Abstract

PURPOSE:To enable the subsequent users to perform quick operations by displaying the setting enable character space as well as a fact that the setting is impossible with an input character space. CONSTITUTION:A character space setting program 31 is stored in a program memory 30. A central processing unit 20 decides under the control of the program 31 whether the character space supplied from a keyboard 10 can be set or not. If the input character space can be set, the unit 20 sets the character space of the document data stored in a document memory area 41 based on the due value. While the setting enable space is displayed on a display device 50 together with a fact that the setting is impossible with said input character space. Thus the setting operability is extremely improved for the character space.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for setting character spacing in dot units, etc. in a document creation device. Regarding the processing method.

[Background of the invention]

In a document creation device, if character spacing can be set in units of dots, it becomes possible to create documents in any format. However, while there is no problem when narrowing the spacing between characters, when widening the spacing between characters, there is a limit depending on the number of dots allocated to one line and the number of characters included in one line, and the character spacing cannot be increased indefinitely. In this way, if the character spacing entered by the user cannot be set, instead of simply displaying an error message or sounding a buzzer, if the user could know the maximum character spacing that can be set, they would be able to take immediate action. It's convenient.

[Purpose of the invention]

The purpose of the present invention is to set the character spacing in dot units or the like in a document creation device, and when it is impossible to set the character spacing,
The purpose is to improve operability by notifying the user of character spacing that can be set under given conditions.

[Summary of the invention]

The present invention is a document creation device equipped with a single-character spacing setting function, and when the input character spacing cannot be set, the character spacing that can be set is displayed and the character spacing that can be set is displayed. This allows users to take prompt action.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of an implementation of a document creation device to which the present invention is applied. This document creation device includes a keyboard 10 for inputting single characters and various operation instructions, a central processing unit 20 for executing document creation and other processing, and a program memory (for storing programs necessary for processing in the central processing unit d20).
ROM) 30, a data memory (RAM) 40 for storing document data or various files, and a display device 50 for displaying documents and other screens. There is a document memory area 41 on the data memory 40, into which created document data is stored.

Now, on the program memory 3o, there is a character spacing setting program 31 as a program related to the present invention. Under the control of the character spacing setting program 31, the central processing unit 20 determines whether the character spacing input from the keyboard 10 can be set, and if it is settable, the characters of the document data in the document memory area 41 are adjusted according to the value. The spacing is set, but if it is not possible to set it, a process is executed to display that fact and the settable character spacing on the display device 50.

FIG. 2 shows a flowchart of character spacing setting processing according to the present invention. First, when setting the character spacing,
0 to display the character spacing setting screen (step 101),
Obtain key power from the keyboard 10 (step 102)
Step 1: Determine the human power of this key (Step 103), and sound the buzzer as an error because the keys other than the numeric keys and execution keys are not powered by the key required to set the character spacing (Step 1)
04), Return to key manual state. In the case of number keys, the entered number is displayed on the screen (step 105), and the key is returned to the manual state. By repeating steps 102→1°3→105, the character spacing is input.

Next, when the execution key is pressed, the maximum settable character spacing is calculated (step 106). This settable maximum character spacing X is determined by the following formula.

Next, the input character spacing is compared with the maximum settable character spacing X, and it is determined whether the input character spacing can be set (step 107). Set the character spacing of the document data according to the spacing value (step 108), and if the setting is impossible, display the maximum settable character spacing X on the screen along with an error message (step 109) return.

〔Effect of the invention〕

As is clear from the above description, according to the present invention.

When setting character spacing in units of dots, etc. on a document creation device, what happens if the character spacing becomes impossible to set?

Since the user is informed of the character spacing that cannot be set and the character spacing that can be set, the operability of setting the character spacing is significantly improved.
