Abstract
It is possible to enable a pointer to execute a shifting operation input and a clicking operation input by use of a common type pressure-sensitive pointing device provided with an x-axis strain sensor and a y-axis strain sensor. A pressure-sensitive pointing device () is provided with strain sensors (), (), () and (). A voltage corresponding to the strain along the x-axis direction, and a voltage corresponding to the strain along the y-axis direction are outputted from nodes (), () and (), respectively. The voltage corresponding to the strain along the x-axis direction, and the voltage corresponding to the strain along the y-axis direction are inputted alternately to an operational amplifier () by switches (SW) and (SW) when a switch (SW) is in an ON-condition. The voltage corresponding to the strain along the z-axis direction is inputted to an operational amplifier () when the switch (SW) is in an OFF-condition. Respective outputs of the operational amplifiers (), () are alternately inputted to an ADC () by switches (SW) and (SW) and processed in a digital processing circuit.
