Liquid jet apparatus and method for driving the same |
摘要 |
A driving signal generation unit generates a plurality of kinds of driving pulses and a minute vibration pulse to be applied to a pressure generation element so as to finely vibrate a meniscus of liquid. A pulse generation unit generates the minute vibration pulse and the driving pulses by selecting a part of the driving signal. The driving signal includes a plurality of waveform elements used to generate the driving pulses and a connection element used to connect the waveform elements between different voltage levels and not used to generate the driving pulses. The pulse generation unit generates the minute vibration pulse by a combination of at least a part of the waveform elements and at least a part of the connection element. A plurality of driving pulses for ejecting a plurality of kinds of ink drops and a minute vibration pulse for causing minute vibrations to a meniscus of liquid can be efficiently put in a driving signal of one driving period.
