Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a character input device that is provided with processing functions related to character input in addition to direct character input.

<Prior art> Conventionally, this type of device issues a 411 instruction to cancel the function mode when each function is executed after switching from an input mode for character input to a function mode that performs processing other than character input. In view of the above points, the present invention has been developed in view of the above points. This solves the drawbacks of the conventional technology.

<Problems to be Solved by the Invention> In the conventional character input device, in order to switch to the function mode during the character input mode and return to the execution-execution character input mode of a predetermined function, it is necessary to issue an instruction to cancel the function mode. To solve the disadvantage that an operator must operate during character input by immediately returning to a character input mode after executing a function, or returning to a character input mode by instructing to cancel the function, depending on the nature of the function.

<Means and effects for solving the problems> The present invention provides a character input device that can switch to a function mode in which processing functions other than input can be performed during a character input input mode, from the function mode to the input mode after performing the processing function. When returning to , determine the nature of the processing function and return to input mode immediately after executing the processing function. Furthermore, by continuing the function mode until a function cancellation instruction is given, the operator can save unnecessary operations when returning from the function mode to the input mode and continuing character input while inputting one character.

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

The fi4i diagram is a configuration diagram of an embodiment of the present invention, and in the diagram, l is a keyboard for inputting character symbols, processing instructions, etc.
2 is a central processing unit (hereinafter referred to as CPU), and ROM
(Read-only memory) 3 According to the program 4 shown in FIG. 6 is a RAM (random access memory) that stores character data input from the keyboard 1, and a character memory 7 or C that has an indent position memory that stores the indent position.
It is used as work area 8 of PU2.

In the work area 8 of the CPU 2, there is a remote storage area 9 that stores the state of holding or canceling the input mode or function mode.
It also has a cursor pointer 10 that stores the cursor position. 12 is a display device that displays the contents of the 1-character memory 7,
Display mode status. The situation is shown in Figure 4.

FIG. 2 is a diagram showing a keyboard 1 according to an embodiment of the present invention, where K1 is a group of keys for inputting character symbols.

Fl is the key or 1 to call the indent position setting process
When switched to function mode with the function key F3, the key to call the process of placing the cursor at the beginning of a sentence, F2 is the key to call the hiragana number katakana conversion process, REL is the key to cancel the function mode, F3 is the input mode The key K2 is a group of other keys for switching the mode from to the function mode.

The indent position setting process of the key Fl is a key that directs you to the function mode by pressing the key Fl in the input mode, and returns to the input mode after executing the indent position setting process. ,
After switching to the function mode by pressing the key F3, cursor sentence beginning processing is executed by pressing the key F1,
This key instructs to automatically switch to the input mode after that, and the hiragana/katakana conversion process of the key F2 is executed by pressing the key F2 after pressing the key F3, but the key REL This key instructs to continue the function mode until is pressed.

FIG. 3 is a flowchart showing the contents of the program 4 in the ROM 3, and the CPU 2 performs processing as shown in this flowchart.

The operation of the above configuration will be explained below.

When character input mode is selected, proceed to step S and wait for some key to be input from keyboard 1.
If any key is pressed manually, the process advances to step S2, where it is determined whether the input key is the function key F3, and the key F is pressed.
If it is not 3, the input mode is stored in the mode storage area 9 and the process proceeds to step S3, where it is further determined whether the previously pressed key is the indent position setting key F1, and if the key is F1. Proceed to step S4, execute indent position setting processing for indent position memory 1, and proceed to step s1 after execution; step S
If it is determined in step 3 that a key other than the key Fl is pressed, the process proceeds to step s5, performs the process according to the instructions for that key, and after execution of the process proceeds to step Sl 6. An explanation will be given of the case where the pressed key is key F3. In this case, it is the mode storage area! The function mode is stored in , and displayed as shown in the fourth [ff1(b)]. Then, proceed to step 6 and wait for the first key to be input, and if the key is input, proceed to step S7.
Here, it is determined whether or not the first key input is the key F1. If the key is F1, the process advances to step S8, and cursor sentence beginning processing is executed for the cursor pointer 10. After execution, in step S12, the contents of the mode storage area 9 are set to the input mode and displayed as shown in the fourth [11(α)], and then the process returns to the input mode and proceeds to step S1. Also, in the determination in step S7, if the input key is not Fl, the key to be input manually in the function mode is the hiragana/katakana conversion key F2, so the process proceeds to step 9, where the character code in the character memory 7 is rewritten by the CPU 2, Executes Hiragana/Katakana conversion processing. Then step S
Go to Step 10, have the key input first, and if the key is pressed, go to Step Sll, Step S
In ll, it is determined whether the input key is the function mode release key REL, and if it is not the key REL, the function mode is maintained with the contents of the mode storage area set to the function mode,
Proceed to step S6, and if the key input in step Sll is the key REL, step S5
Proceeding to step 12, the contents of the mode storage area 9 are set to input mode, the function mode is canceled, the process is switched to input mode, and the process proceeds to step St.

In other words, for processing that only needs to be performed once, such as indent position setting processing and cursor start processing, by returning to the input mode after the processing is executed, characters can be input without any operations after the processing is executed. Also, when converting character data in the character memory 7, such as hiragana/katakana conversion, by converting human-generated characters one by one, it is often necessary to convert multiple characters in succession like a word, so the key R
The functional mode shall be maintained until EL is input. In this case, after converting the desired characters, press the key RE.
Returning to input mode by inputting L After switching to function mode during input mode and executing each process, the method of returning to character input mode is changed depending on the nature of the process, as in 0 or more, where inputting L returns to input mode. This makes it possible to continue inputting characters after processing without requiring any extra operations.

In this embodiment, an indentation position setting function, a hiragana/katakana conversion function, and a cursor movement function are taken as examples, but the function content is not limited to these, and the nature of the function may be such that it can be executed in one click. It can be applied by classifying it into those that are used continuously and those that are used multiple times in a row.

<Effects of the Invention> It is possible to switch to a functional mode in which processing other than character input is performed during the input mode for character input according to the present invention, perform the above-mentioned processing, and input from the functional mode in order to continue inputting characters without performing processing. When switching to the input mode, the operator can use a character input device that can automatically switch to the input mode after execution of the process depending on the nature of the process executed, or can maintain the function mode until an instruction is given to cancel the 1 function mode. Even if the user temporarily calls up the function mode and performs a processing operation while inputting characters, it is possible to continue inputting characters without having to perform unnecessary operations such as canceling the machine mode each time after completing the processing operation. Become. This eliminates the troublesome operation for the operator, and makes it possible to reduce the number of operations and input time.
