Further, the signal connector section 25 delivers and receives signals from the host device 300 and exchanges control signals and the like between the two devices.

When the recording unit 100 is attached to the feeding unit 200 as described above, this is detected by the mechanical switch S ₁ operated by a pin or the like protruding from the feeding unit 200, and the recording unit control circuit is detected. The control mode switching means C ₀ set to C operates. The control mode switching means C ₀ switches the electronic switch S ₂ made of a semiconductor to apply a voltage of the power supply device 22 higher than the voltage of the recording section battery D to the driven section including the recording section R and the driving sections A and B.

By applying at least one drive signal to the electrothermal transducer arranged corresponding to the sheet or liquid path in which is stored, which corresponds to the recorded information and gives a rapid temperature rise exceeding nucleate boiling. The heat energy is generated in the electrothermal converter to cause film boiling on the heat acting surface of the recording means (recording head), and as a result, bubbles in the liquid (ink) can be formed in one-to-one correspondence with this drive signal. So effective.

Due to the growth and contraction of the bubbles, the liquid (ink) is ejected through the ejection opening to form at least one droplet. It is more preferable to make this drive signal into a pulse shape because bubbles can be immediately and appropriately grown and contracted, so that liquid (ink) ejection with excellent responsiveness can be achieved. As this pulse-shaped drive signal, US Pat.

In addition, Japanese Unexamined Patent Publication No. 59-123670 discloses a configuration in which a common slit is used as a discharge portion of the electrothermal converter for a plurality of electrothermal converters, and an opening for absorbing a pressure wave of thermal energy is provided. The effect of the present invention is effective even if the configuration corresponding to the ejection portion is disclosed in JP-A-59-138461. That is, according to the present invention, recording can be reliably and efficiently performed regardless of the form of the recording head.

Furthermore, the present invention can be effectively applied to a full-line type recording head having a length corresponding to the maximum width of a recording material that can be recorded by the recording apparatus. Such a recording head may have a configuration that satisfies the length by a combination of a plurality of recording heads or a configuration as one recording head integrally formed. in addition,
Even if the serial type as in the above example is replaced with a recording head fixed to the device body or mounted on the device body, electrical connection with the device body and ink supply from the device body are possible. The present invention is also effective when a flexible chip type recording head or a cartridge type recording head in which an ink tank is integrally provided in the recording head itself is used.

Further, it is preferable to add recovery means for the recording head, preliminary auxiliary means, etc., which are provided in the present invention as a configuration of the recording apparatus, because the effects of the present invention can be further stabilized. . Specifically, these are preheated by using a capping means, a cleaning means, a pressure or suction means for the recording head, an electrothermal converter or a heating element other than this, or a combination thereof. It is also effective to perform stable recording by performing a preliminary discharge mode in which discharge is performed separately from the means and the recording.

In addition, in the above-described embodiments of the present invention, the ink is described as a liquid, but it is an ink that solidifies at room temperature or lower and softens or liquefies at room temperature, or an ink jet. In the method, the temperature of the ink itself is generally adjusted within a range of 30 ° C. or higher and 70 ° C. or lower to control the temperature of the ink so that the viscosity of the ink is within a stable ejection range. It may be in a liquid form. in addition,
Whether the temperature rise due to the thermal energy is positively used as the energy for changing the state of the ink from the solid state to the liquid state, or the ink that solidifies when left standing for the purpose of preventing the evaporation of the ink is used. In any case, thermal energy such as ink that is liquefied by applying heat energy according to a recording signal and liquid ink is ejected, or that has already started to solidify when it reaches the recording medium. The present invention can also be applied to the case of using an ink which has a property of being liquefied only after the application of
