Liquid-jetting device

A liquid ejection apparatus comprising:

• a liquid ejection head for ejecting liquid toward a target, a liquid cartridge for storing said liquid, a liquid passage for connecting said liquid injection head and said liquid cartridge, and a cartridge holder for housing said liquid cartridge, said cartridge holder including:
• a slide member slidable along an insertion direction of said liquid cartridge between a first slide position and a second slide position, with the insertion direction being a direction in which the liquid cartridge is inserted into the cartridge holder when the liquid cartridge is attached to the cartridge holder;
• a lock claw member supported at said slide member rotatably between a first rotation position and a second rotation position;
• and
• a rib abutting said lock claw member,
• said rib causing said lock claw member to be located at the first rotation position when said slide member is located at said first slide position, and causing said lock claw member to be located at the second rotation position when said slide member is located at said second slide position, and
• said liquid cartridge including an engaging portion switching between a state in which the engaging portion is engaged with said lock claw member and a state in which the engaging portion is not engaged with said lock claw member, wherein said engaging portion is not engaged with said lock claw member when said lock claw member is located at said first rotation position, and is engaged with said lock claw member when said lock claw member is located at said second rotation position.
