Abstract
PURPOSE:To efficiently execute the exact reading of a recorded image when it is in a concentric circle shape, for example, by executing the reading of image information in the concentric circle shape or in a spiral shape on a recording board. CONSTITUTION:Since the reading of the image information from an image recording disk is executed by a scanning in the concentric circle shape or the spiral shape on the recording disk 1, the image information can be efficiently sampled along the contour of the image when the recorded image is the X-ray diffracted image of a crystal construction material, etc., and it is wholly in the almost concentric circle shape or a shape to resemble it. Then, the exact reading can be efficiently executed. Since the declination of a reading position on respective scanning circles are mutually dislocated and set between the mutual scanning circles to be neighboring each other so that the reading position of the mutual image information can not be overlapped in a normal direction mutually between the neighboring scanning circles, the image can be exactly drawn to an image display means 3 of an X-Y scanning type without increasing the information quantity of the reading so much.
