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.

Abstract: This invention discloses a tactile reading device including sensing rods that are supported to be vertically movable, piezo-electric actuating elements disposed in the vertical direction such that their free end portions are directed upward, and pushing-up cams having first levers which are axially and pivotally supported on support rods provided at an upper position of the free end portions of the piezo-electric actuating elements, extending downward from the support rods, and having side surfaces at distal end portions thereof which are freely abutted against the free end portions of the piezo-electric actuating elements, and second levers extending horizontally from the support rods and freely mounting, on their mounting planes, lower end portions of the sensing rods corresponding to the piezo-electric actuating elements.

Abstract: The present invention relates to a Braille reading display terminal device in which a non-intelligence-type Braille reading input/output unit is connected to a host computer through an expansion bus, an expansion bus interface is interposed between the input/output sections of the Braille reading input/output unit and the expansion bus, and unit input/output elements of the input/output sections sections are accessed or controlled through the expansion bus based on software in the host computer.

Abstract: The present invention discloses a braille cell comprising plural piezoelectric element reeds which are bent at the free ends thereof when DC voltage is added to them, a base body to which the piezoelectric element reeds are fixed at the base ends thereof through a print circuit board and which supports the piezoelectric element reeds piled like steps at a certain interval, and tactile pins provided corresponding to the free ends of the piezoelectric element reeds, wherein a tactile section for holding the tactile pins and provided with a detachably attaching means is detachably attached to the base body and wherein fixing plates are attached to both sides of the base body by means of their detachable attachment which is to define the piezoelectric element reeds in left and right directions of the base body.
