Publication number: 20080211892Abstract: A structure for informing a state of the ink tank by a light emitting section such as LED, capable of displaying such information at a position easily visible by the user and favorably sending the emitted light both to the user and a light receiver section on the printer side without needing electric wiring which may disturb the user's visibility or manipulation. The light emitting section is separated from the display section and a light guiding section is provided between the both. A member for suitably limiting the emission of light is provided in the display section. Thereby, it is possible to dispose the display section at the best position without needing the electric wiring on the ink tank and obtain a preferable light volume suitable both for the improvement in user's visibility and the stability of the operation of the light receiving section.Type: ApplicationFiled: April 28, 2008Publication date: September 4, 2008Applicant: CANON KABUSHIKI KAISHAInventors: Yasuo Kotaki, Keisuke Matsuo, Kenji Kitabatake, Hiromasa Amma, Naoki Tashiro

Publication number: 20070291076Abstract: The present invention provides an ink jet printing apparatus and a method for controlling an ink jet printing apparatus which can shorten the stirring duration without losing any stirring effect by stirring ink at a required time to only a required level and still perform a printing operation with no image impairments. By a reciprocal movement of the carriage according to a mode during a non-printing operation excluding a print operation that is accompanied by a reciprocal movement of the carriage, ink in an ink tank is stirred. The stir mode is set according to the color of the ink in the ink tank mounted on the carriage.Type: ApplicationFiled: June 13, 2007Publication date: December 20, 2007Applicant: CANON KABUSHIKI KAISHAInventors: Satoshi Seki, Hitoshi Nishikori, Daisaku Ide, Yoshito Mizoguchi, Yasuo Kotaki, Tetsuya Ohashi, Ryoji Inoue

Patent number: 4988244Abstract: A machine includes a pair of spaced supports, one of which may mount an operator such as a tool in a spindle and the other of which may mount an object such as a workpiece. The spaced platforms are joined by six powered and extensible legs joined to the respective platforms by universal joints. The length of the legs is individually manipulated to vary the position of the platforms and therefore the object and operator relative to each other in six axes. The powered legs may be hydraulic cylinders or recirculating ball screw driven. The distance between the spaced platforms may be measured by separate instrument arms which join the platforms. The instrument arms may use a digital position device to measure the extension and contraction of the instrument arms or may use a laser interferometer for that purpose. The changes in the instrument arm's lengths may be used to generate signals which are used to control the extension and contraction of the powered legs.Type: GrantFiled: August 23, 1990Date of Patent: January 29, 1991Assignee: Kearney & TreckerInventors: Paul C. Sheldon, Edward E. Kirkham
