    摘要: A bonding width L between a head frame 5 and a flow path unit 12 in a direction orthogonal to an array of pressure producing chambers 7 is set to 0.5b.ltoreq.L.ltoreq.5a if it is assumed that a distance from the bonding end to the piezoelectric vibration element 2 closest to the head frame 5 is a and that the bonding ends of the head frame 5 interposing the piezoelectric vibration element 2 is b. Cracking of a spacer 6 or separation of the spacer 6 from a resilient plate 4 is prevented by ensuring a rigidity of the head frame 5 necessary for suppressing deformation of the flow path unit 12 and by causing the head frame 5 to absorb internal stresses of the flow path unit 12 caused by ambient temperature change.

    摘要: An ink jet printing device supplies first and second signals to cause a pressure generating chamber to jet out ink droplets. A third signal is applied to the pressure generating chamber to effectively attenuate the kinetic energy of the meniscus and to hold the meniscus at a position suitable for jetting out the next ink droplet to provide a stable print output. Also, an ink-jet recording apparatus is provided with a control means for controlling the timing of the start of the second signal and the timing of the start of the third signal according to the environmental temperature. In the ink-jet recording apparatus, the discharge speed of ink drops is made constant by regulating the start time of the second signal so as to make constant the drawing position of a meniscus when the ink drops are discharged. Further, the pressure generating chamber is expanded again by applying the third signal at the time the vibration of the meniscus generated by the discharge of the ink drops is moved closest to the pressure generating chamber, so that the kinetic energy of the meniscus moving to the nozzle can effectively be attenuated.

    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.
