PROBLEM TO BE SOLVED: To increase the speed of two-dimensional scans made by an infrared temperature measuring apparatus and to reduce the occupancy area. SOLUTION: An infrared element is retained by a shaft, and an X-axis gear 7 is rotatably mounted about the shaft serving as an axis and is periodically rotated back and forth by an X-axis motor 4. A reflector 8 having a Y-axis as its axis of rotation which is perpendicular to the X-axis, a Y-axis gear 11, and a Y-axis motor 9 which causes periodic rotations back and forth are mounted on the X-axis gear 7. High speeds are achieved through weight reduction and the elimination of an external shielding wire, and reduction in the occupancy area is also achieved.
