Abstract
A stylus pen for use as a computer input device includes a pen holder with an associated tip, a chamber defined in the pen holder and filled with a non-compressible fluid, a pressure sensor having a pressure receiving surface that detects pressure in the chamber, and a means for converting a mechanical force applied to the tip to a change in pressure of the non-compressible fluid enclosed in the chamber. In the use of the pen a mechanical force applied to the tip changes the pressure of the non-compressible fluid; and this pressure change is detected by the pressure sensor to produce a change in the output signal from the sensor usable as a computer input.
Claims17
A stylus pen comprising:
- a pen holder with an associated tip;
- a chamber contained in the pen holder and filled with a non-compressible fluid;
- a pressure sensor having a pressure receiving surface that detects pressure in the chamber;
- and,
- a means for converting a mechanical force, applied to the tip, to a change in pressure of the non-compressible fluid enclosed in the chamber.
A stylus pen comprising:
- a pen holder;
- a shaft which is slidably inserted in the pen holder and has a tip projecting out from a front end of the pen holder;
- a piston integrally provided on a rear end of the shaft;
- a chamber having a flexible member which is deformed by the piston when a mechanical force is applied to the tip, said chamber being filled with a non-compressible fluid;
- and,
- a pressure sensor that detects the pressure of the non-compressible fluid contained in the chamber to issue an output in accordance with the detected pressure.
An inputting method of a stylus pen having a pressure sensor, comprising the steps of:
- converting a mechanical force applied to a tip of a stylus pen to a change in pressure of a non-compressible fluid contained in a closed chamber;
- and,
- transmitting the pressure change to the pressure sensor.
