2. Description of the Related Art Conventionally, in a facsimile apparatus having a monochrome and color copy function, it has not been possible to change the copy mode during copying. For this reason, characters and the like often arranged especially at the lower end of a postcard-printed recording paper such as a New Year's card (generally, characters such as greetings and addresses are arranged at the lower end of a postcard-printed recording paper such as a New Year's card) When printing black characters, the same processing as for the image portion was performed, so that black characters were forced to be printed by color synthesis, and the outline was compared to black ink printing. There is a problem that the part is easily blurred.

[0003]

However, when a bubble jet (registered trademark) printer is used as a printer, due to mechanical restrictions of the bubble jet printer,
The recording paper is skewed at a part of the rear end of the recording paper. On the other hand, the heads of the bubble jet printer are arranged in a straight line in the order of YMCK.
When printing is performed, the recording paper is fed to the position of the head of the next color every time one color is printed. Therefore, in order to print one line, a minimum of four feeds of the recording paper are required. Each time the recording paper is fed, the recording paper is skewed, so that the printing position is shifted and four types of deviations occur in the printed image. There was a problem that would occur.

[0004] Therefore, from the viewpoint of quality assurance, the lower end of the recording sheet where skew occurs must be controlled so as not to print during color copying.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. This is an example of a facsimile apparatus, and this facsimile apparatus has a CPU (central processing unit) 1 and a ROM.
(Read only memory) 2 and RAM 3 (random access
memory) and PC-I / F (personal computer interf)
ace) 4, image memory 5, and NCU (network control)
unit) 6, a scanner 7, a printer 8, and an operation unit 9
, A display unit 10, an image processing unit 11, and a modem 12 are mutually connected via a system bus.

The ROM 2 stores a control program. The CPU 1 controls each part of the facsimile apparatus according to a control program in the ROM 2. RAM3 is C
It is used as a work area for PU1. PC-I
/ F4 is for connecting to the host computer. The image memory 5 stores image data.
The NCU 6 connects to a telephone line. Scanner 7
Is for reading an original and converting it into an electric signal. The printer 8 records an image on a recording sheet. The operation unit 9 is for operating various keys. The display unit 10 displays the status of the facsimile machine to the operator. The image processing unit 11 converts RGB image data read by the scanner 7 into CMYK image data to be output to the printer 8. Modem 1
Numeral 2 is for data communication with the partner terminal through the NCU 6.

FIG. 2 is a flowchart showing an example of a control program stored in the ROM 2 of FIG. In the present embodiment, it is assumed that two parameters of the black printing start line value are set in advance by the operator if black printing is performed only in the rear end designated range.

When the start key of the operation unit 9 is pressed by the operator, it is determined whether or not a document is set on an ADF (auto document feeder) (S2). The operator waits until a document is set by the operator. On the other hand, if it is determined that a document is set, it is determined whether a communication destination is designated (S3). If it is determined that the communication destination has not been specified, communication processing is performed (S1).
0) If it is determined that the communication destination has been designated, it is determined whether the start key has been pressed (S4).

If it is determined that the start key has not been pressed, it is determined whether or not image quality has been selected (S
5). As the image quality selection by the operator, in the case of color copying, any of standard, fine, and postcard sizes is possible. If it is determined that the image quality has been selected, the setting value of the copy image quality parameter is changed to an operator-specified value (S11). On the other hand, if it is determined that the image quality selection has not been performed, the operator does not instruct the image quality selection and the image reduction selection, so the default value or the setting value used in the previous copy is used.

Next, it is determined whether or not an image reduction selection has been made by the operator (S6). There are three stages (90%, 80%) for the image reduction selection by the operator.
%, 70%). When it is determined that the image reduction selection has been performed, the setting value of the image reduction selection is changed to the operator-specified value (S12), and thereafter,
It returns to step S4. On the other hand, when it is determined that the image reduction selection has not been performed, the process returns to step S4.

In the loop of steps S4 to S6, the operator waits for the change of the copy image quality parameter and the image reduction selection by the operation unit 9, and when the start key is pressed, these settings are validated and the copy processing is started. Is done.

On the other hand, if it is determined in step S4 that the start key has been pressed, it is determined whether the copy image quality / parameter is postcard copy. In copying, normal copying and postcard copying have different controls in both the main scanning direction (horizontal direction) and the sub-scanning direction (vertical direction). Therefore, normal copying processing and postcard copying processing are separate processing.

If it is determined that the postcard size has been selected in the image quality selection range, postcard copy processing is performed (S8), and when this processing ends, end processing is performed (S8).
9). On the other hand, if it is determined that standard or fine has been selected, normal copy processing is performed (S13), and when this processing ends, end processing is performed (S9).

In the termination processing, the control parameters of each device are restored, the used hardware resources, the image memory,
Initialize the RAM area and others.

Next, the processing procedure of step S8 will be described in detail with reference to FIG. When the postcard copy process is started, it is determined whether or not the copy is a color copy to separate the processes of the color copy and the monochrome copy (S21). If it is determined that the copy is not the color copy, the monochrome copy process is performed (S34). On the other hand, if it is determined that color copying has been performed, processing of color copy parameters is performed (S22).
Here, the operation mode of the entire apparatus is set to color copy.

When the color copy parameter processing is completed, the reading mode is set to color for reading a color image by the scanner 7 (S23). When color reading is performed by the scanner 7, each line of the document is read while being divided into three primary colors of R, G and B.
Lighting and reading of the light source are repeated three times. Then, in order to read the next line, a process of driving the reading motor to move the original to the reading position of the next line is required.

Then, the recording image processing is set to color (S24), and the image read by the scanner 7 is read by the printer 8
Is changed to the device setting for converting into print data (CMYK format). Thereafter, one line is read (S2
5) Recording is performed (S26), and it is determined whether or not current line ≧ last line, that is, whether or not copying is completed (S2).
7) If the last line is determined, postcard copy end processing is performed (S35). Then, step S9 (FIG. 2)
To end processing.

On the other hand, if it is determined that the line is not the last line, it is in the middle of copying, and it is determined whether or not to perform rear end black printing (S28). If the setting by the operator is not the trailing end black printing, the process returns to step S25. On the other hand, if the setting by the operator is rear end black printing, it is determined whether the black printing start line value set by the operator is normal (S29).

If it is determined that the black print start line value is not normal, the process returns to step S25. On the other hand, when it is determined that the black print start line value is normal, it is determined whether or not the current line = black print start line, that is, whether or not the black print start line has been reached. If it has not reached the black print start line, the process returns to step S25.

On the other hand, if it is determined that the black print start line has been reached, the parameters are changed after the black print start line in order to copy with black ink (S3).
1). The operation mode of the entire apparatus is set to monochrome copying, and the reading mode is set to black mode for reading a monochrome image by the scanner 7 (S32). When scanning in black and white with a scanner, unlike in color scanning, only black is read on each line of the document.
Lighting and reading of the light source need only be performed once per line. Then, in order to read the next line, a process of driving the reading motor to move the original to the reading position of the next line is required. If the recording image processing is set to the black mode (S33), the printing control of the printer is changed to black printing, and a printing operation is performed, a monochrome copy can be operated. When this process ends, the process returns to the step S25. Thereafter, the copy process is performed in a loop of steps S25 to S30 until the copy is completed, and if current line ≧ final line is satisfied (S27),
Postcard copy end processing is performed (S35).

[0029]

As described above, according to the present invention,
With the configuration described above, reading, image processing, and recording processing performed in color can be printed using only monochrome ink from a position where an image during color copying is disturbed. Therefore, at the time of color copying, not only "color bleeding", which has occurred due to a conveyance failure of the printer, can be avoided, but also a clearer print can be performed than character printing by conventional color synthesis.
