摘要： An ink jet type recording head composed of a plurality of head units and having a large number of nozzles without greatly increasing the width of the recording head. Outer walls 1a, 1b of a spacer 1 of the heat unit are inclined at an angle .theta. with respect to the arrangement lines A--A, B--B of pressure generating chambers 2, 3. A plurality of head units (e.g., 40, 41) are arranged so that end surfaces of the head units in the arrangement direction of the pressure generating chambers 2, 3 are adjacent to each other. The head units are fixed to a base board 28 such that they are shifted in a direction roughly perpendicular to the arrangement direction of then pressure generating chambers 2, 3 and so that an interval between the pressure generating chambers 2, 3 of the adjacent head units is the same as the pitch between the pressure generating chambers 2, 3 on each individual head unit. Accordingly, it is possible to arrange the nozzle openings of the plurality of head units at a uniform pitch even over several head units and nonetheless maintain the width of the entire recording head as narrow as possible.
摘要翻译：一种喷墨式记录头，由多个头单元组成并且具有大量喷嘴而不会大大增加记录头的宽度。加热单元的间隔件1的外壁1a，1b相对于压力发生室2,3的排列线AA，BB倾斜角度θ。多个头单元（例如，40,41）被布置使得压头发生室2,3的排列方向上的头单元的端面彼此相邻。头单元固定到基板28上，使得它们沿大致垂直于压力产生室2,3的排列方向的方向移动，并且使相邻头单元的压力产生室2,3之间的间隔与每个单独的头单元上的压力产生室2,3之间的间距相同。因此，可以将多个头单元的喷嘴开口均匀地设置在均匀的间距上，甚至在几个头单元上，并且仍然使整个记录头的宽度尽可能窄。

摘要： An on-demand type ink jet print head including a drive assembly formed from a vibrating plate formed of a piezoelectric layer with an electrode layer on one surface and an electrically conductive, physically resilient layer on the opposite surface of the piezoelectric layer. The vibrating plate is secured to a base and has two opposing edges defining a free space therebetween. The vibrating plate is slit into a plurality of strips and these strips are cross-slit in the widthwise direction to form a row of reed pieces secured to each opposing edge of the base in a cantilever configuration and extending into the free space from each edge toward the reed pieces extending from the opposite edge with a space therebetween. The reed pieces are electrically and mechanically independent of each other and have negligible electrical and mechanical interference with each other. Selective application of an electric field to the piezoelectric layer causes the reed pieces to deflect and jet ink from the print head onto a recording medium.

摘要： A nozzle surface (13) is sealed by a cap member (44) in a state in which an ink solution is accumulated in a sealed hollow portion (45). After the nozzle surface (13) is sealed, piezoelectric vibrators (35) are driven by applying thereto a high-frequency drive signal of a frequency higher than a drive frequency for ejecting the ink solution toward recording paper, thereby causing cavitation in the ink solution. The firmly adhering thickened ink and solidified ink occurring in nozzle openings (29) are broken or exfoliated by bubbles caused by this cavitation. Subsequently, the suction operation is performed to remove the thickened ink and the solidified ink from the nozzle portions.
