Abstract
A liquid level detector includes an electrode portion including a substrate, a first electrode plate separated a predetermined distance from the substrate, a hollow second electrode plate extending from the substrate to the first electrode plate and having an opening corresponding to the outer circumferential surface of the first electrode plate, and a liquid level detecting portion which detects the presence of the liquid at the detection position from a change in electrostatic capacity measured by the first and second electrode plates. Thus, the level of liquid stored in the container can be detected from outside of the container in a non-contact manner, simplifying the structure of the apparatus and preventing the generation of an error in measuring the liquid level due to ink adhering to the container.
