To provide a guide indicator which is installed in such a platform of a station which receives direct sunlight, or the like, and which can display guidance information in an easily visual manner and furthermore in which the occurrence of trouble in equipment due to dust, iron powder, rainwater or the like is prevented and the equipment can operate without problem even when receiving heat due to heat generation thereof and direct sunlight.SOLUTION: Electronic equipment such as a liquid crystal display is housed inside a housing and the inside of the housing is formed into a sealed space, furthermore a heat exchanger causing ambient air to pass through a housing central part is provided, heat is radiated by causing the ambient air and air inside the housing to orthogonally flow to perform heat exchange, and the back surface of the liquid crystal display is cooled by flow of a fan which sucks internal air from the heat exchanger.SELECTED DRAWING: Figure 3 【課題】直射日光が当たるような駅のホームなどに設置する案内表示器において、案内情報を見易く表示した上で、埃や鉄粉、雨水などで機器に支障が生じることを防ぎ、機器の発熱と直射日光による熱を受けても機器が問題なく稼働できるようにすること。【解決手段】液晶ディスプレイなどの電子機器を筺体内に収めて、その筺体の内部を密閉空間にした上で、筺体中央部に外気を通過させる熱交換器を設け、外気と筺体内の空気を直交して流して熱交換を行うことで放熱し、熱交換器から内部空気を吸い出したファンの流れによって液晶ディスプレイの背面を冷却する。【選択図】 図３
