Abstract

PURPOSE:To reduce erroneous input by visually grasping only characters which are inputted selectively when a shift key is pressed or not pressed. CONSTITUTION:At the front edge of a keyboard 6, lamps 3 and 4 or red and blue are provided, and turn on alternately with a shift key 1. Each key 2 has a character 7 displayed in blue and a character 8 displayed in red, and the character 7 or 8 is inputted by pressing the shift key 1 in combination. When the character 8 is displayed with the shift key 1, and blue lamp 4 turns on and when the character 7 is inputted, the red lamp 3 turns on. For example, when the character 8 can be inputted, the character 7 is masked with light from the blue lamp 4 and only the character 8 is read. Therefore, characters to be inputted through the combined operation of the shift key 1 are made evident to prevent errorneous input.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to system products such as microcomputers and word processors using microcomputers.
Used to visually capture only the characters that can be selected by pressing or not pressing the shift key from among the multiple input characters displayed individually (i.e., masking non-target characters) The present invention aims to provide a keyboard that reduces input errors by users. As microcomputers and system products such as microcomputer-based word processors become popular,
General consumers now have many opportunities to operate keyboards for inputting commands and programming. On the other hand, product designers aim to reduce the number of keys on the keyboard by introducing shift keys as much as possible in order to reduce costs and improve reliability. (This is because mechanical parts such as keys are often the cause of failures.) However, general users are not accustomed to using keyboards, so when entering input by operating the shift key, multiple displays are displayed on the same key. The disadvantage is that it is very difficult to recognize which character is being shifted and inputted when the number of keys increases.

Conventionally, a user searches for a character to input using keys on a keyboard, determines whether or not the character is a shift input, and inputs the character by pressing the corresponding key while holding down the shift key. In this case, it is necessary to judge whether or not the required character is ready to be input, which has several drawbacks.

The present invention aims to eliminate the above-mentioned drawbacks, and its gist is to display the color on the key (21) for each character group that can be printed by operating the shift key (1). 1), the corresponding shift key (1)
This is a keyboard (6) characterized in that a spotlight is irradiated onto the characters to be printed by the operation of ), thereby making it clear which characters can be printed.

Hereinafter, the present invention will be explained based on an illustrative example.

In this embodiment, red and blue lamps (31, 141) that illuminate the entire surface of the keyboard are provided at the front end of the keyboard (6), and the lighting lamps change by pressing the shift key (1).

The key (2) indicates that the characters displayed in blue (7) and the characters displayed in red can be entered, and by operating the shift key (1), the characters displayed in blue (7) can be entered.
Alternatively, the character (8) displayed in red can be entered. When the character @) displayed in red can be input by operating the shift key (1), the blue lamp (4) lights up, and when the character displayed in blue (7) can be input, the red lamp (3) lights up. lights up.

Then, by operating the shift key (1), the red character (8)
When inputting is possible, the blue characters (7) are masked by the light emitted by the blue lamp (4), and only the red characters (8) can be read. Also, when the blue character (7) is enabled to be input, the red character @) is masked by the light emitted by the red lamp (3), and only the blue character (7) can be read, such as 0 or more. The user can input the characters by operating the shift key (1), and since the characters can be clearly recognized, there are fewer erroneous inputs.

In the above embodiment, the method of masking the characters that are not printed is S, but conversely, a bean ball corresponding to each character is placed inside the key, and the characters that can be printed by operating the shift key are selected. You can also make it illuminated by a miniature ball.

As described above, according to the present invention, the user can clearly recognize the characters that can be input by operating the shift key, so there is little risk of inputting the characters.

Claims (1)

[Claims] (1) For each character group that can be printed by operating the shift key (1), the key (2) upper lip ζ color is displayed, and by operating the shift key (1), the number of characters that can be printed by the operation number of the shift key (1) is displayed. Shine a spotlight on the characters that should be written,
A keyboard characterized by making the characters that can be typed out clearly.
