Abstract

PURPOSE:To display the input data before the internal processing of an electronic computer is carried out and to improve the input job efficiency by storing the coded input data inputted with a key operation into a display-only buffer and then displaying those stored data after converting them into the output data. CONSTITUTION:A data code generating part 2 generates a corresponding code and stores this code in a buffer 3 with push of an input key 1. Then the code is fetched by an electronic computer 21 from the buffer 3 and processed by a control part 5. The processed code is outputted to a display 7 and a printer 8. When a display device control part 10 judges that an input code is not returned, the input code is stored in a buffer 9 and converted into the output data with an output instruction of the part 10. Then the output data are displayed by a display device 11. Meanwhile the buffer 9 is erased and the device 11 is cleared if the input code is returned. As a result, the input data can be confirmed in real time and the key input job efficiency is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a keyboard device used as an input device for a computer or the like.

[Prior Art] A conventional keyboard device of this type is shown in FIG. FIG. 3 is a block diagram showing the configuration of a keyboard device connected to a computer, where (20a) is the keyboard device and (21) is the computer.

In addition, in the keyboard device (20a'), (1) is an input 'r-1, (2) is a data code generation unit that encodes key-input data, and (3) temporarily stores encoded input data. (4) indicates a control signal transmitter that notifies the electronic computer (21) that a key input has been made.

In the electronic computer (21), (5) is a CPU control unit, (6) is a memory, (7) is a CRT display,
(8) indicates a printer.

Next, the operation will be explained. When the input key (1) is pressed, the data code generator (2) generates the corresponding key (1).
) is generated, and the generated 1
The hexadecimal code is stored in the buffer (3), and the input of the data is detected by the control signal generator (4).
The CPU control unit (5) is notified, and the CPU that received this notification
The control unit (5) imports the hexadecimal code stored in the buffer (3) into the electronic computer (21) side, and stores it in the memory (6).
Store in. That is, until the generated code is imported into the computer (21), the hexadecimal code is stored in the buffer (3) within the keyboard device (20a).

And the hexadecimal code stored in memory (6) is C
According to an output command from the PU control unit (5), the data is converted into output data (characters) and sent to a CRT display (7) or printer (8) for data output.

[Problems to be Solved by the Invention] Since the conventional keyboard device described above is configured as described above, it is difficult to avoid a problem in which a large load is placed on the computer due to, for example, the computer performing other processing. If this happens, the processing speed of the CPU control unit will decrease, it will take a long time from key input to output to the display, and input data will not be checked immediately.

Additionally, if it is necessary to pre-enter the next input while a job is being executed, the pre-entered data will be mixed in and displayed in the job being executed, causing problems such as difficulty in checking the input data. there were.

The present invention has been made to solve this problem, and its object is to provide a keyboard device that allows input data to be checked in real time regardless of the operating status of a computer.

[Means for Solving the Problems] A keyboard device according to the present invention includes a display-only buffer for storing coded input data entered by keys, and an input data code stored in the display-only buffer as output data. A display device for converting and displaying images and a control unit therefor are built into the device.

[Function] The keyboard device of the present invention includes a display-only buffer that stores key-input and coded input data, and a display that converts the input data code stored in the display-only buffer into output data and displays it. Since the device and its control section are built into the device, input data can be displayed without waiting for processing within the computer.

[Example] An example of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention, in which the same reference numerals as in FIG. 3 indicate the same or corresponding parts;
9) is a display-only buffer provided separately from the buffer (3), (10) is a display device control section, and (11) is a display device provided within the keyboard device, which is composed of, for example, an LCD. (20) is a keyboard device in this embodiment.

FIG. 2 is a flowchart for explaining the operation of this embodiment, and in the figure, (S1) to (S8) indicate each step, respectively.

Next, the operation will be explained. When the input key (1) is pressed in step (Sl), the data code generation section (2) generates a hexadecimal code corresponding to the key (1) in step (S2), and the generated 16 The decimal code is stored in the buffer (3). The hexadecimal code accumulated in the buffer (3) is taken into the electronic computer (21) side in the same way as in conventional devices, and is sent to the CPU control unit (5).
) and then output to a CRT display (7) or printer (8).

On the other hand, in this embodiment, in step (s3), the coat input by the display device control section (10) is
If it is not a Return code, the input code is stored in the buffer (9) in step (S4), and in step (s5) it is determined by an output command from the display device control unit (10). It is converted into appearance data (characters) and displayed on the display device (11).

Note that if the input code is a deletion code, the code most recently stored in the buffer (9) is deleted.

On the other hand, if the input code is a return code, the process moves to step (S6) and the contents of the buffer (9) are erased, and the display device (11) is cleared in step (S7). Such operations are repeated until the power is turned off in step (S8).

In this embodiment, as described above, the input data is not sent to the computer (21), but the input data is sent to the keyboard device (21).
) so that it is processed and displayed in a computer (
21) It becomes possible to check input data in real time regardless of the operating status.

In the above embodiment, the contents accumulated in the buffer (9) are updated for each Return code, but the fourth
As shown in the figure, a memory (40) is provided in the keyboard device, the contents of the buffer (9) are sequentially stored in the memory (40), the contents of the memory (40) are sequentially selected from new inputs, and the contents of the memory (40) are sequentially selected from new inputs. (3) and the function of restoring data to the buffer (9) makes it possible to improve the efficiency of re-inputting previously input data.

[Effects of the Invention] As explained above, this invention allows input data to be displayed without waiting for processing within the computer, so input data can be checked in real time regardless of the operating status of the computer. Input data can be checked instantly even on computers with slow processing speeds or computers that are executing jobs.
This has the effect of making correction work easier and improving the efficiency of key input work.
