Description

The present invention relates to a character processing device such as a word processor.

(B) Conventional technology Recently, word processors have become extremely popular, and various document creation functions can be used to easily create printed documents by converting the document data input from the keyboard into kanji mixed sentences and then printing. It is possible. By the way, one of the document creation functions is a function for displaying and printing characters in half-width characters, and it is configured such that horizontal printing or vertical writing can be selected at the time of printing. As shown in Fig. 7, when the characters displayed horizontally are printed vertically, half-width characters are not printed vertically as shown in Fig. 8, or with the Sanyo word processor SWP-3400. As shown in the operation manual, there is one in which two half-width characters are printed vertically as shown in FIG. 9, but all of them are unnatural and improvements have been demanded.

(C) Problems to be Solved by the Invention It is an object of the present invention to provide a character processing device for vertically printing half-width characters with a simple structure without unnatural writing.

(D) Means for Solving Problems The character processing device of the present invention is a half-width character, a full-width character, and horizontal writing / writing.
Input means (4) such as a keyboard for inputting data in the vertical writing format, a character generator (8) for generating a full-width character pattern corresponding to the character data, and horizontal / vertical writing printing are selected. When performing vertical writing of full-width characters with the print control circuit (11), the full-width character pattern is transferred to the print control circuit (11), and when performing vertical writing of half-width characters, the vertical direction of full-width character patterns And a main control unit (1) for transferring the data to the print control circuit (11) after being compressed to 1/2.

(E) Operation In the present invention, when vertical writing is designated, if there is a half-width character, the full-width character pattern is converted into a half-width character for vertical writing and printing is performed.

(F) Embodiment One embodiment of the present invention will be described below with reference to the drawings by taking a word processor as an example.

(1) is connected to each device described later by a signal bus (2),
A main control unit that controls the whole by sending and receiving signals, is composed of a microprocessor, and according to the program of the program memory (3) in which the processing program is stored in advance, the calculation and comparison of the data for document creation, etc. The processing operation of is performed. (4) is a keyboard composed of an alpha bed, a kana, a numeric keypad, etc. for inputting document data or designating a printing format. (5) is an input buffer circuit that temporarily stores the data input from the keyboard (4).
The input data is transmitted via the signal bus (2). Reference numeral (6) is a memory for storing document data that has been created or is being created by processing such as Kanji conversion performed by the main control unit (1), and writing and writing of data by the main control unit (1). The reading is controlled and each character is coded and stored, for example, using 4 bytes of a character code 2 bytes and an attribute code 2 bytes. (7) is a dictionary memory used when converting the characters entered in Kana to Kanji,
Kanji is coded and stored, and is used for Kanji conversion when read by the main controller (1). (8) is a character generator that generates a character pattern, and generates a character pattern of the corresponding character by dot information by addressing by the main controller (1). It is assumed that each character is now composed of a matrix pattern of 16 × 16 dots.
The character generator (8) also stores a character pattern of half-width characters, which is composed of a matrix pattern of 16 × 8 dots. Reference numeral (9) is a display control circuit for controlling the display device (10) so that the character data input from the keyboard (4) or the data converted into the Chinese character, the cursor, etc. are displayed on the display device (10). Under the control of (1), horizontal writing is displayed on the display (10) based on the character pattern supplied from the character generator (8). The display (10) is composed of a CRT or a liquid crystal display, and in the case of a document larger than the size of the display (10), the document data is scrolled vertically and horizontally. (11) is the transfer of character data to be printed, and is a printing control circuit that controls the printing device (12) to perform printing, and performs horizontal writing or vertical writing based on the supplied character pattern of the printing character. Controls print data supplied to the printer (12). The printing device (12) is composed of a dot printer such as wire dot, thermal transfer, thermal, etc. In the present case, it is assumed that printing is performed by a 16-dot vertical 1-line print head according to the character pattern of the character generator (8). To do. It should be noted that the distinction between horizontal writing and vertical writing is made in the character pattern data of the 16 × 16 dot matrix of the characters to be printed shown in FIG. When 16 dots of data are read and supplied to the print head in the row and column direction, horizontal writing is performed. On the other hand, 16 dots of data are read and supplied to the print head in the 1 ', 2', 3'rows. In the case of vertical writing, the main controller (1)
Is controlled by the print control circuit (11).

Next, the operation of the present invention having such a configuration will be described.

First, when a character is entered with a kana from the keyboard (4),
Based on the entered character code, the main controller (1)
The character generator (8) generates a corresponding character pattern and supplies it to the display control circuit (9) to display the input character on the display (10). When it is not necessary to convert the input character, it is displayed as it is and stored in the memory (6) as a character code. On the other hand, when converting the input kana character into kanji, when the kanji conversion key is operated on the keyboard (4), the main control unit (1) which has received the kanji conversion key signal is stored in the program memory (3) in advance. The corresponding kanji is searched from the dictionary memory (7) according to the existing kanji conversion program, and if the corresponding kanji is found, the character generator (8) is driven to display it on the display (10) and the kanji is stored in the memory (6). Remember the code of. If you enter half-width characters,
When a character is entered after the half-width mode is set with the mode key of the keyboard (4), the entered character is attached with an attribute code indicating the half-width and is stored in the memory (6) together with the character code. A half-width character pattern is read from the generator (8) and displayed on the display (10). In this way, the character data input from the keyboard (4) is displayed on the display (10) while being appropriately converted to Kanji and stored in the memory (6) to create a document.

Next, the operation of printing the created document will be described. For example, the operation of printing the input characters as shown in FIG. 7 will be described. When printing, the printing mode is set in advance and then printing is started. In this case, the distinction between horizontal writing and vertical writing will be described.

First, when horizontal writing is designated, the main control unit (1) sequentially reads the character data stored in the memory (6) by a print start operation, and based on the character code stored in the memory (6), a character generator ( A character pattern is generated from 8) and is supplied to the buffer of the print control circuit (11). The buffer has a capacity capable of storing a character pattern for one line, and when the printing of the contents of the buffer is completed, the next print data is sequentially input to the buffer. Since printing is currently specified for horizontal writing, the print control circuit (11) reads out 16-dot data in the column direction of the character pattern and supplies it to the print head of the printing device (12) to perform horizontal writing. At this time, for half-width characters, 16-dot data in the column direction is read out, so that half-width characters are printed in the same manner as in FIG.

Next, regarding the operation to print the same character data vertically,
A description will be given based on the flowchart of FIG. First, when vertical writing is designated by the print format setting and printing is started, main controller (1) determines whether the character code of the character read from memory (6) is a half-width character. When the character code is not half-width, main controller (1) reads the character pattern corresponding to the character code from character generator (8) and transfers it to the buffer of print control circuit (11). However, when the character code of the read character is a half-width character, the half-width character pattern read from the character generator (8) is once stored in the memory (6), the character pattern is converted as described later, and then the print control circuit (1
Transfer to the buffer in 1). When the print data for one line is transferred to the buffer of the print control circuit (11) in this way, the print control circuit (11) controls the printing device (12) to perform vertical writing printing.

Next, the operation of changing the above-mentioned half-width character pattern into a character pattern for vertical writing will be described. Now Fig. 3 (a)
A case where the horizontal writing character pattern of the number "1" generated from the character generator (8) shown in FIG. 3 is converted into the vertical writing character pattern shown in FIG. 3B will be described. As can be seen from the converted character pattern, in the present embodiment, the logical sum of 2 dots in the vertical direction of the character pattern of FIG. 3 (a) is obtained, and is vertically set as 1 dot in the vertical direction of FIG. 3 (b). In this configuration, the horizontal compression of the character pattern of FIG. 3 (a) is expanded to one horizontal dot of FIG. 3 (b). The operation in which the main controller (1) calculates and obtains these relationships is shown in the character pattern configuration of FIG. 4 and the flowchart of FIG.
Convert a horizontal writing half-width character pattern (13) to a character pattern (14) that is compressed only in the vertical direction, and then convert it to a character pattern (15) that expands the horizontal direction to a full-width. Converting. As for the relationship between these character patterns, the dots bi, j in the character pattern (14) are bi, j = A2i−1, j + A2i, , And the dots of the character pattern (15) are Ci, 2j-1.
＝ bi, j Ci, 2j ＝ bi, It is shown by two equations. Therefore, when the half-width character code is detected, the main controller (1) performs the arithmetic processing according to the flowchart shown in FIG. The conversion process is sequentially performed from the first column in this order. That is, the character pattern (13) is a character pattern (1
4) is converted to. Subsequently, the main controller (1) changes the character pattern (14) to the character pattern (15) by using Ci, 2j
-1 = bi, j and ci, 2j = bi, j are calculated and converted into a character pattern (15). In this way, the half-width character pattern of the numeral "1" is converted into the character pattern shown in FIG. 3 and then transferred to the buffer of the print control circuit (11). When the print character pattern data for one line is transferred to the buffer of the print control circuit (11), since the print control circuit (11) designates the vertical writing printing, it is stored in the buffer as shown in FIG. The data is read line by line in the order of 1 ', 2', 3'lines from such a character pattern, and is sequentially supplied to the print head consisting of 16 dots arranged in one vertical column to rotate the character pattern 90 degrees. The shape is printed, that is, vertically written.
Therefore, in the present case, one character is composed of 16 dots, so in the case of a double-byte character, one character is printed in 16 times, and in a half-width character, it is printed in 8 times. Thus, horizontal half-width characters as shown in FIG. 7 are also printed vertically as shown in FIG.

The above description of the embodiment has been given to the case where the character generator has a half-width character pattern. However, alphanumeric characters such as "1, 2, 3 ..., a, B, C ..." are generally provided with a half-width character pattern in the character generator, but the kanji is provided with only full-width characters and not a half-width pattern. .

This kanji will be explained.

In other words, when displaying half-width characters such as Chinese characters stored in full-width character patterns in the character generator and printing them vertically, the full-width character patterns are compressed to 1/2 in the horizontal direction by the same method as above. By converting to a half-width character pattern for horizontal writing and displaying, and by converting from a full-width character pattern to a half-width character pattern for vertical writing in which the vertical direction is compressed to 1/2, full-width characters such as kanji are also half-width. It is possible to print vertically.

In the present embodiment, the case where the character pattern is 16 dots has been described, but the same can be applied to the case where the character pattern is 24 dots or 32 dots.

Furthermore, although the embodiment has been described with respect to the word processor, the present invention is not limited to this and can be applied to an electronic device that performs similar character processing.

(G) Effect of the Invention As described above, in the character processing device of the present invention, when half-width characters are included in a document when a document is printed vertically, a full-width character pattern is used for vertical writing. Since it is converted to a character pattern of / 2, half-width characters can be printed vertically without unnaturalness even if there is no character generator that outputs half-width character patterns for vertical writing.
