  • Controls conveniently mounted upon a panel 15 control the starting and stopping, the selection of number of copies and the like.
  • the present machine is of the electrostatic type utilizing a continuous roll of copy sheet paper coated with a sensitizing material such as zinc oxide and which is subjected to an electrostatic charge just prior to exposure.

  • the sheet subsequently passes into a developer tray having a liquid vehicle with suspended colloidal particles of pigment, or toner, which is attracted to the charged areas for development of the image.
  • the copy sheet is discharged from the machine.
  • a roll 20 in the form of a continuous web of photocopy paper 21 is mounted in the lower part of the machine.
  • the web passes upwardly between web drive rollers 22 into a cutter 23 having a fixed blade 24 and a rocking blade 25.
  • the cutter now indicated at 31, is passed into a turnaround 32 where the sheet undergoes a change in direction.
  • the turnaround From the turnaround the sheet passes into a charging unit 34 which is connected to a suitable source of high voltage (not shown). From the charging unit the sheet passes between a pair of constantly driven rollers 35 and into an exposing station 36.
  • an illuminating station 40 Optically coupled to the exposing station by a lens 37 and mirror 38 is an illuminating station 40 which is traversed by the original document upon movement of the table and which is illuminated by lamps 41.
  • the sheet moves into engagement with a second constantly running pair of rollers 45 into the developer tray 46 which contains the colloidal suspension of toner.
  • the sheet passing through the developing tray curves upwardly into engagement with a pair of expeller rollers 47 which discharge the sheet into a suitable collection tray 16 (FIG. 1a).
  • the cutter 23 includes a fixed blade 24 which extends the width of the copy sheet and a cooperating rocking blade is 25, the movable blade, in its open position, being closely spaced and parallel with respect to the sheet to be cut and arranged at a shallow angle so as to produce a progressive out along the width of the sheet with only a limited amount of rocking motion.
  • the cutter frame indicated generally at 50 is made up of hollow end pieces 51, 52 which are interconnected not only by the fixed blade member 24 but by a channel shaped crosspiece 53. Also extending the length of the frame is a paper guide 54 which, together with the fixed blade member 24, forms a convergent entryway 55 for the entry of the web from below.
  • a rocking yoke 60 is provided extending the length of the frame and having stubshafts 61, 62 at the ends thereof.
  • the stubshafts are received in bearings 63, 64 which are resiliently engaged by springs 65, 66.
  • set screws 67, 68 are used in opposition to the springs.
  • the longitudinally extending yoke 60 is reinforced by a channel member 69 which is riveted to it to form a backbone.
  • the blade is additionally offset at the remote end (FIG. 7), so that cutting of the web takes place progressively from one end to the other.
  • the movable blade is preferably bent at the end as indicated at 70 (FIG. 4) to provide an arcuate lip 71 (FIG. 5 and 5a) which rides upon, and never leaves, the end of the fixed blade. Consequently this insures a sure start" of the blades into cutting engagement free of any peak load under all conditions even when the adjusting set screws 67 and 68 are not in precise adjustment.
  • a blade driving mechanism for oscillating the blade through a small angle including a single revolution clutch which drives an eccentric which, in turn, drives an arm connected to the blade yoke and with means for triggering the single revolution clutch by movement of the table in accordance with the length of the original document so that the copy sheet is severed at a length corresponding to the length of the original document.
  • the cutter driving assembly is mounted in a subframe 80. Extending outboard of the subframe is a driven pulley of the cog type indicated at 81 which is driven by a cog belt 82 trained about a drive pulley 83 which is coupled, by means not shown, to a drive motor M.
  • a single revolution clutch 85 Journaled on the axis of the pulley 81 between the frame plates is a single revolution clutch 85 having a clutch output gear 86 which meshes with an idler gear 87 which, in turn, drives eccentric drive gear 88.
  • a crank or eccentric 90 Connected to the shaft of the gear 88 is a crank or eccentric 90 which engages a slot 91 formed in an arm 92 which is keyed to the stubshaft 62 which serves to rock the yoke mounting the cutter blade.
  • the clutch includes an input member 100 connected to the input pulley 81 and having a drive hub 101.
  • a driven hub 102 formed on the clutch output gear 86.
  • a clutch drive spring 103 Secured to the hub 102 is one end of a clutch drive spring 103.
  • the other end of the clutch drive spring, indicated at 104, is connected to a release member in the form of a thin cylindrical shell having a blocked surface 106.
  • the spring 103 is presprung so as to tightly engage the hubs 101, l02provided that the release member 105 is free to rotate.
  • the spring 103 is partially unwound so that slippage occurs between the drive hub 101 and the spring with the result that no torque is applied to the driven hub 102.
  • an electromagnet 110 is provided having an armature 111 terminating in a finger 112 which is interposed in the path of movement of the blocked surface 106.
  • the electromagnet When the electromagnet is energized, by means to be described, the release finger 112 is lifted slightly out of blocking relation with respect to the surface 106 which permits the spring 103 to grip the hub 101, with the result that driving torque is applied to the clutch output gear 86. Because of the wrap around effect of the spring on the hub 101, the applied torque winds the spring ever more tightly about the hub so that, once the clutch is released, a large amount of torque may be transmitted.
  • the electromagnet 110 is released almost immediately after it is energized, dropping the finger 112 once again into the path of movement of the blocking surface 106 so that only a single revolution of the output gear 86, and a single revolution of the eccentric gear 88, occurs.
  • means are provided for holding the clutch output gear 86 in a position which slightly expands the clutch spring 103. This is accomplished by a thin retaining arm 115 which is mounted, for adjustment, on a plate 116, and the tip of which engages a stop surface, or dog, 117 formed on the end face of the gear 86.
  • the cutter and its driving arrangement that substantially no load is interposed upon the driving motor at the start of the cut so that the cutting stroke may begin promptly and smoothly.
  • the arrangement between the eccentric and the arm 92 which it engages is such as to provide both maximum torque and maximum speed over the central or cutting portion of the blade cycle. This is accomplished by phasing the members as shown in FIG. 9. Here the cutting portion of the stroke, and direction thereof, is indicated by the curved arrow. It will be apparent that with the members oriented as shown, the angular velocity of the arm 92, and the effective radius of such arm, will both be maximum at the center of the cutting stroke. With both the lever arm and velocity maximum, it follows that the maximum power will be delivered to the knife from the drive mechanism during the cutting stroke.
  • the idler gear 87 is preferably mounted on a shaft which is sufficiently long as to permit endwise sliding into a disengaged position to adjust the phase of the eccentric to that shown.
  • a length setting mechanism 120 is provided which is fingertip-operated for setting a pointer 121 into a position of alignment with the end of the original document 14 and for simultaneously adjusting, with respect to the length dimension of the table, a trigger 122 which triggers a switch S6 mounted upon the frame of the machine.
  • the switch is electrically connected to the electromagnet 110 which controls the single revolution clutch associated with the cutter.
  • the length selecting mechanism occupiesa small subframe 130 mounted on the table having a finger wheel 131, a pinion 132 driven thereby, a gear 133 and pinion 134, the latter being directly coupled to a long pitch helical cam 135 which carries a cam follower or rider 136 of which the leading end 122 constitutes the trigger. It will be apparent that when the finger wheel 131 is rotated by fingertip pressure the gear train is rotated to rotate the helical cam for positioning of the pointer 121 which results in the appropriate and automatic positioning of the trigger 121.
  • the finger wheel 131 is floatingly mounted upon a bell crank 137 which is upwardly biased by a spring 138.
  • the opposite end of the bell crank carries teeth 139 which lockingly engage the teeth of the cam drive pinion 134.
  • the finger wheel 131 is out of engagement with the gear train and the helical cam is positively locked in position.
  • fingertip pressure is downwardly applied against the finger wheel 131 engaging the teeth thereon with the teeth 132 of the pinion and simultaneously retracting the locking teeth 139 so that movement of the finger wheel in one direction or the other can produce corresponding movement of the rider 136 and the pointer and trigger which are mounted upon it.
  • a screw and slot adjustment 140 between the pointer 12] and rider 136 permits precise adjustment of the length of the copy sheet relative to the length of the original document.
  • documents may be copied having a wide range of length. They may be as long as the swept length of the platen on the table, or anything less than this down to a dimension which is slightly longer than the length from the cutter to the drive rollers 35. All that is necessary is to place the original document 14 on the table so that one end thereof coincides with a reference edge 141, following which the finger wheel is pressed and rotated in one direction or the other until the pointer 121 is in its aligned position. With length d3 properly set, relative adjustment of the trigger 122 insures that the length of the copy sheet will precisely match the length of any original document within the range of the machine.
  • the copy sheet is maintained at a precisely constant velocity, synchronized with the movement of the table, from the beginning to the end of the exposure notwithstanding the fact that the trailing edge of the copy sheet is held stationary during the time that it takes the cutter to operate.
  • This difference of motion is accommodated by forming the copy sheet into a free loop between the cutter and the exposing station with provision for taking up the loop during operation of the cutter.
  • the loop is formed by causing the copy sheet to turn through an angle of 180 as shown in FIG. 1.
  • the copy sheet follows the curbed path indicated at 31, riding on internal ribs or the like in the turnaround 32, and which path defines a dimension d1 (see FIG. 1b).
  • the loop 31 which is unobstructed along its inside surface, is temporarily shortened so that it pulls away from the turnaround guide surfaces and follows the shorter path indicated by the dot-dash line 31a. Because of the rapid operation of the cutter, the loop becomes no shorter than that indicated at 31a so that it remains free and so that the velocity of the copy sheet in the exposing station 36 is not, even transiently, afiected. As soon as severance is complete, the trailing edge of the copy sheet is free to spring back to the position 31, and charging and exposure of the trailing portion of the sheet is completed.
  • the overall operation of the machine will become clear upon considering the means for driving the various rollers within the machine, the clutches for driving the table forwardly and backwardly, and the positioning of the switches used for interlocking and control purposes.
  • the rollers 35, 45 and 417 are, first of all, directly coupled to the main drive motor M for rotation at forward table speed.
  • the means employed for reciprocating the table have been shown only diagramatically in FIG. 3 in the form of a forward clutch 151 and reverse clutch 152, which are driven by the main drive motor M and which are selectively energized to power a drive pinion 153 which engages a longitudinal rack 154 on the table.
  • the clutch 155 which is shown in FIG. 1 as interposed between the drive motor and the web drive rollers 22, for rotating the latter at table speed, may be understood to be similar to the clutches 151, 152, or, indeed, may be any clutch of small size capable of clutching a load upon being electrically energized.
  • Switch S4 will be understood to be a home switch which is in the condition shown in FIG. 13 as long as the table is in its home position but which is thrown to its alternate condition (downwardly) whenever the table is away from home.
  • S3 will be understood to be a limit switch which is normally closed but which is opened in the event the table reaches its limit of forward movement.
  • Switch S8 which will normally be mounted upon the control panel, is momentarily closed to initiate a copying cycle and may be considered to be a pushbutton. When the switch is held down copies will be produced continuously. That is, when the table returns to its home position contact is automatically made in switch S4 (upper contact) to recycle the relay K3 to initiate a further stroke of table movement for production of multiple copies as long as the switch S8 is held closed. Or, the switch may be bridged by a switch in a cycle counter to produce a desired number of copies.
  • the switch S8 serves to trigger a relay K3 having a set of sealing-in contacts K3A as well as single pole, double throw contacts K313.
  • a second switch, S7 is connected in series with switch S6 and physically positioned so as to be encountered by the trigger 122 on the table immediately after switch S6 is operated.
  • full wave rectifiers are interposed as shown at 163, 164, 165 for supplying the forward and reverse clutches and for supplying the intermittent drive clutch 155 which controls rotation of the web rollers 22.
  • clutch release magnet is of the AC.
  • switch S2 (see FIG. 1b) which has a probe 170 which has a first obstructing surface 171 which is engaged by the leading edge of the sheet 31 as it enters the exposing station 36 and a second obstruction 172 which is not cleared until the trailing edge of the copy sheet leaves the exposing station.
  • switch S2 is in the condition shown in FIG. 13 as long as there is no sheet in the exposing station but is in its alternate condition as long as any portion of a sheet is in the exposing station.
  • An original document 14 is placed upon the transparent platen of the table adjacent the reference edge 141.
  • the finger wheel 131 of the length selector mechanism is then pressed and rotated until the pointer 121 is aligned with the end of the original document which causes the trigger surface 122 to be properly located with respect to the cutter switch S6.
  • Switch S4 which signals whether the table is in its home position is thrown from its upper position to its lower position as the table moves away from home.
  • the cutter blade is provided with a wedge-shaped filler piece on its front side (FIGS. 4 and 7).
  • the length selector, cutter and remaining portions of the machine and its control circuitry have fulfilled the objects set forth above in the production of a copy, in a minimum length of time, of an original document of any desired length within the capacity of the machine, simply upon adjusting the length selector and pressing the start button. Operation of the machine is silent and free of the annoying thump which usually characterizes machines of the roll-fed type.
  • any type or weight of photocopy paper may be handled with ease, and since the load curve of the cutter is smooth, starting from zero and without any sharp peak, the cutter may be driven by the same motor which normally drives the propelling rollers by the simple expedient of training the roller drive belt about the input pulley 81 of the single revolution clutch. Alternatively, a separate, light duty cutter drive motor may be used.
