Abstract
For generating individual droplets, an arrangement for an ink printer device comprises conductor loops as drive elements, the middle parts thereof lying in a common ink chamber and being movable therein under the influence of a magnetic field dependent on a change of current flux through a conductor loop; the conductor loops are fashioned of webs in a terminating plate, these webs being separated by columns having capillary action; every movable middle part includes a breach which forms a discharge opening; the terminating plate combines the function of the drive elements, of the nozzle plate and of an ink tight cover of the ink printer device.
