ABSTRACT:
A distance measurement device comprises at least one switch for generating a start signal, a distance measurement device for measuring the distance to an object in response to the start signal, a memory device for storing distance data measured by the distance measurement device, the stored data defining a plurality of measurement zones within the full range of distance measurement of the distance measurement device, and a judgement circuit for judging which measurement zone the result of the distance measurement performed by the distance measurement means belongs to from the plurality of measurement zones defined by the distance data stored in the memory device. In accordance with this configuration, division points can be set if an object is placed at an actual division point desired and a switch is pressed. Accordingly, when an operator sets the division point, it is unnecessary to depend on memory, perception, or calculation, and the setting of the division points becomes easier. A timer may be used to facilitate the setting of the long distance side division point even in the case of only one operator. In addition, setting circuitry, such as a digital switch, becomes unnecessary, so the construction of the device may be substantially simplified. Moreover, since the division points can be easily set to any distance within the distance measurable range, they can be set with a high degree of accuracy.
