Abstract
The multicolor thermal printer comprises a frame (1), a platen (4) and a carriage (2) that can move along the platen (4). This carriage (2) consists of a lower part (5) carrying the thermal print head (3) and an upper part (6) hinged to the part (5) thanks to a hinge pin (7a). The upper part (6) carries four inking ribbons (31) located on levels of height increasing from the front to the rear so that the inking ribbons are arranged in a vertically offset fashion on the ribbon guides (40). By pivoting of the upper part (5), the ribbons can be placed successively opposite the heating elements (3a). A drive mechanism (53 to 68) for the ribbons is made so as to drive only the ribbon placed opposite the heating elements (3a) and only when the carriage (2) is moved in the direction of printing. By this design, a fast change of the printing color and a reduced consumption of inking ribbons can be attained.
