Abstract

PURPOSE:To enable stable injection of ink removing suprious by specifying a relationship between the length of a pressure chamber and the length of a conduction path. CONSTITUTION:A voltage is applied to a piezo-electric element to generate a distortion by which ink in a pressure chamber 8 is pressured and injected through a nozzle 9. In this case, the length lp of the pressure chamber and the length lg of a conduction path 10 meet the relationship as given by the equation.
