2. Description of the Related Art As shown in FIG. 1, as a print output of a document processor such as a word processor, there are four patterns depending on the direction of use of paper and vertical / horizontal writing. FIG. 2 shows a paper insertion direction for printing and a portion corresponding to the print buffer memory (print buffer).
That is, in the case of printing, after the dot information for printing is temporarily stored in the print buffer, the data in this print buffer is output to the printing unit to perform printing.

The arrangement of data in this print buffer is shown in FIG.
It shows in (A). Then, FIG. 3B illustrates this print buffer memory in an image manner. By the way, in this print buffer memory, in the case of FIG.

In the case of FIG. 1C, the character image in the direction as shown in FIG. 6 is stored. In the case of FIG. 1D, the character image in the direction as shown in FIG. 7 is stored. By the way, the character font corresponding to each character data is for vertical in the paper direction. The arrangement of the data of this character font is shown in FIG. Then, in FIG. 8B, this character font is represented as an image-like arrangement.

In this character font, one character is 2
It shows a case of being composed of 4 × 24 dots.
To store this character font as shown in FIG. 4, it is sufficient to write this character font data from the first byte of the print buffer. Further, the position where the writing of the next character is started is obtained by calculating the character pitch and the like from the size and direction of the paper at this time and the data such as vertical writing / horizontal writing.

To store this character font as shown in FIG. 6, it is sufficient to write this character font data from the L-th byte in FIG. The L-th byte for starting this writing can be obtained from the size of the paper and the data such as vertical writing / horizontal writing at this time. However, in the case of the horizontal direction in the paper direction, new character font data is additionally required as shown in FIGS. 9A and 9B as can be seen from FIGS.

Therefore, in the conventional printing apparatus, the character font data shown in FIG.
The character font data of (B) or FIG. 10 (C) is created and this character font data is written in a predetermined position of the print buffer. FIG. 11 is a block diagram showing the configuration of print control in the document processing apparatus according to the above method.

Reference numeral d) is a character font image generation unit for generating a font image corresponding to the printout of the document in the vertical writing / paper use direction and horizontal direction and outputting the writing position.

(5) is a font image writing unit. The font image writing unit (5) writes the font image generated by the character font image generation unit (4a to 4d) into the print buffer (6) according to the writing position from the character font image generation unit (4a to 4d). .. (7) is a printing device. This printing device (7) prints the contents of the print buffer (6).

FIG. 12 is a flow chart showing the flow of print control of this document processing apparatus. First, as shown in step 1, this document processing device reads the document data from the data storage unit (3). In step 2, the attribute of the document data is checked. In step 3, a corresponding character font image is generated according to the attribute. Then, in step 4, the data is written in the print buffer (6).

In step 5, it is checked whether all the print data for one line has been written. If not written, the process returns to step 1. If it has been written, the process proceeds to step 6 and printing is performed.

[0015]

As described above, according to the conventional art, when the paper direction is horizontal, the font must be processed for each character, which complicates the processing. It is an object of the present invention to provide a document processing device which simplifies the processing (rotation) of a font from one character font image generating means (4).

[0016]

A feature of the present invention is that a print image converting means for writing a character font image for at least one line into a print buffer (6) and rotating the print image developed in the print buffer ( 8)
Equipped with.

[0017]

According to the present invention, the print image converting means (8) for rotating the print image developed in the print buffer (6) rotates the image in the print buffer (6) at a time.

[0018]

EXAMPLES Examples of the present invention will be described below. FIG.
FIG. 1 is a block diagram showing the configuration of an embodiment of a document processing device of the present invention. The same parts as those in FIG. 11 are designated by the same reference numerals. (1) is an input unit for inputting characters, functions, etc., and inputs various document data.

(2) is a control unit composed of a microprocessor, and performs various data processing described later according to a control program. (3) is a document storage unit that stores the created document data. Reference numeral (4) is a character font image generation unit that generates a corresponding font image from the document data stored in the document storage unit (3).

(5) is a font image writing unit for writing the font image generated by the character font image generating unit in the print buffer (6).
(8) determines whether the document data is written vertically or horizontally, and whether the printing paper is used in the vertical direction or the horizontal direction, and if necessary, for one line written in the print buffer (6). A print image conversion unit for converting a font image.

(7) is a printing apparatus. The printing device (7) prints the converted print image by the print image conversion unit. The contents of the processing operation of this embodiment will be described with reference to the flowchart shown in FIG.
As shown in step 1 of FIG. 14, one character is 24 × 2.
In the case of being composed of 4 dots, in printing the document data as shown in FIG. 1A, when printing the document data for one line as shown in FIG.

That is, first, the character code is read from the document storage section (3). In step 2, the corresponding character font image is generated. In step 3, writing is performed in the print buffer (6) in consideration of the paper usage direction and vertical / horizontal writing. The image of the print buffer (6) at this time is of course the same as that shown in FIG. Next, in step 4, it is checked whether or not all the data for one print line has been written in the print buffer (6). If not, return to step 1. If the writing is completed, the document data and the paper use direction are determined in step 5.

In this case, since the document data is written horizontally and the paper is used in the vertical direction, it is not necessary to convert the image developed in the print buffer (6).
To print as is. By similar processing, FIG.
Even such document data can be printed.

When printing document data as shown in FIG. 1D, one line of document data as shown in FIG. 7 must be stored in the print buffer (6). In this example, 1
Data for one line is once written in the print buffer (6) with the image shown in FIG. Next, in step 5, the document data and the paper usage direction are determined.

In this case, since the document data is written vertically and the paper is used in the horizontal direction, the image developed in the print buffer (6) is processed by the print image conversion unit (8) in step 6 and then the print image conversion unit (8) shown in FIG. To convert. And
In step 7, printing is performed. In writing the character font shown in FIG. 15A, as shown in the figure, the third byte of the character font is written up to the third byte of the print buffer. Then, the 4th to 6th bytes of the character font are written to the Kth byte to (K + 3) th byte of the print buffer. In this way, the data will be written separately for each 3 bytes. This is the same when writing the next character font. First, the writing position in the print buffer (6) is calculated based on vertical writing / horizontal writing, paper usage direction, and the like. And, for example, the first byte of the character font is 3
Up to the 4th bit of the 4th byte of the print buffer is written up to the 4th bit of the 7th byte. And
Writing from the 4th byte to the 6th byte of the character font is performed from the 5th bit of the (K + 4) th byte to the 4th bit of the (K + 7) th byte of the print buffer. In this way, the data is written separately for each 3 bytes. The writing position is
Naturally, when the print image conversion unit (8) performs rotation processing,
It is calculated so as to obtain a desired image.

As described above, the character code is written into the print buffer (6) by one font image development process, and after writing, the entire print buffer is rearranged and rotated to convert and write the conventional character by character. Processing can be performed at higher speed than that. By the same process, the document data as shown in FIG. 1B can be printed. At this time, of course, the directions of rotation are opposite.

Further, in the present embodiment, character data has been described, but it is possible to print not only character data but also a document including graphic data and image data by performing the same processing. is there. Further, in this embodiment, one line is converted at a time, but this is
It may be two or three lines.

In this embodiment, only printing has been described, but the data written in the print buffer before conversion has the same display as the surface as shown in FIG. It is also possible to use it for writing to the memory.

[0029]

As described above, according to the present invention, since at least one line of characters is rotated in the print buffer, the process is faster than the conventional conversion and writing of each character. It can be carried out.
