ROAD SURFACE REFLECTING TYPE DELINEATOR DEVICE AND DELINEATOR SYSTEM
To provide a road surface reflecting type delineator device which does not adversely affect the human body even when a pedestrian or the like approaches the light source of the delineator device, and which allows a vehicle driver to sufficiently see the line markings on the road surface even in bad weather.SOLUTION: A road surface reflecting type delineator device 1 includes a light source 2 that irradiates a line laser light from above to a road surface of a road to perform a line marking on the road surface. The light source has a housing 3 that houses a laser oscillator 21. In the housing, a window 31a is formed on the front wall so as to face the laser emitting portion of the laser oscillator, and a safety device 5 extending in the laser light emitting direction is provided in which the window is disposed inside thereof. The laser oscillator has a higher laser light output than safety class 2 defined by JISC6802. The safety device is to be located at the back of the window so that no human eyes can approach the window from the front, and the length of the laser light output from the tip of the safety device is to meet safety class 2.SELECTED DRAWING: Figure 2
【課題】歩行者等が視線誘導装置の光源に最接近した時でも人体に悪影響を及ぼすことなく、悪天候の時でも車両運転者には路面上のライン標示が十分に見えるようにする路面反射式視線誘導装置を提供する。【解決手段】路面反射式視線誘導装置１はラインレーザー光を上方から道路の路面に向けて照射して路面上にライン標示を行う光源２を備える。光源はレーザー発振器２１を収容するハウジング３を備える。ハウジングには、その前壁板にレーザー発振器のレーザー光出射部を臨ませる窓部３１ａが形成され、この窓部を内側に配置してレーザー光の出射方向に延びる安全具５が設けられている。レーザー発振器はレーザー光出力がＪＩＳＣ６８０２で定める安全クラス２よりも高出力であり、安全具は窓部に正面から人の目が近づけないように窓部を奥まった位置に配置させ、安全具先端部からのレーザー光出力が安全クラス２を満たす長さとする。【選択図】図２
