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 users.

  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 goal is to make sure that the user has no missing pages.

  In order to achieve the above object, a first image transmission apparatus according to the present invention is an image transmission apparatus that executes a transmission job for transmitting image data corresponding to a series of originals, and sets conditions for the transmission job. Operation display means, a document feeding / conveying means for feeding the series of documents set on the document stacking means according to the condition setting one by one and sequentially conveying them to the document reading position, and a document at the 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 a plurality of image data stored in the image storage means for the condition setting Transmission control means for transmitting in accordance with the document feeding and conveying means when there is a cause to interrupt conveyance when conveying the series of documents, Incomplete image data storage control means for storing incomplete image data less than one page corresponding to a document page in the middle of copying in the image storage means without erasing, and image data stored in the image storage means Display data generation means for generating display data from the display data.

  According to a second image transmission device of the present invention, in the first image transmission device, the display data generated by the display data generation means is generated from the incomplete image data when conveyance of the series of documents is interrupted. Incomplete image display control means for displaying on the operation display means is provided.

  According to a third image transmission apparatus of the present invention, in the first or second image transmission apparatus, when conveyance of the series of documents is interrupted, there is no incomplete image data, or the incomplete image data has a predetermined capacity. In the following cases, it has a final image display control means for displaying the display data generated by the display data generation means from the image data of the last read document on the operation display means. .

  According to a fourth image transmission apparatus of the present invention, in the second image transmission apparatus, a document of a page corresponding to an incomplete image displayed on the operation display unit and a document of a subsequent page are stored in the document stacking unit. The first recovery display means for displaying on the operation display means a message for prompting the operator to instruct transmission resumption, and when the transmission resumption is instructed, it corresponds to the incomplete image data The first recovery control means for executing the transmission job in accordance with the above condition setting as reading resumed from the document of the page.

  According to a fifth image transmission apparatus of the present invention, in the third image transmission apparatus, a document of a page corresponding to the last image displayed on the operation display unit and a document of a subsequent page are stored in the document stacking unit. A second recovery display means for displaying on the operation display means a message for prompting the operator to instruct transmission resumption, and when transmission resumption is instructed, the second page after the transmission resumption instruction And a second recovery control means for executing the transmission job in accordance with the condition setting, assuming that the image data of the document read thereafter is subsequent to the image data of the last read document. .

  According to a sixth image transmission apparatus of the present invention, in the second image transmission apparatus, a message for prompting an operator to set all of the series of documents on the document stacking unit and instruct to resume transmission is provided. When the third recovery display means displayed on the operation display means and the transmission restart instruction are given, the image data of the original read after the page corresponding to the incomplete image is read from the page corresponding to the incomplete image. In addition, as a continuation of the image data of the document read one page before, there is provided a third recovery control means for executing the transmission job in accordance with the condition setting.

  According to a seventh image transmission apparatus of the present invention, in the third image transmission apparatus, a message for prompting an operator to set all of the series of documents on the document stacking unit and instruct to resume transmission is provided. When the fourth recovery display means displayed on the operation display means and transmission restart are instructed, the image data of the original read one page after the page corresponding to the last image displayed on the operation display means And a fourth recovery control means for executing the transmission job in accordance with the condition setting as following the image data of the last read original.

  According to an eighth image transmission apparatus of the present invention, in the fourth, fifth, sixth, or seventh image transmission apparatus, the transmission control means is stored in the image storage means after the instruction to resume transmission. The image data 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 that feeds and sequentially conveys to the document reading position, document reading means that reads the document at the reading position according to the condition setting, and sequentially stores image data of the read document in page units according to the condition setting Image storage means for transmitting, a transmission control means for transmitting a plurality of image data stored in the image storage means in accordance with the condition setting, and conveying when the document feeding and conveying means conveys the series of documents. If there is a cause of interruption, incomplete image data that is less than one page corresponding to the original page being scanned is deleted. And an incomplete image data storage control means for not stored in the image storage means and thereby functions as a display data generation means for generating display data from the image data stored in said image storage means.

  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, when the first image transmitting apparatus of the present invention is used, an incomplete image of a page in the middle of reading a document that has been erased and discarded in the past when a cause such as jamming of the document interrupts document conveyance occurs. Since data can be saved and display data can be generated from the image data, information for notifying the operator of the original document that actually caused the interruption can be obtained.

  According to the second image transmission apparatus, since the display data corresponding to the original that was being read at the time of the interruption is displayed, it is possible to visually notify the operator of the original 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.

  According to the third image transmission apparatus, if there is no incomplete image data, or if there is only a capacity that cannot determine which page of the document corresponds to the incomplete image data, Instead, since the display data corresponding to the last correctly read original is displayed, it is possible to indirectly notify the operator of the original 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.

  According to the fourth image transmission device, the transmission job can be recovered by resetting from the same original as the original image displayed on the display unit in accordance with the message for prompting the setting of the original, so the transmission is resumed. Can be used without any confusion for the user. In addition, it is possible to check whether a jammed document or the document before and after it has been transmitted correctly after a series of documents has been transmitted in the recovery operation after instructing to resume transmission. There is also an effect of relieving the user's anxiety. Further, since the recovery operation is performed by resetting from the original of the page corresponding to the incomplete image, the job can be completed more quickly than when the original is set from the beginning and the recovery operation is executed.

  According to the fifth image transmission apparatus, the transmission job is recovered by resetting from the same original as the original image displayed on the display unit in accordance with a message prompting the user to set the original. Can be used without any confusion for the user. In addition, it is possible to check whether a jammed document or the document before and after it has been transmitted correctly after a series of documents has been transmitted in the recovery operation after instructing to resume transmission. There is also an effect of relieving the user's anxiety. Further, since the recovery operation is performed by resetting from the original of the page corresponding to the last image, the job can be completed more quickly than when the original is set from the beginning and the recovery operation is executed.

  According to the sixth image transmitting apparatus, the recovery operation time itself is the same as the conventional one, but after transmission by the recovery operation is finished, if a page near the original corresponding to the displayed incomplete image is viewed, It is possible to check whether there are missing pages or duplicated output, and the user's anxiety can be resolved.

  According to the seventh image transmission device, if the page near the document corresponding to the last image displayed is the same as in the case of the sixth image transmission device, the page is missing or is not output redundantly. Can be confirmed, and the user's anxiety can be resolved.

  According to the eighth image transmission device, even if the connection with the transmission destination is disconnected until the cause of the interruption of the document conveyance is removed and the document is set again and an instruction to resume transmission is issued, one page It is transmitted again from the image data of the original of the eye. As a result, the image data from the intermediate page is received at the transmission destination, so that it is not possible to know who has been sent what.

  According to the control program of the present invention, in the past, incomplete image data of a page in the middle of reading a document that has been erased and discarded when a cause of interrupting document conveyance such as a document jam occurs, Since display data can be generated from the image data, it is possible to obtain information for notifying the operator of the original document that actually caused the interruption.

  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 one sheet at a time by the automatic document conveying device 13 or illuminates a document placed on a contact glass with a halogen lamp or a fluorescent lamp and reads the reflected light with a CCD sensor. An analog signal is converted into a digital signal by A / D conversion, image processing is performed by the image processing unit, and the image is expanded in the subsequent bitmap memory 15. In the copy function, the image expanded in the bitmap memory 15 is converted by the CODEC 16. It is encoded 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 unit 14 encodes and stores the image data read by the scanner unit 12 with the CODEC 16 when performing normal facsimile memory transmission and reservation 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 is encoded and stored by the CODEC 16, and can be transmitted to an external PC (24, 25) personal computer. Then, 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 forming apparatus is often used as an image memory by 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.

  In particular, in the image transmission apparatus of the present invention, as shown in FIG. 10, the CPU 2 includes a transmission control unit 201, an incomplete image data storage control unit 202, a display data generation unit 203, an incomplete image display control unit 204, a first Recovery display means 205, first recovery control means 206, last image display control means 209, second recovery display means 210, and second recovery control means 211. Further, instead of the first recovery display unit 205, the first recovery control unit 206, the second recovery display unit 210, and the second recovery control unit 211, a third recovery display unit 207, a third recovery A control unit 208, a fourth recovery display unit 212, and a fourth recovery control unit 213 may be provided. Needless to say, the CPU 2 controls not only the operations of the respective means 204 to 213 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.

  When the document conveyance is interrupted, the incomplete image display control unit 204 selects the incomplete image data and instructs the display data generation unit 203 to generate display data from the incomplete image data. Further, the generated display data is displayed on the LCD display unit 101 of the operation panel 10.

  The last image display control unit 209 selects the image data of the last read document when the document conveyance is interrupted, when there is no incomplete image data, or when the incomplete image data is less than a predetermined capacity, The display data generation unit 203 is instructed to generate display data from the last image data. Further, the generated display data is displayed on the LCD display unit 101 of the operation panel 10.

  When the display data is displayed by the incomplete image display control unit 204, the first recovery display unit 205 displays the original of the page corresponding to the page corresponding to the incomplete image and the original of the subsequent pages. A message for prompting the operator to set on the document stacking tray 27 and instruct to resume transmission is displayed on the LCD display unit 101. Note that the timing for displaying this message is after the cause of interrupting the document conveyance is removed, for example, after the jam is cleared, the cover is closed, and the power is turned on.

  When the first recovery control unit 206 is instructed to resume transmission, the first recovery control unit 206 assumes that reading of the page corresponding to the incomplete image data has been resumed, starts reading the document, and executes the transmission job according to the above condition setting. To do. Here, if image data stored in the image storage unit 14 before resuming the transmission job has not been transmitted yet, transmission can 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, so transmission starts from the image data of the original read after the instruction to resume transmission. Will do. 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, the first recovery display means 205 displays the display data for the page corresponding to the incomplete image and the above message, so if the operator sets the document according to the display, the document conveyance is interrupted. Reading is resumed from the original page of the page that caused the problem.

  When the display data is displayed by the last image display control means 209, the second recovery display means 210 displays the original of the page corresponding to the last image displayed on the display unit and the subsequent pages. A document is set on the document stacking tray 27, and a message for prompting the operator to instruct transmission restart is displayed on the LCD display unit 101. Note that the timing for displaying this message is the same as that by the first recovery display means 205.

  When the second recovery control means 211 is instructed to resume transmission, the image data of the document read after the second page after the instruction to resume transmission is followed by the image data of the last read document. Execute the send job according to the condition settings. Here, if image data stored in the image storage unit 14 before resuming the transmission job has not been transmitted yet, transmission can 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. Therefore, transmission is performed from the image data of the second and subsequent pages after the instruction to resume transmission. Will start. 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, the display data for the page corresponding to the incomplete image and the above message are displayed by the second recovery display means. If the operator sets the document according to the display, it causes interruption of the document conveyance. Scanning is resumed from the original page. Then, since the second recovery control unit 211 recognizes the first transported document as the document of the page corresponding to the last image after the transmission job is resumed, the image data of the document read from the second page onward Are added to the image storage means 14, so that a series of copies of the original is normally completed. Note that for the first document transported after resuming the transmission job, either delete the image data obtained by scanning the image, or replace it with the last scanned image data stored before resuming the transmission job. However, it is preferable to feed the image without reading it.

  The third recovery display means 207 operates to instruct to resume transmission by setting all of the series of originals on the original stacking means when display data is displayed by the incomplete image display control means 204. A message for prompting the user is displayed on the LCD display unit 101. Note that the timing for displaying this message is the same as that by the first recovery display means 205.

  The third recovery control unit 208, when instructed to resume transmission, causes the image data of the original read after the page corresponding to the incomplete image to be one page before the page corresponding to the incomplete image. The transmission control unit 201 is instructed to execute transmission according to the condition setting following the image data of the read original. 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, the above message is displayed by the third recovery display means. If the operator sets a series of originals according to the display, reading is resumed from the original of the page that caused the interruption of the original conveyance. It will be. For a document up to one page before the page corresponding to the incomplete image after resuming the transmission job, the image data obtained by reading the image is deleted, or the corresponding page stored before the transmission job is resumed. Although it can be replaced with image data, it is preferable to skip the image without reading it.

  The fourth recovery display means 212 is an operation for setting all of a series of originals on the original stacking means and instructing transmission resumption when display data is displayed by the last image display control means 209. A message for prompting the user is displayed on the LCD display unit 101. Note that the timing for displaying this message is the same as that by the first recovery display means 205.

  The fourth recovery control unit 213, when instructed to resume transmission, reads the image data of the document read one page after the page corresponding to the last image displayed on the display unit at the end. The transmission control unit 201 is instructed to execute transmission in accordance with the condition setting following the image data of the original document. Here, if there is image data stored in the image storage unit 14 before the transmission job is resumed, transmission is 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. Therefore, after the instruction for resuming transmission, it is 1 more than the page corresponding to the last image. Transmission is started from the image data of the original read after the page. 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, the above message is displayed by the third recovery display means. If the operator sets a series of originals according to the display, reading is resumed from the original of the page that caused the interruption of the original conveyance. Will be. For a document up to the page corresponding to the last image after the transmission job is resumed, the image data obtained by reading the image is erased or replaced with the image data of the corresponding page stored before the transmission job is resumed. Although it is possible, it is preferable to feed the image without reading it.

  As a first embodiment of the present invention, a process related to recovery when transmitting image data corresponding to a series of originals 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 (S101), a series of documents is set on the document stacking means 27 of the automatic document feeder 13 (S102), and the start key 102 is operated (S103). While feeding one sheet (S104), 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 (S105). At this time, it is determined whether or not a jam or the like has been interrupted in the automatic document feeder 13 (S106). If there is no jam, it is determined whether or not all the documents on this page have been read (S107). If not, the process returns to S106. If the reading of this page is completed, it is determined whether or not there is a document for the next page (S108). If there is, the process returns to S104. 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 S101. 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 completed (S109).

  In S109, the flow is such that transmission is started after all the originals have been read. However, in the case of direct transmission in the facsimile apparatus, pages that have 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 S106, the incomplete image data storage control unit 202 determines whether there is incomplete image data read halfway through the page of the document (S110), 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 (S111). 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. (S112). 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 incomplete image display control unit 204 instructs the display data generation unit 203 to generate incomplete image data for display generated from the incomplete image data, as shown in FIG. The incomplete image data for display generated on the display unit 101 is displayed. At this time, the first recovery display means 205 displays an indication that the original jammed by the automatic document feeder 13 is to be removed and “Reset from the same original as this original image and restart.” Display is performed to prompt the user to set again from the same original as the original of the incomplete image (S113). When the user sets the same original as the incomplete image and the subsequent original according to the instruction (S114) and operates the start key (S115), the process proceeds to S104 and the job resumes from the original jammed by the first recovery control means 206 As a result, the reading of the document is started, the transmission job is executed according to the above condition setting, and recovery is performed.

  If it is determined in S110 that there is no incomplete image data, the process proceeds to S117 without storing the incomplete image data. If the incomplete image data is equal to or smaller than the predetermined size in S111, this incomplete image data is stored. Is stored in the image storage means 14 without being erased (S116), and the process proceeds to S117. In S116, even a small amount of incomplete image data is stored because it may be useful if displayed, but it is not particularly necessary to store it. In S117, the last image display control means 209 instructs the display data generation means 203 to display the last image data for display generated from the last read image data, and the LCD as shown in FIG. Display data generated on the display unit 101 is displayed (in this embodiment, incomplete image data is also displayed in parallel). At this time, the second recovery display means displays that the automatic document feeder 13 removes the jammed document, and displays “Reset from the same document as the left document image and restart.” To prompt the user to set again from the same original as the last read original. When the user sets the same original as the last read image and the original after that according to the instruction (S118) and operates the start key (S119), the second recovery control unit 211 has already read the last read original as image data. Therefore, the image data of the original read next is transferred to the image data of the original read next to the image data of the original read last, and the transmission job is executed according to the condition setting. Execute and recover.

  In this first embodiment, incomplete image data smaller than a predetermined size is displayed in parallel, but when this is not displayed, it may be display of incomplete image data or display of the last read image. However, in any case, there is no problem because the document is recovered if it is set from the same document as the displayed document.

  As a second embodiment of the present invention, processing related to recovery when copying a series of documents over a plurality of pages will be described with reference to the flowchart of FIG. In FIG. 7, the processing flow from S201 to S209 is the same as the processing flow from S201 to S209 in the first embodiment, so the description thereof will be omitted, and the processing will be described from the processing when a jam or the like is interrupted in S206. And

  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). Subsequently, the incomplete image display control means 204 instructs the display data generation means 203 to display the incomplete image data for display generated from the incomplete image data, as shown in FIG. The incomplete image data for display generated on the LCD display unit 101 is displayed. At this time, the third recovery display means 207 displays a message that the document jammed by the automatic document feeder 13 is to be removed and a message “Please reset the document from the beginning and restart it”. The user is prompted to reset the original from the beginning (S213).

  If it is determined in S210 that there is no incomplete image data, the process proceeds to S215 without storing the incomplete image data. If the incomplete image data is equal to or smaller than the predetermined size in S211, this incomplete image data is stored. Is stored in the image storage means 14 without being erased (S214), and the process proceeds to S215. In S214, even a small amount of incomplete image data is stored because it may be useful if it is displayed, but it is not particularly necessary to store it. In S215, the last image display control unit 209 instructs the display data generation unit 203 to display the last image data for display generated from the last read image data, and the LCD as shown in FIG. Display data generated on the display unit 101 is displayed (in this embodiment, incomplete image data is also displayed in parallel). At this time, the fourth recovery display means 212 displays a message to remove the jammed document by the automatic document feeder 13 and a message “Please reset the document from the beginning and start again.” Prompt the user to reset the document from the beginning.

  When the user sets a document from the beginning according to the above instruction (S216) and operates the start key (S217), the re-set one document is fed (S218), and the image data corresponding to this document has already been stored. If so (S219), the document is conveyed and discharged without being read (S220), and the process returns to S218 to feed the next document. If there is no corresponding image data in S219, the process proceeds to S204 for recovery. If S212 and S213 are passed, the third recovery control means 208 controls the processing after S218. If S215 is passed, the fourth recovery control means 213 controls the processing after S218.

  In the second embodiment, the incomplete image or the last image is displayed as soon as a jam occurs, but may be displayed when the job is finished. Further, the effect of the present invention can be obtained even if the processing is to be displayed as necessary.

  As described above, according to the first embodiment, even when a jam or the like occurs in the automatic document feeder, the recovery can be performed efficiently. In addition, according to the second embodiment, even when a jam or the like occurs in the automatic document feeder and is interrupted, it is possible to easily confirm the copy corresponding to the jammed document after the recovery, Resolve user anxiety.

  In the first and second embodiments, 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 S103 and S203, the transmission control unit 201 connects the electric communication line so that communication with the transmission destination is possible. Then, the steps of S109 and S209 may be inserted after S107 and 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.
