Application liquid reservoir

摘要

An application liquid reservoir (collector) reserves application liquid in the vicinity of an application liquid guide that is interposed between an application liquid cartridge and an applicator. The application liquid reservoir includes a cylinder having an inner hole to receive an ink guide and fins projecting from the cylinder. The fins stand parallel to each other and perpendicular to an axial direction of the inner hole at predetermined intervals, with annular application liquid reserving slots being defined between respective adjacent two fins such that the application liquid reserving slots are set to be narrower in part.
