距装置。In a distance measuring device that measures the distance to the target object according to the light receiving position of a light receiving element that receives a spot image projected from a light projecting element and reflected by the target object, the light path of the spot image or A part of either one of the light receiving optical paths is constituted by a first variable magnification optical system capable of changing image magnification, and the magnification of the variable magnification optical system is adjusted in conjunction with the change in magnification of the first variable magnification optical system. A distance measuring device characterized in that a second variable magnification optical system is provided in the optical path of the spot image for changing the image magnification in a direction to eliminate fluctuations in the size of the spot image caused by the change.
