PURPOSE:To make the indicated temperature on an alcohol thermometer at the canopy of the main casing easier to read in an indication system showing thereon the temperature detected by a sensor in the storage space. CONSTITUTION:Under the canopy 11 fluorescent lamps 12 are installed as means of illuminating the front part of a display case. In a partition 13 provided between the fluorescent lamps 12 and an alcohol thermometer 72 lighting windows 15 are formed so as to send therethrough the light of the fluorescent lamps 12 to the alcohol thermometer 72. By thus illuminating the alcohol thermometer 72 from behind the liquid sealed in, the graduations, etc., are made to stand out and become easier to read. |
