Abstract

PURPOSE:To attain the continuous input of a document including different sizes of characters and to improve the operability of a character processor by analyzing the input character information and switching automatically an optimum character size input mode. CONSTITUTION:In a half-sized mode the input character code of a keyboard KB is analyzed and the automatic half-sized processing is started when the character code shows an alphanumeric character. That is, a mode setting means (microprocessor CPU) analyzes the input adjacent character information and at the same time sets automatically an optimum character size (half-sized mode) when the character information are successively inputted. Under such conditions, the generation of a character pattern of a desired size (half-sized mode) corresponding to the input character information is controlled based on the character size mode set automatically by a pattern generation control means (microprocessor CPU). Thus a character pattern of a half size that is optimum to the input character information is obtained.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device that can change the character size of each character of input character information.

[Prior Art] Conventionally, this type of device is configured to display characters generated by a character generator in response to character information input from a keyboard or the like, so that a desired document can be created.

In particular, when changing the font size, it was necessary to change the font size mode (full-width, half-width, etc.) and input character keys.

Alternatively, after inputting characters, specify the range of character strings whose font size has been changed, and use the font size setting process key to manually change the font size of the specified range of character strings. was.

[Problems to be Solved by the Invention] However, according to the conventional font size changing process described above, when changing the font size, it is necessary to temporarily suspend the previous character input work and perform the font size changing process.

However, there were problems such as being forced to change the font size mode each time.

This invention was made to solve the above problems, and by analyzing input character information and automatically switching the optimal font size input mode, it is possible to continuously process documents with mixed font sizes. An object of the present invention is to obtain a character processing device that allows input and has excellent operability.

[Means for Solving the Problems] A character processing device according to the present invention includes a mode setting means for automatically setting an optimal character size mode while sequentially manually inputting adjacent character information, and this mode setting means. A pattern generation control means is provided for controlling generation of a character pattern of a desired size corresponding to input character information based on a character size mode automatically set by.

[Operation] In the present invention, when character information is manually entered one after another, an optimal character size mode is automatically set after analyzing adjacent manually entered character information. In this state, the pattern generation control means controls the generation of a character pattern of a desired size corresponding to the manually inputted font character based on the automatically set font size mode, and generates a character pattern of the optimal font size for the manually inputted character information. is possible.

The automatic character size mode processing operation in the character processing apparatus according to the present invention will be described below with reference to FIG.

FIG. 5 is a flowchart illustrating an example of an automatic character size mode processing procedure in the character processing apparatus according to the present invention. Note that (1) to (18) indicate each step.

Wait for the key force from the keyboard KB 1) When the key force is detected, judge whether it is a character code or not 2), N
If O, execute other processing 3) Step (1
).

On the other hand, if the judgment in step (2) is YES, processing is performed according to the currently set font size mode, and if double-width mode is being set, double-width processing is executed.5), and the process returns to step (1). , if half-width mode is being set, execute half-width processing and 6) return to step (1). Note that double-width processing here refers to determining whether the current cursor K is half-width, and if it is half-width, checking the cursor position. For example, if the position is an even number, a space is inserted as a right half-width character, the cursor position is advanced by +1, and double-width processing is executed. This process is a cursor position correction process because normally full-width quintuple-width characters cannot be input from the right half-width position. Next, convert the character code to a double-width character and override the double-width character code at the text buffer position corresponding to the cursor position. Then, the cursor position is advanced by +4, and after table processing, the process returns to waiting for key human power.

On the other hand, in this embodiment, full-width processing involves first correcting the position of the cursor, and then performing full-width character conversion processing. Then, after calculating the position of the text buffer TBUF, the code is overridden, the cursor position is advanced by +2, and after display processing, the process returns to waiting for key input.

Furthermore, in this embodiment, half-width processing does not require cursor position correction processing (after half-width character conversion of input code,
This is a process in which a conversion code is overridden at the position of the text buffer TBUF, the cursor position pointer is advanced by +1, and after display processing, the process returns to waiting for key input.

On the other hand, if full-width mode is set, check if automatic half-width mode is set, i.e. half-width mode key HA
It is determined whether LF is pressed and automatic half-width mode is set. 4) If no, normal full-width processing is executed. 7) The process returns to step (1).

On the other hand, if the judgment in step (4) is YES, it is determined whether the first input character code is a character code corresponding to alphanumeric characters81) If it is No, the half-width processing flag is cleared rOJ9). Execute normal full-width processing (lO) and return to step H.

On the other hand, if the determination in step (8) is YES, it is determined whether the content of the half-width processing flag flag is already "1"11), and if it is YES, the half-width processing is continued 12).
, return to step (1).

On the other hand, in step (11), it is determined whether the character at the current cursor position has a character code corresponding to an alphanumeric character (13). If No, this is the first alphanumeric input, so the half-width processing flag flag is set. "O" clearly 14),
Execute normal full-width processing as shown in Figure 2 (15)
, return to step (1).

On the other hand, if the determination in step (13) is YES, it means that two consecutive alphanumeric characters are present, so a character size correction process in automatic half-width mode is executed (16). Here, the character size correction processing means converting the previous character code, that is, the character code indicated by cursor K shown in FIG. Override the half-width character code converted to . Then, advance the cursor position (cursor pointer) by one half-width size, and convert the input character code to a half-width code at the corresponding position in the text buffer TBUF.
Override.

Then, set the half-width processing flag flag to "1" (
17) Display the contents of the text buffer TBtJF as shown in FIG. 318) and return to step (1).

As a result, for example, if the input character is an alphanumeric character again, the half-width processing flag flag is set to "1", so step (11) branches to half-width processing shown in step (12). . Note that the half-width processing flag f
lag has the role of setting so that half-width processing can be executed directly when three or more alphanumeric characters are input consecutively.

Furthermore, when creating a tabulation document as shown in FIG. 4 with the half-width mode set, it is necessary to change the input portions of the "kanji part" and "four arithmetic operations" to the full-width mode. but,
As explained in the above example, when the automatic half-width mode is set, both the "kanji part" and the "four arithmetic operations" can be input in the current mode, and the numerical part can also be entered as shown in Figure 2. When inputting the head part, full-width input is required,
When two numbers are entered in succession, the previously entered numbers and the currently entered numbers are automatically corrected to half-width characters and a document is created, as shown in FIG.

In this way, there is no need to change the mode at all, and operability can be improved.

In the above embodiment, when setting the full-width input mode, automatic half-width processing is executed when two or more consecutive alphanumeric characters are input. However, when the half-width input mode is set, The present invention can be applied even when automatic full-width processing is executed when character information other than numerical information is input. That is, the process in step (16) above may be omitted and automatic full-width processing may be performed. This will be particularly effective when creating a document, such as inputting a translated Japanese text while creating an English text.

[Advantageous Effects of the Invention 1] As explained above, the present invention includes a mode setting means that automatically sets an optimal font size mode while analyzing adjacent character information that is sequentially input, and a mode setting means that automatically sets the optimum font size mode by this mode setting means. Since the pattern generation control means controls the generation of a character pattern of a desired size corresponding to the input character information based on the character size mode inputted, the input character information is simply forced to be set to one of the character sizes. Compared to the case where character processing is executed based on the mode, the number of mode change key operations is significantly reduced, and the efficiency of inputting character information when creating a document with mixed character sizes can be greatly improved. Therefore, the operator does not have to interrupt the character input process for changing the character size, and the operator can efficiently and continuously input desired character information, which is an excellent effect.
