Description

The present invention relates to an image forming device with a copy function.

Some image forming devices, such as copiers and multifunction devices, are equipped with a document reading unit that reads images from documents and have a copy function. The following Patent Document 1 describes a technology that makes it unnecessary to read the document again by the document reading unit when an additional copy is required.

Chinese Patent Publication No. 1842118

In copiers and other devices, the user can set the number of copies (number of copies to be printed) as desired, but when copying a multi-page document at once, it is not possible to increase the number of copies to be printed for a specific page alone. As a result, in order to increase the number of copies to be printed for a specific page alone, it was necessary to make an additional copy of that specific page. The invention described in the above-mentioned Patent Document 1 proposes a technology that makes it easy to make additional copies, but it is not possible to change the setting of the number of copies to be printed for a specific page alone.

The present invention has been developed in consideration of the above circumstances, and aims to change the number of copies to be printed only for specific pages when copying a multi-page document at once.

An image forming apparatus according to one aspect of the present invention includes a document reading unit that sequentially reads a document containing multiple pages to obtain a document image of each document, an image forming unit that forms the image on a recording medium and prints it, an operation unit that accepts input of instructions from a user, a setting unit that sets the number of copies to be printed for each page or page range of the document image in accordance with the user instructions accepted by the operation unit, and a control unit that causes the image forming unit to form the document image obtained by reading the document reading unit on the recording medium in the number of copies set for each page or page range by the setting unit.

According to the present invention, it is possible to change the number of copies to be printed for each of multiple original images for each page or for each page range, as specified by the user, and form the images. Therefore, when copying multiple pages of an original at once, it is possible to change the setting of the number of copies to be printed only for specific pages.

The image forming apparatus according to one embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the external appearance of an image forming apparatus according to one embodiment of the present invention. The image forming apparatus 1 is a multifunction machine that combines multiple functions such as a copy function, a printer function, a scanner function, and a facsimile function, and is configured to include a document feed unit 6, a document reading unit 5, an image forming unit 12, a paper feed unit 14, and an operation unit 47.

The document feed unit 6 is configured to be openable and closable by a hinge or the like (not shown) on the top surface of the document reading unit 5, and functions as a document pressing cover when reading a document placed on a platen glass (not shown). The document feed unit 6 is also called an ADF (Auto Document Feeder), and includes a document placement tray 61 on which documents are placed, and a document discharge tray 62 provided below the document placement tray 61. The document feed unit 6 supplies documents placed on the document placement tray 61 one by one to the document reading unit 5, and discharges the documents to the document discharge tray 62.

The following describes the case where a document reading operation is performed by the image forming apparatus 1. The document reading unit 5 optically reads the image of the document supplied to the document reading unit 5 by the document feeding unit 6, or the document placed on the platen glass, and generates image data. The image data generated by the document reading unit 5 is stored in an image memory (not shown) or the like. The document reading unit 5 is also capable of sequentially reading images of multiple pages of documents sent from the document feeding unit 6.

The following describes the case where an image forming operation is performed by the image forming device 1. Based on image data generated by a document reading operation or image data received from a computer as an external device (e.g., a personal computer) connected to a network, the image forming unit 12 forms a toner image on recording paper as a recording medium fed from the paper feed unit 14.

The image forming unit 12 is equipped with a mechanism for forming color images. For example, the image forming unit 12 is equipped with an image forming unit for magenta, an image forming unit for cyan, an image forming unit for yellow, and an image forming unit for black. In each image forming unit for each color, the surface of the photosensitive drum is uniformly charged, the surface of the photosensitive drum is exposed to light, an electrostatic latent image is formed on the surface of the photosensitive drum, the electrostatic latent image on the surface of the photosensitive drum is developed into a toner image, and the toner image on the surface of the photosensitive drum is primarily transferred to the intermediate transfer belt. As a result, a color toner image is formed on the intermediate transfer belt. This color toner image is secondarily transferred to the recording paper transported from the paper feed unit 14 in the nip area between the intermediate transfer belt and the secondary transfer roller.

The recording paper on which the toner image is formed by the image forming unit 12 undergoes a fixing process in the fixing unit 13 (FIG. 2) described below, and the recording paper after the fixing process is discharged to the discharge tray 151. The paper supply unit 14 includes multiple paper supply cassettes 141.

The operation unit 47 has hard keys for receiving instructions, and receives instructions such as an instruction to perform an image forming operation from the operator for various operations and processes that can be performed by the image forming device 1 in response to operation of the hard keys. The operation unit 47 has a display unit 473 that displays operation guides and the like for the operator. The operation unit 47 also receives input of instructions from the user via the touch panel of the display unit 473, based on the user's operation (touch operation) on the operation screen displayed on the display unit 473 or the user's operation on the physical keys.

The display unit 473 is composed of an LCD (Liquid Crystal Display) or the like. The display unit 473 is equipped with a touch panel. When the operator touches a button or key displayed on the screen, the touch panel accepts an instruction associated with the touched position.

Figure 2 is a functional block diagram showing the main internal configuration of the image forming device 1 according to the first embodiment. The image forming device 1 includes a control unit 10, a document feed unit 6, a document reading unit 5, an image forming unit 12, a fixing unit 13, a paper feed unit 14, an operation unit 47, and a memory unit 8.

The fixing unit 13 applies heat and pressure to the recording paper on which the toner image has been formed by the image forming unit 12, fixing the toner image to the recording paper. The recording paper that has been subjected to the fixing process is discharged to the discharge tray 151 (Figure 1).

The memory unit 8 is a large-capacity storage device such as a hard disk drive (HDD) or a solid state drive (SSD), and stores various control programs, etc.

The control unit 10 includes a processor, a RAM (Random Access Memory), a ROM (Read Only Memory), and a dedicated hardware circuit. The processor is, for example, a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), or an MPU (Micro Processing Unit). The control unit 10 includes a control unit 100 and a setting unit 101.

The control unit 10 functions as a control unit 100 and a setting unit 101 through operation of the processor in accordance with a control program stored in the storage unit 8. However, the control unit 100 and the like can also be configured by hardware circuits, without relying on operation in accordance with a control program by the control unit 10. The same applies to each embodiment below unless otherwise stated.

The control unit 100 is responsible for the overall operational control of the image forming device 1. The control unit 100 is connected to the document feed unit 6, the document reading unit 5, the image forming unit 12, the fixing unit 13, the paper feed unit 14, the operation unit 47, and the memory unit 8, and performs drive control of each of these units and executes various processes required for image formation by the image forming device 1. For example, the control unit 100 controls the image forming unit 12 to execute a copy process in which the document image obtained by document reading by the document reading unit 5 is formed on a recording medium.

The setting unit 101 sets the number of copies to be printed according to instructions from the user received by the operation unit 47. The control unit 100 controls the image forming unit 12 to execute the above copy process based on the settings made by the setting unit 101.

The setting unit 101 also sets the number of copies to be printed for each page or page range of the original image as specified by the user. The control unit 100 causes the image forming unit 12 to form an image of each original image with the number of copies to be printed for each original image set by the setting unit 101. For example, the setting unit 101 assigns page numbers to each original image corresponding to each original in the order in which the originals are read by the original reading unit 5, and sets the number of copies for each original image based on the assigned page numbers.

Figures 3 (A) and (B) are diagrams showing an example of an operation screen that the control unit 100 causes the display unit 473 to display. The operation screen G1 shown in Figures 3 (A) and (B) is an operation screen for accepting from the user the designation of the number of copies to be printed for each page number or for each page range. The operation screen G1 shown in Figures 3 (A) and (B) is provided with text boxes BX1 and BX2 for displaying text (character strings) entered by the user.

Text box BX1 displays the page number of the original image for which the number of copies to be printed is to be set, as input by the user. Text box BX2 displays the number of copies to be printed specified by the user for the original image of the page number displayed in text box BX1. The user inputs, for example, by operating the operation unit 47, the page number of the original image for which the number of copies to be printed is to be set, and the number of copies to be printed for the original image of that page number. The setting unit 101 accepts the page number and the number of copies to be printed input to the operation unit 47.

Figure 3 (B) shows a state where "1-2" is displayed in text box BX1 and "5" is input and displayed in text box BX2. Operation screen G1 shown in Figure 3 (B) shows a state where the number of copies to be printed for the first and second page original images is specified as 5 copies.

In addition, the operation screen G1 has an operation button B1 for instructing addition, indicated by a plus mark, and an operation button B2 marked "OK". When the user taps the operation button B1 and the operation unit 47 accepts the instruction associated with the operation button B1, the control unit 100 adds and displays text boxes BX1 and BX2, which display the page number of the document image for which the number of copies is to be set and the input contents of the number of copies to be printed, to the operation screen G1, as shown in FIG. 4(A). The operation screen G1 shown in FIG. 4(B) further shows a state in which the number of copies to be printed for the fifth page of the document image is specified as 2 copies and this is displayed.

When the user taps the operation button B2 and the operation unit 47 accepts the instruction associated with the operation button B2, the setting unit 101 sets the number of copies to be printed for each page number or page range of the original image based on the content displayed on the operation screen G1, i.e., the page number of the original image for which the number of copies to be printed is to be set and the content of the number of copies to be printed that is accepted at this point. The setting unit 101 sets the number of copies to a default value (1 copy in this embodiment) for the original image of the page for which the number of copies to be printed was not specified via the operation screen G1.

For example, as shown in FIG. 4B, when the number of copies of the original image to be printed is specified by the user, the setting unit 101 sets the number of copies to be printed of the first and second pages to 5 copies as shown in FIG. 5, and when the number of copies to be printed of the fifth page is set to 2 copies, it sets the number of copies to be printed of the other pages for which no specification by the user has been accepted to 1 copy (default value).

Next, an example of the process for setting the number of copies to be printed for each document image in the image forming device 1 according to the first embodiment will be described with reference to the flowchart shown in FIG.

When the operation unit 47 receives an instruction from a user to execute document reading, the control unit 100 controls the document feed unit 6 and the document reading unit 5 to read images of multiple documents placed on the document placement tray 61 (S1). The setting unit 101 assigns page numbers to each document image in the order of the documents read by the document reading unit 5 (S2).

Then, the control unit 100 causes the display unit 473 to display an operation screen G1 such as the example shown in FIG. 3(A) (S3). During this display, the setting unit 101 sets the number of copies to be printed for each page number of the original image accepted by the operation unit 47 based on a user operation performed via the operation screen G1 (S4). FIG. 5 shows an example of the page numbers assigned to each original image and the number of copies to be printed for each page number. The control unit 100 performs a copy process to form an image of each original image for the number of copies to be printed set by the setting unit 101 (S5).

For example, when the number of copies to be printed for each page number is set as shown in FIG. 5, and five pages of the original are read in sequence by the original reading unit 5, a print result such as that shown in FIG. 7 is obtained. For example, the first original image read is assigned the page number of the first page as shown in FIG. 7, and five copies are printed. For the original images of the third and fourth pages, for which the number of copies to be printed was not specified, the setting unit 101 sets the number of copies to be printed to one.

According to the first embodiment, it is possible to change the number of copies to be printed for each of multiple original images for each page or for each page range, as specified by the user, and form the images. Therefore, when copying multiple pages of an original at once, it is possible to change the setting of the number of copies to be printed only for specific pages.

Figure 8 is a functional block diagram showing an outline of the main internal configuration of an image forming device 1 according to a further embodiment. Description of configurations similar to those of the image forming device 1 according to the first embodiment will be omitted. In this embodiment, the control unit 10 functions as a character recognition unit 102 and a page number detection unit 103 in addition to the control unit 100 and setting unit 101, due to the operation of the above-mentioned processor in accordance with the control program stored in the memory unit 8.

The character recognition unit 102 recognizes characters contained in the document image obtained by document reading by the document reading unit 5. For example, the character recognition unit 102 performs character recognition processing on the document image using existing OCR (Optical Character Recognition) technology.

The page number detection unit 103 detects the page number present in a predetermined header area or footer area in the document image. For example, the page number detection unit 103 detects the page number present in the header area or footer area of the document image based on the characters recognized by the character recognition unit 102. The page number is a predetermined character string such as "page n" or "-n-".

The control unit 100 sets the value indicated by the number contained in the page number detected by the page number detection unit 103 (the value indicated by "n" in the above example) as the page number for the document image.

Next, an example of the process for setting the number of copies to be printed for each document image in the image forming device 1 according to the further embodiment will be described with reference to the flowchart shown in FIG. 9.

When the operation unit 47 receives an instruction from the user to execute document reading, the control unit 100 controls the document feed unit 6 and the document reading unit 5 to read images of multiple documents placed on the document placement tray 61 (S11).

Then, the page number detection unit 103 detects the page number present in the header area or footer area of each document image obtained by document reading by the document reading unit 5 (S12). The control unit 100 determines whether the page number detection unit 103 has detected the page number (S13).

If the control unit 100 determines that the page number detection unit 103 has detected page numbers for all document images (YES in S13), the setting unit 101 assigns and sets the page numbers detected by the page number detection unit 103 to each document image (S14).

If the control unit 100 determines that the page number detection unit 103 has not been able to detect page numbers for all of the document images (NO in S13), the setting unit 101 assigns page numbers to each document image in the order in which the documents were read by the document reading unit 5 (S15).

After S14 or S15, the control unit 100 then causes the display unit 473 to display an operation screen G1 such as the example shown in FIG. 3A (S16). During this display, the setting unit 101 sets the number of copies to be printed for each page number of the original image accepted by the operation unit 47 based on a user operation performed via the operation screen G1 (S17). The control unit 100 then performs a copy process to form images of each original image for the number of copies to be printed set by the setting unit 101 (S18). After this, the process ends.

For example, when five pages of a document are read in sequence by the document reading unit 5, the number of copies to be printed for each page number is set as shown in FIG. 5, and the page number detection unit 103 detects page numbers for all document images, the print result will be as shown in the example of FIG. 10(A). As shown in FIG. 10(A), two copies are printed for the document image for which "page 5" is detected as the page number.

When the page number detection unit 103 detects page numbers for some of the original images but does not detect page numbers for the remaining original images, the setting unit 101 may set the detected page numbers for each original image for which the page number detection unit 103 has detected a page number, and may not set page numbers for each original image for which the page number detection unit 103 has not detected a page number. In this case, the setting unit 101 sets the default value as the number of copies to be printed for each original image for which the page number has not been set (an example is shown in FIG. 10(B)).

Alternatively, when the control unit 100 is displaying the operation screen G1 on the display unit 473, if a predetermined symbol indicating an "unknown page number", for example "x", is accepted as a page number by the operation unit 47 as a result of a user operation performed via the operation screen G1, the setting unit 101 sets the value input to the operation unit 47 as the number of copies to be printed for the document image with the page number of "x" as the page number for each document image for which a page number has not been set.

According to the process for setting the number of copies to be printed for each document image in the image forming device 1 of the second embodiment, the page numbers shown in the document images are used, so the page numbers of each document image are set in the document reading order, so that the number of copies to be printed for each page can be set according to the original page numbers of the documents, even if the documents are not arranged in page number order and placed on the document placement tray 61 as in the above case, and this simplifies the operation of setting the number of copies to be printed for each page.

As a further embodiment of the process for setting the number of copies to be printed for each document image, the control unit 100 may display an operation screen G2 as shown in FIG. 11 on the display unit 473, and determine whether or not to use the page number detected by the page number detection unit 103 when setting the number of copies to be printed for each document image, according to an instruction from the user.

Radio buttons RB1 and RB2 are displayed on the operation screen G2 shown in FIG. 11. Radio button RB1 is for accepting a use instruction that selects the use of page numbers. Radio button RB2 is for accepting a non-use instruction that selects the non-use of page numbers.

When the user operates radio button RB1 and a use instruction is received by the operation unit 47 via the touch panel, the control unit 100 executes the print copy number setting process for each document image shown in FIG. 6, and when the user operates radio button RB2 and a non-use instruction is received by the operation unit 47 via the touch panel, the control unit 100 executes the print copy number setting process shown in FIG. 9.

As yet another embodiment of the process for setting the number of copies to be printed for each original image, the control unit 100 causes the display unit 473 to display a preview of each original image obtained by reading the original, and also causes the display unit 473 to display a message requesting the user to assign a page number to each displayed original image. After this display, the setting unit 101 may set the number of copies to be printed for each original image using the number of copies to be printed for each page input to the operation unit 47 by the user, in accordance with the page number for each original image input to the operation unit 47 by the user's operation.

Figure 12 is a functional block diagram that shows an outline of the main internal configuration of an image forming device 1 according to yet another embodiment. Descriptions of configurations similar to those of the image forming device 1 according to the first embodiment and the other embodiments described above will be omitted.

In the image forming device 1 according to this further embodiment, the control unit 10 functions as a table of contents detection unit 104 and an extraction unit 105 in addition to the control unit 100, setting unit 101, character recognition unit 102 and page number detection unit 103, by the operation of the processor in accordance with the control program stored in the memory unit 8.

The table of contents detection unit 104 detects an original image on which a table of contents is written. For example, the table of contents detection unit 104 detects an original image on which a table of contents is written based on characters recognized by the character recognition unit 102. Examples of predetermined character strings indicating a table of contents include "Table of Contents" or "Table of Contents".

Figure 13 is a diagram showing an example of a document D1 on which a table of contents is written. When the document D1 shown in Figure 13 is read by the document reading unit 5, the document image of the document D1 contains "Table of Contents" as a predetermined character string, and therefore the table of contents detection unit 104 detects the document image as a document image on which a table of contents is written.

The extraction unit 105 extracts the headings constituting the table of contents and the page numbers linked to the headings from the document image in which the table of contents detected by the table of contents detection unit 104 is written. The headings are, for example, composed of predetermined character symbols, such as "1.", "2.", ..., and character strings that follow them consecutively on the same line. In the example shown in FIG. 13, the extraction unit 105 extracts "1. Introduction", "2. OSS management Policy", etc. as headings. The page number linked to the heading is, for example, a number that exists at a predetermined position on the same line as the heading. The predetermined position is, for example, the end of the same line as the heading, where a space is placed between the number and the consecutive character strings. In the example shown in FIG. 13, the extraction unit 105 extracts "1" that is placed at the end of the line following "1. Introduction" as one of the page numbers linked to the heading.

For example, a heading may consist of predetermined character symbols such as "1.1", "1.2" ... and subsequent characters on the same line. In this case, the page number linked to the heading is, for example, a number located at a predetermined position on the same line as the heading. In the example shown in FIG. 13, the extraction unit 105 extracts the "1" located at the end of the line following "1.1 Purpose" as one of the page numbers linked to the heading.

For each document image obtained by document reading by the document reading unit 5, the setting unit 101 sets the page number as described in each of the above embodiments.

As shown in the example of FIG. 14(A), the control unit 100 causes the display unit 473 to display an operation screen G3 showing a list L1 created using all the headings extracted by the extraction unit 105 and the page numbers linked to the headings. The headings and the page numbers linked to the headings that make up the list L1 are displayed as text icons.

The control unit 100 also displays a message on the operation screen G3 requesting the user to select a heading. After the operation screen G3 is displayed, the setting unit 101 accepts the page associated with the heading selected by the user, which has been accepted by the operation unit 47, as the page for which the number of copies to be printed is to be set.

In the example shown in FIG. 14(A), a message M1 stating "Please select the heading for which you want to set the number of copies" is displayed on the operation screen G3. FIG. 14(B) shows a state in which three text icons have been selected by the user, including a text icon marked "3.2 System Configuration 12." "3.2 System Configuration" is the heading, and "12" is the page number associated with that heading. Note that the selection of a text icon is performed by the user touching the display portion of the desired text icon on the operation screen G3, and a selection instruction to select the text icon displayed at the touched position is input to the operation unit 47 via the touch panel, and the setting unit 101 accepts the input selection instruction.

Furthermore, an operation button B3 marked "Next" is formed on the operation screen G3. When the user touches the operation button B3 and the operation unit 47 accepts the input of a selection confirmation instruction associated with the operation button B3, the control unit 100 causes the display unit 473 to display an operation screen G4 such as the example shown in FIG. 15(A). The operation screen G4 is a screen for accepting from the user a setting for the number of copies to be printed for the page (original image) corresponding to the heading selected by the user. The operation screen G4 is provided with a text box BX3 for displaying text (character string) input by the user.

Text box BX3 displays a number that is the value of the number of copies to be printed of the manuscript image corresponding to the page of the heading selected by the user. To the left of text box BX3, the heading selected by the user and the page number (page range) of the manuscript image corresponding to that heading are displayed. For example, the page numbers "Page 12" and "Page 16" are displayed for the pages of the manuscript image corresponding to the headings "3.2..." and "4.2...", and the page range "Page 14-15" is displayed for the pages of the manuscript image corresponding to the heading "4.1...".

A method for determining the page range of a document image corresponding to a heading will be described. The setting unit 101 determines the page range of a document image corresponding to a heading to be the range from the page number linked to the heading to the page number one page before the page number linked to the next heading. From the document D1 (table of contents) shown in FIG. 13, the page corresponding to the heading "4.1 ..." is "14" and the page corresponding to the heading "4.2 ..." is "16", so the setting unit 101 sets the page range "Page 14-15" as the document image corresponding to "4.1 ...". In other words, since the page number linked to the heading "4.1 ..." is "14" and the page number linked to the next heading "4.2 ..." is "16", the setting unit 101 determines the page range of the document image corresponding to the heading "4.1 ..." to be the range up to "15", one page before "16".

Figure 15 (B) shows a state in which "5", "2", and "2" are displayed in text boxes BX3. Operation screen G4 shown in Figure 15 (B) shows a state in which the number of copies to be printed for the original image on page 12 has been specified as 5 copies, the number of copies to be printed for the original images on pages 14 and 15 has been specified as 2 copies, and the number of copies to be printed for the original image on page 16 has been specified as 2 copies, through the user's operation of operation unit 47.

Also, on the operation screen G4, an operation button B2 marked "OK" is displayed. When the user touches the operation button B2 and the operation unit 47 accepts an instruction to set the number of copies to be printed corresponding to the operation button B2, the setting unit 101 sets the number of copies to be printed for each original image for each page number or page range of the original image in accordance with the content displayed on the operation screen G4 (the content accepted by the operation unit 47). For original images of pages for which the number of copies to be printed was not specified via the operation screen G4, the setting unit 101 sets the default value (usually 1 copy).

In addition, radio buttons RB1 and RB2 are formed on the operation screen G4. Radio button RB1 is for accepting the selection of using page numbers when executing the customization process, and radio button RB2 is for accepting the selection of not using page numbers when executing the customization process.

When radio button RB1 is selected by the user, the control unit 100 executes the process for setting the number of copies to be printed for each document image shown in FIG. 6, and when radio button RB2 is operated by the user and an instruction not to use is received by the operation unit 47 via the touch panel, the control unit 100 executes the process for setting the number of copies to be printed shown in FIG. 9.

According to this embodiment, the number of copies to be printed for each document image can be set based on the document's heading, allowing the user to determine the number of copies to be printed based on the contents of the document, improving convenience when determining the number of copies to be printed.
