摘要： An ink-jet printer head is composed of individual, stacked ink-jet printer modules operating according to the edge-shooter principle and equipped with plate-shaped piezoelectric actuators whose electrodes are contacted to leads of a ribbon conductor. The ink-jet printer head has a simplified structure and improved service properties and is composed of individual, identical ink-jet printer modules whose nozzle rows are arranged offset relative to one another and can be easily interchanged, because the carrier layer of the ribbon conductors enveloping the leads is reinforced and shaped in the region between neighboring ink-jet printer modules, so that the required spacing between the piezoactuators and between the nozzle rows of the ink-jet printer modules as well as an exact fixing thereof relative to one another are achieved. In this way, the ribbon conductors serve as a contact element, a spacer and an adjustment member for neighboring ink-jet printer modules. Complicated housing and front masks are thus eliminated and the number of components is reduced and adjustment outlay is largely avoided. The ink-jet printer head is provided for use in small, fast printers, wherein a large number of nozzles are required.

摘要： An ink-jet printer head is composed of stacked ink printer modules operating according to the edge-shooter principle and each equipped with plate-shaped piezoelectric actuators. The ink-jet printer head is for use in small, fast printers, suitable for use in a franking machine wherein a large number of nozzles are required. Plate-shaped spacer parts between the ink printer modules are structured such that they serve both for assuring the required spacing between neighboring modules as well as for setting an offset of the nozzle apertures of the neighboring ink printer modules relative to one another. To that end, the spacer parts are provided with registration elements at both sides that engage into allocated recesses of the ink printer modules. Each ink printer module also has electrical interconnects for connection to a driver circuit. In order to suffice with only one connector array for connection to the driver circuit, interconnects are extended, for each module, from its outer diaphragm plate surface over the lateral surfaces of the module into its other outer diaphragm plate surface.

摘要： An ink printer head of individual ink printer modules operating according to the edge-shooter principle equipped with piezoelectric actuators is provided for use in printers for postage meter machines and correspondingly has a large number of nozzles arranged in columns. For this purpose, a nozzle module, composed of a nozzle plate and two adapter plates arranged at opposite sides thereof, is disposed between ink printer modules that are constructed mirror-symmetrically relative to one another and are equipped with piezoactuators applied on both sides. The adapter plates are provided with openings for ink guidance and with recesses providing for the free space needed for piezoactuators. The openings in the adapter plates are matched, first, to the nozzle dimensions and, second, to the dimensions of the connecting channels to the ink chambers and are aligned with both the nozzles and the connecting channels. Identical etching masks can be used for a number of plates due to the mirror-symmetrical structure. A reduction in the manufacturing outlay while preserving the requiring printing precision is achieved. A high degree of repetition is achieved by employing identical ink printer modules and ink paths of approximately identical length is also achieved. The nozzle apertures can be given a circular cross-section without difficulty.

摘要： In a method and apparatus for producing an ink jet printer head composed of a number of stacked modules, a piezoactuator plate is formed by metallizing opposite major faces of a plate of piezoelectric material, while leaving an unmetallized stripe on one of said major faces, thereby separating the metallization on that major face into two regions. A side face of the piezoelectric plate is also metallized, the side face extending substantially parallel to the unmetallized stripe, thereby electrically connecting one of the metallized regions on one major face to the metallized layer on the opposite major face. The metallized piezoelectric plate is then structured so as to produce a number of side-by-side piezoactuators therein, each piezoactuator having first and second electrodes formed by the respective metallization on the opposite sides of the plate. Respective electrical leads for the two electrodes of each piezoactuator can be electrically contacted to the same side of the plate, i.e. the side having the non-metallized stripe thereon.
