Abstract:
A foldable structure for folding an optical path, suitable for use in an optical scanner, the optical scanner at least having a main frame, a light transmissible plate, a light source, a reflection mirror set, an image-formation set, and an optical sensor, wherein the light source illuminates a document to get an image light, the reflection mirror set is arranged in an optical path of the image light to project the image light to the optical sensor, the image-formation set is arranged in the optical path between the reflection mirror set and the optical sensor, the document contacts with the light transmissible plate, the folding structure comprising:a foldable packing device coupled to the main frame, and the foldable packing device being able to rotate from a first position, at which the scanner is during a scanning operation, to a second position, at which the foldable packing device is folded, via a pivot axis, wherein the image-formation set and the optical sensor are disposed in the interior of the foldable packing device, wherein when the foldable packing device is at the first position, the optical path of the image light can enter into an interior of the foldable packing device and is projected by the image-formation set onto the optical sensor, and when the foldable packing device is at the second position, the image-formation set and the optical sensor are deviated from the optical path of the image light.
