Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a document creation apparatus having a line modification function.

[Technical Background of the Invention and its Problems] Conventionally, a document creating apparatus such as a Japanese word processor uses a CRT display as a document display mechanism and uses an external storage such as a floppy disk device as a document file mechanism. The configuration was large and expensive in terms of price. However, in recent years, various innovations and improvements have been made, such as using an LCD (liquid crystal display) as a display mechanism and a CMT (cassette type magnetic tape device) as a document file mechanism, thereby realizing a small, lightweight and low-priced device. Came to

In such a low-priced and compact document creation apparatus, for example, the display screen size of the LCD as an input mechanism is greatly restricted, and the screen size is as small as 1-2 lines and 10 characters. Things are used.

In such a low-priced and compact document creating apparatus that is restricted by the input mechanism and the output mechanism, it is possible to effectively use the input / output mechanism and to make it highly functional and multi-functional and easy to use. How to realize the device is a big issue.

For example, a conventional low-priced, compact document creation apparatus having a small number of display character digits does not have a function of temporarily stopping printing at an arbitrary line during printing.

Therefore, conventionally, for example, when the operator wants to change the printing form during printing, or when he wants to change the print ribbon color from a certain line position during printing to perform color-coded printing, or prints from a certain line position during printing. If you want to shift the position, and further, because the number of characters that can be displayed at one time is greatly limited, if you want to print out a part of the document and check or refer to it, you can easily implement these with simple operations. I couldn't.

[Object of the Invention] The present invention has been made in view of the above circumstances, and in a low-cost and compact document creation device with a small number of display character digits, a complicated operation is not required and a document is printed during printing. Printing can be temporarily stopped at any line of the line, enabling the operator to intervene in the printing operation at any line position during printing, and for example, the part of the line designation document area that cannot be displayed at once on the display unit. An object of the present invention is to provide a document creating apparatus that can easily realize various document printing such as printing, color printing, multi-column printing, etc.

[Summary of the Invention] According to the present invention, line attribute setting means for displaying a selection screen of attribute information including print stop instruction information in units of a line of document information and optionally setting the attribute information by an input means. A line attribute storage unit that stores the attribute information set by the line attribute setting unit in association with a line of the document information; and the attribute stored in the line attribute storage unit according to a print instruction of the document information. A print stop line search means for searching the print stop instruction information contained in the information; and a print stop control means for controlling the print operation to stop at the line position searched by the print stop line search means at the time of printing, It is configured to selectively print an arbitrary area of the output target document up to a specified line position. This makes it possible to temporarily stop printing at an arbitrary line in the middle of printing without complicated operations. It is possible to allow the operator to intervene in the printing operation at any line position during printing, for example, partial printing of the line designation document area that cannot be displayed at once on the display unit, color printing, multi-column printing, etc. Various document printings that are rich in changes can be easily realized.

Under the control of the cassette interface circuit 16 in the SI10, at the time of writing data, prior to the start of writing, All "1" data is written for about 10 seconds as a reader unit, and then bit serial cassette write data (line modification information / document information / external character pattern / registered word / temporary dictionary, etc.) output from PPI12 is written. Crowded,
After that, all "0" data is written as a trailer for about 2 seconds.

Here, the operation of the embodiment will be described with reference to the drawings.

When inputting a sentence containing Chinese characters, a key input signal input from the keyboard 30 is converted into Kana characters by the control of the CPU 11 in SI10 and stored in the document buffer 141 in the RAM 14. At this time, the CPU 11 outputs a scan signal to the keyboard 30 via the PPI 12 and further via the decoder 13, and inputs the return signal from the PPI 12 to determine the key and generate a key code. In addition, the ROM15 is used to specify the kanji that is entered in a kana based on the same key code.
After the kana-kanji conversion processing is performed by pulling the dictionary in the RAM 14 and further the temporary dictionary in the RAM 14, an input character code string including the converted kanji code is stored in the document buffer 141.

At the time of inputting the above-mentioned document, the input characters stored in the document buffer 141 are sequentially pattern-developed on the line image buffer 140 under the control of the CPU 11, and the LCD control circuit 1
The display control of 7 and the display drive of the LCD driver 51 display and output the maximum of 9 digits on the LCD 50.

The input document thus input can be arbitrarily displayed on the LCD 50 with a character string of up to 9 characters by operating the cursor keys, and is used for proofreading and correction of the document.

When you want to character-modify or to specify printing stop for each line in the above input document, select the character string at the line position you want to modify with the cursor key operation and display it. [Line modifier] by combining with the specific key of
Specify the line decoration by key operation.

When the CPU 11 determines the operation input of the [line modification] key,
The display mode of the LCD 50 is switched from the document display mode to the line decoration display mode. This is shown in FIG. FIG. 4 (a) shows the display state in the document display mode, and FIG. 4 (b) shows the initial display state switched to the line decoration display mode by the operation of the [line decoration] key. . Here, first, a selection screen for selecting the character spacing is displayed.

In this line modification display mode, selection screens are switched by operating the cursor keys in the vertical direction, and items are selected by operating the cursor keys in the horizontal direction.
For example, when the selection screen for selecting the inter-character spacing is displayed and the selection screen is switched by operating the cursor keys in the up and down directions without selecting items by operating the cursor keys in the left and right directions, the selection screen is changed. Assuming that the character spacing indicated by the cursor is selected, the item of the newly displayed selection screen is selected.

Display the "Print stop" selection screen by switching the above selection screen, move the cursor with the cursor key operation to select "Print stop", and then operate the [Select / execute] key The line decoration information having the control information “with stop” is stored in the line attribute storage area in the line attribute buffer 142 corresponding to the selected line position. FIG. 3 shows the correspondence between the line attribute buffer 142 and the document buffer 141 and the setting contents of the line decoration information at this time.

After the line decoration setting means has set the line decoration for an arbitrary line position of the document stored in the document buffer 141, the already input document in the document buffer 141 is displayed on the LCD 50 by operating the cursor keys. By displaying the same L
In the guide display section on the CD 50, the number of characters per line of the display character string and the number of characters per line are displayed, and a line decoration indicator and a battery consumption indicator are selectively displayed. The guide display form at this time is shown in FIG. 5, and the lighting control processing procedure of the line decoration indicator is shown in FIG.

That is, in FIG. 6, when a display character string is selected by operating the cursor, the line position, the column position, and the number of characters per line of the display character string designated by the cursor are displayed, and the line attribute buffer 142 is displayed. The line decoration information of the corresponding line position stored in is referred to, and this information is compared with the line decoration standard value to determine whether the line decoration is set for the display line selected by the cursor. (Steps A11 to A15 in FIG. 6).

Here, if the line decoration is not set, that is, if the content of the line decoration information matches the line decoration standard value, the line decoration indicator is not turned on, and if the line decoration is set, that is, If the content of the line decoration information does not match the line decoration standard value, the line decoration indicator is turned on (steps A16 and A17 in FIG. 6). Such display control of the line decoration indicator is performed for all the lines of the display document selected by the cursor key (steps A18 to A24, A12 to A17 in FIG. 6).

In this way, it is possible to easily confirm the row position where the row decoration is performed from the lighting state of the row decoration indicator.

Next, the print processing operation of the above document will be described.

At the time of printing the document, the document printing is designated by operating the [document printing] key by combining the [function] key and another specific key.

When the CPU 11 discriminates the operation input of the [document print] key, the display mode of the LCD 50 is switched from the document display mode to the print menu display mode. This is shown in FIGS. 7 and 8.

When the CPU 11 discriminates the operation input of the [document print] key, it initializes the count value of the line counter indicating the print line position and then controls the LCD control circuit 17 to display the print menu as shown in FIG. The cursor keys are operated to sequentially and selectively display on the LCD 50 (steps B11 and B1 in FIG. 7).
2). The screen switching and item selection at this time are also performed by cursor key operation in the same manner as the screen switching and item selection at the time of line decoration setting described above. , "Left margin", "Japanese font (24 x 24 dots) / English font (horizontal 18, vertical 24
Screen switching such as "dot") is performed, and the document form of each screen is selected by operating the cursor keys in the left and right directions.
Regarding the setting of "left margin", the digit value is incremented (+1) each time the right direction cursor key is operated, and the digit value is decremented (-1) each time the left direction cursor key is operated. To be done.

When the [select / execute] key is operated after the document form selection operation according to the display contents, the document form setting information is written in the print information holding unit provided in the control information area in the RAM 14.

Next, the CPU 11 sequentially reads the line decoration information in the line attribute buffer 142 from the line decoration information of the first line, and “stops printing”.
After finding the line number to be printed by searching the set line position of, the print processing is executed up to the line position based on the print information of the print information holding unit (steps B13 to B2 in FIG. 7).
1).

Then, when printing is stopped at the line position where "Stop Printing" is set, the above print menu is displayed again, and "Vertical / Horizontal writing", "Left margin", "Japanese / English" etc. The print form can be changed. After setting the print mode, the [Select / Execute] key is operated again,
Printing according to the newly set document form is started from the line position next to the stop line.

Further, when it is detected that the print target document is completed (there is no document in line L + 1) before the setting line of "print stop" is searched, the number of print lines up to the line position is obtained,
The printing process up to the same position is executed (step B in FIG. 7).
13-B15, B22-B24).

At this time, when printing is executed, the message [-printing-] is displayed on the character display digit of the LCD 50. In addition, when executing the above printing, the line attribute buffer corresponding to the print line
According to the contents of the line decoration information in 142, character decoration is optionally performed in units of lines. The contents of each character modification at this time are shown in FIG. 3, and examples of each character font are shown in FIGS. 9 (a) to 9 (e).

In FIG. 9, U indicates an inter-character space, and T indicates a line feed pitch. Further, FIG. 9A shows a full-width (size 1) character string without character decoration, FIG. 9B shows a character string designated to be enlarged (size 3), and FIG. ) Is a full-width character string, the same figure (d) is a full-width character string that is italicized (with italics), and the same figure (e) is a character string that is outlined and enlarged (whitened and size 5). Shows.

In this way, according to the line decoration information stored in the line attribute buffer 142, the character decoration process for each line is executed.

Further, the designation of document storage when the above-mentioned document information is stored on the cassette tape is performed by operating the [save] key by combining the [auxiliary] key and the specific key. CPU11
When the operation input of the above [Save] key is discriminated, the message of [Document save] is displayed on the character display digit of LCD50,
When the input of the [select / execute] key is determined, the saving process is started. That is, when the CPU 11 determines the input of the [select / execute] key, it recognizes that the data recorder 40 is ready for recording. Then, first, when writing the data stored in the RAM 14, the data of the reader unit is output.
That is, here, all "1" data is output for 1 second. After that, the data stored in the RAM 14 is read, converted into bit serial cassette write data, and output. The order of the write data is the line modification information stored in the line attribute buffer 142, the document information stored in the document buffer 141, the external character pattern stored in the external character pattern buffer 143, the registered words stored in the word registration area, and the temporary. The order is the provisional dictionary stored in the dictionary area. Further, after the cassette write data is output, all "0" data is output for 2 seconds as a trailer unit. These data are sequentially transmitted via the PPI 12 and further to the cassette interface circuit 16
After being input to the CMT adapter 41 via the, converted into an analog audio signal, it is supplied to the data recorder 40 and recorded (recorded) on the cassette tape set in the recorder.

The recording format on the cassette tape at this time is the 10th
Shown in the figure.

In this way, the external data recorder 40 stores the line decoration information, the external character pattern, etc., along with the document information.

As described above, printing can be stopped at an arbitrary line position in the document to be printed, and therefore, for example, the number of characters that can be displayed at one time is greatly limited, so a part of the document is printed, checked, or referenced. In the case where it is desired to do so, these can be easily realized by a simple operation. In addition, when the operator wants to change the print form in the middle of printing by a combination of the above-mentioned instruction to stop printing line by line and the setting change of the document form after the stop line, or a certain line position in the middle of printing If you want to change the ribbon color and perform color-coded printing, or if you want to perform multi-column printing, or if you want to shift the printing position from a certain line position in the middle of printing, you can also print vertically and horizontally in each line. Various document modifications can be easily realized with simple operations.
