摘要： Multiple grooves are formed along an inclination face of a prism-like part. A pitch of the grooves is smaller than the wavelength of light, specifically infrared light, used as a light source for detecting an ink amount. When sufficient amount of contained ink is consumed to expose the prism-like part, ink on the inclination face is held in the grooves due to their capillary force. At this time, if an amount of the ink exceeds the capacities of the grooves, no capillary force acts on the excessive ink. Accordingly, the excessive ink becomes an ink pool and slides down to an ink surface. Since the face provided with the grooves at the pitch smaller than the wavelength of the detection light source serves as a plane face optically, detection with high reliability is made possible.
摘要翻译：沿棱镜状部分的倾斜面形成多个凹槽。凹槽的间距小于用作检测墨量的光源的光的波长，特别是红外光。当足够量的所含的墨水被消耗以露出棱镜状部分时，由于其毛细管力，倾斜面上的墨水被保持在凹槽中。此时，如果油墨的量超过槽的容量，则不会对过量的油墨产生毛细作用力。因此，过量的墨水变成墨水池并向下滑动到墨水表面。由于以比检测光源的波长小的间距设置凹槽的面用作光学平面，因此可以高可靠性的检测成为可能。
