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： An ink supply communication path is formed so that one end thereof is arranged outside a region confronting a pressure producing chamber at a region confronting a reservoir chamber; and an ink supply constricted port is arranged at a portion of the ink supply communication path, the portion being remotest from the pressure producing chamber. Since the pressure producing chamber is connected to the ink supply constricted port through the elongated ink supply communication path, a jet flow from the ink supply constricted port grows into a large flow along the ink supply communication path, which in turn allows air bubbles susceptible to stagnation in the vicinity of the ink supply constricted port to be discharged by such large flow.

摘要： While a pressure producing chamber is largely expanded before jetting ink droplets so as to increase an amount capable of capturing meniscus, distances of d1, d2, and d3 defined from the meniscus produced when the ink droplets are jetted up to a tip portion of a nozzle opening are arbitrarily varied in order to adjust the weights of the ink droplets. As a result, the ink amount of the ink droplets can be reduced which are jetted from an ink jet type recording head in which a piezoelectric vibrating element is employed as a pressure producing source.
