特徴とする自動合焦装置。[Claims for Utility Model Registration] A cam and a driven joint that are linked to the back and forth movement of a focusing lens in a photographic lens change the distance between a light emitting element and a light receiving element that are arranged in a direction that intersects with the direction of the back and forth movement. In an automatic focusing device of a camera that detects the in-focus state by the change in light emitted from the light emitting element, reflected by the subject, and received by the light receiving element, which occurs due to the distance change, the driven joint is levered. 1. An automatic focusing device comprising: a lever; the lever is disposed such that the amount of change in distance between the light receiving element and the light emitting element is reduced relative to the amount of displacement of the cam.
