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. a 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. protruding horizontally from said downward structure, a projecting tape reel axle holding structure,
• iv. alignment and attachment structures on said 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 embossing arms projecting radially inwards, each with a flexural hinge member, tapering to a tip, where the convex tips on the arms form three rows of two, further comprising:
• i. tips aligned with the embossing anvil
• ii. alignment and attachment features on said planar ring structure's upper and lower surfaces to guide and connect with the base structure below and a top cap above,
• d. a top cap, open on the bottom, which mates with said ring embossing arm structure, with six flexural button arms pointing inwardly, accessible by a person's fingers while grasping said base structure, further comprising:
• i. a downward column attached at the distal end of each button arm to transfer forces respectively from said flexural button arms to said embossing arms
• ii. a downward facing receiving region for connecting to said ring embossing arm structure, said receiving region including alignment and attachment features, and
• e. a ratchet drum with notches equally spaced about the circumference of the drum and a tape guiding roller surface located in the center, with protruding cylindrical axles which rotate in one of the tape handling structure's coaxial groove pairs,
• f. a pawl engaging the ratchet drum,
• g. one or more cylindrical tape guiding roller(s) with cylindrical guides for the tape, and with protruding cylindrical axles which rotate in the tape handling structure's coaxial groove pairs.
