Abstract
The paper describes the problem of a multiline Braille display construction design. The bipolar two-phase step motors with planetary gear box and helical gear are used as actuators. Unlike widely used analogues, the mechanism model has a remarkable constructive feature, providing the use of a smaller number of actuators than the number of actuated Braille dots. It is achieved by means of fixing each dot in certain position by a mechanical element (fixator). Even if power supply is interrupted, the information displayed does not disappear. The actuators require power supply only when changing the dot state, that gives the possibility to reduce electricity consumption. The proposed display model differs from the existing ones by the ability to display more than one line simultaneously (any given number of lines). The page is updated line by line. At this, each dot is fixed mechanically due to the use of multi-channel communication system. Three-dimensional model of the multi-line Braille display is designed.
