  • Patent number: 11761474
    Abstract: A control cable connection structure includes a long, narrow casing, a casing end, a cable end and a slider. An end portion of a first conduit is anchored at one end portion, in a length direction, of the casing. An end portion of a second conduit is anchored at the casing end. The casing end is superposed and assembled with the casing in a radial direction of the second conduit. The cable end is attached to an end portion of a second inner cord. An end portion of a first inner cord is anchored at the slider. The slider is supported at the casing to be slidable in the length direction thereof. In the assembled state, the cable end is engaged with the slider at an opposite side from a side at which the second conduit is disposed, and the second inner cord is connected with the slider.

  • Patent number: 7147309
    Abstract: An ink cartridge is provided with an ink accommodating section for containing ink, an ink supplying part for supplying ink contained in the ink accommodating section to an inkjet type recording apparatus by inserting an ink supplying needle provided at a lower part of the inkjet type recording apparatus, and an atmospheric valve, which seals a communicating hole in order that the ink accommodating section and the atmosphere communicate, while opening a communicating hole, which allows the ink accommodating section to communicates with the atmosphere, by moving perpendicular to a direction in which the ink cartridge is inserted into the inkjet type recording apparatus by being pushed up by a contact member.

  • Patent number: 7125108
    Abstract: A liquid cartridge is provided that supplies liquid to a liquid ejecting apparatus by being mounted in the liquid ejecting apparatus. The liquid cartridge includes a cartridge body having a side face in which an opening is formed; and a flexible film for forming an ink accommodating chamber that is a closed space for accommodating the liquid, with the cartridge body by covering the opening of the cartridge body. The flexible film is caused to deform toward the ink accommodating chamber by atmospheric pressure that acts on the flexible film when the liquid cartridge is got out from a vacuum bag in which the liquid cartridge is packaged, thereby increasing the pressure in the ink accommodating chamber.
