Abstract

A lens module including a base, a lens, a front cover, at least a shielding plate and a gasket is provided. The lens is disposed within the base. The front cover is disposed over the base and the lens, and the base and the front cover may rotate relatively. The shielding plate is pivoted on the base and has a first guide portion. The gasket is fixed on the front cover, the shielding plate is located between the gasket and the base. The gasket has a through hole corresponding to the lens and a second guide portion coupled to the first guide portion. When the base and the front cover rotate relatively, the first guide portion is guided by the second guide portion, the shielding plate can limitedly swing to move to the through hole to cover the lens or move away from the through hole to expose the lens.
