<P>PROBLEM TO BE SOLVED: To provide a positioning device with a simple structure capable of setting the operation starting time of an operation unit and a control method thereof. <P>SOLUTION: When a mover 22 moving along a predetermined guide path stops, the operation unit 24 is subjected to residual vibration based on the inertial force acting on the operation unit 24 supported on the mover 22. At that time, the waveform of a sensor signal output from a sensor 32 is observed. Thus, the residual vibration is detected according to the sensor signal output from the sensor 32. The position of the operation unit 24 can accurately be specified based on the waveform of the sensor signal. The position of the operation unit 24 is specified as suitable for operation. Thus, the operation starting time of the operation unit 24 can be set. Even during the residual vibration, the operation unit 24 can start operation in a short time after the stoppage of the mover 22. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
