Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a structure for fixing an ink cartridge to a head holder and removing the ink cartridge therefrom easily and for holding the ink cartridge surely. SOLUTION: An ink cartridge 20 containing ink and having an ink supply opening on the bottom is held removably on a head holder 10 opening upward with a coupling part being fitted to the ink supply opening projecting from the bottom thereof. In such an ink cartridge holding structure, first stopping parts 23 are provided on the opposite side walls of the ink cartridge 20 and resilient pieces 15 are provided in the head holder 10 oppositely to the side wall of the ink cartridge 20 provided with the first stopping parts 23. The resilient piece 15 is provided with a second stopping part 16 being engaged with the first stopping part 23 upon finishing insertion while allowing the ink cartridge 20 to descend down into the head holder 10 through elastic deformation. |
