Abstract

(57) [Summary] [Objective] To provide a keyboard device that allows visually confirming the contents of a buffer memory that have been previously input. [Structure] A display device 10 displays data stored in a buffer memory 8. Therefore, if data has been retained in the buffer memory 8 for a certain period of time or more, you can visually confirm the contents, and if you wish to make corrections, erase the contents of the buffer memory 8 by operating the cancel key, and then operate the key 6 again. Just enter it.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a keyboard device as an input device for personal computers, etc. It is something that

0002

[Conventional technology]

Traditionally, keys have been used as input devices for personal computers, workstations, etc. - The board device is in a state where the computer's CPU does not accept input data. It also has a built-in buffer memory so that a certain amount of data can be input ahead of time. ing.

0003

[Problem that the idea aims to solve]

However, conventional keyboard devices cannot store data stored in buffer memory. It was difficult to correct the data because it was not possible to confirm the data. The present invention was developed in view of the above circumstances, and it is possible to use the pre-input buffer memory. The purpose is to provide a keyboard device that allows visually confirming the contents of the memory. .

0004

[Means to solve the problem]

This invention is equipped with a buffer memory that temporarily stores data input by keys. displaying data stored in the buffer memory in the keyboard device A display device is provided to display the data and also to cancel the data by pressing the cancel key. It is characterized by a structure in which the contents of the file memory can be erased.

[0005]

[Effect]

The display device displays data stored in the buffer memory. Therefore, de If data has been held in buffer memory for more than a certain amount of time, its contents can be visually displayed. If you can confirm and want to make corrections, use the Cancel key to erase the contents of the buffer memory. After deleting it, enter it again.

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings. Figure 1 shows a personal computer equipped with a keyboard device according to an embodiment of the present invention. This is a configuration diagram of the main parts of the computer.The computer body 1 includes a CPU 2 and serial input/output An interface 3 and the like are provided. The keyboard device 4 includes a CPU 5 and A large number of keys 6, an input/output interface 7, a buffer memory 8, and a serial An input/output interface 9 and a display device 10 such as an LCD are provided. Ru. Serial input/output interface 3 and keyboard device of computer main unit 1 It is connected to the serial input/output interface 9 of 4 by a connection cable 11. There is.

[0007] FIG. 2 is a plan view of the keyboard device 4, and the keys 6 are shown in the case 1 of the keyboard device 4. The display device 10 is operably installed in the case 13, and the display device 10 is visible in the case 13. It is set up like this. Next, the operation will be explained. The signal from the key 6 is sent via the input/output interface 7. is input to the CPU 5 as input data, and the character code for the pressed key is input to the CPU 5 as input data. is stored in the buffer memory 8 and corresponds to the contents of the buffer memory 8. A character is displayed on the display device 10. CPU 2 of computer main unit 1 is the key If the data from the board device 4 can be accepted, the contents of the buffer memory 8 are The contents are serial input/output interface 9, connection cable 11, and serial input/output interface. is input to the CPU 2 via the interface 3. The battery supplied to CPU2 The contents of the file memory 8 are erased. The key is pressed while CPU2 is performing complex arithmetic processing, etc. If the data from the board device 4 cannot be accepted, the signal from the key 6 is The corresponding data are sequentially stored in the buffer memory 8. Therefore, normal condition Then, the contents of the buffer memory 8 are instantly rewritten and displayed on the display device 10. I cannot confirm the displayed content because the time it is on is extremely short, but the computer main unit 1 When PU2 is performing processing that takes a long time, the contents of buffer memory 8 are retained. Therefore, the contents of the buffer memory 8 can be confirmed on the display device 10. of confirmation If you find a typo, etc., you can cancel by operating the cancel key of keys 6. The contents of buffer memory 8 will be erased, so operate key 6 anew to enter the correct information. Just enter the content.

[0008] Please refer to the flowchart in Figure 3 for the operation of the CPU 5 to realize the above operation. I will explain. First, in step S1, it is determined whether or not there is an input from the key 6, and the input is performed. If there is enough power, the process advances to step S2 and the input data from the key 6 is stored in the buffer memory 8. Store in. Next, proceeding to step S3, the contents of the buffer memory 8 are transferred to the display device 1. Display it at 0. Next, the process proceeds to step S4, where the input data is stored in the buffer memory 8. It is determined whether or not it is stored, and if it is stored, the process proceeds to step S5 and the computer is Determine whether the CPU 2 of the computer main body 1 is in a state where it can accept input data. do. If it is in a state where it can be accepted, the process advances to step S6, and the contents of the buffer memory 8 are Connect the serial input/output interface 9, connection cable 11, and serial input/output interface. The data is transferred to the CPU 2 via the interface 3. Next, proceed to step S7, After erasing the contents of the buffer memory 8 transferred to the CPU 2, the process returns to step 1. In step S5, the CPU 2 of the computer main body 1 can accept input data. If it is determined that there is no current state, proceed to step 8 and check if there is an input from the cancel key. If there is an input, the process advances to step S7. If there is no input, step S1 Return to If the input data is not stored in the buffer memory 8 in step S4, If it is determined that this is not the case, the process returns to step S1. Input from key 6 in step S1 If it is determined that there is no one, the process advances to step S4.

[0009] In this way, you can visually check the contents of the buffer memory 8, so you can avoid typos. Easily correct errors.

0010

[Effect of the idea]

As explained above, according to the present invention, data input using keys is temporarily stored. In a keyboard device equipped with a buffer memory for storing A display device is provided to display the stored data, and the data can be displayed and canceled. The contents of the buffer memory can be erased by key operation, so Since the contents of the input buffer memory can be visually confirmed, typos can be easily detected. This has an excellent effect in that it is possible to easily correct the errors.
