Abstract
Light rays from an image A are made to enter one or more retroreflective bodies formed by first and second light-reflective surfaces 13 and 14 and third light-reflective surfaces 15, the first and second light-reflective surfaces 13 and 14 each being orthogonal to one another and formed in a right-triangle-wave pattern in cross section, the third light-reflective surfaces 15 being orthogonal to each of corresponding ones of the first and second light-reflective surfaces 13 and 14, a direction of each of one or more reflected lights from the one or more retroreflective bodies is further turned in a different direction on a corresponding one of fourth light-reflective surfaces 16, and an image B is formed at a different position.

An image display apparatus that receives light rays from an image A on one side thereof and forms an image on the other side thereof as an image B, comprising:
- first light-reflective surfaces and second light-reflective surfaces formed orthogonal to one another and continuously;
- third light-reflective surfaces orthogonal to each of corresponding ones of the first and second light-reflective surfaces and arranged vertically;
- and
- fourth light-reflective surfaces each located next to corresponding ones of the first and second light-reflective surfaces and arranged horizontally, wherein
- the image B becomes formed either 1) by light rays from the image A each reflecting off one each of the first to third light-reflective surfaces that form retroreflective bodies and then turning in a different direction on a corresponding one of the fourth light-reflective surfaces or 2) by light rays from the image A each turning in a different direction on a corresponding one of the fourth light-reflective surfaces and then being reflected by a corresponding one each of the first to third light-reflective surfaces that form retroreflective bodies.
An image display method, comprising the steps of:
- making light rays from an image A incident on one or more retroreflective bodies to be formed by first and second light-reflective surfaces and third light-reflective surfaces, the first and second light-reflective surfaces each being orthogonal to one another and formed in a right-triangle-wave pattern in cross section, the third light-reflective surfaces being orthogonal to each of corresponding ones of the first and second light-reflective surfaces;
- further making each of one or more reflected lights from the one or more reflective bodies turn in a different direction on a corresponding one of fourth light-reflective surfaces;
- and
- forming an image B at a different position.
