    • A liquid container which can precisely detects existence/absence of residual liquid at a low cost, a cartridge including the liquid container, and a printing apparatus using the cartridge. The lengthwise direction of a triangular prism provided on the bottom of the ink tank is along a direction of print medium conveyance in the printing apparatus, such that when an ink-jet head cartridge holding the ink tank is attached to the printing apparatus for performing printing, light emitted from an optical unit of the printing apparatus is precisely captured by the prism. Further, if two ink-jet head cartridges are mounted on the printing apparatus, the first and second ink-jet head cartridges are set in positions shifted from each other by a length shorter than the length in the lengthwise direction of the prism, such that the light emitted from the optical unit reaches the prisms provided in the ink tanks of the first and second ink-jet head cartridges.
    • 可以以低成本精确地检测残留液体的存在/不存在的液体容器,包括液体容器的药筒和使用该药筒的打印装置。 设置在墨盒底部的三角形棱镜的长度方向是沿着打印设备中的打印介质输送方向,使得当将保持墨水盒的喷墨头盒安装到用于进行打印的打印设备 从打印装置的光学单元发射的光被棱镜精确地捕获。 此外,如果将两个喷墨头盒安装在打印装置上,则将第一和第二喷墨头盒设置在彼此偏移比长度方向长度短的位置,使得 从光学单元发射的光到达设置在第一和第二喷墨头盒的墨盒中的棱镜。
