Description

Description: TECHNICAL FIELD The present invention relates to a document data processing device that performs character printing and image printing.

2. Description of the Related Art Conventionally, in a word processor or the like provided with a printing device, various print modes are prepared in advance according to print density, print speed, and the like. Is selectively set, data printing is performed in the set print mode.

[Problems to be Solved by the Invention] By the way, document data (characters such as characters) is in a print density “normal” mode and print speed “normal” mode, and image data is in print density “agriculture” mode and print speed. Printing in the "slow" mode is more optimal for both the beauty of the printed matter and the speed of printing.

However, conventionally, since data printing is performed in a print mode established in advance, when document data and image data are mixed, if a print density “normal” mode and a print speed “normal” mode are set, The printing speed is faster, but the image data cannot be printed with high quality. If the print density "Agriculture" mode and the printing speed "Slow" mode are set, the image data can be printed with high quality. However, there was a disadvantage that the printing speed was slow.

It is an object of the present invention to enable a stored document to be printed in an optimal printing state.

[Means for Solving the Problems] The means of the present invention are as follows.

A document storage unit for storing a document in which document data composed of character codes and image data composed of image images are mixed; a printing unit for printing in a plurality of print modes; and sequentially reading data from the document stored in the document storage unit Discriminating means for discriminating between document data and image data according to whether the read data is a character code or an image image; and when the discriminating means discriminates the document data, the character code Is converted to a dot pattern and printed according to the print mode set in advance for character printing, and if it is determined that the image is an image pattern, the image is printed according to the print mode set in advance for image printing. Print control means for controlling the printing means so as to perform printing.

Therefore, a document in which document data and image data are mixed is stored, and data is read from the stored document in predetermined units. When the read data is determined to be document data, a character Converts the code into a dot pattern and prints it according to the print mode set in advance for character printing, and when it is determined that the image is image data, converts the image according to the print mode set in advance for image printing. Printing.

[Explanation of Functional Block Diagram] FIG. 1 is a functional block diagram of the present invention.

Now, it is assumed that data in which image data is mixed in the document data is to be printed and is printed.

First, in FIG. 1, reference numeral 1 denotes a discriminating unit which discriminates the type of data to be printed when a print command is given from a keyboard or the like.

Here, if the data to be printed is document data,
The mode setting means 3 sets, for example, a print density "normal" mode and a print speed "normal" mode as print modes. Then, the printing unit 4 prints the document data in the print data storage unit 1 in the print mode set by the mode setting unit 3.

On the other hand, if the data to be printed is image data, the mode setting means 3 sets, for example, a print density “far” mode and a print speed “slow” mode as print modes. Then, the printing unit 4 prints the image data in the print data storage unit 1 in the print mode set by the mode setting unit 3.

Embodiment An embodiment will be described below with reference to FIGS. 2 to 4.

 FIG. 2 shows the basic configuration of the word processor.

The CPU 11 controls the operation of the word processor according to various programs stored in the ROM 12, and a key input unit 13, an image scanner 14, a CRT display unit 15, and a printer 16 as corresponding peripheral devices control input control. It is connected to the CPU 11 via a unit 17, an image control unit 18, a display control unit 19, and a print control unit 20.

The key input unit 13 has a data input key AK for inputting document data and image data on the keyboard, a print key BK for starting data printing, and the like.The input control unit 17 has a key code corresponding to the operation key. The key code read from the input control unit 17 by the access from the CPU 11 is stored in the text memory 21 or the CRT display unit 15
Is output from the text screen.

The image data read by the image scanner 14 is taken into the CPU 11 via the image control unit 18 and stored in the text memory 21 or the CRT display unit 15.
Display output from

When a print command is given from the key input unit 13, the CPU 11
The data in the text memory 21 is read out for each predetermined unit, converted into a dot pattern, and written into the print buffer 22.At this time, it is determined whether the data read out from the text memory 21 is document data or image data, and The print mode corresponding to the determination result is set. Here, the print control unit 20 sequentially reads out the data in the print buffer 22 and causes the printer 16 to print out the data. At this time, the print control unit 20 controls the print density and print speed according to the set print mode.

 Next, the operation of this embodiment will be described.

FIG. 3 is a flowchart which is started when a print command is given from the key input unit 13.

Now, as shown in FIG. 4 (A), an example is shown in which, on one page, data including document data in the upper part, image data in the middle part, and data including document data in the lower part are designated as print targets. This will be described in detail below.

First, the pointer value of the text memory 21 is reset (step S1). Then, it is checked whether or not data is stored in the text memory 21 at the address position (pointer position) determined by the pointer value (step S2). Here, assuming that the pointer position is the hatched portion in FIG. 4A, the presence of data is detected in step S2, and the process proceeds to step S3, where the type of the read data is determined. Now that the document data is read, the document data is transferred to the print buffer 22 (step S
4) In this case, since the print buffer 22 has not reached the full state, the fact is detected in step S5, and the process proceeds to step S8 to check whether the data at the pointer position is document data. In this case, since the data is of course document data, the process proceeds to step S9, and after updating the pointer value, returns to step S2. Therefore, if the data read from the text memory 21 is document data, the document data is transferred to the print buffer 22 character by character while updating the pointer value until the print buffer 22 becomes full.

Here, when the print buffer 22 becomes full and the document data of a predetermined unit (for example, one line) is transferred into the print buffer 22, the process proceeds to step S6, where the print density “normal” mode and the print speed “normal” are set. ”Mode. Then, the document data in the print buffer 22 is printed out from the printer 16 based on the setting mode (step S7).

Then, the process proceeds to step S8. In this case, since the document data is also document data, the point value is updated (step S9). Print line by line. As a result, the document data in the upper part of FIG. 4A is sequentially printed out, for example, line by line.

Since the image data is stored in the middle part of FIG. 4A, the text memory is stored in step S3.
If it is detected that the data read from the document memory 21 is not document data, that is, if the image data is read from the text memory 21, the process proceeds to step S10, and it is determined whether or not there is data in the print buffer 22. In this case, the print buffer 22 is
Since there is no document data already in, step S1
Proceeding to 1, the image data read from the text memory 21 is transferred to the print buffer 22. Then, until the print buffer 22 becomes full (step S12).
The pointer value is updated (step S16), and the process returns to step 11 on the condition that the data at the pointer position is image data (step S17), and transfers this image data to the print buffer 22.

Here, when the print buffer 22 is full, the process proceeds to step S13, where the print density “far” mode and the print speed “slow” mode are set, and the image data in the print buffer 22 is printed in this setting mode (step S13). S1
Four). Similarly, when the image data is read from the text memory 21, the image data is transferred into the print buffer 22 while updating the pointer value until the print buffer 22 is full, and when the print buffer 22 is full, the print buffer is The image data in 22 is printed according to the setting mode. As a result, the image data shown in FIG. 4A is printed with higher quality than the document data.

When printing of all the image data shown in FIG. 4A is completed, the pointer value is updated again (step S16). In this case, the data at the pointer position is not image data but document data. There are steps
In S17, this is detected, and the flow advances to step S18 to check whether or not data exists in the print buffer 22. Since no data remains in the print buffer 22 immediately after the printing of the image data, the process returns to step S2. As a result, as described above, if the data to be printed next is document data, document printing processing (steps S4 to S9) is performed. Therefore, when the printing of the image data is completed, the fourth
The process proceeds to the process of printing the document data shown in the lower part of FIG. 7A. When the printing of the document data is completed, the absence of data is detected in step S2, and the printing process is completed.

In the example of FIG. 4A described above, even if document data and image data are mixed on one page, they are divided into blocks at the upper, middle, and lower stages. FIG. 4B shows an example in which image data is present in the document data in the upper part.

In this case, while updating the pointer in step S9, the document data in the upper part is printed one character at a time in the print buffer.
22 (step S4), but when the pointer position comes to the hatched portion in FIG. 4B, the data at that pointer position is image data, so that it is detected in step S3 and step S10 is performed. Proceed to. In this case, since the data at the pointer position was changed from document data to image data before the print buffer 22 became full, unprinted document data remains in the print buffer 22.
Therefore, in this case, the process proceeds to step S6, where the print density "normal" mode and the print speed "normal" mode are set, and the document data in the print buffer 22 is printed in this setting mode (step S7).

After printing the document data in this way, step
Proceed to S8, but in this case, since the data at the pointer position is image data,
Return to S2. Then, the process proceeds to step S10. In this case,
Since no data is detected, the flow advances to step S11 to transfer the image data at the pointer position to the print buffer 22. Then, the process proceeds to step S12, but since the print buffer 22 is not full, the condition that the data at the pointer position is image data is set (step S1).
5) The pointer is updated (step S16). Then, if the updated data at the new pointer position is also image data, the process returns to step S11 and transfers the image data to the print buffer 22. Hereinafter, the image data is sequentially transferred to the print buffer 22 while updating the pointer. If the data at the pointer position is document data when the pointer is updated (step
S17), it is checked whether or not data exists in the print buffer 22 (step S18).

In this case, since the data at the pointer position was changed from image data to document data before the print buffer 22 became full, unprinted image data remains in the print buffer 22. Therefore, in this case, the process proceeds to step S13, in which the print density is set to the "far" mode and the print speed is set to the "slow" mode, and the image data in the print buffer 22 is printed in this setting mode (step S1).
Four). Then, the process proceeds to step S15. In this case, since the data at the pointer position is the document data, the process returns to step S2, and then proceeds to the document data printing process.

As described above, when document data and image data are mixed in one line, printing is performed twice by dividing the document data into image data.

Note that the print mode is changed according to the document data and the image data. For example, by determining the data density of each data to be printed,
The print mode may be changed between the image data. Of course, the print mode is not limited to the print density and the print speed.

According to the present invention, when reading and printing a document in which document data and image data are mixed in the same document,
Since printing can be performed in an optimum print mode according to the type of read data, high-quality printing can be performed.
