PROBLEM TO BE SOLVED: To solve the following problems in a conventional method: for decoration of stairs or the like and advertisement on stairs, a sheet with an adhesive is cut into the height of a step and stuck on a riser and, when an event is over and the sheet piece is peeled off, the sheet piece cannot be reused and the sheet must be printed again for a similar event taking place later, which results in the waste of labor, time, and expense and, if the step part is made of a material on which the sheet cannot be stuck, the stair decoration or advertisement has to be given up. SOLUTION: Attaching and detaching of a sheet piece on which prescribed information is formed is carried out by making use of a magnet. Specifically, a magnet is fitted on the sheet piece on which prescribed information is formed, and the sheet piece is fitted to the steel of the stair side, and vice versa. In this way, attaching/detaching can be easily carried out any number of times. Also, since the sheet piece on which prescribed information is formed can be used any number of times, waste of labor, time, and expense can be eliminated. COPYRIGHT: (C)2011,JPO&INPIT
