PROBLEM TO BE SOLVED: To suppress misrecognition of an optical beacon on-vehicle machine.SOLUTION: The present invention relates to an optical beacon on-vehicle machine 10 having an optical communication element 13 accommodated in a case 12, which has an opposite wall facing the optical communication element 13, the opposite wall having a light transmission part 27, transmitting light to be used for optical communication with the optical communication element 13, in a region facing at least the optical communication element 13 and also having a light blocking part 29, lower in light transmissivity of the light to be used for the optical communication with the optical communication element 13 than the light transmission part 27, in a region, different from the light transmission part 27, of the opposite wall.SELECTED DRAWING: Figure 4

    【課題】光ビーコン車載機の誤認識を抑制する。【解決手段】ケース12内に光通信素子13が収容された光ビーコン車載機10であって、ケース12は、光通信素子13と対向する対向壁を有し、対向壁は、少なくとも光通信素子13と対向する領域に、光通信素子13との光通信に使用される光を透過する透光部27を有しており、対向壁のうち透光部27と異なる領域には、光通信素子13との光通信に使用される光の透光性が透光部27よりも低い遮光部29を有する。【選択図】図4
