PROBLEM TO BE SOLVED: To solve the problems that an operator performs positioning by looking at the body surface of a subject and imagining the positions of internal organs and bones and does not determine a radiographing range with necessary sufficient accuracy while the operator has to set a start point position and an end point position by moving a top plate where the subject is placed beforehand or the like when performing long length radiographing by slot scan radiographing, and work efficiency needs to be improved since the radiographing range is specified by such a method near the subject inside an examination room and radiographing thereafter is performed by moving to an operation room. SOLUTION: By displaying a long length image radiographed beforehand for each subject and preserved together with top plate position information of the start point and the end point on an image display part 12 and specifying the positions of the start point and end point of long length radiographing to be performed from then with cursors 12A and 12B on the image, a device automatically calculates the moving range of the top plate.
