Abstract: 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.

The pressing block is disposed on one side of the film opposite to the scanning module and presses against the film for reducing the height of the paper track above the scanning module. When the paper sheet is passes over the scanning module, the paper pressing device presses the paper sheet for maintaining the paper sheet flat while being scanned.

Abstract: An automatic document feeder includes a first path extending from a feeding tray to a scanning module, a second path extending from the scanning module to a reversing roller unit, and a third path extending from the reversing roller unit to an intermediate portion of the first path. A document is moved from the feeding tray onto the reversing roller unit via the first and second paths for a first scanning. Just before the document is moved through the second path, the reversing roller unit is driven to allow the document to move therethrough. Subsequently, the document is reversed on the reversing roller unit to move through a looped passage defined by the third path, a portion of the first path downstream of the intermediate portion, and the second path for a second scanning. The reversing roller unit is operable to allow two opposite edges of the document to move thereon in different directions.

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.

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.
