Definitions

  • the present invention relates to an ink container cartridge containing ink to be supplied to the recording head and a manufacturing method therefor.
  • the types of the recording heads include a wire dot type, a heat sensitive type, a heat transfer type or an ink jet type.
  • the ink jet type is recently particularly noted because of its low running cost and lost noise, since the ink is directly ejected to the recording sheet.
  • the ink jet recording apparatus of the ink jet type uses a recording head cartridge which is detachably mountable to the recording apparatus, the recording head cartridge comprising the recording head and an integral ink container.
  • the ink container (ink supply source) is made detachably mountable to the main assembly of the recording apparatus, so as to permit the operator replaces the used-up ink container with a flesh ink container.
  • Such a type of ink container is called ink cartridge.
  • the ink container cartridge may include an ink bladder coated with aluminum laminate or the like in consideration of prevention from the ink deterioration by being exposed to light, the sealing of the ink and against the air, and the pressure balance in the ink supply system.
  • the ink bladder may be accommodated in a casing.
  • the ink bladder is provided with a plug made of rubber or the like.
  • the ink supply is established by piercing the plug with a hollow needle of an ink supply system of the ink jet recording apparatus main assembly. The meniscus retaining force at the ink ejection outlets and the static head difference between the recording head and the ink container cartridge are balanced, and the ink is supplied into the recording head by the capillary action of the ink supply system such as tube.
  • the ink flows in the opposite direction in the ink container with the result of trouble in the operation.
  • the connecting portion between the ink supply system and the recording head is opened to the air, and therefore, the balance between the meniscus of the recording head and the static head difference is disturbed with the result of the reverse flow of the ink to the ink container, and a great quantity of the air may be introduced in the ink supply system, that is, the tube, for example. This will be described in detail in comparison with the embodiment of the present invention.
  • the air is positively introduced through the ejection outlets, and then, the air is sucked out to remove at once the various foreign matters such as air bubbles, dust and viscosity increased ink stagnating in the neighborhood of a common ink chamber, together with the introduced air.
  • the balance between the meniscus and the head difference is disturbed, with the result that the ink in the ink supply tube returns into the ink container, and the ink supply tube is filled with the air.
  • the ink in the ink supply system flows back into the ink container, and the air is introduced, the quantity of ink is significantly large in order to recover the ejection operation by the sucking of the ink to restabilize the ink supply system, so that the great amount of ink is consumed without recording.
  • the pressure in the ink container is vacuum, and therefore, there is a liability of introducing the air into the ink container. If the air is introduced into the air, no sufficient ink supply can not be achieved with the result of interruption of the printing operation. If the ambient condition change occurs, particularly from the temperature change from low temperature to the high temperature causes expansion of the air, with the result of pressurized ink container. If this occurs, the ink may leak out.
  • U.S. Patent No. 4,931,812 proposes that an "L" shaped ink passage connecting the recording head and the ink container is utilized, and a ball is placed therein to prevent introduction of the air.
  • the structure is not usable with the ink container cartridge because it is directed to the recording head cartridge.
  • an ink container cartridge comprising: an ink containing portion; a plug for being pierced by a hollow needle; means for preventing reverse flow of the ink to said containing portion, said preventing means comprising a valve, a first liquid passage in which said valve is movable and a second passage disposed closer to said ink containing portion than said first passage, and said valve is capable of closing the second passage.
  • a method of manufacturing an ink cartridge comprising: preparing an ink container having an ink containing portion, a liquid passage communicating with the ink containing portion and a plug for plugging the liquid passage; filling the containing portion with ink; mounting a valve into the liquid passage; mounting the plug; effecting sucking through the plug to discharge air from said containing portion.
  • said valve is set between the projections before said plugging step, and the valve is urged inwardly beyond the first projection.
  • an ink jet recording apparatus comprising: an ink container cartridge including an ink containing portion; a plug for being pierced by a hollow needle; means for preventing reverse flow of the ink to said containing portion, said preventing means comprising a valve, a first liquid passage in which said valve is movable and a second passage disposed closer to said ink containing portion than said first passage, and said valve is capable of closing the second passage; a recording head having a portion detachably mounting said ink container cartridge; means for receiving the recording head; and recovery means for recovering operation of said recording head.
  • the recovery means may introduced the air through the ink ejection outlets of the recording head prior to the recovering operation.
  • the reverse flow of the ink to the ink container is effectively prevented, and therefore, the introduction of the air into the ink supply system can be prevented when the recording head is dismounted or in the recovery operation in which the air is introduced through the ejection outlets. Therefore, the quantity of the ink consumed for the ejection recovery operation for refilling the ink in the ink supply system or the recording head, can be reduced.

  • the clearance t is not particularly considered. This is similar to the case of the second embodiment.
  • the present invention is particularly suitably usable in an ink jet recording head and recording apparatus wherein thermal energy by an electrothermal transducer, laser beam or the like is used to cause a change of state of the ink to eject or discharge the ink. This is because the high density of the picture elements and the high resolution of the recording are possible.
  • the typical structure and the operational principle are preferably the ones disclosed in U.S. Patent Nos. 4,721,129 and 4,740,796.
  • the principle and structure are applicable to a so-called on-demand type recording system and a continuous type recording system. Particularly, however, it is suitable for the on-demand type because the principle is such that at least one driving signal is applied to an electrothermal transducer disposed on a liquid (ink) retaining sheet or liquid passage, the driving signal being enough to provide such a quick temperature rise beyond a departure from nucleation boiling point, by which the thermal energy is provided by the electrothermal transducer to produce film boiling on the heating portion of the recording head, whereby a bubble can be formed in the liquid (ink) corresponding to each of the driving signals.
  • the liquid (ink) is ejected through an ejection outlet to produce at least one droplet.
  • the driving signal preferably in the form of a pulse, because the development and contraction of the bubble can be effected instantaneously, and therefore, the liquid (ink) is ejected with quick response.
  • the driving signal in the form of the pulse is preferably such as disclosed in U.S. Patents Nos. 4,463,359 and 4,345,262.
  • the temperature increasing rate of the heating surface is preferably such as disclosed in U.S. Patent No. 4,313,124.
  • the structure of the recording head may be as shown in U.S. Patent Nos. 4,558,333 and 4,459,600 wherein the heating portion is disposed at a bent portion, as well as the structure of the combination of the ejection outlet, liquid passage and the electrothermal transducer as disclosed in the above-mentioned patents.
  • the present invention is applicable to the structure disclosed in Japanese Laid-Open Patent Application No. 123670/1984 wherein a common slit is used as the ejection outlet for plural electrothermal transducers, and to the structure disclosed in Japanese Laid-Open Patent Application No. 138461/1984 wherein an opening for absorbing pressure wave of the thermal energy is formed corresponding to the ejecting portion. This is because the present invention is effective to perform the recording operation with certainty and at high efficiency irrespective of the type of the recording head.
  • the present invention is effectively applicable to a so-called full-line type recording head having a length corresponding to the maximum recording width.
  • a recording head may comprise a single recording head and plural recording head combined to cover the maximum width.
  • the present invention is applicable to a serial type recording head wherein the recording head is fixed on the main assembly, to a replaceable chip type recording head which is connected electrically with the main apparatus and can be supplied with the ink when it is mounted in the main assembly, or to a cartridge type recording head having an integral ink container.
  • the provisions of the recovery means and/or the auxiliary means for the preliminary operation are preferable, because they can further stabilize the effects of the present invention.
  • preliminary heating means which may be the electrothermal transducer, an additional heating element or a combination thereof.
  • means for effecting preliminary ejection (not for the recording operation) can stabilize the recording operation.
  • the recording head mountable may be a single corresponding to a single color ink, or may be plural corresponding to the plurality of ink materials having different recording color or density.
  • the present invention is effectively applicable to an apparatus having at least one of a monochromatic mode mainly with black, a multi-color mode with different color ink materials and/or a full-color mode using the mixture of the colors, which may be an integrally formed recording unit or a combination of plural recording heads.
  • the ink has been liquid. It may be, however, an ink material which is solidified below the room temperature but liquefied at the room temperature. Since the ink is controlled within the temperature not lower than 30 °C and not higher than 70 °C to stabilize the viscosity of the ink to provide the stabilized ejection in usual recording apparatus of this type, the ink may be such that it is liquid within the temperature range when the recording signal is the present invention is applicable to other types of ink. In one of them, the temperature rise due to the thermal energy is positively prevented by consuming it for the state change of the ink from the solid state to the liquid state. Another ink material is solidified when it is left, to prevent the evaporation of the ink.
  • the ink is liquefied, and the liquefied ink may be ejected.
  • Another ink material may start to be solidified at the time when it reaches the recording material.
  • the present invention is also applicable to such an ink material as is liquefied by the application of the thermal energy.
  • Such an ink material may be retained as a liquid or solid material in through holes or recesses formed in a porous sheet as disclosed in Japanese Laid-Open Patent Application No. 56847/1979 and Japanese Laid-Open Patent Application No. 71260/1985. The sheet is faced to the electrothermal transducers. The most effective one for the ink materials described above is the film boiling system.
  • the ink jet recording apparatus may be used as an output terminal of an information processing apparatus such as computer or the like, as a copying apparatus combined with an image reader or the like, or as a facsimile machine having information sending and receiving functions.
  • the reverse flow of the ink to the ink container is effectively prevented. Therefore, the introduction of the air into the ink supply system during the ejection recovery operation including the air charging through the ejection outlets and when the recording head is dismounted. Thus, the consumption of the ink in the recovery operation or the ink refilling operation can be reduced.
