Abstract:
A portable apparatus to electromechanically emboss Braille patterns includes a user input, such as a six-key with spacebar keyboard, actuators that drive embossing pins via cam shafts coupled to servo or stepper motors, a tape advancing mechanism, and a cutter and scoring assembly. Three actuators, such as servo or stepper motors, may each be coupled to one shaft on which two or more cams drive two or more embossing pins for each row of two dots in the six dot Braille cell.
