Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a document creation device having a line modification function.

[Technical background of the invention and its problems] Conventionally, document creation devices such as Japanese word processors use a CRT display as a document display mechanism and an external storage such as a floppy disk device as a document file mechanism. The structure was large and expensive. However, in recent years, various innovations and improvements have been made, such as using an LCD (liquid crystal display) for the display mechanism and a CMT (cassette magnetic tape device) for the document file mechanism, and small, lightweight, and low-cost devices have been realized. I have reached the point where

In such low-cost and compact document creation devices, for example, there are major constraints on the display screen size of the LCD that serves as the input mechanism, and it is necessary to use a small screen size of 1 to 2 lines and 10 characters. things are used.

In a low-cost and compact document creation device that is limited by its input and output mechanisms, it is important to know how to effectively use its input and output mechanisms to create highly functional, multi-functional, and easy-to-use devices. The big question is whether to realize the device.

For example, in conventional low-cost and compact document creation devices of this type with a small number of display character digits, it is possible to perform rotation, italicization, whiteout, font size, line break pitch, character amount, etc. in units of arbitrary lines. It does not have the ability to set various character modifications such as spacing.

For this reason, in the past, the document format was changed by rotating/italicizing, whitening, character spacing, etc. for each line, or mixed printing was performed by combining various characters including whiteout characters. However, this cannot be achieved easily with simple operations.

Conventionally, when trying to provide the above-mentioned character modification function in a low-priced and compact document creation device with a small number of display character digits, the amount of internal memory increases due to the increase in functions, and the key Due to the expansion of peripheral trowel structures, etc., it has become difficult to achieve compactness, weight reduction, and cost reduction. It was difficult to realize this.

[Object of the Invention] An object of the present invention is to provide a document creation device with a practically advantageous configuration that can be made compact, lightweight, and low-priced while also being highly functional and multifunctional. .

[Summary of the Invention] The present invention provides a low-cost and compact document creation device with a small number of display character digits, which includes at least a processing device that handles document editing/proofreading processing and input/output control, and a plurality of channels. an integrated circuit device having a peripheral control circuit section mounted on the same chip; and a configuration in which a peripheral device including at least a keyboard is connected to the peripheral control circuit in the integrated circuit device via an input/output channel of the circuit.

After that, the bit serial cassette write data (line modification information/document information/external character pattern/registered words/phrases/temporary dictionary, etc.) output from the PP112 is written, and then approximately 2 All seconds''
Data of 0'' is written.

Here, the operation of one embodiment will be explained with reference to the above figures.

When inputting a sentence containing kanji, the key input signal from the keyboard 30 is converted into kana and kanji under the control of the CPU 11 in the 8110, and is stored in the document buffer 141 in the RAM 14. At this time, CP LJ 11
A scan signal is output to the keyboard 30 via the PP 112 and further via the decoder 13, and the return signal is sent to the PP.
112 is input to perform key discrimination and generate a key code. Furthermore, the dictionary in the ROM 15, and furthermore the RAM
14, and after performing kana-kanji conversion processing, the input character code string including the converted kanji code is stored in the document buffer 141.

When inputting the document mentioned above, is there a document buffer? The input characters stored in 141 are sequentially developed into patterns on the line image buffer 140 under the control of the CPU 11.
The display control of the CD tRm circuit 11 and the display drive of the LCD driver 51 output a maximum of nine digits for display on the LCD 50.

The already inputted document thus input can be arbitrarily displayed as a character string of up to nine characters on the LCD 50 by operating the cursor keys, and can be used for proofreading, correction, etc. of the document.

For the above input document, rotate, italicize, line by line,
If you want to make various character decorations such as whiteout, character size, line feed pitch, character spacing, or specify printing stop, use the cursor keys to select and display the character string at the line position you want to modify, and then click [Function] Line modification is specified by [Line Modification 1] key operations in combination with the key and other specific keys.

When the CPU it determines that the [line modification] key is operated, it switches the display mode of the LCD 50 from the document display mode to the line modification display mode. The situation is shown in Figure 4. FIG. 4(a) shows the display state in the document display mode, and FIG. 4(b) shows the initial display state after switching to the line modification display mode by operating the [Line modification] key. . Here, a selection screen for selecting the character amount interval is first displayed.

In this line modification display mode, the selection screen is switched by operating the cursor keys in the up and down directions, and items are selected by specifying the cursor by operating the cursor keys in the left and right directions.

For example, when the selection screen for selecting the presence or absence of white outline is displayed, if you do not select an item by operating the left/right cursor keys and switch the selection screen by operating the up/down cursor keys, the above selection screen Assuming that the contents of the selected item position where the cursor is displayed are selected,
Next, the items on the newly displayed selection screen become the selection targets.

Display the selection screen for "Without white outline" by switching the selection screen above, change the setting with white outline by moving the cursor using the cursor keys, and then switch the selection screen, or press the [Select/Execute] button. By operating , line modification information having selection information of the presence/absence of white outline whose settings have been changed is stored in the line attribute storage area corresponding to the selected line position in the line attribute buffer 142 . Also, by switching the above selection screen to display the "Print Stop" selection screen, move the cursor using the cursor keys to select "Print Stop", and then press the [Select/Execute] key. , line modification information having control information of "printing stopped" is stored in the corresponding line attribute storage area in the same way as described above. FIG. 3 shows the correspondence between the line attribute buffer 142 and the document buffer 141 and the setting contents of the line modification information at this time.

In the above line decoration setting means, the document buffer 141
If a new line modification setting has been made to an arbitrary line position of a document stored in The line and digit of the displayed character string and the number of characters per line are displayed on the guide display section of the screen, and a line modification indicator and further 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 for the row modification indicator is shown in FIG.

That is, in the lighting control process of the line modification indicator shown in FIG. 6, when a display character string is selected by cursor operation,
The line position and column position of the display string specified by the cursor,
and the number of characters per line are displayed, and the line modification information of the corresponding line position stored in the line attribute buffer 142 is referenced, and the same information is compared with the standard value of line modification, and the information selected by the cursor is It is determined whether line decoration is set for the displayed line (steps A11 to A in FIG. 6).
15).

Here, if the line decoration is not set, that is, if the content of the above line decoration information matches the above line decoration standard value, the line decoration indicator will not be lit, and if the line decoration is set, i.e. If the content of the line modification information does not match the line modification standard value, the line modification indicator is turned on (steps A16 and A17 in FIG. 6).

Such display control of line modification indicators is performed for all lines of the displayed document selected by the cursor keys (steps A18 to A24 and A12 to A in FIG. 6).
17).

In this manner, the line position where the line modification has been performed can be easily confirmed from the lit state of the row modification indicator.

Next, the printing processing operation of the above-mentioned document will be explained.

When printing this document, document printing is specified by operating the [Document Print] key using a combination of the [Function key and another specific key].

When the CP LJ 11 determines that the [document print] key has been operated, it switches the display mode of the LCD 50 from the document display mode to the print menu display mode. The situation is shown in FIGS. 7 and 8.

When the CPU 11 determines that the [Document Print] key is operated, the CPU 11 initializes the count value of the line counter indicating the print line position, controls the LCD control circuit 17, and prints the eighth

311.312). The screen switching and item selection at this time are performed by cursor key operation in the same way as the screen switching and item selection during the line modification setting described above. , "Left margin", "Japanese font (24 x 24 dots)/English font (18 horizontal x 24 vertical dots)", etc., and the document format for each screen can be changed by operating the left and right cursor keys. selected. Regarding the "left margin" setting, each time the right cursor key is operated, the digit value is incremented (+1), and each time the left cursor key is operated, the digit value is decremented (-1). be done.

After the document format selection operation according to the above display contents, by operating the [Select/Execute] key, this document format setting information is written to the print information holding section provided in the control information area in the RAM 14. .

Next, the CPU 11 sequentially reads the line modification information in the line attribute buffer 142, starting with the line modification information of the first line, searches for the line position where "print stop" is set, and calculates the number of lines to be printed. Then, based on the print information in the print information holding section, print processing is executed up to that line position (step 813 in FIG. 7).
~B21).

When printing stops at the line position where "Print Stop" is set, the above print menu will be displayed again, and the settings such as "Vertical/Horizontal", "Left Margin", "Japanese/English", etc. after the stop line will be displayed. It becomes possible to change the printing format.

Further, after setting the print format, by operating the [Select/Execute] key again, printing according to the newly set document format is started from the line position next to the above-mentioned stop line.

In addition, if it is detected that there is no text in line L+1 to end the document to be printed before the above-mentioned "stop printing" setting line is searched, the number of lines to be printed up to that line position is calculated,
Execute the printing process up to the accompanying position (Step 8 in Figure 7)
13-815.822-B24).

At this time, when printing is executed, the message [-Printing-] is displayed in the character display column of the LCD 50. or,
When printing is executed, character decoration is optionally performed on a line-by-line basis according to the contents of the line decoration information in the line attribute buffer 142 corresponding to the print line. 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 (e).

In FIG. 9, U indicates the character spacing, and O indicates the line feed pitch. In addition, (a) in the same figure is a full-width (size 1) character string without character modification, (b) is a character string with enlargement specified (size 3), and (C) is a character string with rotation specified (rotation 2). -1
80°) full-width character string, the figure (d> is a full-width character string specified in italics (with italics), the same figure (e) is a character string specified with outline and enlargement (with outline, size 5) are shown respectively.

In this manner, various row modification processes are performed on a row-by-row basis according to the row modification information stored in the row attribute buffer 142.

Further, when saving the above-mentioned document information on a cassette tape, document storage is specified by operating the [save] key in combination with the [auxiliary] key and the specific key. c p
When u 1i determines that the [Save] key has been input, it displays a message for document storage on the character display column of the LCD 50, and when it determines that the [Select/Execute] key has been input, it starts the storage process. That is, when the CPU 11 determines that the [selection/execution] key is input, the CPU 11 executes the data recorder 40.
01 indicates that the recording single tooth has been completed. And first, R
When writing data stored in AM14, data from the reader section is output. That is, here, data of all "1" is output for one second.Then, the data stored in the RAM 14 is read out, converted to pit serial cassette write data, and output.The order of this write data is determined by the line attribute. Line modification information stored in the buffer 142, document information stored in the document buffer 141, custom character patterns stored in the custom character pattern buffer 143, registered words stored in the phrase registration area, provisional information stored in the provisional dictionary area In addition, after outputting this cassette write data, all "0" data is output for 2 seconds as a trailer section.These data are sequentially sent to the CMT adapter via the PP 112 and further via the cassette interface circuit 16. 41 and is converted into an analog audio signal, then supplied to a data recorder 40 and recorded (recorded) on a cassette tape set in the recorder.

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

In this way, line modification information, external character patterns, etc. are stored in the external data recorder 40 along with document information.

By having a line modification function including the line modification indicator as described above, it is possible to easily add various line modification information to any line position in a low-cost and compact document creation device with a small number of display characters. In addition to being able to
You can easily recognize the line position where some-line modification has been made, and this allows you to easily set and change any document format, including outline characters, for any line, and also allows you to easily set and change any document format, including outline characters, for any line. Mixed printing can be easily performed.

In addition, printing can be stopped at any line position in the document to be printed, so for example, if the number of characters that can be displayed at one time is severely restricted, you may want to type out a part of the document to check or refer to. These can be easily realized with simple operations. Also, by combining the above-mentioned line-by-line printing stop instruction and changing the document format settings for the line after that stop line, if the operator wants to change the print format during printing, or if the If you want to print by changing the print ribbon color based on the position, or if you want to perform multi-column printing, or if you want to shift the printing position from the line position where it is in the middle of printing, or if you want to print vertically or horizontally in units of lines. Various document modifications such as mixed printing can be easily achieved with simple operations.

In addition, within the 8110, there is a CPLJll that controls the entire device.
By providing a peripheral control circuit including at least one PP 112 and connecting a keyboard 30 and a data recorder 40 using a cassette magnetic tape device to a common channel of the PP 112, the overall connection configuration of the device can be changed. It can be significantly simplified and miniaturized, and the PP112
