Abstract
An ink jet recording device includes an external switch, a device for detecting the amount of ink left in each ink cartridge, and a device operating such that when an instruction to replace the ink cartridge is generated by the switch, or when a device detects an ink end of the cartridge, only the ink cartridge to be replaced is exposed through a window in the recording device. The ink cartridge to be replaced is specified, and only the specified ink cartridge is automatically moved to a replaceable position. Correct replacement of more than one ink cartridge is ensured, and the cartridge replacing work is simplified.
