And an openable cover that can be opened and closed from the outside is provided. Therefore, the distance between the reading unit and the recording unit in the front-rear direction can be made smaller than that of the conventional apparatus, and as a result, the entire apparatus can be downsized. Further, by opening the opening / closing cover, it is possible to easily attach / detach a replacement part unit such as an ink cartridge in the recording unit.

In the above-mentioned apparatus, the reading unit has a reading unit and a document table, and the reading unit is disposed on the upper front side of the recording unit, and the document table is located at a position above the recording unit and not overlapping with the opening / closing cover. Can be arranged. As a result, the upper margin space of the recording unit can be effectively used as the arrangement unit of the document table of the reading unit, so that the apparatus can be configured more compactly.

As described above, in the present embodiment, the ink jet recording system for discharging ink from the recording head for recording is used. That is, the recording head has a fine liquid ejection port (orifice), a liquid path, and an energy action section provided in a part of the liquid path, and an energy generation section for generating a droplet forming energy to act on the liquid in the action section. Means.

As a recording method provided with an energy generating means for generating such energy, a recording method using an electromechanical transducer such as a piezo element, an electromagnetic wave such as a laser beam is irradiated to generate heat, and the heat is generated. A recording method using an energy generating means for discharging liquid droplets by an action, or a recording method using an energy generating means for discharging a liquid by heating a liquid with an electrothermal converter such as a heating element having a heating resistor. is there.

Among them, a recording head used in an ink jet recording method for discharging a liquid by thermal energy has a high density of liquid discharge ports (orifices) for discharging a recording liquid droplet to form a discharge liquid droplet. Since they can be arranged, high-resolution recording can be performed.
Among them, a recording head using an electrothermal transducer as an energy generating means is advantageous because it can be easily made compact, can be easily mounted at high density, and has a low manufacturing cost.

In the present embodiment, the ink is ejected by energizing the electrothermal transducer in accordance with the recording signal, and utilizing the boiling film generated in the ink by the thermal energy to grow and shrink the bubbles generated in the ink. The recording is performed by discharging the ink from the discharge port.

The typical configuration and principle are described in, for example, US Pat. Nos. 4,723,129 and 47407.
What is performed using the basic principle disclosed in Japanese Patent No. 96 is preferable.

This method can be applied to any of the so-called on-demand type and continuous type. In particular, in the case of the on-demand type, it is applicable to a recording sheet or a liquid path holding a liquid (ink). By applying at least one drive signal corresponding to the recorded information and providing a rapid temperature rise exceeding the film boiling to the electrothermal transducer arranged in the manner described above, heat energy is generated in the electrothermal transducer. This is effective because film boiling occurs on the heat-acting surface of the recording head, and as a result, bubbles in the liquid (ink) corresponding to this drive signal on a one-to-one basis are formed. The growth of this bubble,
By discharging the liquid (ink) through the discharge opening by contraction, at least one droplet is formed. When this drive signal is formed into a pulse shape, the growth and shrinkage of the bubble are immediately and appropriately performed, and therefore, the ejection of liquid (ink) having particularly excellent responsiveness can be achieved, which is more preferable.

As the pulse-shaped drive signal, those described in US Pat. Nos. 4,463,359 and 4,345,262 are suitable. In addition, U.S. Pat.
If the conditions described in the specification of JP-A No. 13124 are adopted, more excellent recording can be performed.

As the configuration of the recording head, a combination configuration of a discharge port, a liquid path, and an electrothermal converter (a linear liquid flow path or a right-angled liquid flow path) as disclosed in the above-mentioned respective specifications.
U.S. Pat. Nos. 4,558,333 and 44, which disclose a configuration in which a heat acting surface is arranged in a bending region in addition to the above.
The configuration according to 59600 is also applicable to the present invention.

Japanese Unexamined Patent Publication (Kokai) No. 59-123670 discloses a configuration in which a common slot is used as a discharge portion of an electrothermal converter for a plurality of electrothermal converters, and an opening for absorbing pressure waves of thermal energy. May be configured based on JP-A-59-138461, which discloses a configuration in which is adapted to a discharge unit. That is, regardless of the form of the recording head, the recording can be reliably and efficiently performed in the present invention.

It is preferable to add recovery means, preliminary auxiliary means, and the like for the recording head constituting the recording means 310 of the present invention since the effect of the recording means 310 of the present invention can be further stabilized. It is. Specific examples include capping means for the recording head, cleaning means, pressurizing or suction means, an electrothermal conversion type or a preheating means using a heating element different from these or a combination thereof, and the original recording Performing a preliminary ejection mode in which ejection is performed separately from the above is also effective for performing stable printing.

The recording mode of the recording unit 300 is not limited to recording only the mainstream color such as black, but may be at least one recording mode of multiple colors of different colors or full color by mixing colors. In that case, the recording head may be configured integrally or a combination of a plurality of recording heads.

In the embodiments described above, the ink is described as a liquid. However, any ink that can be solidified at room temperature or lower can be used if it can be made into a liquid by softening or liquefying means in advance. In the recording method, it is general that the temperature of the ink itself is adjusted within a range of 30 ° C. to 70 ° C. and the viscosity of the ink is set to a stable ejection range. Good.

Generally, the range of ink used can be expanded by positively utilizing the temperature rise by thermal energy as the energy for changing the state of the ink from the solid state to the liquid state. The method of applying thermal energy to the ink may be either a method of applying the thermal energy before reaching the recording head or a method of applying a recording signal by thermal energy to the recording head. Further, an ink which has already started solidifying when the liquid is ejected and reaches the recording medium, and an ink which is solid in a standing state to prevent evaporation but which liquefies by heating can be used.

Such an ink is disclosed, for example, in JP-A-54-5
As described in Japanese Patent No. 6847 and Japanese Patent Application Laid-Open No. Sho 60-71260, while being held in a liquid state or a solid state in a concave portion or a through hole of a porous sheet, it is disposed so as to face an electrothermal converter. It is good also as a form used.
