A multifunction book cover combining with office and/or study unit provides with a flat with a cavum (10). A transfixion window (11) setting in the flat. At least two suit metal connecting pins (20) are posited at an upper fringe and a lower fringe of the window. The metal connecting pins may be an electricity-link unit and can be telescopic. A frame (30) is replaceably fixed in the window (11) by the metal connecting pins. One or tow of a picture, a drawing or personal digital palmtop (40) can be set in the frame. Because the book cover combines with the personal digital palmtop, a speakerphone, a light etc, and can be used as a picture frame, so that it provides more expedience for working and studying. |
