ABSTRACT:
A printing device such as a typewriter and the like, comprising a printing unit with a positioning manipulator, an impacting unit, and a supporting surface. The printing unit is provided with a cassette in which a plurality of card-like printing elements are located. Each printing element has a plurality of vertical rows of printing characters and a plurality of horizontal rows of printing characters. A vertically mechanically reciprocated manipulator latches on to a selected printing element and raises it to bring the horizontal row containing a selected character to the height of the printing station. The selected printing body is moved laterally in its plane to bring the selected printing character into line with the printing station. Moving or positioning of the printing elements is achieved by means of linear-step electric motors.
