摘要： An actuator unit for an ink jet print head in which pressure generating chambers 30 and 31 are arranged in two linear arrays with a pitch P1 between the chambers in each linear array. The pressure generating chambers in one linear array are shifted by an amount equal to 1/4 of P1 with respect to the pressure generating chambers in the other linear array. A plurality of actuator units may be connected to a single flow path unit of the ink jet print head, and the nozzle openings in one actuator unit may be shifted by 1/2 of P1 with respect to the nozzle openings in another actuator unit, or they may be aligned. Various arrangements of the nozzle openings, the pressure generating chambers, and the actuator units can be employed to vary the resolution and to print different colors.

摘要： An ink jet printer head includes a spacer including pressure generating chambers continuous to nozzle openings, ink supply paths, and reservoirs, a cover member for covering the pressure generating chambers in a sealing fashion, and pressure generating means for generating pressure in the pressure generating chambers in accordance with print data. In processing a silicon single-crystal substrate vertically oriented in (110) by anisotropic etching process, one of the walls of a path hole for forming a pressure generating chamber is aligned with one of the walls of a path hole for forming a reservoir. Walls defining the path hole for forming a pressure generating chamber, which are located in the vicinity of a nozzle opening, are connected to each other at an obtuse angle. As a result, the ink supply path serving as a narrow path for ink flow and the pressure generating chamber are formed as smooth flow paths. The walls in an area in the vicinity of the nozzle opening where ink tends to stay are substantially equally distanced from the nozzle opening. A smooth flow of ink is ensured.

The actuator unit is prepared by laminating and fixing the first cover member, the spacer and the second cover member. A pitch at which the pressure generating chambers are arranged is set to a value equal to or smaller than a pitch at which the nozzle openings are arranged; widths of partition walls on outermost ends of pressure generating chambers located on the outermost ends are set to a value equal to or greater than a width of a partition wall defining adjacent pressure generating chambers and equal to or smaller than 1/2 of the nozzle opening arrangement pitch. An increase in the distance between the adjacent pressure generating chambers at the contact line between two actuator units is set to within a range of values substantially equal to the width of the partition wall.
