The invention relates to devices for visual digital, textual or graphical information and can be used in various technical fields.

The purpose of the invention is to increase the speed and accuracy of the scoreboard.

FIG. 1 shows the structure of a bulletin board; a plan; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; Fig. 4 is a structural control circuit of a bulletin board.

The information board contains panel 1, on which racks 2 with center symmetrically arranged holes 3 are fixed; two-color indicator elements with segments 4 made in the form of hexagonal plates that can be rotated around their longitudinal axes 5.

A different combination of segments 4 with the same color gives a certain sign.

Each segment 4 is provided with a permanent magnet 6 and a ballast element 7, ensuring the horizontal position of the segment 4 relative to panel 1.

Under each segment 4 opposite the permanent magnet 6 there is an electromagnet 8 with poles 9, which reach a level of permanent magnet 6.

To control the information display, the latter contains a software device 10, a switch 11 with a power source 12. The outputs of the switch 11 are connected to the windings of electromagnets 8.

Information board works as follows.

In the initial position, the segments 4 have a non-working color, for example white, and the display does not carry any information.

If it is necessary to display the required sign information, for example, the digit 5 (Fig. 1), the software device 10 receives the appropriate control signals through the switch 11 to the windings of the respective electromagnets 8, under the influence of which the corresponding segments 4 are rotated around the axes 5 by

180 ° and will have a different color, such as black.

The rotation of the segments takes place as a result of the interaction of the permanent magnets 6 and the poles 9 of the electromagnets 8.

The implementation of the indicator elements in the form of rotating segments, controlled by the joint action of permanent magnets and electromagnets, allows to obtain

an information board with a large capacity of displayed digital, textual and other information and a large amount of information due to an increase in the number of segments and their sizes. Proposed Scoreboard

economical in terms of power consumption. Electricity in it is consumed only at the time of the change of information.

Claims (1)

Invention Formula An information board containing a panel on which two-color indicator elements are installed with segments made in the form of hexagonal plates that can be rotated around their longitudinal axes, permanent magnets located on the plates, and control elements in the form of electromagnets whose windings are outputs board for connecting to switch outputs, which are due to the fact that, in order to improve the speed and accuracy of the scoreboard, in it two-color indicator elements contain ballast elements located on plates parallel to the permanent magnets, parallel to which are the poles of electromagnets mounted on both sides of the plates. 1 6-6 ftsg.Z X / ten
