    Abstract: A device for calibrating scanned image includes a scanning unit arranged in a paper transmitting path for capturing texts and images on a document and transferring into electrical signals, a set of transmitting device which includes at least a first transmitting roller arranged upstream to the scanning unit, and a second transmitting roller arranged downstream to the scanning unit. There is no other transmitting roller arranged between the first and the second transmitting rollers, the distance between the first and the second transmitting rollers is shorter than the length of the document, and the second transmitting roller is faster than the first transmitting roller. A paper sensor is arranged in the paper transmitting path for detecting the position and the velocity of the document, and a control unit is connected with the paper sensor and the scanning unit to adjust the scan frequency in response to the position and the velocity of the document.

    Abstract: A paper feeding mechanism includes a frame, a drive assembly mounted to the frame, an input tray, a pickup assembly driven by the drive assembly, an elevating assembly and a control assembly. A front end of the input tray is pivoted to the frame, a bottom of the input tray has a pressing portion. The elevating assembly includes a gear assembly driven by the drive assembly, a rotating shaft driven by the gear assembly and located under the input tray, and an elastic element against the bottom of the input tray. The rotating shaft has a cam portion thereon and a notch formed between two ends of the cam portion. The control assembly includes a control system and a paper sensor detecting whether there is any paper on the input tray and control the drive assembly to drive the elevating assembly and the pickup assembly.
