A make useful assistance at the time when the transportation machine are relatively positioned such that the optimal position and orientation to the loading operation by the loading machine. The A dump truck 2 with respect to the drilling machine 1 in order to proceed rapidly and smoothly at a position loading work as a target is performed, arranged in a loading target position dump truck 2 with respect to the drilling machine 1 to, by detecting the geographical position GPS receiver 32 of the dump truck 2 from the GPS satellites 30, and transmitted to the excavating machine 1 and its position and orientation as the target position image P1, the subsequent entry of the dump truck 2 sometimes, the dump truck 2 as the dump truck 2 of the display 36 to display the entry route R of the target position image P1 to it, a current position image P2 proceeds to the target position image P1 along the approach route R by operating, arranged on loading target position set the dump truck 2. .Field
