Problems solved by technology

[0014] For users, such long-term use will lead to high operating costs. In addition, when disposing of ink cartridges, they still face the problem of increasing the burden of disposing of residual ink.
[0015] This phenomenon is especially prone to this problem for the composition of the ink bag pressurized by the pressurized air injected into the ink cartridge housing.

Embodiment Construction

[0067] Next, first to third ink cartridges for printers according to the present invention will be described based on the illustrated embodiments.

[0068] First, FIG. 1(A) shows a plan view of an example of an ink jet printer obtained by using the ink cartridge of the first form according to the present invention. In Fig. 1 (A), the symbol 1 represents the pinch roller, and the pinch roller 1 is guided by the scanning guide part 4 by means of the toothed belt 3 driven by the pinch roller motor 2, along the longitudinal direction of the paper feeding part 5, i.e. The scanning direction in the width direction of the printing paper reciprocates.

[0069] Although not shown in FIG. 1(A), an ink jet print head 6 to be described later is mounted on the surface of the nip roller 1 facing the paper feeding member 5 .

[0070] On the nip roller 1, sub-tanks 7a-7d for supplying ink to the above-mentioned printing heads are loaded. These sub-ink tanks 7a-7d are equipped with 4 sub-ink...

Abstract

An ink cartridge of the first embodiment is constituted of an ink pack and an outer shell case for preventing close contact between interior surfaces of the ink pack when a reduction arises in the amount of ink stored in the ink pack. An ink cartridge according to the second and third embodiment forms ink channel at at least a surface of the flexible material constitutes the ink pack. When interior ink reduces, residual ink is guided to the channel and flows out. Such ink box is accommodated in the external contour housing with an airtightness shape and suitable for supply the ink to the printer by air pressure that may improve the utilization rate of the ink in the ink pack.

Description

technical field [0001] The present invention relates to an ink cartridge used in an ink jet printer. The ink cartridge is provided with a flat pouch-like ink bag formed of a flexible material, and the ink bag is accommodated in a case constituting the outer contour of the ink cartridge. Background technique [0002] Inkjet printers generally have an inkjet printhead mounted on a nip roller that moves along the width direction of the printing paper and a paper feeder that relatively moves the printing paper in a direction perpendicular to the moving direction of the printing head. The device performs printing by ejecting ink droplets from the print head onto the printing paper based on the printing information. [0003] And for this kind of printer provided for office or business use, in order to adapt to a large amount of printing tasks, must be equipped with large-capacity ink cartridge, therefore, provide a kind of printer that ink cartridge is contained in the ink cartrid...
