Abstract

A device for detecting posture change of a operation part in a camera and a method for restoring posture are disclosed. The device may include a photo interrupter and a photoelectric baffle structure including a plurality of baffle pieces fixed on a base. The baffle pieces may include a first baffle piece and remaining second baffle pieces of a length specification different from that of the first baffle piece, and there is a gap between two adjacent baffle pieces. An output signal from the photo interrupter changes according to the aligning relationship between the photo interrupter and the baffle pieces. One of the photoelectric baffle structure and the photo interrupter may follow the motion of an operation part of the camera while the other one remains unmoved, so that a posture change of the operation part may be detected based on the output signal from the photo interrupter.
