| Summary: | A circuit for driving a liquid drop spraying apparatus capable of smoothly supplying liquid to a pressurizing chamber is provided. A coil is provided in series with respect to a resistor that determines the charge characteristics of a charge circuit of a piezoelectric/electrostrictive element, thereby enabling gentle start characteristics when a charge voltage rises. In addition, discharge circuits are provided at two stages. A constant of the second discharging circuit is set to be smaller than a constant of the first discharging circuit. Coils are provided in series with resistors that determine their discharge characteristics. In this manner, even in the case where a large amount of liquid is sprayed, liquid is smoothly supplied to the pressurizing chamber. |
