Abstract
A carriage on which an ink tank is mounted is moved acceleratively. Next, under this accelerative movement, a period of time spent moving a designated distance is measured. Finally, the amount of ink fluids in the ink tank is detected by the measured period of time and a message related to the amount of ink fluids is displayed. With these procedures, in an ink jet recording apparatus in which the ink tank for storing ink fluids to be supplied to the recording head is mounted on the carriage, the amount of ink fluids remaining in the ink tank can be detected using simplified structure.
