Abstract
A fluid spraying head (1) for an ink jet printing device includes a plurality of drop generating elements which are connected to flexible ducts, which in turn are connected to fluid jet nozzles. The fluid jet nozzles are displaceably arranged in respective slots of first and second guiding members (5, 7). The height or size of printing patterns generated by the fluid spraying head onto an object which is moved relative to the fluid spraying head can be varied by changing the relative position of the first and second guiding member (5, 7) with respect to each other.
Claims5
Fluid spraying head (1), for an ink jet printer adapted for ink jet printing of characters or information patterns of variable height onto an object movable relative to said head (1),
- said head (1) including a plurality of drop generating elements and a plurality of nozzles (4a-4g),
- characterized in that
- said head (1) comprises a plurality of flexible ducts (3a-3g) connected at one end thereof to respective said drop generating elements of said head (1) and connected at the other end thereof to respective said nozzles (4a-4g);
- that said nozzles (4a-4g) are displaceably arranged in first slot means (6) of a first guiding member (5) adapted for guiding said nozzles (4a-4g) in a first direction essentially perpendicular to the direction of relative movement of the object with respect to said head (1);
- that each said nozzle (4a-4g) is further displaceably arranged in a respective slot (8a-8g) of a group of second slots (8a-8g) of a second guiding member (7);
- that said second guiding member (7) is movable in a direction essentially perpendicular to said first direction;
- and
- that the respective directions of extension of said second slots (8a-8g) are angularly offset with respect to each other.
