[First Embodiment]
Hereinafter, a first embodiment of an image reading apparatus of the present invention will be described in detail with reference to the drawings. In the present embodiment, an example in which the present invention is applied to a multifunction machine including an image reading device will be described.

  As shown in FIG. 1, a multifunction machine 10 according to the present embodiment includes a controller unit 12, a user interface (U / I) 14, an image reading device 16, a printing unit 18, a FAX unit 20, and a network. And an interface 22.

  The controller unit 12 includes a ROM (Read Only Memory) 12a, an HDD (Hard Disk Drive) 12b, a CPU (Central Processing Unit) 12c, a RAM (Random Access Memory) 12d, an NV (Nonvolatile Memory) 12e, and an I / O (input). An output) port 12f is provided. The ROM 12a, HDD 12b, CPU 12c, RAM 12d, NV 12e, and I / O port 12f are connected to each other via a bus 12g.

  A basic program such as an OS is stored in the ROM 12a as a storage medium.

  The HDD 12b as a storage medium has various programs for executing processing routines of control processing, printing processing, first copying processing, image data storage processing, and reading end notification storage processing, which will be described in detail below. Is remembered. The HDD 12b stores a read prohibition release authority registration table 24 shown in FIG. As shown in the figure, a record 26 is registered in the reading prohibition release authority registration table 24 for each user ID of the user who operates the multifunction machine 10. Each record 26 includes a field 28 in which a user ID corresponding to each user is registered, and a user corresponding to the user ID registered in the field 28 prohibits reading of an image to which reading prohibition information described later is added. If you have the authority to release, "permitted" to indicate that you have this authority, while if you do not have authority, "not permitted" to indicate that you do not have this authority "Is registered. Each record 26 is registered in advance by the administrator of the multifunction machine 10 or the like via the U / I 14.

  The CPU 12c reads the program from the ROM 12a and the HDD 12b and executes it.

  Various data are temporarily stored in the RAM 12d.

  The NV 12e is a non-volatile memory. The NV 12e stores setting information that is not to be erased even when a switch (not shown) of the multifunction machine 10 is turned off and the power is turned off. In the present embodiment, for example, copy processing mode information 32 that is a 1-bit flag as shown in FIG. 2B is stored in the NV 12e. In the copy processing mode information 32, a predetermined value, for example, “1”, for example, “1” is set by the administrator of the multifunction device 10 when the first copy processing is executed. In addition, a predetermined value, for example, “0” is set in the mode in which the normal copying process is performed.

  A U / I 14, an image reading device 16, a printing unit 18, a FAX unit 20, and a network interface 22 are connected to the I / O port 12f.

  The U / I 14 includes a display device including a touch panel that receives an instruction from a user and an LCD that performs display based on input information.

  The image reading device 16 outputs image data obtained by sequentially reading a document sheet as an image forming medium for each predetermined area. Further, the image reading device 16 extracts the read prohibition information and information similar to the read prohibition information from the obtained image data. As shown in FIGS. 3A and 3B, the image reading device 16 includes a document table 34, a document sensor 36, a sheet transport unit 38, a platen glass 40, a light source 42, a CCD (Charge Coupled Device) 44, The document passage sensor 46, the control unit 48, the image processing unit 50, and an I / F (interface) 52 connected to the I / O port 12 f of the controller unit 12 are provided.

  A plurality of document sheets 56 of a document 54 to be read are placed on the document table 34.

  The document sensor 36 includes, for example, an optical sensor, and is disposed at a position where the document sheet 56 placed on the document table 34 can be detected. Therefore, when the document sheet 56 is placed on the document table 34, the document sensor 36 detects the document sheet 56 and outputs an ON state detection signal, and also places the document sheet 56 on the document table 34. If not, an off state detection signal is output. The document sensor 36 is also connected to the I / O port 12f.

  The paper transport unit 38 includes a drawing roller 38a and a transport roller 38b. The original paper 56 placed on the original table 34 is drawn one by one by the drawing roller 38a. Further, the original paper 56 is conveyed by the conveying roller 38b so that a predetermined area of the original paper 56 passes through the reading position of the CCD 44. As a result, the predetermined area of the drawn original paper 56 can be read by the CCD 44. Further, the original paper 56 is conveyed by the conveying roller 38 b so that the original paper 56 having a predetermined area of the original paper 56 read by the CCD 44 is discharged to the original discharge portion 54.

  The document passage sensor 46 includes, for example, an optical sensor, and is disposed at a position where the document sheet 56 conveyed by the conveyance roller 38b of the sheet conveyance unit 38 can be detected. Therefore, the original passage sensor 46 detects the original paper 56 when the original paper 56 exists at the reading position and outputs an on-state detection signal, and turns off when the original paper 56 does not exist. A state detection signal is output. The document passage sensor 46 is also connected to the I / O port 12f.

  The CCD 44 converts the light reflected from the light source 42 by the transported original paper 56 into an electric signal and outputs it to the image processing unit 50.

  The image processing unit 50 converts the electrical signal output from the CCD 44 into image data, performs predetermined processing on the image data, such as density adjustment and removal of noise caused by the color of the original paper 56, and the like. The image data subjected to the above process is output to the controller unit 12 via the I / F 52. Further, the image processing unit 50 analyzes the image data to determine whether or not the additional information added to the image data includes read prohibition information, and determines that the read prohibition information is included. If the read prohibition information is extracted from the image data, the read prohibition information is included in the read end notification information indicating that the reading of the formation information formed on the original paper 56 has been completed. 12 is output. When the image processing unit 50 analyzes the image data and extracts the read prohibition information from the image data, the image processing unit 50 may extract information similar to the read prohibition information instead of the read prohibition information as the read prohibition information. is there. There are various causes for this phenomenon. One of the causes is that the analysis accuracy is low.

  The control unit 48 controls each of the document sensor 36, the sheet conveyance unit 38, the light source 42, the CCD 44, the document passage sensor 46, the image processing unit 50, and the I / F 52.

  The printing unit 18 forms an image based on the input image data and outputs it as an output product.

  The FAX unit 20 has a facsimile function, and transmits image data via the telephone line 58 and receives image data from the transmission source via the telephone line 58.

  An external terminal PC (Personal computer) 62 is connected to the network interface 22 via a network 60. The user can operate the PC 62 to output a predetermined instruction to the multifunction machine 10 via the network 60. For example, when image data is transmitted from the PC 62 to the multifunction device 10 and a print execution instruction is output, an original paper on which an image based on the image data is formed is output from the multifunction device 10.

  Next, a processing routine of control processing executed by the CPU 12c of the controller unit 12 of the multifunction machine 10 will be described with reference to FIG. In the present embodiment, this control process is executed every predetermined time interval (for example, several tens of milliseconds) from the time when a switch (not shown) of the multifunction machine 10 is turned on.

  First, in step 100, it is determined whether an instruction from the PC 62 or the U / I 14 has been received. In the present embodiment, a printing process instruction for performing a printing process can be input from the PC 62 and the U / I 14, and a copying process instruction for performing a copying process can be input from the U / I 14.

  If it is determined in step 100 that an instruction has been received, it is determined in next step 102 whether the received instruction is a print processing instruction or a copy processing instruction.

  If it is determined in step 102 that the instruction is a print processing instruction, in the next step 104, print processing, which will be described in detail later, is executed. Then, this control process ends.

  On the other hand, if it is determined in step 102 that the instruction is a copy process instruction, in the next step 106, the copy process mode information 32 is acquired by reading the copy process mode information 32 stored in the NV 12e.

  In the next step 108, it is determined whether or not the value set in the copy processing mode information 32 is a value representing a mode for performing normal copy processing, for example, “0”.

  If it is determined in step 108 that the value set in the copy processing mode information 32 is a value representing a mode in which normal copy processing is performed, the process proceeds to the following step 110 and step 112, and normal copy is performed. Processing is performed. That is, in step 110, an instruction to read all the document sheets 56 placed on the document table 34 is output to the image reading device 16. As a result, the image data is output from the image reading device 16 to the controller unit 12. On the other hand, when the image data is received, the CPU 12c of the controller unit 12 executes an image data storage process as an interrupt process that causes the reception of the image data to start execution. Here, the processing routine of the image data storage process will be described with reference to FIG. 5A. First, in step 200, the received image data is stored in the HDD 12b. Then, the main image data storage process ends. As described above, the image data output process from the image reading device 16 is stored in the HDD 12b by executing the image data storing process as the interrupt process after the process in the step 110. In step 112, the image data stored in the HDD 12 b is read and the read image data is output to the printing unit 18. As a result, an output product on which an image based on the image data is formed (that is, a sheet on which the image is formed) is output from the printing unit 18.

  On the other hand, if it is determined in step 108 that the value set in the copy processing mode information 32 is not a value representing a mode for performing normal copy processing, the value set in the copy processing mode information 32 is the first value. It is determined that the value represents a mode for executing one copy process, for example, “1”, and the process proceeds to the next step 114.

  In step 114, a first copying process, the details of which will be described later, is executed. Then, this control process ends.

  Next, details of the processing routine of the printing process in step 104 will be described with reference to FIG.

  First, in step 300, it is determined whether or not read prohibition information indicating read prohibition is received together with a print processing instruction.

  If it is determined in step 300 that the read prohibition information has not been received, in the next step 308, the image data received together with the print processing instruction and stored by the image data storage process is read from the HDD 12b. The read image data is output to the printing unit 18. As a result, as shown in FIG. 7A, the printing unit 18 outputs an output 57 in which an image 64 based on the image data (“ah” in the example of FIG. 7A) is formed. . When a part of the image 64 is a similar image similar to an image representing the read prohibition information, the read prohibition information is erroneously extracted when the read prohibition information is extracted. There is a case. Then, the printing process ends. The output 57 output from the printing unit 18 can be the original paper 56 of the original 54 placed on the original table 34 as a copy target.

  On the other hand, if it is determined in step 300 that read prohibition information has been received, in the next step 302, image data representing read prohibition information, that is, read prohibition information indicating read prohibition when analyzed is added information. The image data extracted as is generated.

  In the next step 304, the image data received together with the print processing instruction and stored by the image data storage process is read from the HDD 12b, and the read image data and the image data generated in step 302 are combined.

  In the next step 306, the image data synthesized in step 304 is output to the printing unit 18. Thereby, as shown in FIG. 7B, an image 64 (“Ah” in the example of FIG. 7B) 64 based on the image data read out in step 304 is formed from the printing unit 18. At the same time, an output product 57 on which an image 66 based on the additional information representing the read prohibition information is formed is output. As described above, when a part of the image 64 is a similar image similar to the image representing the read prohibition information due to various causes, extraction of the read prohibition information for prohibiting the reading is performed. If it is performed, it may be erroneously extracted as read prohibition information. Then, the printing process ends.

  Next, details of the processing routine of the first copying process in step 114 will be described with reference to FIG. The first copying process is an example of the copying process when the automatic document feeding function is used.

  First, in step 400, the value of the variable N is set to 1, and in the next step 402, it is determined whether or not the detection signal from the document sensor 36 is in an on state, whereby the document 54 is placed on the document table 34. It is determined whether or not the original paper 56 is placed. Note that, as described above, only the image 64 is formed on the original paper 56 placed on the original platen 34 as shown in FIG. 7A, or FIG. In some cases, an image 64 and an image 66 as additional information are formed as shown in FIG.

  If it is determined in step 402 that the detection signal is on, it is determined that the document sheet 56 is placed on the document table 34, and the Nth document sheet 56 is loaded in the next step 404. An instruction for reading the Nth original sheet 56 is output to the image reading device 16 so as to read it. In response to this instruction, the image reading device 16 reads the Nth original paper 56 and outputs the image data to the controller unit 12. As described above, when receiving the image data, the controller unit 12 executes an image data storage process and stores the received image data in the HDD 12b. Further, as described above, the image reading device 16 analyzes the image data to determine whether or not the additional information added to the image data includes the read prohibition information. When it is determined that the image data is included, the reading prohibition information is extracted from the image data, and is extracted into the reading end notification information indicating that the reading of the formation information formed on the Nth original sheet 56 is finished. The read prohibition information is included and output to the controller unit 12. On the other hand, when the CPU 12c of the controller unit 12 receives the reading end notification information, the CPU 12c executes a reading end notification storing process as an interrupt process that causes the reception start of the reading end notification information. Here, the processing routine of the reading end notification storing process will be described with reference to FIG. 5B. First, in step 500, the received reading end notification information is stored in the HDD 12b. Then, the reading completion notification storage process is terminated. As described above, after the process in step 404, the reading end notification storage process which is an interruption process is executed, whereby the reading end notification information output from the image reading device 16 is stored in the HDD 12b.

  In the next step 406, it is determined whether or not the reading completion notification of the Nth original sheet 56 has been received and stored by the reading completion notification storing process.

  If it is determined in step 406 that the reading completion notification of the Nth original paper 56 has been received and stored by the reading completion notification storage process, the process proceeds to the next step 408.

  In step 408, it is determined whether or not read prohibition information is included in the received read end notification information.

  If it is determined in step 408 that the reading prohibition information is not included in the reading completion notification information, the Nth image data stored in the HDD 12b is output to the printing unit 18 in the next step 420. As a result, an output product on which an image based on the Nth image data is formed is output from the printing unit 18.

  In the next step 422, the value of the variable N is incremented by 1, and the process returns to step 402.

  On the other hand, if it is determined in step 408 that the reading prohibition information includes the reading prohibition information, it is determined that reading of the original paper 56 needs to be stopped, and the process proceeds to the next step 410.

  In step 410, the reading prohibition release authority registration table 24 stored in the HDD 12b is read, and the record 26 in the field 28 in which the user ID input by the user is registered together with the copy processing instruction is specified. Then, the read prohibition release authority registered in the field 30 of the specified record 26 is acquired.

  In the next step 412, whether or not the user who issued the copy processing instruction has the authority to cancel the reading prohibition by determining whether or not the reading prohibition canceling authority acquired in step 410 indicates “permitted”. Determine whether.

  If it is determined in step 412 that the read prohibition release authority does not indicate “permitted”, it is determined that the user does not have the authority to cancel the read prohibition, and the next step 428 cancels the job. Do. Here, the job cancel is regarded as having not been given the current copy processing instruction, and is copied from the printing unit 18 by discarding all the image data stored in the HDD 12b by the first copy processing executed this time. This can be done by preventing the object from being output.

  In the next step 430, when the process proceeds from step 428 to step 430, the user ID of the user who issued the copy processing instruction and information indicating that the copy processing instruction has been input but job cancellation has been performed are included. A log is generated, and the generated log is stored in the HDD 12b. Then, the first copying process is terminated.

  On the other hand, if it is determined in step 412 that the read prohibition release authority indicates “permitted”, it is determined that the user has the authority to cancel the read prohibition, and in the next step 414, N sheets are read. A reading prohibition release button for accepting a resumption instruction to resume reading that has been canceled on the original paper 56 up to the eye, discarding the Nth image data stored in the HDD 12b, and up to the Nth original paper 56. A skip button for accepting a skip instruction for resuming reading that has been canceled in 56, image data stored in the HDD 12b by the first copy process executed this time, assuming that there was no copy process instruction this time. By canceling all of these, a job cancel instruction for accepting a job cancel instruction for preventing a copy from being output from the printing unit 18 is displayed. Controlling the display of U / I14 as cell button, and a message for prompting the user to select these buttons are displayed. As a result, as shown in FIG. 9, a read prohibition release button 68, a job cancel button 70, a skip button 72, and a message 74 are displayed on the U / I 14. In this way, by displaying the read prohibition release button 68 for accepting a resume instruction to resume reading, the user is notified that a resume instruction to resume suspended reading is accepted.

  In the next step 416, any one of the reading prohibition release button 68, the job cancel button 70, and the skip button 72 displayed on the U / I 14 is pressed by the user and is output from the U / I 14. It is determined whether an instruction corresponding to the button has been received.

  If it is determined in step 416 that the instruction has been received, the process proceeds to the next step 418. In step 418, whether the received instruction is a restart instruction for restarting reading that has been stopped on the Nth original paper 56, the Nth image data stored in the HDD 12 b is discarded and N It is determined whether the instruction is a skip instruction for resuming reading that has been canceled on the first original paper 56 or a job cancel instruction.

  If it is determined in step 418 that the instruction is a job cancel instruction, the process proceeds to the next step 428 to perform the processing described above.

  If it is determined in step 418 that the instruction is a restart instruction, the process proceeds to the next step 420. In step 420, the Nth image data stored in the HDD 12 b is output to the printing unit 18.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the present embodiment, an example in which the present invention is applied to a multifunction machine including an image reading device will be described. Further, the same configurations and the same processes as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the present embodiment, a program for executing the processing routine of the second copying process shown in FIG. 10 is stored in the HDD 12b, and a program for executing the processing routine of the high-speed document reading instruction output process shown in FIG. Is stored in the HDD 12b, and the CPU 12c is different from the first embodiment in that the second copying process is executed instead of the first copying process and the high-speed document reading instruction output process is executed.

  The second copying process performed by the CPU 12c of the controller unit 12 of the multifunction machine 10 will be described with reference to FIG. The second copying process is an example of the copying process when the automatic document feeding function is used.

  In the second copying process, if it is determined in step 402 that the detection signal is on, the process proceeds to the next step 600. In step 600, execution of high-speed document reading instruction output processing is started. A processing routine of the high-speed document reading instruction output process will be described with reference to FIG.

  First, in step 700, an instruction for reading the Nth original paper 56 is output to the image reading device 16 so as to read the Nth original paper 56. In response to this instruction, the image reading device 16 reads the Nth original paper 56 and outputs the image data to the controller unit 12. Further, as described above, the image reading device 16 analyzes the image data to determine whether or not the additional information added to the image data includes the read prohibition information. Is determined to be included, the reading prohibition information is extracted from the image data, and the reading end notification information indicating that the reading of the formation information formed on the Nth original sheet 56 is finished is included in the reading end notification information. The extracted read prohibition information is included and output to the controller unit 12. As shown in FIG. 12, the time T1 when the image data is output by the image reading apparatus (N = 1 in the example of FIG. 12) and the N-th reading end notification information are output. It is not the same as the time T2, and the reading end notification information is output after the output of the image data. This is by analyzing the image data and determining whether or not the additional information added to the image data includes the read prohibition information. If it is determined that the read prohibition information is included, the read prohibition information is read prohibited. This is because it takes time to include information. On the other hand, as described above, when receiving the image data, the controller unit 12 executes an image data storage process and stores the received image data in the HDD 12b. Furthermore, when the CPU 12c of the controller unit 12 receives the reading end notification information, as described above, the CPU 12c executes the reading end notification storing process and stores the received reading end notification information in the HDD 12b.

  In the next step 702, it is determined whether or not the state of the detection signal from the document passage sensor 46 has changed from the on state to the off state, so that the document sheet 56 has passed the reading position of the document passage sensor 46; That is, it is determined whether or not the document sheet 56 placed on the document table 34 has been pulled into the sheet transport unit 38 by the pull-in roller 38a.

  If it is determined in step 702 that the on state has changed to the off state, it is determined that the original paper 56 has been drawn into the paper transport unit 38, and in the next step 704, the original of the next page (N + 1 pages). In order to read the formation information of the paper 56, the value of the variable N is incremented by one.

  In the next step 706, it is determined whether or not the document sheet 56 of the document 54 is placed on the document table 34 by determining whether or not the detection signal from the document sensor 36 is in an ON state.

There is. That is, when the controller unit 12 receives the N-th reading end notification information, the K (K ≧ N) -th image data may be received. As described above, this is because the image data is analyzed to determine whether or not the additional information added to the image data includes read prohibition information. This is because it takes time to include the read prohibition information in the read end notification information.

  As described above, in this embodiment, when the N-th reading end notification information is received in step 602, the K-th image data has already been received and stored in the HDD 12b.

  If it is determined in step 418 that the instruction is a restart instruction, the process proceeds to the next step 604. In step 604, the image data from the Nth sheet to the Kth sheet stored in the HDD 12 b is output to the printing unit 18. Thereby, each output based on each image data based on each image data from the Nth sheet to the Kth sheet is output. Then, the process returns to step 402. If it is determined in step 402 that the detection signal is in the ON state, in the next step 600, the high-speed document reading instruction output process is started (resumed) again.

  If it is determined in step 418 that the instruction is a skip instruction, the process proceeds to the next step 606. In step 606, the Nth image data stored in the HDD 12b is discarded.

However, the CPU 12c of the controller unit 12 may extract the read prohibition information from the image data. In this case, the multi-function device 10 sequentially reads a plurality of document sheets 58 on which the image 64 is formed and the read prohibition information 66 for prohibiting the reading of the image 64 is formed as necessary. The image reading device 16 for obtaining the image data, obtains the read release authority 30 indicating whether or not the read prohibition of the image 64 is canceled, and information similar to the read prohibition information and the read prohibition information from the image data. Is read as read prohibition information, and when the read prohibition information is extracted, the image reading device 16 is controlled to stop reading, and when a restart instruction for restarting reading is received, the canceled reading is restarted.

As described above, when receiving the reading end notification information, the controller unit 12 executes a reading end notification storage process and stores the received reading end notification information in the HDD 12b. Then, the process returns to step 902.

  On the other hand, if it is determined in step 906 that the value of the reading flag is not a value indicating a mode for performing reading, it is determined that the value of the reading flag is a mode for not performing reading. Return to 902.

  On the other hand, if it is determined in step 904 that the notification information determined to be received in step 902 is not notification information including information indicating that the original paper 56 of the next page exists, the next step 912 is performed. Thus, it is determined whether or not the notification information determined to be received in step 902 is the reading end notification information.

  If it is determined in step 912 that the received notification information is reading end notification information, the process proceeds to the next step 914. In step 914, it is determined whether or not read prohibition information is included in the received read end notification information. In the present embodiment, the count value (here, the value of the number of sheets) M of the original paper 56 corresponding to the received reading end notification information, for the reason described with reference to FIG. Is not necessarily the same value as the variable N, and may be less than or equal to the variable N.

  If it is determined in step 914 that the reading end notification information includes the reading prohibition information, the process proceeds to the next step 916. In step 916, an instruction for stopping (stopping) reading of the original paper 56 is output to the image reading device 16. Accordingly, the image reading device 16 that has received this instruction stops reading.

  In the next step 918, the value of the reading flag is set to a value indicating a mode for not reading, for example, “1”. Thereby, it becomes a mode for not performing reading.

  In the next step 920, reading is performed because the reading is prohibited by extracting the reading prohibition information as information indicating the factor that the reading by the image reading device 16 is stopped (stopped) in the stop factor file stored in the HDD 12b. A character string indicating the stoppage, for example, “read prohibition detection” is overwritten and written.

  In the next step 922, information indicating the Mth original paper 56, for example, “Mth” is registered in the prohibited original list file stored in the HDD 12b. Then, the process returns to step 902.

  On the other hand, if it is determined at step 914 that the reading prohibition information is not included in the reading end notification information, the process proceeds to the next step 924. In step 924, a stop factor file stored in the HDD 12b is read, and a character string indicating that reading has been stopped because it has been detected by extracting read prohibition information into the stop factor file, for example, “read prohibition detection”. It is determined whether "" is written.

  If it is determined in step 924 that a character string indicating that reading has been stopped because it has been detected by extracting the reading prohibition information has not been written, the process proceeds to the next step 926. In step 926, each image data up to the Mth sheet stored in the HDD 12 b is output to the printing unit 18. Thereby, each output based on each image data based on each image data up to the Mth image is output. Then, the process returns to step 902.

  On the other hand, if it is determined in step 924 that a character string indicating that reading has been stopped because it has been detected by extracting the reading prohibition information has been written, the process returns to step 902.

  On the other hand, if it is determined in step 912 that the received notification information is not the reading completion notification information, the process proceeds to the next step 928. In step 928, it is determined whether or not the received notification information is notification information including information indicating that the original paper 56 of the next page does not exist.

  If it is determined in step 928 that the received notification information is notification information including information indicating that the original paper 56 of the next page does not exist, the process proceeds to the next step 930. In step 930, the stop factor file stored in the HDD 12 is read, and it is determined whether or not information indicating the factor that stopped reading (stopped) by the image reading device 16 is written in the stop factor file. Note that the character string “none” described above is not information indicating a factor in which reading by the image reading device 16 is stopped (stopped).

  If it is determined in step 930 that information indicating the factor that stopped reading (stopped) by the image reading device 16 is not written in the stop factor file, the process proceeds to the next step 932. In step 932, an instruction for stopping (stopping) reading of the original paper 56 is output to the image reading device 16. Accordingly, the image reading device 16 that has received this instruction stops reading.

  In the next step 934, the value of the reading flag is set to a value indicating a mode for not reading, for example, “1”. Thereby, it becomes a mode for not performing reading.

  In the next step 936, the document sheet 56 to be read placed on the document table 34 is stored in the stop factor file stored in the HDD 12 b as information indicating the factor that stopped reading (stopped) by the image reading device 16. A character string indicating that reading has been stopped because it no longer exists (has disappeared), for example, “reading end” is overwritten and written. Then, the process returns to step 902.

  On the other hand, if it is determined in step 930 that the information indicating the factor that stopped reading by the image reading device 16 is written in the stop factor file, the process returns to step 902.

  On the other hand, if it is determined in step 928 that the received notification information is not notification information including information indicating that the original paper 56 of the next page does not exist, reading of the received notification information has been stopped. If it is determined that the notification information includes information indicating that, the process proceeds to the next step 938. In step 938, the stop factor file stored in the HDD 12b is read, and a character string indicating that reading has been stopped because it has been detected by extracting read prohibition information into the stop factor file, for example, “read prohibition detection”. "Or, a character string indicating that reading has been stopped because the original paper 56 to be read placed on the original platen 34 no longer exists (has disappeared), for example," reading end "is written. Judge whether there is.

  In step 938, if a character string indicating that reading has been stopped because the document paper 56 to be read placed on the document table 34 no longer exists (is lost) is written in the stop factor file. If it is determined, in the next step 940, whether or not the image data up to the Nth sheet has been output to the printing unit 18 and whether or not the image data up to the Nth sheet has been output to the printing unit 18 are determined. It judges repeatedly until it is judged. If it is determined in step 940 that image data up to the Nth sheet has been output to the printing unit 18, the fifth copying process is terminated.

  On the other hand, if it is determined in step 938 that the stop factor file is written with a character string indicating that reading has been stopped because it has been detected by extraction of reading prohibition information, the next step In 942, the reading prohibition release authority registration table 24 stored in the HDD 12b is read, and the record 26 in the field 28 in which the user ID input by the user is registered together with the copy processing instruction is specified. Then, the read prohibition release authority registered in the field 30 of the specified record 26 is acquired.

  In the next step 944, it is determined whether or not the read prohibition release authority acquired in step 942 indicates “permit”, so that the user who issued the copy processing instruction has the authority to cancel the read prohibition. Determine whether.

  If it is determined in step 944 that the read prohibition release authority does not indicate “permitted”, it is determined that the user does not have the authority to cancel the read prohibition, and in step 946 the job cancel is performed. Do. Here, the job cancel is regarded as having not been given the current copy processing instruction, and is copied from the printing unit 18 by discarding all the image data stored in the HDD 12b by the fifth copy processing executed this time. This can be executed by preventing an object (output object) from being output.

  In the next step 948, the process proceeds from step 944 to step 946. If the process proceeds from step 946 to step 948, the user ID of the user who issued the copy process instruction and the copy process instruction are input, but the job cancel is performed. A log including information indicating that the process has been performed is generated, and the generated log is stored in the HDD 12b. Then, the fifth copying process is finished. In the fifth copy process executed this time, if it is determined in step 954 that will be described later that the instruction is a restart instruction, information for identifying the user who has given the restart instruction, for example, a user ID is entered. The generated log (history information) is generated, and the generated log is stored in the HDD 12b. Also, in the fifth copy process executed this time, if it is determined that the instruction is a skip instruction in step 954 described later, information for specifying the user who has made the skip instruction, for example, a user ID is entered. The generated log (history information) is generated, and the generated log is stored in the HDD 12b.

  On the other hand, if it is determined in step 944 that the read prohibition release authority indicates “permitted”, it is determined that the user has the authority to cancel the read prohibition, and the next step 950 cancels. Corresponding to the information indicating the original paper 56 registered in the prohibited original list file among the image data up to the Mth sheet stored in the HDD 12b. A skip button for accepting a skip instruction for restarting reading that has been canceled and output to the printing unit 18 except for the image data to be processed, the fifth copy executed this time, assuming that there was no current copy processing instruction. By discarding all the image data stored in the HDD 12b by the copying process, the copy unit 18 is prevented from outputting a copy. Job cancel button for accepting an instruction of job cancellation, and a message for prompting the user to select these buttons to control the display of U / I14 to appear that. As a result, as shown in FIG. 18, the reading prohibition release button 69, the job cancel button 71, the skip button 73, and the message 75 are displayed on the U / I 14. In this way, by displaying the read prohibition release button 69 for accepting a resume instruction for resuming reading, the user is notified that a resume instruction for resuming the suspended reading is accepted.

  In the next step 952, when one of the reading prohibition release button 69, the job cancel button 71, and the skip button 73 displayed on the U / I 14 is pressed by the user, it is output from the U / I 14. It is determined whether an instruction corresponding to the button has been received.

  If it is determined in step 952 that the instruction has been received, the process proceeds to the next step 954. In step 954, whether the received instruction is a restart instruction to resume reading that has been cancelled, or, among the image data up to the Mth sheet stored in the HDD 12b, the original paper registered in the prohibited original list file It is determined whether the instruction is a skip instruction for restarting reading that has been canceled and output to the printing unit 18 except for image data corresponding to information representing 56, or a job cancellation instruction.

  If it is determined in step 954 that the instruction is a job cancel instruction, the process proceeds to the next step 946 to perform the processing described above.

  If it is determined in step 954 that the instruction is a restart instruction, the process proceeds to the next step 956. In step 956, the image data up to the Mth sheet stored in the HDD 12 b is output to the printing unit 18. As a result, an output product in which an image based on the image data up to the Mth sheet is formed is output from the printing unit 18.

  In the next step 958, the value of the reading flag is set to a value indicating a mode for reading, for example, “0”. As a result, a mode for reading is set.

  In the next step 960, the stop factor file stored in the HDD 12b is cleared (that is, all written contents are erased).

  In the next step 962, an instruction for reading the original paper 56 is output to the image reading device 16 so as to restart the reading that has been stopped. Then, the process returns to step 902.

  On the other hand, if it is determined in step 954 that the instruction is a skip instruction, the process proceeds to the next step 964. In step 964, image data corresponding to information representing the original paper 56 registered in the prohibited original list file is excluded from the image data up to the Mth sheet stored in the HDD 12b, and is output to the printing unit 18. As a result, the printing unit 18 forms an image based on the image data excluding the image data corresponding to the information representing the original paper 56 registered in the prohibited original list file from the M-th image data. Output is output. Then, the process proceeds to Step 958.

  The first to fifth embodiments have been described above. In step 418 of the second copying process and the fourth copying process, thumbnail images (display images) of the Nth to Kth image data stored in the HDD 12b are generated. As shown in FIG. 19, the display of the U / I 14 is controlled so that each generated thumbnail image 80 is displayed on the U / I 14 so that the user can select one thumbnail image from the plurality of thumbnail images 80. When the reading prohibition release button 68 is pressed when 80 is selected, the original paper 58 of the page after the page of the original paper 58 corresponding to the selected thumbnail image 80 and until the reading is stopped. Alternatively, the image reading device 16 may be controlled to resume reading from the original paper 58 on which the image 64 has not been read by the image reading device 16.

  Further, in step 418 of the second copying process and the fourth copying process, thumbnail images (display images) of the respective image data from the Nth sheet to the Kth sheet stored in the HDD 12b are generated. As shown in FIG. 19, the display of the U / I 14 is controlled so that each generated thumbnail image 80 is displayed on the U / I 14 so that the user can select one thumbnail image from the plurality of thumbnail images 80. If 80 is selected and the skip button 72 is pressed, the image data stored in the HDD 12b and the image of the original paper 58 on the page preceding the original paper 58 corresponding to the selected thumbnail image 80 are displayed. In addition to discarding data from the HDD 12b, the original paper 58 of the pages following the original paper 58 corresponding to the selected thumbnail image 80 is displayed. Te, from the document sheet 58 on which the image 64 is not read by the image reading apparatus 16 by the time the reading is aborted, may be controlled image reading device 16 to resume reading.
