Abstract

PURPOSE:To always obtain a satisfactory camera visual range by providing an attaching cover with a heater and disposing a low-heat conductivity material between the attaching cover and an enclosure, thereby removing water stuck to a cover glass or easily melting and removing ice, etc., stuck to the cover glass. CONSTITUTION:A cover heater 15 is provided on the rear face side of a front cover 14, and the front cover 14 is fixed to an enclosure 11 while pinching a heat insulating material 16. A glass heater 17 where a metal is vapor-deposited is provided on the rear face of a protective glass 13, and the glass 13 is inserted to a groove part 11a of the enclosure 11 while pinching a seal material 18 and fixed to the enclosure 11 by the front cover 14. By energizing the glass heater 17, the protective glass 13 is heated and by energizing the cover heater 15, the front cover 14 is heated. Thus, the quantity of heat is considerably increased, and ice, snow, or the like is efficiently and easily melted in the case of sticking, ice or snow and a satisfactory field of view for camera is always obtained.
