  • Patent number: 7826104
    Abstract: A handheld recording apparatus. A casing includes a first sidewall and a second sidewall opposite thereto. The second sidewall includes a recording through hole. A transparent positioning window is disposed in the first sidewall and corresponds to the recording through hole. A recording mechanism is movably disposed in the casing and records information via the recording through hole. A drive mechanism is disposed in the casing and is connected to the recording mechanism, moving the recording mechanism.

  • Publication number: 20100074747
    Abstract: A mini axial fan includes a fan housing and a fan unit, which is mounted in the fan housing. The fan unit has a hub with integrated blades around the periphery and integrated axles at front and back sides, and two metal pins respectively press-fitted into a respective blind hole in the free end of each of the axles for rotatably supporting the fan unit on a respective bearing in the fan housing. The fan unit is injection molded from plastics and then the metal pins are installed in the fan unit so that the precision of the metal pins is maintained and the manufacturing cost of the fan unit is reduced.

  • Patent number: 7566052
    Abstract: An automatic document feeder for electric equipment includes an input tray, a driving mechanism, and a block mechanism. The input tray has a receiving end, a discharge end, and a first path extending from the receiving end to the discharge end. The driving mechanism includes a separating-roller shaft disposed above the input tray and in proximity to the discharge end, and a separating roller sleeved fixedly on the shaft. The blocking mechanism includes a blocking member pivotable between a blocking position whereat the blocking member is disposed on the first path, and a non-blocking position whereat the blocking member is removed from the first path. A driven arm is connected to and co-rotatable with the separating-roller shaft so as to pivot the blocking member between the blocking position and the non-blocking position.

  • Publication number: 20080143045
    Abstract: A paper-feeding mechanism includes an input roller for picking up a print medium, a pinch input roller for nipping the print medium with the input roller, and a deskew shutter installed on a side of the input roller and the pinch input roller. The deskew shutter includes a flexible pad for blocking the print medium before the print medium is nipped by the input roller and the pinch input roller so as to adjust the skew print medium. The paper-feeding mechanism further includes an elastic component connected to the deskew shutter for providing an elastic force to the deskew shutter. The deskew shutter is connected to the elastic component in a rotatable manner.
