Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing device,
In particular, the present invention relates to a document processing device that can initialize designated format information by a simple operation.

[0002]

2. Description of the Related Art Conventionally, in a general document processing apparatus,
When displaying the input data, the format information that indicates the character size and decoration status of the input data is indicated by a mode mark, and the character data that is the target of the format information is displayed after the mode mark. To be done. When the format information is specified by specifying the range or the cursor is moved to the position where the format information is located and the format information is deleted, the data after the deleted format information is based on the previous format information. But when the format information is at the beginning of the text,
Since there is no format information before that position, the format information at the beginning of the text could not be deleted. Further, the operation of deleting the format information at the head has been notified to the user as an error.

When the format information at the head is to be returned to the initial value, the memory storing the format information is reset or the format information such as the size and the modified state is returned to the initial value one by one. It is carried out.

[0004]

However, since the format information and the input character data are stored in the same memory, if the memory is reset in order to restore the format information at the beginning to the initial value, Although the format information in can be easily returned to the initial value, there is a problem that the input data is also deleted, and if the format information is returned to the initial value one by one, the format information is returned to the initial value. However, there is a problem that the operation is very troublesome and the operability is poor.

The present invention has been made to solve the above-mentioned problems, and when the format information at the head is returned to the initial value, it can be easily initialized with the character data remaining. To provide.

[0006]

To achieve this object, a document processing apparatus according to the present invention comprises an input means for inputting characters such as characters and symbols and various commands, a display, and input characters. And a data storage unit for storing format information data based on various commands, including a deletion designation unit for designating deletion of the data stored by the data storage unit and a deletion designation unit. First to judge whether the created data is format information
Judging means, and second judging means for judging whether or not the data of the format information judged by the first judging means is located at the head of the data stored by the data storing means.
When it is judged by the second judging means that it is not at the beginning,
It is provided with a deleting means for deleting the data of the format information and an initial value changing means for changing the format information to an initial value when the second judging means judges that the data is located at the head.

Further, it is conceivable that the deleting means deletes the data which is judged not to be the format information by the first judging means.

Further, the document processing apparatus may include initial value storage means for storing the initial value.

[0009]

According to the document processing apparatus of the first aspect of the present invention having the above structure, the data designated by the deletion designating means among the data stored in the data storage means is designated by the first determining means. When it is determined that the data is format information and the data is located at the head of the data storage means by the second determining means, the initial value changing means changes the format information to the initial value.

On the other hand, the data designated by the deletion designating means is judged by the first judging means to be format information,
When the second judging means judges that the data is not located at the head of the data storing means, the deleting means deletes the data.

Further, the document processing apparatus according to claim 2 has the same operation as that according to claim 1, but the data designated by the deletion designating means is judged not to be the format information by the first judging means. Then, the deleting means deletes the data.

An initial value is stored at the head of the parameter table for each type of format information.

The line buffer 41 of the RAM 40 temporarily stores document data composed of a plurality of characters and symbols input from the keyboard 3 and code data of format information. A deletion start position is stored in the deletion start pointer (this content is the text pointer value SSP) 42. A deletion end position (this content is a text pointer value SEP) 43 stores the deletion end position.

Next, the tape print control routine executed by the controller C of the tape printer 1 will be described with reference to the flow charts of FIGS. Incidentally, reference numeral S in the figure
i (i = 10, 11, 12, ...) Is each step.

When the power is turned on by operating the power key, this control is started, and initialization such as clearing each of the memories 41 to 47 is first executed (S10), and the code stored in the line buffer 41 by the initialization. The characters, symbols, and format information corresponding to the data are displayed on the display 22 (S
11). Immediately after the power is turned on, only the mode mark “▲” is displayed. The format information at this time stores the initial value of each information. When the character input key is operated (S13: Yes), the data of the input document is stored in the line buffer 41 and the process returns to S11. For example, when “ABCD” is input as the document data, “▲
"ABCD" is displayed on the display 22.

Next, when the format key for changing the format information is operated (S14: Yes), the format information changing process is performed (S20). The format information change process is shown in FIG.
First, a format information selection screen is displayed as shown in (S4).
0). When the font size is selected on the selection screen (S
41: Yes), one of the character size parameters shown in FIG. 4 is selected and its value is changed as the character size information of the format information (S46). When the character modification is selected (S42: Yes), one of the modification parameters shown in FIG. 4 is selected and its value is changed as the character modification information of the format information (S47). When half-width / double-width is selected (S43: Yes), one of the half-width / double-width parameters shown in FIG. 4 is selected and the value is changed as half-width / double-width information of the format information (S48). When the italic type is selected (S44: Yes), one of the italic parameters shown in FIG. 4 is selected and the value is changed as the italic type information of the format information (S49). When the end is selected, the changed format information is stored in the line buffer 41 and the mark is displayed on the display. (S50).

Next, when the range designation key is operated (S15: Yes), the range designation key is processed (S2).
1). In the range designation key processing, the current cursor position is stored in the deletion start pointer 42 and the deletion end pointer 43 as shown in FIG. 8, and the current cursor position (character “A” is displayed as shown in FIG. 9A). Is displayed in a reversed state (S60).

When the cursor right move key is operated (S62: Yes), the deletion end pointer is incremented by 1 (S65). For example, when the cursor right movement key is operated in the state shown in FIG. 9A, as shown in FIG. 9B,
The character "B" is displayed upside down. When the cursor left movement key is operated (S63: Yes), the deletion start pointer is decremented by 1 (S66). For example, in FIG.
When the cursor left movement key is operated in the state shown in (a), the mode mark "▲" is inverted and displayed as shown in Fig. 9C. When the return key is operated (S64: Yes), the range designation operation ends.

Next, when the delete key is operated (S
16: Yes), the delete key is processed (S22). As shown in FIG. 6, the process of the delete key is performed first by the line buffer 4
In 1, it is judged whether the data at the position stored in the deletion start pointer 42 is the format information code (S30), and if it is not the format information code (S30: No), the data deletion processing for deleting this data from the line buffer 41 is executed. Execute (S33).

On the other hand, if it is a format information code (S30: Y
es), it is determined whether the value stored in the deletion start pointer 42 is the head of the input text data (S).
31). If it is not the beginning of the text data (S31:
No), the data deletion process is executed (S33), and if it is the head of the text data (S31: Yes), the initialization process for changing the format information to the initial value is executed (S32).
Here, the initial value indicates the beginning value of various parameters shown in FIG. 4, the character size is AUTO, no decoration, full-width,
It is the content that there is no italics.

When the initialization of the format information or the data deletion processing is completed, it is judged whether the value of the deletion start pointer 42 is the same as the value of the deletion end pointer 43 (S34). If not (S34: No), the deletion start pointer 42 Increase the value by 1 (S35) and return to S30. If the value of the deletion start pointer 42 and the value of the deletion end pointer 43 are the same (S34: Ye
s), the deletion process ends.

For example, as shown in FIG.
BC [▲ DE] F ”(“ ▲ DE ”is highlighted.
Here, [] is shown in between. The same applies hereinafter. ) Is entered and the range is specified from the position of the mode mark “▲” in front of the character “D” to the character “E”, the delete key is operated before the character “D”. Since the mode mark "▲" is not at the beginning of the text, all the data specified in the range is deleted and displayed as "▲ ABCF" as shown in FIG. 10B.

Further, as shown in FIG. 11A, "[▲ A
B] C ▲ DEF ”is entered, and the character“ B ”starts from the position of the mode mark“ ▲ ”in front of the character“ A ”.
When the delete key is operated with the range specified up to, the mode mark "▲" in front of the character "A" is the beginning of the text, so as shown in Fig. 11B, "▲ C ▲ D
"E" is displayed and the mode mark "▲" in front of the letter "C"
The format information of is changed to the initial value.

Next, when the print key is operated (S
17), the font of the data stored in the line buffer 41 is expanded based on the format information, and the printing process is executed (S23). When the other keys are operated, each key is processed (S18).
