Therefore, the operation proceeds to step S3 where the operations of various parts are maintained at rest. At step S5, the operator is promoted to insert the cartridge 27 into the recording apparatus.
  • step S7 If the resistance is zero, it is discriminated that the cartridge 27 is easily retracted. Therefore, the operation proceeds to step S7, where the operations of various parts are stopped. Subsequently, at step S9, the operator is promoted to assuredly set the cartridge 27.

  • the cover 401 is disposed so as to block the cartridge inserting path it is made of a metal plate having a thickness of 0.8 mm, for example. It has an area substantially equal to the sectional area of the ink cartridge. Therefore, when the cartridge inserting path 33 is blocked by the cover 401, it does not provide enough space for permitting insertion of the operator's finger or other foreign matters beyond the cover 401. Therefore, the needle 314 and/or the residual ink pipe 318 are protected from them.

  • the projection 405a When the cartridge 27 is inserted into the inserting path 33, the projection 405a is faced to the tapered portion 406b. Therefore, when the cartridge is in the process of being inserted, the projection 405a enters the gap between the cover 401 and the frame 408 beyond the cover 401 until it contacts the tapered portion 406b of the stopper 406.
  • the projection 405 lowers the tapered portion 406b so as to retract the tapered portion 406b away from the insertion path 33, until the pawl 406a of the stopper 406 is released from the cover 401.

  • the cover opening and closing mechanism is engageable with the projection of the cartridge, and therefore, it requires only small additional space, and the structure is simple.
  • 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. 4,723,129 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.
  • 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 is 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 small and simple structure is enough to prevent the erroneous mounting of the ink cartridge and from the contamination with the ink.
