  • Patent number: 7111931
    Abstract: An ink tank is provided which can apply an optimum negative pressure stably by a valve of a simple structure. To this end, the ink tank of this invention has a valve and a damper section installed in an ink flow path. The valve deforms when the negative pressure in the ink supply port is greater than a predetermined level, to temporarily open the ink flow path to introduce ink from the ink accommodation portion to the ink supply port. The damper section is installed between and communicates to the ink supply port and the valve in the ink flow path. The damper section is formed of a resilient member more easily deformed than the valve and applies a negative pressure to the interior of the ink supply port by an elastic recovery force of the resilient member.

  • Publication number: 20060082625
    Abstract: 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.

  • Patent number: 6997548
    Abstract: A recording head cartridge in which ink tanks include a removal preventing pawl which is provided at a rear surface of an ink container and engages with a tank holder, and a latch lever which is provided at a front surface of the ink container and which has a latch pawl engaging with the tank holder. The height of a rear wall and a side surface of the tank holder are set to be lower than corresponding heights of the ink tank. During removal, the container abuts the upper end of the peripheral wall of the tank holder an dis rotated about this upper end so that a part of the side surface of the container is protruded externally of the holder. Accordingly, a space required to remove the container form the tank holder is placed external of the peripheral wall of the tank holder. Thus, removal space ordinarily wasted by a conventional tank holder can be eliminated.

  • Publication number: 20060026376
    Abstract: Storing image data for a menu in a compound image file. Image data for a menu of media files is retrieved and efficiently stored in the compound image file. A media player accesses the compound image file to obtain and display relevant images in a menu. The invention reduces the quantity of file operations needed to render the menu and thus reduces the time needed to display the menu as perceived by a user. As a result, the invention enhances the user experience with the media player.
