SOLUTION: An allocation condition is set at copying of color parts in a batch (step 302). An original having color parts and black and white parts is successively read (step 306), and only the color parts are cut out from the original and stored in a memory (step 308). A copy control table is produced, based on information of the color parts stored in the memory (step 310) and the original is copied in black and white (step 312). The color parts stored in the memory are allocated at a print position on a recording paper, based on data written in the copy control table (step 318), and the color parts are collectively copied (step 320).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing apparatus, and more particularly to an image reproducing apparatus effective for copying a plurality of originals including a color portion and a black and white portion.

[0002]

2. Description of the Related Art Conventionally, an image reproducing apparatus having both black-and-white copying and color copying functions has been known.
This image reproducing apparatus includes four color toners of cyan, magenta, yellow, and black. The original is copied in black and white using only black ink, and the original is combined by using the four color toners. Can be copied in color. The user can select whether to make a black-and-white copy or a color copy by using the mode switch of the image reproducing device or by automatically determining whether the document is a black-and-white document or a color document when the document is scanned by the image reproducing device.
(Auto Color Selection) section. In either case, only the alternative of copying in black and white or copying in color is possible.

In the case of a color copy, the photosensitive drum is rotated four times to fix the four color toners on the recording sheet, whereas in the case of a black and white copy, the photosensitive drum is rotated one time and only one color of black toner is used. Is fixed on the recording sheet. Therefore, black-and-white copying can be copied in a shorter time than color copying, and the amount of toner used is smaller.
For this reason, the usage fee of the image reproducing device in the copy service is set higher in the color copy than in the black and white copy.
A black-and-white copy is set at a charge of 10 yen per sheet.

[0004]

However, according to the conventional image reproducing apparatus, when a document includes both a color portion and a monochrome portion, especially when the area occupying the color portion in the document is small. However, it is not possible to copy only that part in color, so that there is a problem that the area must be copied in color even though the area occupied by the black and white part is large. This is because, in the case of color copying, the photosensitive drum rotates four times as compared with the case of monochrome copying, so that even if it is simply calculated, four times the time and the amount of toner are required, which is inefficient and economically inferior. Will be. For example, 250 yen is required for five color copies of a document including a color portion and a monochrome portion, and 50 yen for a monochrome copy.

[0005] A user of the image reproducing apparatus makes a black-and-white copy of a document obtained by cutting out only a color portion of a plurality of documents,
In some cases, by collecting the cut color portions and performing color copying, the number of color copies is reduced to reduce the usage fee. This method cannot be used when the original cannot be cut out, and even if it can be cut out, it is a manual operation and the efficiency is reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a method for copying a plurality of originals in which a color portion and a black-and-white portion are mixed, when the number of rotations of a photosensitive drum is increased. It is an object of the present invention to provide an image reproducing apparatus in which the copy speed is increased by reducing the number of copies and the copy fee is reduced.

The liquid crystal touch panel 330 is provided with a pressure sensor made of a transparent member divided in a matrix on the liquid crystal display. The liquid crystal display presents information to the user by the liquid crystal display and allows the user to display information on the liquid crystal display. Data input is possible by touching with a finger.

The mode setting process (step 302 in FIG. 2) will be described below with reference to the flowchart in FIG.

(Step 350) In step 350,
It is determined whether the user has selected the copy fee reduction mode. The selection of the copy fee reduction mode is performed by the user pressing the copy fee reduction key 339 on the operation panel. If the copy fee reduction mode has not been selected, the process proceeds to step 365 and the mode setting process ends. If the copy fee reduction mode has been selected, the process proceeds to step 351.

(Steps 351 to 358) In steps 351 to 358, what kind of processing is performed on a color portion in the original when the original is copied in black and white is determined. A color part monochrome copy setting screen is displayed on the liquid crystal touch panel 330 of the operation panel. FIG. 5 is a diagram showing a color part monochrome copy setting screen. The color part monochrome copy setting screen 370 includes display parts 371 to 374, and the user can select a mode by touching one of the display parts 371 to 374 with a finger.
Here, each mode will be described.

FIGS. 6A to 6E are diagrams schematically showing a state in which a color original is copied in black and white. FIG. 6A shows a state in which a color original is subjected to black-and-white copying without any processing, and a pattern represented in color in a color original is represented as black shades as it is. FIG. 6B shows a black-and-white copy state when the display portion 371 of “color portion light copy” is selected on the color portion monochrome copy setting screen 370. In this mode, the read document is printed with the brightness lowered by a predetermined amount, so that the color portion in the document is copied light and black and white as shown in the figure.

FIG. 6C shows a black-and-white copy state when the "numbered mode" display portion 372 is selected on the color portion black-and-white copy setting screen 370. In this mode, the color portion of the document is not copied in black and white, but the number assigned to the color portion is copied instead. FIG. 6D shows a black-and-white copy state when the “edge copy mode” display portion 373 is selected on the color portion black-and-white copy setting screen 370. In this mode, only the portion where the brightness changes rapidly from the read color document information is copied in black and white, so that the pattern in the color document is represented as an outline.

FIG. 6 (e) shows a black-and-white copy state when the "OHP mode" display portion 374 is selected on the color portion black-and-white copy setting screen 370. In this mode, the color portion is not copied and is represented as a blank sheet.

Returning to FIG. 3, in steps 351 to 354, it is determined which display 371 to 374 has been selected on the color part black-and-white copy setting screen 370, and the process proceeds to one of steps 355 to 358, respectively. The black and white copy mode is set.

(Steps 359 to 364) In steps 359 to 364, a process of allocating to a recording sheet when printing a plurality of color sections collectively is selected. FIG. 7 shows a selection screen of the allocation processing. The user touches any of the display portions 376 to 378 of the allocation processing selection screen 375 with a finger to select the allocation processing. When the display section 391 of “do not copy color section” is touched, the process proceeds from step 359 to step 362, and the screen shown in FIG. When the user touches the display section 380 of “Yes” with a finger, the mode is set to a mode in which data of the color section is stored as electronic data. When the user touches the display section 382 of “No” with a finger, the mode is stored as electronic data. Is set to the mode that is not performed.

When the user touches the display portion 377 of "Copy out-of-size image to another size" on the selection screen 375 of the allocation process with a finger, the process proceeds from step 360 to step 363, and the liquid crystal touch panel 330 displays the drawing shown in FIG. Is displayed. Here, the mode for copying the protruding image to another size is, for example, when three color portions A, B, and C are collectively color-copied, A4 size paper is buried in the A and B color portions. If the color portion (extended image) cannot be color-copied on the same sheet, the size of the recording sheet is increased to select whether or not the color portions A, B, and C are to be recorded on the same recording sheet.

When the user touches the display section 384 of "Yes" with a finger on the display screen shown in FIG. 9, the A3 size recording sheet is printed on the last recording sheet (the last sheet for copying the color sections collectively). Is assigned. If the finger touches the display section 386 indicating “NO”, a large-size recording sheet is not selected as the last recording sheet.

When the user touches the display portion 378 of "color copy of the protruding image" on the selection screen 375 of the layout processing with a finger, the process proceeds from step 361 to step 364, and the original including the protruding color portion is copied in black and white. Instead, the mode is set to color copy.

[Step 304] In step 304,
It is determined whether or not the start key on the operation panel has been pressed, and a standby state is established until the print key 336 on the operation panel is pressed. If the print key 336 has been pressed, the process proceeds to step 306.

[Step 306] In step 306,
The document on the document table 31 is exchanged by an automatic document feeder (hereinafter referred to as ADF). If there is no document on the document table 31, the first document is supplied by the ADF.

[Step 308] In step 308,
The red (R), green (G), and blue (B) components of the full-color information obtained by reading the original with the scanner unit 30 are processed by the image processing unit 10,
Information of the color part is stored in the memory.

Here, the color portion cutting process will be described in detail. FIG. 10 is a block diagram illustrating a schematic configuration of the color portion detection unit of the image processing unit 10. The color part detection unit 100 includes a minimum value circuit 102 and a maximum value circuit 104.
, Subtraction circuit 106, comparator 108, CPU 101
And a RAM 110.

Red (R), green (G), and blue (B) of full-color information sent from the scanner unit 30
The components are input to the minimum value circuit 102 and the maximum value circuit 104. The minimum value circuit 102 and the maximum value circuit 104 detect the maximum value (A) and the minimum value (B) of the input R, G, and B data, and the subtraction circuit 106 calculates the difference (A−B) between them. Ask. Then, the comparator 108 compares the difference (P) between the maximum value (A) and the minimum value (B) with a predetermined level (Q) sent from the CPU, and determines that the difference is larger than the predetermined level. (P> Q), the R, G, and B data are stored in the RAM 110 according to the instruction of the CPU 101. R,
A large difference between the maximum value and the minimum value of the G and B data indicates that the document data is chromatic.

On the other hand, a timing signal is supplied to the CPU 101 from a timing circuit (not shown).
When the G and B data are stored in the RAM 110, R,
The coordinate positions of the G and B data are also stored. The coordinate position indicates a coordinate point on a coordinate system with the origin at the upper left of the document. Therefore, the RAM 110 stores the coordinate position of the chromatic color pixel and the R, G, B data.

As described above, data processing is performed by the image processing unit 10 based on the data read by the scanner unit 30, so that only the color portion of the document is extracted and the RAM 110
To memorize.

[Step 310] In step 310,
The information of the color part necessary to allocate a plurality of color parts to the print positions on the recording sheet is created. The information of the color part is created by creating a copy control table.

FIG. 11 shows a copy control table. The copy control table includes “document number”, “position of color portion in document”, “size of color portion”, “black and white processing of color portion”, and “paper number of color copy”.
, “Color copy paper size”, and “color copy position”. In step 310, data of items of "document No.", "position of color portion in document", "size of color portion", and "monochrome processing of color portion" are created.

The item “document No.” is entered in step 308
Indicates the number of originals contained in the color portion read in step (1). "Position of color part in original"
Indicates the position of the read color portion in the document. The position in the document will be described later. The “color part size” indicates that the read color part size is 3
Classified and shown. The size of the collar will be described later. The item “color part monochrome processing” is set in the color part monochrome copy setting screen 3 in step 302 of the mode setting processing.
70 shows the process selected. Other items are not written in step 310. In FIG. 11, characters and the like are described in the items of “paper No. of color copy”, “paper size of color copy”, and “position of color copy”. It is not written and is blank.

Here, "position of color portion in original"
And "the size of the color portion" will be described. FIG.
FIG. 3A is a diagram schematically illustrating a position of a color portion in a document. A4 paper is divided into two equal parts in the horizontal direction and four in the vertical direction.
Equally divide into a total of 8 and position 1 to position 8 on each part
Is attached. For example, the position information of position 4 indicates that the sheet is located at the second position from the upper right side of the A4 sheet. FIGS. 12B to 12D show the size of the collar portion. FIG. 12B shows a case where the size is “1” and A4
1/8 the size of the paper. FIG. 12C shows a size “2”, which is a quarter of the size of A4 paper.
FIG. 12D shows the size “3”, which is half the size of A4 paper.

Returning to FIG. 11, data of each item is written in the copy control table for the color portion stored in the RAM 110 in step 308 of FIG. The first data will be described with reference to FIG.
The item of “document No.” is “1”, which indicates that the document including the color portion is the first document. Since the item of “position of color portion in original” is “1”, it indicates that the color portion is located at the uppermost position on the left side of the A4 sheet. "Color size" is "3"
Therefore, it indicates that the size is one half that of A4 paper. Since the item of “color part monochrome processing” is “light copy”, it indicates that the display part 371 of “color part light copy” is selected on the color part monochrome copy setting screen 370.

As described above, in step 380, the RAM 110
Are written in the copy control table shown in FIG. In FIG.
Data for nine color parts has been created.

[Step 312] In step 312,
The original placed on the platen 31 is copied in black and white. In this case, the color portion in the original is determined in step 3
Copying is performed according to the data of the item “black and white processing of color part” in the copy control table created in step S10. For example, when "light copy" is set in the item "black and white processing of color portion", the color portion is lightly copied as described with reference to FIG.

Step 3 of the mode setting process shown in FIG.
If the display section 378 of "color copy of the protruding image" is selected on the selection screen 375 of the layout processing in step 02, the black and white portion of the last original is not copied and the color portion and the black and white portion are combined in step 320. (See FIG. 17D).

[Step 314] In step 314,
It is determined whether or not there is a standby document in the ADF. If there is no standby document, the process proceeds to step 316. If there is a standby document, the process proceeds to step 306 to repeat the process up to step 312.

[Step 316] In step 316,
A determination is made as to whether the color portion is to be stored as electronic data in the memory, or whether or not the color portion is to be allocated for color copying. This determination is made when the display section 376 of “do not copy the color part” is selected on the selection screen 375 of the allocation processing in the step 302 of the mode setting processing, and the display of “Yes” on the display screen shown in FIG. The determination is made based on which of the section 380 and the display section 382 of “No” is selected. "Yes" display section 380
Is selected, the process proceeds to step 322. If the display portion 382 of "not available" is selected, the process proceeds to step 322.
Proceed to 18.

[Step 322] In step 316,
The data of the color part stored in the RAM 110 is stored as electronic data. The storage as electronic data is, for example, a form in which data of a color unit is transferred to a personal computer or the like connected to an image reproducing apparatus and stored.

[Step 318] In step 318,
An allocation process of allocating a plurality of color units stored in the RAM 110 to print positions on a recording sheet is performed. In the layout process, data of each color part is created for the items of “color copy paper No.”, “color copy paper size”, and “color copy position” in the copy control table shown in FIG. .

FIGS. 13 to 15 are flowcharts showing the flow of the allocation process. Hereinafter, the assignment processing will be described with reference to FIGS. In the layout process, the color portions are sequentially allocated to the recording sheets in descending order. First, the data of the color part is sequentially searched from the copy control table from the top (step 401). Then, data of the color portion corresponding to “3” of the “color portion size” is extracted (step 402), and “color copy paper No.” is set (step 403). "Color copy paper N
o. Is "1". And the count value cnt
Is added to 4 to determine whether or not the count value cnt has reached 8 (step 404). The reason why 4 is added to the count value cnt is that the size of the color portion is "3", which is four times the size "1".

If the count value cnt is not 8, "1" is set in the "color copy position" (step 40).
5). When the count value cnt reaches 8, “5” is set in the “color copy position” (step 406),
The count value cnt is set to 0, and the paper No.
Is incremented, and a new paper number is set (step 407).

Here, at step 404, the count value cn
When t becomes 4, the upper half of the sheet is assigned, and when the count value cnt becomes 8, it means that the color portion is assigned to all of the sheets.

In step 408, it is determined whether or not there is data in the color portion corresponding to "color portion size" of "3" in the copy control table shown in FIG. The processing from step 402 to step 408 is repeated until there is no corresponding data, and the process proceeds to step 411.

Next, the data of the color portion is searched sequentially from the top of the copy control table shown in FIG. 11 (step 4).
11) Data whose “color portion size” is “2” is selected (step 412). The item of “color copy paper No.” is set in order from the selected data (step 413), and it is determined whether 2 is added to the count value cnt and the count value cnt has reached 8 (step 413). Step 414). Here, the count value cnt is 2
Is added because the size “2” is twice the size “1”.

If the count value cnt has not reached 8 and the count value cnt is 2, "1" is set in the "color copy position" (step 416).
If the count value cnt is 4, "2" is set in the "color copy position" (step 418), and if the count value cnt is not 4, "5" is set in the "color copy position". Is performed (step 419). If the count value cnt is 8 in step 414, "6" is set in the "color copy position" (step 420), and the count value cnt is set to 0.
Is incremented, and a new sheet number is set (step 421).

Then, in step 422, it is determined whether or not there is data in the copy control table corresponding to "color part size" of "2". If there is such data, the processing in steps 412 to 422 is performed. The process is repeated, and if there is no corresponding data, the process proceeds to step 431.

Next, the data of the color portion of the copy control table shown in FIG. 11 is sequentially searched from the top (step 43).
1) The data corresponding to “1” in the “color part size” is selected (step 432). "Color copy paper No." is set in the data of the color portion (step 4).
33) It is determined whether or not the count value cnt is incremented by 1 and the count value cnt reaches 8 (step 434).

If the count value cnt has not reached 8, the value of the count value cnt is set in the "color copy position" (step 435). Count value cnt is 8
In the case of No., "8" is set in the "color copy position" (step 436), 0 is set in the count value cnt, and the paper No. Is set (step 437). Then, it is searched whether or not the data of the color part of the copy control table includes data corresponding to “color part size” of “1”.
The processing from step 2 to step 438 is repeated, and if there is no corresponding data, the process proceeds to step 439.

At step 439, the count value cnt is set to 0.
A determination is made as to whether the If the count value cnt is 0, that is, if the color portions have been allocated to all the recording sheets, the process proceeds to step 442, and the allocation process ends. If the count value cnt is not 0, that is, if the color portion is allocated halfway through the last recording sheet,
Proceeding to step 440, it is determined whether or not to copy on A3 paper. The determination as to whether or not to copy on A3 paper is made on the selection screen 3 of the allocation processing in step 302 of the mode setting processing.
Display part 37 of “copy outsized image to another size” at 75
7 is selected, and the display section 38 of "Yes" is displayed on the screen shown in FIG.
The determination is made based on which of the display unit 386 of “4” and “No” is selected.

The display section 384 of "Yes" on the display screen of FIG.
If is selected, the process proceeds to step 441, where "color copy paper N"
o. Is the last paper number,
1 and 8 is added to "position of color copy". As a result, the color portion assigned to the last page number is assigned to the immediately preceding page, and has a value obtained by adding 8 to the "color copy position", and is assigned to the right half position of the A3 sheet. Will be. FIG. 16 shows the “color copy position” of the A3 sheet.

FIG. 11 shows an example in which a color control section is allocated to create a copy control table based on the allocation processing described above. Manuscript No. Of the nine color sections included in the original Nos. The color portions included in the originals 1 and 5 are collectively allocated to A4 size paper with “color copy paper No.” being “1”, and the color portions included in other originals are “color copy paper No. Is assigned to a sheet of A3 size at "2". Therefore, the nine color sections are printed together on two sheets.

[Step 320] In step 320,
According to the data in the copy control table shown in FIG.

The state where the color portion E is copied at the top of page 8 is shown. FIG. 17C shows a selection screen 375 of the allocation processing.
This shows an output state when the display unit 377 of “copy of the protruding image to another size” is selected and the display unit 384 of “Yes” is selected on the display screen of FIG. Pages 1 to 5 are copied in black and white, color portion A and color portion B are copied on page 6, and color portion C and color portion D are copied on page 7 using A3 paper.
And a color portion E are color-copied. FIG.
FIG. 7D illustrates a copy output state when the display section 378 of “color copy of the protruding image” is selected on the allocation processing selection screen 375. Pages 1 to 4 are copied in black and white, page 5 is copied in color including color portion E,
In the page, the color portion A and the color portion B are color-copied.
In the page, a color portion C and a color portion D are color-copied.

Step 3 of the mode setting process shown in FIG.
02, the "numbered mode" is displayed on the display screen of FIG.
When the display section 372 is selected, the number assigned at the time of black-and-white copying is assigned near the color section to perform color copying.

As described above, according to the image reproducing apparatus of the present embodiment, when copying a plurality of originals having a color portion and a monochrome portion in the copy fee reduction mode,
Since the number of times of color copying is reduced, the copying fee can be significantly reduced. For example, black and white copy 1
In the case of 10 yen per sheet and 50 yen per color copy, if the original shown in FIG. 17A is copied in the normal mode, 250 yen is required, but in the mode shown in FIG. In this case, a total of 200 yen including 50 yen for a black-and-white copy and 150 yen for a color copy. FIG. 17 (c)
17 is a total of 150 yen including 50 yen for a black-and-white copy and 100 yen for a color copy.
When copying in the mode of (d), a monochrome copy 40
A total of 190 yen for a yen and a color copy of 150 yen. Thus, the copy fee can be significantly reduced. Further, the user cuts out the original, and the user cuts out the original as shown in FIGS.
(D) can be output as a copy,
In the image reproducing apparatus shown in the present embodiment, all the cutting and pasting operations are performed automatically, so that the user can save time and effort.

Further, a color part monochrome copy setting screen 37 is displayed.
At 0, set a mode to copy the color part lightly, a mode to copy with a number without copying the color part, a mode to copy the color part with edge processing, and an OHP mode to not copy the color part. Since the black-and-white copy is performed so that the color portion is not conspicuous, when the color portion is later cut out and pasted on the black-and-white copied paper, the color portion cut and pasted through the base does not become difficult to see.

In this embodiment, a plurality of originals are copied in black and white and then copied in color. However, after all the data read by the scanner unit 30 is stored in the image memory, the color unit is copied first. May be copied.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
