Abstract

PURPOSE:To compensate for dispersion in the driving efficiency of an ink jetting head, improve the maintenance of the head, and also reduce the cost of the head by providing a drive voltage regulator capable of adjusting the drive voltage of a piezo-oscillator to the ink jetting head. CONSTITUTION:In an ink jetting head 4 having a piezo-oscillator 5 and capable of jetting ink droplets by exciting the piezo-oscillator 5, a drive voltage regulator 2 to adjust the drive voltage of the piezo-oscillator 5 is provided. EFFECT:Maintenance cost is reduced, the control of the head is simplified, the control cost is also reduced. In the case of multi-head, these effects are further increased.
