Abstract

PURPOSE:To easily remove noise trouble, miniaturize an ink jet head device, and reduce the cost of the ink jet head device by providing a piezo-electric driving element to the ink jet head. CONSTITUTION:A low voltage control signal to be put in a terminal 1 is amplified by a switching element 2 into a high-tension pulse and then sent out of a terminal 4. A terminal 3 is a power source terminal to which power is supplied from a high-tension power source. A resistance element 6 serves to prevent the flow of overcurrent to the switching element 2 when the switching element 2 changes from OFF-state to ON-state, because a piezo-electric driving element 8 is intrinsically capacitive, and also a resistance element 5 serves to discharge charge stored in the piezo-electric driving element 8. Thus, in the ink jet head having a structure in which the piezo-electric driving element is additionally provided, a conductive material of high-tension pulse can be limited to the power source supply line and a low-voltage control signal can be directly put in the ink jet head. And the number of the low-voltage control signal line can be reduced according to the number of the piezo-electric driving elements.
