Abstract: A recording apparatus which can prevent a drop of a recording head upon attachment of the recording head to a carriage is provided. When a head cartridge is attached/removed to/from a carriage, the carriage is moved to an overlapping position with a head supporting base and stopped there. Projection supporting portions to guide and support rough guide projections on both side surfaces of the head cartridge so as to be properly received to guides provided for the carriage are provided for the head supporting base.

Abstract: In an ink-jet printer of the present invention, an ink circulation path 4 is formed by an ink head 2, a first tank 31, a second tank 32, and a pump 33. The ink-jet printer switches between an ink-circulation state and a no ink-circulation state during a printing operation, and is capable of performing printing in either of the states.

Abstract: A liquid ejection apparatus includes liquid cartridges, each of which includes a liquid container and a pressure chamber, the liquid container having a flexible portion and storing liquid therein, and the pressure chamber applying pressure to the flexible portion of the liquid container; a liquid ejection head, which ejects the liquid; liquid flow paths, which communicate the liquid containers with the liquid ejection head; and an air supply member, which supplies pressurized air to the pressure chambers for compressing the flexible portions so as to supply the liquid from the liquid containers to the liquid flow paths. The air supply member includes: a distribution member, which has an air intake portion for introducing the pressurized air, and air outlet portions for distributing the pressurized air to the liquid cartridges, and branch flow paths, which respectively communicate the air outlet portions with the pressure chambers of the liquid cartridges.

Abstract: The present invention relates to an ink-cartridge loading/unloading apparatus used in various devices onto which an ink-cartridge is capable of minimizing damage of a flexible printed wiring board of the ink-cartridge. The ink-cartridge loading/unloading apparatus according to the present invention comprises a vertically extending main body having a support portion; a mounting part connected to the front surface of the main body; and a coupling part connecting the main body and the mounting part. A metal coupling bar or a magnetic substance inserted in a coupling bar is attached to an electromagnet provided in a side of the main body, whereby the mounting part is coupled to the main body. The mounting part is released from a coupled state by pressing a button bar with an external force, and an elastic means is further provided between the mounting part and the main body.

Abstract: A method of manufacturing a liquid container, the liquid container including a liquid containing chamber in which a liquid can be contained, an air communicating passage allowing the liquid containing chamber to communicate with air, a liquid supply port for supplying the liquid contained in the liquid container to an outside, a liquid flow passage allowing the liquid container and the liquid supply port to communicate with each other, a differential pressure valve which is disposed in the liquid flow passage, which is normally urged to a closed state, and which is changed to an opened state when a differential pressure between a side of the liquid supply port and a side of the liquid containing chamber is equal to or more than a predetermined value, and a blocked portion formed by closing a bypass flow passage allowing a supply port side flow passage that is closer to the liquid supply port than the differential pressure valve to communicate with a containing chamber side flow passage that is closer to the l
