  • Patent number: 9169963
    Abstract: A stand device includes a pedestal having a base and a cap, a support, and a pulling member, wherein a receiving space is formed between the base and the cap. The support includes a connecting member and a positioning member. The connecting member includes a contact portion and a connect portion extended from the contact portion, and the contact portion is disposed at an outer surface of the cap. The positioning member includes a restraining portion and a fixing portion extended from the restraining portion and passing through an opening of the cap for connecting to the connecting member, and the restraining portion is disposed at an inner surface of the cap. When the support is rotated around the pedestal, the fixing portion is moved within the opening, and when the fixing portion is moved against the edge of the opening, the support may be restrained rotating around the pedestal.

  • Publication number: 20130242471
    Abstract: A forward lid-lift device assembled to a counteraction member of an electronic apparatus includes a main lid and a turning lid. The main lid includes a first rotary shaft connected with the counteraction member, and an engaging end fastened at the end of the electronic apparatus opposite to the first rotary shaft. The turning lid includes a second rotary shaft connected to the main lid, a poking end at an end of the second rotary shaft, and a pushing member at the other end of the second rotary shaft. When the pushing member rotates from a start point to an end point along a second turning path in a first direction, the interference between a first turning path of the counteraction member and the second turning path is increased gradually and the main lid and the turning lid are both turned in the same direction to complete lid-lift action.

  • Patent number: 7922306
    Abstract: A print ink transport mechanism includes a first ink pipe for transporting a first colored ink, and a second ink pipe for transporting a second colored ink, a rotary module including a first protruding component with a first cavity disposed in a position corresponding to the first ink pipe, and a drive means connected to the rotary module for driving the rotary module. When the drive means drives the rotary module to rotate to a first position, the first protruding component presses the second ink pipe, and the first ink pipe passes through the cavity on the first protruding component, so that the second ink pipe is unable to transport the second colored ink and the first ink pipe is able to transport the first colored ink.

  • Patent number: 7748823
    Abstract: The inkjet maintenance device cleans a printhead with a wiper on a first platform and cleans the wiper with a scraper on a second platform. Two slits with different shapes disposed on a base of the maintenance device allow the first platform and the second platform to slide respectively. In a single stroke of maintenance, the first platform and the second platform are simultaneously pushed substantially horizontally while the first platform further moves substantially vertically relative to the second platform, which allows the scraper on the second platform to clean the wiper of the first platform in the same stroke when the wiper cleans the printhead.

  • Publication number: 20090309937
    Abstract: An ink storage module includes an ink flow control device and an air chamber. The ink storage module is accessible to an ink tank and an air-extracting device. The ink flow control device includes an ink storage chamber and a pressure control mechanism. The ink storage chamber is used for receiving and storing ink conveyed from the ink tank. The pressure control mechanism is connected to the ink storage chamber for controlling the connection of an external pressure to the ink storage chamber. The air chamber is disposed at a side of the ink flow control device and is accessible to the ink storage chamber. The air chamber is used for exhausting air extracted by the air-extracting device. When the pressure control mechanism controls the ink storage chamber to cut off the external pressure, the air-extracting device drives ink to flow from the ink tank to the ink storage chamber.
