。A conventional inkjet recording cartridge of this type is constructed as shown in FIGS. 7 and 8, for example. In these figures, 1 is an inkjet recording head unit (hereinafter simply referred to as a recording head) that ejects ink to form flying droplets, 2 is an ink ejection port formed in the recording head 1, and 3 is a recording head. An electrode that receives and takes signals for driving the head 1; 4 an ink storage body that supplies ink to be ejected from the recording head 1; 5 an ink storage body 4;
a supply hole 6 for supplying ink from the recording head 1 to the recording head 1;
is a housing that holds the ink storage body 4 and the recording head 1;
7 is a lid that holds the ink container 4 between itself and the housing 6; 8 is a fixing member that holds the recording head 1 between it and the housing 6;

するのを防止している。This inkjet recording cartridge has a carriage lO which is movable along a guide shaft 9 as shown in FIG.
A recording sheet 12 is mounted on the platen 11 and held on the platen 11.
This is a so-called disposable type recording cartridge, in which recording is performed by ejecting ink from the recording head towards the target, and when all the ink in the ink container 4 is consumed, it is replaced with another new recording cartridge. Therefore,
Such an inkjet recording cartridge is normally stored in a sealed disposable container 12 made of a non-gas permeable material such as aluminum foil, as shown in FIG. This prevents clogging of the ejection port due to thickening of the ink due to evaporation of the ink solvent or adhesion of dust until it is delivered to the user's hands and used.

った。[Problems to be Solved by the Invention] However, in the conventional recording cartridge as described above, when it is taken out from the sealed container and loaded into the recording device at the beginning of use, the ejection surface of the recording head is exposed, so that it may be inadvertently damaged. If your hand or clothing comes into contact with the discharge surface,
Dust, sweat, fat, etc. may contaminate the discharge surface, resulting in non-discharge or
Otherwise, inconveniences such as curly printing often occur, and hands and clothes are often stained with ink. Moreover, the electrode 3 that receives and receives the print signal that drives the recording head is also easily touched by hands, which tends to cause the electrode to become dirty due to sweat and the like, and to cause electrical contact failure due to oxidation. Furthermore, in actual use of this inkjet recording cartridge, there are many cases where the ink inside the ink container is not used up, such as when replacing the recording cartridge with another color. No consideration was given to preservation.
