Abstract

PURPOSE:To make a mode conversion key unnecessary for the user, by constituting to determine a key mode in accordance with an instruction of an internal program. CONSTITUTION:A display device 2, a keyboard 3, an ROM4, and an RAM4 are connected to a CPU1. Display patterns corresponding to four key modes, namely, an alphabet mode, a Kana (Japanese syllabary) mode, a numeric mode, and a graphic mode are divided to four areas and are stored in address spaces ROM A-ROMD of the ROMs 4. Instructions for conversion to respective key modes are set in the program. Since the key mode is switched to various key modes automatically by these instructions, it is unnecessary that the user depress the conversion key each time, and an operator can use the keyboard to input data without paying attention to key mode conversion.

Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to electronic equipment, and more particularly to an electronic equipment equipped with a keyboard capable of processing information and capable of performing various key operations manually.

BACKGROUND OF THE INVENTION Due to advances in LSI, this type of electronic equipment has become equipped with a large number of functions even though it is small.

For this reason, there are many different types of operations, and the number of types of keys is increasing.

For example, in conventional personal computers, etc., kana keys, alphabet keys, graphic keys, numeric keys, etc. are located on the same key, and one key functions as multiple types of keys.

In this way, one key must perform the various functions described above, and the user selects the mode to be used by using keys such as the shift key, kana mode key, and graphic mode key.

Therefore, if such a method is adopted, a plurality of types of mode conversion keys are required in addition to the normally required keys.

Otherwise, conversion cannot be performed, and these electronic devices cannot be operated unless one is familiar with the meaning of the mode conversion key.

Purpose The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology, and by configuring the key mode to be determined by instructions in an internal program, the user's operation of the mode conversion key can be improved. The purpose is to provide electronic devices that are no longer needed.

EXAMPLES Hereinafter, the present invention will be explained in detail based on examples shown in the drawings.

FIG. 1 is a block diagram illustrating the basic principle of the present invention. In the figure, reference numeral 1 indicates a central processing unit (CPL 7), and this CPU 1 includes a display device 2, a keyboard 3, and a fixed storage device (ROM) 4. and random access memory (RAM) 5 are connected.

The ROM 4, which is a fixed storage device, stores display patterns for displaying key presses. That is, for example, if an electronic device to which the present invention is applied has four key modes, in other words, an alphabet mode, a kana mode, a numeric mode, and a graphic mode, the keys corresponding to the keys of each mode The display pattern to be displayed is divided into four areas and stored in the address spaces of ROMAXROMB, ROMC, and ROMD in ROM4, respectively.

Based on the structure described above, in the present invention, instructions (commands) for converting to each key mode are set in the program.

That is, in the present invention, the command 0 (MC) is used to switch KMC, 1 to alphabet mode, I (MC2 to kana mode, KMC3 to numeric mode, and KMC4 to graphic mode. .

Next, regarding the operation of this embodiment configured as above,
This will be explained using the program chart shown in FIG. 2 and the flow chart shown in FIG.

The program chart shown in FIG. 2 is an example of a test score processing program, and the electronic device to which the present invention is applied is automatically set to alphabet mode in the initial state. be.

First, when the score processing program is started by a manual instruction, the device that has been in the alphabet mode changes to the katakana mode by executing the command KMC2 in step S1. The user is informed by the display device 2 that the Konogana mode has been entered, and if, for example, “Jinmei Filleyo” is displayed on the display device 2, the user inputs the name of the person using the alphabetic keys in step s3. do. The result of this manual input is shown on the display device 2.

Subsequently, the program executes the code r in step s3.
Execute all commands KMC3. By executing this command KMC3, the electronic device side is converted to numeric mode.

This number mode is also displayed by the face thread device 2, and the user inputs the score of the test result using the alphabetic keys. The input results are of course displayed on the display device 2 (step S, ).

The program then proceeds to step S, where it calculates the total score and average score for each subject input in each step, and performs a process of displaying and outputting the results.

If the grade processing program ends here, the command KMC1 is executed in step S6, the device is switched to the alphabet mode which is the initial setting state, and the program ends.

In this way, since the commands in the program automatically switch to various key modes, the user does not have to press the conversion key one after another, and can switch between key modes one after another without being aware of the key mode conversion. You can input using the keyboard.

FIG. 3(A) shows a processing routine within the CPU when the commands KMC1 to KMC4 are executed on a program.

In FIG. 3, it is first determined in step A whether or not the command is KMC1. If it is determined that the key is KMC1, since the mode is alphabetic, the process proceeds to step A2, where a character similar to the pressed key is extracted from the ROMA address of the fixed storage device 4.

If the command is not KMC1, the process advances to step A3 and it is determined whether the command is KMC2. If the command is KMC2, since the mode is Kana mode, the process proceeds to step ^, where the character corresponding to the pressed key is extracted from the ROMB address.

If the command is not KMC2, step A;
It is determined whether the command is KMC3 or not.

If the command is KMC3, since the mode is number mode, the number corresponding to the pressed key is extracted from the address in the ROMC (step Aa).

If the command is not KMC3, the process advances to step A7. In this case, since the command is not one of the commands KMC1 to KMC3, the command is KMC4, and the pattern corresponding to the graphic mode is found from the ROMD address. selected.

On the other hand, FIG. 3(B) shows the processing routine within the CPU when the key is input manually.

In FIG. 3(B), first, in step B, it is determined whether or not there is key human power. If there is no key manpower, this loop is repeated.

If the key is available, the process proceeds to step B2, where the address (7) of the corresponding display pattern for that key is determined from the set address in the fixed storage device 4 and the key code itself, and the process proceeds to step B3, where the pattern information is stored. It can be extracted and displayed, or used as processing code inside the CPU.

Effects As is clear from the above explanation, the present invention employs a configuration in which the key mode is determined by a command during the program, so that the programmer can set the key mode in advance according to the user's key usage status. The user can use the keyboard without knowledge of keyboard mode conversion, and there is no need for multiple mode conversion keys.
