Abstract

PURPOSE:To reduce the burden of an operator by providing a means to execute a processing to return to a standard processing mode immediately when a specified key is operated again on detecting that the other key is operated following the operation of the specified key. CONSTITUTION:When a specified key 11 of a keyboard 3 is pressed, an executing means 10 switches a processing mode with judging that it is changed from the designation of a standard character to the designation of a half size character based on the indication of an indicating program 12 when the specified key 11 is the same function as a reduction mode key, for instance. Then, next, when a key to designate the other character code of the keyboard 3 which is different from the specified key 11 is pressed, a corresponding half size character pattern is read from a character generating circuit 4 and is developed to a memory 5, and it is stored that the pressing of the specified key 11 is interrupted by the pressing of the other key. Here, next, when the specified key is pressed, it returns to a standard processing mode according to the fact that the pressing of the specified key 11 is interrupted by the pressing of the other key. Thus, the burden of an operator can be reduced.

Description

[Detailed Description of the Invention] [Summary] This invention relates to a specific key that can specify a plurality of different processing modes for a data processing device by repeating key operations, and is particularly effective in effectively switching between the processing modes. The purpose of this method is to improve key operability and reduce the burden on the operator.The system is designed to improve key operability and reduce the burden on the operator. In a data processing device that is equipped with a function to sequentially switch to a plurality of different processing modes and return to the standard processing mode, when it is detected that another key has been operated following the operation of a specific key, The present invention is configured by providing means for immediately returning to the standard processing mode when the key is operated again.

[Industrial application field]

The present invention relates to a specific key that can specify a plurality of different processing modes for a data processing device by repeating key operations, and in particular, processing mode switching using a specific key that can effectively switch the processing mode. Regarding the method.

In interactive data processing devices such as Japanese word processors, switching between various processing modes is realized by key operations on the keyboard, but there is a limit to the number of keys that can be placed on the keyboard, and the data processing device As the functions of computers become more abundant, there is an increasing need to be able to specify multiple processing modes by operating a single key.

When specifying multiple processing modes with different contents using a single key operation, normally each press of a key instructs the data processing device to switch processing modes in a predetermined order. , the processing mode is switched sequentially, and the desired processing mode can be specified in accordance with the number of key presses.

By the way, generally when a data processing device is performing processing in a standard processing mode, a specific key provided on the keyboard is pressed to specify the desired processing mode, and processing in the specified processing mode is completed. The next step is often to return to the standard processing mode, but the specific key operations at this time need to be simple.

(Prior Art) In Japanese word processors, each time a specific key as mentioned above is pressed once, multiple processing modes are sequentially switched in a predetermined order.For example, the standard character size is reduced to 1/2. The reduction mode key for specifying a half-width character reduced to the width, a superscript to be subscripted to the top of a standard character, and a subscript to be subscripted to the bottom of the standard character will be explained.

When this reduction mode key is pressed once while creating a document or the like using standard size characters, a processing mode using half-width characters is first specified, and standard size characters rAJ are reduced to rAJ. If you press it once again, the processing mode will be set to use superscripts, and the standard size characters will be set to "0".
It is reduced as follows. Subsequently, pressing the button once more specifies a processing mode that uses subscript characters, and the standard size characters are reduced to look like "ka". Then, if you press it once more, the processing mode that uses standard size characters is specified,
Return to original state.

[Problem to be solved by the invention]

In a Japanese word processor, when operating a specific key for instructing switching of processing modes, such as the reduction mode key, the frequency of use for each processing mode is not equal.

For example, the frequency of use of superscripts and subscripts is extremely low compared to the frequency of use of half-width characters.

However, conventionally, when switching from standard characters to half-width characters, manually inputting the half-width characters, and then returning to standard characters, it is not possible to immediately return to standard characters. That is, a superscript character is specified, a subscript character is specified, and then a standard character is specified. That is, each time the reduction mode key is pressed, the processing mode switches from standard to half-width, superscript, subscript, and standard, so it is not possible to simplify key operations such as standard, half-width, and standard.

In this way, when specifying multiple processing modes with one key operation, the processing modes change in a predetermined order according to the number of key presses, making the key operation cumbersome and
If the wrong number of key presses is made, it is necessary to press the key again, resulting in poor operability (and a heavy burden on the operator).

In view of these problems, the present invention switches from the standard processing mode to the specified processing mode by pressing a specific key, and after the pressing of the specific key is interrupted by pressing another key, the next When the specific key is pressed, the purpose is to directly return to the standard processing mode, thereby improving key operability and reducing the burden on the operator.

[Means to solve the problem]

The present invention is an improvement that takes into account the frequency of use of the processing mode specified by a specific key and allows the processing mode switching instruction to be given as follows.

That is, for example, with the reduction mode key as described above, (1) If the reduction mode key is pressed repeatedly, the processing mode will be switched from standard to half-width one, superscript one, subscript one, standard one, as in the past. It is repeated sequentially like half-width one, superscript, one subscript, one standard.

2) If the reduction mode key is pressed again after pressing the reduction mode key is interrupted by pressing another key, the process returns directly to the standard processing mode. For example, when the reduction mode key is pressed once, the processing mode is switched from standard to half-width,
If another key is pressed here and a half-width character is input, then when the reduction mode key is pressed again, the mode immediately returns to normal and the switching to superscript and subscript processing mode is skipped.

FIG. 1 is a block diagram of the principle of the present invention.

The execution means 1O reads the program from the disk 9 via the disk control circuit 8, stores it in the memory 5, and operates according to instructions from this program. At this time, instruction program 12
are also stored at the same time. The execution means 10 stores the character code input from the keyboard 3 in the memory 5 and then reads it out. When the corresponding character pattern is read out from the character generation circuit 4, it expands one line in the memory 5, and stores the expanded one line of characters. The pattern is scanned and read out, and sent to the display section 7 via the display control circuit 6 for display.

When the specific key 11 of the keyboard 3 is pressed, the execution means 10 executes the function based on the instruction from the instruction program 12. For example, if this specific key 11 has the same function as the reduction mode key, the execution means 10 converts the specification of standard characters to half-width characters. It is determined that the specification has been changed to , and the processing mode is switched. Then, when a key specifying another character code on the keyboard 3 different from the specific key 11 is pressed, the corresponding half-width character pattern is read from the character generation circuit 4 and developed in the memory 5, and the specific key 11 is pressed. remembers that the press of the key was interrupted by the press of another key.

Here, when the specific key 11 is pressed next, the specific key 1
Since pressing 1 was interrupted by pressing another key, the standard processing mode is immediately returned, and the next character code input from the keyboard 3 is developed in the memory 5 as a standard character.

[Effect]

With the above configuration, when the execution means 10 detects that another key is pressed after the specific key 11 is pressed, the execution means 10 immediately changes the processing mode to the standard processing mode according to the instruction of the instruction program 12. To return, press specific key 11
Compared to the case where the key cannot be returned to the standard processing mode unless the key is pressed multiple times, the operability of the key is improved and the burden on the operator can be reduced.

〔Example〕

FIG. 2 is a block diagram of a circuit showing an embodiment of the present invention.
FIG. 3 is a flowchart illustrating the operation of FIG. 2.

The processor 1 reads an initial setting program stored in the ROM 2 to start operation, reads the program from the disk 9 via the disk control circuit 8, and stores the program in the memory 5.
It is stored and read out, and operates according to the instructions of this program. At this time, the instruction program 12 is also read out and stored in the memory 5.

As shown in FIG. 3, the processor 1 monitors the input from the keyboard 3, and when the end key is pressed, the process is terminated. However, if the end key is not pressed, a specific input is made as shown in FIG. Check whether key 11 is pressed, and check if key 11 is pressed.
If the key is not pressed, the process corresponding to the pressed key is performed.

That is, for example, when a character code is input from the keyboard 3, this character code is stored in the memory 5 and then read out, and when a corresponding character pattern is read out from the character generation circuit 4, it is developed in the memory 5 and then read out. , and is sent to the display section 7 via the display control circuit 6 for display.

Then, when the information on the pressed keys is stored in an internal register or the like for the next comparison, the input monitoring routine from the keyboard 3 is almost returned.

In FIG. 3 (■), when the specific key 11 is pressed, the processor 1, based on the instructions from the instruction program 12, uses the information of the pressed key stored for comparison to determine the previous pressed key, as shown in FIG. 3 (■). It is checked whether the key pressed was also the specific key 11.

If the most recently pressed key is not the specific key 1, the next processing mode is determined based on the processing mode currently being executed. That is, for example, if the processing mode currently being processed is a standard processing mode that uses standard characters, the process switches to a half-width processing mode that uses half-width characters based on a predetermined order, and then switches to this half-width processing mode. remember things.

If the processing mode currently being processed is other than the standard processing mode, it is switched to the standard processing mode. After the information on the pressed keys is saved for the next comparison in the same manner as described above, the process returns to the input monitoring routine from the keyboard 3.

In Figure 3■, the key pressed immediately before is the specific key 1.
If it is 1, the processing mode is switched to the next processing mode of the currently designated processing mode based on a predetermined order. That is, the next superposition processing mode is set based on the half-width processing mode being stored, and this is stored. After saving the pressed key information for the next comparison, the process returns to the input monitoring routine from the keyboard 3.

Here, when the specific key 11 is pressed repeatedly, the standard -
A description will be given of how the processing mode changes by key operation when the processing mode changes from half-width, superscript, subscript, standard.

BCD = Pressing specific key 11 - Standard That is, when the current processing mode is standard, pressing the specific key 11 once will switch to half-width processing mode, and then key to specify characters When inputting ABCD manually, half-width characters ABCD is written,
The next press of the specific key 11 indicates that the standard processing mode is returned to and the superscript processing mode and subscript processing mode are skipped.

(2) When using superscript processing mode Standard - Press specific key 11 - Half-width - Press specific key 11 - Superscript - 4 - Manual ABc D, AB e I) - Press specific key 11 - Standard In this case, When the current standard processing mode is pressed, pressing the specific key 11 twice will switch to superscript processing mode. Next, when ABCD is entered manually using the key to specify a character, superscript characters A8eD will be written, and the next specific Pressing the key 11 returns to the standard processing mode, indicating that the subscript processing mode has been skipped.

(3) When using subscript processing mode Standard - Press specific key 11 - Half-width - Press specific key 11 - Superscript → Press specific key 11 → Key manual ABCD - AIl:D
- Pressing the specific key 11 - This is the standard (in the case of 11, the number of operations of the specific key 11 is only two times, which improves the operability compared to the conventional four times).

〔Effect of the invention〕

As described above, the present invention can improve key operability and reduce the burden on the operator when specifying a plurality of processing modes with a single key operation in an interactive data processing device.
