Stylus devices responsive to pressure changes for use in videographic and like apparatus |
摘要 |
A stylus device for use in a videographic apparatus, includes a housing with a projecting stylus. In operation, pressure changes cause movement of the resiliently mounted stylus. This carries a magnet which co-operates with a Hall Effect transducer such that the pressure variation is converted into signal changes by the transducer. A moveable carrier allows the transducer to be moved to adjust the preload pressure in the stylus together with the preload out-put of the transducer.
