Definitions

  • This invention relates to a novel arrangement for recirculating originals through a photocopy machine. More particularly the invention relates to an improved multiple copy arrangement for photocopy machines whereby an original may be selectively recirculated along one of a plurality of possible original sheet feed paths.
  • Some known types of photocopy machines provide means for automatically recirculating an original through the machine so as to successively move the original through an illuminating station and thereby automatically obtain a desired number of repeat copies of the same original.
  • Each such photocopy machine is provided with a single effectively closed loop original sheet feed path which can accommodate originals having variable lengths up to a predetermined maximum.
  • One difficulty associated with this conventional type of original recirculating arrangement is that it takes just about as long to obtain a given number of automatic repeat copies of a relatively short-length original as it does to obtain the same number of automatic copies of a relatively longlength original. This condition is imposed by the fact that all originals, short or long, must travel along the same single recirculating sheet feed path.
  • the primary object of the instant invention is to make possible a photocopy machine having an automatic repeat copy arrangement which will reduce the time required to produce a given number of repeat copies-of a relatively short-length original.
  • Another object of the invention is to provide an automatic repeat copy arrangement for a photocopy machine whereby an original that is to be automatically copied several times may be recirculated through one of a plurality of original sheet feed paths.
  • Another object of the invention is to provide a sheet handling system for a photocopy machine whereby an original to be copied may be moved along one of a plurality of recirculating paths having different effective lengths.
  • Another object of the invention is to provide a novel original sheet handling system for a photocopy machine whereby a given original that is to be automatically copied a given number of times may be recirculated through a selected one of a plurality of possible feed paths, the particular feed path followed being dependent on the length of said original.
  • a further object of the invention is to provide a novel automatic repeat copy arrangement for a photocopy machine whereby a given original is sensed as to a physical condition thereof and is then recirculated through a selected one of a plurality of recycling original sheet ice feed paths, the selected path depending on the sensed condition of said original.
  • FIG. 1 is a diagrammatic sketch illustrating the concept of the instant original sheet feed path arrangement.
  • FIG. 2 is a cross sectional side elevational showing the structural nature and arrangement of the instant apparatus for recirculating an original through one of a plurality of original sheet feed paths.
  • FIG. 3 is a fragmentary front elevational sectional view taken along section line 3-3 of FIG. 2.
  • FIG. 4 is a partial front elevational sectional view taken along section line 44 of FIG. 2.
  • FIG. 5 is a fragmentary side elevational view in partial section and illustrates the two operative positions of the path selection gate.
  • FIG. 6 is a partial front elevational view taken along section line 6-6 of FIG. 2.
  • FIG. 7 is a sketch illustrating a circuit diagram and related control apparatus associated with the instant device.
  • FIG. 1 is a diagrammatic sketch illustrating the nature of the instant multiple recycle path arrangement.
  • an original is being manually fed into the machine moves along an initial portion 10 of a main feed path 11 and is then directed towards and through the terminal portion 12 of said main path to the outlet station of the machine.
  • the original is illuminated by well known means (not shown) at an illuminating or irradiating station 13 prior to moving to said outlet station.
  • This type of operation and arrangement is conventional in nature and need not be further discussed here.
  • Means are provided for automatically recirculating an original back into the main feed path 11 when it is desired to produce several copies of the same original, such means including a first gating means 15 that may be conditioned so that the original after passing the illuminating station 13 will be recycled along a path indicated at 16 so as to enable the original to be conducted back through the illuminating station a desired number of times.
  • a second gating means 17 is provided so that an original may take one of two possible feed paths in being recirculated through said illuminating station. Gating means 17 is normally set in a first position so as to direct the original along a relatively short recirculating feed path, as indicated at 18, but may be set to a second position by a solenoid 19, FIG.
  • a sensing means is provided for sensing the length of an original and for accordingly setting the gating means 17 to the proper position; this sensing means including a pair of normally open electrical switches A and B that are operatively positioned along the sheet feed paths, as shown in FIG. 1.
  • the switches A and B are located a predetermined effective distance apart so that when an original which is longer than this distance is initially recycled switch A will still be closed by the time the leading edge of the original closes switch B and under these conditions a solenoid will be energized through suitable circuitry so as to shift the gating means 17 and direct the original along said relatively long recirculating sheet feed path indicated at 20.
  • a solenoid will be energized through suitable circuitry so as to shift the gating means 17 and direct the original along said relatively long recirculating sheet feed path indicated at 20.
  • solenoid 19 will not be energized and this relatively short original will follow along the short original sheet feed path indicated at 18.
  • FIGS. 27 illustrate one specific embodiment of the instant invention which provides a multiple recycle path arrangement corresponding to that generally described above in connection with FIG. 1. Only that much of the structure of a photocopy machine which is pertinent to the instant recycling apparatus are shown in the drawings and it will be understood that unless otherwise'stated the various parts illustrated may be constructed, supported and/ or arranged in any suitable manner well known in the art.

  • the gating member is pivotable between a normal position and an actuated position as shown respectively by the dotted and solid lines in FIG. 5 so as to determine whether an original that is being recirculated will move along a relatively short recycle path around feed roll 75 (corresponding to arrow 18 of FIG. 1) or along a relatively long recycle path around feed roll 45 (corresponding to arrow 20 of FIG. 1).
  • An arcuate guide-plate mounted on said ,plate 72 cooperates with the closely adjacent cyclindrical surfaces of roll 75 so as to guide an original that is to follow along the relatively short feed path back into the nip between feed rolls 74 and 75.
  • another cooperating pair of parallel guide plates 121 and 122 are mounted on and between said side frames 32, 33, the upstream end of these plates being slightly flared so as to facilitate the entry therebetween of the leading edge of an original that has moved past the gating member 110, as indicated by arrow 123 of FIG. 5.

  • the limit of counter clockwise movement here being determined by engagement of the crank arm 141 with a stud 144 that is fixed to the machine frame.
  • the coil spring 143 is elfectively stronger than the spring 136 so that the recirculating gating member 100 is normally held in the inoperative solid line position shown in FIG. 7 whereby any original that is fed onto the machine moves through the illuminating station only once as indicated by the arrow 11 of FIG. 1 and thus only one copy of this original is produced.
