DISPLAY DEVICE FOR RAILWAY

PROBLEM TO BE SOLVED: To prevent a degradation of visibility as to a large-sized railway display device such as a relay signaling device or a line indicator in which a display portion is covered with a cover having a transparent plate on which a transparent conductive film is formed, which is caused by snowfall, without increasing power supply facilities.SOLUTION: While a display portion 2a of a railway display device 1 is constituted by a plurality of lamps 22a to 22g arranged so as to spread two-dimensionally with a predetermined interval therebetween, transparent conductive films 35a to 35c are disposed in front portions of first lamp groups 22b and 22d arranged linearly among the plurality of lamps 22a to 22g in a transparent plate 34, and front portions of second lamp groups 22f, 22a, 22g arranged in parallel with the first lamp groups 22b and 22d adjacent to the first lamp groups 22b and 22d in such a manner that the lamps 22b, 22d of each lamp group are arranged in a belt shape extending in the arranging direction thereof.SELECTED DRAWING: Figure 1 【課題】透明導電膜が形成された透明板を有するカバーによって表示部が覆われた中継信号機や線路表示器等の大型の鉄道用表示器において、電源設備の増強を行うことなく、着雪による表示部の視認性低下を防ぐ。【解決手段】鉄道用表示器１の表示部２ａは、所定間隔を空けて二次元的に広がるように配列された複数のランプ２２ａ〜２２ｇによって構成され、透明導電膜３５ａ〜３５ｃは、透明板３４における、複数のランプ２２ａ〜２２ｇのうち直線状に並ぶ第１ランプ群２２ｂ，２２ｄの前方部位と、第１ランプ群２２ｂ，２２ｄと隣り合いつつ当該第１ランプ群２２ｂ，２２ｄと平行に並ぶ第２ランプ群２２ｆ、２２ａ，２２ｇの前方部位とに、各ランプ群のランプ２２ｂ，２２ｄが並ぶ方向に延びる帯状となるよう設けられている。【選択図】図１
