Abstract:
1. An image display sheet, which is provided for an object to be observed for position detection and constituted by laminating a lenticular sheet composed of arrangement of a plurality of cylindrical lenses and an image forming layer, and in which an image formed on the image forming layer from a convex shape side of the cylindrical lenses of the lenticular sheet is formed to be observable as virtual image provided with movement, or movement and deformation, wherein the lenticular sheet has a predetermined thickness so that the image forming layer is positioned on a focal surface of the cylindrical lenses, a plurality of images for observing virtual images for displaying single or a plurality of the virtual image in association with the cylindrical lenses are formed repeatedly on the image forming layer so as to correspond to the cylindrical lenses respectively one-on-one, an arrangement pitch length of the cylindrical lenses and a pitch length of the image for observing virtual image formed repeatedly on the image forming layer differs in a range of not more than 10% , the size of the image for observing the virtual image in the arrangement direction of the cylindrical lens and the image for observing the virtual image is the size obtained by reducing the size of the virtual image along the arrangement direction, the size of the image for observing the virtual image in the vertical direction to the arrangement direction is the same size as the virtual image in the vertical direction to the arrangement direction, the virtual image smoothly moving with respect to displacement of an angle at which the object is visually observed is thereby observed, and the virtual image is photographable by a camera for detecting of the position of the object.
