Abstract

A reading plate has an array of holes in its surface. Rounded ends of rods project selectively through these holes by the action of a set of bimorphous piezoelectric reeds, to which they are coupled. Each reed is connected to a source of voltage which can assume two distinct values as a function of an electrical control signal in order to make the piezoelectric reeds bend in one direction or the other. The rods are distributed in groups of six and arranged in each group according to the conventional arrangement of dots of a Braille character. The transducer can thus provide a relief read-out panel for a pocket electronic calculator for the blind. Methods of using these transducers for recording and readout of magnetic tape with data in Braille-generable form and equipment incorporating them are disclosed. <IMAGE>
