Findings

Design enables quick embossing of Braille characters by column.

The system reduces complexity and cost of Braille embossers.

Potential for more accessible Braille printing solutions.

Abstract

This paper presents the conceptual design of a low-cost simple printer head for Braille embossers. Such device consists of a set of three rotary cam-follower mechanisms that, upon actuation, produce deformation on paper. The set of cam-followers is actuated by a single servomotor which rotation determines which cam-follower strikes the paper. Braille characters are quickly embossed by column using the proposed system. The aim of this research is to provide new actuation ideas for making Braille embossers more affordable.
