Description
Technical Field
The present invention relates to a document conveying apparatus that conveys a document.
Background
In recent years, there have been known an image reading apparatus and an image forming apparatus in which an ADF (automatic document feeder) that automatically conveys documents is provided on a document platen, and documents that are sequentially conveyed by the ADF are read by an image sensor. The ADF takes in originals placed on an original tray one by one, feeds the originals onto a conveying path provided inside, and reads an image of the original passing through the conveying path with an image sensor provided so as to face the conveying path. Then, the original document on which the image is read is discharged to a discharge tray. The conventional ADF can detect occurrence of multi-feeding of two or more documents and can stop the feeding operation and the image reading operation of the documents when the multi-feeding is detected
In the document feeding apparatus, a phenomenon of document double feed often occurs, and when document double feed occurs, it is one of the main subjects of the multi-function peripheral manufacturers to reduce unnecessary operation time of the client by reducing the unnecessary operation of the client and improve efficiency.
There is known a technique in which, when an error such as a paper jam occurs when a document is fed and an image is read, a user manually or automatically returns the document to a document tray and performs rescanning in order to feed the document again (japanese patent laid-open No. 2009-177386). Further, there is known a technique of setting a flag to an image that has been read incorrectly, discharging a double-fed document to a different discharge tray, and then inserting the image data obtained again into a correct page position in an image memory to replace the image (japanese patent application laid-open No. 2011-. Further, there is known a technique of comparing images before and after an error occurs and determining whether or not scanning is required again (japanese patent laid-open No. 2008-252384).

However, in the conventional technique, there is a case where a document whose image has been correctly read even if an error has occurred is a target to be scanned again. In this case, the user may perform an extra operation such as re-feeding the original document that does not need to be scanned again by placing the original document on the tray again, which may reduce the work efficiency.
In addition, in the conventional technique, the original is conveyed again and the image is read again only when the image reading is in trouble, and how to reduce the time for reading the image again according to the specific situation when the conveyance error occurred before is not considered, so that the efficiency is relatively low and there is room for improvement.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a schematic block diagram for explaining a control system of an image reading apparatus including a document conveying device according to an embodiment of the present invention. Fig. 2 is a schematic sectional view for explaining a basic configuration of the image reading apparatus.
As shown in fig. 1, the image reading apparatus according to the present embodiment includes a CPU50, a ROM51 that stores control programs, data, and the like, a RAM52 that records data of the control programs, image data, and the like, a reading image forming unit 55 that reads information such as an image on a document and forms an image, a document conveying unit 56 that conveys the document to the reading image forming unit 55, an operation unit 3 that allows a user to perform an input operation, and a display unit 4 that notifies the user of image information that needs to be fed and read again on an operation interface. Of these, the CPU50 corresponds to a control unit, and the ROM51 and the RAM52 correspond to storage units.
In the present embodiment, the image adding means 57 and the mark applying means 58 are further provided. When an error such as double feed occurs and the document that needs to be reread is reread, the image complementing section 57 inserts or replaces the reread image with the image of the document stored in the storage section, thereby complementing the read image. As one implementation, for example, a normal image memory and a retransmission image memory may be provided in the storage unit. When the re-read of the re-fed document is performed, the image data obtained by the re-read is stored in the re-fed image memory, and the image data stored in the re-fed image memory is inserted into an appropriate page position in the normal image memory. The specific method used for the image insertion or replacement process may be various, and for example, the technique disclosed in patent document 2 (japanese patent application laid-open No. 2011-.
The mark applying unit 58 is a mechanism for applying a mark to each piece of document information stored in the storage unit. Specifically, during conveyance of originals, the storage unit stores original information for each original being conveyed before an image has not been read yet. The reread flag f (flag) is given to each document information by the flag giving unit 58. The reread flag F is a flag indicating whether or not the page of original document needs to be reread with image data. In the present embodiment, the reread flag F is expressed by a flag variable having a value of 0 or 1. For example, the mark applying unit 58 sets the initial value of the reread mark F to 0 for each document. When a conveyance error is detected during conveyance of the document and the page of document is determined to require re-reading, the flag applying unit 58 sets the re-reading flag F to 1. The specific setting mode will be described in detail later with reference to fig. 4 and 5.
In the present embodiment, the display unit 4 is used to display a setting screen, a message for the user, and the like. For example, when double feed detection sensor 562 determines that an error of double feed of the original has occurred, display unit 4 displays a message or the like notifying the user that double feed of the original has occurred. In addition, the user can be notified by means of an image, voice, or the like. The means for notifying the user is various, and any means may be used as long as the above-described function can be realized.
In the present embodiment, a document type determination unit for determining whether or not documents of different sizes are placed on the document placing portion may be further provided. When the document type determination section determines that documents of different sizes are placed on the document placement section, the relevant detection signal is transmitted to the control section.
Here, the document feeding unit 56 in the image reading apparatus will be described in detail. Since other units are well known to those skilled in the art, detailed description thereof will be omitted.
As shown in fig. 2, the document conveying unit 56 includes a normal discharge roller 561, a double feed detection sensor 562, a skew detection sensor 563, a pickup roller 564, a feed roller 565, a registration roller 566, a front reading roller 567, a rear reading roller 568, a guide rail switching gate 569, a double feed discharge roller 570, a normal discharge tray 571, a double feed discharge tray 572, and a document table 573 on which a document is placed.
First, the original to be read is taken in one by the pickup roller 564, and the paper feed roller 565 sorts the original and conveys it one by one to the conveyance path in sequence with a gap left.
A double feed detection sensor 562 is disposed downstream of the paper feed roller 565 in the document conveying direction. The double feed detection sensor 562 is a sensor for detecting whether or not double feeding of the original has occurred in the original conveying path. As shown in fig. 3, when an ultrasonic sensor is used as the double feed detection sensor 562, the double feed detection sensor 562 is arranged to include an ultrasonic wave generation section 5621 and an ultrasonic wave reception section 5622 that face each other across the document conveyance path. That is, the original document passing through the paper feed roller 565 passes between the ultrasonic wave generating portion 5621 and the ultrasonic wave receiving portion 5622. When the original designated for conveyance is picked up by pickup roller 564, the next original next to it is also picked up together due to factors such as friction of the original or pressure of the roller, causing a jump in the level of double feed detection sensor 562. The ultrasonic wave generating section 5621 irradiates the original with ultrasonic waves, and when the original is fed again, the ultrasonic waves are greatly attenuated due to the gap between the two sheets of paper, so that the intensity of the acoustic wave received by the ultrasonic wave receiving section 5622 is low, and the corresponding voltage amplitude is also low. The double feed detection sensor 562 receives the ultrasonic signal having passed through the document, converts the ultrasonic signal into an electric signal, and outputs the electric signal to the CPU 50. The CPU50 calculates the transmittance using the electric signal. The CPU50 determines whether or not multi-feeding has occurred based on the transmittance. Note that, although the ultrasonic sensor is described as an example, any sensor may be used as long as it can detect double feed of a document. In addition, there are cases where documents of different widths are conveyed, and in this case, the timing of detecting double feed coincides with the mode of conveying documents of uniform width. This function is to cope with the demand for multi-size original conveyance on the market. For example, when the customer has both A3 and a4 in the original.
Further, a skew detection sensor 563 is disposed downstream of the heavy feed detection sensor 562 in the document conveying direction. The skew detection sensor 563 is a sensor for detecting whether or not the document is skewed. In the present embodiment, it is configured to determine that a skew has occurred in a document when the angle of a read image on the conveyed document with respect to an ideal image (where no skew has occurred) is 3 degrees or more. The skew detection sensor 563 outputs a detection signal to the CPU 50. In the present embodiment, the description has been given taking the example of more than 3 degrees, but the present invention is not limited thereto, and the determination method may be appropriately selected by those skilled in the art as needed in practice as long as the skew of the document can be reliably detected.
A registration sensor, not shown, detects the presence or absence of a document passing through the conveyance path and outputs a detection signal to the CPU 50. In accordance with an instruction from the CPU50 in accordance with the detection signal, the registration roller 566 adjusts the conveyance timing, and the original is sent to the pre-reading roller 567. The document is sent out to the reading image forming unit 55 by the pre-reading roller 567. In the reading image forming unit 55, an image of an original is read and sent to a reading rear roller 568.
A guide rail switching door 569 is disposed downstream of the read rear roller 568 in the document conveying direction. The guide switching door 569 is driven by a drive motor, not shown, in accordance with an instruction from the CPU50, and discharges the fed original document to the normal discharge tray 571 via the normal discharge roller 561 or to the heavy discharge tray 572 via the heavy discharge roller 570. Specifically, when the CPU50 determines that double feeding of the original document has occurred based on the signal transmitted from the double feed detection sensor 562, the guide switching door 569 switches so that the original document is discharged from the double feed discharge tray 572 via the double feed discharge roller 570. On the other hand, when the original conveyance is normal, the guide switching door 569 switches so that the original is discharged from the normal discharge tray 571 via the normal discharge roller 561. Here, the rail switching gate 569 is merely an example, and any method may be employed as long as the documents can be sorted into the normally conveyed document and the double-fed document and discharged separately.
In the present embodiment, the conveyance error occurring during the conveyance of the document includes an error type and error information. The error type includes, for example, a paper jam, a double feed of a paper, a skew of a paper, a system error, and the like, and the error information includes whether or not the several sheets of paper are skewed or skewed and the sheets of paper have different widths when the skew or skew is generated. When a double feed error occurs, it is necessary to feed the double fed document again, and determine whether or not image supplement or replacement is necessary after comparing the documents of the preceding and following pages. The specific mode will be described in detail later. Further, for the detection of documents having different width sizes, a document type determination section may be provided to determine whether or not documents having different sizes are placed on the document placing section.
Next, a specific flow of document reading in the present embodiment will be described with reference to fig. 4. Fig. 4 is a flowchart showing a specific procedure of document reading according to the present embodiment. First, when the power of the image reading apparatus is turned on and a reading operation is performed by a user, the image reading is started.
First, in step S10, conveyance of the document is started. Next, in step S11, it is detected whether or not a conveyance error has occurred during conveyance of the document. When the conveyance error is not detected, the original is conveyed to the reading image forming unit 55 to read the image, and the process ends.
In addition, when a conveyance error is detected in step S11, the process proceeds to step S12, and it is determined whether or not the conveyance error is a paper jam. If it is determined that the jam has occurred, the process proceeds to step S13, where a reread flag F of the jammed document is set to 1, and the process proceeds to step S14. In step S14, a jam process is performed, specifically, the sheet on which the jam occurred and the following documents are manually set again on the document mounting tray and read again. Then, the process ends.
When it is determined in step S12 that the conveyance error is not a jam, the process proceeds to step S22, and it is determined whether or not the conveyance error is a double conveyance of the original. If it is determined in step S22 that the document is not double fed, the process proceeds to step S102, and other error processing, such as a system error, is performed.
If it is determined in step S22 that the document is double fed, the process proceeds to step S23, where it is determined whether the document is offset/skewed. When it is determined that the document has been shifted/skewed, the process proceeds to step S24, where it is determined whether the document whose shift/skew has been generated is the first page of the double-fed document. If it is determined that the document is not offset/skewed, the process proceeds to step S31, and it is determined whether or not the document is a document of a different size.
Here, with reference to fig. 5, a case will be described in which a different mode of setting a flag is adopted depending on the case where double feed of a document occurs. Fig. 5 is a schematic diagram showing a mode of setting a flag differently in various situations when double feeding of a document occurs. In fig. 5, a document in which double feed has not occurred is denoted by a, a first page of the document in which double feed has occurred is denoted by B1, and a second page is denoted by B2. In the present embodiment, description will be made taking an example in which two-page double feed occurs (B1 and B2). In fig. 5, an arrow indicates the conveyance direction of the document, and a triangle indicates the double feed detection sensor 562. In fig. 5, an example of whether or not documents of different sizes are included and whether or not a document is skewed when double feed occurs is described.
Fig. 5(a) is a schematic view showing a case where double feed has occurred, and the document is not skewed and does not include documents of different sizes. As shown in the drawing, in this case, since the originals a and B1 can be read normally, a flag is set only to B2 to be read again, and is discharged to the double feed discharge tray 572.
Fig. 5(a) is a schematic view showing a case where double feed has occurred, skew has not occurred in the original, and the original whose double feed has occurred includes originals having different sizes. As shown in the drawing, in this case, since the size of the original is changed, the originals B1 and B2 cannot be distinguished, and therefore it is necessary to set a flag to both B1 and B2 to be read again and discharge both B1 and B2 to the double feed discharge tray 572.
Fig. 5B is a schematic diagram showing a case where double feeding has occurred and a document B1 (first page of double-fed document) is skewed. As shown in the drawing, in this case, since document B1 is skewed and the image cannot be read normally, and document B2 is double fed and the image cannot be read normally, it is necessary to set a flag to both B1 and B2 to make a re-reading scheduled, and to discharge both B1 and B2 to double feed discharge tray 572.
Fig. 5C is a schematic diagram showing a case where double feed has occurred and the document B2 (second page of double-fed document) is skewed. As shown in the drawing, in this case, since the original B1 can normally read an image, and the original B2 is double-fed and skewed, and the image cannot be normally read, a flag is set only to B2 to make re-reading scheduled, and B1 is discharged to the double-fed discharge tray 572.
Fig. 5D is a schematic diagram showing a case where double feed has occurred and both of the documents B1 and B2 (the first page and the second page of the double-fed document) are skewed. As shown in the drawing, in this case, since the original B1 is skewed and the image cannot be read normally, and the original B2 is double fed and skewed and the image cannot be read normally, it is necessary to set a flag to both B1 and B2 to make a re-reading scheduled, and to discharge both B1 and B2 to the double feed discharge tray 572.
Although the description has been given with respect to the double fed document as 2 pages, the double fed document is not limited to this, and may have a number of pages of 2 or more. In this case, the same method as the above-described method of setting the flag may be adopted.
Next, returning to fig. 4, when it is determined in step S24 that the skew has occurred on the first page of the double-fed document, the flow proceeds to step S25, in which a flag is set on all of the double-fed documents including the first page of the double-fed document in the manner described above, and the double-fed document with the flag set is discharged. After the double-fed document is discharged, the flow proceeds to step S50, where the user is notified. The notification to the user can be made using the display unit 4 described earlier. If it is determined in step S24 that the document is not the first page of the double fed document and the skew has occurred, the process proceeds to step S27, and only the double fed document after the second page of the double fed document is marked in the manner described above, and the double fed document with the marked double fed document is discharged. After the double-fed document is discharged, the flow proceeds to step S50, where the user is notified.
If it is determined in step S31 that the document is a document of a different size, the process proceeds to step S32, in which a flag is set for all double-fed documents including the first page of the double-fed document in the manner described above, and the double-fed document with the flag set is discharged. After the double-fed document is discharged, the flow proceeds to step S50, where the user is notified. When it is determined in step S31 that the document is not a document of a different size, the process proceeds to step S34, and a flag is set only on the double fed document after the second page of the double fed document is started, and the double fed document with the flag set is discharged, in the manner described above for setting the flag. After the double-fed document is discharged, the flow proceeds to step S50, where the user is notified.
In step S50, the user is notified of information relating to the double fed document using the display unit 4, and the process ends.
The configuration of the present embodiment is specifically described above. When a conveyance error is detected by the conveyance error detection unit, the method of setting the mark on the conveyance error document is determined based on the error type or error information of the conveyance error, and the conveyance error document is read again based on the set mark to complement the image data of the document. Therefore, the waiting time of the user can be shortened.
Further, since the configuration is such that it is determined whether or not there are documents of different sizes placed on the document placing section, and when it is determined that there are documents of different sizes and it is determined that a double feed error including the documents of different sizes has occurred, a flag is set to all pages of the conveyance error document, and otherwise, a flag is set to the documents including the second page and subsequent pages of the conveyance error document, it is possible to correct an image without omission, and it is possible to improve convenience for the user and shorten the processing time at the same time.
Further, a program for performing the operation in the image forming apparatus can be provided. Such a program can be provided as a program product by being recorded on a computer-readable recording medium such as a floppy Disk, a CD-ROM (Compact Disk-Read Only Memory), a ROM (Read Only Memory), a ram (random Access Memory), and a Memory card attached to a computer. Alternatively, the program may be provided so as to be recorded in a recording medium such as a hard disk incorporated in the computer. In addition, the program may be provided by downloading via a network.
Among the program modules provided as part of the Operating System (OS) of the computer, the program of the present invention may be configured to call necessary modules at a predetermined timing in a predetermined arrangement to execute processing. In this case, the program itself does not include the above-described module, and executes the processing in cooperation with the OS. Such a program containing no module may be included in the program of the present invention.
