Abstract
Provided is a prism device applied to a periscope lens module. The prism device includes: a bearing frame; an elastic member including first and second elastic frames; a driving member; a supporting member including a relying portion and rotatably mounted to the bearing frame through the elastic member; and a prism. The driving member drives the supporting member and the prism to rotate relative to the bearing frame. The first and second elastic frames include a first clamping portion and a second clamping portion, respectively, and the first clamping portion and the second clamping portion clamp the relying portion from two opposite sides thereof in such a manner that the supporting member is rotatable about the relying portion. Therefore, when the driving member is driven by the driving member, the prism can be driven to rotate relative to the bearing frame, thereby automatically correcting an angle of the prism.
