Abstract

PURPOSE:To prevent that an alarm is emitted by error even when an object of an approach state moves to a non-dangerous region at the next transmission point of time, by providing a preparatory detection area to a region remote from a usual detection area. CONSTITUTION:When the object 10 approaching an ultrasonic sensor 1 moves to a preparatory detection area C being a region remote from a detection area B at the next detection point of time of the object 10, the object 10 present in the area C is also detected. The distance up to the object 10 is calculated to be used as distance data judging the present position of the object 10 and it is judged whether the object 10 is present in a dead angle region A or in the area C. Therefore, when the object 10 approaching the sensor 1 moves to the area C being the region remote from the area B at the next detection point of time of the object, an alarm is not emitted by error.
