Problems solved by technology

That is, an inkjet recording apparatus using the "electrode method" (that is, the method uses a pair of electrodes to measure the remaining amount of ink in each ink container) suffers from the problem that each recording liquid container needs to be equipped with a pair of electrodes, and Components associated with it, so the cost is higher
[0021] Also, in the case of the design disclosed in Japanese Laid-Open Patent Application 2003-159808, in order to accurately detect the ink cartridge sequence, a wireless communication system with a relatively short data transmission-reception range is used

Embodiment approach 1

[0051] figure 1 is a sectional view of the recording liquid container for the inkjet recording apparatus in the first embodiment of the present invention, in which the section is parallel to the side wall of the container. This figure shows the recording head unit 405 and the recording liquid container 1 in their proper positions on the carriage 205 ( Figure 5 ). The recording liquid container 1 is detachably mountable in the inkjet recording apparatus. Although not shown in this figure, the main assembly of the recording apparatus supports a plurality of recording liquid containers 1 storing inks of different colors and juxtaposed in a direction perpendicular to the drawing plane. Each recording liquid container 1 has a first engaging portion 5 and a second engaging portion 6 . The first engaging portion 5 is engaged with the first engaging portion 455, in which the recording head unit 405 is provided with the first engaging portion 455, and the second engaging portion 6 ...

Embodiment approach 2

[0087] Figure 8 is a perspective view of the inkjet recording apparatus in the second embodiment of the present invention, whose recording liquid container chamber 602 is located at the bottom of its main assembly. exist Figure 8 In , the cover 614 of the recording liquid container chamber 602 is opened, and thus, the recording liquid container chamber 602 is exposed. In the recording liquid container chamber 602 there are recording liquid containers 701K, 701C, 701M, and 701Y. Since each recording liquid container 701 is installed in the recording liquid container chamber 601, it becomes connected to an ink supply pipe (not shown) or the like, so that ink in the recording liquid container 701 may be supplied to a recording head (not shown) . The recording apparatus 600 in this embodiment is constructed so that the recording liquid container is fixed directly to the main assembly itself of the recording apparatus instead of being mounted on a bracket. Thus, the size of t...

[0092] Figure 11 is a sectional view of a main part of an inkjet recording apparatus in a third embodiment of the present invention, more specifically, a recording liquid container chamber, a tray, a recording medium carrying unit, etc., in which the section is parallel to the side wall of the recording liquid container . The carriage 605 includes a printing head that moves in a direction perpendicular to the drawing in a manner of scanning the recording medium to print an image on the recording medium. The printing medium is fed to the main assembly of the recording apparatus by a paper feed roller 631, and is discharged after moving along a platen 632, a paper discharge roller unit 633, a spur 634, and the like.

[0093] In this embodiment, the recording liquid container chamber of the recording device is located at the top front of the main assembly of the recording device, and a plurality of recording liquid containers are located side by side in the direction parallel t...

Abstract

A recording apparatus to which a recording liquid accommodating container having a recording liquid accommodating portion is mountable, wherein the recording liquid accommodating container including communicating means for bi-directional wireless communication with the recording apparatus, the recording apparatus including a communication antenna for wireless communication with the communicating means; wherein the communication antenna and the communicating means are adapted to be disposed opposed to each other with the recording liquid accommodating portion interposed therebetween, and wherein it is discriminated depending on a state of wireless communication between the communication antenna and the communicating means whether or not a remaining amount of the recording liquid in the recording liquid accommodating portion is not more than a predetermined amount.

Description

technical field [0001] The present invention relates to a recording apparatus, a method for determining the remaining amount of recording liquid, and more particularly, to a system for determining the remaining amount of recording liquid in an inkjet printing apparatus. [0002] The present invention also relates to an ink cartridge detachably mountable in a main assembly of a recording apparatus, and to an ink jet printer in which a plurality of such ink cartridges are mounted so that the printer can record images. In particular, the present invention relates to a wireless communication system for obtaining information, such as the position of an ink cartridge relative to an ink cartridge holder, that is specific to each ink cartridge. Background technique [0003] Inkjet recording apparatuses using a plurality of inks of different colors have been known for a long time. Some of such inkjet recording apparatuses are constructed so that a plurality of recording liquid conta...
