Here, the screen is switched by operating the cursor keys in the vertical direction (up, down), and selecting items (specifying selected items with the cursor) by operating the cursor keys in the horizontal direction (left, right). To switch the display to this line modification screen, actually press and hold the function key [, -1-1
The line modification display mode is specified by pressing the [II] key, but in order to simplify the explanation here, the combination key operation for specifying the line modification display mode described above is simply input as the line IEI. ! This is called iii key operation. In addition, when setting the above line IIMrs, by updating the selection screen using the up and down cursor keys, item selection on the selection screen before the update is completed (cursor -
The line decoration information is written into the line attribute buffer 153, assuming that the item at the position has been selected) and that the selection/execution key has been pressed, thereby completing the line decoration setting. In addition, in the above line decoration display mode, if it is not selected, it is in the selected state set in the format settings or the state set in full text deletion [for example, the cursor (diagonal line) position state shown in the diagram]. Each setting value is referred to as a row modification standard value here.

It is possible to set the English font (horizontal 18 x 124 dots).

FIG. 9 shows various character forms set in the above line decoration settings. In the figure, U indicates the character spacing, and King indicates the line pitch.

Next, the operation in such a configuration will be explained.

When inputting a sentence containing kanji, the key input signal from the keyboard 14 is converted into kana and kanji characters under the control of the CPU 11, and stored in the document buffer 152 in the RAM 15. That is, the CPU 11 outputs a scan signal to the keyboard 14 via the interface circuit 12 and decoder 13, receives the return signal via the interface circuit 12, performs key manual force determination, and generates a key code. Then, by indexing the dictionary in the ROM 16 and furthermore the provisional dictionary in the RAM 15 for the designated part of the kanji that has been input into kana based on the key code, the converted kanji code is converted into kana and kanji. The input character code string containing the document buffer 152
It is something to be stored in. At the time of inputting the above-mentioned document, the input characters stored in the document buffer 152 are
The pattern is sequentially developed on the row image buffer 151 under the control of
A maximum of 9 digits are displayed on top of 0. The inputted document thus input can be arbitrarily displayed as a character string of up to nine characters on the liquid crystal display 20 by operating the cursor keys, and can be used for proofreading or correction of the document.

If you want to perform various character modifications such as rotation, italics, outline, font size, line feed pitch, character spacing, etc., or specify printing stop for the above input text on a line-by-line basis,
The character string at the line position to be modified is selected and displayed using the cursor keys, and the line modification is specified by operating the row modification key in combination with the function key and other specific keys. CPU
11 switches the display mode of the liquid crystal display 20 from the document display mode to the line modification display mode when determining the operation input of this line modification key. 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. Here, a selection screen for selecting the character amount interval is first displayed.

In this line modification display mode, the screen is switched to a selection screen 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 a selection screen for selecting whether to use white outline is displayed, if you do not select an item using the left/right cursor keys and switch the selection screen using the up/down cursor keys, the selection screen will be displayed. Assuming that the content at the selected item position displayed by the cursor has been selected, the next item on the newly displayed selection screen becomes the selection target.

Display the selection screen for "with/without white outline" by switching the selection screen above, use the cursor keys to move the cursor to change the setting with/without white outline, and then switch the selection screen or press the select/execute key. By the operation, line modification information having selection information of the presence/absence of white outline whose settings have been changed is stored in the line attribute record 4a area corresponding to the selected line position in the line attribute bag 7153. In addition, by switching the selection screen above, display the selection screen for "Printing stop", move the cursor using the cursor keys and select "Printing stop",
Thereafter, by operating the selection/execution key, line modification information having the control information "printing stopped" is stored in the corresponding line attribute storage area in the same manner as described above. FIG. 13 shows the correspondence between the line attribute buffer 153 and the document buffer 152 and the setting contents of the line modification information at this time.

In the above-described line modification settings, after new line modification settings have been made for any line position of the document stored in the document buffer 152, the previously inputted document in the document buffer 152 can be displayed on the liquid crystal display 20 by operating the cursor keys. By displaying the character string, the line and digit of the displayed character string and the number of characters per line are displayed on the guide display section on the liquid crystal display 20, and a line modification indicator and a battery consumption indicator are also selectively displayed. Ru. The guide display form at this time is shown in FIG. 5, and the lighting control processing procedure of the row modification indicator is shown in FIG.

That is, the lighting 11 of the row modification indicator shown in FIG.
In i1j lit processing, when a display character string is selected by operating a cursor key, the line position, column position, and number of characters per line of the display character string specified by the cursor are displayed, and are stored in the line attribute buffer 153. The line decoration information of the corresponding row position is referenced, and the line decoration information is compared with the line decoration standard value to determine whether or not line decoration is set for the display line selected by the cursor. (Steps A11 to A15 of the 6th cause)
.

Here, if line decoration is not set, that is, if the contents of the above line decoration information match the line decoration standard value, the line decoration indicator will not be lit, and if line decoration is set, that is, if the above line decoration information matches the line decoration standard value, then If the content of the row modification information does not match the row modification standard value, the row modification indicator is turned on (step Al6.A17 in FIG. 6). Such display control of the line modification indicator is performed for all lines of the displayed document selected by the cursor keys (steps A18 to A24 and A12 to A17 in FIG. 6).

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, document printing processing operations will be explained.

When printing a document, document printing is designated by operating a document print key using a combination of a function key and another specific key. When the CPLIII determines the operation input of the document print key, it switches the display mode of the liquid crystal display 20 from the document display mode to the print menu display mode. The situation is shown in FIGS. 7 and 8. C.P.
When tJll determines the operation input of the document print key, it initializes the count value of the line counter indicating the print line position, and then displays the print menu as shown in FIG. 8 by controlling the display III 'IIJ circuit 19. are sequentially and selectively displayed on the liquid crystal display 20 in accordance with cursor key operations (steps B11 and B12 in FIG. 7). Screen switching and item selection at this time are also performed by operating the cursor keys in almost 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 on each screen is selected by operating the left and right cursor keys. In addition, regarding the "left margin" setting, each time you operate the right cursor key! The row value is incremented (+
1), and each time the left cursor key is operated, the digit value is decremented (-1). After the document format selection operation according to the above display contents, the selection/execution key is operated to write this document format setting information into the print information holding section provided in the control information area in the RAM 15.

Next, the CPU 11 sequentially reads the line modification information in the line attribute buffer 153 starting from the line modification information of the first line, searches for the line position where "print stop" is set, and determines the number of lines to be printed. After determining , print processing is executed up to that line position based on the print information in the print information holding section (steps 813 to B21 in FIG. 7). Then, when printing stops at the line position set for "Print Stop", the above print menu will be displayed again, and after the above stop line, "Vertical A1 Horizontal", "Left Margin", "Japanese, English" etc. The printing format can be changed. Further, after setting the print format, by operating the selection/execution key again, printing processing according to the newly set document format is started from the line position next to the above-mentioned stop line. Additionally, if it is detected that the document to be printed has ended (there is no document on line L+1) before the above "Print Stop" setting line is searched, the number of lines to be printed up to that line position is calculated, and Print processing up to the line position is executed (steps 813 to 815, 822 to B24 in FIG. 7). At this time, when printing is executed, a message "-Printing in progress" is displayed in the character display column of the liquid crystal display 20.

Further, during the above-described printing, 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 153 corresponding to the print line. The content of each character modification at this time is shown in FIG. 3, and an example of each character font is shown in FIG. In Figure 9, (a) is a full-width (size 1) character string without character modification, (b) is a character string specified for enlargement (size 3), and (C) is a specified rotation (rotation 2 - 180 degrees). ), (d) shows a full-width character string specified in italics (with italics), and (e) shows a character string with outline and enlargement (with outline, size 5). In this way, the row attribute buffer 15
Various row modification processes are executed on a row-by-row basis according to the row modification information stored in 3.

Next, a document storage processing operation for storing the above-mentioned document information in an IC card having a built-in microprocessor and memory will be described. At the time of document storage, document storage is specified by operating a document storage key using a combination of an auxiliary key and another specific key. In this case, after performing the above document save key operation, the ID code (
Enter the password (password) and file name, then press the Select/Execute key. When CPLll 1 determines the ID code, file name, and document save key operation input,
A message "Document save" is displayed on the character display column of the liquid crystal display 20, and when the subsequent selection/execution key operation input is determined, the document save process is started. In other words, CPU1
1, upon determining the operation input of the selection/execution key, transmits the input [D code] to the IC card 26 via the interface circuit 17 and the IC card reading/writing device r1118 as serial data. The IC card 26 compares the transmitted ID code with the ID code stored in advance, and when the two ID codes match, it sends the IC card reading/writing device W1 to the CPU.
18 and the interface circuit 17, the match completion data is returned as serial data. When the CPU 11 receives the match completion data, the CPU 11 connects the IC card 26 to the interface circuit 17 and the IC card reading/writing device W/118.
The write command is transmitted as serial data via the .

When the IC card 26 receives the write command, the CPLJ
A ready signal is returned as serial data to the IC card reading/writing device @18 and the interface circuit 17. When the CPU 11 receives the ready signal, the IC
Q! Is the writing preparation for card 26 completed? do. Then, the CPU 11 uses the input file name and R
It is converted into IC card write data in AM15 and output. The order of this write data is: line modification information stored in the line attribute buffer 153, document information stored in the document buffer 152, custom character pattern stored in the custom character pattern buffer 154,
The registered words and phrases stored in the word/phrase registration area are followed by the provisional dictionary stored in the provisional dictionary area. This output data is transmitted to the IC card 26 via the interface circuit 17 and the IC card reading/writing device 18, and written into the memory within the IC card 26.

An example of the transmission format for the IC card 26 at this time is shown in FIG. This transmission format is
As shown in Figure 0 (a), the order consists of the start code (STX), message length, command, data, and end code (ETX). For example, when transmitting an ID code, the data part is the ID as shown in Figure (b). When transmitting the file name and write data, the data portion becomes the file name, sequence number, and document information as shown in FIG. 2(C).

Next, the document successive processing operation for reading document information stored in the IC card 26 as described above will be explained. At the time of document reading, the document readout is designated by operating the word successive key in combination with the auxiliary key and another specific key, as in the case of document storage. In this case, the person who operated the word succession key, the user, enters the ID code and file name, and then operates the selection/execution key. When the CPU 11 determines the ID code, file name, and operation input of the document reading key, the CPU 11 displays the message "Text II Read" on the character display digit of the liquid crystal display 20, and when the CPU 11 determines the operation input of the selection/execution key that follows, displays the message "Text II Read". 1. Start read processing.

That is, when the CPU 11 determines that the selection/execution key is operated, the CPU 11 transmits the input ten codes to the IC card 26 via the interface circuit 17 and the IC card reading/writing device 18 as serial data.

The IC card 26 compares the transmitted ID code with 10 codes stored in advance inside the IC card 26, and if both 10 codes match, the IC card reader/writer 18 and interface circuit 17 are sent to the CPU 11. The match completion data is returned as serial data via the . C
When the PU 11 receives the match completion data, the IC card 2
The successive commands are transmitted as serial data to the IC card 6 via the interface circuit 17 and the IC card reading/writing device 18. When the IC card 26 receives the successive commands, it sends the IC card reading/writing device RA18iB to the CPU 11.
and the ready signal is returned as serial data via the interface circuit 17.

When the CPIJll receives the ready signal, the IC card 2
Recognizing that the preparation for the continuation of 6 has been completed, the input file name is transmitted to the IC card 26 via the interface circuit 17 and the IC card reading/writing device 18.

The IC card 26 reads the document information corresponding to the transmitted file name from the memory and sends it to the CPU via the IC card reading/writing device 18 and the interface circuit 17.
11. The CPU 11 stores the transmitted document information in the RAM 15 and prepares for processing such as document editing, proofreading, and printing.

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, especially in a low-cost and compact document creation device with a small number of display character digits. In addition to being able to easily recognize the line position where the line modification has been made, it is possible to easily set and change any document format including outline characters for any line, and also to easily recognize the line position where the line decoration is applied. 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 you want to print, check, or refer to a part of the document because the number of characters that can be displayed at one time is severely restricted. , these can be easily realized with simple operations. In addition, by combining the above line-by-line printing stop instruction and changing the document format settings after the stopped line, if the operator wants to change the print format in the middle of printing, or print from a certain line position in the middle of printing, If you want to print each color by changing the color of the ribbon, or if you want to perform multi-column printing, or if you want to shift the printing position from a certain line position during printing, or if you want to print vertically or horizontally by line. Various document modifications such as mixed printing can be easily realized with simple operations.

Furthermore, since an IC card is used as a document file, its read/write capacity is considerably smaller than that of a microfloppy disk device, and the configuration is simple, making it possible to achieve even smaller size, lighter weight, and lower cost. becomes. Furthermore, since an IC card has a much smaller electrical load than a micro-floppy disk device or the like, it can consume less power and is especially advantageous when driven by batteries. Furthermore, by assigning a 10 code to the IC card, the contents cannot be easily read, and the confidentiality of the document file can be sufficiently increased.

[Effects of the Invention] As detailed above, according to the present invention, smaller size, lighter weight,
It is possible to provide a document creation device that is low in price and consumes little power, and also provides sufficient confidentiality of document files.
