Abstract: A sheet separating mechanism of an auto document feeding (ADF) device includes an ADF roller, two separating rollers and one pressing element. The pressing element is disposed between the separating rollers to form an assembly, and the pressing element and the separating rollers contact the ADF roller. A sheet is fed under the cooperation of the assembly and the ADF roller. The separating rollers rotate to provide a friction force for sheet separating. The pressing element presses a surface of the sheet such that the sheet may be smoothly fed without bulginess.

Abstract: An auto-lock mechanism to be mounted on an image input/output device includes a first swingable element and a second swingable element. When the image input/output device is not slantwise and an upper cover of the device is opened, one of the first and second swingable elements swings but does not hook the other of the first and second elements. When the image input/output device is slantwise, both of the first and second swingable elements simultaneously swing, approach and hook each other such that the upper cover remains closed and is free from detachment to hurt a user.

Abstract: In a digital copying apparatus with a smart fitting function, a scanning unit acquires a document image of a document to obtain a document image signal, a sheet size sensor senses a to-be-printed sheet placed in a sheet storage module and outputs a sheet size signal, and a control processing unit receives the document image signal and the sheet size signal and selectively executes auto-cropping, rotating, and/or scaling procedures according to the document image signal and the sheet size signal such that the processed document image signal fits to the sheet size signal. Then, a printing unit receives a printing signal coming from the control processing unit and prints a printed image on the to-be-printed sheet.

Abstract: In a printing device capable of increasing a printing speed, a sheet-feeding mechanism selectively feeds to-be-printed sheets placed in a longitudinal tray and a transversal tray. A memory stores a transversal maximum printing dimension corresponding to a printing unit. A processor receives a printing signal containing first and second dimensions. The processor judges whether or not a maximum of the first dimension and the second dimension is smaller than or equal to the transversal maximum printing dimension. If yes, the processor enables the sheet-feeding mechanism to feed the to-be-printed sheet placed in the transversal tray. The processor further judges whether or not the first dimension is smaller than the second dimension. If yes, the processor rotates a printing content corresponding to the printing signal by 90 degrees and then outputs a rotated content to the printing unit. If not, the processor directly outputs the printing signal to the printing unit.

Abstract: In a digital copier with smart printing function, a sheet size detection module detects a sheet size of a to-be-printed sheet placed in a tray module and generates a sheet size signal, and a scanning module scans a document to obtain a document image and an image signal corresponding to the document image. After a user has pressed a quick copy button to generate a quick copy signal, an image processing module processes the document image into a first image to fit the sheet size by way of scaling or into a second image to fit the sheet size by way of rotating and scaling according to the quick copy signal, the sheet size signal, the image signal and a document size signal, and thus generates a printing signal. A printing module receives the printing signal to print the first image or the second image on the to-be-printed sheet.

The automatic document feeder feeds the document across a scanning region on a sheet passageway for the scanning module to scan. In this invention, a section of a guide plate of the sheet passageway located within the scanning region is formed with a concave portion, wherein the document moving across the scanning region is located between the concave portion and the scanning module, such that the intensity of a first brightness of the concave portion sensed by the scanning module is far smaller than the intensity of a second brightness of the document sensed by the scanning module. Thus, it is possible to facilitate the document edge detection and the document skew correction.
