Publication number: 20100003060Abstract: A paper cutting device for cutting sheet material from the lengthwise edges of the material toward the middle comprising a stationary blade and first and second movable blades with the sheet material placed between the stationary blade and the first and second movable blades. The paper cutting device enables the spacing between the stationary blade and the first and second movable blades to be opened by moving the stationary blade frame and the movable blade frame relative to each other. The first movable blade and second movable blade are supported on a first stud and second stud, respectively, near the distal ends of the edge of the blade part of the stationary blade so that the paths of the blade tips overlap when cutting the sheet material. The movable blade drive mechanism drives the first movable blade and second movable blade with the first movable blade leading and the second movable blade following.Type: ApplicationFiled: September 14, 2009Publication date: January 7, 2010Inventors: YUKIHIRO HANAOKA, Hiroyuki Nakayama

Publication number: 20090160888Abstract: An ink tank of the foam type which is provided with a detected portion capable of exactly and surely detecting the amount of ink used by the printer or remaining in the ink tank. The ink tank includes a sub ink chamber that is disposed or formed between a main ink chamber and an ink outlet of an ink tank of a foam type. When an amount of air flowing into the sub ink chamber increases, one or more reflecting surfaces of a right-angled prism, which function as ink interfaces, resume their original function of reflecting surfaces, thereby enabling the detection of an ink end. Air bubbles having entered the sub ink chamber are surely led onto the one or more reflecting surfaces by a bubble storage part. At an ink passage having a narrow width, which is defined by the one or more reflecting surfaces, air bubbles are pressed against the one or more reflecting surfaces to be put to a crushed state and in surface contact with the latter.Type: ApplicationFiled: February 20, 2009Publication date: June 25, 2009Applicant: Seiko Epson CorporationInventors: Atsushi Nishioka, Yukihiro Hanaoka, Manabu Yamada

Publication number: 20070296777Abstract: A multicolor-use ink cartridge has obverse surface-side ink chambers and formed on an obverse surface side of a horizontal plate portion of a rigid plastic plate and reverse surface-side ink chambers and formed on a reverse surface side thereof. Since these ink chambers are arranged in a breadthwise direction so as to be staggered in a mutually overlapping state with the horizontal plate portion interposed therebetween, it is possible to make small the dimension in a direction in which the ink chambers are arranged. The respective ink chambers are formed by joining flat portions of three-dimensionally molded flexible plastic films to obverse surface-side recesses formed on the obverse surface of the horizontal plate portion and reverse surface-side recesses formed on the reverse surface thereof, respectively. Therefore, it is possible to form ink chambers having high sealability.Type: ApplicationFiled: August 15, 2007Publication date: December 27, 2007Inventor: Yukihiro Hanaoka

Patent number: 6966642Abstract: A printer and an ink tank for the printer capable of precisely detecting that ink has run out in a foam type ink tank. The ink chamber and an ink passage are formed in this order between the foam containing portion and the ink outlet of a foam-type ink tank. A first filter is installed between the foam containing portion and the ink passage and used to pass bubbles therethrough, whereas a second filter having a pore diameter smaller than the pore diameter of the first filter is installed between the ink chamber and the ink passage. A rectangular prism for detecting an ink end is formed on the side of the ink chamber. When the reflective surface of the rectangular prism is exposed from an ink liquid level as bubbles are gathered in the ink chamber with ink that is running short, light is reflected from the reflective surfaces and is detected by a reflection type optical sensor on the ink-jet printer side, so that the ink end can be determined.Type: GrantFiled: April 29, 2004Date of Patent: November 22, 2005Assignee: Seiko Epson CorporationInventors: Yukihiro Hanaoka, Koji Yamada, Manabu Yamada
