RU2455677C2 - Multifunctional keyboard - Google Patents

Abstract

FIELD: physics.

SUBSTANCE: device is such that each key of the multifunctional keyboard is divided into opaque sections through which the bottom parts of which light-emitting diodes are threaded, said light-emitting diodes being electrically connected into groups of simultaneously illuminating light-emitting diodes, and the top part of each section has inner grooves into which replaceable translucent colour slides are inserted, said slides having the necessary opaque symbols deposited on them; semiconductor screens are worn on top on open parts of each key to project onto them from downwards symbols displayed on the slides illuminated by the illuminating light-emitting diodes of the selected sections of the keys.

EFFECT: multifunctionality of the keyboard.

Description

The invention relates to controls for systems and assemblies, can be used as a keyboard for computer technology.

The keyboard of a keyboard computer is known, in which there are keys for entering data into a computer "The Great Soviet Encyclopedia. M.," The Soviet Encyclopedia ", 1973, volume 12, p. 259.

The disadvantage of this keyboard is the lack of functionality.

The technical result of the invention is to provide the keyboard with multifunctionality.

This is achieved by the fact that each key of the multifunctional keyboard is divided into lightproof sections, through the lower parts of which there are LEDs that are electrically connected to groups of simultaneously turned on LEDs, and the upper part of each section has internal grooves into which interchangeable translucent color slides are inserted with the necessary with opaque symbols, translucent screens are put on top of the open parts of each key to project on them from below the symbols depicted on on slides illuminated by the LEDs of the selected key sections.

The invention is illustrated by drawings, where:

- figure 1 is a General top view (with the translucent screen removed) of a multi-function keyboard key;

- figure 2 is a section of a key along aa.

The multifunctional keyboard has a housing 1, in which keys 2 are installed with the possibility of a fixed small-amplitude reciprocating movement. Each key 2 is divided by partitions 3 into lightproof sections, through the holes 4 in the lower part of which LEDs 5 are inserted, electrically connected into groups that are switched on simultaneously by command multi-function keyboard operator. The upper parts of the opaque sections of the keys 2 are overlapped with interchangeable translucent color slides 6 with the necessary opaque symbols (letters of various alphabets, Roman and Arabic numbers, punctuation marks, etc.) applied to them.

The color of slides 6 is selected depending on the purpose of one or another group of keys 2 of the multifunction keyboard. Slides 6 are inserted into grooves 7 made inside the opaque sections of the keys 2. Translucent screens 8 are put on top of the keys 2 to project on them from below the characters printed on one or another slide 6 of the keys 2.

Work on the multifunctional keyboard is as follows.

The operator turns on the LEDs 5 of the selected group of key sections 2. On translucent screens 8 of keys 2, rays of light are projected through the colored slides 6 of the corresponding light-tight sections of the corresponding keys 2 highlighted by LEDs 5, as a result of which symbols printed on slides 6 are projected on the translucent screens 8. The fields of translucent screens of 8 keys 2 are highlighted in the color of the corresponding slide 6.

When you press one or the other key 2, information about one or another character is entered into the computer.
