BACKLIGHT PREVENTION MECHANISM OF OUTDOOR DISPLAY DEVICE, OUTDOOR DISPLAY DEVICE AND BACKLIGHT PREVENTION METHOD
PROBLEM TO BE SOLVED: To secure appropriate visibility in a backlight condition without particularly changing a structure of an outdoor display mounting portion in various outdoor display devices such as road signs and outdoor advertisements.SOLUTION: A concave reflection mirror 3 for reflecting backlight (3a and 3c) incident on a road sign board 1 in a display surface 1a showing display information 1b is provided to extend along a lateral direction of the display surface 1a, in a front upper part of the display surface 1a, that is, in a position not to prevent a user of the road sign board 1 from visibly recognizing the display information 1b.
【課題】 道路標識および屋外広告などの各種屋外表示装置において、屋外表示装部自体の構造を特に変えることなしに、逆光状態における十分な視認性を確保することを目的とする。【解決手段】 道路標識板１への入射逆光（３ａ，３ｃ）を表示情報１ｂが記された表示面１ａに反射させるための凸面状反射鏡３を、表示面１ａの横方向に沿って延びる形で表示面１ａの前方上側部分、すなわち、道路標識板１の利用者が表示情報１ｂを視認する際の妨げとならない位置に設けた。【選択図】図２
