    • A casing body of an ink cartridge includes a first chamber allowing atmospheric air to enter therein, and a second chamber that stores ink. A lid within the second chamber moves vertically while partitioning the second chamber into a first space above the lid and a second space below the lid for storing ink. A gap between an outer periphery of the lid and an inner periphery of the second chamber allows a meniscus of ink to form therebetween. A partition is provided at an upper end of the second chamber to partition the first and second chambers. The partition includes a through hole at a portion which is away from the inner periphery of the second chamber, to allow the atmospheric air to enter the second chamber. An elastic member in the second chamber urges the lid upwards to maintain the second space of the second chamber at a negative pressure.
    • 墨盒的壳体包括允许大气进入其中的第一室和存储墨的第二室。 第二腔室内的盖板垂直移动,同时将第二腔室分隔成盖子上方的第一空间,并且在盖子的下面用于储存墨水的第二空间。 盖的外周和第二室的内周之间的间隙允许在其间形成墨水弯月面。 在所述第二室的上端设置隔板以分隔所述第一和第二室。 隔板包括在远离第二室的内周的部分处的通孔,以允许大气进入第二室。 第二室中的弹性构件向上推动盖子以将第二腔室的第二空间维持在负压。

    • A printer and an ink tank for the printer capable of precisely detecting that ink has run out in a foam type ink tank. The ink chamber and an ink passage are formed in this order between the foam containing portion and the ink outlet of a foam-type ink tank. A first filter is installed between the foam containing portion and the ink passage and used to pass bubbles therethrough, whereas a second filter having a pore diameter smaller than the pore diameter of the first filter is installed between the ink chamber and the ink passage. A rectangular prism for detecting an ink end is formed on the side of the ink chamber. When the reflective surface of the rectangular prism is exposed from an ink liquid level as bubbles are gathered in the ink chamber with ink that is running short, light is reflected from the reflective surfaces and is detected by a reflection type optical sensor on the ink-jet printer side, so that the ink end can be determined. In a case where the capacity of the ink chamber is set sufficiently smaller, the ink end is detectable at a point of time when the ink has substantially run out.
    • 用于打印机的打印机和墨水罐能够精确地检测在泡沫型墨水盒中的墨水已经耗尽。 墨水室和墨水通道在泡沫容纳部分和泡沫型墨水盒的墨水出口之间依次形成。 第一过滤器安装在泡沫容纳部分和油墨通道之间并用于通过气泡,而具有小于第一过滤器孔径的孔径的第二过滤器安装在油墨室和油墨通道之间。 用于检测墨水端的矩形棱镜形成在墨水室的一侧。 当由于气泡聚集在油墨室中时,由于墨水长时间短而使矩形棱镜的反射表面从油墨液面暴露出来,所以从反射表面反射光并被反射型光学传感器检测到, 喷墨打印机侧,从而可以确定墨水端。 在墨水室的容量设定得足够小的情况下,在墨水基本上耗尽的时间点可以检测墨水端。

    • A printer includes a cutting apparatus with a shield that protects the cutting part of a cutter blade in the apparatus. A fixed blade is supported so that the fixed blade can be moved by pressure by a compression coil spring upon a fixed blade supporting frame attached to a body frame so that the fixed blade supporting frame can be opened or closed. A blade cover for protecting the cutting part of the fixed blade is fixed to the fixed blade supporting frame. When each fitting between fitting parts of the fixed blade and touching parts of a cutter frame is released in a state in which the fixed blade supporting frame is open, a part or the whole of the cutting part of the fixed blade is shielded by the shielding part of the blade cover.
