An ink jet recording apparatus comprises an ink tank (2) containing ink; a recording head (1) for performing recording by selectively ejecting ink; a mounting portion for mounting the ink tank and the recording head; a liquid passage (10) coupling portion provided on either or both of the ink tank (2) and the recording head (1) for separating or connecting the ink passages in the ink tank and the recording head; a holding portion provided on either or both of the ink tank (2) and recording head (1) for guiding the ink tank (2) to the recording head (1) in order to hold them separably; and an electrically or mechanically connecting portion provided on either or both of the recording head and mounting portion for electrically or mechanically connecting the recording head (1) to or separating it from the mounting portion.
摘要:
There is disclosed an ink jet cartridge composed integrally of a recording head (500) and an ink tank (250), which are constructed in mutually separable manner, in order to enable repeated use of the recording head (500) by tank replacement. In an ink supply part in the ink tank (250), an elastic partition wall is provided with a slit (110) which is normally closed but is opened under a predetermined pressure difference. The slit (110) is so designed as to generate an appropriate negative pressure on the recording head (580), thereby preventing ink leakage. Also a slit shielding valve (130) member is provided to shield the slit (110) at the abrupt inhaling action of the ink tank (250) at the detaching of the ink tank (500), in order to prevent air intrusion into the ink tank (500).
摘要:
A liquid storing container storing liquid therein and having a supply port (130) for supplying the liquid to the outside has flow rate control means having a slit (110) adapted to be closed in a steady state and to be opened for predetermined differential pressure or greater and controlling the flow rate of the liquid supplied from the supply port (130) to the outside, and pressure regulating means disposed more adjacent to the supply port (130) than to the flow rate control means for regulating the pressure of the liquid more adjacent to the supply port (130) than to the flow rate control means.
摘要:
An ink storage unit (IT) used in an ink jet recording apparatus for recording by ejecting ink comprises a plurality of ink storage chambers (910A), a plurality of movable walls (950) and a mechanism for holding each of the movable walls. Each of the ink storage chambers stores ink. Each of the movable walls (950) is provided in the each ink storage chamber (910A) respectively so as to seal stored ink against air, and each movable wall (950) can move according to a change of amount of ink in each ink storage chamber (910A). The mechanism for holding the movable walls exerts a force opposed to a force which is exerted on the each movable wall (950) according to the change of amount of ink, on each of of the movable walls (950) so as to make the pressure in each ink storage chamber an appropriate negative pressure.
