摘要： A de-skew mechanism, in an image forming device, with a correcting member disposed in a rotatable manner to the rotary shaft and turning with driving roller by a spring between them. A torque spring suppresses the turning of the correcting member to correct the skew of the medium. When conveyed, the medium will butt against the correcting member to be stopped and corrected. The medium conveying force and the force that the spring brings to the driving roller are sufficient for turning the correcting member and passing therethrough. At one time, the force that the correcting member brings to the medium will reduce to zero. As such, the medium will not be damaged by the correcting member while being conveyed.

摘要： A de-skew mechanism includes a driving shaft installed on a frame of an image forming device and driven by a motor, an active roller installed on the driving shaft and driven by the driving shaft, and an idle roller driven by the active roller for driving a medium with the active roller. A nip is formed between the active roller and the idle roller. The de-skew mechanism further includes a correcting member installed on the driving shaft in a rotatable manner and located upstream of the nip for correcting skew of the medium in a correcting position, and a restoring member connected to the correcting member for loading torque to the correcting member so as to drive the connecting member from the correcting position to a releasing position where the medium pass therethrough.

摘要： A roller module is adapted for use with an automatic document feeder, and is adapted for feeding of a document sheet therethrough. The roller module comprises a first roller, a second roller disposed adjacent to and parallel to the first roller and cooperating with the first roller to define a nip, a driven component co-rotatable with the first roller, and a driving component rotatable for abutting against and driving the driven component to rotate, thereby permitting feeding of the document sheet through the nip. During rotation of the driving component, the document sheet is brought into contact with the first and second rollers for a predetermined time period to perform skew correction before the driving component rotates the driven component.
