Abstract
Abstract A teleindicator for information boards is described. The main characteristic of the teleindicator consists in comprising first means for the registration of input signals relating to an indication which has to be presented by the said teleindicator, second means adapted to process the signals from the said first means and to control third means which actuate, in a mechanical way, the display of the said indication by means of indicator elements.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
A teleindicator for information boards, comprising in combination, first means for the registration of input signals relating to an indication which has to be displayed by the said teleindicator, second arranged to process the signals from the said first means and arranged to control third means which actuate, in a mechanical way, the display of the said indication, by means of indicator elements, said third means comprising an electric motor and transmission mechanism for the transmission of the motion from the said motor to the said indicator means, characterized in that the said transmission mechanism comprise a mechanical transmission coupling periodically inactive while the electric motor is running, for the interruption of the transmission of the motion from the said motor to the said indicator elements, the said periodically inactive transmission coupling comprising an endless screw coupled to a gear, the profile of the said endless screw being such as to produce a rotation of the said gear only when corresponding to a section of the said profile.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
36 words
A teleindicator as claimed in claim 1, characterized in that the profile of the said endless screw includes at least an inclined section and at least a section perpendicular to the axis of the said screw.
Claim 4
Dependent Claim
35 words
A teleindicator as claimed in claim 1, characterized in that the said second means control the disactivation so the said electric motor during the interval of time in which the said transmission coupling is inactive.
Claim 5
Dependent Claim
29 words
A teleindicator as claimed in claim 1, comprising a front frame for the said indicator elements characterized in that the said front frame is extractable from the said teleindicator.
Claim 6
Dependent Claim
20 words
A teleindicator as claimed in claim 1, characterized in that the said indicator elements are of the type having plates.
Claim 7
Dependent Claim
15 words
An information board, characterized in comprising a plurality of teleindicators as claimed in claim 1.
Claim 8
Dependent Claim
63 words
A board as claimed in claim 6, in which the said teleindicators are disposed according to a plurality of lines and columns, characterized in comprising single first and second means for the teleindicators of the same column, the said first and second single means controlling the said third means of teleindicators of different lines, through enable means for enabling teleindicators of preselected lines.
