Abstract: A cover adapted to a first electronic device is provided. The first electronic device includes a first electrical connector. The cover comprises: a connecting portion; a covering portion extending from the connecting portion to cover the first electronic device; and a pivot portion. The pivot portion includes a fixing pivot member fixed to the connecting portion; and a magnetic pivot member pivotally connected to the fixing pivot member and including a second electrical connector. The second electrical connector is electrically connected to the first electrical connector when the first electronic device is connected to the magnetic pivot member.

Abstract: A detachable electronic device is provided. The detachable electronic device is adapted to a cover with a plurality of folding sections. The detachable electronic device comprises: a body including a first surface and a second surface and a peripheral unit detachably connected to the body and including a pivot portion. The first connector is disposed at the first surface. The pivot portion includes a fixing pivot member and a magnetic pivot member pivotally connected to the fixing pivot member and including a second connector. When the first connector is magnetically attached to the second connector and the body is supported by folding the folding sections of the cover, the pivot portion is raised up by a distance from a support surface against which the peripheral unit abuts.
