Abstract

PURPOSE: To permit accurate persuit of the position of an object by disposing three object detectors at a detecting point and combining the signals from these detectors.
CONSTITUTION: At an instant when the leading end of an object 2 proceeding in the forward direction reaches a position right beneath an object detector unit 3, S1-"on" is recorded as history. Then, at an instant when the leading end of the object 2 reaches a position right beneath S2 a forward-"on" signal is detected under the assumption that the object 2 is proceeding in the forward direction so long as the memorized content of the hystory is S1-"on". If the memorized hystory content is other than S1-"on" at this time, a signal S2-"on" is ignored as abnormal interruption. In this way malfunction can be prevented.
