DEVICE FOR FLUID MEDIUM EJECTION Russian patent published in 2008 - IPC B41J2/05 

FIELD: technological processes; printing industry.

SUBSTANCE: device for ejection of fluid medium contains multiple activating cells, activation bus bar arranged with the possibility of energy signal reception and generator of address intended for formation of address signals sequence. Address generator contains shift register, which has double-stage cells designed for reception of input signal and storage of input signal, and logical elements that are intended for reception of input signals during every address time slot and formation of address signals sequence. Energy signal represents pulse of energy during every address time slot in sequence of address time slots for excitation of selected permitted activating cells. Unit of printing head is suggested that contains controller for generation of set of signals, in preset configuration, the first bus bar for passage of the first pulses, the second bus bar for passage of the second pulses, the first group of resistors and the second group of resistors, which are connected with the possibility to conduct on the basis of mentioned set of signals and pu;se signals.

EFFECT: device provides specific height of printing strip and makes it possible to retain costs.
