PROBLEM TO BE SOLVED: To provide a signboard which gives an attention to a person seeing the signboard more than heretofore, and also is easily confirmed by the person even at night or from a distance by providing the commercial signboard with an instrument such as a thermometer capable of knowing the temperature at the spot. SOLUTION: In order to give a display function of the thermometer to the commercial signboard, the image of an alcohol tube of the thermometer is exhibited by a state of lighting of an LED display part 1 (claim 1) or is exhibited by a thin colored band material 2 (claim 2), wherein, the temperature is exhibited by a means driven by the control of a motor 4 via a reel 3. Both of the claims consider the installment of the signboard outdoors, are allowed to meet all weather and can be displayed even at night. COPYRIGHT: (C)2004,JPO&NCIPI
