The invention is illustrated in the following examples of its implementation, illustrated by drawings, which presents the following:

figure 1 - functional diagram of the device;

figure 2 - schematic representation of the device corresponding to the first variant embodiment of the invention:

(a) top view, b) side view in section along the line a-a in (a);

figure 3 - schematic representation of the device corresponding to the second variant embodiment of the invention;

4 is a schematic representation of the device corresponding to the third variant embodiment of the invention.

As shown in figures 1, 2, the input device information contains the panel 1, which is a keyboard containing keys 2, many of the radiators 3, 4, merged respectively in the first and second blocks of emitters, and many of the receivers 5, 6 radiation combined respectively in the first and second blocks of the radiation receivers. In the embodiment of figure 2, the keyboard consists of two Klah is ish 2.

The input keys 2 and the inputs of the first and second blocks of emitters 3, 4 form the input 7 of the device to enter information. The outputs of keys 2, and the outputs of the first and second blocks of the receivers 5, 6 radiation form the output 8 of the device to enter information.

In the embodiment shown in figure 2, the emitters 3 and 4 of the first and second blocks of emitters and receivers 5, 6 of the first and second blocks of detectors to form pairs of the plurality of optical beams 9. Optical beams 9 can be held above the work surface 2 keys, below the level of the working surface of the key, key, key, and also to pass through a through hole in a key or through a recess in the form of a trough in the key.

Figure 2(b) shows a side view in section along the line A-a in figure 2(a)illustrating the execution of the keys 2 and the relative placement of the keys 2, the emitter 3 and the receiver 5 of the radiation. In this embodiment, the optical beam 9 pairs of emitter 3 and the receiver 5 of the light above the work surface 2 keys.

Figure 3, 4 shows schematic views illustrating possible embodiments of the claimed device for different configurations layout keyboards obtained from a standard keyboard.

As the radiation receivers can be used digital optical matrix or digital videoke the career.

The device can operate in the mode coordinate of the device or keypad mode. The first block of the radiation receiver 5 tracks movement of the working body (finger) on the Y-axis, the second set of receivers 6 radiation tracks movement of the working body on the X-axis, and the two - axis Z. When the operating body is moved over the surface or slides on the surface of the key 2, the blocks of the receivers 5, 6 radiation determine its coordinates and the device operates in the coordinate mode. If there is a pressing 2, the device is operating in keypad mode.

Pressing a finger on the desired symbol in the relevant work area key 2 at the output of the receivers 5, 6 radiation are formed corresponding codes.

Blocks receivers 5, 6 radiation can also determine the mutual position of the fingers or recognize how the finger is pressing. Pressing different fingers (or fingers on different hands) on the same key or the working area of the keys can be extracted at the output of the receivers 5 and 6 different codes that can be programmed to correspond to each finger symbols. For example, pressing the same key alternately with each finger of two hands, you can extract ten characters. You can encode the device so that while re is eminii two fingers (index and middle) on the surface of the keys 2 the device will work in the coordinate mode.

The device can be programmed so that if the key worked from external vibration without the participation of the finger, such a code will be invalid.

Described in more detail below option exercise device for inputting information with two keys 2 with a square working surface and fourteen optical beams (five of which longitudinal and nine transverse), which are above the working surface of the key 2 in parallel to the respective sides of the keys (figure 2). Longitudinal optical beams formed by blocks of 3 sources of radiation and the radiation receiver 5, and the transverse optical rays - blocks of the radiation sources 4 and receiver 6 radiation. In this embodiment, the blocks of the sources 3, 4 radiation and blocks receivers 5, 6 radiation is performed in the optical range.

The key surface is divided into 25 zones (5*5), each of which is marked with the appropriate symbol.

Pressing the working body (finger) one of the key 2 in the area of the passage or crossing the optical rays or near key 2 (available for fingers) will stop the corresponding optical rays and the output 8 of the device produces a corresponding key code 2.

For example, pressing the left key in the zone number “1” is interrupted by the second (top) longitudinal optical Lou and output 8 device appears corresponding to the digit “1” code. Pressing the number “2”, apart from the second longitudinal beam is interrupted and the first (left) transverse beam and the output device generates the appropriate code. When pressing in the area of the symbol “CL” is interrupted, only the first transverse optical beam.

Similarly develop codes of all the characters printed on the keys.

Clicking on the zone characters “Esc” or “Ent” closed contacts of keys without interrupting the optical rays.

The interruption of the first longitudinal beam (without pressing) depending on what key it is blocked, means the appearance at the output 8 of the device respectively the left or right of the command code “Shift”key.

When pressing in the area of one of the figures, when the finger is over the upper edge of the key, which causes the interruption of the first longitudinal optical beam at the output of the device appears appropriate code symbol(!, @, #, $, %, ^, &, *, (,), _, +). On a normal keyboard this is only possible with pre-Shift.

When pressing the left key in the appropriate area when working body (finger) is past the right edge of the key and causes the interruption the fifth transverse optical beam at the output of the device appears appropriate code symbol (“-”, “Note”, “left Shift”, “End”, “Pg Up”).

Clicking to the right of CL is hanging in the corresponding area, when working body (finger) stands for the left edge of the key and causes the interruption the fifth transverse optical beam at the output of the device appears appropriate code symbol (“=”, “Shift up”, “right Shift”, “Shift down”, “Pg Dn”).

Thus, the device consisting of the two keys, provides the ability to retrieve one of the seventy-two codes and two “Shift” one touch keys with one finger. Neighboring keys do not interfere with pressing the selected key.

Additional codes on the output device, you can also provide movement of the finger. For example, if you move the finger between the two keys up and down, overlapping the fifth transverse optical beam and the corresponding longitudinal optical beams, the cursor will move up and down. If you move the finger over the top edge of the keys, overlapping the first longitudinal optical beam and the corresponding transverse optical beams to the left or right, the cursor will move left-right. In this case, the previously described methods of retrieval codes to control the cursor when you press a key can be replaced with other ways to extract the necessary codes (Insert, Ctrl, Alt etc).

The possible option of making additional codes method touch key 2 finger rokiv one of its working areas with subsequent removal of the finger (without pressing 2). For example, the touch keys in the zone of the letter “a” will cause the output device codes corresponding uppercase letter “A” (with Shift), etc.

You can interrupt multiple optical axes of not one, but a large number of fingers, then at the output 8 of the device significantly increases the number of key codes 2.

Perhaps structurally to accommodate transverse optical beams in such a way that in the initial state, they will be blocked key and pressing the key will cause of their recovery. All or part of the optical rays can pass through the openings under the working surface of the keys. In these cases, the keys may be contactless, because the state of the key (pressed or unpressed) in this case is determined by the reconstruction and (or) termination of the respective optical beams.

Figure 3 and 4 illustrate respectively the embodiments of the devices with eighteen keys and twelve optical beams and twelve keys and thirteen optical rays which are similar purpose, two-key device 2.

Shown in figure 3 embodiment of the keyboard with 18 keys each secondary key is divided into eight work areas corresponding to the keys of a conventional keyboard. In this embodiment, the main characters on the keys RA is medeni relative to each other, as in a conventional keyboard. Area under the fingers and the distance between the centers of the main characters of the series (f, s, b, a, p, R, o, l, q, W, e) pressing keys sustained, as on a normal keyboard. This keyboard allows the user to work ten fingers, as on a normal keyboard. Thus the distance to the neighboring characters serviced by each finger of one hand, is significantly reduced in comparison with the regular keyboard that enables faster data entry.

In figure 4 presents a similar implementation keypad with 12 keys, each secondary key is divided into 12 zones, which reduces the movement of the forefinger and middle finger of each hand when working on the keyboard.
