- ABSTRACT In a document-handler adapted for feeding, separating and stacking sheets and the like, control means for sensing and counting separated sheets and having a capability of counting, statistically sampling and batching and including means for anticipating jam conditions to protect the counting mechanism, as well as the sheets, from being damaged.
- the sensing mechanism has the capability of self-adjustment to automatically compensate for any and all conditions which affect the sensitivity of the sensing device, and further has a capability of distinguishing between separated documents and apertured or mutilated documents.
- the electronic circuitry controls the mechanical functions to achieve the desired counting, separating, batching and statistical sampling operations.
- the present invention relates to electronic control means and more particularly to novel electronic control means for use with document handling equipment for feeding, separating and stacking documents which electronic equipment monitors all phases of the physical operations to provide reliable and accurate feeding,
- Document handling devices are presently employed in a large number of different applications. Some examples of such document handlers are devices for counting checks, punch cards, food stamps, paper currency and bank coupons, to name just a few.
- the basic requirements of such devices are to provide reliable operation at relatively high operating speeds in the feeding, separating, endorsing and stacking of the documents being handled. For example, during such high speed operations, a separation between documents may be quite small, requiring a sensing device capability of de tecting such small separation distances. Due to the high speed operation, it is also important to provide means for protecting against faulty operation since if a jam were to occur with the documents fed at reasonably high rates of speed, severe damage to the mechanism, as well as the sheets, may occur before corrective measures can be taken.
- sensing means further incorporates means for anticipating a jam condition by automatically halting the document handling apparatus upon failure of the sensing means to sense a gap be tween adjacent documents within a predetermined time period.
- control means which has the further novel capability of increasing the flexibility and effectiveness of the document handling apparatus to perform a variety of document handling operations such as, for example, endorsing, batching and statistical sampling not heretofore capable of being obtained through document-handlers and control devices which have heretofore been available.
- Another object of the present invention is to provide novel electronic control means for document-handlers and the like having capability of distinguishing between adjacent separated documents for counting purposes while ignoring perforations, punches, slits or mutilations within a document as an erroneous indication of a separation between documents.
- Another object of the present invention is to provide novel electronic control means for document-handling apparatus and the like to enhance the capability of such apparatus to perform operations such as reliable high speed counting, batching, statistical sampling and is capable of retaining an existing count and resuming counting even in the event of jams or temproary exhaustion of the supply of documents being counted.

- FIG. Ia shows an elevational view of a statistical sampling mechanism for use with the apparatus of FIG. 1.

- the document-handling device has the major functions of providing means for feeding sheets of varying thicknesses, sizes, finishes and the like and of accepting such dissimilar sheet sizeswithout first collating sheets into groups having similar dimensional and/or surface characteristics and includes means for separating and counting the sheets and stacking the sheets once separated.
- Device 10 of FIGS. 1 and 2 is comprised of a housing 11 having a base portion 12 for supporting device 10 upon any suitable surface such as, for example, a table or counter.
- a suitable surface such as, for example, a table or counter.
- the relatively small size and light weight of the device greatly enhances its portability and facilitates handling of the device to enable its use in practically any desired location.
- the housing 11 is provided with a front face 13 at its upper end which may be fitted or otherwise provided with control panels incorporating controls to be more fully described hereinbelow for turning the machine on Face 13 forms a portion of the front of housing 11 which is. further provided with an infeed hopper l4 consisting of a plate member for stacking sheets or other documents S.
- the stack S has a portion of its weight resting upon rearward end 15a of plate 15 and the sheets have their forward edges resting against a plate 16a.
- the inclination of the infeed stacker 14 is such that the weight of the sheets within the stack serve to retain the sheets within the infeed hopper without providing any jtopweight upon the stack, as well as serving to facilitate feeding of the documents fromthe infeed hopper, which features. are described in detail in the aforementioned application andwill be omitted herein for purposes'of simplicity.
- a picker wheel 19 mounting to rotate about shaft 20 is providedwith an insert or raised portion l9atwhich protrudes through a suitable openingprovided in plate 15a to engage the lowermost sheet within the stack and advance this sheet toward a drive wheel 23 mounted to V t rotate in ,a direction shown by arrow 26 about shaft 24.
- a stripper wheel 52 mounted to rotate upon shaft 47 and being resiliently mounted in a manner described in detail in the aforementioned US. application to perform a stripping operation.
- Wheel 52 rotates in the direction shown by arrow 54 and serves to move documents other than the bottom-most sheet in a rearward direction so as to permit only the document to pass between wheels 23 and 52 toward an acceleration wheel assembly to be more fully described.
- the coefficient of friction of the periphery of wheel 23 is greater than the coefficient of friction of the peripheryof wheel 52 so that when only a single sheet passes between these wheels (as the result of either a stripping operation or the feed of only a single sheet),
- qdrive wheel 23 exerts the major influence upon the sheet causing it to be fed in theforward feed direction toward acceleration wheel 60 mounted to rotate in the direction shown by arrow 62 aboutshaft 61.
- the accel- ,eration wheel 60 cooperates with free-wheeling rollers wheels 60 and 64 and the leading edge of the next document being fed toward wheel 60 by wheels 23 and 52.
- This gap is sensed by means of a light source 65 cooperating with a light-sensitive transistor 72 or other suitable light-sensitive-device which generates a count pulse when the gap is in the region between light source 65 and transistor 72.
- plates 15a and l6a are provided with suitable openings (not shown) to permit the passage of light between devices 65 and 72 when the 'gap" is in this region.
- Sheets advanced by acceleration wheel 60 are kicked into a stacker mechanism comprised of a stacker plate 81 and a kicker wheel 84 mounted to rotate about a shaft 85 in the direction shown by arrow 91 so as to neatly stack counted sheets within the stacker" mechanism.
- the stacking plate 81 is urged in the direction of arrow 97 by suitable bias means described in greater detail in the aforementioned U.S. application. As the number of sheets in the stacker is increased, the sheets urge plate 81 in the direction shown by arrow 98 against the force of the biasing means to firmly retain the sheets within the stacker.
- FIG. 2 shows the driving mechanisms employed for operating the various wheels described hereinabove in connection with FIG. 1.
- the apparatus is provided with a motor M having an output shaft 129 extending through machine frame F to which motor M is securely fastened.
- a pulley 130 is rigidly secured to shaft 129 and drives the acceleration wheel shaft 61 by means of a belt 63 entrained about pulley 130 and a pulley 62 mounted to acceleration wheel shaft 61.
- the opposite end of shaft 61 is provided withpulleys 133 and 134. Pulley 133 is locked to shaft 61 and drives the kicker wheel shaft 85 by a belt 132 which is entrained about pulley 133 and a pulley 89 locked to shaft 85.
- Belt 132 is a resilient O-ring type belt and is looped in a figureeight fashion to rotate shaft 85 in a direction reverse y .and a pulley 136, locked to one end of'drive wheel shaft 24.
- the opposite end of drive wheel shaft 24 has two pulleys 25 and 138 locked to the shaft.
- a belt 142 is entrained about pulley25 and pulley 21, which is locked to the picker wheel shaft 20.
- Belt. 140 is entrained about pulley 138 and idler shaft pulley 42 which is locked to the idler shaft 39.
- Shaft 39 serves to impart rotation to the stripper wheels 52, 52 by means of a belt 45 entrained about pulleys 44 and 38, respectively, locked to shafts 39 and 31.
- a second pulley portion of pulley 38 imparts rotation to a pulley 51 mounted to stripper wheel shaft 47 by means of a belt 50.
- This floating mechanism for the stripper wheels 52, 52 serves to impart rotation to stripper wheels 52, 52 while freely permitting the stripper wheel'assembly 30' to float above the drive wheels 23-23c in a manner which is set forth in detail in theaforementioned US. patent application.
- Pulleys 133 and 89 are provided with semi-circular grooves around their periphery for receiving O-ring type belt 132. All of the remaining pulleys are provided with gear-like outer peripheries for engaging teeth provided on the belts which they engage, which belts are commonly referred to as timing belts. All of the belts have been shown in FIG. 2 in phantom line fashion to facilitate and simplify an understanding of FIG. 2.
- An electromagnetic brake 137 is fastened to machine frame F and selectively engages one end 20a of picker wheel shaft 20. Whenenergized, brake 137 abruptly stops shaft 20 from rotating. When deenergized, brake 137 permits shaft 20 to freely rotate.
- FIG. la which is provided for performing statistical sampling" and/or collating operations and comprises a gate member 201 rigidly secured to shaft 202. At least one end of shaft 202, which extends to one side wall of the machine frame (not shown for purposes of simplicity) is fitted with a lever arm 203 rigidly secured thereto.
- a relay 204 has its armature 204a coupled to arm 203 and, when deenergized, maintains the gate 201 in the solid line position. Energization of the relay causes the gate and arm'to move against the force of a biasing spring (not shown) to the dotted line position 201'.
- relay 204- is energized to move the gate to a solid line position 201, causing the 100th sheet to be moved toward stacker 80.
- relay 204 is energized to cause the next sheet to be fed between belts 207 and 208. This operation is repeated wherein the document-handling device counts the total number of sheets and retains only every 100th sheet in stacker 80, as a statistical simple. The remaining sheets in the depository 215 may be discarded or put to any other desired use.
- any desired statistical sample may be selected by means of an adjustable switch means to be described in greater detail in connection with the electronic control circuitry.
- the counter provided in the electronic control unit to be more fully described hereinbelow has its count advanced for each gap sensed.
- the accumulated count in the counter is compared against the setting of thedesired statistical sample to activate relay 204 so as to accumulate only the statistical samples in stacker 80 while feeding remaining sheets to the depository 215.
- the clutch and brake mechanisms as described hereinabove are selectively activated by an N-] signal and an N+l signal to assure the presence of a gap G of sufficient length between the sheet preceding the Nth sheet and the sheet immediately following the Nth sheet to provide sufficient time for physical movement of gate 201.
- Decoding circuitry within the electronic control means generates an N] signal when the trailing edge of the sheet preceding the Nth" sheet passes sensor 72, causing the drive, stripper and picker wheels to be disengaged from the motor drive and be abruptly halted as a result of actuation of the electromagnetic brake 137 so as to slow down" the Nth document.
- Gate 210 is moved from the dotted line position 201' and the 6 brake and clutch mechanism are then released to continue the feed operation.
- the above operation is repeated in the reverse order to set the gate to the dotted line po- I sition 201.
- the feed operation is again restored until the next statistical sample approaches sensor 72.
- the gate assembly described hereinabove may also be employed for collating.
- every .odd sheet an original
- every even sheet a carbon copy of the original sheet
- This may be done by operating the gate as described above between every sheet fed to the apparatus.
- lt is also possible, for example, to stack original sheets in the stacker and, for example, five carbon copies of each original sheet in the depository 215 for further collating or processing, if desired.
- the document handler in FIGS. 1 and 2 may also be employed for performing batching operations. For example, let it be assumed that a large number of sheets are to be piled into separate stacks with each stack containing an equal predetermined number of sheets. For example, let it be assumed that a large number of dollar bi1ls(paper currency) are to be stacked into stacks each containing one hundred one-dollar bills.
- the paper currency may be stacked in infeed hopper 14 and may contain any number of bills up to the maximum capacity which can be handled by the infeed hopper.
- a start" button is depressed and the mechanism begins to count bills.
- the counter compares its count against the matching count set into the electronic control mechanism to generate a signal after the passage of the 100th bill which energizes electromagnetic brake 137 and deenergizes clutch 131 so as to abruptly halt the picker, stripper and drive wheels while continuously rotating the acceleration and picker wheels to assure positive stacking of the 100th bill within stacker 80.
- the machine then automatically turns off, at which time a stack of exactly one hundred one-dollar bills will be neatly stacked in the stacker 80.
- the operation may then be repeated by depressing the start button to count and stack the next group of 100 one-dollar bills.
- FIG. 3 shows the document detector 300 which is comprised of a light-sensitive transistor 72.
- the emitter is activated when a gap be tween separated documents is detected.
- the collector of transistor 72 is coupled to a dc. source +V while the emitter electrode is coupled through resistor R1 to ground bus 301.
- the emitter is also connected through lead 302 to the base of transistor 303 whose collector is coupled through resistor R2 to the dc. source +V.
- the emitter electrode of 303 is coupled through capacitor C1 to ground bus 301 and through resistor R3 to one input 304b of an operational amplifier 304 which is utilized in circuit 300 as a comparator.
- Resistor R3 is further coupled through resistor R4 to ground bus 301.
- the emitter electrode of light-sensitive transistor 72 is further coupled to the remaining input 304a of operational amplifier 304.
- transistor72 In the quiescent state, i.e., when no gap is sensed, transistor72 is in the non-conductive state so that its emitter electrode will be at ground potential thereby applying a ground potential to the base of transistor 303.
- the emitter of transistor 72 thus applies ground potential to input 304a of comparator 304.
- the ground potential applied to the base electrode of transistor 303 maintains 303 in the non-conductive state.
- Resistors R3 and R4 form a voltage divider whose output point is the common terminal 305 therebetween.
- Resistor R4 has a substantially high resistance value of the order of 100 K Ohms which preferably-is greater than the resistance value of resistor R3
- the threshold level above which a pulse developed by transistor 72 will be detected as a gap and below which threshold level an output pulse will not be detected as a gap will, if the threshold level is maintained constant for long periods of operation, result in the erroneous detection.
- the threshold levelselected is a compromise between the maximum output level of the light-sensitive transistor and an output level of the light-sensitive transistor which will occur as a result of passage of light through documents which, while not being transparent, are nevertheless translucent and will permit some portion of the light from source 65 to be transmitted through the document.
- the threshold level will thus be adjusted accordingly dependent upon the light transmitting characteristics of the documents or sheets to be handled by the device of FIG. 1.
- resistor R will develop a voltage drop of 5 volts across its "terminals representative of the maximum white condition E,,,.
- a +5 volt level at the emitter of transistor 72 is thus applied to the base electrode of transistor 303 causing the transistor to conduct so as to charge'capacitor C at a very rapid rate.
- the +5 volt d.c. level (E is also applied to input terminal 304a of comparator 304 for comparison against the thresholdlevel in a manner to be more fully described.
- Capacitor C1 charges at a rapid rate to develop a voltage E due to its coupling to the emitterof transistor 303 so as to charge to the level of +5 volts do.
- the voltage dividier network comprised of resistors R and R develops a voltage E, at terminal 305 which represents the threshold level against which'the output voltage level E will be compared. In the example given hereinabove, this level will be of the order of 3% volts.
- Operational amplifier 304 functions to generate a positive output level whenever the voltage level at its input 304a exceeds the voltage level at its input 304b.'ln the particular example, E,,, is greater than B, causing a positive level to be developed at output 3040.
- the resistances R and R may be made adjustable so asto adjustably select the threshold level E,.
- a sheet having some light transmissive properties passes between light source and light-sensitive transistor 72 (see sheet S in FIG. 3). Some light will pass through sheet S causing transistor 72 to partially conduct whereby the output level at its emitter electrode will be a level equal to or less than the E, level established during the previous gap. This level will be sufficient to drive transistor 303 into conduction to charge capacitor C and develop a threshold level which preferably should be greater than the level at the emitter of 72 to cause comparator 304 to be prevented from developing a positive level.
- the threshold level E must be sufficiently greater than the lever E so as to prohibit light passing through a light transmissive, or partially light-transmissive (i.e., translucent) document from being erroneously detected as a gap between the two documents.
- the self-compensating feature of the circuit is obtained as follows:
- resistor R and R have resistive values which collectively are relatively high so that the sums of these resistances are of the order of greater than 100,000 Ohms to provide a relatively long time constant for the discharge of capacitor C as will be more fully described hereinbelow.
- the sheets being handled by the document handler 10 of FlGS. l and 2 are preferably moved at a rate of the order of 60 inches per second. Assuming the length of a document measured in the feed direction to be of the order of 3", the movement of the document in passing between light source 65 and light sensitive transistor 72 will be of the order of 50 milliseconds. Considering FlG. So, let it be assumed that at time t the leading edge of a document S moves between light source 65 and light sensitive transistor72. At this time the voltage output at the emitter electrode of transistor 72 will be at 5,, (assuming that the document is partially light transmissive as opposed to opaque) and willallow some light to pass thereth'rough.
- the output at the emitter electrode of transistor 72 will be at the level E,, which level is applied to input 304a of comparator 304. Due to the low discharge rate of capacitor C, (to be more fully described) the level at terminal 305 of the voltage divider network will be at E, which level is applied to input 304b of comparator 304, thus causing the output 3040 of comparator 304 to assume ground level.
- the level E is retained at the emitter electrode of transistor 72 until the leading edge of sheet S" moves into the region between light source 65 and transistor 72 at time T causing the conductive state of transistor 72 to be significantly reduced thereby dropping to the level E,, and causing C, to discharge very slightly.
- This level will be sustained until time t, when the trailing edge of document S"-leaves the region between light source 65 and transistor 72 and before the leading edge of the next document (not shown for purposes of simplicity) enters into the aforesaid region.
- capacitor C discharges at a rate such that the voltage across its terminalsis close to 90 percent of the voltage E,.
- waveform 306 of FIG. 5b shows a series of pulses which occur over a substantial elapsed time which may be of the order of days or weeks.
- FIG. 5c shows a portion of waveforms 306 and 307 in greatly enlarged fashion to more clearly explain the operation of capacitor C, and the voltage divider network comprised of resistors R and R Let it be as sumed that the document feeder is turned on.
- light source 65 causes the capacitor C, to charge rapidly as shown by portion 306a of waveform 306.
- the first document passes through the region between lamp 65 and transistor 72 causing the output level. of the emitter electrode of transistor 72 to drop to the voltage level B
- capacitor C will discharge at a slow rate as shown by the waveform portion 306b where capacitor C, will drop to a voltage level of the order of percent of its maximum voltage E,.
- the trailing edge of the document will move out of the region between lamp 65 and transistor 72 causing the output level of transistor 72 to go to E,,,.
- capacitor C will charge to its full value in a very brief time period as shown by the portion 306b of waveform 306.
- Capacitor C will become fully charged and remain at the level E, until time t at which time the leading edge of the next document moves into the region between elements 65 and 72 causing the output level at the emitter electrode of transistor 72 to drop to the level E,,,.
- the capacitor will again discharge at a very slow rate as is represented by the portion 306d of waveform 306. This operation is .continuously repeated in the same manner as was described hereinabove for each additional gap sensed between the documents being handled by the device 10.
- the output level E will gradually be reduced as was described hereinabove causing capacitor C, to charge to a lower voltage level due to the reduced voltage applied to the base electrode of transistor 303.
- the threshold level E will continue to be gradually reduced, but will remain at a level which remains proportional to the maximum output level E,,,,, E,,,,, E and so forth, as the sensitivity of transistor 72 is gradually reduced. It can thus be seen that the detector of FIG. 3 fully compensates for any gradual changes in the sensitivity of the detector.
- Comparator 304 is designed so as to develop an output level of zero volts during the time when the document is passing in the region between elements 65 and 72 and is adapted to develop a positive output level of the order of +5 volts during the time that a gap is detected.
- the elapsed time t t represents the time between which the leading edge of a document enters into the region between elements 65 and 72 and the time at which the trailing edge of the documents leave the aforesaid region.
- the circuit 310 which prevents such narrow impulses from being erroneously. interpreted as a gap between documents is shown in FIG. 4a and is comprised of an input terminal 311 coupled to the output 304c of comparator 304 for receiving count pulses.
- Series connected capacitor C andresistor R are coupled in series between +5 volts d.c. and ground with their common terminal 312 coupled to input line 311 which is coupled to the output of comparator 304.
- C and R provide filtering against high frequency noise such as that generated by motors, etc. which may be magnetically coupled into line 311.
- Input line 311 is coupled to one input of NAND gate 313.
- the operation of NAND gate 313 is such as to develop a high voltage level when any one or more of its inputs are low and to develop a low level when all of its inputs are ata high level.
- the output of NAND gate 313 is coupled to one input of inverter 314 whose out put is'simultaneously coupled to one input of NAND gate 315 and one input of NOR gate 316.
- NOR gates as a voltage divider coupling a portion of the output 316 and 317 are cross-coupled to form a single shot filter circuit (SS-Filter) which operates in a manner to be fully described.
- the output of NOR gate 316 is coupled to one input of NOR gate 317 while the output or NOR gate 317 is coupled to the remaining input of NOR gate 316.
- the output of NOR gate 316 is further coupled to one input of NAND gates 315 and 318 and to the input 319a of a one-shot multivibrator 319.
- the remaining input of NOR gate 317 is coupled to one terminal of capacitor C whose opposite terminal is coupled to ground.
- Parallel connected diode CR and resistor R are coupled in parallel between the output of NAND gate 315 and capacitor C
- the output of NAND gate 318 is simultaneously coupled to the dc. supply terminal V through resistor R, and through resistor R to the jam-delay and jam-prevention delay circuits 320 and 330, to be more fully described.
- the jam-delay circuit 320 is comprised of diode CR and capacitor C for developing a rectified and filtered d.c. level at their common terminal.
- a potential divider comprised of resistors R and R applies a portion of this voltage to the base of transistor 0 whose collector is connected to the dc. +V through resistor R and whose emitter is connected to ground.
- the collector is coupled to the input of inverter 32! whose output is coupled to the remaining input of NAND gate 313.
- the jam prevention delay circuit 330 is'similar in design to the jam delay circuit 320 and is comprised of diode CR and capacitor C: for rectifying and filtering the input applied thereto.
- Resistors R and R operate voltage appearing at the commonv terminal between diode CR and capacitor C to the base electrode of transistor Q whose emitter is connected to ground and whose collector is coupled to +V through resistor R During the time when no counting is being performed a portion of the dc. level is applied to the emitter of transistor Q causing Q, to conduct. At this time the collector of Q, will be low (substantially zero volts) causing the output of inverter 32] to go high, thereby placing a high level at one input of NAND gate 313.
- NAND Gate 315 goes high causing capacitor C3 to charge rapidly to the high level through diode CR1 and causing the output of NOR gate 317 to' go low. This low level is applied to the remaining input of NOR gate 316 causing its output to remain high.
- This high level signal is applied to input 319a of one shot multivibrator 319 to cause an output pulse of a predetermined pulse width to be developed at output terminal 31%. Simultaneously therewith, a positive going pulse is developed at the remaining output 3190 of one-shot multivibrator 319 which is applied to a circuit comprised of transistors Q Q and Zener diode CR for developing an output at the collector electrode of Q employed to advance an electromagnetic counter means (FIG. 4c) by one count.
- the output of comparator 304 remains at the low level for the duration of the passage of a document which is of the order of 50 milliseconds, after which time the level at lead 311 abruptly increases to +5 volts d.c., causing the output of gate 313 to go low and the output of inverter 314 to go high returning a high level to gates 316 and 315.
- the output of gate 315 thus goes low.
- capacitor C and the resistance value of resistor R are chosen to cause capacitor C to discharge at a slow rate whereby the high level at the terminal of capacitor C coupled to one input of NOR gate 317 is retained thus preventing the bistable circuit comprised of NOR gates 316 and 317 changing state and thereby preventing an erroneous pulse from being applied to one-shot multivibrator 319 until capacitor C; has had sufficient time to discharge.
- the discharge rate of capacitor C is appropriately adjusted so as to permit the capacitor to fully 13 discharge during a- 20 millisecond time duration which lies-well within the normal time interval of a gap but is adjusted to preventthe capacitor from being discharged within 1 shorter time intervals which would occur as a result of holes, tears, or other mutilations in the document passing between lamp 65 and detector (transistor 72).
- gate 318 When the output of NOR gate 316 goes high, gate 318 is caused to develop a low level output to permit capacitor C in the jam-delay circuit 320 to begin discharging.
- the time interval during which capacitor C, will be fully discharged is of the order of 100 milliseconds which is greater than the time required for the passage of one sheet through the region between lamp 65 and transistor 72 so'as to maintain a high level output at the remaining input of gate 318.
- the objective of these circuits is to distinguish between a gap between the trailing edge of a document and the leading edge of the next document, as they pass the sensor 72, and the presence of holes or tears within the body of a document, so that such holes will not be erroneously interpreted as a gap so that to prevent an erroneous count pulse from being generated.
- This problem is extremely important in the counting of documents which have punched codes provided therein.
- the interval of elapsed time typically required for C to discharge from a full charge (approximately 5 V.d.c.) to thereset threshold level (approximately 0.8 V.d.c.) is of the order of milliseconds. In this time interval assuming a rate of movement of documents as 60 inches per second, the trailing edge of the last document will have travelled a distance of the order of 0.60 inches.
- the leading edge of the next succeeding document will not have arrived at sensor 72. Since the reset level has been reached by the discharge of C and the output 317a has gone high, the output of gate 315 goes high causing C to begin charging before the leading edge of the next document is detected by sensor 72. Once the leading edge is detected the output of 304 goes low causing the output of 313 to go high and the output of 314 and the input 31612 of 316 to go low whereby the output 316a of 316 goes high, which is applied to one input of 317 and 315.
- Mutilations or holes of types other than punched holes and are of the order of 0.50 inches or less in the direction of movement can thus be prevented from being interpreted as a gap".
- the minimum length of a gap is dictated by the minimum response of the circuitry and should preferably be of the order of 0.40 inches.
- Jam-prevention delay circuit 330 operates in a similar fashion such that its one input terminal is coupled to +5 volts while its remaining input terminal is coupled to the output of NOR gate 136.
- the remaining input of NAND gate 318 goes high causing its output to go now enabling capacitor C to begin discharging. If the output of NAND gate 318 does not go high during a time slightly greater in-time duration than the time in which the document should be present, capacitor C will discharge causing the output of transistor O to go high. This condition is inverted by inverter 323 and applied to one input of NOR gate 324 whose other input is derived from gate 354 of FIG.

- the mechanical arrangement for the thumbwheels' and number wheels have been omitted for purposes of simplicity.
- the mechanical thumbwheel switches selectively couple a high voltage level to each of the input leads, for example, leads 344a344d of the units thumbwheel switch, which couple the high level voltages to associated inputs of the units counter and comparator 341.
- thumbwheel switches provide outputs in nines complement form which significantly simplifies the electrical connections required in. the electronic counter as will be more fully described.
- nines complement is set forth in the text Programming Business Computers published by John Wiley & Sons, 3rd printing, Apr. 1962, on pages 449 and 450.
- a binary coded decimal 9 is, in the nines complement form, a decimal 9 which isinterpreted as a binary coded decimal zero.
- the binary coded decimal form of decimal 9 is 1001 where the weighting of the binary digits from left to right is 8, 4, 2 and 1

- decimal eight and decimal one outputs are terminals 341b and 3410, respectively, and hence the hundreds outputs are similarly labeled as 342k and 3420 and 343b and 343C respectively.
- each counter stage in binary coded decimal nines complement form is 1001, which is the equivalent of 'a' 0000 reading in straight binary coded decimal form.
- the straight binary coded decimal (BCD) form would require a connection of all four tions are required from each stage to sense the nines complement decimal 9 condition.
- the outputs 342b and 342d in tens stage 342 and the outputs 343b and 343d in hundreds output stage 343 are all coupled to associated inputs of AND gate 349 which provides an output when the binary coded decimal nines complement output of each of the stages 342 and 343 are simultaneously in the form 1001

- AND gate 356 has its output go low when the units counter stage 341 is in decimal 9and when the tens and hundreds stages are also in the decimal 9 state causing its output to go low thereby applying a low level to NOR gate 366 whose other input is coupled to the output 321a of inverter 321 (see FIG. 4a) which is high so long as jam delay circuit 320 is not timed out.
- the output of gate 366 goes high and is inverted by inverter 367 to apply a low level output to lead 368 which is coupled to stationary contact 3646' of switch 364.

- Gate 370 and inverter 372 have their inputs coupled to the output 321a (see FIG. 4a).
- the output of inverter 372 is coupled to the base electrode of transistor Q and normally maintains transistor Q nonconductive until the jam delay circuit 320 times out, at which time the output of inverter 321 goes low causing the output of. inverter 372 to go high and render transistor Q conductive.

- gate 370 The remaining input of gate 370 is coupled to the output 376a of NOR gate 376 which is low when the Start button of the control unit is depressed.

- This negative going signal is applied to the input of single shot 397 producing a negative pulse.
- the output of gate 356 is simultaneously coupled to one input of OR gate 366 and inverter 394.
- the output of OR gate 366 is coupled to inverter 367, whose output is coupled to batch switch 364 and via lead 369 (when the batch switch 364 is in its upper position) to one input of NOR gate 376 resulting in a high condition to AND gate 370 thereby rendering transistor 0.. to be conductive so as to illuminate a lamp 389 indicating the completion of a batch.

- NOR gates 375 and 377 are both high when the counter is running and the start button has been depressed and subsequently released causing the output of AND gate 379 to go low, which condition is applied to NOR gate 381 causing its output to go high rendering transistor 0, conductive.
- This condition causes solenoid coil K, to be energized thereby causing switch arm 402a of switch 402 to engage stationary contact 402b.
- Switch arm 402a is magnetically coupled to solenoid K, as designated by dashed line 403.

Gate 407 is low to keep relay Ki energized so long as there is no jam condition (311a FIG. 4a) and a document is passing the sensor.-
- Gate 381 also energizes relay K either when the START button is depressed, or the RUN FF is ON or whenthe STOP FF is OFF (i.e., reset).

- the RUN FF in the reset state keeps motor M off (through gates 379 and 381 and Q,-FIG. 4e); brake 137 energized. (throughgate 380 and 0,,- FIG. 4e); and clutch 131 deenergized (through inverter 381 and O -FIG. 4e).
- start switch 385 In the normal mode, start switch 385 is pressed and released causing switch arm 385b to engage its stationary contact 385a thereby applying a low level to one input of NOR gate 373 shown in FIG. 4e. This will cause the output of NOR gate 375 to gohigh causing bistable flip-flop (RUN FF) comprised of NOR gates 375 and 376 to be set to its run state.
- RUN FF bistable flip-flop
- STOP FF (FIG. 4e) is also simultaneously reset by operation of the start button 385.”
- Start switch 385 also simultaneously releases the Jam Delay Circuit 320 through gate 318 (FIG. 4a), and inhibits the motor drive through gates 379, 381 and 0-, (FIG. 4e).
- RUN FF being set, energizes clutch 131 and deenergizes brake 137 via gate 380, inverter 382 and Q -Q and O -Q
- the second input of AND gate 397 goes high.
- the output of NOR gate 377 is high (see FIG. 4e) causing the three to, go low. This causes.
- NOR gate 381 to go high which initiates conduction of transistor Q
- This energizes relay coil K, to couple the ac. supply through switch 402 (which is now closed) to motor M to allow it to run.
- the light sensitive transistor 72 is energized to develop a count as was previously described.
- the count pulses appear at the output 3190 of one-shot multivibrator 319 shown in FIG. 4a with the circuitry of FIGS. 3 and 4a described hereinabove performing the function of automatically adjusting the desired threshold level and preventing cuts, slits, punch holes or other perforations in a document from being erroneously detected as a gap.
- a document passes sensor 72 the light level is reduced resulting in a low level output from the detector (FIG.3) whose output is applied to C (FIG. 4a) which provides filtering against motor generated noise in the signal and then passes through gate 313 and inverter 314 toset the integrating single shot ISS Filter (FIG. 4a) which serves to prevent holes or mutilations in documents from falsely appearing as gaps.
- the integrating single shot output is applied to one-shot multivibrator 319 whose output 319C is applied to 0 -0 which serve as v 21 a level translator and current amplifier for driving electromagnetic counter 426 (FIG. 4c).
- Jam Delay Circuit 320 and Jam Prevention delay Circuit 330 are prevented from being timed out so long as the time interval between the detection of gaps does not exceed the adjusted time outs for these circuits.
- time out of the Jam Delay Circuit 320 the output of inverter 321 goes low which condition is coupled to lead 430 to FIG. 4c.
- switch arm 364 is coupled to lower stationary contact 364a which couples this condition to lead 369 to input 376a of NOR gate 376 of FIG. 4e to set the bistable flip-flop comprised of NOR gates 375 and 376 to the off state causing the output of NOR gate 375 to go low which causes the output of AND gate 379 to go high.
- Inverter 321 and gate 313 (FIG. 4a), together with gates 314, 317 and 318 form a latch which maintains the jam level as the documents are being removed and also prevent the document detector from producing spurious count pulses as it adjusts to the lower (shadowed) light level.
- the counting process will continue as long as documents are supplied to the input hopper 14 (FIG. 1).
- the document-handling device may be stopped for any reason by depressing stop switch 387 which couples ground potential through movable contact 387b and stationary contact 387a to one input of NOR gate 378.
- This causes its output to go high setting the output of NOR gate 377 low which causes the output of NAND gate 379 to go high thereby setting the STOP-FF.
- This condition together with a high condition at the output of AND gate 407 (see FIG. 4d) causes the output of NOR gate 381 to go low to decouple the a.c. supply from motor M.
- NOR gate 377 The output of NOR gate 377 is further coupled to NOR gate 380 causing its output to go high and thereby energizing the brake and deenergizing the clutch. This prevents documents being engaged by either the picker wheel, drive wheel or stripper wheel assemblies from any further movement into the document-handling device.
- the brake is simultaneously energized to abruptly halt the picker, drive and stripper wheels. Depressing either the CONTINUE key of the stop key will cause the STOP FF (FIG. 4e) to be reset.
- the statistical sampling operation is performed in the following manner:
- Switch arm 412b (FIG. 4c) is placed in the discard" position, switch arm 362b is placed in the stat position and switch arm 352C is placed in the batch/stat" position.
- the thumbwheels are manipulated so that their number wheels show the size of the batch desired.
- FIG. 40 shows the setting where each batch is to contain 50 sheets.
- the start button is depressed.
- the number in the thumb wheel switches is set into the electronic counter 340 as a result of the ground condition from the depression of start switch 385 being coupled through NOR gate 373 (whose output goes high) to develop a low level at the output of inverter 374 causing inputs MIC-343cof counter stages 341-343 respectively, to
- the sampled sheet is slowed up by actuation of the clutch and braking mechanisms which occurs when the units stage of the electronic counter reaches a count of decimal 8.
- This condition is coupled through gate 354 (FIG. 4d), gates 324 and 325 (FIG. 4a) and gate 380 (FIG. 4e) to actuate the brake and clutch mechanisms 137 and 131, respectively, to slow down the statistically sampled sheet to provide the gate sufficient time to move.
- This pulse is developed at the leading edge of the document preceding the statistical sample (i.e. the 49th document), and is active for the full duration of time that document is between the light source and sensor 72.
- gate 354 After the passage of the trailing edge of the document preceding the statistical sample (i.e. the 49th document) the output of gate 354 goes high to actuate the clutch and brake mechanisms. Upon the occurrence of the gap between the trailing edge of the 49th document and the leading edge of the 50th document, the gate is set. As soon as this pulse is terminated and before the electronic counter is advanced by one count, gate 355 (FIG. 4d) sets the gate flip-flop (gates 357 and 358) to energize solenoid coil K (see FIG. 4f) and set it to its solid state position shown in FIG. lb. After counting the gap between the trailing edge of the statistically sampled document, the output of gate 356 goes low causing gate 393 to be enabled (see FIG.
