Scanning apparatus and guiding mechanism thereof

Abstract

A scanning apparatus comprises a light-pervious plate, an optical device, and a guiding mechanism. The light-pervious plate provides a plane for placing an object to be scanned. The optical device is disposed under the light-pervious plate for capturing the image of the object and transforms the image into the corresponding signal. The guiding mechanism further comprises a guide bar, a loading frame, and an elastic element. The guide bar is disposed in the scanning apparatus and provides a scanning path. The loading frame, including a guide slot, is assembled with the optical device. Since the guide slot coordinates the guide bar, the optical device is mounted to move along the scanning path. The elastic element, disposed within the guide slot, exerts an elastic force toward the guide bar to reduce the gap between the guide slot and the guide bar so that the optical device can get better image of the document.
