Abstract: A braille graphics cell module includes a unit substrate, a braille graphics display section which holds a plurality of tactile pins movably in a vertical direction to display braille graphics, a plurality of piezoelectric element pieces, which move the corresponding tactile pins in the vertical direction at a free end thereof by bending action, arranged on a surface of the unit substrate in association with the plurality of tactile pins, and a wiring part arranged at a lower end of the unit substrate so that an upper edge of the wiring part is located close to a node portion of each piezoelectric element piece for a bending operation and a lower edge thereof is located close to the fixed end of the piezoelectric element piece, and having an electric circuit in which the fixed ends of the plurality of piezoelectric element pieces are electrically connected to the wiring part.

Abstract: A braille label writer for inscribing braille on a labeling tape, according to the invention, comprises an operating section provided with operation keys including an input key, a memory for storing information concerning letter codes and braille codes, a display section for displaying information including letters, converting means for converting a letter code into a braille code, and an inscribing section for inscribing braille corresponding to the converted braille code. The inscribing section includes a plurality of solenoids having plungers, levers provided for the respective solenoids for transmitting driving forces of the plungers of the solenoids, and push pins for forming raised braille characters on the labeling tape. The plungers are arranged parallel to the push pins.

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.
