PROBLEM TO BE SOLVED: To reduce the burden of subject and improve imaging efficiency by sequentially moving vertically and horizontally based on the set feed volume that is calculated, based on the position data of light localizer, the distance from the pointing position to the magnetic filed center, vertical and horizontal directions, as a set feed volume. SOLUTION: A marker line 82c, which is longitudinal direction from a light localizer 80A to a bed 71, and a marker line 82b, which crosses at right angles to longitudinal direction, are projected with forming a intersection 81. Marker lines 82c are projected from light localizer 79A, 79B to horizontal direction with same height. Adjusting light localizer 79A, 79B, 80A to the photographing part, the values of resistance, which are detected with the potentiometers of light localizer 79A, 79B and 80A, are converted to analog voltage value or digital data with interface circuit. Then recognizing the data, calculating the distance to the magnetic field center, and deciding the set feed volume, the driving circuit is driven to move a top board.
