Braille writing device

A braille writing device, to form tactile dots onto an embossing medium, comprising:

• a. a hollow base structure, open from the top, and graspable by a person's one or two hands, further comprising:
• i. a tape exit port,
• ii. a cutting edge, and
• iii. a top receiving region for a tape handling structure,
• b. the tape handling structure, attached to the base structure's top receiving region, with a planar top region and a downward protruding structure, further comprising:
• i. an embossing anvil on the top planar region, with six concave features arranged in a two-by-three grid,
• ii. pairs of coaxial grooves for accepting cylindrical axles,
• iii. a projecting tape reel axle holding structure which protrudes horizontally from the downward structure, and
• iv. alignment and attachment structures on the planar top region's upper and lower surfaces to guide and connect with the base structure and embossing arms,
• c. a ring embossing arm structure with a planar ring structure to which are attached the embossing arms projecting radially inwards, each of the embossing arms having a flexural hinge member and each of the embossing arms tapering to a convex tip, where the convex tips of the embossing arms form at least three rows of two, further comprising:
• i. the convex tips aligned with the embossing anvil, and
• ii. alignment and attachment features on the planar ring structure's upper and lower surfaces to guide and connect with the base structure below and a top cap above,
• d. the top cap, open on the bottom, the top cap mating with the ring embossing arm structure, with six flexural button arms pointing inwardly, further comprising:
• i. a downward column attached at the distal end of each button arm to transfer forces respectively from the flexural button arms to the embossing arms, and
• ii. a downward facing receiving region for connecting to the ring embossing arm structure, the receiving region including alignment and attachment features.
