Abstract
A liquid injection recording apparatus which discharges liquid droplets by the contraction or expansion of a piezo-electric element and effects recording by the use of the discharged liquid droplets is provided with a wave form shaping circuit for shaping the wave form of a signal applied to the piezo-electric element, and a converting circuit for impedance-converting the wave form shaped circuit. The converted signal is applied to the piezo-electric element.
