Pointing device for controlling cursor movement on display
First Claim
1. A pointing device having a stick member for controlling cursor movement on a display, the pointing device comprising:
- piezoelectric means comprising piezoelectric elements arranged in the stick member, the piezoelectric means converting a stress exerted to the stick member into a voltage; and
control means for controlling cursor movement corresponding to an outputting state of the voltage converted by the piezoelectric means.

Abstract
Disclosed is a pointing device 1 including; a stick member 11 depressed by an operator; piezoelectric elements 13 each of which converts a stress exerted to the stick member 11 into a voltage; a voltage converting circuit 15 connected to the piezoelectric elements 13; a control part 19 to which a signal from the voltage converting circuit 15 is input and which transmits a signal for controlling cursor movement to a system board 17. The control part 19 detects the voltage produced in the piezoelectric elements 13 based on the signal from the voltage converting circuit 15 and stores such voltage as a hold value in a RAM 27. Further, the control part 19 transmits the signal for controlling cursor movement to the system board 17.

15. A pointing device having a stick member for controlling cursor movement on a display, the pointing device comprising:
-
piezoelectric elements arranged in the stick member, each of the piezoelectric elements converting a stress exerted to the stick member into a voltage; a voltage converting circuit for converting the voltage produced in the piezoelectric element into a digital signal corresponding to the voltage; a control part having a memory for detecting the voltage based on the digital signal from the voltage converting circuit and storing the detected voltage in the memory; and a system board for controlling cursor movement on the display based on an electric signal corresponding to the voltage stored in the memory.
