Abstract
A printer with a print-head distance-setting device for adjusting the distance (1) between print head (2) and print-material counter support (3) for recording-material carriers (4) of unequal thickness, resting on the print-material counter support (3), including a mechanical sensing member (5) for controlling a print head (2), adjustable in a direction perpendicular relative to the longitudinal direction of the slider carriage motion, where the print head (2) is disposed on a longitudinally movable print-head slider carriage (7), which print-head slider carriage (7) in turn is guided with a pair of parallel guide axles (9), of which one guide axle (9) is supported by way of a pair of eccentric-disposed pins (10) and of which the second guide axle (9) is cross-movably supported in the printer side walls (32). In order to achieve a simpler and more easily constructed print-head distance-setting device, which can in addition be controlled more accurately, an electrical analog signal, generatable by the setting motions of the sensing member (5), serves in a converted configuration of an electronic digital signal in an electronic circuit (11) for the control of a step motor (12), supported at a printer frame, where the step motor (12) forms a servo drive (13) for the pair of eccentric-disposed pins (10) of the guide axle (9).
