摘要： An inexpensive ink tank having an ink remaining amount detection section which can be used with ink of any color is disclosed. An optical ink detection section formed from a light transmitting material has an inclined interface and is formed integrally with the ink tank. Incident light from a light source is refracted, when ink is present in the ink tank, at the interface to make refraction light and does not emerge to a visual observation portion. When no ink is present, the incident light is totally reflected by the interface to make total reflection light, which can be visually observed at the visual observation portion. A roughened face is formed at the visual observation portion so that light emerging to the visual observation portion may be scattered to facilitate visual observation.

摘要： The present invention provides an inkjet recording head cartridge and an inkjet recording apparatus that have a simple structure and high reliability. Since individual flow passages in which ink emission orifices are formed are communicated directly with a rectangular ink supply chamber, it is prevented that a bubble of such a size as to cause printing defects rises through an ink supply chamber and blocks the individual flow passages. Also, since ink heated within the ink supply chamber is moved upward to the ink tank chamber by convection and grows an air lump sealed beforehand, it is prevented that a bubble will grow in the ink supply chamber. Furthermore, by allocating a large cross-sectional area to the ink supply chamber, it is prevented that meniscus oscillation of the ink emission orifices is amplified by pressure oscillation caused by ink emission and causes a printing defect. Therefore, reliable printing can be performed with a simple construction.

摘要： An ejection element driving device includes a signal selection section and a signal selection control section. The signal selection section selects a drive signal to be applied to each ejection element from among drive signals including a liquid droplet ejection signal for ejecting a liquid droplet from the ejection element and a viscosity increase suppression signal for suppressing increase in a viscosity of liquid to be ejected by each ejection element. The signal selection control section refers to a predetermined parameter for any of the ejection elements for which the liquid droplet ejection signal is not selected. The signal selection control section exercises control over whether or not the signal selection section selects the viscosity increase suppression signal for the ejection elements for which the liquid droplet ejection signal is not selected, at each ejection cycle.

摘要： The present invention provides a liquid jet printing head, a method of manufacturing the same, and a liquid jet printing apparatus, which allow stable, high speed, and continuous printing. A liquid jet printing head provides an inflow of liquid from an inlet to a common chamber, then along with the surface of heating elements of a heating element substrate and with a wall of a housing to separate channels. Liquid drops will be ejected by heating the heating elements. Since liquid may flow linearly from the inlet to the separate channels in accordance with the present invention, smooth flow promotes evacuation of bubbles through a nozzle, while cooling the heating element substrate with liquid flowing along with the substrate. The present invention provides thereby stable printing with high speed, continuous ejection (printing) of liquid drops.
