Embodiment Construction

[0084] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0085] FIG. 1 is a sectional view of an ink cartridge according to an embodiment of the present invention. The basic structure of the ink cartridge 1 of this embodiment is the same as that of the ink cartridge 101 shown in FIGS. 10A to 10C . That is, the case body 4 is constituted by the cup portion 2 and the lid portion 3 . Inside the box body 4 , the partition wall 14 formed in the cup-shaped portion 2 with the communicating portion 9 at the lower portion is divided into the ink storage chamber 6 that will directly store or has stored ink and the negative pressure that accommodates the negative pressure generating member 11. Component accommodating chamber 5 occurs. An ink supply port 10 and an air communication port 8 are formed on a wall surface forming the negative pressure generating member housing chamber 5 . The air communication port 8 is formed in the cover...

Abstract

A residual ink amount detection module (20) has a supporting substrate (21), an information storage element (22) provided on the first surface (21b) of the supporting substrate (21), and an external contact electrode (24) provided on the second surface (21c) of the supporting substrate (21). Two through-holes (21a) are formed in the supporting substrate (21) so as to penetrate from its first surface (21b) to its second surface (21c). A sealing structure body (23) covering the information storage element (22) and the through-holes (21a) is provided on the first surface (21b) of the supporting substrate (21). The sealing structure body (23) is constructed from a light transmitting member and formed into a prism shape. The residual ink amount detection module (20) is fixed to a cup part (2) constituting a part of the housing of the ink tank with the sealing structure body (23) exposed into an ink containing chamber (6).

Description

technical field [0001] The present invention relates to an ink remaining amount detection unit for detecting the remaining amount of ink in an ink cartridge storing ink supplied to an inkjet recording head in inkjet recording, an ink cartridge having the ink remaining amount detecting unit, and an inkjet recording apparatus. Background technique [0002] In inkjet recording, at least a recording head that ejects ink and an ink cartridge that stores ink supplied to the recording head are used. Ink is a consumable, and therefore, in an inkjet recording device, it is constructed so that the ink cartridge can be freely attached to and detached from the inkjet recording device in a single piece or in the form of a cartridge integrated with the recording head, and when the ink in the ink cartridge is used up, Replace with a new ink cartridge. [0003] In the existing inkjet recording equipment, in order to let the user know the replacement time of the ink cartridge, the technolog...
