PACK DEVICE, SENSE TABLE MANAGEMENT DEVICE, MOVING LOCUS CALCULATION METHOD, MOVING LOCUS CALCULATION PROGRAM AND RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2005275760
Kind Code:
A
Abstract:
To commonize a resonance frequency of a coil Z without reducing coil detection performance.
Two coils A, B having the same resonance frequency are used so as to detect a position and a rotation angle, and one coil Z having a resonance frequency different from the coils and having the resonance frequency common to all packs is mounted in the vicinity of the center of the pack so as to detect a rotation direction. The rotation angle is set as a relative angle from positions of the coils A, B after movement and positions before the movement, and the rotation direction is determined by detecting the side on which of the right and left sides the coil Z is present to a diagonal connecting two coil centers in a non-pressed-down state of a button.
