    摘要： A zoom compact camera is provided with a stationary barrel portion and includes a movable barrel that houses a zoom lens. A linear guide groove is formed parallel to the optical axis on the stationary barrel portion. A guide key is provided on the movable barrel. The guide key slidably fits into the linear guide groove to guide the movable barrel. A code plate is fixed to an inner surface in the linear guide groove and a contacting terminal is securely fixed to the guide key to be in sliding contact with the code plate. The focal length of the zoom lens is determined based on a signal indicating the relative position of the contacting terminal with respect to the code plate.
