Abstract: An automatic dust-removing filmscanner comprises a scanner body, a film holder and a dust-removing element. The scanner body has a film-scanning platform and an image-capture module thereinside and has a slot on the surface thereof. The dust-removing element is installed in the film holder. When the film holder is inserted into the slot to locate the film over the film-scanning platform and enable the image-capture module to retrieve the image data recorded on the films, the dust-removing elements on the film holder simultaneously cleans the film-scanning platform. Therefore, the automatic dust-removing filmscanner not only retrieves image data but also automatically cleans the film-scanning platform at the same time without dismantling the scanner body to maintain the scanning quality.
