PROBLEM TO BE SOLVED: To fix a display medium to a surface on which the display medium is placed and to easily attach/detach the display medium in its attachment/detachment.SOLUTION: When a magnet 22 faces a magnet 12A and a magnet 15A, repulsion occurs between the magnet 22 and the magnet 12A, and a clearance is generated between a lid part 1B and a display 2. Repulsion also occurs between the magnet 15A and the magnet 22. When the magnet 22 faces a magnet 12C and a magnet 15C, attraction occurs between the magnet 22 and the magnet 12C. Attraction also occurs between the magnet 15C and the magnet 22. When attraction occurs between the magnet 22 and the magnet 12C and between the magnet 22 and the magnet 15C, the display 2 is brought into tight contact with a body part 1A by the attraction and the lid part 1B is brought into tight contact with the display 2. |
