Description

  The present invention relates to an image forming apparatus that is used in a device such as a digital multi-function peripheral to read a document and a control method thereof.

  This type of apparatus includes an ADF (Auto Document Feeder) reading function for easily reading a series of sheet originals composed of a plurality of sheets, and a manual placement for reading an original such as a book original. Some have a reading function.

  Here, in the ADF reading function, the original is read by the image sensor while conveying the original set on the original tray one by one. In the manual placement reading function, the image sensor is moved along the document placed on the document table, and the document on the document table is read by the image sensor.

  Therefore, the user can read various types of documents using a reading function suitable for the document to be read.

Japanese Patent Laid-Open No. 11-177805

  However, in the original reading apparatus having the ADF reading function and the manual placement reading function as described above, the original reading by the ADF reading function and the original reading by the manual placement reading function are performed completely separately.

  Therefore, for example, when a new series of originals is obtained by combining a copy original from a book original with a copy original from a series of sheet originals made up of a plurality of sheet papers, the user can use the ADF for the series of sheet originals. A copy using the reading function and a copy using the manual placement reading function relating to the book original must be performed separately, and the output copy originals must be rearranged manually.

  If a copy of a book original is added after a copy of a sheet original, or vice versa, the copy original can be discharged in the desired order by adjusting the copy order. There is no need to combine the manuscripts manually.

  However, when a plurality of copies are used, if a mechanical sorter is not provided, the copy original is discharged so that manual rearrangement is not required even if the copy order is adjusted. It is impossible.

  As described above, conventionally, image data obtained by reading an original using the ADF reading function and image data obtained by reading an original using the manual placement reading function are completely different data. Therefore, image data is generated for a series of originals composed of a combination of an original suitable for reading using the ADF reading function and an original suitable for reading using the manual placement reading function. I couldn't.

  The present invention has been made in view of such circumstances, and the object of the present invention is to perform a series of document image data while performing both reading by the ADF reading function and reading by the manual placement reading function. An object of the present invention is to provide an image forming apparatus that can be generated and a control method thereof.

  In order to achieve the above object, an image forming apparatus according to an embodiment of the present invention reads the document at the reading position while sequentially transporting the document set on the document tray to a predetermined reading position. First reading means, second reading means for reading a document placed on the document table without carrying the document, and an image generated by reading the document by the first reading means and the second reading means Storage means for storing data, mode setting means for setting a special mode for waiting for image formation after an original is read by the first reading means or the second reading means, and the mode setting means for setting the special mode. When set, when all the documents set on the document tray have been read by the first reading unit, and placed on the document table by the second reading unit. In at least one of the cases where the document has been read, an accepting unit that accepts an instruction to continue document reading and an instruction to complete document reading, and determines whether or not the document is set on the document tray When the determination unit determines that a document is set on the document tray when the receiving unit receives an instruction to continue reading the document, the first reading unit reads the document. A reading control unit that causes the second reading unit to start reading a document when the determination unit determines that a document is not set on the document tray; and an instruction to the effect that the document reading is completed by the receiving unit. The image data generated by reading the original by the first reading unit or the second reading unit before being accepted is converted into a series of image data of the original. When the storage control unit to be stored in the storage unit and an instruction to the effect of completion of document reading are received by the receiving unit, the image of the series of image data stored in the storage unit is recorded on the recording sheet. Image forming means for forming the image.

  According to the present invention in which such a measure is taken, ADF reading by the first reading unit and manual placement reading by the second reading unit can be mixed to sequentially read image data of each page of a series of documents. Thus, an image forming apparatus capable of generating a series of document image data while performing both reading by the ADF reading function and reading by the manual placement reading function is provided.

  If the special mode is not set, designation by the accepting unit is not waited, and it is not necessary for the user to perform designation, and if necessary, by reading a plurality of documents by the first reading unit and the second reading unit. The image forming apparatus can perform processing for storing the generated image data in a storage unit as image data of a series of documents.

  Hereinafter, an embodiment of a digital multi-function peripheral configured by applying a document reading apparatus of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a main configuration of the digital multifunction peripheral according to the present embodiment.

  In this figure, a digital multi-function peripheral according to the present embodiment is surrounded by a broken line and denoted by reference numeral 1.

  As shown in this figure, the digital multifunction peripheral 1 of this embodiment includes a CPU 11, a ROM 12, a RAM 13, an image memory 14, an image sensor 15, an image processing unit 16, an image sensor transfer mechanism unit 17, a document transport mechanism unit 18, and a printer 19. , An encoder / decoder 20, a network control circuit (NCU) 21, a modem 22, a personal computer interface (hereinafter referred to as a PC interface) 23, and an operation panel 24, which are connected via a system bus 25. They are connected to each other.

  The CPU 11 realizes an operation as a digital multifunction peripheral by performing control processing for overall control of each part of the digital multifunction peripheral based on a control program stored in the ROM 12.

  The ROM 12 stores a control program for the CPU 11 and the like.

  The RAM 13 is used for storing various information necessary for the CPU 11 to perform various processes.

  The image memory 14 stores and stores image data related to image data processing such as transmission / reception, image reading, or image printing.

  The image sensor 15 uses a CCD line sensor, for example, and generates an image signal by performing main scanning on a document placed on a document table (not shown).

  The image processing unit 16 is connected to the image sensor 15. The image processing unit 16 generates image data by performing various correction processes such as digitization, shading correction and dark correction on the image signal generated by the image sensor 15.

  The image sensor transfer mechanism unit 17 reciprocates the image sensor 15 along the document table for sub-scanning.

  The document transport mechanism 18 sequentially transports documents set on a document tray (not shown) one by one onto the document table.

  The printer 19 prints an image indicated by the image data on a recording sheet.

  The encoding / decoding unit 20 compresses and encodes image data and decodes the compressed and encoded image data.

  A PSTN line 2 accommodated in a Public Switched Telephone Network (PSTN) is connected to the NCU 21. The NCU 21 performs state monitoring, transmission processing to the network, and the like regarding the connected PSTN line 2. The NCU 21 also equalizes the facsimile transmission signal sent to the PSTN line 2 and sets the level.

  The modem 22 is connected to the NCU 21. The modem 22 modulates the image data and the control data, and generates a facsimile transmission signal and a control signal for sending out to the PSTN line 2. The modem 22 demodulates the facsimile transmission signal and control signal that arrives via the PSTN line 2 and reproduces image data and control data.

  A personal computer (PC) 3 is connected to the PC interface 23 via, for example, a cable. The PC interface 23 mediates transfer of control commands and image data between the CPU 11 and the personal computer 3.

  The operation panel 24 includes a key input unit for receiving various instruction inputs to the CPU 11 by the user, a display unit for displaying various information to be notified to the user, and the like.

  By the way, the control means realized by the CPU 11 operating based on the control program stored in the ROM 12 includes a mode switching means, a continuation designation receiving means, and a reading method selection, in addition to the well-known general ones in the facsimile apparatus. Means, storage control means, condition designation accepting means, and condition setting means.

  Here, the mode switching means causes a built job process, which will be described later, to be performed only when it is requested to perform a series of documents using both the ADF reading function and the manual placement reading function.

  The continuation designation accepting unit accepts designation as to whether or not to continue the document reading after one document reading is completed during the built job processing.

  The reading method selection means selects one of the ADF reading function and the manual placement reading function based on the document setting state on the document tray during the built job processing, and starts reading the document with the reading function.

  The accumulation control unit accumulates the image data generated until the completion designation of document reading is received by the continuation designation receiving unit in the image memory 14 as a series of document image data.

  The condition designation accepting unit accepts designation of image quality and density predetermined conditions relating to reading when the continuation designation accepting unit waits for designation as to whether or not to continue document reading.

  When the continuation specification accepting unit accepts the continuation specification of the document reading and the document reading is performed, the condition setting unit is configured to read the updated reading conditions according to the specification newly accepted by the condition designation accepting unit. Control to read.

  Next, the operation of the digital multi-function peripheral configured as described above will be described in accordance with the processing procedure of the CPU 11.

  First, when a certain job is finished and a standby state is entered, the CPU 11 starts a standby process as shown in FIG.

  In this standby process, the CPU 11 first waits for a key operation by the user on the operation panel 24 (step ST1). At this time, the display screen SC1 shown in FIG. In FIG. 3, a symbol C is a cursor displayed on each display screen.

  If the user performs any key operation on the operation panel 24 from this state, the CPU 11 accordingly determines whether the key operation is a press of the Enter key or an item selection operation (step). ST2 and step ST3).

  Here, when the performed key operation is neither the pressing of the Enter key nor the item selection operation, the CPU 11 shifts the processing to another processing according to the content of the key operation.

  However, if an item selection operation such as pressing of a key for designating forward or reverse selection items is performed, for example, the CPU 11 accepts the item selection operation (step ST4). At this time, the display position of the cursor C on the display screen SC1 is changed according to the accepted item selection operation. That is, here, a selection operation for selecting any one of the special functions of page addition, built job, and mode memory is accepted.

  Thereafter, the CPU 11 returns to the key operation waiting state in step ST1.

  If the Enter key is pressed while the CPU 11 is in the standby state of step ST1, the CPU 11 subsequently determines whether or not the selected item is a built job (step ST5).

  If the built job is not selected here, the CPU 11 shifts the process to another process corresponding to the selected item.

  However, if the built job is selected, the CPU 11 then waits for the Enter key to be pressed or an item selection operation to be performed on the operation panel 24 (step ST6 and step ST7). At this time, the display screen SC2 shown in FIG.

  If an item selection operation is performed here, the CPU 11 accepts the item selection operation (step ST8). At this time, the display position of the cursor C on the display screen SC2 is changed according to the accepted item selection operation. That is, here, a selection operation for selecting ON / OFF of a built job is accepted.

  On the other hand, if the Enter key is pressed, the CPU 11 subsequently determines whether or not the selection item is “ON” (step ST9).

  The CPU 11 activates the built-in job process only when “ON” is selected here (step ST10), and then terminates the standby process. If “OFF” is selected, the CPU 11 returns the process to step ST11.

  Now, when the built-in job processing is activated in the above-described standby processing, the CPU 11 executes the built-job processing as shown in FIGS.

  In the following, the user is going to make a copy of a new series of originals with one book original added after the series of sheet originals made of at least one sheet of paper, and the sheet. A series of sheet originals made of paper is read by the ADF reading function under the default reading conditions, and a book original is read by changing the image quality of the reading conditions to “Photo” and the density to “Toner Save”. The built job processing will be described in detail with a case where each is performed by the reading function as a main subject.

  When the built job process is started, the CPU 11 first initializes the document size to “NULL” (step ST21 in FIG. 4).

  Thereafter, the CPU 11 waits for a key operation by the user on the operation panel 24 (step ST22). At this time, the display screen SC3 shown in FIG. This display screen SC3 shows default copy conditions.

  If the user performs any key operation on the operation panel 24 from this state, the CPU 11 accordingly determines whether or not the key operation is a press of the start key (step ST23).

  At this time, the user can change the image quality and density by pressing an image quality setting key and density setting key provided on the operation panel. That is, if any key other than the start key is operated, the CPU 11 shifts the process to accepting copy condition designation (step ST24), and accepts a change designation of copy condition here. If necessary, the display screen on the display unit of the operation panel 24 is also changed. Thereafter, the CPU 11 returns to the key operation waiting state in step ST22.

  However, here, since the user is going to read with the default condition first, the user presses the start key without specifying the condition.

  If the start key is pressed, the CPU 11 checks whether or not a document is set on the document tray (step ST25).

  Here, since the user intends to read a series of sheet originals made of at least one sheet of paper by the ADF reading function, the sheet originals are set on the original tray before the start key is pressed. Yes.

  Accordingly, in step ST25, the CPU 11 can determine that there is a document on the document tray. In this case, the CPU 11 checks whether or not the document size is set to “NULL” (step ST26). When the document size is set to “NULL”, that is, when the first document reading is performed in the current built job, the CPU 11 sets the document size to “ADF size” (step ST27). However, if a document size other than “NULL” has already been set, the CPU 11 keeps the document size unchanged. Here, since the first reading is to be performed, the document size is set to “ADF size”.

  Subsequently, the CPU 11 executes ADF input processing for performing document reading by the ADF reading function (step ST28). In this ADF input process, the sheet document set on the document tray is conveyed one by one onto the document table by the document conveying mechanism 18, and the sheet document placed on the document table is thereby transferred to the image sensor. This is a well-known process in which main scanning is performed by the image sensor 15 while performing sub-scanning by the mechanism unit 17. The image data generated by the image sensor 15 and the image processing unit 16 is stored in the image memory 14. At this time, if there is already stored image data in the image memory 14 in the current built job, the newly generated image data is assumed to follow the already stored image data in the image memory 14. to manage.

  This ADF input process is normally performed until reading of all the sheet documents set on the document tray is completed. However, if the user gives an interruption instruction in the middle, only the reading so far is valid. And even if ADF input processing is complete | finished by either of these methods, CPU11 performs the following processes continuously.

  While the ADF input process is being executed, the display screen SC4 shown in FIG. 3 is displayed on the display unit of the operation panel 24.

  When the ADF input processing is completed, the CPU 11 updates the total number of originals by adding the number of readings by the current ADF input processing to the total number of originals (reset to “0” at the start of the current built job processing). (Step ST29).

  After that, the CPU 11 waits for a key operation by the user on the operation panel 24 (step ST30 in FIG. 5). At this time, the display screen SC5 shown in FIG.

  If the user performs any key operation on the operation panel 24 from this state, the CPU 11 accordingly determines whether or not the key operation is pressing any one of the image quality setting key, the density setting key, and the start key. (STEP ST31 to ST33).

  In this case, the user next reads the book document. At the time of reading, the image quality of the reading conditions is changed to “photograph” and the density is changed to “toner save”. Is called.

  First, if the image quality setting key is pressed to change the image quality, the CPU 11 performs image quality setting processing (step ST34). In this image quality setting process, the display screen SC6 shown in FIG. Then, the CPU 11 accepts a selection designation as to whether the image quality is an automatic mode, a photo mode, or a character mode, and uses the mode selected when the Enter key is pressed as a mode to be used for subsequent document reading. Set.

  That is, here, the user sets the picture quality to “photograph”, and accordingly, appropriately selects and presses the Enter key with the cursor placed on “photo mode” as shown in the display screen SC6 of FIG. As a result, the photo mode is set as a mode to be used for subsequent document reading.

  When the image quality setting process is completed, the CPU 11 returns to the key operation waiting state in step ST30. Therefore, a display screen SC7 shown in FIG.

  On the other hand, if the density setting key is pressed to change the density, the CPU 11 performs density setting processing (step ST35). In this density setting process, the display screen SC8 shown in FIG. The CPU 11 accepts a selection designation of whether the density is an automatic mode, a manual mode, or a toner save mode, and uses the mode selected when the Enter key is pressed for the subsequent document reading. Set as.

  That is, here, since the user sets the density to “toner save”, the user presses the enter key while appropriately selecting and specifying the “toner save mode” as shown in the display screen SC8 of FIG. To do. As a result, the toner save mode is set as a mode to be used for subsequent document reading.

  When the density setting process is completed, the CPU 11 returns to the key operation waiting state in step ST30. Therefore, the display screen SC9 shown in FIG.

  In the key operation waiting state in step ST30, an item selection operation for reading the next original or starting printing is also accepted, and the key operation is performed by any one of the image quality setting key, the density setting key, and the start key. If not, the CPU 11 accepts this item selection operation (step ST36). At this time, the display position of the cursor C on the display screen SC9 is changed according to the accepted item selection operation.

  The user selects the next original reading by the item selection operation, places the book original on the original table to read the book original, and then presses the start key.

  Then, after receiving an item selection operation for selecting the next original reading in step ST36, the CPU 11 recognizes that the start key is pressed in step ST30 and step ST33.

  In response to this, the CPU 11 checks whether or not the selection item is “print start” (step ST37).

  Here, since the next original reading is selected, the CPU 11 determines that the selected item is not the start of printing, and shifts the processing to step ST25.

  At this time, since the book document is placed on the document table and no document is set on the document tray, the CPU 11 determines in step ST25 that there is no document on the document tray.

  In this case, the CPU 11 subsequently checks whether or not the document size is set to “NULL” (step ST38). When the document size is set to “NULL”, that is, when the first document reading is performed in the current built job, the CPU 11 sets the document size to “manual placement size” (step ST39). However, if a document size other than “NULL” has already been set, the CPU 11 keeps the document size unchanged. Here, since the document size is already set to “ADF size”, the CPU 11 keeps the document size as “ADF size” without performing the process of step ST39.

  Subsequently, the CPU 11 executes manual placement input processing for performing document reading by the manual placement reading function (step ST40). This manual placement input process is a well-known process of reading a document placed on a document table by performing main scanning with the image sensor 15 while performing sub-scanning with the image sensor transfer mechanism unit 17. In this manual placement input process, the document transport mechanism 18 does not operate. The image data generated by the image sensor 15 and the image processing unit 16 is stored in the image memory 14. At this time, if there is already stored image data in the image memory 14 in the current built job, the newly generated image data is assumed to follow the already stored image data in the image memory 14. to manage.

  During the manual input process, a display screen SC10 shown in FIG. 3 is displayed on the display unit of the operation panel 24.

  When the manual placement input process is completed, the CPU 11 updates the total number of originals by adding “1” which is the number of readings by the current manual placement input process to the total number of originals (step ST41).

  After that, the CPU 11 shifts to the key operation waiting state in step ST30. Accordingly, the display screen SC11 shown in FIG. 3 is displayed on the display unit of the operation panel 24.

  Therefore, the user can repeat document reading after changing the image quality and density as necessary.

  However, since all the originals have been read here, the user selects the start of printing by the item selection operation and then presses the start key.

  Then, after accepting an item selection operation for selecting the start of printing in step ST36, the CPU 11 recognizes that the start key is pressed in steps ST30 and ST33.

  Further, the CPU 11 determines in step ST37 that the selection item is “start printing”, and executes the memory printing process (step ST42). In this memory printing process, the CPU 11 causes the printer 19 to perform printing using each of a series of image data stored in the image memory 14 during the current built job process. That is, when reading is performed a plurality of times, the printer 19 is caused to perform printing using each of the image data generated by each of the plurality of readings.

  During this memory printing process, the display screen SC12 shown in FIG. 3 is displayed on the display unit of the operation panel 24.

  When the printing is completed, the CPU 11 ends the current built job process.

  As described above, according to the present embodiment, when the start of reading is instructed during built job processing, either the ADF reading function or the manual placement reading function is selected, and the original using that function is selected. Reading is performed, but every time one document reading is completed, a user designation indicating whether or not to continue document reading is accepted. When continuous document reading is designated, either the ADF reading function or the manual placement reading function is selected, the document is read using that function, and the image data generated as a result Is stored in the image memory 14 as a continuation of the image data generated by reading the original document. When the start of printing is instructed, a series of image data stored in the image memory 14 is printed as a series of copy originals.

  Therefore, when the user wants to obtain a series of copy originals combining a manuscript suitable for reading with the ADF reading function and a manuscript suitable for reading with the manual placement reading function and combining them, 1 Each time ADF scanning or manual scanning is completed, each document is set on the document tray or document table according to the order of the copied documents, and the next document reading is instructed, and all the documents are read. Then, it is possible to print a desired copy document by instructing the start of printing.

  Here, since all the image data of a series of copy originals are stored in the image memory 14, when printing a plurality of copies, even if a mechanical sorter is not provided, the printing order control by software control is performed. Thus, it is possible to output copy originals in various forms such as a book or stack, and the user does not need to manually rearrange the output copy originals.

  Further, in this embodiment, since it is automatically determined according to the document setting state whether the ADF reading function or the manual reading function is used to read the document, the user only gives an instruction to set the document and start reading. This can be done, reducing the burden on the user.

  In the present embodiment, the built job processing for printing a series of copy originals by reading a plurality of times as described above is a special mode that operates only when selected by the user. It is possible to set a simple mode of user operation such as automatically starting printing immediately after reading a document.

  Further, in this embodiment, when receiving a user designation for reading the next original or starting printing, the designation of the reading condition is also accepted. If the reading condition is designated here, the subsequent reading is performed. Since the above condition is changed to a newly designated condition, it is possible to perform reading under an appropriate condition according to the state of each original.

  In the present embodiment, even when the ADF reading process is interrupted, the built job process is continued, and reading of a new document can be continued. Therefore, for example, even if a user mistakenly sets a sheet document to be a page after the book document together with a sheet document to be a page before the book document on the document tray, the ADF reading is appropriately performed. It is possible to provide flexibility in operation, such as interrupting reading of a book document by interrupting at timing.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the document reading apparatus according to the present invention is applied to a digital multi-function peripheral. However, it can also be applied to other devices such as a facsimile machine and a copying machine, or a generated image. It can also be realized as an independent document reading device that outputs data to an external device. In other words, the use form of the generated image data is not limited. Therefore, in the above embodiment, the built job processing can be performed not only at the time of copying but also at the time of facsimile transmission.

  In the above-described embodiment, the image sensor 15, the image processing unit 16, and the image sensor transfer mechanism unit 17 are commonly used for ADF reading and manual placement reading. The reading means and the reading means for manual placement reading may be completely separate.

  In the above-described embodiment, whether the ADF reading function or the manual placement reading function is used to determine whether the document is read is determined based only on the setting state of the document on the document tray. The determination may be made on the basis of only the state, or on the basis of the state of the original set on the original tray and the original table. Further, it is not always necessary to automatically determine which of the ADF reading function and the manual placement reading function is used, and it may be determined based on the user designation which document is to be read preferentially. .

  In the above embodiment, the built job is continued even when the ADF reading process is interrupted. However, the built job may be terminated when the ADF reading process is interrupted. In this way, when it is desired to interrupt the copying operation itself during the ADF reading process, the user only needs to perform an operation of one interruption instruction, and the user operation is simplified.

  In the above embodiment, the built job processing is in the special mode, but the built job processing may be executed at normal times.

  In addition, various modifications can be made without departing from the scope of the present invention.
