发明名称 DRIVE CIRCUIT FOR INKJET RECORDING HEAD, AND INKJET RECORDING DEVICE
摘要 A drive circuit for an inkjet recording head includes a plurality of electrically capacitive actuator elements, a drive signal source, a plurality of switching elements, and a plurality of resistances. The actuator elements are provided for a plurality of nozzles, and drive the nozzles to eject ink therefrom. The drive signal source outputs a drive signal for driving the actuator elements. The switching elements are connected to the respective actuator elements to separately drive the actuator elements, and selectively apply the output drive signal to the actuator elements. The resistances are provided for the respective actuator elements, and are connected to low potential sides of the actuator elements. Each of the resistances has a resistance value adjusted in accordance with the length of a wire between the corresponding one of the actuator elements and the drive signal source.
