    Abstract: The present invention is related to a scanning device for scanning documents, comprises a flat-bed scanning glass; a contact image sensor arranged above the flat-bed scanning glass separately to form a scanning path therebetween, a bottom surface of the contact image sensor being arranged with a protecting glass, a middle area of the protecting glass being configured as a scanning area, and a chamfer being arranged at the bottom surface of the protecting glass at a downstream position relative to the scanning area. Hence the dust of documents in this invention would be stacked in the chamfer during the scanning process temporarily and then be wiped away by the document itself, so as to assure the dust would not be stacked in the scanning area. The scanning device in this invention is capable to maintain the scanning quality without clearing the dust even after scanned a massive quantity of documents.

    Abstract: A paper pickup mechanism includes a mechanical frame, a pickup roller module, a feeding roller module, a driving device, a separation roller module and an energy storage element. The mechanical frame has a platform. The pickup roller module is pivoted to and connected to the mechanical frame. The feeding roller module is pivoted to and connected to the mechanical frame. The driving device is mounted to the mechanical frame. The separation roller module is pivoted to and connected to the mechanical frame. The energy storage element is mounted between the mechanical frame and the separation roller module. When the separation roller module rotates together with the feeding roller module in a forward direction, the energy storage element accumulates energies. When more than one piece of paper is fed into the paper pickup mechanism, the energy storage element releases the energies.

    Abstract: An image scanning device includes an upper shell, a feeding shaft pivotally connected to the upper shell, a feeding roller mounted around the feeding shaft, a sensing roller, a motor, a lower shell pivotally covered to the upper shell, a plurality of springs and a contact image sensor. The sensing roller is mounted around the feeding shaft. The motor is connected with the feeding shaft. The motor drives the feeding shaft to rotate in different speeds. The plurality of the springs are mounted to the lower shell. The contact image sensor is mounted to the plurality of the springs. A top surface of the contact image sensor is capable of abutting against lower portions of outer surfaces of the feeding roller and the sensing roller by virtue of the plurality of the springs elastically abutting against a bottom surface of the contact image sensor.

    Abstract: A paper warping detection device includes an input tray, a processor, a first emitting element, a first receiving element and a first analog-to-digital converter. A first critical value is stored in the processor. The first emitting element is electrically connected with the processor. The first receiving element is disposed to the other side of the input tray. The first receiving element and the first emitting element face each other. When the first emitting element is switched on, the first emitting element emits first ultrasonic wave signals towards the first receiving element. The first analog-to-digital converter is electrically connected with the first receiving element and the processor for converting the first ultrasonic wave signals into first digital signals and outputting the first digital signals to the processor. The processor reads the first digital signals and compares the first digital signals with the first critical value.

    Abstract: An image scanning method applied in an image scanning device capable of scanning a card. Record background values at the time of a card being without being in a scanning channel, and the background values recorded at the time of the card being without being in the scanning channel are regarded as preset values. Before the card is scanned, check whether the background values in the scanning channel conform to the preset values. Drive the card to move a distance Y. Check whether the background values in the scanning channel conform to the preset values. Preset a preset movement distance, check whether a movement distance of the card or a distance of accumulated movements of the card exceeds the preset movement distance. Display that the card is stuck. Stop checking and proceeding an image calibration. Start scanning the card. Complete scanning the card and withdraw the card.

    Abstract: A scanning device includes a base, an upper cover pivotally covered to the base, a motor mounted to the base, two roller assemblies, a sensor mounted in the first channel, and a card supporting mechanism. A first channel, a scanning channel and a second channel are formed between the upper cover and the base. The scanning channel has a scanning read line. The first channel, the scanning channel and the second channel are communicated with one another. The two roller assemblies are connected with and driven by the motor. The card supporting mechanism is mounted to the base. The card supporting mechanism includes a blocking board movably disposed behind the second channel along the longitudinal direction, and a front surface of the blocking board is parallel to the scanning read line and orthogonal to the second channel.
