  • Patent number: 9446919
    Abstract: A push-pull latch assembly for a detachable media pick mechanism. The latch assembly comprises a handle that is slidably and axially insertable into a handle base which is mounted to the pick mechanism housing. The handle base includes a pair of cantilevered, opposed latched arms having opposed catches for engagement with a groove positioned adjacent to a free end of a cantilevered drive shaft for the pick mechanism. The handle includes triangular rails having inner and outer ramps used to separate the opposed latch arms. The outer ramp separates the latch arms when the handle is inserted into the handle base. The inner ramp separates the latch arms during removal of the pick mechanism from the drive shaft. An axial pushing force engages the latch assembly to the groove and an axial pulling force disengages the latch assembly from the groove allowing for pick assembly removal.

  • Patent number: 8888090
    Abstract: A switchable note-picking device (1) used at a note inlet of a note processing device comprises a note-bearing platform (17), a note-picking mechanism (13) for picking notes on the note-bearing platform (17) and a note-classifying mechanism (11) for classifying the picked notes. The note-classifying mechanism (11) comprises a note-classifying shaft (112) and a note-classifying wheel fixed on the note-classifying shaft (112). The switchable note-picking device (1) further comprises a driving component (15) for driving the note-picking mechanism (13) hidden below the note-bearing platform (17) to be exposed out of the note-bearing platform (17) and contact with the notes. By the driving component (15), the note-picking mechanism (13) is exposed out of the note-bearing platform (17) when picking notes and hidden below the note-bearing platform (17) when being free from picking notes, so that the switchable note-picking device (1) can stop deposition and deposit a specified amount of notes.

  • Publication number: 20140306400
    Abstract: A feeding apparatus includes a pickup roller arranged to pick and feed a medium downstream along a conveying path, a separating roller arranged downstream to the pickup roller for advancing the medium downstream, a brake roller arranged opposite to the separating roller, and a pressing structure arranged opposite to the pickup roller and operable to swing toward or away from the pickup roller according to the rotating direction of the brake roller. When the brake roller rotates for feeding mediums downstream, the pressing structure moves toward the pickup roller and applies a normal force required for picking the medium. But when the brake roller stops rotating downstream because multiple mediums are fed between the brake roller and the separating roller, the pressing structure moves away from the pickup roller and stops applying normal force, so as to control the medium-picking process.

    Abstract: A removable media dam for a media input tray. The removable media dam is mountable in a front wall of the media tray and may contain one or more rollers for feeding media from the media input tray. The removable media dam includes a separator roll positioner for angularly rotating a separator roll between a retracted position and an extended position to adjust the height of the separator roll with respect to a media contact surface thereby varying the media sheet separation force applied by the separator roll to media sheets being fed from the media tray. In one form, the removable media dam is mountable by a user without the use of tools.

  • Patent number: 8807555
    Abstract: An automatic document feeder includes an upper cover, a pick-up arm, a restriction element, and a document stopper. The pick-up arm is movable between a first position and a second position. A rotating shaft of the restriction element is pivotally coupled to the pick-up arm. A rotating shaft of the document stopper is pivotally coupled to the upper cover. Moreover, the rotating shaft of the restriction element and the rotating shaft of the document stopper are not in parallel with each other. When the pick-up arm is located at the first position, a swinging action of the document stopper is limited by the restriction element. When the pick-up arm is located at the second position, the swinging action of the document stopper is no longer limited by the restriction element, so that the document stopper can be freely swung.
