RU32303U1 - KEYBOARD FOR PERSONAL ELECTRONIC COMPUTER MACHINE - Google Patents

Description

Technical field

The device relates to the field of computer technology and can be used to enter information into a personal electronic computer.

State of the art

An analogue of this technical solution is a device for complete data input and control; their commands with the help of; a small amount of data in the quick print mode, which contains keys, a front panel with a graphical table (US patent No. 5184315 class G06F3 / 023). A disadvantage of the known device is the difficulty of entering data due to the need for several taps to enter one character.

The closest analogue (prototype) to the claimed technical solution is a universal KEYBOARD for a stationary personal electronic computer (IBM PC) (see, for example, A. Miklyaev, IBM PC User Manual, published by Altex-A, Moscow 2000, section 1.2.14 p. . 37 - 40).

Almost identical modifications to the universal keyboard are produced by all firms specializing in the production of personal computers (NECs) compatible with the IBM PC. Modern computers use a keyboard with 104 keys (on

portable (note-book) - 84/86 keys). The location of the Latin letters corresponds to a typewriter using the Latin alphabet, and Cyrillic letters - Russian.

When working on a standard keyboard, to enter numbers, lowercase characters, printed at the bottom of the button, as well as lowercase letters, just press the corresponding key. To enter uppercase characters at the top of the key and capital letters, you must first press the Shift key and, without releasing it, press the desired key. There is another way to enter uppercase letters: press and release the Caps Lock key, which captures uppercase letters, numbers and uppercase characters. This mode is canceled by pressing Caps Lock again.

The disadvantage of the prototype is the need for successive pressing of two keys when typing characters in upper case and capital letters on the line of alphanumeric keys, which negatively affects the speed of information input.

Utility Model Essence

The well-known keyboard for a personal computer contains a standard set and arrangement of keys, control circuits and interfaces with a PC port.

The purpose of this technical solution is to increase the input speed of character and alphanumeric information by reducing the number of keystrokes.

The proposed keyboard further comprises a pair of an optical emitter located at one end of the line of symbol-digital keys, and an optical receiver at the other end of this line, located above the top edges of the keys at a distance that allows the operator’s finger to overlap the line of the optical axis connecting

centers of the optical transmitter and receiver, to switch the keys to upper case.

The keyboard also contains a controller, to the input and output of which a receiver and emitter are connected, and the input-output is connected to the port of the PC system unit.

List of drawings

In FIG. 1 shows an enlarged structural diagram of a keyboard for a personal electronic computer.

In FIG. 2 shows a general view of the keyboard for a personal electronic computer.

An example embodiment of a utility model

The keyboard of a personal electronic computer (Fig. 1, 2) contains a housing 1 with a universal (standard) set and placement of keys 2, a control circuit and interface with an IBM PC PC port, an optical emitter 3, an optical receiver 4, controller 5. A standard keyboard is connected to the PC via interface 6, and an additional controller via interface 7.

The standard keyboard contains 104 keys.

All keys on the keyboard can be divided into four groups:

- character or alphanumeric keys - by clicking on which, the operator enters a particular character. Space between words, numbers, etc. enter the large (long) Space key located in the bottom row (in Fig. 1, 2 the inscription is not applied);

-special - the computer performs a specific action. These are the Enter, Esc, Tab, Backspace (-), Ins, Del, Print Screen, Pause keys;

)

window)), and teki (a schematic illustration of the menu); shift keys or shift keys - Shift, Ctrl, Alt, Caps Lock, Num Lock and Scroll Lock;

- function keys - from F1 to F12 inclusive.

In the proposed keyboard, at the ends of the line of alphanumeric keys, an additional pair of optical emitter 3 and optical receiver 4 is installed so that the connecting their optical axis passes in the immediate vicinity of the top edge of the keys so that the optical axis can be overlapped in if necessary, with the operator’s finger when pressing any key in the ruler. Thus, the upper case is selected simultaneously with a set of characters with the touch of a finger. When you remove a finger from a symbol key, the state of the lower case is restored automatically.

Similarly, capitalization is selected. The difference is that the overlap of the optical axis of the pair of optical emitter and receiver requires the participation of another operator’s finger. In this case, the overlapping of the optical axis is possible anywhere above the line of symbol-digital keys.

Reducing the number of movements of the operator’s hands leads to an increase in the speed of typing information when using the proposed keyboard.

Industrial applicability

This technical solution is industrially feasible, it reduces the number of keystrokes of two keys when entering uppercase characters and capital letters, i.e. increases the speed of entering information.
