ABSTRACT:
A coordinate inputting apparatus which facilitates minimization and a keyboard apparatus which facilitates minimization and is superior in operability are disclosed. A pointing device includes a base including a pedestal in the form of a flat plate and a columnar member in the form of a quadrangle prism provided uprightly on the pedestal, strain gauges fixedly adhered to four outer side faces of the columnar body, a flexible cable connected to each strain gauge, and a cap mounted at the top of the columnar member. The pointing device is secured to a metal plate in the inside of a keyboard inputting apparatus such that the cap projects upwardly farther than the top face of a housing of the keyboard inputting apparatus and is located between different key tops of key switches of the keyboard inputting apparatus.
