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.
