Scanning device having a rotatable and length-adjustable hinge for coupling a cover with a scanning body

摘要

A scanning device comprises a scanning body, a hinge and a cover. The scanning body has a first slot horizontally extended and formed at one side of the scanning body. The hinge has an upper portion and a lower portion engaged to each other and relatively movable for changing a length of the hinge. The lower portion of the hinge is disposed in the first slot and rotatably coupled to the scanning body. The cover is rotatably coupled to the upper portion of the hinge. When the cover is in a closed position, the hinge is received in the first slot. When an original medium to be scanned with a thickness is placed on the scanning body and positioned by the cover, the hinge is correspondingly rotated to a first position and extended to a first length.
