    摘要: A head drive of an inkjet printer includes nozzles and corresponding actuators that eject liquid ink drops. A drive unit applies a drive signal to the actuators. The drive unit includes a drive waveform generator that generates a drive waveform signal to control the drive of the actuators. A modulator pulse modulates the drive waveform. A digital power amplifier amplifies power of the modulated signal. A low pass filter smoothes the amplified digital signal and supplies the signal as a drive signal to the actuators. An inverse filter provided in a subsequent stage of the drive waveform generator corrects at least the frequency characteristics of the filter to predetermined frequency characteristics, independent of the number of the actuators to drive.

    摘要: With an appropriate signal transmission form, a drive pulse output circuit is mounted to an ink jet head, so that waveform distortion of an actuator drive pulse for jet of ink drops is inhibited or prevented. Modulated signal data in memory is read to output a modulated signal, which is power-amplified by a digital power amplifier. The amplified digital signal is smoothed to be output to an actuator as a drive pulse. As a result, the digital power amplifier having high amplification efficiency efficiently amplifies the power of the modulated signal, thereby eliminating the need to use a cooling unit. The drive pulse output circuit can be mounted to the ink jet heads, thereby shortening the transmission path of an actuator drive pulse, which inhibits or prevents any waveform distortion of the drive pulse. The transmission of the modulated signal data DATA is implemented with a low frequency.
