A cover assembly of an image capturing device is provided. The image capturing device includes a housing having a platen for supporting the document. The cover assembly includes a buffer, a background sheet and a stretching-compressing mechanism. The cover is pivotally connected to the housing and has an inner surface facing the platen. The buffer is disposed on the inner surface, and the background sheet is disposed on the buffer. The stretching-compressing mechanism connects the buffer and the inner surface for being compressed or stretched to apply a force on the buffer and the background sheet to make the buffer and the background sheet press the document on the platen or to make an end of each of the background sheet and the buffer part raised from the document and the other parts of the background sheet and the buffer press the document on the platen.
