<p>PURPOSE:To provide a mobile object which can effectively serve as a computer soft input device of a multi-dimensional coordinate system by using a switch, etc., in order to detect the direction of the revolution of a spherical body when the spherical body revolves backward or forward and leftward or rightward. CONSTITUTION:Two or four pushing parts 18 are provided on a rod 14 hanged from the upper part of a spherical body 9 in order to push a mobile object 15 and the switches 17. When the body 9 is tilted, the object 15 is turned toward its gravity direction. Meanwhile the parts 18 generates the pressure based on the tilting angle of the body 9 set to the each switch 17, the weight of the object 15, and the position set from a fulcrum 28 of the parts 18. Each switch 17 is turned on when the pressure received from the part 18 reaches such a degree that actuates a contact. Then two parts 18 and two switches 17 are used when the revolution of the body 9 is detected only in its uniaxial direction. Meanwhile four parts 18 and four switches 17 are used when the revolution of the body 9 is detected in its biaxial directio respectively.</p> |
