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.

Claim (Index 5):
A sheet feeding method applied in an image scanning device for scanning sheets, the image scanning device including a roller element, a contact image sensor, a plurality of springs, and a motor driving the roller element to rotate in different speeds, the contact image sensor being mounted to the plurality of the springs, a top surface of the contact image sensor being capable of abutting against a lower portion of an outer surface of the roller element, the sheet feeding method comprising steps of:\n driving each of the sheets which are to be scanned to be fed forward to a preset position by virtue of the roller element rotating, each of the sheets which are to be scanned pushing against the contact image sensor to move downward, the plurality of the springs being compressed, an interval being formed between the lower portion of the outer surface of the roller element and the top surface of the contact image sensor; reading image read values of the outer surface of the roller element, and the contact image sensor recording the image read values of the outer surface of the roller element at different intervals, namely different distances of which each is between the outer surface of the roller element and the top surface of the contact image sensor, confirming the distances of which each is between the outer surface of the roller element and the top surface of the contact image sensor according to the image read values of the outer surface of the roller element, namely thicknesses of the fed sheets which are to be scanned; according to the different intervals of which each is between the outer surface of the roller element and the top surface of the contact image sensor, different feeding speeds being separately set corresponding to rotation speeds of the motor; and according to the thicknesses of the fed sheets which are to be scanned, automatically choosing corresponding feeding speeds to feed the sheets which are to be scanned so as to proceed scanning.
