There is.

Furthermore, if the viscosity of the ink near the 2-ejection ports is made sufficiently high, the viscosity of the ink inside the ink chamber also becomes high, which slows down the supply of ink to the vicinity of the ejection ports, leaving a problem with the recording speed.

Other than s, the means for keeping the ink inside the ink chamber in a flowable liquid state and the ink near the ejection port in a homogeneous or highly viscous liquid state includes applying heat insulating material to the structural members near the ejection port of the ink liquid chamber. (3) The heat insulating material is an optically transparent material. Ink viscosity generally depends on ink temperature, and is therefore greatly influenced by the temperature of the ink chamber components, ambient temperature, and the like. Therefore, the viscosity of the photoviscous ink can be controlled by light irradiation and heat. Hereinafter, the present invention will be explained based on examples.

ができる。The feature of "Fujitsu 1su" is that the ink viscosity at times other than when ink is ejected is mainly controlled thermally, and the ink viscosity at the time of ink ejection switching is controlled by light irradiation. Since the ink chamber is made of a material with good thermal conductivity, the area A is efficiently controlled to a constant temperature, that is, to a constant accuracy, by a heater (not shown). A heat insulating material is provided in the vicinity of the ejection opening of the ink liquid chamber, and the B area is kept at a lower temperature than the A area, that is, a high viscosity state. Therefore, ink can be smoothly supplied to the vicinity of the ejection port except when ink is ejected, and ink ejection can be reliably prevented. At this time, if the ink is pressurized, the ink can be supplied more smoothly.

Ceramics such as porous alumina, forsterite, steatite, zircon, cordierite, mullite, and zirconia, polyimide, polycarbonate, and acrylic resins are used. In particular, optically transparent materials such as 5-glass are preferable because they do not absorb the light from the light source for controlling ink ejection.

りシス体からトランス体へ異性化して粘性が上昇する。Note that a semiconductor laser or the like is used as a light source for visible light and ultraviolet light. The photoviscosity effect is a phenomenon in which a photosensitive group in a compound absorbs light of a specific wavelength and undergoes a structural change (trans φ cis photoisomerization), resulting in a change in viscosity. Generally, when a photosensitive group is irradiated with ultraviolet light, it isomerizes from a trans form to a cis form, and its viscosity decreases. In addition, under light shielding or visible light irradiation, the cis form is isomerized to the trans form and the viscosity increases.

対応するものが用いられる。At this time, the viscosity change rate is faster when visible light is irradiated than when light is shielded. There is no need for the absorption bands of translysis isomerization and cis→trans isomerization to exist in the ultraviolet region or visible region, and the absorption bands of translysis isomerization exist on the shorter 8-wavelength side than the absorption bands of cis→trans isomerization. It's fine if you do. The light source used corresponds to the wavelength range described above.

、インクが吐出することはない。インク吐出時。The ink liquid chamber component 17 is controlled to a constant temperature. The temperature sensor uses a thermistor, therefore,
Since heat is supplied from the ink chamber component 17 to the ink efficiently and with low energy, the ink temperature remains constant. The ink is maintained at a flowable temperature and is supplied to the vicinity of the ejection port 14. At this time, if the ink is pressurized, the ink can be efficiently supplied. At times other than when ink is ejected, the vicinity of the ejection port is irradiated with visible light and the ink has a high viscosity, so the ink is not ejected. When discharging ink.

It is also possible to convey and adhere up to 9. The temperature of the gas flow is preferably controlled to be constant, and more preferably controlled to the temperature of the ink chamber constituent members.

近傍へのインク供給がスムーズにできるので記録速度が
速くなる。(1) Except when ink is ejected, the ink inside the ink chamber is kept in a flowable liquid state, and the ink near the ejection port is kept in a solid or highly viscous liquid state, so ink ejection can be reliably prevented and reliability achieved. and image quality can be improved. Furthermore, since the ink can be smoothly supplied to the vicinity of the ejection ports, the recording speed becomes faster.
（２）非接触記録で両像を直接記録紙に形成することが
可能なので、信頼性が高く、耐久性に優れたコンパクト

（３）インク液室の吐出Ｉ」近傍の構成部材に断熱材を
用いているので、吐出に」近傍に可視光を照射０
する必要がなく低エネルギー駆動できる。(3) Since a heat insulating material is used for the structural members near the ejection part of the ink liquid chamber, there is no need to irradiate the vicinity of the ejection part with visible light, and low energy driving is possible.
（４）前記断熱材が光学的に透明なので、光源の光を吸
収しないため、効率的にインク吐出の制御が行えて低エ
