Abstract: An image scanning method is applied in an image scanning device which includes an input tray and a paper feeding sensor. The method detects whether there are papers on the input tray in step one. If there are papers, step two is executed. Otherwise, the method ends and an error is reported. In step two, papers are separated and fed. Whether the papers contact the paper feeding sensor is detected in step three. The method executes step four if the papers contact the paper feeding sensor, and ends the method with an error message otherwise. In step four, the method scans and detects whether an image of a fed edge of each of the papers is abnormal. If the image is abnormal, the method ends and an error is reported. Otherwise, scanning continues.

Abstract: An automatic gluing machine includes an automatic gluing mechanism. The automatic gluing mechanism includes a sleeve, a pushing component mounted to the sleeve, an assembling head, and a driving module including a gear module. The sleeve is equipped with a first sleeve gear. The pushing component includes a rotating body and a first rotary gear. The assembling head is assembled inside the sleeve.

The separated paper by the separating mechanism co-working with the picking mechanism passes rearward through the detecting mechanism. The detecting mechanism detects a relative distance between two adjacent papers which successively pass through the detecting mechanism so as to control the picking mechanism to adjust transmission speed of the papers for achieving a fixed distance between two adjacent papers.
