Electronic device

An electronic device, comprising:

• a tablet module including a slot, wherein the tablet module includes:
• a sliding element slidably disposed in the slot;
• and
• a plurality of first attracting elements adjacently disposed on the sliding element and including a first attracting side, wherein polarities of each two adjacent first attracting elements at the first attracting side are different;
• and
• a docking base including:
• a bearing sheet inserted to the slot and abutting against the sliding element;
• and
• a plurality of second attracting elements adjacently disposed on the bearing sheet and including a second attracting side, wherein polarities of each two adjacent second attracting elements at the second attracting side are different,
• wherein the polarity of each of the first attracting elements at the first attracting side is different from the polarity of the corresponding second attracting element at the second attracting side, and the first attracting side is attracted with the second attracting side,
• the polarity of each of the first attracting elements at the first attracting side is the same and repulsive with the polarity of the second attracting elements which are beside the corresponding second attracting element at the second attracting side, the polarity of each of the second attracting elements at the second attracting side is the same and repulsive with the polarity of the first attracting elements which are beside the corresponding first attracting element at the first attracting side, and each of the first attracting elements is guided to align to the corresponding second attracting element.
