POSITIONING DEVICE
Document Type and Number:
Japanese Patent JPH03180912
Kind Code:
A
Abstract:
PURPOSE:To shorten the moving time of a moving object by detecting the moving direction and position of the moving object and deciding whether the moving object is moved to a position control range or not by a deciding means. CONSTITUTION:The positioning device is provided with a positional direction detecting means 6 for previously determining the 1st speed and the 2nd speed larger than the 1st speed as regulated speeds and detecting the position and moving direction of the moving object, a deciding means 7 for deciding whether the moving body is approached or separated to/from the position control large based upon the detecting position and the detecting direction and a speed setting means 7 for setting up the 2nd speed as the regulated speed at the time of deciding that the moving object is approached to the position control range and setting up the 1st speed as the regulated speed at the time of deciding the object is separated from the range. Thereby, when the moving object is moved to the position control range, the upper limit value of the moving speed is set up to a high speed. Thus, the moving time of the moving object can be shortened.
