Beschreibung
Zusammenfassung:	A ranging apparatus includes: a main body including a light emitting device and a light detector; a signal processing circuit; a vibration detector; a control circuit. The light emitting device is capable of emitting a light beam in a plurality of directions at different elevation angles. The light detector detects reflected light of the light beam. The signal processing circuit generates distance data based on a signal outputted from the light detector. The vibration detector detects a change in attitude of the main body attributed to vibration in distinction from a change in attitude of the main body attributed to an inclination of a ground surface at a location where the main body is installed, and outputs a vibration signal indicating an amount of change in the attitude attributed to the vibration. The control circuit corrects a direction of emission of the light beam to be emitted from the light emitting device based on the vibration signal.
