Electronic stylus type optical reader |
摘要 |
An electronic stylus, for use with a computer having a digitizer, has a light emitter for emitting light to illuminate optically encoded information. A photodetector senses light reflected from the illuminated optically encoded information and produced an electrical signal representative of the optically encoded information. Stylus electronics provide positional input data by contacting a digitizer tablet with the stylus. The stylus housing contains the light emitter, photodetector and stylus electronics. A tip at a fore end of the housing is adapted for contact with the digitizer tablet and the light is emitted from other than the fore end of the housing.
