PROBLEM TO BE SOLVED: To attract the attention of a purchaser and a peripheral person and to positively and effectively advertise only arbitrary article by varying an article sample from a regular state to a different state and stereoscopically informing the purchaser and the peripheral person of the existence of the article sample. SOLUTION: The solar battery 29 of a rocking device 18 incorporated in the article sample 15 is irradiated with light projected from a light source 12 through an opening part 11 formed in a display part 3 and an opening part 20 formed in the article sample 15 at the time of display. The solar battery 29 supplies the generated power to an electromagnetic coil 30 and generates a magnetic field between the electromagnetic coil 30 and a permanent magnet 32. A display object 19 is rocked rightward/leftward or forward/backward by rocking the article sample 15 or the display object 19. Thus, suction force and repulsion force repetitively operate in accordance with the rocking operation of a supporting board 31 when the permanent magnet 32 fitted to the supporting board 31 passes near the electromagnetic coil 30, and the display object 19 rocks rightward/leftward with the magnetic force.
