Description

The invention will find application in the practice of educational work of institutions for the deaf and dumb.

Devices for interviewing blind and deaf and blind people, a keyboard for entering information to a blind person, a conversion unit and electromechanical six-pin signaling devices, which reproduce relief-point signs read by blindly deaf and blind, are known.

Known devices do not automatically log the conversation.

The described apparatus is characterized in that it is provided coupled electrically semiklavishnymi keyboards for inputting informanii deaf-blind in signs braille system with an arrangement kldvish as in typewriters for the blind, iconic indicator for schityvapi sp cheslyshaschim nnformatsin coming from the deaf-blind, and the recording apparatus automatically captures the course of the conversation on the tape in the signs of the relief-point font, connected in parallel.

This allows you to simplify the input of information for the blind and deaf and automatically record the conversation.

the elemental sign indicator highlighting the characters in the Braille code; in FIG. 3 is an electrical diagram of an individual console; FIG. 4 is an electrical circuit of a recording device; FIG. Figure 5 shows schematically the recording part of a recording device. FIG. 6 is a schematic representation of the transporting mechanism of the recording device; FIG. 7 is an electrical diagram of a keyboard of a central console and a conversion device.

FIG. 1 the following notation is accepted: / - source of short-circuit current; 2 - central control keypad and conversion device; 3 - sign indicator; 4 - recording device; 5 - individual remote control; 6 - negative pole of the current source; 7 - positive pole of the current source; 8-M are interconnection points of the device blocks.

As can be seen from FIG. 1, blocks 2, 3, 4, 5 through points 8-14 are interconnected in parallel. At several individual consoles, they, like the individual console 5, are connected to common connecting lines. In FIG. 2 shows the simplest sign indicator with six incandescent lamps, which are located as points of a six-point Braille: lamp 15. Corresponds to the first point

point; lamp 17 - the third; 18 - the fourth; 9 - that; lamp 20 - the sixth point of six. Contact points 6, 8-13 are designated as in FIG. one.

FIG. 3, it can be seen that the individual console contains seven push-button keys 21-27, which are controlled by pressing the keys of the seven-key pad, and six electromagnets 28-33, which control the movable pins of the electromechanical alarm devices. Button key 21 corresponds to the first point; 22 - the second; 23 - the third; 24 - the fourth; 25 - that; 26 - the sixth point of six. Key 27 is associated with a spacebar key. Electromagnet 28 corresponds to the six point six point; 29 - the second; 30 - the third; 31 - the fourth; 32 - of that, 33 - the sixth point of six. Contact points 6-14 are designated as in FIG. one.

FIG. 4 is given an electrical circuit registering; its devices, where 34 is an electromagnet, controlling a punch and recording: its devices, corresponding to them, to the first point of six; 35 - the second; 56 - the third; 37 - the fourth; 38 - the first; 39 - the sixth point of six; 40 - electromagnet transduced; its mechanism.

FIG. 5 schematically shows a part of the recording, its devices, where 41 42 are the cores of electromagnets 36 and 39 (in FIG. 4); 43-44 - coils of electromagnets 36 and 39; 47- 48 - movable pins-punches, corresponding to the third and sixth points of the braille six-piece; 45 - return spring; 50 fee; 51 is the matrix; 52 - a paper tape.

FIG. 6 shows a schematic graphical mechanism of the register; its devices, where 53 is the coil of an electromagnet 40 (but FIG. 4); 54 - electromagnet core 40; 55- measles of electromagnet 40; 56-dog ratchet device; 57 - ratchet wheel; 58 - retainer; 59 - working spring; 60 - clamp spring; 61 - transporting drum; 62 - pressure roller; 52 - a paper tape.

FIG. 7 is an electrical diagram of the keyboard of the central console and the converter, where 63 are the button keys associated with the sign keys; 64-65 diode arrays; 66 — keys controlled by register switch keys; 67 — register switch relay coil; 68 - switching contacts of the relay 67; 69 is a key controlled by a spacebar; 6 is a point associated with the negative pole of the current source; 7 is a point associated with the positive pole of the current source; The 8-output point of the diode array corresponds to the nerve point of the six-point Braille, 9 is the output point corresponding to the second point six-point; 10 third point; 11 - the fourth point; 12 - the point; 13 - the sixth point of six; 14 - exit point from the spacebar key.

The qi is entered by the operator of the central console by pressing associated with the key 63 keys. It enters the diode arrays 64 or 65 which translate

letters, numbers and other signs in the electrical signals that occur at points 8-13 and are adequate to alphanumeric, digital and other characters of the relief-dotted font. For the transfer of characters, relate p1, nhs to upper case

(+, 1, 2, 3, 4, 5, 6, 7, 8, 9, O, -, ...), as well as when working on a typewriter, one of the switch keys of the registers associated with the keys is first pressed 66, then the corresponding key, with the keys 63.

When you press one of the keys (key 66 closes the relay circuit 67, as a result, the switching contacts 68 will disconnect the lower six buses of the matrix 65 from the horizontal buses of the matrix 65 and connect the upper six buses to it

tires of this matrix.

The spacebar key on the keyboard, associated with key 69, when pressed, sends a positive pulse to point 14.

As can be seen from FIG. 1, 2, 3, 4, 7, electric

the signals arising at the output points 8-13 of the diode matrix 65 simultaneously arrive at the points 8-13 of the sign indicator 3, the recording device 4 and the individual consoles 5.

In the case of, for example, keys with the "M" key 63 with it, the key 63 is closed, and the voltage from the positive pole of the current source will go to the vertical bus and through three diodes will be transmitted to the output

points 8, 10, 11. In this case:

On the sign indicator 3, the lights will start to glow 15, 17, 18, the sign corresponding to the Braille letter “M. On the individual consoles work

electromagnets 28, 30, 31 and I will act on

The movable pins of the detectors will create

the end of the pins are relief-point mark

"M.

On the recording device will work

The electromagnets 34, 36, 37, will lift up the pins of the recording device (Fig. 5), which with the help of the matrix 61 issued on the tape 52 relief points forming the Braille sign “M. Simultaneously, the incoming signal through the diodes (Fig. 4) will go to the electromagnet 60, will trigger it and cocking the ratchet mechanism (Fig. 6) of the reverse action. Upon termination of the signal, the electromagnet will release, and the doggie of the storage mechanism 56, due to the elasticity of the spring 59, will turn the ratchet wheel 57 by one tooth. The transporting drum 61 will move the belt 52, which is clamped between it and the pressure roller 62, one interval.

in the same way, the transport mechanism will operate when the keys are closed and the spacer keys 69 (Fig. 7) and 27 (Fig. 3).

By pressing the corresponding keys on the seven-key keyboard. When transmitting, for example, the letters "M" on an individual zero, three keys are simultaneously pressed, closed, the keys 21, 23, 24 (Fig. 3). As a result of this, as when pressing the “M keypad of the central console, the voltage from the positive pole of the current source goes to the offended points 8, 10, 11 of blocks 2, 3, 4. This will cause the same effect as pressing the“ M .

Thus, with "direct communication, information entered by means of pressing keystrokes on the keypad of the central console, is converted into characters in a relief-dotted font, read deaf-blind, and, during" feedback, information is entered deaf-and-dumb through a braille keyboard and reproduced by a character indicator whose signals are read by sight. At the same time, the logging of information going both in the forward and in the reverse direction is carried out. In the proposed device, instead of a six-element signed indicator, any other one can be used, coupled with the general circuit through the corresponding additional converter.
