Abstract

PURPOSE:To project a plurality of laterally and vertically disarranged frames in a correct direction on a monitor screen by mounting a motion picture camera rotatably around an optical axis so that the optical axis of the motion picture camera device is extended vertically to a support surface. CONSTITUTION:A frame to be photographed is arranged right below a circular hole 14 so that the optical axis of a motion picture camera is positioned approximately at the central part of the frame. When the direction of the frame is not correct, a rotary disc 13 is rotated in a 90 deg. arc at a time clockwise or counterclockwise, and is regulated so that the frame is projected on a monitor screen pointed to a correct direction. In this case, since the motion picture camera is rotated around the optical axis thereof, the optical axis is not collapsed, and the frame projected on the monitor screen is not protruded therefrom. A material is then moved to a position on a support surface 5, and when a next frame is projected, by rotating the motion picture camera, the frame can be projected on the monitor screen in a correct direction. There is no need to re-place a sample itself in a manner that the right is left or upside is down.
