Abstract:
This invention relates to a graphic tactile cell for indicating a graphic pattern, in which the arrangement of the tactile surface can be enlarged easily. This graphic tactile cell includes tactile pins for indicating a graphic pattern by vertical movement, piezoelectric element segments which are bent upon application of a voltage to vertically drive the tactile pins, and a unit base for holding the tactile pins and the piezoelectric element segments. A plurality of cell units each including a unit number of tactile pins, corresponding piezoelectric element segments, and a unit base for holding the tactile pins and the piezoelectric element segments are coupled vertically and horizontally such that the tactile pins are arranged at an equal interval in vertical and horizontal directions. Proximal ends of the piezoelectric element segments are held by the unit base through plastically deformable adjusting members.
