Abstract
A sheet-feeding type scanning apparatus and an automatic sheet feeding method are provided. The sheet-feeding type scanning apparatus includes a scanning module, a first sheet input tray, a first sheet pick-up roller assembly, a sheet ejecting tray, a sheet transfer channel, a plurality of transfer roller assemblies, a sheet ejecting roller assembly, a sheet-feeding sensor and a clutch module. Once a first sheet article of multiple sheet articles placed on the first sheet input tray are fed into the internal portion of the sheet-feeding type scanning apparatus to trigger the sheet-feeding sensor, the clutch module is disabled. At this moment, a second sheet article placed on the first sheet input tray fails to be fed by the first sheet pick-up roller assembly. Therefore, the double feeding problem is solved.
