Kind Code:
B2
Abstract:
PURPOSE:To transmit the change information of a working state corresponding to the intention of an operator by varying the inductance of a coil with stress applied on a core. CONSTITUTION:When an operation is performed by holding a cabinet 1 with a finger, etc., and pressing the tip of the main body part 6a of a pen 6 on the input plane of a tablet, etc., the stress corresponding to pen pressure at that time is applied on the core 2 via the pen 6. Thus, when the stress corre sponding to the pen pressure is applied on the core 2 via the pen 6, the permea bility of the core 2 is changed, and the inductance of the coil is changed. In such a way, the tuning frequency of a tuning circuit 7 is changed corresponding to the pen pressure, and the change information is transmitted to the tablet, etc. Also, at this time, the core 2 itself is scarcely deformed, and an operating stroke is nearly zero, therefore, it follows that the change information corre sponding to an operating sense can be transmitted.
