ABSTRACT:
A device for detecting the presence or absence of a liquid, which is installed on an ink-jet recording apparatus, is configured to determine the presence or absence of ink in the ink flow path by detecting the reflection of light from a light transmission portion by irradiating light thereon. The light transmission portion is formed on at least a part of the ink path wall that forms the ink flow path for supplying ink to the recording head. As a result, it becomes possible for responding to consumer demands of designing a smaller version of the ink tank, a cost effective production thereof, and the like in addition to provide images with excellent image qualities.
