PROBLEM TO BE SOLVED: To integrate a stage floor display device and a platform call button in simple structure and install them in a short period of time without processing an installation surface. SOLUTION: A stage floor display device 5 is set by dividing a platform call button 7 into a piezoelectric switch 7d for detection and a call registration lamp 7c, and a stage floor indication lamp 6 and the call registration lamp 7c are structured to adhere a thin laminated body of a back surface electrode 6c, an insulated layer 6d, a luminous layer 6e and a transparent conductive film 6f. Consequently, it is possible to easily install it in a short period of time without applying processing on the installation surface as it is a flat plate type thin stage floor display device, and it is possible to improve workability. |
