PURPOSE: To facilitate the altering of the layout of a game apparatus by arranging a drive wheel on the bottom surface of the main body of the game apparatus to move the main body of the game apparatus rolling rotating over a floor and a mechanism adapted to change the direction of the main body moves by chancing the direction of the drive wheel while a remote control thereof is made.

CONSTITUTION: A game apparatus 20 is supported on a floor 14 with casters 25-1-25-4 and a drive wheel 32. Then, by the operation of an operation unit 46, a motor drive circuit 35 is controlled through a receiving section 45 to drive or control a moving device 30. A crown gear 40 is controlled to drive a gear part 31b. As a result, the drive wheel 32 moves forward or backward while it makes a change in direction. This enables the altering of the layout of the game apparatus 20 by a remote control viewing the position thereof from a distant position.
