Abstract

PURPOSE:To correct information inputted by a simple job requiring a short time, by arranging overlappingly a transparent keyboard on a display screen of a display device and correcting a desired correcting part through the depression of the transparent keyboard. CONSTITUTION:A CRT1 displays characters of, e.g. 80 lines X 4 stages and the transparent keyboard 2 (80X4 keys) having a matrix corresponding to this display is connected to a CPU3. Further, the information inputted from the keyboard 4 is displayed on the CRT1 and when the input information is desired to be corrected, the keyboard 2 overlapped with the CRT1 to designate the head part of the corrected part in succession to the depression of a correcting mode designating key for deletion or insertion. Then, when the correcting mode designation is ''deletion'', a traced part is deleted by moving a finger or a rod placed on the keyboard 2 by the operator. When the correcting mode is ''insertion'', spaces for the traced number are inserted into a part started for tracing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device, and particularly to an electronic device that has an input device and an input information display device, and has a function of correcting input information.

Conventionally, as a method for processing information in computers, word processors, etc., the system is equipped with an input device such as a keyboard, and a display device such as a CRT, and when you want to correct information that has been input, you can use the cursor provided on the keyboard. CR using movement keys etc.
It was common practice to move the cursor on the T screen to the desired correction location and then use the insert key, delete key, etc., or to correct the input information by overwriting.

Entering information using a keyboard is easy to get used to since it is often done using English typewriters, but ordinary typewriters are not equipped with the cursor movement keys, erase keys, insert keys, etc. mentioned above. It is extremely difficult to operate these keys without taking your eyes off the screen, and it takes time to make corrections or learn how to do so.

In particular, with the spread of personal computers, word processors, etc. in recent years, people other than specially trained operators are increasingly exposed to these devices.
There is a growing demand for an electronic device that has a correction function that can be performed more easily and quickly and that does not require time to learn the work.The present invention was made in view of the above points, and the present invention has been made in view of the above points. The purpose is to provide an electronic device with a correction function that is easy to learn.

In order to achieve the above object, an electronic device having a central processing unit for processing information, a means for storing the information, a display device for displaying the information, and an input means for inputting at least a processing mode, A transparent keyboard having keys at positions corresponding one-to-one to display positions of the display device is arranged over the display screen of the display device, and a desired correction part in the information being displayed can be changed using the transparent keyboard. By pressing , a modification mode such as deletion or insertion is designated by the input means to modify the information.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. However, in the following explanation, a computer system will be used as an example.

FIG. 1 shows the basic configuration of an electronic device according to the present invention.
T, the reference numeral 5 is a RAM (random access memory), the reference numeral 4 is, for example, an English typewriter type keyboard, and these are connected to a CPU (central processing unit) 3+. The above configuration is a commonly known computer system, in which information input from the keyboard 4 is stored in the RAM 5, and the CRTI
It can be displayed and various types of processing can be performed. It is also assumed that the keyboard 4 has keys for specifying modification modes such as deletion and insertion. This designation key is also known.

The CRTI of this embodiment is capable of displaying, for example, 80 digits x 4 columns of characters, and furthermore, in the electronic device of the present invention, the 80 digits
A transparent keyboard 2, also having an 80×4 matrix corresponding to a ×4 display, is connected to the CPU 3. This transparent keyboard 2 is a publicly known one, and has approximately the same size as the screen of the CRTl, and is placed overlapping the screen side of the CRTI, allowing the operator to view the screen of the CRTI through its transparent keys. It is possible.

In the present invention, the information input from the keyboard 4) is displayed on the CRTI, and if the input information is to be corrected, the erase mode designation key such as the erase or insert button on the keyboard 4 is used. Transparent keyboard 2 with one layer lowered and erase mode specified, and four CRTs stacked one on top of the other.
Press the key corresponding to the number of the desired first conquest (in other words, as an operator, you can move your finger on the screen,
1t± Push or trace with a stick, etc. ) Specify the parts to be corrected and make the corrections.

CRTI and transparent keyboard 4 joushi 80 as mentioned above
It has 4 display positions, and 1, 2, 3...
..., and the lower right blade is 320. At this time, the key code ``4'' on the right side of the screen becomes a large number and becomes 1/). MiJδ's own keyboard'
The key code of the modification mode designation key in 4'2 is expressed as ``1'', and the key code of the key pressed on the transparent keyboard is expressed as ``2''.

Hereinafter, the subroutine of the correction operation performed by the CPU 3 in the above configuration will be explained with reference to the flowchart shown in FIG. This subroutine is entered by pressing the deletion or insertion modification mode designation key.

First, in step 1 of FIG. 2, after pressing the deletion or insertion correction mode designation key (key code t±Kl), the transparent keyboard 2 arranged on the CRT l l is pressed (this key code 1iK2). Wait for the beginning part of the correction part to be specified. Continuing to step 1/X, in step 2, 2 is set as column (hereinafter referred to as COL) 1, and in step 3, the CPU 3 starts a built-in timer.

Next, in step 4, the operator moves a finger or stick placed on the transparent keyboard z to determine whether or not the next key has been pressed. If pressed, move to step 5 and set 2 to C0L2.
After that, reset the timer and return to step 3.

That is, if the operator continues tracing on the transparent keyboard 2, steps 3 to 5 will be repeated to move the code of C0L2.

When the operator finishes tracing the desired correction location, 2 is not input in the next new field in step 4, so the process moves to step 6, checks the time measured by the timer started in step 3, and determines whether t seconds have elapsed. do. In other words, it is checked whether the operator has completely stopped tracing the finger on the transparent keyboard.This t second is set to about 0.3 to 0.5 seconds, but it can be changed depending on the usage situation of the operator. If you confirm that the operator has completely stopped his finger in step 6, move to step 7 and check the key code of the correction mode designation key for 1 when entering the correction subroutine. Determine whether the type is an erase key or an insert key.

If it is determined in step 7 that the correction mode designation key is an erase key, the process moves to step 8, and the C0LI
Then, in step 9, move the information after CC) L2 to the position of COL 1 to fill up the space6.However, skip this step 9 and leave the erased space as it is. Of course it's good too.

On the other hand, if it is determined in step 7 that the specified key is an insert key, the process moves to step 10, and COL 1
The number of spaces from COL2 to COL2 is inserted immediately after COL1, and then in step 11 the cursor is moved to the beginning of the inserted space. However, the character string to be inserted into this space may be stored in advance in a predetermined buffer memory, and the stored character string may be added in step 11.

To summarize the above operations, when performing a correction operation, the operator first specifies the mode by pressing the erase key or insert key on the keyboard 4, and then presses the CR
If you trace an undesired part on the TI with your finger or a stick through the transparent keyboard 4, that part will be erased, and in the case of insertion, spaces will be inserted at the point where you started tracing as many spaces as you traced. It turns out.

Since the operations of deletion and insertion mentioned above are well known, they will not be explained in detail here.

The correction operation according to the present invention is similar to the operation of erasing characters on paper with an eraser in the case of erasing, and the operation of expanding the space between characters with a finger in the case of insertion, and is generally used in electronic devices. It can be easily performed even by people who are not familiar with it, and corrections can be made without any discomfort using intuitive and natural operations, and communication between humans and electronic devices such as computers or word processors has become much easier than before. It can be made smoother.

The above configuration can be applied to any electronic device that has a central processing unit combined with a display device and a storage device and can input or modify stored information. Of course.

As is clear from the above description, according to the present invention, there is provided a central processing unit that processes information, a means for storing the information, a display device that displays the information, and an input that allows inputting a processing mode without walking. In an electronic device having means,
A transparent keyboard device having keys at positions corresponding one-to-one to the display positions of the display device is placed over the display screen of the display device, and a desired correction location in the information being displayed can be edited using the transparent keyboard device. The system employs a configuration in which information is corrected by manually specifying a correction mode such as deletion or insertion by pressing the keyboard, so input information can be corrected easily and in a short time. It is possible to provide an electronic device with a correction function that allows easy learning of correction work.
