As shown in Figure 1, the present invention comprises one first file path 11, have an ADF feed-in roller 15, a guide 12, one two-way roller 17, transducer (sensor) S3, S2, S1 and an imageing sensor (image sensor) 16, for example CIS on this file path 11.Transducer S1, S2, S3 belong to the transducer of tactile (touch-activate).The inlet of this first file path 11 defines a document entry 110, and when first file path 11 came into force, a multi-functional opening 112 was the file exporter for this first file path 11, and this point will be illustrated more clearly in the back.The function of transducer S3 is whether induction is positioned at document entry 110 and has file to exist.When desiring forward to scan, that is file is directed to multi-functional opening 112 by document entry 110, and operating personnel are inserted in file in the document entry 110.The function of transducer S2 is whether sensing has file to exist between roller 15 and roller 17 on first file path 11.In addition, during file moved along first file path 11, this transducer S2 informed that controller (not demonstrating) file has arrived at the position of transducer S2.This controller is according to this information, and the action of control roller 15 is so that this document can arrive the scanning position of these imageing sensor 16 belows exactly.Whether transducer S1 sensing is positioned at multi-functional opening 112 has file to exist.File is guided via first file path 11, and is indicated as the arrow among Fig. 1.When scan operation forward, roller 15 is with counterclockwise and roller 17 is driven in a clockwise direction simultaneously.Be positioned at transducer S1 below and showed a gradient near the surface of shell of multi-functional opening 112, as shown in Figure 1, this gradient helps to discharge by the file behind the scanning position 16, and simultaneously, this gradient can prevent that here forward scanning document triggers this transducer S1.Near the file exporter 132 surface of shell has also been showed a gradient, and as shown in Figure 1, it allows the reverse scan file to discharge.Only file sting via multi-functional opening 112 feed-ins and by roller 17 and situation under the reverse scan file could trigger transducer S1.It should be noted that in operation during present embodiment that forward scanning desired short essay spare length must be greater than the path distance of 17 on roller 15 and roller.
After forward scan operation begins, in file pile up the superiors file will via between the slot of 18 of feed-in roller 15 guide pads corresponding with it by the interior space of feed-in ADF.Subsequently, the file of this feed-in moves along aforementioned first file path 11, and by roller 15 operation counterclockwise, and the file of this feed-in is loaded into position to be scanned.When scan operation forward, document flow is through between the slot of two-way roller 17 with imageing sensor 16 lower surface, and is discharged to the outside of image processing system housing 19.It should be noted that when file when this first file path 11 moves, this two-way roller 17 is played the part of a role who discharges roller, it is expelled to file the outside of housing 19 via multi-functional opening 112.
Also as shown in Figure 1, the present invention comprises one second file path 13 for the reverse scanning operation, and second file path 13 is defined by guide 12, two-way roller 17, transducer S2, transducer S1 and imageing sensor 16.This reverse scanning operation is directed to file exporter 132 with file by multi-functional opening 112.This multi-functional opening 112 is the inlet of second file path 13, and file exporter 132 is the outlet of second file path 13.This transducer S1 is the file that sensing is positioned at multi-functional opening 112, and informs that controller (not demonstrating) this document has been ready for and can carry out reverse scanning operation.According to this information, controller impels the action of roller 15 to lose efficacy, and therefore, the file of transducer S3 institute sensing will can so, can not prevented file blocking by feed-in first file path 11.The reverse scanning file is guided via second file path 13 shown in Fig. 1 arrow.When reverse scanning was operated, roller 17 followed and counterclockwise is driven, and roller 15 is then kept motionless.
When the reverse scanning operation start, individual file is by the slot of feed-in between 16 of two-way roller 17 and imageing sensors.When imageing sensor 16 carried out file scanning, this document was flowed through between the slot of two-way roller 17 with imageing sensor 16 lower surface, and then, this document is discharged to the outside of image processing system housing 19 along second file path 13 shown in Figure 1.We must note: when file when second file path 13 moves, two-way roller 17 is at first played the part of the role of a feed-in roller, then, plays the part of the role who discharges roller is expelled to file housing 19 via file exporter 132 outside.
It is overlapping that we can be observed the part of the part of aforementioned first file path 11 and aforementioned second file path 13, defines an overlay path by this.In example, when the user chose this first file path 11, these multi-functional opening 112 functions were as file exporter, if the user chooses this second file path 13, the function of this multi-functional opening 112 then becomes document entry.Can use total imageing sensor in order to make forward with the reverse scanning operation, this illumination/scanning position is positioned at the predefined position along overlay path.This predefined illumination/scanning position is positioned at the below of imageing sensor 16.
Fig. 2 has disclosed Fig. 1 detailed description operation sequence of the present invention.Square frame 201 opens stage beginning for start.In square frame 202, whether this program detecting sensor S1, S2 or S3 are triggered.If any transducer is detected in square frame 202, so in square frame 204, this program will judge whether that transducer S1 and S2 all are not triggered.
If transducer S1 and S2 all are not triggered in the square frame 204, march to square frame 209 to be written into by the file of transducer S3 institute sensing.If not being judged as not in square frame 204, then the file of being left in the file overlay path during with previous scan operation in square frame 206 is discharged.DOP detailed operating procedure in the square frame 206 then is disclosed in Fig. 3.Then, in square frame 208, this program detects file discharge banner (paper-out flag) and whether is set (set).Be not scanned when promptly discharging in a file, this document is discharged banner and can be set, and this can be with reference to the detailed description of relevant Fig. 3.If square frame 208 is non-(no), carry out square frame 209, to be written into the file that is sensed by transducer S3.If square frame 208 is for being (yes), then program proceeds to square frame 203, and at this moment, program can be in wait state and be triggered up to any transducer.When any transducer was triggered, then program proceeded to square frame 205.In the present invention, because requiring (request) more forward to scan requirement (request), reverse scanning has higher priority, therefore, whether 205 detecting sensor S1 are triggered in square frame.
If in square frame 205 answers is sure, its represent a file via this multi-functional opening 112 by feed-in, therefore, in square frame 207, set reverse driving parameters so that driven roller 17 and interrupt the action of roller 15 counterclockwise.Then, program proceeds to square frame 209 to be written into by the file of transducer S1 institute sensing.If square frame 205 answers are negated that program proceeds directly to square frame 209 with deasil driven roller 17 and driven roller 15 widdershins, to be written into by the file of transducer S3 institute sensing.
After square frame 209 was sent file into scanning position, program proceeded to square frame 210 to carry out scanning imaging system.After finishing scanning, program proceeds to square frame 203.Particularly, carry out many files in the ADF when forward scanning since shown in the gradient design, will can not discharge and not trigger transducer S1 because of file.After last file was finished forward scanning and taken aim in ADF, program proceeded to square frame 203.
The detailed procedure that file is discharged then is exposed in Fig. 3.Whether square frame 301 detecting sensor S2 are not triggered.If be non-, represent a file to be present on the overlay path, program proceeds to square frame 303 changes move a step (step) with clockwise driven roller 17.Repeatedly implemented by square frame 301 and square frame 303 formed loops (loop), S2 is not triggered up to transducer, and at this moment, this document still must be driven a preset distance, and this preset distance equals the distance of transducer S2 to roller 17 summits.In other words, when transducer S2 was not triggered, program proceeded to square frame 302 and equals this predetermined steps numerical value with setting variable M, so that this document is discharged.This predetermined steps numerical value representative is discharged file in multi-functional opening 112, the step number that 17 palpuses of roller rotate.In square frame 304, rotary roller 17 1 goes on foot in a clockwise direction.Because roller 15 is driven simultaneously with roller 17 in the square frame 206, therefore, in square frame 305, whether this program detects owing to a follow-up feed-in file is delivered to transducer S2 S2 is triggered.If the answer in square frame 305 is sure, program proceeds directly to square frame 208 and does not discharge banner in square frame 308 enactment documents.It should be noted that, when discharge one is positioned at the file of overlay path, if because next feed-in file arrives at transducer S2, and it is sensed when being starting state in square frame 305 transducer S2, this file that is present in overlay path at first scans and is discharged from outside the housing 19, then, next feed-in file is written into mat square frame 209, to be carried out at further scanning motion in the square frame 210.If the answer of square frame 305 is for negative, then in square frame 306, parameter M will be subtracted 1.Then, in square frame 307, whether the value that program detects M is 0.If, then represent desire discharge file institute must the step number value finish, program then proceeds to square frame 308 with enactment document discharge banner.If the answer in square frame 307 is not, then the operation in the loop comprises square frame 304,305,306,307, will repeatedly be carried out.
