Abstract
The present invention relates to a piezoelectrically operated Braille transducer. The transducer comprises a supporting member, one portion of which forms a tactile reading surface and which houses members which are movable individually from a first position in which they are housed in the supporting member to a second position in which one end of the member projects from the reading surface in such a way that it can be detected by touch. For each of the movable members there is provided a piezoelectric operating member which acts on the corresponding movable member to make it move from the first position to the second position, or vice versa. The supporting member comprises a plate portion which supports the piezoelectric operating members and a block which supports the movable members and which forms the tactile reading surface. The aforesaid block is removably associated with the remaining part of the supporting member in such a way that it can easily be removed for maintenance or cleaning operations. <IMAGE>
