Abstract: The invention relates to an apparatus for producing elevations which can be detected in a tactile manner on a flat recording medium, with the following components: at least one stamp with several printing areas which are provided with one or several elevations; at least one printing plate with several recesses; a drive device to move the stamp in a recording direction along the recording medium; an adjusting device to adjust the stamp so as to bring a printing area to a printing position in which the elevations of the respective printing area are opposite of the recesses of the printing plate and a printing device to press the stamp against the printing plate in order to form one or several recesses on the interposed recording medium which correspond to elevations on the opposite side.

Abstract: An apparatus for conveying information includes a perforated plate having a plurality of circular openings; at least one pin (5, 15, 25, 25, 35, 45, 55, 65, 75, 85) which is axially movable to project through and above a respective circular opening, an electromagnetic actuator (6, 16, 66, 116) for moving the pin (5, 15, 25, 25, 35, 45, 55, 65, 75, 85), and a permanent magnet for retaining the pin in at least two stable positions.
