  • Publication number: 20140178083
    Abstract: A detection device for detecting a state of a waste toner container comprises an optical sensor and an actuation member. The optical sensor comprises an emitting unit emitting an optical signal and a receiving unit receiving the optical signal. A space is provided between the emitting and receiving units, and the optical signal travels along an optical path from the emitting unit to the receiving unit. The actuation member is movably disposed between the emitting and receiving units. The actuation member in a first position interrupts the optical path of the optical signal; and the actuation member is moved by the waste toner container to a second position when at least a part of the waste toner container is placed in the space. The actuation member in the second position allows a passage of the optical signal. An image forming apparatus using such a detection device is also provided.

  • Patent number: 8757611
    Abstract: A sheet-feeding apparatus includes a passage, a sheet-feeding roller disposed at an entrance of the passage, and a paper pressing mechanism including a paper pressing device and a driving mechanism. The driving mechanism drives the paper pressing device to move towards and away from the sheet-feeding roller. The driving mechanism includes a power source, a rotating shaft connected to the power source, and an arm attached to the rotating shaft. As the rotating shaft rotates in a first direction, the arm actuates the paper pressing device to move away from the sheet-feeding roller. As the rotating shaft rotates in a second direction, the arm releases the paper pressing device, so the paper pressing device moves towards the sheet-feeding roller and presses a paper sheet upon the sheet-feeding roller.

  • Patent number: 8683649
    Abstract: In an automatically closing hinge, a first body and a second body are mounted on a fixed shaft, and axial and radial moving members are adjacently disposed inside the fixed shaft. The second body pivoting rearward in relation to the first body enables an inward radial movement of the radial moving member, and during the inward radial movement the radial moving member causes a forward axial movement of the axial moving member. An energy storing member in the fixed shaft is configured to store energy during the forward axial movement of the axial moving member and to release energy for driving the axial moving member to make a reverse axial movement. During the reverse axial movement the axial moving member pushes the radial moving member to make an outward radial movement. The radial moving member during such outward radial movement drives the second body to pivot forward.

  • Patent number: 8559069
    Abstract: A sheet-fed scanner includes a housing, a scan assembly carrier, a scan assembly and a bent linking member. The scan assembly carrier is movably disposed in the housing. The scan assembly mounted in the scan assembly carrier scans a side of an original sheet in a main scan direction. The bent linking member disposed between the housing and the scan assembly carrier includes a first section and a second section. The first section extends transversally in relation to the main scan direction and interconnecting two opposed ends of the scan assembly carrier. The second section, connected with the first section, forms an angle with the first section. As one of two opposed ends of the scan assembly carrier is pushed towards the housing in a direction, the bent linking member urges the other end to move in the same direction.

  • Patent number: 8538292
    Abstract: An image forming apparatus includes a case, a photosensitive drum, a developing cartridge, a supporting member set, a force-exerting member set and a resilient member. The photosensitive drum forms a toner image. The developing cartridge, movably disposed within the case, includes a developing tank and a developing roller. The developing roller, mounted on the developing tank and positioned opposite the photosensitive drum, transfers toners to the photosensitive drum. The supporting member set is disposed on an inner wall of the case. The force-exerting member set, disposed on an outer wall of the developing tank, interacts with the supporting member set to maintain steady contact pressure between the developing roller and the photosensitive drum. The resilient member, disposed between the developing tank and the case, provides a restoring force for counteracting a weight of the developing tank and urging the developing roller towards the photosensitive drum.

  • Patent number: 8395827
    Abstract: A scanner includes a platen assembly, a sheet feeder and a scanning module. The platen assembly and the sheet feeder are combined together to form a non-linear paper path. The paper path has a scan region. The sheet feeder includes a feeding mechanism, a transporting mechanism and a discharging mechanism. The feeding mechanism feeds a document into the paper path. The transporting mechanism transports the document from the feeding mechanism to the scan region. The document is transported past the scan region in a direction substantially parallel to a scan plane in the scan region. The discharging mechanism transports the document out of the paper path from the scan region. The scanning module movably disposed in the platen assembly acquires an image of the document transported past the scan region.
