Abstract
A device for printing in the Braille system. The device includes a magnetic core with an outer layer on the core provided with holes arranged in a pattern for composing a text to be printed. Pins of magnetizable material are adapted to be inserted in the holes. The pins are of a greater length than the thickness of the layer. They are adapted upon contact with the magnetizable core to be attracted thereto to be retained in the holes. The core forms a roller and includes two end portions between which is a depression. An electrical winding is provided in this depression to magnetize the core. The outer layer is of a non-magnetizable material. The core includes a layer of magnetizable material inside of the outer layer to cover the holes therein.
