Title:
【発明の名称】EM-図形タブレット用スタイラスにおけるセグメント化したコアインダクタンス
Document Type and Number:
Japanese Patent JPH08511372
Kind Code:
A
Abstract:
A graphical tablet and a stylus interact electromagnetically with one another. The stylus includes a coil and a transducer to affect an inductance of the coil in response to a force exerted on a tip of the stylus. The transducer comprises first and second ferrite cores. The cores are mounted to move with respect to one another in response to the force. The cores are substantially in contact with one another in the absence of the force. Disengaging causes a well detectable jump in the inductance.
