Description

  The present invention is caused by a jam or the like when an image transmission apparatus such as a facsimile, a scanner, or a composite apparatus having an image transmission function and a plurality of originals are automatically fed and read by the image transmission apparatus. The present invention relates to a control program when there is an interruption to be performed.

  In the prior art, as a recovery method when a jam occurs when a series of originals are scanned and copied using a copying machine having an automatic document feeder, the document has already been scanned based on the number of documents conveyed and the number of printed paper discharged. There is an instruction to return a certain number of original pages to the original setting position, and the remaining originals are set according to this instruction, and then restarted (see, for example, Patent Document 1).

  According to another conventional technique, when a jam occurs while a series of originals are being read by a digital copying machine, the series of originals are set again based on the number of pages of image data that has already been read, and the reading is completed. The original corresponding to the original that has been read only halfway due to the occurrence of a jam is erased, the original that has not been read is read, and the entire series is read. Image data corresponding to the page has been obtained (see, for example, Patent Document 2 and Prior Art of Patent Document 3).

In another conventional technique, when a jam occurs in the document feeder while reading a document, the last read document is displayed and this image is erased according to the state of the image. Yes (see, for example, Patent Document 4). Here, there is no description regarding processing of image data being read.
Japanese Patent Laid-Open No. 2-66586 JP-A-4-248761 JP 2000-89617 A JP-A-9-46490

  However, the technique of Patent Document 1 relates to an analog copying machine that forms a latent image on a photosensitive member using light reflected by exposing a document and transfers the latent image onto a sheet as a toner image. Since the discharge of the paper on which the toner image is transferred corresponds in real time, the number of pages returned from the original can be calculated from the read and discharged paper. Since this image data is transmitted after the number of pages or all the originals are read and stored as image data, even if the image data has already been read, when the technique of Patent Document 1 is used. It would be useless to read.

  Further, the technology of Patent Document 2 and the technology cited as the prior art of Patent Document 3 are digital copiers, which effectively utilize already read document image data and re-create the document without thinking about it. Although it has the advantage of being set and recovered, even if a jam occurs at the end of a large number of documents, it takes time to reset the document from the beginning, and to feed and scan it. Furthermore, I was worried that the originals before and after the jam were sent without missing.

  Furthermore, although it is a technique for solving the problems of the technique of the above-mentioned Patent Document 2 and the technique cited as the prior art of Patent Document 3, in this technique as well, the last read original is normally read normally. Often imposes unnecessary work on the user.

  According to the present invention, when a jam occurs in an automatic document reading apparatus, even if the image data is less than one page being read, the image can be read by storing it without deleting it and displaying this image data. The purpose is to inform the user of the missing page.

In order to achieve the above object, a first image transmission apparatus according to the present invention sets conditions for the transmission job in an image transmission apparatus that executes a transmission job for transmitting image data corresponding to a series of documents. In accordance with the operation display means, in accordance with the condition setting, the series of originals set on the original stacking means are fed one by one and sequentially fed to the original reading position. Document reading means for reading according to the condition setting, image storage means for sequentially storing image data of the read document in page units according to the condition setting, and image data of the read document stored in the image storage means for the image data a transmission control means for transmitting in accordance with the conditions set, causes interrupts the conveyance when said document feeding conveying means is conveying the series of original Stored when there, and an incomplete image data storage control means for storing in said image memory means without erasing an incomplete image data of less than one page corresponding to the read middle of the document page, in the image storage unit Display data generating means for generating display data from the displayed image data, display control means for displaying the display data for a plurality of images, and allowing selection of any of the displayed display data, and When any of the display data displayed by the display control means is selected, the recovery control means executes the transmission job according to the above condition setting, assuming that reading is resumed from the document corresponding to the selected display data It is characterized by having.

Second image transmission apparatus of the present invention, in the first image transmission apparatus, when the conveyance of the set of document is interrupted, when the absence the incomplete image data or the predetermined capacity or less, the display The display data generation unit generates blank display data, and the display control unit displays display data of a plurality of images including the blank display data, and any one of the displayed display data It is characterized by permitting selection.

  According to a third image transmission device of the present invention, in the first or second image transmission device, the transmission control unit selects the display data after the display data displayed by the display control unit is selected. The image data stored in the means is transmitted again from the first page.

The control program of the present invention causes the computer to display the operation display means for setting the conditions of a transmission job for transmitting image data corresponding to a series of originals and the series of originals set on the original stacking means one by one. Document feeding and conveying means for feeding and sequentially conveying to the document reading position; document reading means for reading the document at the reading position according to the condition setting; and image data of the read document in order of page according to the condition setting An image storage means for storing, a print control means for printing a plurality of image data stored in the image storage means in accordance with the condition setting, and when the document feeding and conveying means conveys the series of documents. When there is a cause of interrupting conveyance, incomplete image data that is less than one page corresponding to a document page being read is erased. Incomplete image and data storage control unit, and the display data generating means for generating display data from the image data stored in said image storage means, the display data of the plurality of images stored in said image storing means without the Display control means that allows selection of any of the displayed display data, and when any of the display data displayed by the display control means is selected, the selected display data Assuming that reading is resumed from the corresponding document, it is made to function as a recovery control means for executing the print job in accordance with the condition setting.

  For example, in the conventional technique described in Patent Document 2, incomplete image data when a jam of less than one page occurs is deleted and discarded. In the prior art described in Patent Documents 3 and 4, when a jam occurs in the document conveying device, the image data read last can be displayed and used for recovery or as image data. Whether or not. However, in this case as well, unlike the present invention, an incomplete image of less than one page is not used, but the image of the document read last is simply displayed among those stored as image data. It ’s just that. This method of use is sufficient for a reading method in which reading and scanning is performed with the document stopped on the platen. However, in a recent sheet-through type document conveying device or the like, if a jam occurs, In many cases, one original is being read while moving, and an image that is less than one page is not considered to be used as image data from the beginning.

  Therefore, if the first image transmission apparatus of the present invention is used, the operation display means and other functions are not performed by instructing the number of pages for returning the original when a cause of interruption of the original conveyance such as a jam occurs. If the same original as displayed on the operation panel is found and the subsequent original is set again, the correspondence between the original and the already read image becomes clear, and the recovery is correctly performed. On the other hand, if the original is appropriately returned and reset, and the display corresponding to the original of the first page is selected from the displayed images, the recovery is correctly performed as described above. This is particularly effective for a document that has a document stacking unit that can immediately confirm a document to be read first among the reset documents.

Further, in the conventional erase when the document transport is interrupted, that keep the image data read during the page of the document has been destroyed, the display data corresponding to said in the middle reading during interruption document It can be displayed, and the operator can be visually notified of the original document that actually caused the interruption. Further, it is useful for confirming the paper quality of a document that is easily jammed when a document composed of a plurality of types of paper is set. In addition, if these images are displayed, it is possible to check whether the original document that caused the interruption and its surrounding documents are printed correctly after the print job is completed in the recovery operation. There is also an effect of relieving the user's anxiety later.

  If the third image transmission apparatus of the present invention is used, the image of the last read document among the documents already read when the document conveyance is interrupted is displayed. When the transmission of the original image is completed, it can be confirmed whether the image is correctly transmitted. In particular, even when there is no document being read at the time of interruption, that is, when there is no incomplete image, it is possible to confirm whether the read original at the time of interruption is correctly transmitted.

  According to the control program of the present invention, it is possible to display an image corresponding to a plurality of originals and select an original from which a transmission job is resumed. Therefore, when an operator resets the original, the operator can easily understand and operate. become.

  An example of a composite apparatus as an image transmission apparatus employing the present invention will be described with reference to the schematic diagram of FIG. In the figure, this multifunction device 1 is a multifunction device having functions of a copy, a printer, a facsimile, and a scanner. A CPU (Central Processing Unit) 2, a ROM (Read Only Memory) 3, a RAM (Random Access Memory) 4 , Mail creation means 5, printer controller 6, printer unit 7, post-processing device I / F (post-processing device interface) 8, post-processing device 9, operation panel 10, scanner I / F (scanner interface) 11 , Scanner section 12, automatic document feeder 13, image storage means 14, bitmap memory 15, CODEC (coder / decoder) 16, modem 17, NCU (network controller) 18, public line 19, network I / F (network Interface) 20, bus 21, document stacking tray 27, etc. . The composite apparatus 1 is connected to a PC (Personal Computer) (24, 25) and a printer 23 via a network cable 22.

  The mail creating means 5 is used in the network scanner function, and is a means for creating an e-mail when the image data read by the scanner unit 12 is attached to an e-mail and transmitted to a destination registered in advance.

  The printer controller 6 analyzes the print command (PDL) and job information transmitted from the connected personal computer and stored in the reception area of the image storage means 14, and generates intermediate language information. This intermediate language information is stored in an intermediate language information storage area of the image storage means 14.

  The printer unit 7 sequentially sends the image data developed in the bitmap memory 15 to an optical device for writing a latent image such as LSU (laser scanning unit) or LPH of the image forming unit of the printer unit 7, and A toner image is formed in the image portion, which is sequentially transferred from a paper feed cassette to a paper that is fed and transported, and is fixed and discharged.

  The post-processing device I / F 8 and the post-processing device 9 are a post-processing device 9 that performs post-processing such as stapling and punching, sorting, sorting and grouping, etc., on the printed matter printed and discharged from the composite device 1. , An interface and a cable for connecting this to the main body of the composite apparatus 1.

  As shown in FIG. 2, the operation panel 10 includes an LCD display unit 101, which is a large LCD (liquid crystal display) device, a start key 102, a stop clear key 103, a reset key 104 (all clear key), an initial setting key 105, power saving. It consists of a plurality of operation keys such as a key 106. Since the image transmission apparatus is a composite apparatus, the operation display unit can switch the copy function screen, the printer function screen, the facsimile function screen, and the scanner function screen with a selection key on the left of the operation panel 10.

  The screen displayed on the LCD display unit 101 includes a basic screen of the network scanner function shown in FIG. 3 and a “user function screen” (function screen) when “user function” is selected from a plurality of tabs below this screen. 1) is displayed. Further, when the “function list” tab is selected, a “function list screen” (one of the function screens) is displayed. In addition, the screen can be switched to a printer function, network scanner function, or facsimile function screen. The operator of the multifunction machine 1 can set the conditions of a desired transmission job by operating the keys provided on the operation panel 10 and the LCD display unit 101. The conditions here are for transmitting image data obtained from a manuscript via an electric communication line such as a public line or a network cable, which will be described later. Size), image storage and transmission control (eg, transmission size, number of transmission bits, data format, etc.).

  The scanner I / F 11 is an interface for controlling the scanner unit 12 and the automatic document feeder 13 by connecting to the scanner unit 12 placed on the multifunction apparatus 1 via a cable.

  The scanner unit 12 conveys light by a halogen lamp or a fluorescent lamp to a document which is conveyed one by one by an automatic document conveying device 13 or placed on a contact glass, and then reflects the reflected light to a CCD (charge coupled device) sensor. The analog signal is converted into a digital signal by A / D conversion, image processing is performed in the image processing unit, and the image is processed in the subsequent bitmap memory 15. In the copy function, the analog signal is expanded in the bitmap memory 15. The image is encoded by the CODEC 16 and stored in the image storage means 14. In addition to the image data from the scanner unit 12, the bit map memory 15 includes intermediate language information generated by analyzing a print command transferred from a personal computer connected via a network or the like by the printer controller 6, and the other party. The image data sent from the facsimile 26 via the public line 19, the NCU 18, and the modem 17 is decompressed by the CODEC 16 as needed, and is expanded and held as full bit map image data. The CODEC 16 is also used for decoding the encoded image data included in the print data.

  The automatic document feeder 13 conveys a series of documents set on the document stacking tray 27 one by one to the document reading position, and then discharges them. The document reading position varies depending on the type of the automatic document feeder 13. For example, in the sheet-through type automatic document feeder 13, the document is exposed through a slit facing this position at the bottom of the document conveyance path, and the reflected light is read by a CCD sensor fixed near the slit. The document circulation type automatic document feeder 13 is on the contact glass. In this case, the image is read by scanning the CCD sensor in the same manner as in the case where the document is manually placed on the contact glass and copied.

  The image storage means 14 encodes and stores the image data read by the scanner unit 12 with the CODEC 16 when performing normal facsimile memory transmission and reserved transmission, in addition to the above-described copy function, received image area, and intermediate language area. . When the scanner function is used, the image data read by the scanner unit 12 can be transmitted to the external PC (24, 25) after being encoded by the CODEC 16, and similarly, the facsimile polling function can be used. It is also possible to transmit in accordance with a request from the other party's facsimile. As an image data storage element, in addition to the RAM 4, in recent years, an image memory is often used as an image memory using a relatively large capacity hard disk for storing image data.

  The modem 17 converts an analog signal transmitted from the public line 19 into a digital signal, and conversely converts the digital signal into an analog signal and transmits it through the public line, and performs modulation and demodulation. For example, only HDLC frames are received. The NCU 18 performs connection to the public line, switching between facsimile and telephone, sending an on-hook signal to the line, ring detection, and the like.

  The network I / F 20 is an interface that connects the composite apparatus 1 to the network. Here, it is connected via a network cable 22 to a personal computer (24, 25), a printer 23, and other connection devices not shown.

  The bus 21 is a bus for exchanging data and signals of each configuration described above. Although there are buses for image data and buses for control signals, they are represented by one for short here.

  The CPU 2 controls the operation and function of each component of the multifunction device 1 including the above of the multifunction device 1, and executes a transmission job in accordance with the condition setting. Here, the transmission job refers to a process in which the CPU 2 controls the operation and function of each component in order to transmit image data corresponding to a series of documents according to the above condition setting. Further, the CPU 2 is connected to a ROM 3 storing various programs including the control program of the present invention, and a RAM 4 storing user choice data, setting information, total count data, various font data, and the like.

  Particularly in the image transmission apparatus of the present invention, the CPU 2 includes a transmission control unit 201, an incomplete image data storage control unit 202, a print data generation unit 203, a display control unit 204, and a recovery control unit 208 as shown in FIG. Have. Each of these means 201 to 208 controls operations and functions that are characteristic of the image transmission apparatus of the present invention. Needless to say, the CPU 2 controls not only the operations of the respective units 201 to 208 but also the overall operations of the components of the composite apparatus 1.

  The transmission control unit 201 transmits a plurality of image data stored in the image storage unit 14 to a transmission destination specified by connecting a telecommunication line in accordance with the transmission job condition setting set on the operation panel 10. Here, the transmission includes transmission to an external receiving terminal connected by an electric communication line such as transmission by electronic mail, facsimile transmission, and image data transmission to a PC (24, 25).

  The transmission control unit 201 preferably interrupts transmission and disconnects the line when document conveyance is interrupted when transmission is performed each time one page of document is read. Direct transmission in a facsimile apparatus corresponds to this case, and unnecessary line usage charges are not required, and it is possible to avoid an unnecessary increase in the traffic volume of the line. On the other hand, when transmission is started after reading a series of originals, the line is not normally connected during reading of the originals. Therefore, the above problem does not occur, and after removing the cause of the interruption of the document conveyance, all the documents are read and then the line is connected to start transmission. In this case, memory transmission with a facsimile machine, PC transmission with a network scanner (method of transmitting image data to a personal computer terminal etc. via a LAN line, etc.), mail transmission (method of transmitting image data with mail attached), etc. It corresponds to.

  The incomplete image data storage control unit 202 reads the document while being conveyed by the automatic document conveyance device 13 and conveys the document while jamming, opening the cover, or turning off the power while being stored in the image storage unit 14. If there is a cause of interruption, the data stored in the image storage means 14 is not erased until halfway, but is stored as incomplete image data.

  The display data generation unit 203 generates display data from the image data stored in the image storage unit 14. That is, the image data is decoded by the CODEC 16 and developed in the bitmap memory 15. Next, in order to display the developed bitmap image data on the LCD display unit 101 of the operation panel 10, the size is adjusted and stored in the bitmap memory 15 as display data.

  The display control unit 204 instructs the display data generation unit 203 to generate display data for a plurality of document images that have been read when the document conveyance is interrupted. At this time, the display control unit 204 can select the document read last when it is interrupted as one of a plurality of documents. Further, the generated display data is displayed on the LCD display unit 101 of the operation panel 101. The display control unit 204 instructs the display data generation unit 203 to generate display data corresponding to the incomplete image stored in the image storage unit 14 by the incomplete image data storage control unit 202 described later. The display data for the generated imperfect image can be displayed. Further, the display control means 204 sets a message on the document stacking tray 27 after the first document to be read out of the series of documents after resuming the transmission job, and prompts the operator to instruct the transmission to be resumed. Is displayed on the LCD display unit 101. Here, the display control unit 204 allows selection of any of the displayed display data.

  When any of the display data displayed by the display control unit 204 is selected, the recovery control unit 208 assumes that reading has been resumed from the document corresponding to the selected display data, and transmits according to the above condition setting. The transmission control means 201 is instructed to execute. Here, if image data stored in the image storage unit 14 before resuming the transmission job is not yet transmitted, transmission may be started from the image data of that page. Of course, if all the image data stored before resuming the transmission job has been transmitted, the last image data has been transmitted. Transmission is started from the image data of the received document. In addition, in order to avoid a situation in which it is not possible to know who has been sent because the image data from the intermediate page is received at the transmission destination, the image data of the first page of the original is sent again. That's fine. When the transmission job is resumed, a plurality of the display data are displayed by the recovery display control means 204 and the above message is displayed. Therefore, if the operator sets a series of documents according to the display, the page that causes the interruption of document conveyance Reading is resumed from the original. For a document up to one page before the page corresponding to the selected display data after resuming the transmission job, the image data obtained by reading the image is erased, or the corresponding data stored before resuming the print job. Although it can be replaced with the image data of the page, it is preferable to skip the image without reading it.

  As an embodiment of the present invention, processing related to recovery when transmitting image data corresponding to a series of documents over a plurality of pages will be described with reference to the flowchart of FIG. First, a transmission job condition is set from the operation panel 10 (S201), a series of documents is set on the document stacking means 27 of the automatic document feeder 13 (S202), and the start key 102 is operated (S203). While feeding one sheet (S204), the CCD reads at the reading position while conveying the original. At this time, the analog image signal read by the CCD is A / D converted into a digital image signal, subjected to image processing, and developed in the bitmap memory 15. The image data developed in the bitmap memory 15 is encoded by the CODEC 16 and written into the image storage means 14 to be stored (S205). At this time, it is determined whether or not a jam or the like has been interrupted in the automatic document feeder 13 (S206). If there is no jam, it is determined whether or not all the documents on this page have been read (S207). If not, the process returns to S206. If the reading of this page is completed, it is determined whether or not there is a document for the next page (S208). If there is, the process returns to S204. Transmission is performed according to the above condition setting. At this time, the transmission control unit 201 connects the telecommunication line and transmits the image data to the transmission destination designated in S201. After the transmission of the image data of all the series of originals is completed, the telecommunication line is disconnected and the transmission job is finished (S209).

  In S209, the flow is such that the transmission is started after all the originals are read. However, in the case of direct transmission in the facsimile apparatus, a page that has been read may be transmitted as needed. In addition, if the setting is such that all pages of the original cannot be transmitted after the reading is completed (for example, direct transmission of a facsimile machine, PC transmission of a network scanner, or mail transmission), all the originals are temporarily stored in the image storage unit 14. Will be sent after storing.

  If an interruption such as a jam occurs in S206, the incomplete image data storage control unit 202 determines whether there is incomplete image data read halfway through the page of the document (S210), and there is incomplete image data. In this case, it is determined whether or not the incomplete image data is a predetermined size or more (S211). If the incomplete image data is a predetermined size or more, the incomplete image data is stored in the image storage means 14 without being erased. (S212). Since this predetermined size is such that it can be identified which document, 25% of the image data capacity of one page is sufficient. Subsequently, the display control unit 204 displays the incomplete image data for display generated from the incomplete image data with respect to the display data generation unit 203 and the two pages immediately before the document corresponding to the incomplete image. An instruction to generate an image is issued, and the display incomplete image data generated on the LCD display unit 101 and the display data for the previous two pages are displayed on the LCD display unit 101 as shown in FIG. In FIG. 5, as an example of the display form, an incomplete image, the first page immediately before, and the second page immediately before are displayed in order from the left. Then, a restart key is displayed in the vicinity of the document display data displayed on the LCD display unit 101. At this time, the display control unit 204 is in the vicinity of a display to remove the jammed document by the automatic document feeder 13 and reset the document, and display data of the document to be read first among the reset documents. The display prompts the user to operate the start key. (S213).

  If it is determined in S210 that there is no incomplete image data or the incomplete image data is equal to or smaller than a predetermined size, the process proceeds to S213 without storing the incomplete image data. In step S213, the display control unit 204 instructs the display data generation unit 203 to generate blank display data and display images for two pages immediately before the original corresponding to the last image. As shown in the figure, the blank image data for display generated on the LCD display unit 101 and the display data for two pages immediately before the interruption are displayed. In FIG. 6, as an example of the display form, a blank image, the first page immediately before, and the second page immediately before are displayed in order from the left. At this time, the display control unit 204 is in the vicinity of a display to remove the jammed document by the automatic document feeder 13 and reset the document, and display data of the document to be read first among the reset documents. The display prompts the user to operate the start key.

  Then, when the user sets a document from the beginning according to the above instruction (S215) and operates one of the first to third start keys, the transmission job is resumed. When the first start key (the leftmost start key in FIGS. 5 and 6) is pressed in step S216, the recovery control unit 208 determines that the document corresponding to the incomplete image has been selected. Since the original corresponding to the incomplete image has not been read, the original reading is resumed without skipping the original in order to read the selected image after the original. If there is no incomplete image, the recovery control means 208 determines that a blank image has been selected. Since there is no original corresponding to the blank image, the original that has not been conveyed when the original conveyance is interrupted is read by restarting the original reading without skipping the original.

  When the center start key is operated in FIGS. 5 and 6, the process proceeds to S217. Here, the incomplete image or the first page of the document immediately before the document conveyance is interrupted is selected. These images have already been read and no longer need to be read. Accordingly, one original is fed blank (S218), and if there is no original corresponding to an incomplete image or an incomplete original, reading is resumed from the original that was scheduled to be read at the time of interruption.

  If the rightmost start key is operated in FIGS. 5 and 6, the process proceeds to S219. Here, the incomplete image or the original of the second page immediately before the interruption of the original conveyance is selected. These images have already been read and no longer need to be read. The same applies to the document on the next page. Accordingly, two originals are fed blank (S220), and if there is no original corresponding to an incomplete image or an incomplete original, reading is resumed from the original that was scheduled to be read at the time of interruption.

  When the transmission job is resumed, the process proceeds to S204, the remaining originals are read (S204 to S208), printing on these originals is executed, and the recovery ends (S209). Note that the processing after S216 is controlled by the recovery control means 208.

  In the above embodiment, the start key displayed on the LCD display unit 101 is operated to select the first transported document among the reset originals. However, one of the displayed display data is operated. You may make it (FIG. 7, FIG. 8). In this case, since the display of the start key can be omitted, the present invention can be implemented with a smaller display space.

  In the above embodiment, the display data is displayed on the LCD display unit 101 as the operation display means, but another display means may be used.

  In the present invention, the display data to be displayed on the LCD display unit 101 may be any document stored in the image storage unit 14, but the incomplete image or the last image and the immediately preceding two as in the above embodiment. A page is preferable. By displaying in this way, the probability that the display data is displayed is increased even when the original after the interruption of the original conveyance is appropriately reset, and the transmission job can be reliably restarted. . In addition, it is possible to make a selectable document clearer by prohibiting selection of a blank image display.

  In the above-described embodiment, the case where transmission is started after reading a series of originals has been described. However, transmission may be performed every time one page of originals is read. In this case, in S203, the transmission control unit 201 connects the electric communication line to enable communication with the transmission destination. Then, the step of S209 may be inserted after S207. Furthermore, when the transmission job is resumed after the document conveyance is interrupted, the image data corresponding to the document on the first page may be transmitted again. Further, when the document conveyance is interrupted, the telecommunication line may be temporarily disconnected and reconnected when the transmission job is resumed.

  As described above, according to the present invention, even when a jam or the like occurs in the automatic document feeder, it can be efficiently recovered. Further, even when a jam or the like occurs in the automatic document feeder and is interrupted, it is easy to confirm the copy corresponding to the jammed document after recovery, and the user's anxiety can be resolved.
