ABSTRACT:
A distance measurement device comprises distance measurement device for measuring a distance to an object, a processor for judging a result of the distance measurement of the distance measurement device, a first digital switch connected to the processor for setting a first division point where a measurement range of the distance measurement means is divided into a first long distance side and a first short distance side, a second digital switch for setting a second division point where a range between the first division point and the first short distance side is further divided into a second long distance side and a second short distance side. Based on the set states of the first and second digital switches, the processor determines which area the measurement result of the distance measurement device belongs to, from the plurality of distance areas into which the measurement result of the distance measurement device is divided with the first division point and the second division point.
