The characters and symbols typed in are displayed on the large screen display 2.

[Problem to be solved by the invention]

As keyboards become more complex, the line of sight of workers is increasingly on the keyboard.

On the other hand, when converting English characters, hiragana, or katakana typed on a keyboard into kanji, there are many homonyms, so the converted results must be checked, which requires the operator to frequently look at the large screen display. It's here.

However, since the conventional large screen display 2 shown in FIG. 7 is large in size, it stands upright at a position of 30 to 50 cm above the desk, while the keyboard 3 is placed horizontally at a distance of several am above the desk. Therefore, the operator has to change the direction of his/her line of sight by about 45 degrees and move his/her viewpoint by about 50 cm every time the conversion operation is performed, which causes a decrease in the work speed and fatigue of the worker.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a keyboard that can reduce operator fatigue and improve working speed.

[Means to solve the problem]

In order to achieve the above object, the keyboard of the present invention has the following features:
A keyboard 12 that is used separately from the large screen display 11 and electrically connected with the flexible wire 13, and a small screen display 14 that has a function to assist the large screen display 11 on the panel surface 12a of the keyboard 12. It is characterized by being provided with.

[For production]

The keyboard with a small screen display of the present invention is connected to a large screen display with a flexible wire, and alphabetic characters, hiragana, katakana, numbers, or other symbols manually entered on the keyboard 12 and the converted results are transferred to the large screen display 11 and the keyboard. It is displayed on both of the 12 small screen displays 14. Next, when a new alphabetic character, hiragana, katakana, number, or other symbol is entered on the keyboard 12, the large screen display 12 displays the human input data following the previous conversion processing result, but the small The input data is displayed on the screen display 14 after the previous conversion processing results are erased.

〔Example〕

1 to 3 are diagrams showing an embodiment of the present invention, FIG. 1 is a diagram showing the embodiment together with a large screen display, FIG. 2 is a diagram showing a keyboard of the embodiment of the present invention, and FIG. FIG. 3 is a circuit block diagram showing the present embodiment connected to a large screen display.

In FIG. 1, 10 is a device main body, 11 is a large screen display, and 12 is a keyboard of the present invention connected by a flexible wire 13.
As shown in FIG. 2, a small screen display 14 having a function of assisting the large screen display 11 is provided on the panel surface 12a. This small screen display 14
For example, a liquid crystal display device is used, and it is possible to display up to 15 characters in katakana, hiragana, and kanji, and up to 15 or 30 characters in alphabets and numbers. The contents displayed on the small screen display 14 are also displayed on the large screen display at the same time. The contents of the small screen display can be changed by pressing a letter key after pressing the Convert or No Convert key, or by pressing the Cancel key twice in succession, or before pressing the Convert or No Convert key. It is erased by moving the cursor backward using the back key or moving the cursor and overprinting a new character. The same applies not only to hiragana but also to katakana, alphabetic characters, and numbers.

FIG. 3 is a circuit block diagram of this embodiment connected to a large screen display.

In the same figure (a), 16 is a central processing unit (CPU) provided in the main body of the device, 17 is a main memory (main memory), 18 is a keyboard as an input device, 19 is a large screen display as an output device, 20 is a small screen display provided on the keyboard, and these are a control bus 21 for sending control data such as input and output, an address bus 22 for determining which terminal is specified, and a data bus for sending input/output data. It is connected by three buses, 23.

As shown in FIG. 3(b), the main memory 17 has an area (addresses 0 to n) that is written from outside, and an area of memory that is directly involved in input and output (addresses for input/output devices). , an area (indicated by hatching) for a small screen display is provided within this input/output device address.

The operation of this embodiment configured as described above will be explained using FIGS. 4 to 6. FIG. 4 is a flowchart diagram, FIG. 5 is an example of a display displayed on a small screen display, and FIG. 6 is an example of a display displayed on a large screen display.

In Figure 4, when input is entered from the keyboard at ■,
■If the pressed key is a conversion or non-conversion key, or another key (
It is determined whether the key is a to-be-converted key (that is, a key that is scheduled to be converted). ■If it is determined that a character has entered, code 1 is written in the memory, the character is stored in the small screen display address of the main memory, and the process returns to the original state. Repeat this for each character. (Rue) I) This corresponds to, for example, inputting ``gententite'' in hiragana as shown in a-c of FIG. 5, and is displayed on the small screen display. At the same time, another program is always running and displayed on the large screen display, as before.

Next, when the conversion key is pressed at ■, the pressed key is determined to be a conversion key at ■, code 1 is put in the address $, the conversion process is performed by the CPU using a dictionary, and the address for the small screen display in the main memory is saved. Remember and return. (Route ■) This will be displayed on the large screen display and small screen display. This is "as a deduction" shown in Figure 5d.

If this "deduction" character is incorrect, press the conversion key again and it will be converted again according to route ■, and the 5th
``As the original source'' is displayed as shown in Figure e.

If this is correct, type the next character. If this is the key to be converted, the conversion key was previously pressed and code 1 is entered, so go through ■■ in Figure 4 and clear the address for the small screen display in the main memory, and write the code O to the address $. , store the entered characters in the address for the small screen display, return to the previous page, and enter the next character. This corresponds to f1g in FIG. 5, and just before "to" is displayed on the small screen display, the previous "as the original" is erased, and "handling" is newly displayed. On the large screen display, the previous ``As the original source'' is not deleted, and ``Address'' is displayed next to it.

Next, when you press the conversion key, it is converted using route ■, written to the address for the small screen display in the main memory, and then returned. As a result, "Handle" is displayed on the small screen display as shown in Figure 5, and "Handle as original" is displayed on the large screen display as shown in Figure 6.

In this way, the route ■ is a route to be written from the beginning, and the route ■ is a route to be input continuously after a previously converted character.

According to the above-described embodiment, when converting hiragana to kanji, the large screen display 11 is looked at and '61i' is read.
There is no need to recognize the information, and processing can be performed using only the small screen display 14.

〔Effect of the invention〕

As explained above, according to the present invention, the small screen display is provided on the keyboard, so that the operator can move the line of sight between the keyboard and the large screen display for each conversion task. Since there is no need to change the viewpoint, worker fatigue is reduced and work efficiency is improved.
