Publication number: 20150364844Abstract: An electronic card protecting mechanism is adapted to an electronic device including a casing. The electronic card protecting mechanism includes a base, a substrate, an elastic component and a positioning component. The base is slidably disposed in the casing and has a covering plate having a slot. The substrate is disposed on the base and aligned to the slot.
