Problems solved by technology

This ink sticking to the detection mechanism may lead to false detections of: whether the ink cartridge has been attached to the printer; and whether the amount of ink remaining in the ink cartridge is less than a predetermined amount

[0052] Will be in reference Figure 1 to 11 At the same time, the ink cartridge 30 according to the first embodiment of the present disclosure is described.

[0053]

[0054] First, refer to figure 1 The printer 10 suitable for using the ink cartridge 30 is described.

[0055] The printer 10 (an example of the system) is configured to form an image by selectively ejecting ink droplets onto a sheet based on an inkjet recording system. Such as figure 1 As shown in, the printer 10 includes a recording head 21, an ink supply device 100, and an ink tube 20 connecting the recording head 21 to the ink supply device 100. The ink supply device 100 includes a cartridge receiving part 110 (an example of a cartridge receiving part). The cartridge receiving portion 110 can detachably receive the ink cartridge 30 (an example of a liquid cartridge) in the cartridge receiving portion 110.

[0056] In particular, the box receiving portion 110 has a side where the opening 112 is formed. The ink car...

Abstract

A liquid cartridge includes: a cartridge body accommodating a reservoir; a liquid-supply part; a movable member movably supported by the cartridge body; an urging member provided on the movable member; and a contact member provided at a surface of the reservoir. The movable member includes a detected part movable from a first position, to a second position rearward of the first position, and to a third position rearward of the second position, the detected part at the first position and at the second position being positioned higher relative to the cartridge body. The urging member is resiliently deformable, the urging member in a deformed state being deformed to urge the detected part toward the third position. The contact member can contact the movable member, the contact member in contact with the movable member restricting the detected part at the second position from moving to the third position.

Description

Technical field [0001] The present disclosure relates to a liquid cartridge that can be attached to a device such as a printer, and also relates to a system using the liquid cartridge. Background technique [0002] Conventionally, there is known an ink cartridge that can be detachably attached to a device such as a printer. Various detections can be performed on the ink cartridge attached to the device: for example, whether the ink cartridge has been attached to the printer; and whether the residual amount of ink stored in the ink cartridge is less than a predetermined amount. Japanese Utility Model Registration No. 3,157,392 discloses an ink cartridge for which these tests are performed. [0003] In the above-mentioned ink cartridge, it is completely independently detected whether the ink cartridge has been attached to the printer and whether the residual amount of ink stored in the ink cartridge is less than a predetermined amount. Therefore, this structure leads to an increase...
