<p>PROBLEM TO BE SOLVED: To provide a pointing device for a foot that operability is excellent, faults and deficiencies are not caused because wiring, an electronic part and a mechanism part are also prevented from being seen from the outside and the miniaturization is attained. SOLUTION: Elastic bodies 36 and 38 returning a foot placing part 32 to its initial position against the power of a foot are provided between a 2nd moving part 30 and the part 32, and the part 32 is held at the initial position until the power of the foot which attempts to turn the part 32 becomes equal to or larger than fixed magnitude, and the contacts of switches 46 and 48 are switched over when the part 32 are turned two or more times from the initial position.</p> |
