摘要： A capacitive load driving unit includes a plurality of capacitive loads, a drive circuit for charging and discharging the capacitive loads, a pair of power lines for supplying a drive voltage from an external power source to the drive circuit, and a current reserve circuit for reserving a current required by the drive circuit for charging the capacitive loads. The current reserve circuit includes a capacitor that is charged by the drive voltage from the power lines, and a coupler section for coupling the capacitor between the power lines except for when a defect inspection is conducted.

摘要： A data converting circuit to receive an input data and convert the input data into an output data is disclosed. An output data group corresponding to the value of the input data is stored beforehand in an output data table. A multiplexer receives the input data and in accordance with the input data, selectively outputs one data out of the output data group stored in the output data table. A specific digit output circuit receives the input data and in accordance with the result of comparing the input data with the boundary information stored in advance, outputs a specific digit output data included in the output data but not output by the multiplexer.
