The improvements consist in that the sliding assembly (1) which comprises the movable carriage and the printing head (2) is mounted on a main straight guide (16) parallel to the printing media (6) with simultaneous lengthwise sliding capacity on said main guide as well as pivotation capacity on the same, until the adjustment value of the spacing (4) from the printing head (2) to the printing media (6) is obtained, by the intervention of abutment means to limit the pivotation of said sliding assembly. Said abutment means to limit the pivotation of the sliding assembly (1) are comprised of a second straight guide (11) parallel to the main sliding guide (16) on which second straight guide the sliding assembly is capable of abutting by means of an abutment portion. The sliding assembly (1) comprises two units (7), (8) connected by means of an articulated joint, the mutual position of both units being adjustable as to the angle or rotation, existing means for its locking in the desired position to determine a variable angle position between both units. <IMAGE> |
