Embodiment Construction

[0066] Hereinafter, a liquid container and a liquid ejection device according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0067] figure 1 is a schematic diagram showing a liquid container and a liquid ejection device according to a first embodiment of the present invention.

[0068] figure 1 The inkjet printer 10 shown in , corresponds to the liquid ejection apparatus of the present invention, and the ink cartridge 20 detachably mounted on the inkjet printer 10 corresponds to the liquid container of the present invention.

[0069] In the inkjet printer 10 according to the first embodiment of the present invention, if air is ejected into the inner space 20A of the ink cartridge 20 by the pressurizing pump 11 through the air inlet duct 28, the ink pack 23 arranged in the inner space 20A Pressurized by air so that its volume is compressed. Accordingly, the ink in the ink pack 23 is squeezed out ...

Abstract

The cartridge stores the ink liquid supplied to the ink-jet head of the ink-jet printer in the ink pouch, and includes: a liquid supply port for allowing the ink liquid stored in the ink pouch to be supplied to the ink supply tube of the printer by connecting a liquid supply needle (not shown in the drawing) provided in the cartridge mounting portion when the ink cartridge is mounted on the cartridge mounting portion of the ink-jet printer; a remaining amount detection sensor which outputs a predetermined electric signal for notifying the main controller of the ink-jet printer of a fact that the remaining amount of the ink liquid reaches the near end when the remaining amount of the ink liquid stored in the ink pouch is consumed to the threshold value which is the near end; and an information memory from / to which information is readable and writable by the main controller of the ink-jet printer. The information memory stores correction information for correction the detection error of the remaining amount detection sensor when the near end is detected.

Description

technical field [0001] The present invention relates to a liquid container for supplying a storage liquid to the liquid ejection device and a liquid ejection device on which the liquid container is mounted. Background technique [0002] Examples of the liquid container and the liquid ejection device may include an ink cartridge for storing ink and an inkjet printer on which the ink cartridge is replaceably mounted. [0003] An ink cartridge for an inkjet printer has an ink supply port for supplying ink stored in a cartridge cavity to the printer. Ink stored in the ink chamber can be supplied to the printer by inserting an ink supply needle provided in the cartridge installation portion into the ink supply port when the ink cartridge is mounted on the cartridge installation portion of the printer. [0004] Furthermore, in order to prevent empty ejection of the print head in the printer, which can be caused when the ink stored in the ink cartridge is completely depleted, an i...
