Abstract:
1. An electromagnetic handwriting pen for concurrently providing ink writing and electromagnetic writing functions, comprising: a casing unit including a pen-shaped casing structure; an ink writing unit including an ink pen core disposed inside the pen-shaped casing structure and a retractile mechanism disposed inside the pen-shaped casing structure, wherein the ink pen core has a pen nib for providing ink, and the pen nib of the ink pen core is projected from or returned into the pen-shaped casing structure through the retractile mechanism; and an electromagnetic writing unit disposed inside the pen-shaped casing structure, wherein the electromagnetic writing unit includes a circuit substrate far away from the pen nib, an electricity conducting element adjacent to the circuit substrate, an elastic element insulatively disposed between the circuit substrate and the electricity conducting element, and a magnetic structure adjacent to the pen nib and electrically connected to the circuit substrate, and the circuit substrate has at least two electrode portions adjacent to the electricity conducting element and facing the electricity conducting element; wherein, when the electricity conducting element is moved to concurrently contact the at least two electrode portions by pushing the ink pen core, the at least two electrode portions are electrically connected with each other through the electricity conducting element.
