Abstract

PURPOSE:To enable even a beginner to improve key input efficiency by inputting complicate combination from a keyboard by referring to key guide help information. CONSTITUTION:When a command for a key guide help is received from the keyboard 3 or a mouse 4, a key guide display part 2 displays the key guide help information on a screen 5. On a screen 5, various pieces of message and information from a data processor control part are displayed. The key guide help information is displayed by using a part of a display area 21 for various pieces of message as a key guide help information display area 22. When tabulation is necessary while a program is executed, a specific key on the key board 3 or the right button of the mouse 4 is depressed so as to know a key for the drawing the rule of the tabulation. A data processor control part 1 displays the key guide help information on the screen 5 through the key guide display part 2. The keys corresponding to the function of key operation for the ruling which is displayed on the screen 5 are inputted from the keyboard 3 by an operator.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input device for various data in a personal computer, and more particularly to a key input device that involves key operations using complex key combinations.

0002

[Prior Art] In conventional key input devices, key operations for complex key combinations are performed by memorizing the key combinations (combinations of "control keys and data keys, etc.") or by referring to an instruction manual. I needed to enter it.

0003

[Problems to be Solved by the Invention] With the above-mentioned conventional key input device, when there are many complicated key combinations for the operator (control key and data key, control key and control key and data key, control key and control key). The problem is that beginners are often unable to memorize special keys).

[0004] Even if such key combinations are memorized, the rhythm of the operation work will be disrupted until the user remembers the memorized keys, leading to inefficiency in key input. There was also the problem that if a wrong key input was made, a completely different operation would be executed.

[0005]

[Means for Solving the Problems] The key input device of the present invention has a program and a key guide display section that displays a key guide on the screen before an operator performs a complicated key operation during execution of the program. There is.

[0006]

Embodiments Next, embodiments of the present invention will be explained with reference to the drawings.

Referring to FIG. 1, in one embodiment of the present invention, a data processing device control section 1 controls the entire data processing device. The key guide display section 2 displays key guide help information on the screen 5 when receiving a key guide help command from the keyboard 3 or mouse 4. The keyboard 3 is a device for the operator to input various information, and is also a device for sending commands for key guide help. The mouse 4 is a device for the operator to select various information and give instructions, and is a two-button device for sending commands for key guide help. Various messages and information from the data processing device control section are displayed on the screen 5.

The outline of the key guide help information is shown in FIG.
As shown in FIG.
Displayed as 2.

The operation shown in FIG. 1 will be explained with reference to the schematic flow of key input operations shown in FIG. Here, we will explain what happens when an operator tries to plot a table on the screen and forgets to use the key to draw the borders of the table.

[0010] First, an operator starts the program, and while the program is being executed in step 31, step 32
In step 33, a specific key on the keyboard 3 or the right button of the mouse 4 is pressed in order to know the key to draw the borders of the table when tabulating the table. In response to this command, the data processing device control unit 1 displays key guide help information (22 in FIG. 2) on the screen 5 via the key guide display unit 2 in step 34. In step 35, the operator inputs from the keyboard 3 a key corresponding to the key operation function for drawing ruled lines displayed on the screen 5.

[0011]

[Effects of the Invention] As explained above, the present invention has the effect of improving key input efficiency even for beginners by inputting complex key combinations from the keyboard by referring to key guide help information. .

[0012] Furthermore, it is possible to eliminate the operational inconvenience of performing a completely different operation due to an operator's erroneous operation.
