When a thin document is copied and scanned, as shown in fig. 2 and 3, the upper cover plate 2 can be directly opened to place the scanned document to be copied. In this process, since the thickness of the document is thin, the upper cover 2 can be completely closed without sliding the upper cover 2 upward. With continued reference to fig. 4, when copying and scanning thick documents, such as books, the upper cover 2 needs to be pulled upward, and the connecting member 3 slides in the receiving groove 12 during the upward pulling of the upper cover 2. When the upper cover plate 2 slides to a designated position, the upper cover plate 2 is covered.
