Abstract
A recording apparatus for recording by discharging plural kinds of ink from the recording head to a recording medium comprises detection device for detecting the decrease of ink remains of each ink of the plural kinds of ink, ink amount indication device arranged in a number smaller than the number of the plural kinds of ink, and signal outputting device for outputting signals which enables the decrease of ink remains having the least amount of ink remains to be displayed on the ink amount indication device in accordance with the results of plural detections by the detection device. In this way, only the ink remains having the least ink remains among those kinds of ink in use is indicated on the display, not the ink remains of all the kinds of ink, thus making it possible to minimize the number of indication devices to make the indication device simpler and smaller or minimize the area on the screen of the display assigned for indicating the ink remains in order to save it for indicating more information other than the ink remains.
