Beschreibung
Zusammenfassung:	The invention provides a belt tensioning mechanism which is arranged on a scanning module and used for adjusting the belt tension. The belt tensioning mechanism comprises a pressure plate and an elastic body, wherein the pressure plate is fixed on the scanning module; one end of the elastic body is fixed on the scanning module, and the other end of the elastic body is supported against the pressure plate; and the pressure plate is provided with a pressing part which presses a belt. The belt tensioning mechanism is arranged on the scanning module, thereby avoiding manually searching an appropriate position on the belt to install the tensioning mechanism and ensuring that the installation is time-saving and labor-saving; and the whole installation becomes convenient for a scanner driving system with the belt tensioning mechanism.
