Publication number: 20240109330Abstract: A printing apparatus includes a liquid tank unit, a printing head, and a supply tube unit. The liquid tank unit includes first and second liquid tanks that store liquid and are arranged in parallel to each other. The printing head ejects liquid from the first and second tanks while moving in a main scanning direction. The supply tube unit includes a first supply tube connecting the first liquid tank to the printing head and includes a second supply tube coupled in parallel to the first supply tube and connecting the second liquid tank to the printing head. The second supply tube transitions from a connected tube state in which the second and first supply tubes are coupled in parallel to a single tube state by being separated from the first supply tube, passes across the first supply tube, and is connected to a connection port of the second liquid tank.Type: ApplicationFiled: September 28, 2023Publication date: April 4, 2024Inventors: Dauu TAKEDA, Hideaki MATSUMURA, Tsuyoshi SAEKI, Norio SAKURAI, Hiromasa TSUTSUMI, Shota ASADA, Taiji MARUYAMA

Patent number: 7764424Abstract: A wavelength selection unit includes a light source which emits light of at least a predetermined wavelength region, a collector lens which collects the light emitted from the light source and emits a parallel flux which is inclined relative to a light axis of an optical system of itself, a selective reflection optical system which reflects light of a predetermined wavelength region from the parallel flux selectively, and a returning optical system which returns each reflected flux reflected by the selective reflection optical system symmetrically about a reflected light axis of the selective reflection optical system. The collector lens collects a back flux which is returned by the returning optical system and which is re-reflected by the selective reflection optical system, and forms a light source image of the light source.Type: GrantFiled: May 14, 2007Date of Patent: July 27, 2010Assignee: Olympus CorporationInventors: Masato Yabe, Daisuke Yokoi, Terumasa Morita, Norio Maruyama, Yukio Eda
