发明名称 Stylus for writing braille
摘要 A stylus for writing braille by hand is provided. The stylus has a longitudinally extending handle, an arm attached to the handle with an angularly offset, pointed end for making braille impressions in paper, and a pressure pad attached to the arm for supporting a user's finger. The handle is specially configured to locate the user's hand to a uniform gripping position during use of the stylus while the pad acts in conjunction with the user's index finger for applying downward pressure on the pointed end of the stylus.
