Abstract
A notch (recess portion) is proved on a front face of an ink cartridge, and a holding portion is set between a corner portion of the recess portion and a projection portion provided on a cartridge upper face. A cartridge can be held securely by nipping the cartridge between two fingers at both ends thereof (the projection portion and the corner portion) of the holding portion, even if the cartridge is a thin type cartridge, so that attaching/detaching of the cartridge to a printer main unit can be performed easily and securely.
