Abstract
A Braille mouse uses a character-code carrying member such as a disc, belt or drum to selectively raise Braille pins with a single solenoid. The Braille pins are provided with eccentric fingers which interact with a character-code carrying member, so that the character codes can be arranged in straight radial lines to allow all possible six-pin Braille symbols to be provided on a member of minimum size.
