Abstract: An electronic device includes a tablet module and a docking base. The tablet module includes a slot, a sliding element and a plurality of first attracting elements. The sliding element is slidably disposed in the slot. The first attracting elements are adjacently disposed on the sliding element and have a first attracting side. The polarities of each two adjacent first attracting elements at the first attracting side are different. The docking base includes a bearing sheet and a plurality of second attracting elements. The bearing sheet is inserted to the slot and abuts against the sliding element. The second attracting elements are adjacently disposed on the hearing sheet and have a second attracting side. The polarities of each two adjacent second attracting elements at the second attracting side are different.

Abstract: A paper-feeding device with functions of single-face/double-face scanning and printing. The paper-feeding device has a simplified structure and reduced height, whereby a paper can be more smoothly delivered through a scanning module and/or a printing module in a paper delivery path of the paper-feeding device. The paper delivery path includes: a first path having a front section and a rear section; a second path connected to the rear section of the first path, an angle contained between the rear section of the first path and a horizontal reference axis and an angle contained between the second path and the horizontal reference axis ranging from 0° to 30°; a return path positioned between the first and second paths; and a paper discharge path. The paper can be selectively moved between the first and second paths and the return path to complete the single-face/double-face scanning and printing operation.
