Abstract: A temperature characteristic correction device corrects a temperature characteristic of an electronic device. The temperature characteristic correction device calculates a peak correction characteristic approximating a peak waveform having a peak value in a second range included in a first range of the temperature characteristic using a first formula, and a correction characteristic approximating a waveform continuing in the first range of the temperature characteristic using a second formula. The temperature characteristic correction device calculates a total correction amount from the peak correction characteristic and the correction characteristic, and then corrects the temperature characteristic using the total correction amount.

Abstract: A liquid storage unit for collecting a liquid supplied to an ejecting head is provided. The liquid is supplied to a plurality of ejecting heads via a pressure regulating valve, and the liquid is suctioned from the plurality of ejecting heads by a circulation pump, and then is discharged to the liquid storage unit. In this way, since the liquid is suctioned from each of the ejecting heads, the passage resistance is decreased, so that the ink can be appropriately circulated. In addition, since the ejecting head is supplied with the liquid at an appropriate pressure from the liquid storage unit via the pressure adjusting valve, the liquid can be appropriately ejected.
