Abstract: A distance measuring device includes a measuring unit, a controlling unit, and an accessory part. The measuring unit includes an applying unit that applies a transmission wave and a detector that detects a reflected wave resulting from the transmission wave. The controlling unit is configured to perform a measurement, by using the measuring unit, a distance to an object to which the transmission wave is applied. The accessory part is attached to the measuring unit and configured to operate when energized. The controlling unit is configured to control energization of the accessory part in accordance with a state of the measurement of the distance performed by using the measuring unit.
