Abstract

PURPOSE:To display the contents of a key function by updating the data of the contents of a function displayed on a keyboard for a function displaying memory at the time of depressing a program execution key or a function changing key and displaying the function data on the key itself. CONSTITUTION:At the time of raising a system, an initial display pattern is transferred from a fixed memory 23 to a preceding display data memory. When a function display changing key is depressed, the function display data are transferred to the preceding display data memory and the preceding display data are displayed on the key. In the case of changing the function display by a program, the data outputted from the program are transferred to the preceding display data memory and the preceding display data are displayed on the key. Thus, the meaning of each key can be displayed on the key itself and a misinput can be suppressed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a keyboard data input device.

[Conventional technology]

Figure 3 2 and Figure 4 are diagrams of a part of the conventional keyboard data input device. When the 7&hi key is pressed, the function changes.

Next, the operation will be explained. The display of the function contents of the key (2) whose function contents change when the function change key 11) is pressed is conventionally stamped or embedded on the side or around the key itself. This was handled by the user consciously rereading the key each time it was pressed, or by displaying the function of the key on the CRT when the function was changed by the program.
By pressing a key, the contents of each key are changed as shown in Figure 4, but the function display as shown in Figure 4 is not written on the keyboard and the user has to read the manual. You must enter it while checking it.

[Problem to be solved by the invention]

Conventional keyboard data input devices are configured as described above, so when pressing a function change key 11), the user always has to check what function is assigned to each key, whether it is on the CRT or the key itself 3. , you have to read the function details engraved around the key,
There is also the problem that if you press the wrong function change key, you will not know what function is assigned.

There is also the problem that if there are a large number of one function key, the display cannot be partitioned on the CRT.

This invention was made in order to solve the above-mentioned problems, and it is possible to display the contents of the function to be changed when a program is executed or a function change key is pressed on the corresponding key itself, and it is also possible to An object of the present invention is to provide a keyboard data input device that can change the contents of functions displayed on the keys themselves in response to commands.

[Means to solve the problem]

The function explicit type keyboard data input device according to the present invention changes the contents of the function display memory of one function key to the contents to be displayed when a program is executed or a function change key is pressed. The function-explicit type keyboard data input device is designed to display the contents of the function display memory on the corresponding keys at regular intervals, and the function display memory can be rewritten by executing a program. This is what I did.

[Effect]

The keyboard data input device according to the second aspect of the present invention changes the data of the function content shown on the keyboard in the memory for displaying one function by executing a program or pressing a function change key, and displays the one function data on the key itself. It displays the contents of the functions assigned to. This changes the content of the function assigned to the key.

〔Example〕

Embodiments of this invention are illustrated below. In Figure 1, ■ is a signal in response to the function change key being pressed;
22 is a signal input as the program is executed;
This is an area where contents g to be displayed on the function keys and information output from the program and output to the function keys are stored in advance. (to) outputs the contents of the memory in ■ to the key display device in @.
4.

First, when starting up the system, the keyboard data input device transfers the initial display pattern from the fixed memory to the memory of the previous display data. Next, check if the function display data was pressed.

When pressed, the corresponding function display data is transferred to the memory of the previous display data. Then, the previous display data is displayed on the key. - If the function display is changed by executing the program, the program transfers the output data to the memory of the previous display data and displays the previous display data on the keys.

Further, in the above description, a keyboard data input device has been described, but if the selection switch is simply a push button type, the same effects as in the above embodiment can be obtained. Roughly press one function selection key or.

By illuminating only the necessary function buttons as the program is executed, it is possible to prevent erroneous operations and create a device that allows even inexperienced users to perform appropriate tasks at all times. .

〔Effect of the invention〕

As described above, according to the present invention, the meaning of each key can be displayed on the key itself, and its contents can also be changed from a computer.
Since the system is structured so that inputting errors from the function keys of the manual key device can be avoided, it is also possible to change the explanation content quickly and inexpensively.

[Brief explanation of the drawing]

FIG. 1 is a block diagram showing a function-explicit keyboard data input device according to an embodiment of the present invention, FIG. 2 is a flowchart showing the operating principle of the present invention, and FIGS. 3 and 4 are conventional keyboard data input devices, respectively. FIG. 2 is a plan view showing the device. In Figure 2, 11) is a function change key - 1+2) is a key whose function content changes, Ql is a function change key press signal, ■ is a program output signal, is a memory, example is a keyboard data output device, @ is a keyboard It is a display device. Note that in the two figures, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Claims] (1) A function-clarification type keyboard data input device characterized in that when a program execution or function change key is pressed, the contents of the function display set to each key can be displayed using arbitrary characters and symbols.
