Abstract: Disclosed is a three-dimensional advertisement device. The present invention includes: a frame having a predetermined shape; a plurality of unit cells supported by the frame and arrayed in an X-Y matrix; and a controller for selectively driving the unit cells according to an external input signal, wherein the unit cell includes: a cell plate having a magnet on a rear surface thereof and having an upper end hinge-coupled to the frame, the cell plate being vertically disposed; and an electromagnet arranged to face the magnet of the cell plate to enable the cell plate to rotate forward when power is applied thereto according to a signal of a controller. The cell plate of the unit cells includes a reflection plate such that advertisement text is three-dimensionally expressed through a combination of the cell plates which rotate to be opened.

Abstract: The present invention relates to a bicycle-type game simulation device comprising: a crank pedal unit; a swing footrest horizontally rotatably installed in the crank pedal unit; a swing detection means which detects a left-and-right rotation of the swing footrest and transmits a signal thereof; and a forward-and-backward rotation detection means which detects a forward/reverse rotation of a crank shaft and transmits a signal thereof, wherein a user can easily operate a behavioral motion of a player in a game with his/her foot, using the mechanism of a crank pedal of a bicycle, so that the user can perceive a good sense of reality.
