When a contact detecting switchis turned on by a proximate ink cartridge CA, a personal computer PC identifies the proximate ink cartridge CA. The personal computer PC, in the event that the duration of sustained proximity of the proximate ink cartridge CA is longer than a predetermined time interval Tref, reads out the remaining quantity of ink from the memory device module M of the proximate ink cartridge CA and displays this on an external display device. In the event that the duration of sustained proximity is shorter than predetermined time interval Tref, the personal computer PC drives the carriageso as to move an ink cartridge CA installed on carriagecorresponding to the proximate ink cartridge CA to a replacement opening
