Abstract: Disclosed are a document processing device and a signal transmission method thereof. The document processing device includes a processor and a printing engine. The processor is connected to the printing engine. The processor receives a document output command to generate a first differential signal. Then, the printing engine receives the first differential signal and converts the first differential signal into a first interference-free information packet. When the printing engine has already obtained the first interference-free information packet, the printing engine sends a buffer status checking signal to the processor. The document processing device uses the transmission of the first differential signal to reduce printing information errors caused by static interference, so as to achieve the purpose of improving the accuracy of printing information.

Abstract: Disclosed are a duplex document copying system and a method thereof applied to a manual operation for a document. A scanning device is connected to a processing device. The processing device stores one or more block pixel thresholds. After the scanning device obtains first scanning data and second scanning data from scanning the document, the processing device compares pixel difference information between the first scanning data and the second scanning data with the one or more block pixel thresholds to calculate a similarity between the first scanning data and the second scanning data so as to avoid repeated scans. In this way, it avoids the manual errors and outputting the repeatedly scanned document, thereby improving overall work efficiency and saving resources.

Abstract: Disclosed are a shortcut copying method for a multi-function printer and a multi-function printer using the same. After a plurality of data is input by an automatic document feeder, the multi-function printer scans first data in the plurality of data and generates a first scanning image.

Abstract: A flip cover device is provided and includes a cover, a main body and a hinge. The hinge is disposed on the main body and pivotally connected to the cover in a detachable manner for allowing the cover to pivotally unfold relative to the main body. The hinge includes a hinge body and a notch structure formed on the hinge body. The cover abuts against the main body when the cover pivotally unfolds relative to the main body to an unfolded position along a first pivoting direction. When the cover is located at the unfolded position and forced by a torque along the first pivoting direction, the cover is driven by a reaction force provided by the main body to disengage from the hinge, which prevents a damage of the cover caused by an improper and excessive pivotal movement of the cover. Besides, a related hinge is further provided.
