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.
摘要翻译：即使通过单个传感器执行检测，即使检测到的S / N比低，检测出液体容器的存在/不存在以及容器中的液面的精度也提高，检测结果可以彼此歧视。为此，在光学棱镜的底面的中心设有凹面多面体，以减少在光学棱镜的底面上反射的光并返回感光体。此外，具有二次表面的反射曲面，例如，球形表面或抛物面，设置在墨水罐的底表面上，用于反射由发光装置和感光体组成的光学单元发出的光。由此，即使在光学单元的配置角度或位置偏离一定程度的情况下，也可以接收足够量的感光体的光量，能够精确地检测墨水的存在/不存在以及 /或墨水罐的存在/不存在。

摘要： A container for containing liquid to be ejected. The container includes a negative pressure producing member accommodating chamber for accommodating a negative pressure producing member. The negative pressure producing member accommodating chamber is provided with an air vent for fluid communication with ambience and a liquid supply portion for supplying the liquid to a liquid ejecting head having ejection outlets. The container also includes a liquid containing chamber which is substantially hermetically sealed except for a fluid communication path through which the liquid containing chamber is in fluid communication with the negative pressure producing member accommodating chamber. A partition is provided for separating the negative pressure producing member accommodating chamber and the liquid containing chamber. The partition is provided with an ambience introduction path for introducing the ambience into the liquid containing chamber from the negative pressure producing member accommodating chamber. The ambience introduction path forms a capillary force generating portion. The capillary force which is produced by the capillary force generating portion satisfies a relationship between that capillary force and potential head differences, head losses, and other capillary forces in the container.

摘要： A capped liquid container comprises a liquid container for retaining liquid, having a supply opening formed for supplying the liquid to the recording devices of an ink jet recording apparatus, and a cap fixed to the liquid container for closing the supply opening, the cap being removed from the liquid container by rotating the cap. This cap is formed by a rigid member and an elastic member, and the elastic member is provided with a first engagement portion, while a second engagement portion is formed on the edge circumference of the supply opening to engage with the first engagement portion. Then, the first engagement portion and the second engagement portion are sealingly pressed together, and at the same time, a part of the rigid member of the cap is fixed to the liquid container. With the structure thus arranged, the contact surface between the first and second engagement portions produces the sealing effect, hence making it possible to fabricate a capped liquid container having a high water tightness and air tightness. Further when the liquid container is unsealed, it is easy to open the liquid container without causing liquid to spread externally with the provision of the rigid member to the cap which prevents the container from being passed inwardly when being unsealed.
摘要翻译：封盖的液体容器包括用于保持液体的液体容器，具有用于将液体供应到喷墨记录装置的记录装置的供应开口，以及固定到液体容器以关闭供应开口的盖子，盖子被移除通过旋转盖从液体容器。该帽由刚性构件和弹性构件形成，并且弹性构件设置有第一接合部，而在供给口的边缘周缘上形成第二接合部，以与第一接合部接合。然后，第一接合部和第二接合部被密封地压在一起，同时将帽的刚性部件的一部分固定在液体容器上。通过如此布置的结构，第一和第二接合部分之间的接触表面产生密封效果，因此可以制造具有高防水性和气密性的封盖液体容器。此外，当液体容器开封时，容易打开液体容器而不会使液体从外部扩张，并将刚性构件设置到盖上，从而防止容器在开封时向内通过。

Further, the steps to be created between the supply flow path and the supply port is buried by the bonding agent forced out from the bonding face of the recording element base plate and the supporting member. With the structure thus arranged, the ink jet recording head is capable of optimizing the discharge characteristics of recording liquid and the supply characteristics thereof, as well as the positioning precision of a recording element base plate to a supporting member.

摘要： The present invention provides a liquid housing container that enables an increase in the channel cross section of a connection portion of a liquid channel that allows a liquid housing chamber to communicate with an exterior, allowing pressure loss to be minimized. A supply needle 107 is pushed into a liquid housing container to move, to an open position, a valve 102A. With the valve 102A remaining in the open position, the supply needle 107 is pushed back and held separate from the valve 102A. Subsequently, the supply needle 107 is pushed into the liquid container again to move the valve 102A to a closed position. Even when the supply needle 107 is removed from the liquid housing container, the valve 102A is held in the closed position.

摘要： A liquid discharge apparatus for producing a probe carrier, having a configuration capable of supplying a discharge unit with plural probe solutions without increasing the dimensions of the apparatus, as well as a method and apparatus for producing the probe carrier utilizing such liquid discharge apparatus. The arrangement pitch of the supply openings to liquid holding portions from plural liquid discharging portions (which are provided in the liquid discharge apparatus and respectively correspond to the plural probes) is set to be larger than the arrangement pitch of nozzle openings, thereby increasing the freedom in designing the position and capacity of the liquid holding portions for holding the probe solutions.
