Description

The invention relates to the field of electronic technology, namely to information input devices, for example computer keyboards.

A well-known keyboard adopted as a prototype, comprising a housing, keys with symbols on the outer surface, provided with internal illumination and mounted on the housing (US, 6720892, 2004)

As the disadvantages of the known technical solutions, you can specify the following. In the well-known solution, the backlight is implemented in one color and under the entire button, therefore when using a keyboard with keys containing, for example, letters of the Russian and Latin alphabets as symbols, both layouts - Russian and Latin are highlighted at the same time. This circumstance allows us to say that when changing the layout in the process, the user has difficulty finding the right character.

The technical result, which the utility model aims to achieve, is to increase input speed in low light conditions due to the fact that each individual character of the used layout is highlighted, for example, letters of the Latin alphabet, and the alternative layout is not highlighted and, therefore, does not distract the user .

The specified technical result is achieved by the fact that in the information input device comprising the housing, the keys with symbols on the outer surface, provided with internal illumination and mounted on the housing, the keys are configured to separately illuminate each symbol.

The backlight can be made in the form of an LED, and the means for delivering light to each symbol is light fibers or light films.

The internal key cavity can be divided by partitions into parts, in each of which a backlight is placed.

The backlight can be made in the form of an LED.

The backlight can be made in the form of LEDs of different colors.

The information input device (hereinafter referred to as the keyboard) comprises a housing on which keys with symbols on an external surface are installed. The keys are provided with internal illumination of each of the characters located on it individually, i.e. characters are highlighted separately.

The backlight can be performed, for example, in the form of a single LED, and the means for delivering light to each symbol is light fibers or light films.

The backlight can be made as a separate LED for each character. In this case, the internal key cavity is made divided by partitions into parts, and an LED is placed in each of the formed cavities. The number of cavities formed by the partitions corresponds to the number of characters located on the outer surface of the key. LEDs, depending on the layout used, can have a different color, for example red and blue. How it works: when switching the layout (Russian / Latin), the “plus” power is selected: blue or red, and the “minus” is common. The general backlight switch is located on the keyboard body. To select the desired backlight level, a backlight control may be provided on the chassis.

The keys are made of transparent plastic, for example, by molding, then the surface of the key is painted, and the characters (e.g. letters)

engraved by laser, mechanical or chemical method. The result is transparent characters.

The keyboard works as follows.

In low light conditions, the backlight turns on.

Keys with switching layout.

When switching the layout, the illumination of one layout is turned on, while the second layout is not highlighted, i.e., for example, when the Russian layout is on, only the letters of the Russian alphabet are visible in the dark. The letters of the Latin alphabet are not highlighted and vice versa.

Switching the backlight when switching the layout applies only to keys with a double layout: all letters, a freestanding letter E and a slash key after a hard character, as well as numbers 2, 3, 4, 6, 7, which also have a dual purpose, depending from the layout (the upper part of the keys should be divided vertically, since the lower part of the key is the numbers displayed in any layout, and only the upper characters switch depending on the layout).

Backlit keys.

All other keys, i.e. those that work regardless of the selected layout are constantly highlighted when the backlight is on. This is a digital block of keys, upper keys (Esc, F keys, etc.), scrolling keys home, end, etc., Enter, Shift, etc., arrows, hot keys, etc. etc.
