A plate lifting device capable of being applied to a multi-plate equipped apparatus includes a motor, a retractable shaft, a restriction member, and a lifting mechanism disposed on the base. The motor is disposed on a base of the multi-plate equipped apparatus. An end of the retractable shaft is pivotally disposed on the base and is connected to the motor, whereby to be driven by the motor to extend or retract, and another end thereof has a movable member. The restriction member connected to one of the plates of the multi-plate equipped apparatus has a slot capable of being passed through by the movable member. When the motor drives the retractable shaft to extend from an initial state, the movable member is lifted by the lifting mechanism, so that the restriction member and the plate connected to the restriction member, which are moved together with the movable member, are lifted.
