Abstract

A document feeder comprises an input hopper (1) into which batches of documents with interleaved separators (24, 25) are loaded in use, each separator carrying data related to the associated batch. A feed system (9, 10) withdraws documents and separators singly from the input hopper. A sensing system (7) obtains information about the documents and separators. The sensing system includes a data sensor (7) located so as to read separator data while the separator (24, 25) is in the input hopper (1).

Description

Document feeder and method thereof

Technical field

The present invention relates to document feeder and the method for document is provided, for example banknote etc. has the valency document.

Background technology

Usually need the batch processing document, particularly the valency document is arranged such as banknote etc.These documents are placed in the input funnel of classification or counting machine, and are not usually supplied with continuously by machine with shutting down.

Under this situation, use of beginning and the end of spacer document usually with mark batch.Batch spacer that begins to locate is called as head.The spacer of batch end is called as afterbody.Spacer is except supplying with by machine as common banknote when detected, and reading/detecting after the information that comprises on it, they be drawn towards generally that rejection/suspicious banknote is drawn towards target.This make from be identified batch in rejected or suspicious banknote can be included between head and the afterbody or the head of sign and being used between follow-up check/inspection head subsequently.In single deck tape-recorder film magazine page or leaf sheet counting machine, head or afterbody are sent to the single deck tape-recorder film magazine, when card box is removed by the operator, provide spacer with box lunch page or leaf sheet between processed batch.Thereby, importantly to pick out, when spacer document during supply equipment, guarantee the banknote rejected from each batch quilt and they from batch together identified.Indicate processed batch for the purpose that writes down, and, monitor that spacer also is important for the information about the content of this batch can be provided.

And then must use number mark batch on the head.The bar code that use is printed on the spacer can be accomplished this point.Bar code need be read by segregator.This reading must be reliable and accurate.

As shown in US-A4248528 and US-A-4629311, a batch spacer bar code reader is arranged in the feeder transmission has certain distance with the input funnel traditionally.Reader is a kind of form of static laser, laser scanning bar code when spacer moves through laser beam.

Since batch spacer may be accidental with another can hinder spacer identification document supply with, thereby usually spacer is added further characteristic.This specific character is got the form of the fringe that overflows (proud) (ear) of expression spacer/banknote.Further optical pickocff can be discerned the pattern on the fringe.

Spike sensor is installed in the transmission of feeder, but as far as possible near the input funnel, makes spacer to be identified fully apace, so that can make machine stop to supply with before Next document is supplied to.This is necessary in the machine of some pattern that requires machine to stop when each banknote batch finishes.

This known method has some defectives.For example, need two sensors to detect fringe and bar code respectively.In addition, existing design needs the space to use for the spacer detector between page or leaf chip supplying device and spacer object card film magazine.

Summary of the invention

According to first mode of the present invention, from the method for document is provided at the document heap of storage location, spacer is arranged between in succession document batch, each spacer carries the data relevant with relevant batch, and this method comprises separately provides document and spacer from storage location; And comprise the information of acquisition about document and spacer; It is characterized in that when spacer still is in storage location, just reading the data of each spacer.

According to second mode of the present invention, a kind of document feeder comprises storage location, in use loads the document batch that has staggered spacer to this storage location, and each spacer carries the data relevant with relevant batch; Be used for extracting separately the feed system of document and spacer from storage location; And be used to obtain checking system about document and spacer information, and it is characterized in that checking system comprises a data sensor, its in place making just can be read the spacer data when spacer is in storage location.

The present invention just reads spacer number such as input during funnel by still be in storage location at spacer, according to having solved above-mentioned problem.Spacer or static perhaps with its relative slow speed motion of remainder by transmitting, makes it possible to read data more accurately than traditional method described in above-mentioned two US patent specifications.In addition, needn't provide the special spacer that has fringe.

Document can be supplied with from the bottom of storage location, and when reading the spacer data by adjacent mounted panel, the spacer data read below storage location or from vertically or at angle holding of storage location.Comparable structure can be provided, and wherein the page or leaf sheet is supplied with from the top of processed page or leaf sheet heap.This provides the mode of being convenient to read mask data.

In preferred example, read the spacer data once more than.This has overcome the problem of misreading, and has been in the problem of handling spacer in the transmission at spacer.Like this, before supplying to machine, spacer promptly knows spacer data or sign.

The spacer data are preferably in more than one horizontal position and read.This helps to overcome the problem of data damage or bad printing, particularly in the form of bar code.

In some example, when supplying with, reads storage location the spacer data at spacer.This has removed from needs scan-data.In general, use two parts bar code under this situation, the part of sign indicating number comprises the bar code pattern of definition spacer data, and another part comprises regularly pattern.Can correctly read bar code no matter how this permission speed changes.This method is when not needing to scan the advantage that reads static document, can install cheap read head, and reading is small and exquisite first watch.In any case, owing to the use of above-mentioned reason static document is better.

Though described the present invention with regard to spacer, the present invention can be suitable for more widely.

So according to Third Way of the present invention, document provides equipment to comprise to be used for the feed system of supplying with document from storage location; And detector, being used to detect one or more features of document, this feed system is characterised in that for supplying with document according to the feature that detects detector comprises a sensor of such configuration, makes the feature that can detect document when document is in storage location.

According to cubic formula of the present invention, provide a kind of method of document to comprise from document heap at storage location, when being in storage location, document detects one or more features of the document that is supplied to; And to provide document according to the determined mode of feature (many) that detects.

By when document still is in storage location, detecting file characteristics, can overcome difficulty in document detected characteristics during often with very high-speed motion.In addition, also reduced because transmit the variation of medium velocity cause banknote deflection and irregular scanning the problem of operations detector extremely.

The present invention is applicable to various widely different document supply application, comprises the assortment of bank note device, counting machine and receptor.When the reading bundle that passes through data by scanning read the spacer data, it also was applicable to their long limit or minor face the document of supplying with when leading, can be in any direction with respect to direction of the supply direction of scanning.

The specific embodiment

Document classifier shown in Figure 1 comprises that the part 4 of the height friction of input funnel 1, one elbow (nugder) wheel 5 with pedestal 2 of with holes 3 can stretch out by this hole.Pedestal 2 has second hole of aiming at bar code reader 7 as detailed below 6.Banknote is supported on the pedestal 2 in the heap relative with antetheca 26, and supplies with off and on to height friction donor rollers 9 and the roll gap 8 that spacer, counting machine rotate between the roller 10 by the rotation of elbow roller 5.Document enters pattern detection district 13 by tooled joint roller 11,12, and wherein sensor 14 detects banknote and information is sent back microprocessor 15 when banknote is supplied to, whole operations of this microprocessor control machine.Each banknote supplies to driving belt 18 by tooled joint roller 16,17 then, and this belt sends banknote to diverter 20 around each roller 19.The operation of diverter is by microprocessor 15 control, makes banknote or be directed to output card film magazine 21 to use the stacked 22 stacked banknotes of taking turns of rotation at this as common mode, perhaps is directed to and rejects case 23.

Under this situation, use the head spacer 24 (Fig. 2) under each batch, and the afterbody spacer 25 on each batch, on another, be stacked to input funnel 1 from one of the banknote in the source that separates.So as shown in Figure 2, adjacent one another are between each batch will have an afterbody and head.Among Fig. 2 in order to know that elbow roller 5 has been omitted.

As seen, banknote is stacked on the pedestal 2 and is forced to forward wall 26 in Fig. 2.Be provided with a little gap 27 at antetheca pedestal place, can be pushed by each banknote of this gap and spacer.

Minimum page or leaf sheet is scanned bar code reader 7 scannings in the input funnel 1, and when document was still in the input funnel, this reader moved laser beam by hole 6 and crosses over the document visible part.When or afterbody spacer 25 or head spacer 24 when being minimum document, at this moment to allow bar codes are appreciiables for reader 7 in hole 6.In general, laser beam pass through bar code scanning once more than so that it can accurately be read, and this information offers microprocessor 15.

One example of bar code shown in Fig. 3, and in this case, can see that scanning laser beam passes through bar code scanning with five transverse scan 31-35.The advantage of making is like this, and some bar codes partly damage, then the part of for a moment passing through non-damage that scans at least.

In general, bar code can be printed on the two sides of spacer, no matter make spacer does not all have influence how to be placed into output hopper around mode.Because document is generally with 800 documents of per minute or more supplies, thereby scanning is still carried out fast.

As long as bar code reader 7 has identified bar code, it just sends to bar code identification microprocessor or machine controller 15, and depend on selected procedural type, controller can make feeder stop before spacer is supplied to, to allow previous batch to take out from output card film magazine 21, perhaps it can allow spacer to be supplied to and to handle next batch.

Though might may together supply with its previous banknote by the afterbody spacer, cause that like this afterbody bar code misses reader, the afterbody that will point out machine to miss as the existence of the additional head spacer of next document.

Also can use static state (non-moving) illumination equipment and ccd array scanning bar code, so that read code.Such reader is the representative type reader that the retail outlet is used, and scanning is by the code on the article of scanner.

In a kind of method of modification, the scanning bar code reader is replaced by non-sweeping scheme, and uses the supply of spacer document itself to move realization scanning.Under this situation, must on segregate document, not only provide bar code 40 (Fig. 4) but also provide regularly pattern 41, no matter make how the speed of bar code document changes and can both correctly be read.

In case minimum document is pushed by gap 27, it just picks up and supplies to test section 13 by donor rollers 9.One or more of the sign of test section 13 definite documents or authenticity.Document is fed into diverter 20 then, and this diverter so that according to the information from test section 13 document is supplied to stacked card box 21, or is rejected case 23 by microprocessor 15 controls.In general, identified or the document discerned supplies to output card film magazine 21, and document of rejecting and spacer supply to and reject case 23.

Fig. 5 illustrates and has single second example that the counting machine of container is shown.Counting machine 104 comprises document supply funnel 102, and this funnel comprises by common bolt upper and lower part 101a and 101b together.Being included in the housing 101 is inner chassis assembly (for clear and not shown), and itself has side component, the page or leaf sheet that will illustrate here is housed between the side component supplies with and transmission parts.Two common supply roll 105 non-rotating being installed on the axle 107, this rotation is installed to chassis assembly, and has radially outward outstanding projection 106, and this projection is stretched out by the opening in the pedestal of funnel 102 when supply roll rotates periodically.

A pair of peeling off taken turns 115 non-rotating being installed on the axle drive shaft 116, and this axle drive shaft rotation is installed in the chassis assembly.Each is peeled off wheel 115 and has rubber bush 117 at its periphery surface.Axle 116 is driven by cw by belt 134 by electrical motor 133, so that the bottom of the banknote stack (not shown) from be placed on funnel 102 is supplied with banknote one by one.

Pressure roll 130 is driven with the external peripheral surface lateral alignment of peeling off wheel 115 and from it, and this pressure roll rotation is installed on the axle 131, to peeling off the pressurization of wheel 115 springs.The downstream of wheel 115 is a pair of non-rotating transfer rollers 119 that are installed on the axle 120, and this rotation is installed in the chassis assembly.Axle 120 is driven by cw by belt 136 from second electrical motor 135 as shown in Figure 5, so as with pressure roll to 121 and dual detector roller 123 cooperates, in transfer structure to the stacked 127 transmission banknotes of taking turns that are installed on the axle 128.Rotation is installed in the pressure roll 121 of spring bias voltage on the axle 122 of transfer roller 119, drive with roller 119 lateral alignment and by the periphery surface of roller 119, rotation simultaneously is installed in the non-rotating dual detector roller 123 that is installed to the axle 124 of chassis assembly, though also align, be to cause rotation basically by the banknote that between roller 119 and 123 adjacent periphery surfaces, passes through with transfer roller 119.

Axle 131 and 122 is installed in the top molded assembly 132, and this assembly is from the chassis assembly hinge and form its part.

Between pressure roll 130 and backer roll 121 is that the spacer roller is to 125, this roller is non-rotating to be installed in scalable and to be fixed on the axle 126 on the top molded assembly 132, have outer round surface, nominally its with peel off wheel 115 outer round surface and align, but laterally separate with it.

And the formation part of top molded assembly 132, be partly around the curved guide surface 108 of roller 115,119 circumferential extensions, go up when lifting it and allow the operator near the banknote feeder with transmit passage when the top is molded, so that can remove the banknote of clamping.Surface 137 provides the banknote guiding from the end of curved spigot surface 108 to common stacked device wheel 127.

Driving motor 133 (simply illustrating among Fig. 5) drives axle drive shaft 116 continuously by driving belt 134, and by belt and pulley structure from axle 116, auxiliary drive shaft 107 turns supply roll 105.For clear, the connection between driving motor belt 134 and the axle drive shaft 107,116 is omitted.The axle drive shaft 120 that turns transfer roller 119 is driven by belt drive 136 by driving motor 135.Other pulley and belt composition (not shown) between the non-rotating axle 120 that stacked device wheel 127 is installed and spools 128 on it provide from 135 pairs of driving motors are stacked and have taken turns 127 driving.

Guide plate 109 as the pedestal of funnel 102 continuously, to the roll gap extension that between transfer roller 119 and dual detector roller 122, forms.

Owing to itself be self-explantory, do not explain for the control system of example shown in Fig. 5.

In example formerly, the pedestal of supplying with funnel 102 has a hole 140, one bar code wands 7 to be positioned at thereafter.The mode of bar code reader that is connected to the microprocessor (not shown) in its operation and first example is identical, thereby no longer explanation.

The 3rd example shown in Figure 6 comprises page sheet input table or funnel 202, is tied by the page or leaf sheet that the machine operation person is placed in the input table so that keep.Funnel 202 comprises pedestal 220, places the page or leaf sheet that uses on it.Has a hole 221 of aliging with the same pedestal 220 of previous example with bar code reader 7.Bar code reader 7 will be connected to the microprocessor (not shown) again, and operate in the mode that is similar to previous its example.When 222 rotations of friction donor rollers, a page or leaf sheet minimum in piling on the pedestal 220 is supplied with forward.Under this situation, be the opposite of leading supply with page or leaf length of a film limit in previous two examples, the page or leaf sheet is leading supply with their minor face.Be supplied to from every next of page or leaf sheet bundle by 222 pages of sheets of roller and enter a page sheet transfer system 204, so that transmit each page sheet to one of several stacked card boxes or output table 206,207,208 by detection zone 205.The page or leaf sheet is drawn towards card box 206,207 respectively by flow dividing structure 215,216, this flow dividing structure is by machine processor or the controller (not shown) process control instruction manipulation according to its programming, and these instructions use the feature of at least one detection of each page sheet to determine the target of this page sheet.Do not supplied to card box 208 by the page or leaf sheet of flow dividing structure 215,216 shuntings.In general, card box 208 is used as and selects card box.The design of input table 202, the bundle that increases for the page or leaf sheet of handling in the time of can making page sheet be moved to transfer system 204 is added on the platform.

Each is relevant for each indicating device 211,212,213 and stacked card box 206,207,208, indicating device is an indicating device that can listen or visual in these examples, but can be that any known prompting operation person of can be used to removes the device that the page or leaf sheet is piled from the associated card film magazine, they also can instruct by the instruction manipulation that is provided by machine processor according to the processing controls of programming.

Other indicating device comprises the use of stacked card box, when determining to pile up case and expired, this card box shifts out so that the operator can remove stacked inclusion from machine automatically, and after piling up by automatic bundling, automatic ejection, transmission or whereabouts that the page or leaf sheet piles up.

So far each example has related to the processing spacer.Yet as described in previously, the invention still further relates to shown in following example more generally document process.

As shown in Figure 7, be supported on storage location 321 such as document package such as banknote cartridges 320.Roller group 301,302,303,305,306 is non-rotating to be installed between the side plate (not shown in figure 1) of equipment and to extend on each.As shown in Figure 7, several high friction pick-up rollers 301 (though single this roller only is shown) are installed near the storage location 321, make that the leading banknote in roller 301 and the cartridge is harmonious.To force banknote to prop up roller by the biasing device (not shown).

First picking up system 322 is by roller 301 and stipulated that the one or more pairs of crew-served separate roller 305,306 of roll gap forms (can only see a pair of among Fig. 1) between them.The forward roller 305 that separates is installed on the 305a, this is supported in the bearing that is installed in each side plate, and it outside side plate extended spot by the single channel power-transfer clutch with toothing arranged, have the tooth pulley to be driven by inhour from one, this pulley is fixed to by on driven 301a of pick-up roller electric motor drive system inhour.When or clickwise inoperative from the driving of axle 301a, the single channel power-transfer clutch make a 305a can by by downstream transfer system (not shown) between the roller 305,306 downwards the document inhour of pulling turn.The whole periphery of roller 305 has high friction surface.Separate tooled joint roller 306 and be installed on the 306a, this rotation is installed in the bearing that is installed in the side plate.These rollers by to the tooled joint of separate forward driven roller 305 by the cw friction-driven, yet also apply counter-clockwise moment by additional electrical motor (not shown) axle drive shaft 306a.Do not having document (or single document) when existing, this electrical motor moment is overcome by the counter-clockwise tooled joint moment that effect applied of separate forward driven roller 305.When a plurality of documents that comprise two or more documents were attempted by the supply of separation tooled joint, axle 306a went up counter-clockwise direct motor drive moment greater than the friction-driven between the document.Thereby a plurality of documents are separated and only allow the document contact with separate forward driven roller 305 to move ahead by exporting 302 tooled joint.

When working, roller 305 anti-clockwise rotations are so that supply with a page or leaf sheet in arrow 323 directions, and at this moment when not having or single document when being introduced into tooled joint, roller 306 is driven by cw by the tooled joint of roller 305, and reverse when a plurality of documents are introduced into.

Second picking up system 324 is formed by roller 301 and one or more pairs of separate roller 302,303.

Be installed in the separate forward driven roller 302 on the suitably rotatable axle 302a that is supported in the side plate centre bearer, by one independently the electrical motor (not shown) driven by inhour by the single channel power-transfer clutch, and can need not the separate drive motor useful effect by being turned by the document inhour of downstream transfer system (not shown) from pulling between the roller 302,303.The whole cylindrical of roller 302 has high friction surface.

Separate tooled joint roller 303 non-rotating being installed on the 303a, this is supported in the bearing that is installed in the side plate (not shown).This roller be by to the tooled joint cw of separate forward driven roller 302 by friction-driven.This electrical motor moment is overcome by separate forward driven roller 302 inhour tooled joint moment when not having document to have (or single document).When a plurality of documents that comprise two or more documents were attempted by the supply of separation tooled joint, axle 303a went up counter-clockwise direct motor drive moment greater than the friction-driven between the document.Thereby the separated and document that only allow to contact with separate forward driven roller 302 of a plurality of documents moves ahead and passes through to document and export 301.

Breakaway-element 304 is encased in the base plate of the equipment of the document that is placed with use on it, and when the master by them picks up the feeder supply, is used for separating document.Breakaway-element 304 keep and provide to the support of general feeder bonded assembly document.They can be integrated into general feeder, though they are the document container (such as the document cartridge) that apply usually.

Each picking up system 322,324 has sensor 308,307 separately, is used to produce and detect the light beam that interrupts of passing through by document.Sensor is connected to a control system (not shown), this control system control is used to turn the electrical motor (also not shown) of picking up system, in case an in a single day feasible or page or leaf sheet has been supplied with or the not further page sheet of process control system indication will be supplied with, picking up system is invalid.In addition, whether sensor 307,308 also detects has more than one banknote to transmit by separate roller 305,306 or 302,303, in this case, one process control system sign is set, so that or cause that feed system stops to supply with, cause that perhaps the downstream transfer structure makes a plurality of banknotes turn to as pick-out thing, or the number of definite a plurality of banknotes that sent, any combination of these actions perhaps born.

In order to detect the feature of banknote, checking system 309 is provided, this checking system has and piles the adjacent sensor of top page or leaf sheet in 320, so that determine one or more features when the page or leaf sheet is static basically, such as pattern (for example denomination), evaluation, applicability.

In use, relevant with the cartridge type that is positioned at storage location 321, or picking up system 322 or picking up system 324, perhaps two picking up system will be started by control system selectively, this system start-up pick-up roller axis drive motor is so that oppositely turn at cw or inhour.Under each situation, process control system receives or is provided by operator's input, perhaps data that provide by system input or any known structure, for example bar code, detection of electrons, hardware connection, magnetic code, smart card etc., they make packing put type by or can discern process control system.Defer to the instruction in the process control system, perhaps when picking up system 322 effectively the time roller 301 started by inhour, perhaps roller 301 is started by anticlockwise direction when picking up system 324 is effective.

As shown in Figure 7, from pile 320 pick up after, document is supplied with (by unshowned device) to optional public drive access 326, so that led to their last targets afterwards along each path.

In another kind of structure (not shown), document can offer the different target of effectively determining according to which picking up system 322,324.Under this situation, control system can respond the information from detector system 309, so that start suitable one of picking up system 322,324.

Can the representative type operating mode be described by one of picking up system or both from the structure of the general cartridge of its extraction now for relating to banknote:

1. just check the checking system 309 of face of document on the surface that is static bag 320 basically, process control system send supply with order drive with instruction motor supply with roll shaft 301a before rotating during, detect the feature of banknote surface.Though checking system can be configured to provide about denomination, evaluation, and the information of applicability, it provides evaluation/applicability data for the purpose of this example.

2. detector system concludes that document is real and suitable.Process control system is provided with sign, so that start the banknote of feed system sensing in direction 323.

3. pick-up roller 301 inhours that contact with document package 320 are rotated, and document package 320 is for example pressed to pick-up roller by the spring pressure (not shown).Thereby, realized preliminary " picking up " and document by on draw and its leading edge points to the tooled joint of piece-rate system roller 305,306.Before second document can be picked, by from zero to transfer rate (or just being lower than) and get back to zero and quicken pick-up roller 301 and obtain preliminary separation.Document transmits not illustrate but be designated as and illustrates 302.

4. document the document that sensor 308 determines when supply occurs and has removed feed system 322, and labeling process control system feed system has been prepared to supply with next document from wrapping 320.

5. in addition in step 302, detector system concludes that document is inapplicable, and process control system is provided with sign so that start the banknote of feed system sensing in direction 325.

6. under this situation, clockwise rotate realization preliminary " picking up ", so that the leading edge of document points to the tooled joint of roller 302,303 by pick-up roller 301.

7. document the document that sensor 307 determines when supply occurs and has removed feed system 324, and labeling process control system feed system has been prepared to supply with next document from wrapping 320.

Sum up:

Checking system was assessed document before picking up.(in above-mentioned option, authenticity and applicability information are the parameters of general feeder requirement, to determine which output document points to.)

By the inhour rotation and the concerted action of relevant treatment piece-rate system of pick-up roller 301, pick up the document that is suitable for further downstream, so that document is shipped to output 302 (arriving the interface of the processing transmission of main system).

Clickwise by pick-up roller 302 and relevantly return the piece-rate system concerted action is unsuitable for the document of further downstream, so that document is shipped to output 301 (to the interface of the echo-plex of main system).Certainly, above example has been described, using general feed system and having general cartridge, be used for sorting out the related process of detector system that is not suitable for the specific purpose document from those documents that detects to being fit to this purpose as basic document separator system.Under this situation, two document sets are sent to different targets.

Be output as output 302 though described system has stipulated to be used to handle, and be used to return and be output as output 301, if the output function reverse system is equal actv..

" selecting " possibility of N/R document in the feeder input, make this pattern of fully popularizing of general feeder, for requiring to savings/circulator from the system of import of services and for the low speed classification application, is a kind of desirable input medium.

Fig. 8 illustrates, when DPS together uses with the document cartridge that is applicable to reciprocal vacuum pick feedway, and the actv. assembly.Under this situation, only use picking up system 324.

In this example, three pick-up rollers 301 shown in Fig. 8 A (with two pairs of relative separate rollers 302,303 together).In Fig. 8 A, can find out, on the axle 302a that supports in the roller 302 non-rotating bearing (not shown) that are installed in the side plate 330,331.On the axle 303a that supports in the roller 303 non-rotating bearing (not shown) that are installed in the side plate 330,331.Roller 301 is supported on the axle 1a that extends between the side plate 330,331 by non-rotating, and they are supported in the support of these sidewalls.

In addition, sensing system 315 produces the light beam upstream of rollers 302,303, so that detect the existence of document, and causes that process control system is turn-offed and picks up electrical motor, and keep separate drive motor axle drive shaft 302a.Like this, when having caused the document of a plurality of supplies, separate roller 302,303 is prevented from, and detect by sensor 307 and should work as when being the single document of document of unique supply, motor drive shaft 302a causes that roller 302 transmits the next document of a plurality of supplies by the separate roller system.For example adopting detector 309 to detect under the situation of surperficial file characteristics, independent electric motors can be turned off and and then return to assist detector processes and/or to provide suitable document to the interval of the document between the document that leaves spacer roller system, this action is proceeded, till sensor 315 detects document and no longer occurs.

As described above in connection with Figure 7, roller 302 from can the forward direction flywheel pick up electrical motor by gear drive (perhaps can by independent isolating thing direct motor drive).Roller 303 receives the counter-clockwise moment that is applied by additional DC electrical motor (not shown), but is appeared in the tooled joint up to a plurality of documents by the driving of roller 302 cws.

Fig. 9 illustrates, the actv. assembly when DPS is used for from friction supply design-calculated cartridge supply document.Shown in Fig. 9 A, roller 305 non-rotating being installed on the axle 305a that extends between the side plate 330,331, its axis is by supported.Roller 306 non-rotating being installed on the axle 306a that extends between the side plate 330,331.

As preceding, detector 308 detects passing through of documents, and be used for controlling and driving pick-up roller 301 pick up the electrical motor (not shown).

At last, Figure 10 illustrates the opposite pattern of Fig. 8 example that is fit to some situation.Identical label is used for the mark components identical, and we believe that the work of this system is self-explantory.

The position of detector 309 will be relevant with the type of employed document holder.Figure 30 5a and 305b illustrate a kind of vacuum feed document holder, and wherein the installation of vacuum feed roller 350 is stretched out by the end wall 352 of holder.Be pressed in end wall 352 on the banknote (not shown), their interarea and vacuum furnace 350 are harmonious.One of pair of detectors 309A, 309B are installed in the end wall on another, so that check the surface of leading banknote, and vacuum pad 354 also have been installed so that open end wall shown in Figure 11 b.In use, the vacuum that is applied to vacuum pad 354 is cut off when outwards supplying with by exporting for 326 (as known) at banknote, and or when supplying with when banknote static state is in the holder or outside banknote, detector 309A and 309B can be from the most leading banknote acquired informations.As preceding, this can be used for controlling the banknote final objective.

In the example of Figure 11, detector 309A, 309B reflects.Figure 12 illustrates transmission structure.Under this situation, the banknote (not shown) in the holder is supported on to supply with on the plate 360 and by an elbow roller (not shown) and promotes forward in common mode.Minimum document is supplied with and is entered donor rollers to the roll gap between 362,364, static simultaneously or at a slow speed counting machine rotate separate roller 366 and prevent to supply with more than a page or leaf sheet or document.Radiant 368 generation radiation beams, this radiation beam is detected by detector 370 when the most leading document is supplied with by the roll gap between the roller 362,364, and this allows the feature of the document of supply, existence such as two documents, its state identifies that pattern etc. can be detected.

Under other situation, alternate source 368/ detector 370 structures can be installed two reflection detector/source structures at the opposite side of feed path.Can also use single reflection coefficient meter.
