate surface thus making the image visible.

  • the outer surface of the lower roll is heated by means of a horizontally supported radiant heat source 38 positioned in close proximity to the roll surface adjacent to the point at which the roll contacts the image bearing support material. As the heated roll is rotated in the direction indicated, the heated surface of the lower roll is pressed into intimate contact with the image face of the support sheet. Mechanical and heat energy transported from the roll surface to the support sheet to permanently bond the toner particles to the support material.
  • the fixed copy sheet Upon leaving the fuser, the fixed copy sheet is passed through a curvilinear sheet guide system, generally referred to as 39, into cooperating advancing rolls 40 and 41.

  • movable sheet guide 45, and it associated advancing rolls are prepositioned by the machine logic system to direct the individual sheets into the desired paper tray.
  • FIGS. 2-9 there is shown the sheet-handling apparatus of the present invention which enables a conventional xerographic machine to produce either simplexed or duplexed copies.
  • the mechanism to accomplish this unique result includes two substantially vertically aligned supply trays 52, 53 arranged to advance copy sheets into the xerographic transfer station D and a circular sheet path adapted to operatively connect the lower supply tray 53 to the upper supply tray 52.
  • a movable sheet guide, generally referred to as 45 is placed in the sheet path and is positionable, depending on the mode of machine operation selected, to direct xerographically processed sheets of material either into a final collecting station or into the upper supply tray 52.
  • the movable sheet guide 45 In the simplex mode of operation, the movable sheet guide 45 is positioned as shown by the solid lines in FIG. 1 in a position to direct copy sheets into catch tray 51.
  • the movable guide When duplexed copies are to be produced, the movable guide is moved to the position shown by the dotted lines in FIG. 1 and the upper tray conditioned to accept and restack simplexed copy sheets.
  • the upper tray is further conditioned to separate and forward sheets seriatim through the xerographic processing stations once again where a second image is placed on the backside of the sheet.
  • the conditioning of the sheet-handling equipment to accept and recirculate simplexed copy has generally been a manual operation.
  • the apparatus of the present invention now makes it possible to automatically hold and then reprocess the copy sheets between copy runs.
  • the individual supply trays 52, 53 are movably supported between the machine frames 91, 92 upon a set of rails 104 (FIG. 2) and are capable of being moved in a horizontal direction between a first operative position and a second trayloading position. In the operative position, the sheet trays are supported adjacent to the sheet-registering apparatus 24 wherein sheets forwarded from either tray are directed into a pair of sheet-registering rolls which align the sheets prior to them being forwarded into the transfer station.
  • the trays include a horizontal support platform 56 having a dependent, downwardly turned, vertical aligned front flange 54, a stationary side margin guide 59 and a movable side margin guide 58.
  • the stationary margin guide is rigidly afiixed to the support platform and has a vertically extended leg thereon.
  • the movable guide similarly has a vertical leg complimentary to that of the stationary side margin guide and is adapted to cooperate therewith to guide individual sheets forwarded from the trays along a predetermined path of travel into the sheet-registering apparatus 24.
  • the movable side margin guide is slidably carried upon the support platform and arranged to move laterally thereon making it possible to accommodate sheets of varying lengths upon the platform.
  • the tray is provided with an indexing scale for laterally positioning the movable side margin guide.
  • An L-shaped rear retaining member 64 is affixed to each of the vertical legs of the side margin guides.
  • the two rear retaining members associated with each supply tray cooperate to longitudinally position the stack upon the support platform.
  • the members are basically formed of an angular plate including a rear wall 60 and a flange 61 adapted to overlay in parallel relation the vertical legs of the side margin guide members.
  • Each of the side margin guides is provided with a stud (not shown) which protrudes through a horizontally slotted hole in the flange 61 of the rear retaining member 64 and is engaged by a thumb nut whereby each rear retaining member may be adjusted and tightened against the side margin guide.
  • a sheet separating and feeding means consisting of a pair of driven feed rollers 86 supported in a selfaligning manner within floating bearings secured to a shaft 87.
  • each feed roller is operatively connected to the drive shaft 89 by means of a clutch and pulley arrangement.
  • the prescribed sheet-feeding motion is translated to the rollers through the clutch and pulley arrangement in proper timed relation with an image on the drum surface wherein the advanced sheets and the image arrive at the transfer station at the same time.
  • each of the support platforms adjacent to the sheet-registering apparatus is unobstructed so that an uninterrupted path of travel is provided along which individual sheets of support material, which have been separated from the individual stacks, can be forwarded into the registering means.
  • Each retaining member 70 includes a main body 74 about which is rotatably mounted a hinged tab 75. The tab is pivotally mounted in the body upon a pivot rod 79.
  • a torsion spring (not shown) is wound about the rod and normally biases the tab against a stop aflixed to the body of the member to hold the tab in a horizontally extended position substantially perpendicular to the body of the retainer.
  • Each retaining member 70 is joumaled for rotation in the free end of the associated lifting arm 72 upon a pin 71.'
  • the retaining members 70 are designed so that their respective centers of gravity are located at a point wherein the freely supported member normally assumes a position with the tab normally extended in a horizontal position.
  • the tabs are repositioned when the lifting arms are elevated causing the hinged tabs to swing downwardly about the upwardly moving body 74.
  • the tabs continue to swing downwardly until they are removed from beneath the stack. Further elevation of the lifting arms moves the tabs upwardly in contact with the front margin of the stack until such time as the top of the stack is cleared.
  • the biasing spring acting in conjunction with the downwardly pulling weighted end 75 of the tab forces the tab to move rapidly back into its normal horizontally extended position.
  • the extended tabs engage the top sheet on the stack.
  • the actuator arms are allowed to continue to swing down until they come to rest once again against stops 124 so that the retaining members, and their associated lifting arms, hang in a suspended manner upon the stack to support the stack in sheet feeding alignment as shown in FIG. 6.
  • the topmost sheet in the stack is first separated from the main body of the stack by forming a separating buckle in the sheet and the sheet then forwarded to subsequent sheet-handling means within sheet-registering apparatus 24.
  • the feed rollers 86 are rotated in a direction to cause the leading edge of the topmost sheet in the stack to be moved rearwardly from beneath the front edge retaining members 70.
  • the trailing edge of the sheet is held stationary by the rear walls 60 in rear retaining members 64 so that a separating buckle is formed longitudinally across the sheet.
  • the suspended front retaining members 70, and their respective lifting arms, at this time drop down into supporting engagement with the main body of the stack.
  • Drive shafts 89 associated with the two feed roller assemblies 85, are driven from a main programmer shaft 101 rotatably supported in the sheet-registering apparatus 24.
  • the programmer shaft is, in turn, driven in timed relation with the xerographic drum by means of the main machine drive (not shown) to coordinate sheet advancement with the processing of an image on the drum surface wherein the image and the copy sheet move into transfer station D in synchronous timed relation.
  • a first original is placed upon the platen 14 prior to the duplex mode of operation selected.
  • Selection of the duplex mode of operation causes a solenoid SOL1 (FIGS. 2, 3) to be energized pulling down link 201.
  • the downward motion of the link causes the lever arm to be rotated about stud 199 forcing flexible member 203 into biasing contact with a crank arm 204.
  • the crank arm 204 is provided with an arcuateshaped elongated hole 205 having a notch (not shown) machined in the bottom wall thereof.
  • a dependent arm 207 on the cam follower carried a drive pin 206 which is arranged to pass through the elongated slotted hole provided in the crank arm.
  • This initial rotation of plate 220 to a latch position conditions the upper tray to accept and restack sheets supplied from the lower tray which have been xerographically processed to produce an image on one side thereof.
  • movable guide 45 (FIG. 1), positioned in the circular sheet path, is pulled downwardly to direct sheets fed along the sheet path directly into the upper tray.
  • the upper supply tray feed rollers are elevated out of the sheet feed path to permit sheets to be expelled from the movable guide directly into an upper tray in an unobstructed manner.
  • the movable guide 45 is pivotally mounted about a shaft 50 and normally held in an up position by spring means. The movable guide is driven from the normally up position to a down position by means of actuator link 228 (FIG. 2).
  • Sheets forwarded from the lower tray are registered in the register stop rolls and then passed through transfer station D to the xerographic processing stations where a first image is placed upon the copy sheet.
  • the copy sheet advanced by means of the heretofore described sheet-advancing rolls into the upper supply tray.
  • Delivering a simplex sheet to the upper tray is not in itself sufficient to insure that the sheets will be properly stacked and aligned prior to the start of the duplexing operations. It has long been known that improperly stacked sheets are the cause of misregistration and misfeeding of sheets resulting in the paper jams and in extreme cases of machine breakage.
  • the upper tray therefore is provided with means to receive and restack the simplexed sheets delivered from the lower supply tray.
  • the sheet-restacking apparatus associated with the upper supply tray 52 is shown in greater detail in FIGS. 4 and 5.
  • the restacking fundamentally consists of two front margin aligning members or joggers 245 and side margin joggers generally referred to as 257, both of which are driven by means of crank arm 204.
  • the front joggers are moved upwardly into contact with the front margin of the sheet forcing the sheet into registration with the backwall 60 of the supply tray.
  • two side joggers move into contact with the side margin of the sheet to laterally align the sheet within the tray.
  • the front joggers 245 are secured to a shaft 248 and the shaft rotatably supported in the machine frame (not shown) below the level and a bit forward of the open end of the upper supply tray 52.
  • the shaft is coupled to the crank arm 204 by means of an extension spring 251 pinned to the crank arm. Extension of the crank arm during any reciprocating cycle causes the spring to pull a coupling 250 in a clockwise direction rotating shaft 248 in a counterclockwise direction.
  • the front joggers are thus raised from a near horizontal position below the level of the tray to a sheet-engaging vertical position as shown in FIG. 4 to force the sheets rearwardly into registration against the backwall 60 of the tray.
  • the front joggers are permitted to be moved by the crank arm a greater distance than required to move the sheet into contact with the rear wall 60.
  • the pressure imparted by the cam system is regulated by the dampening action of the spring so that the spring is deformed before any damaging forces are transmitted to the copy sheets.
  • the rear end of the crank arm 204 is operatively connected to a bail 255 which is joumaled between the machine frames upon shaft 258 and which extends horizontally beneath the upper supply tray 52.
  • the left-hand end of the bail shaft is afl'lxed to a link 256 and the link rotatably secured in the crank arm 206 wherein the bail swings upwardly as the crank moves to its fully extended position.
  • two vertically extended rods 259 slidably supported within individual housings 260.
  • the housings are mounted adjacent to the side margin guides in the cutouts provided upon the supply tray platform 56.
  • the vertically extended rod is arranged to pass through both the housing and the support platform and rides freely in contact with the bail carried beneath the tray platform.
  • FIG. 5 illustrates the internal arrangement of the rod within the individual housings 260.
  • the rod is supported within the housing frame and has an inverted truncated member 261 af fixed to the center portion thereof.
  • a compression spring 262 is secured between the top of the housing and on the truncated member and acts to hold the vertical rod in biasing contact with the bail 255.
  • a flexible bar 263 is locked at one end to the housing by means of a clamp 264 (FIG. 4) and carries a vertically extended side margin jogger 246 on the free end thereof. The flexible bar rides in contact with the truncated member and is flexed inwardly towards the side margin of the upper supply stack as the rod is raised by the bail.
  • the two side joggers are adapted to move in concert into contact with the sheets to position the sheets therebetween in proper sheet feeding alignment.
  • the restacking force is transmitted through a flexible member which prevents sheetdamaging forces from being imparted from the drive mechanism to the copy sheets.
  • the programmer shaft moves through one complete revolution for each xerographic processing cycle and each sheet feeding cycle.
  • the crank is also controlled by the programmer shaft motion so that one reciprocating cycle of the crank is produced for each rotation of the programmer shaft. Because the motion of the individual joggers is physically linked to the crank arm the joggers will act to align each individual sheet fed into the upper tray during duplexing operations thus insuring that the resultant stack is properly maintained in a condition wherein sheets are able to be once again fed through the xerographic processing stations.
  • cam 213 Upon completion of the restacking operation, cam 213 is permitted by the machine logic to make at least one more complete revolution.
  • a second solenoid SOL-2 is energized pulling the floating arm 271 (FIG. 6) inwardly towards the solenoid body.
  • a universal member 272, passing through the floating arm, is rotatably mounted in a fixed position on vertical shaft 273. As can be seen, when the solenoid is energized the universal member is pulled in a counterclockwise direction towards the solenoid.
  • One end of the follower arm 208 is provided with a flange 274 which is moved downwardly as the follower traces the low side of the cam profile.
  • the universal member 271 When the flange is in the low position, the universal member 271 is able to be pulled over the flange by the solenoid. As the follower starts back in an upward direction during a subsequent rise portion of the cam cycle, the flange is brought into contact with the bottom of the universal member. Further upper movements of the flange causes the universal to push against a fixed bushing 275 secured to shaft 273 lifting the shaft. 7
  • the bottom of the vertical shaft 273 is pinned to a link 278 which, in turn, is pivoted about a stub shaft 279.
  • the stub shaft is held in a stationary position in mounted block 280 which is secured to the machine frame.
  • the other end, or top of the vertical shaft 273 is pinned to an actuator arm 283 and the arm rockably supported by stub shaft 284 secured in mounting block 285.
  • actuator am 283 is swung in a clockwise direction as shown in FIG. 6 forcing a dowel pin 288 secured thereto into contact with a horizontal slide member 290 slidably supported in the upper tray.
  • Slide member is slidably mounted in the downwardly turned front flange 56 of the upper tray platform below the level of the stack and is adapted to reciprocate in a horizontal direction.
  • the slide 290 is biased into contact with dowel 288 secured in arm 283 by means of an extension spring 307.
  • a pin 309 is staked to the upper tray platform flange and passes through a slotted hole 308 provided in the slide.
  • a second pin 310 is similarly staked to the slide member and the extension spring supported therebetween in a working position so as to urge the slide member against dowel 288.
  • a manual slide actuator 315 is provided at the opposite side of each tray which is affixed to the slide. If for some reason the retainer fails to engage the stack properly,
  • the operator simply pulls the actuator laterally to recycle the retainers into proper alignment.
  • both solenoids SOL-l and SOL-2 are deenergized.
  • Deenergization of solenoid SOL-1 allows pin 206 to once again ride in contact with the top surface of slotted hole 205 in the crank arm.
  • arm 202 is moved upwardly unlatching movable plate 220 and the plate allowed to return once again to its normal home position thus placing the upper feed roll assembly in contact with the top of the stack and returning the movable sheet guides to the up position wherein sheets are capable of being fed from the upper tray through the circular paper feed directly into catch tray 51 (FIG. 1).
  • the operator places a second original on the copyboard and starts the upper tray sheet feed operations.
