摘要:
An electrically-assisted mechanical Braille writer includes a main solenoid to apply force to emboss Braille onto a printing medium, and advance an embossing mechanism to the next cell. A second solenoid engages a mechanical stop to prevent one or more embossing keys from being fully depressed, to prevent kickback from the keys mechanically coupling to the main solenoid. In unpowered operation, the mechanical stop is disengaged, and the embossing keys may be fully depressed to apply force to emboss Braille and advance the embossing mechanism. Accordingly, with electrical power, the user may supply a lesser amount of force and still fully emboss Braille cells, while without electrical power, the Braille writer remains fully operational.
