Abstract

PURPOSE:To provide a recorder capable of eliminating the undischarge of ink effectively with a simple construction by applying a higher voltage to a piezo- electric element than the printing voltage for a very shoft period based on the turning ON of a power source switch. CONSTITUTION:A signal generation circuit 16 of a head driving circuit 15 form a power source input signal a to be turned ON depending on the turning ON of the power source switch 11 while a power supply hold signal b to be inverted only by a very short time t1 synchronizing the turning ON of the signal a is formed. When a recovery output signal c is formed synchronizing the clock oscillation for the very short time t1 to apply a high voltage to a transistor T2 of the output circuit 17 through a resistance R7, a high recovery drive voltage by a voltage EO2 is applied to a piezo-electric element CP for the time t1.
