<P>PROBLEM TO BE SOLVED: To appropriately monitor whether or not a predetermined operation to be executed to an operation position during conveyance of an operation object is completed by precisely specifying a position of an operated position where the operation is completed. <P>SOLUTION: A torque wrench 8 is provided with: a radio wave transmitter 27 and an ultrasonic wave transmitter 28, and a palette 4 of a palette type conveyance machine 2 is provided with a receiver 29. The receiver 29 receives the respective signals to be transmitted from the radio wave transmitter 27 and the ultrasonic wave transmitter 28 to calculate distance Ln between the transmitter and the receiver. A CPU 33 of a processor 30 calculates position coordinates of a tightened part in an operation object coordinate system by using the distance Ln between the transmitter and the receiver, determines whether or not tightening operations are completed at all the tightening parts, and displays the position coordinates and discrimination results of the tightened part on a display 41. <P>COPYRIGHT: (C)2013,JPO&INPIT |
