ABSTRACT:
A device for determining the measurement zone of an object which permits the adjustable setting of a plurality of measurement zones bounded by user-defined division points comprises a distance measurement apparatus for measuring a distance to an object, a specific division point setting circuit, such as a digital switch, for adjustably setting a specific distance point within the effective measurement range of the distance measurement apparatus, a circuit for adjustably setting one or more predetermined division points on at least one of the near side and the far side of the specific distance point, such that the specific distance point and the at least one predetermined division point define a plurality of measurement zones within the effective measurement range of the distance measurement apparatus, and a judgment circuit for judging which of the plurality of measurement zones a distance measurement result of the distance measurement apparatus belongs to. A measurement zone having a fixed width can be set by the setting circuit and the distance setting of division points can be performed by merely placing an object at an easily measurable point and pressing a switch. The division points can be set with very few manual operations. Also, a timer may be included to permit setting of the division point on the far side even when only one operator is present.
