Title: Ink-jet head-driving apparatus
Inventor: KOYAMA TAKAHIRO
IPC: B41J2/015
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To print a halftone of many levels in a wide range by setting an ultrasonic wave generation means, a converging means, and a means for controlling a gate count in a set timing and a pulse count in a predetermined gate width to conform to a discharge amount with the use of a high frequency pulse array. SOLUTION: An ink-jet head is constituted of a vibrator 6 for generating ultrasonic waves, an ultrasonic wave-converging means 102 for converging the ultrasonic waves generated by the vibrator 6 in the vicinity of a liquid level of an ink, and a nozzle 105. The vibrator 6 vibrates in a thicknesswise direction for only a time when burst signals 4-1 as a driving signal group are applied. The ultrasonic waves generated consequent to the vibration are propagated in an ink chamber 104, diffracted by the ultrasonic-converging means 102 and converged to a convergent point 107 in the ink chamber 104. The ultrasonic waves generate a pressure at the convergent point 107, whereby drops of the atomized ink are discharged from the point. A host computer 1 is a controller for a driving device, and a control device 2 controls the ink-jet head.
