摘要： A driving device for a piezoelectric element is provided which attains lower power consumption, low heat generation and low cost. To displace a piezoelectric element, a first switching transistor is rendered ON by a control circuit. The electric charges flow in the piezoelectric element from the power supply through the first switching transistor. This state is continued until a sufficient amount of electric charges are stored in the piezoelectric element. To restore the piezoelectric element thus displaced, a second switching transistor is rendered ON under the condition where the first switching transistor is OFF. In this condition, a resonance circuit is formed by the piezoelectric element and the coil. When the electric charges are flowing in the coil and a predetermined period of time has elapsed after the second switching transistor is rendered ON, the control circuit renders the second switching transistor OFF, whereby the current flowing in the coil flows into the power supply.

摘要： A dot printing apparatus in which the piezoelectric print head having the piezoelectric element connected to the printing wire is utilized and the secondary bounce of the printing wire is effectively controlled according to one of three dot printing modes (the normal continuous dot printing mode, the last dot printing mode in the continuous dot printing mode and the single dot printing mode), is disclosed. The dot is judged every time the dot printing is performed. And if judged the normal dot printing mode, the discharging of the piezoelectric element is conducted relatively fast after the dot printing in the present printing pitch is performed to charge the piezoelectric element, since the dot printing data exists in one or more printing pitches both before and after the present printing pitch, thus, the dot printing in printing pitch next to the present printing pitch is performed. And if judged the last dot printing mode, the electric energy stored in the piezoelectric element is partially removed at the first timing according to the discharging pulse with relatively narrow width, thereafter, the remained electric energy is completely removed. And further, if judged the single dot printing mode, the electric energy stored in the piezoelectric element is partially removed at the second timing later than the first timing according to the discharging pulse with the width wider than that in the last dot printing mode, thereafter, the remained electric energy is completely removed.
