Furthermore, since the document discharge tray 8 is rotatable, the document discharge tray 8 can be rotated by a predetermined amount and installed even when there is no space behind the apparatus or there is an obstacle, thus reducing the installation area of the apparatus. This can save space.

In the above-described embodiment, the ink jet recording system is used as the recording means, but the electrothermal converter is energized according to a recording signal, and the thermal energy applied by the electrothermal converter produces ink. More preferably, recording is performed by ejecting the ink from the ejection port due to the growth and contraction of bubbles generated in the ink by utilizing the film boiling.

With regard to its typical structure and principle, it is preferable to use the basic principle disclosed in, for example, US Pat. Nos. 4,723,129 and 4740796. This method can be applied to both the so-called on-demand type and continuous type, but in the case of the on-demand type in particular, it is arranged corresponding to the sheet or liquid path holding the liquid (ink). By applying at least one drive signal to the electrothermal transducer, which corresponds to the recorded information and gives a rapid temperature rise beyond nucleate boiling,
This is effective because heat energy is generated in the electrothermal converter to cause film boiling on the heat acting surface of the recording head, and as a result, bubbles in the liquid can be formed in a one-to-one correspondence with this drive signal. Due to the growth and contraction of the bubbles, the liquid is ejected through the ejection openings to form at least one droplet. It is more preferable to make this drive signal into a pulse shape because bubbles can be grown and contracted immediately and appropriately, so that particularly excellent liquid ejection can be achieved.

As the pulse-shaped drive signal, those described in US Pat. Nos. 4,463,359 and 4,345,262 are suitable. If the conditions described in US Pat. No. 4,313,124 of the invention relating to the rate of temperature rise on the heat acting surface are adopted, more excellent recording can be performed.

As the constitution of the recording head, in addition to the combination constitution of the discharge port, the liquid passage, and the electrothermal converter (the straight liquid passage or the right-angled liquid passage) as disclosed in the above-mentioned respective specifications. The present invention also includes configurations using US Pat. Nos. 4,558,333 and 4,459,600, which disclose configurations in which the heat acting portion is arranged in a bending region.

Further, JP-A-59-123670, which discloses a structure in which a common slit is used as a discharge portion of a plurality of electrothermal converters, and an opening for absorbing a pressure wave of thermal energy are disclosed. Japanese Patent Laid-Open Publication No.
The effect of the present invention is effective even if the configuration is based on Japanese Patent Laid-Open No. 59-138461. That is, according to the present invention, recording can be surely and efficiently performed regardless of the form of the recording head.

Further, the present invention can be effectively applied to a full-line type recording head having a length corresponding to the maximum width of the recording medium on which the recording section can record. As such a recording head, by combining a plurality of recording heads,
Either a structure satisfying the length or a structure as one recording head integrally formed may be used.

In addition, even in the case of the serial type described above, it is possible to electrically connect to the apparatus main body and supply ink from the apparatus main body by mounting the recording head fixed to the carriage or the carriage. A replaceable chip type recording head or the like may be used.

Further, it is preferable to add a recovery means for the recording head, a preliminary auxiliary means, etc., provided as the structure of the recording section of the present invention, because the effects of the present invention can be further stabilized. Specifically, these are capping means, cleaning means, pressurizing or suctioning means for the recording head, preheating means by electrothermal conversion type or other heating element or a combination thereof, and recording. It is also effective to perform a stable recording by performing a preliminary discharge mode in which another discharge is performed.

Regarding the type and number of recording heads mounted on the carriage, for example, only one is provided corresponding to a single color ink, or a plurality of inks having different recording colors and densities are supported. And a plurality of them may be provided. That is, for example, the recording mode of the recording unit is not limited to the recording mode of only the mainstream color such as black, but may be a combination of a plurality of recording heads integrally formed, but a mixed color of different colors or a mixed color It is also applicable to a device with at least one of the full colors according to

In addition, although the ink is described as a liquid in the above-mentioned embodiments, it is an ink which solidifies at room temperature or lower and softens or liquefies at room temperature, or in the ink jet recording system. 30 inks
Generally, the temperature is controlled in the range of ℃ to 70 ℃ to control the temperature of the ink so that the viscosity of the ink is within the stable ejection range. good. In addition, it is possible to prevent the temperature rise due to thermal energy from being positively used as the energy for changing the state of the ink from the solid state to the liquid state, or to use ink that solidifies when left standing for the purpose of preventing ink evaporation. However, in any case, when heat ink is liquefied by applying heat energy according to the recording signal and liquid ink is ejected, or when the ink reaches the recording sheet, it begins to solidify. It is also applicable when using an ink that has the property of being liquefied for the first time by energy.

The ink in such a case is described in JP-A-54-5.
As described in Japanese Patent No. 6847 or Japanese Patent Laid-Open No. 60-71260, a mode in which it is opposed to the electrothermal converter in a state of being held as a liquid or a solid in the concave portion or through hole of the porous sheet. Also good. The most effective one for each of the above-mentioned inks is to execute the above-mentioned film boiling method.

Further, although an example in which the ink jet recording system is used as the above-mentioned recording means has been described, the present invention does not need to be limited to the ink jet recording system, and other thermal transfer recording system and thermal recording system, and further, The recording method other than the impact recording method such as the wire dot recording method can be applied. Further, it is not necessary to limit to the serial recording method, and a so-called line recording method may be used.

Although the present embodiment has been described by using the facsimile machine as the reading and recording apparatus, the present invention is not limited to this, and another apparatus such as a copying machine may be used.

As described above, according to the present invention, the discharge loading means is rotatably attached to the cover member so that the user can open the cover member without removing the discharge loading means. The operability can be improved as compared with. Further, even if there is no installation space on the back side of the apparatus, the cover member can be opened and closed by folding the discharge and stacking means. Further, since the discharging and loading means is rotatable, the discharging and loading means can be rotated by a predetermined amount and installed even when there is no space behind the apparatus or when there is an obstacle, thus reducing the installation area of the apparatus. This can save space.
