面に対して角度αだけ傾け、この角度αが、 ０＜α≦ｔａｎ−１［ｆ／Ｌ］ の条件を満足することを特徴とする測距装置。[Scope of Claim for Utility Model Registration] A light-receiving section consisting of a light-receiving element and a light-receiving lens with a focal length f, and a light-emitting section provided at a distance from the light-receiving section by a base line length L, and from the light-emitting section. In an active distance measuring device, the distance to the subject is determined based on the imaging position where the emitted light is reflected from the subject surface and forms an image on the light receiving element via the light receiving lens. The end of the light-receiving element on the side where the light reflected from the surface is imaged is close to the light-receiving lens, and the end of the light-receiving element on the side where the image is formed of the light reflected from the object surface at a close distance is far from the light-receiving lens. The light-receiving surface of the light-receiving element is tilted by an angle α with respect to a plane perpendicular to the optical axis of the light-receiving lens, and this angle α satisfies the following condition: 0<α≦tan −1 [f/L] A distance measuring device featuring:
