ABSTRACT:
A typewriter for Braille and printed characters including Braille character typing symbols, printed character typing symbols and a transferring member used to move both of the Braille character typing symbols and the printed character typing symbols horizontally along a recording medium. The Braille character typing symbols are actuated by solenoids whereas the printed character typing symbols are formed by a dot printer both of which are simultaneously transferred by a stepping motor. The Braille character typing symbols are disposed at opposite sides of the printed character typing symbols beneath a casing for positioning a recording medium, i.e., typing paper. Therefore, printed character symbols will appear on one side of the recording medium whereas Braille character will be embossed on the other side of the same recording medium. Thus, both a blind individual and an individual with normal vision may obtain the same recorded information which appears on the same recording medium.
