Description

one

The invention relates to the field of office equipment, in particular typhotechnics, and is intended to display and perceive information in relief form by blind and visually impaired people by means of OS.

The aim of the invention is to increase reliability in operation.

FIG. 1 shows the device, a general view; in fig. 2 is a section A-A in FIG. one.

The device for the relief display of information comprises a housing 1, a pin 2, a spring 3, a winding 4 and the core 5 of the electromagnet, a spring 6, a washer 7 of magnetically rigid material magnetized along the axis, a sensor 8, contact pins 9 and the surface 10 of the display.

 Pin 2 is made of magnetically demanding material, magnetized along the axis, and thus has a strictly defined arrangement of the magnetic poles. The polarity of all the pins 2 is the same. To improve the identification conditions of the pin 2 and lower the threshold of its psychophysiological perception during osusanie, the tactile end of the pin 2 is controlled in the form of a cone with a top formed by a radius (0.1 - 0.25 mm. The pin 2 has a chromium-nickel coating. 4 electromagnets and sensors 8 are connected respectively to the outputs and inputs of an electromagnetically controlled control unit (not shown) for providing information and monitoring information output.

The device works as follows.

In the initial state (Fig. 2), the pin 2 and the washer 7, having their own magnetization, are adjacent to the strut core 5. When fed to the winding 4 from the control unit of electromagnets (not shown), the voltage of the corresponding polarity on the core 5 under the support surfaces Pin 2 and washers 7 form magnetic poles of the same polarity with adjacent poles of pin 2 and washers 7. Pin 2 and washer 7 are repelled from core 5 (Fig. 2, left).

Pin 2 rises above display surface 10.

There are two options for the device.

In the first embodiment, the voltage on the winding 4 is not relieved and the pin 2 is held in the upper position under the influence of the spring 3 and the mutual repulsion of the magnetic poles of the pin 2 and the core 5 (the same for the clamp 7); In the second variant, the voltage is removed from the winding 4} i and the pin 2 is held in the upper position under the influence of the force of the spring 3 (for the washer .7 - the spring b).

The washer 7, moving towards the sensor 8, changes its electrical characteristics. Scanning by the sensor control unit 8 produces a distending automatic monitoring of the information state of the pins 2 and, in this way, is carried out about 0,734.

Communication with the electromagnet control unit.

When a reverse polarity voltage is applied to the winding 4, the pin 2 and the washer 7, being attracted to the core 5, return to their original state, since magnetic poles opposite the poles of the pin 2 and the washer 7 are formed on the core 5 Using the sensor 8, the position of the pins 2 can be checked.
