Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a character processing device for processing characters, symbols, numbers, etc., such as a word processor device or an electronic computer.

<Prior art> Devices that handle European and American languages use high-quality fonts (Pica, Elite, Gothic, etc.) is required to be output, so the configuration uses printing methods such as daisy wheels and crowns, but this limits the types of characters, so of course if different fonts are used, the same Even in fonts, if there are many types of characters used, one daisy wheel or crown cannot accommodate all the types of characters.

Conventionally, when character data other than the corresponding character data set on an output device such as a printer is output, the output device ignores the character data and outputs it with a space or special character instead. Otherwise, the output was to be stopped at that point and the operator's instructions were to be suppressed (for example, a message was to be output such as whether to reset the daisy wheel with output characters, the crown, or to skip).

<Object of the Invention> In view of the above-mentioned matters, the present invention provides a character processing device that makes it possible to eliminate in advance the above-mentioned reason for interrupting output at the time of output.

<Example> Hereinafter, the structure of the present invention will be described together with examples.

As shown in FIG. 1, the keyboard of the character processing device according to the embodiment of the present invention is normally in an undetermined key arrangement state.

As shown in Figures 5a and 5b, the character codes are predetermined, and the operator selects and sets the character code to be used at any position on the keyboard using the control code to determine the key arrangement of the keyboard. be. Specifically, FIG. 2 shows a keyboard with keys arranged for English, FIG. 3 shows a keyboard with keys arranged for German, and FIG. 4 shows a keyboard with keys arranged for French.

In this way, the character processing device of this embodiment grasps the code information input from the keyboard and generated as position information, not as character information, and converts it into the original character information code from the parameter table existing in the storage device. Then, subsequent language processing is performed.

FIG. 6 shows the block configuration of this embodiment.

In the figure, 1 is an input/display device, 2 and 4 are registers, 3 and 6 are tables, 5 is a storage device,
7 is an output device and 8 is a control device.

The input/display device 1 is for inputting character/word information data into the storage device 5, and notifies the register 2 of the positional information of the keys arranged at which inputs are made. Furthermore, the information in tables 3 and 6 is displayed on the CRT.

The register 2 is for storing position information generated from the input/display device 1, and the table 3 stores information for converting the position information input into the register 2 into character information specified by the operator in advance. Information about the daisy wheel or crown specified by the operator is stored.

The character information selected in the register 2 and the table 3 is stored in the register 4.

The storage device 5 stores character information passing through the input/display device 1, the registers 2, 4, and the table 3, and also selects which daisy wheel or crown character type in the table 6 from time to time in relation to the table 6. Then, check whether the print output can be processed without stagnation. This inspection, that is, the inspection means, compares the character information in the storage device 5 with the table 6 at any time, and can select and instruct a specific character font for printing.

In the table 6, the information in FIG. 13 a, b, c, and d is stored according to the font used, such as daisy foil or crown, and as shown in the figure, printable characters and non-printable characters are stored. It is stored in such a way that it can be recognized, and is used to check the character data stored in the storage device 5.

The output device 7 outputs the results saved and edited in the storage device 5, and the control device 8 controls the exchange of signals between the components 1-7.

Here, the actual work performed by the operator using the character processing apparatus of this embodiment will be explained.

The operator corrects the data in Table 3 before performing language processing. In a normal key interface, the position information of the key code (shift in, shift out, alphanumeric, kana) and information on whether the control (Control) and ALT (Function) keys are pressed are displayed. Using these, the character code in the corresponding table area is extracted. This will be explained in detail using FIG. The condition flag in the left column of the figure indicates whether to use the code table in Figure 5a or the code table in Figure 5b when each mode (Normal, Control, ALT mode) is pressed. This is a discrimination flag. or,
The condition flag in the right column of the figure is the ON/OFF flag of the character information in the daisy wheel specified in Table 6 above. This is activated when instructed by the operator, and if the daisy wheel set on the output device is set to a specific one, if the corresponding bit of this condition flag is turned on, if a character that is not turned on is used, it will be irregular. For example, display the information externally using a buzzer or prompt information.

In the case of the same figure, if the condition flags are the same,
Position code 00H (H represents Hexadecimal)
If you press the key, you can retrieve the same 52H code. Furthermore, if the condition flag is 000000, the character "Δ e" information can be retrieved since the information is 00 mode 52H regardless of whether the mode is normal, control, or ALT. However, the condition flag is 000100.
Then, in normal mode and ALT mode, character "Δ e" information can be extracted, but in control mode, character "<" information can be extracted. or,
If the location information is FF, if the flag is 00,
The information is the letter "S" in normal mode, the letter "T" in control mode, and the letter "U" in ALT mode.

The operator can display unusable character information or usable character information on the screen by inputting an instruction. For example, as shown in Figure 9,
The CRT screen of the input/display device 1 is divided into two parts, upper and lower, and the upper screen stores the current input data and the storage device 5.
The character information stored in the daisy wheel is displayed, and only the characters corresponding to the currently set daisy wheel are displayed in reverse (indicated by ⓓ in the figure).

In addition, just before outputting, it is determined which daisy wheel should be set according to the style information of the text to be outputted, using the character information stored in the storage device 5 and the table 6 as explained earlier. By comparing from time to time, it is also possible to select the most suitable daisy foil and display it on the screen. In other words, as shown in Figure 8, styles are specified in advance by character spacing pitch and by medium classification, and the operator's instructions are suppressed at the time of output. The structure is such that a message is displayed to see if the effort of resetting the easy wheel can be saved.

The names in the right column of FIG. 8 refer to a collection of character type information, and as specific examples, Elite is shown in FIG. 10, Courier72 is shown in FIG. 11, and Pica10 is shown in FIG. 12.

Additionally, the table 6 stores the information shown in FIG. 8 and the information shown in FIGS. 10 to 12. The content area can be changed from the input means (input/display device 1) similarly to Table 3 above. By setting and managing the areas of the tables 3 and 6, the effort of outputting character information can be greatly reduced.

<Effects> As explained above, according to the character processing device of the present invention, it is possible to determine whether or not the characters are usable during character input, and which daisy wheel, etc., is set when the text creation is finished. This is very convenient because it also provides instructions on whether the output work can be executed without stagnation.

In particular, by displaying whether printing is not possible or not, the operator does not have to input characters that cannot be printed, and it is also possible for the operator to prevent character input errors caused by stopping printing midway through printing.
