To provide a new configuration to warm a translucent case of an optical sensor unit mounted on a laser-guided transportation vehicle for a cold storage warehouse.SOLUTION: An optical sensor unit 3 is mounted on a laser-guided transportation vehicle for a cold storage warehouse. The unit 3 comprises a light projection part 41 to emit a laser beam and a light receiving part 42 to receive a reflected laser beam. The unit 3 comprises a rotary driving part to horizontally rotate the light projection part 41 and the light receiving part 42, and a cylindrical translucent case 44 to cover the area around the light projection part 41 and the light receiving part 42. The unit 3 comprises at least one of heaters 5 [5(a), 5(b), 5(c)] to radiate heat for warming the outside surface of the translucent case 44. The heater 5 is annular and plate-shaped. The heater 5 surrounds the translucent case 44, does not touch the translucent case 44, and is horizontally placed at the different height from the light projection part 41 and the light receiving part 42.SELECTED DRAWING: Figure 4

    【課題】冷凍倉庫用のレーザ誘導方式の搬送車に搭載される光学センサユニットの透光ケースを温める新規な構成を提供する。【解決手段】光学センサユニット3は、冷凍倉庫用のレーザ誘導方式の搬送車に搭載される。当該ユニット3は、レーザ光を投光する投光部41と、反射されたレーザ光を受光する受光部42とを備える。当該ユニット3は、投光部41および受光部42を水平に回転させる回転駆動部と、投光部41および受光部42の周囲を覆う筒状の透光ケース44とを備える。当該ユニット3は、透光ケース44の外面を温めるために熱を輻射する少なくとも1つのヒータ5[5(a),5(b),5(c)]を備える。ヒータ5は、環状かつ板状である。ヒータ5は、透光ケース44を囲み、透光ケース44に接触せず、かつ、投光部41および受光部42とは異なる高さに水平に配置されている。【選択図】図4
