Abstract

PURPOSE: To establish the small size and light weight unit less in power consumption, by combining the head drive circuit driving the ink jet head, boosting circuit and control circuit for recorder, and taking the control circuit with C-MOS or ILL logic elements.
CONSTITUTION: The head drive circuit 4 driving the recorder head 5 of ink-on- demand type used the piezoelectric element for the drive source as the electromechanical conversion element, and the boosting circuit 3 supplying sufficient power to operate the piezoelectric element are provided. Further, the input data is processed, memory unit control circuit 1 to form required information to the drive circuit 4 and the head 5 is provided, and battery 2 is connected to the boosting circuit 3 to constitute the portable recorder. This boosting circuit 3 is added with the temperature compensation circuit to compensate the operation due to temperature change in the piezoelectric element, and the control circuit 1 is composed of C- MOS or ILL, thereby constituting the unit with small size and light weight suitable for portable type, together with power reduction.
