PROBLEM TO BE SOLVED: To provide a confirmation device capable of confirming whether or not a latent image smoothly moves and can be visually confirmed without occurrence of a non-observation area in considering energy saving and space saving.SOLUTION: A confirmation device of a bright medium which is visualized by having a video effect by a base image due to a change of an observation angle includes at least: an irradiated part for fixing the bright medium in a state of mounting the bright medium while holding smoothness; an irradiation part disposed on the upper part of the irradiated part and moving to a first direction in which a two-dimensional direction of a light source is at least the same as the first direction in a state of holding the bright medium and irradiation light from the light source at a fixed elevation angle; a diffusion part for diffusing the irradiation light from the light source to a second direction orthogonal to the first direction; and a control part for controlling a position and the turn-on/turn-off of the light source. Diffusion means have a cylindrical lens in a line shape arranged in a numerous-line shape in the second direction.SELECTED DRAWING: Figure 2 【課題】 省エネルギー及び省スペースを考慮した上で、非観察領域が発生せずに、潜像がスムーズに動いて視認されるか否かを確認可能な確認装置を提供する。【解決手段】 観察角度の変化により基画像が動画効果を有して視認される光輝性媒体の確認装置であり、光輝性媒体を載置した状態で平滑性を保ちながら固定する被照射部と、被照射部の上部に配置され、光輝性媒体と光源からの照射光を一定の仰角を保持した状態で、光源が第１の方向と少なくとも二次元方向が同じ方向である第１´の方向へ移動する照射部と、被照射部と照射部の間に、光源からの照射光を、第１の方向と直交する第２の方向に拡散する拡散部と、光源の位置及び点灯／消灯を制御する制御部を少なくとも有し、拡散手段は、ライン状のシリンドリカルレンズが第２の方向に万線状に配置されて成ることを特徴とする。【選択図】 図２
