INK JET PRINTER

摘要

The ink jet printer includes a print head (1) with pressure chambers (17), each pressure chamber being formed as a recess in an actuator plate (9) which is bonded by two main faces and a number of side faces, said recess communicating on the one side with an ink supply device (29) and on the other side with a nozzle (25). The nozzles (25) are arranged in a matrix. In the actuator plate (9) there are formed actuator elements (15) which are positioned relative to the pressure chambers (17) in such a manner that, each time a voltage is applied to an actuator element, that actuator element can cooperate with one of the pressure chambers in order to change the volume of the respective pressure chamber. In order to reduce the distance between the nozzles (25), each nozzle opens into a face which coincides with or extends parallel to a first side face (19) of the actuator plate (9) and at least two actuator plates are stacked in such a manner that a block-shaped member (39) is formed and their first side faces form part of a first face of the block-shaped member.
