Problems solved by technology
However, since the fixing mechanism may resist the urging force of the coil spring by abutting against the surface of the ink cartridge, a load is exerted on the surface of the ink cartridge, thereby causing damage to the ink cartridge unless the strength of the ink cartridge itself is increased to some extent

An ink cartridge includes an ink storage chamber for storing ink provided therein. The ink cartridge is mountable to an inkjet recording apparatus. The inkjet recording apparatus includes: a door disposed on of an accommodating chamber defining a space for accommodating the ink cartridge and allowing the ink cartridge to be mounted thereto in the horizontal direction through a first opening and configured to be rotated about the lower side of the accommodating chamber as an axis of rotation for opening and closing the first opening and closing the first opening when it takes an upright posture; and a pressing member provided on the door for pressing a back surface of the ink cartridge inserted into the accommodating chamber by a resilient force. The ink cartridge comprising: (a) an ink supply part provided on a front side surface being defined in a mounting direction when the ink cartridge is in a mounted posture, which is a posture when the ink cartridge is mounted to the accommodating chamber, and having a second opening for allowing entering of an extracting member of the inkjet recording apparatus when being mounted to the inkjet recording apparatus; (b) a supply valve mechanism for opening and closing the second opening of the ink supply part; and (c) a pressed portion provided on a back surface at the rear side in the mounting direction when the ink cartridge is in the mounting posture and configured to be pressed by the pressing member. The supply valve mechanism includes a supply valve member for opening and closing the second opening of the ink supply part and a supply urging member for urging the supply valve member to a direction of closing the second opening of the ink supply part. The urging force of the supply urging member is adapted to be smaller than the resilient force of the pressing member for pressing the pressed portion.
Description
technical field [0001] The present invention relates to an ink cartridge and an inkjet recording apparatus, and more particularly, to an ink cartridge and an inkjet recording apparatus capable of stably maintaining the mounted state of the mounted ink cartridge and preventing damage to the ink cartridge. Background technique [0002] As disclosed in Japanese Patent Laid-Open No. 2003-25608, there is an inkjet printer in which a plurality of ink containers are inserted and mounted in the horizontal direction. A tower-shaped ink outlet is formed on a front end side surface of the ink container along an insertion direction, and a fluid inlet corresponding to the tower-shaped ink outlet is formed on a corresponding side surface of the inkjet printer so as to protrude toward the ink container. When the ink container is inserted and installed in a predetermined position in the inkjet printer in the horizontal direction, the tower-shaped ink outlet and the fluid inlet are connected...
