A distance measuring device includes a light emitter; a light receiver; a protection cover that is located on an optical path between the light emitter and the light receiver; a mode switch that switches between a first mode and a second mode; a distance calculator that calculates a distance from a target object based on a difference between a time when light is emitted from the light emitter and a time when reflected light is received by the light receiver in the first mode; and an LD light emission intensity adjuster that adjusts a light emission intensity of the light emitter. The adjustment is performed such that a light emission intensity of the light emitter in the second mode is lower than a light emission intensity of the light emitter in the first mode.
