The Perkins Brailler

It is a typewriter with a key corresponding to each of the six Braille code.A back space key, a space key and a back line space key like a manual typewriter.
The two sides knobs are to advance paper through the machine and carriage return lever above key.The rollers that hold advanced paper have grooves to avoid crushing the raised dots that Brailler creatses .Unfortunately the center can not provide smart Braillers .
