Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital copying machine that reads a document image placed on a document table and forms a document image on a sheet after image processing, and in particular, a digital copying machine that can output a plurality of document images on a single sheet. About.

2. Description of the Related Art In recent years, digital copiers that generate image data of a document image by converting image information of a document placed on a document table into an electric signal by a photoelectric conversion element such as a CCD and output the image data on paper have been becoming widespread. . According to the digital copying machine, since the original image can be handled as image information, it becomes easy to edit and output the original image.

On the other hand, due to demands for resource saving and space saving, it has been desired to edit and output a plurality of pages of a document image on one copy sheet. Therefore, for example, Patent Document 1 discloses that a four-page document is edited using a digital copying machine and output on one copy sheet.

Digital copiers having an automatic paper selection (APS) function capable of outputting documents of different sizes on paper of a predetermined size are also becoming widespread.

JP-A-3-233578

As described above, a digital copier capable of editing a four-page document and outputting the document on one copy sheet has been disclosed. However, it is only necessary to output a document on one copy sheet every four pages. The resulting copy is far from easy to read. This is because (i) a series of manuscript sets has breaks such as chapters and sections, and if chapters and sections are mixed in one copy sheet, a copy is difficult for the reader to understand.

(Ii) In a series of original sets, there is a possibility that originals having different sizes and vertical / horizontal directions are mixed. If a copy image of a portrait document and a landscape document are mixed in one copy sheet, the sheet must be rotated when reading one copy sheet, which is inconvenient.

Particularly, when a plurality of pages of a document are edited and one copy sheet is output, the document image is inevitably output in a reduced size, so it is necessary to provide a copy that is easy to read even a little.

Further, in a digital copying machine having a conventional APS function, when a plurality of documents of different sizes are copied, the paper size is frequently switched and the direction of the image is changed, so that it is difficult to align the copy paper. In addition, there is a problem that it is necessary to rearrange the information in a state that is easy for the user to see, which makes it difficult to see.

The present invention has been made to solve the above problems, and has the following objects.

(I) To output a copy image that is easy to read in a digital copying machine capable of outputting a plurality of originals on one copy sheet.

(Ii) To separate sheets according to the user's intention in a digital copying machine capable of reading images of a plurality of originals and outputting them on one copy sheet.

(Iii) In a digital copier capable of reading images of a plurality of originals and outputting them on one copy sheet, the direction of the images is fixed for each sheet.

(Iv) An object of the present invention is to provide a digital copying machine capable of forming a plurality of images in an optimal form on the same copy paper.

(V) An object of the present invention is to provide a digital copying machine capable of forming an image on a copy sheet of the same size from a plurality of documents having an arbitrary size and orientation in a viewable state.

The present invention relates to a digital copying machine capable of reading images of a plurality of documents, editing the read images on a single copy sheet at predetermined intervals, and outputting the edited images, wherein a partition set between the plurality of documents is provided. Detecting means for detecting a sheet, an image memory having a plurality of pages of storage areas corresponding to the copy paper for a plurality of pages, and expanding the read image by one for each page of the image memory. Control means for controlling, when the detection means detects the partition paper, the number of images of the original document developed in the image memory for one page has reached the predetermined number. Even when there is no document, the page of the image memory where the image of the document should be developed is switched to the next page.

According to the digital copying machine of the present invention, when a partition sheet is detected, even if the number of original images developed in the image memory for one page does not reach a predetermined number, the original image is developed. The page of the image memory to be changed is switched to the next page. For this reason, even when the read image is edited and output on one copy paper every predetermined number, the insertion of the partition paper allows the user to output the desired image in a desired output form, for example, a chapter or a section. Copy paper can be output separately.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(1) First Embodiment FIG. 1 is a diagram showing an internal configuration of a digital copying machine.

And a motor M2. The scanners 11 and 14 are driven by the motor M2 and move in the direction of arrow b (sub-scanning direction) directly below the platen glass 19, respectively. With this movement, the image of the document set on the platen glass 19 is read by the line sensor 17. The line sensor 17 has a number of elements (CCDs) arranged in a direction orthogonal to the sub-scanning direction b, and this juxtaposed direction is referred to as a main scanning direction.

The image data processing unit 20 and the memory unit 30 will be described later in detail. The print processing unit 40 drives the optical system 60 line by line in the main scanning direction based on the print data. The optical system 60 includes a semiconductor laser 61 modulated (on / off) controlled by the print processing unit 40, a polygon mirror 62 for deflecting and scanning the laser beam emitted from the semiconductor laser 61, and a distortion of the deflected laser beam.

The originals placed on the tray 501 are conveyed one by one from the lowermost one onto the platen glass 19 and stopped there. The image of the original is read by the reading system 10. After the reading is completed, the original is distributed on a discharge tray 508 via a reversing roller 507. In the case of a two-sided original, the original is returned to the platen glass 19 by making one rotation around the reversing roller 507. Therefore, the transport belt 506 can rotate forward and backward. The size and direction of the document are detected just before being sent onto the platen glass 19 by the ON time of the sensor SE5. The sensor SE5 also detects a partition sheet 100 described later. A sensor SE4 for detecting the presence or absence of a document is provided on the tray 501.

In the copying machine having the above-described configuration, in the normal mode, an image of one document is read, the image data is subjected to necessary correction, print data is generated, and the print data is output by the optical system 60. An image is formed on the copy paper of the above. In addition to this, processing can be performed by selecting the 4-in-1 mode. In the 4-in-1 mode, each time a document image is read, the document image is sequentially developed in a quarter of the image memory 31 for one copy sheet. However, when the partition paper 100 is detected, or when the vertical / horizontal orientation of the original is switched, even if the original image undeveloped area remains on the image memory 31, the image memory corresponding to the next output copy paper The original image is developed on the reference numeral 32.

Next, the control of the copying machine will be described. FIG. 2 shows a portion related to the present invention in the control block diagram of the digital copying machine. The image data processing unit 20 includes a CPU 21 with a built-in program memory for performing timing control of the entire apparatus, an A / D converter 22, a shading correction unit 23, a gradation correction unit 24, a scaling unit 25, a binarization unit 26, It is constituted by an address decoder 27. An image reading synchronization signal is supplied from the CPU 21 to the line sensor 17, the image data processing unit 20, the memory unit 30, and the print processing unit 40.

The signal read line by line by the line sensor 17 is analog data, and the analog data is converted into digital image data of 8-bit gradation per pixel by the A / D converter 22, and shading correction, MTF correction, Known image processing such as gradation correction such as γ correction and zooming is performed. In the binarization processing unit 26, after the image data is converted into binary data by the error diffusion method, the image data is stored at a specific address of the memory unit 30 designated by the address decoder 27.

The image data written in the memory unit 30 is transferred to the print processing unit 40 according to an instruction from the CPU 21. Here, after the D / A conversion by the D / A converter 41, the semiconductor laser 61 is driven based on the image data that has been D / A converted by the LD driver 42.

{Circle around (5)} The CPU 21 controls the input and display of signals from the respective scan keys on the operation panel 90. The operation panel is configured as shown in FIG.

Referring to FIG. 3, operation panel 90 includes numeric keypad 900 for setting the number of copies. The set number is displayed on the number display section 901. The copy magnification is selected with the select key 902 from the copy magnification displayed on the magnification display section 903. Each time the selection key 902 is pressed, the selected magnification is switched.

The paper size is the copy paper size set in the automatic paper feed cassettes 81a and 81b displayed on the paper size display section (the copy paper size set in the automatic paper feed cassettes 81a and 81b and the copy paper size not set in the automatic paper feed cassettes 81a and 81b). Are displayed using the copy paper size selection key 904. Each time the key 904 is pressed, the selected copy paper size is switched.

A key 906 is provided for selecting an automatic paper selection (APS) and automatic magnification selection (AMS) mode and a manual (manual) mode in which paper selection and magnification selection are manually performed. Each time the key 906 is pressed, the selected mode is switched, and the display lamp 907 is turned on accordingly. The selection of the 4-in-1 mode for copying four document images on one copy sheet is performed with the selection key 910. When this mode is set, the display lamp 911 is turned on. When the 4in1 mode is selected, the automatic magnification selection mode is set regardless of the selection of the key 906.

(5) When the setting of various modes is completed and a copy start button 916 is pressed, a series of copy operations is started.

Next, the memory unit 30 will be described. The memory unit has a capacity capable of storing 50 pages of A3 size documents. FIG. 4 shows one page of the image memory 31 therein. The image memory 31 is configured to have a two-dimensional address corresponding to one A3-size copy sheet. It has an X address in the sub-scanning direction and a Y address in the main scanning direction. X is set from 1 to 4X0, and Y is set from 1 to 2Y0. A similar image memory is provided for 49 pages.

FIG. 5 is a diagram showing a relationship between a document and a copy image on copy paper when the 4-in-1 mode is set. (A) shows the orientation and size of the original, (b) shows the specific arrangement on the copy paper, and (c) shows the copy paper and the address on the image memory when the original is placed horizontally and vertically. FIG.

With reference to FIG. 5, according to the digital copying machine, when the original set is separated by the partition paper 100 in the middle of the original as shown in FIG. The output is as shown in b). In the figures, (a) and (b) illustrate the case where the A4 size is selected as the copy paper, p indicates the page order of the original, n indicates the page order of the copy paper, and n indicates the page order of the image memory. Corresponds one-to-one. For example, n = 1 corresponds to the image memory 31, and n = 2 corresponds to the image memory 32. n indicates the arrangement position of the image document on the copy paper. Here, with respect to the length and width of the original, a case where the long side of the original is set in parallel with the main scanning direction is defined as a horizontal orientation, and the opposite is defined as a vertical orientation. In FIGS. 7A and 7B, the size of the copy paper in FIG. 5B is four times larger than that in FIG.

FIG. 6 is a flowchart showing a processing procedure of the CPU 21 for executing the above control. Referring to FIG. 6, if a copy start button 916 is pressed, an initial setting process is performed in # 60, the image memory of memory unit 30 is cleared, and both variables n and m are set to 0. The meanings of the variables n and m are the same as in FIG.

(4) In step # 61, the presence or absence of a document on the tray 501 on the platen is detected in step SE4. In step # 62, the document is conveyed. It is determined whether the paper conveyed in # 63 is a partition paper. Note that holes are provided in the partition paper 100 at locations corresponding to the detection positions by SE5 as shown in FIG. The sensor SE5 detects this hole in a short cycle and repeats ON / OFF to determine whether the sheet is a partition sheet. If it is not the partition paper 100, the copy paper size set by the copy paper size selector 904 is detected in # 64, and the magnification is determined. In this case, since the mode is the 4-in-1 mode, the copy magnification M is M = (paper size) / {2 × (document size)}.

In # 65, it is determined whether m = 4, and in # 66, it is determined whether the orientation of the document has changed. If any of the above cases is satisfied, even if an undeveloped area remains in the image memory, the page of the image memory is changed in step # 67 (m = n + 1), and m is returned to 1. If both # 65 and # 66 are NO, m is advanced by one in # 68, and if it is determined in # 69 that the paper is not the partition paper 100, the original image is read by the line sensor 17 in # 70 and written into the image memory. . Then, the process returns to step # 61 to determine whether or not reading of the document is completed. The above process is repeated until the reading is completed, and the document image is developed in the image memory for each page of the document. If there are no more documents on the tray 501 (YES in # 61), in # 71 the document images developed in the image memory are formed and output one page at a time on copy paper, and the process ends.

Next, the writing process to the image memory at # 70 will be described. FIG. 7 is a diagram for explaining this processing. (A) shows a case where the document is placed horizontally, and (b) shows a case where the document is placed vertically. Referring to FIG. 7A, in this case, since the copy paper is selected to be A4 landscape, the CPU 21 reduces the read original image in accordance with the value of the magnification M and performs parallel reduction in accordance with the value of m. After the movement, the data is written into the image memory 31. In (b), since the copy paper is placed in the A4 portrait orientation, the CPU 21 reduces the read document image according to the value of the magnification M, performs rotational movement of + 90 °, and performs parallel movement according to the value of m. Then, the data is written into the image memory 31. In other words, in # 70, the orientation of the document is determined, a linear conversion as shown in Table 1 is performed according to the direction, and the document image is developed in the image memory corresponding to the variable n.

As described above, the document image is output on the copy paper as shown in FIG. It is also possible to change the arrangement of the 4-in-1 original image as shown in FIG. Further, the switching may be appropriately performed. Furthermore, in the above embodiment, the case where N = 4 has been described, but it is also possible to set N = 2, 9, 16,... Simply by changing the address setting of the memory area. By doing so, it is possible to output a plurality of document images in a desired output form.

(2) Second Embodiment Next, a second embodiment of the present invention will be described. Also in the second embodiment, the configuration of the digital copying machine is the same as that of the first embodiment, and the description thereof will be omitted, and only different points will be described below. In the second embodiment, a setting key 920 for 2-in-1 copy in the mixed original auto mode is provided on the scanning panel 90 as shown by a dotted line in FIG. When this key is pressed, 2-in-1 copying in the mixed original auto mode described below is executed.

FIG. 10 is a diagram showing a relationship between a document and a copy sheet in 2-in-1 copy in the mixed document auto mode. In this mode, documents having different sizes and orientations are automatically copied onto one type of paper. This will be specifically described below.

As shown in FIG. 10, originals of different sizes and sizes are copied on A3 length paper, the first page is A4 width, the second page is B4 length, the third and fourth pages are A4 width, and the fifth page is A3 length. Consider the case. In this case, the copy mode is determined based on the directions and sizes of two consecutive documents. In this embodiment, since the document mixed auto mode of 2in1 copy is set, (a) when the paper size is determined in the vertical direction, and 2in1 when the originals in the horizontal direction and the same size as half of the paper size are continuous. make a copy.

(B) When originals in the horizontal direction and half the size of the paper are not continuous (b-1) In the case of originals in the horizontal direction, the magnification is automatically calculated to half the size of the paper and output .

(B-2) In the case of a document in the vertical direction, the magnification is automatically calculated based on the size of the sheet and output.

That is, in FIG. 10, (b-1) for document 1, (b-2) for document 2, (a) for documents 3 and 4, and (b- The processing of 2) is automatically selected and performed.

By performing the above processing, it is not necessary to change the copy mode every time the document size or direction changes, even if the document has a different size and direction. Further, if there is a document having the same size as half of the continuous paper size, 2-in-1 copy is performed, so that copy paper can be saved. Further, the above processing can be applied to both sides of the copy sheet.

Also, as a modified example of (b-1), even if the originals in the horizontal direction are not continuous, the 2-in-1 copy may be performed by changing the magnification to half the size of the paper when the originals in the horizontal direction are continuous.

FIG. 11A is a diagram showing the contents of a document management table created by the CPU 21 for the document shown in FIG. Processing such as scaling of a document image as shown in FIG. 10 is performed using this document management table. The paper size in this embodiment is assumed to be A3 vertical size. In this case, since the orientation of the original is different between the first page and the second page, there is no set of pages. Also, since the original direction is horizontal, the magnification for half the size of the paper is calculated to be 1.000, which is registered as additional information. Next, since the direction of the original is different between the second page and the third page, there is no set of pages. In addition, since the original direction is vertical, the magnification for the size of the entire sheet is calculated as 1.154.

Next, for the third and fourth pages, since the document size is both horizontal and the document size is equal to half the size of the sheet, the 2in1 mode can be registered. For this reason, 4 is recorded as additional information of page 3 of the third page, 3 is recorded as the page of fourth page, and 1.000 is both set as the magnification. Hereinafter, additional information is registered for all the read pages in the same manner as described above. FIG. 11B shows the relationship between the image memory and the original image in the 2-in-1 mode performed on the third and fourth pages.

Next, the processing of the CPU 21 for performing the above operation will be described. FIG. 12 is a flowchart illustrating a processing procedure of the CPU 21 according to the second embodiment. Referring to FIG. 12, first, it is determined whether or not a memory mode using memory unit 30 is set. In the 2-in-1 copy in the mixed original auto mode, the memory mode is automatically set.

場合 If the mode is the memory mode (YES in # 211), the memory operation mode is determined in # 212. If the memory write operation is set (YES in # 212), the memory write operation is performed (# 214). If the memory read operation is set (NO in # 212), the memory read operation is performed. Do. (# 217). In cases other than the memory mode (NO in # 211), the direct connection mode operation is performed (# 213). In the following description, it is assumed that the image information has already been stored in the memory unit 30 by the writing operation (# 214).

FIG. 13 is a flowchart showing a subroutine of the memory reading operation in the mixed original auto mode shown by # 217 in FIG. Here, the CPU 21 sets a decompression request command (Q) and a print request command (Q) for the image data processing unit 20 and the memory unit 30 so as to form the processing form shown in FIG. In step # 401, the process branches in steps # 403 (when "0"), # 411 (when "1"), and # 431 (when "2") according to the value of the read state.

(A) When the read state = "0" First, additional information of the document management table shown in FIG. 11 is created (# 403). Next, the variable n indicating the read page is initialized (# 405), and the read state is updated (# 407).

(B) When the read state is "1", the additional information of page n is substituted for the variable x (# 411), and when this is different from page number n (# 413), that is, two pages are printed on one sheet. In this case, (n + 1) indicating the page number is registered as a parameter in the decompression request buffer (# 415). Further, n indicating the page number is registered as another parameter in the decompression request buffer (# 417). In # 419, n ← n + 2 is set in preparation for the next reading.

When the additional information and the page number are the same (NO in # 413), since only one page of data is printed on one sheet, n is registered in the decompression request buffer and n ← n + 1 (# 421, # 422). ). Further, a print command is registered in the print request buffer (# 425). At this time, the magnification registered in the additional information is registered as a parameter. The read state is updated (# 427). The scaling unit 25 can know the page number to be expanded by the parameter of the expansion request command.

(C) If the paper feed report (A) indicating that paper has been fed from the copy paper transport system 80 when the read state is “2” (YES in # 431), all pages are read in # 433. Determine if it is completed. If not completed (YES in # 433), the process returns to the read state "1" (# 439), and the above-described processing is repeated. If completed (NO in # 433), the read state is reset (# 435), and the mode is set to the write operation mode (# 437).

FIG. 14 is a flowchart showing a subroutine for creating additional information indicated by # 403 in FIG. The additional information creating subroutine will be described with reference to FIG. First, the paper size required for calculating the magnification when performing 2in1 copying is calculated in consideration of the 2in1 mode (# 501). A page number for creating additional information is initialized (# 503). It is determined whether the p-th document direction is vertical or horizontal (# 505). Here, when the original direction is vertical (YES in # 505), since the paper size is assumed to be vertical in the present embodiment, the copy is performed without performing 2in1 copy at this time. The page is registered (# 507). Further, the magnification is calculated from the actual paper size (# 509). Since the data of one page has been registered, the page number is updated by 1 (# 511).

When the original direction is horizontal (NO in # 505), if the page number is smaller than the total number of pages (N) (YES in # 521) and the next page number (p + 1) is horizontal (YES in # 523). After # 525, additional information for 2in1 copy is registered. If either one of the above two conditions is not satisfied (NO in # 521 and # 523), the same processing as in the vertical direction is performed.

(4) When two originals are arranged in a horizontal direction (YES in # 521 and # 523), additional information for 2-in-1 copy is created. That is, a set of pages is registered for the page numbers p and p + 1 (# 525, # 527), and the magnification is similarly calculated from the paper size (# 529, # 531). Since the data of two pages has been registered, the page number is updated (# 533). The above processing is repeated for all the read originals (# 513).

In the above-described embodiment, the case where the copy paper size is A4 portrait has been described.
