自動焦点装置。[Claims for Utility Model Registration] A lens that allows light from a subject to pass through, a linear image sensor that detects the light that has passed through the lens and outputs a detection signal, and a linear image sensor that detects the light that has passed through the lens and outputs a detection signal, based on the detection signal from the image sensor. In-focus point detection means for outputting a lens movement signal or a lens stop signal;
In an automatic focusing device having a lens moving means that receives a lens movement signal or a lens stop signal from the focused point detection means and moves or stops the lens, if the focused point cannot be detected, the lens is moved. Rotating the linear image sensor in a plane perpendicular to the optical axis of the light from the object that has passed,
An automatic focusing device characterized by comprising a sensor rotation driving means that enables output of the detection signal at a different position.
