JPS58144256A - Displaying method of line head positioning inhibited character - Google Patents

Abstract

PURPOSE:To use effectively a display screen by displaying a document to be observed at a glance in case of the suspending processing of a line head positioning inhibited character in a device displaying Japanese documents. CONSTITUTION:A character code of a Japanese document inputted from a keyboard 10 is inputted to a display character discriminating part 171, and when the character code is a general character, the code is sent again to a CRT control part 13 and displayed on a CRT 16. In case of a line head positioning inhibited character, the discriminating part 171 stores the character code and also sends it to a display switching part 175. A display changeover switch signal from the keyboard 10 is detected at its display kind and the detected signal is sent to the display switching part 175. Receiving a cursor position at the operation of a display changeover switch, the display switching part 175 finds and displays OR between an inhibited character pattern and a line end character pattern if the display kind is composite display. In case of inhibited character display, the inhibited character pattern is displayed. In case of line end character display, the line end character pattern is displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a first-in-line character 1 in a Japanese document display device.
This relates to the method of displaying characters.

Generally, when creating a Japanese document, "," is placed at the beginning of the line.
and "." are prevented from appearing.

This type of character/symbol is called a non-first-of-line character.

In conventional Japanese document display devices, if the number of characters in one line of a Japanese document exceeds the number of characters in one line of the display screen,
It is either displayed across rows or by horizontal scrolling left and right. Therefore, in the former case, the number of lines that can be displayed is halved and the effective use of the display screen is impaired because there is only one character that is prohibited at the beginning of a line, and in the latter case, when a prohibited character is displayed by scrolling, the leftmost character is displayed across the entire line. In addition to disappearing from the screen, in both cases there is a gap between the image of the document when it is printed, and the viewability of the displayed document is impaired.

Also, general kanji display devices display characters Fi within one line.
When printing in lead letters on A4 paper with a character size of 10P and a character pitch of % inches, considering the left and right margins,
It is considered optimal to have characters that cannot start a line hanging, and to set the number of characters in one line to 41. Therefore, when constructing a simple Japanese word processor using a general kanji display device, it is a good idea in terms of cost performance to prepare a kanji display device with a display screen that is one order of magnitude larger in order to display one prohibited character. In particular, the above-mentioned drawbacks become noticeable.

An object of the present invention is to eliminate the above-mentioned drawbacks and provide a method for displaying ill characters at the beginning of a line in a device that clearly displays Japanese documents without impairing the visibility of the displayed document or the effective use of the display screen. There is a particular thing.

In order to achieve the above object, in the present invention, when adding and printing one non-first character in a Japanese document at the end of the relevant character, the non-starting character and the last character of the relevant character (the end of the line) are displayed on the display screen. (characters), or the prohibited characters are not displayed and the end-of-line character is highlighted with high brightness.

Hereinafter, the contents of the present invention will be explained in detail with reference to FIG.

FIG. 1r is a block diagram of an embodiment of the present invention.

In FIG. 1, a keyboard 10, a keyboard control $1
1, bus 12, CFLT control unit 13, character generator 14, video controller] 5, C1 (7 etc. 1
Reference numeral 6 indicates a configuration conventionally provided as a Japanese document display device. The no-first-of-the-line character display system # section 17 surrounded by a broken line is a configuration added according to the present invention, and includes a display character determination section 171, a no-first-of-the-line character storage section 172, a cursor position detection circuit 17B, and a no-first-of-the-line character generator 1.
74, display switching section 175, display switching signal detection circuit 176
, synthesis output section 17? It becomes more.

The operation of FIG. 1 is as follows. The character code of the Japanese document input from the keyboard 10 is input to the keyboard control unit 1.
1, enters the display character judgment unit 171 together with the display address via the bus 12 and the CRT control unit I3. If the input character code is a general character, the display character determination section 171 resends it to the CRT control section 13. The operation in this case is the same as the conventional one, and under the control of the CRT control section 13, the dot character corresponding to the input character code is read out from the character 7 generator card 1, and the dot character is read out from the character 7 generator 1, and the dot character is read out from the character 7 generator 1 under the control of the CRT control section 13. , are displayed on the CRT 16 through the video controller. On the other hand, if the input character code is a non-startable character, the display character judgment $ 171 stores the character code in the non-startable character storage section 172 (display switching section 1
Send to 75.

Keyboard IO includes a display changeover switch,
The signal from the display changeover switch enters the display changeover signal detection circuit 176 via the keyboard control unit 11, where the display changeover signal detection circuit 176 detects the display changeover of composite display, prohibited character display, and end-of-line character display. be done.

The display gJ switching section 175 obtains the cursor position when the display changeover switch is operated from the cursor position detection circuit 17B, and if the display type is "synthetic display", the displayed character judgment section 171
The synthesis output unit 177 sends the non-startable character code sent from the character generator 174 to the non-startable character character generator 174 to obtain the non-startable character pattern, and then logically ORs this with the end-of-line character pattern from the character generator 14 and outputs the result. Sends control signals to. In addition, the display switching section 175
Then, if the display type is 1 - Inhibited character display, then the prohibited character code is read from the prohibited character storage section 172 at the beginning of the line,
The synthesized output unit 17 sends a character that cannot start a line to the character 7 enerator and outputs the prohibited character ・; turn, and ignores the input from the character 7 enerator 14.
7: Sends two control signals, and if the display type is "end-of-line character display," sends a control signal to the synthesis output unit 177 so as to ignore the human power from the character generator 174 for characters that cannot start the line.

An example of a Japanese document displayed using the device shown in Figure 1 is shown in Figure 8.
As shown in the figure. In Fig. 8, it is a printing image of an i-U Japanese document, and if you want to print one character of the printing image 7 that cannot be displayed at the beginning of a line on the corresponding line, but the number of characters that cannot be displayed in one line exceeds the maximum number of characters displayed on the display screen, 2 As shown in the display screen image /, by displaying a character that cannot start a line and the end-of-line character, the visibility of the entire document can be maintained. In addition, when correcting a character that cannot be started at the beginning of a line or a character that cannot be started at the end of a line, by operating the display changeover switch on the keyboard, as shown in the display screen images shown in 8 and 4, only the character that cannot be started at the beginning of the line specified by the cursor or the corresponding Only the end-of-line character can be displayed individually.

FIG. 2 shows Block 1'J of another license of the present invention, in which a line-inhibited character control unit 21 is added to a general Kanji display device (9), and instead of combining the line-inhibited characters with the line-end characters ( 2. The character at the end of the line is highlighted. In FIG.
212, a display character determination section 21B, a cursor position detection circuit 214, a display switching section 215, and a kanji display interface circuit wi216.

The operation of FIG. 2 is as follows. The character code of the Japanese document to be displayed on the kanji display device is input to the display character determination section 213 together with the display address via the interface circuit 216. In the display character judgment unit z13, if the input character code is a character that cannot be started at the beginning of a line, it is stored in the character storage unit 211 for characters that cannot be started at the beginning of a line, and if it is a general character, it passes through the display switching unit 215 and is converted into a kanji character via the interface circuit 216. Resend to display device. Further, when the display character determining section 218 detects Vl, a character that cannot be started at the beginning of a line, it sends a control signal to the display switching section 215 to highlight (high brightness, plink, etc.) the end-of-line character. Display switching section 21
5, upon receiving the control signal from the display character determination section 213, it sends an emphasis display signal to the kanji display device via the interface circuit 216 for the end-of-line character.

The display switching operation is detected by the display switching signal detection circuit 212, and the cursor position at the time of the operation is detected by the cursor position detection circuit 2.
14, and both are sent to the display switching unit 215. With this display switching operation, the display switching unit 215 reads the corresponding prohibited character from the line-inhibited character storage unit 2117+, and replaces the line-end character outputted via the kanji display interface circuit 216 with the prohibited character, It is sent to a kanji display device and displayed.

An example of a Japanese document displayed using the device shown in Figure 4 is shown in Figure 4.
As shown in the figure. In Figure 4, ■ is a printed image of a Japanese document, and when displaying this, characters that cannot be started at the beginning of a line are not displayed, and characters at the end of the line are highlighted with high brightness, etc. By doing this, you can display the entire document without compromising its visibility. In the case of correction of characters that cannot be started at the beginning of a line, as shown in the display screen image 3, by operating the display changeover switch, the characters that cannot be started at the beginning of a line specified by the cursor can be replaced with characters at the end of the line.

As explained above, according to the present invention, when configuring a simple Japanese word processor using a dedicated Japanese document display device or a general Kanji display device, the maximum number of characters in one line on the display screen can be exceeded. When creating a Japanese document that processes non-first-line characters, it is possible to display the document while retaining the -f property, which has the advantage of making effective use of the display screen.
