摘要： The invention is prevent drawbacks resulting from the bubble generated at the downstream side of the filter, while minimizing the waste in the ink. The recording head (201) has a sub tank (201b) for storing ink supplied from the exterior, and a liquid chamber (201f) storing the ink supplied from the sub tank (201b) and supplying ink directly to a nozzle (201g) for ink discharge. A filter (201c) is provided between the sub tank (201b) and the liquid chamber (201f). The liquid chamber (201f) holds ink of a predetermined amount in such a manner that the ink therein is separated by gas from the filter (201c).

摘要： A cartridge (3) is detachably mountable on holding means of an ink jet recording apparatus, which is freely reciprocating to scan for recording by discharging ink to a recording medium, and provided with a recording head for discharging ink from plural nozzles formed in parallel on the lower face of the carriage (1) main body facing the recording medium. For the front face (42) of the cartridge main body, an electrical connection portion having electrodes (27) on the cartridge side is provided and electrically connected with electrodes of the holding means on holding means side, and for the rear face (43) being opposite to the front face, an ink connection portion having supply means connected thereto is provided to supply ink to the recording head from the main tank installed on the main body of the ink jet recording apparatus. With the cartridge thus structured, the force exerted for connecting the supply means does not weaken the force exerted on the holding means for positioning, and does not produce any unfavorable effect, either, on the precision with which the cartridge is positioned with respect to the holding means.

摘要： Precision of detecting existence/non-existence of a liquid container and a liquid level in the container is improved even if the detection is performed by a single sensor, or even if the S/N ratio of the detection is low, the detected results can be discriminated from one another. For this, a concave polyhedron is provided in the center of the bottom surface of an optical prism in order to reduce the amount of light reflected on the bottom surface of the optical prism and returned to a photoreceptor. Moreover, a reflection curved surface having a quadratic surface e.g. spherical surface or paraboloid, is provided on the bottom surface of an ink tank, for reflecting light emitted by an optical unit consisting of a light emission device and a photoreceptor. By virtue of this, even in a case where an arrangement angle or position of the optical unit is deviated to some extent, sufficient amount of light for the photoreceptor can be received, making it possible to accurately detect existence/non-existence of ink and/or existence/non-existence of an ink tank.
