Abstract

PURPOSE: To enable a high-precise positioning of a device by means of an inexpensive position detector, by a method wherein a comparatively coarse-staged target speed curve is formed at a part being away from a stop target, and a target speed curve, in which only a part in proximity of the stop target is caused to change continuously, is formed.
CONSTITUTION: An object 21 to be detected, attached to a pallet, has a smooth curve at its upper surface and equal-spaced notches in its lower surface, and as against the object 21, gap detectors A3 and B3 are securedly located when the upper surface of the object to be detected approaches, and the output is caused to change according to an approrching state. Meanwhile, approaching switches A2 and B2 are also securedly mounted symmetrically centering around the stop target O1, and detect the notches in the lower surface of the object to be detected. The approach switches A2 and B2 generates On and OFF signals (a) and (c), which correspond to the teeth shape of the object 21 to be detected, to changes in the position of the pallet center O1.
