Reference numeral 04 denotes a copy start instruction, and the reset key 105 is used to return various settings to the standard state.

Next, FIG. 2 shows the internal structure of the machine according to the present embodiment, which will be described. FIG. 2 is a sectional view of the device according to the present embodiment. The document reading unit 10 (hereinafter referred to as a scanner) irradiates a document on the platen glass 17 with a lens and a light source 15, and reads the reflected light from the reading element C.
Photoelectric conversion is performed by the CCD unit 16 equipped with a CD,
Convert to image signal.

The converted image signal is subjected to image processing by the control board 2 incorporating a microcomputer and transferred to the printer section 3. Reference numeral 11 is a document pressing plate.

The printer 3 reproduces the color information read by the scanner 10 on a sheet as a visible image, and the sheet can be selected from the roll sheet 29 and the cassette sheet contained in the cassette 20. .

When the start key 104 of the operation unit shown in FIG. 1 is pressed, the roll paper 29 is conveyed by the rollers 30 and is conveyed by the rollers 26 and 27 and stopped on the platen 39. Then, by moving the carriage unit 34 having the print head 37 moving on the rail 36 in the depth direction in the drawing, image information is printed on the paper. The print head 37 is an inkjet print head.
There are four heads lined up: black, yellow, magenta, and cyan.

In the present embodiment, the width that can be printed simultaneously at one time is 256 pixels (16 mm because this device has 400 pixels per inch). When one-line printing is completed, the carriage 34 returns to the front, and the paper is conveyed by the roller 28 for one line. By repeating the above operation, 1
When the image for one sheet is printed, the printed paper is discharged to the tray 23 outside the machine. It should be noted that the cutter 31 cuts the paper into a required size corresponding to the feed amount of the paper.

The ink tank 35 is for supplying ink to each print head. In the case of cut paper, it is carried out of the cassette 20 by the roller 24, conveyed by the roller 25, and printed in the same manner as the roll paper.

The roller 32 is a paper feeding roller for manual copying. The control board 2 is a scanner unit,
While controlling the copy operation of both printer units, various image processing is also performed.

Next, FIG. 3 shows the scanner 10 of the present embodiment.
The image processing unit on the control board 2 is shown and will be described below. The reading element CCD 200 is a well-known element that photoelectrically converts the reflected light from the document into color signals of RGB three colors (composed of 8 bits for each color).

An image signal read by the CCD 200 is converted into a YMC signal through an input image processing section 201 (where dark current removal, shading processing and the like are performed) and an RGB to YMC conversion circuit 202. A CPU (not shown) that controls each unit has a circuit configuration capable of reading the color information and storing the color information in the memory circuit 300 when converted into the YMC signal.

Therefore, in the case of color registration, the registration is performed by reading the YMC color information of the coordinates on the specified original and storing it in the specified memory. In the case of the registered color adjustment, the color information selected by the operator from the color information stored in the memory circuit 300 is converted by the hue conversion coefficient provided by the CPU, and then the hue data memory 3
It has a circuit configuration that can be stored in 40.

The signal converted into YMC is divided into a plain path and a color conversion circuit 205 path. The selector 204 selects whether the color conversion circuit 205 performs conversion according to the density of the input YMC or the constant density given to the register 203 by the CPU. Then, the converted color is created by multiplying the selected information by the registered color information.

Then, the image information is also input to the comparison circuit 206. The comparison circuit 206 is a circuit for comparing whether or not the density of each color of YMC is within a certain range, and the range is determined by reading the comparison color by the same method as the color registration and expanding the value according to the instruction of the operator. (For example,
If the reading is 5, then the range is determined between 4 and 6, between 3 and 7, and between 2 and 8).

If each YMC color falls within the range, a conversion signal is output. The selector 207 is a selector for validating the output of the comparison circuit 206 or performing color conversion regardless of the output of the comparison circuit 206, and the gate 208 is a gate for performing color conversion or not. The selector and gate are the CPU (controller 310).
Controlled by.

The selector 209 is for switching between the original image information and the converted image information depending on the output of the comparison circuit 206 or the like. Then, the image information is a gate 210 for whether to output an image.
Then, it passes through an output image processing circuit (black information extraction, etc.) 211, is converted into binary data by a binarizing circuit 212, and is sent to a recording unit 3 (hereinafter referred to as a printer). Gate 21
The gate signal of 0 is created by comparing the counters of the main scanning and the sub scanning.

The scanner according to the present embodiment uses a CCD
While reading 56 pixels (about 16 mm) at the same time (referred to as main scanning), the printer moves in the sub-scanning direction, and the printer similarly
Reading and printing are performed by a raster system that moves in the sub-scanning direction (Y direction in FIG. 6) while printing 6 pixels at a time (X direction in FIG. 3).

Therefore, the gate signal is also read at the same time 256
A start register 217 indicating a start pixel in the pixel direction (main scanning) and an end register 218 indicating the number of end pixels
The main scanning pixel counter 21 by the comparison circuit 220.
9, a gate signal in the main scanning direction is generated, and similarly in the sub scanning direction, a gate signal is generated by the start register 213, the end register 214, the sub scanning pixel counter 215, and the comparison circuit 216. A gate signal is input to the gate 210 via the gate.

The printer has print heads 37 capable of simultaneously printing 256 pixels in FIG. 6 for the respective colors of cyan, magenta, yellow and black.
While printing, printing is performed in the sub-scanning direction, and after printing one line, the paper is moved upward by one line and the next line is printed.

In FIG. 3, 310 is a controller (CPU) for controlling the operation of each part of the apparatus, 320 is the operation between the digitizer 16 or the operation display section 330 shown in FIG. 1 or FIGS. 8 to 11 and the controller 310.

Next, the area designation mode designated by the key 110 shown in FIG. 1 will be described. <Explanation of area designation mode> Area designation mode M300
Allows you to specify one or more areas on the document, and trimming mode M for each area.
An arbitrary mode setting can be performed among three modes, that is, 310, masking mode M320, and image separation mode. The trimming mode M310 described here is to copy only the image inside the specified region, and the masking mode M320 is to copy by copying the inside of the specified region with a white image.

Further, as the image separation mode M330, any one of the color mode M331, the color conversion mode M332, the paint mode M333, the color balance mode M334, and the free color mode M335 can be selected. In the color mode M331, four full colors, three full colors Y, M, and
An arbitrary color mode can be selected from among 9 types of C, Bk, RED, GREEN, and BLUE.

In the free color mode M335, a mono-color image in a color other than the above-mentioned seven mono-colors can be selected within the designated area. The color conversion mode M332 is a mode in which a predetermined color portion having a certain density range is replaced with another arbitrary color in a designated area and copied.

The paint mode M333 is a mode in which a copy is uniformly filled with another arbitrary color over the entire designated area. Color balance mode M334
In this mode, the density of each of Y, M, C, and Bk in the designated area is adjusted to print with a color balance (color tone) different from that of the undesignated area.

A specific operation method in this embodiment of the area designation mode M300 will be sequentially described with reference to FIG. First, when the area designation key 424 on the digitizer 16 is pressed, the liquid crystal display changes to the screen P300, and the digitizer 1

1 to 29 are stored in the hue data memory 340.
Up to 27 types are stored. As shown in FIG. 6, the color information (adjustment color) 1 stored in the hue data memory 340
.About.29 are sequentially printed out on the paper 351 in a size of 10 cm.multidot.10 cm.

The control is performed by the CPU (controller 310)
The operation is performed. The following operation will be described with reference to the flowcharts of FIGS. First, an appropriate value (this value is registered; corresponds to the density of the color when copying is performed) is set in the register 203, and the selector 20 is set.
4 is selected as the register 203 (STP401). Then, the selector 207 is constantly switched to the variable, and the gate 208
To the output selection of the selector 207 (STP402).
As described above, the selector 209 always selects the color conversion circuit 205 side. Then, the preprocessing such as the paper feeding operation of the printer is started (STP403). And work RA
Set the line number counter on M to 0 (STP40
4), 1 to color counter 1 and color counter 2 on the work RAM
Is set (STP405).

It should be noted that the value of the color counter 2 is the adjustment No. 1 shown in FIG. 1 to 29, for example, the color counter 2
If the value is 1, the adjustment No. The color data of 1 is the color conversion circuit 2
It is set to 05. In the mode for selecting the adjustment color with the ten keys in FIG. (STP801), and then No. 1-9, No. 11
-19, No. 21 to 29 (STP802), and if so, the adjustment color No. Write color data corresponding to
P803).

Returning to FIG. 4 again, next to STP405, the color information is set in the color conversion circuit 205 (STP40).
7). And because the print position on the paper is fixed,
The print position in the main scanning direction is set on the start register 217 and the end register 218 for the print position control counter (STP408) [For example, for the second color, to the start counter 1889 = {(100 + 10 + 10) / 2.
5.4} × 400, to end counter 3464 = {(1
0 + 100 + 10 + 100) /25.4} × 400].

Then, the line number counter is 6 or 13 or 2.
When it is 0 (STP409), 0 is set in the start register 213 of the comparison register of the sub-scanning counter and 38 is set in the end register 214 (STP41).
1). Start register 213 for other lines
To 0 and 256 to the end register 214 (S
TP410).

In the present embodiment, when copying the adjustment color, one of the adjustment colors is made to correspond to a square of 100 mm / 100 mm, and the 100 mm is 100 mm = (256/400) × 25.4 × 6 + (3
8/400) × 25.4 (256, 400, 38 are pixels, 25.4 is mm in 1 inch, and 6 is the number of lines), so the numerical values are set as described above. .

Incidentally, the line number counter is a counter inside the controller 310, and the line number counter is moved by one line in the Y direction of FIG. 6 by one line (in this embodiment, the print head is counted). 37 is X in FIG.
Since 256 pixels are lined up in each direction, the width of one line in the X direction corresponds to about 16 mm.) The number of times printing is performed is counted. The main scanning counter 219 counts the pulses output each time the print head 37 obtained from the printer 3 is moved by one pixel in the Y direction, and is reset each time printing for one line is completed.

The sub-scanning counter is a counter that is reset every time one line in the sub-scanning direction of the print head 37 is printed, and counts the pulse indicating the print timing supplied to the print head 37.

In STP412, by reading and printing, the main scanning and sub-scanning counters are operated to print color information on the paper. Then, the color counter 2 is incremented by 1 (STP413). In this embodiment, nine pixels are arranged side by side, so the above operation is repeated until the color counter reaches 9, 19 or 29 (STP414). When printing for one line is completed, the printer conveys the paper for one line (S
TP415), and the line number counter is increased (STP4
16), if the line number counter reaches 21, (STP41
7) The CCD unit 16 of the scanner 10 is returned to the home position (STP423), the paper of the printer is discharged, and the copy operation is finished (STP424).

If the number of lines is 7 instead of 21, (STP
418), STP for printing the middle nine of FIG.
The flow branches from 417 to STP 419, and “11” is set in the color counter 1. Then, the contents of the color counter 1 are copied to the color counter 2, the color counter 2 is set to "11", and the process returns to the printing operation (STP422).

The number of lines is not 21 but not 7 and 14
If so (STP420), the flow branches from STP418 to STP420 to print the lower nine of FIG. Then, the contents of the color counter 1 are copied to the color counter 2, the color counter 2 is set to "21", and the process returns to the printing operation (S
TP422).

FIG. 6 shows a plan view of a copy sample obtained by executing the flow shown in FIGS. 4 and 5. As shown in the figure, the color adjustment color is printed on the sheet 351 in 100 mm square, and the printing method is as described above.
First, 256 pixels from the top of adjustment color 1 are printed, and then 256 pixels from the top of adjustment color 2 are printed. And adjustment color 9
This is a method in which the paper is moved by one line after printing up to and printing is performed again from the adjusted color 1. After printing, the operator selects a desired color from the printed copy. Selected No. Enter the registered color No. selected by the numeric keypad. Are re-registered in (Fig. 13).

[0098]

According to the present invention, when the desired color to be registered does not exist on the original and can be obtained by adjusting the existing registered color, the registered color can be adjusted. A desired color can be made a registered color by adjusting.
