PURPOSE: A distance measuring device using a laser scan focus is provided to preciously measure a distance with a simple configuration and method, to reduce costs, to accurately measure a distance in various circumstances. CONSTITUTION: A distance measuring device using a laser scan focus comprises a laser light source, a camera(200), a stepping motor(300), and a central control unit(400). The camera photographs images including an optical point where laser light is reflected to a target and adjust a focus by adjusting a distance between lenses. The stepping motor is rotated by being connected to a timing belt so that the distance between the lenses is controlled. The central control unit calculates a focal distance by using the images photographed at a correct focus and a distance to the target by using the focal distance.
