NON-CONTACT CHARGING DEVICE, CHARGER, CORDLESS DEVICE AND NON-CONTACT CHARGER

摘要

PROBLEM TO BE SOLVED: To enable mutual induction to be efficiently performed with a proper gap, by avoiding complex structures for the coil and mounting and by using an induction coil of low cost and good productivity. SOLUTION: A capacitor is connected in parallel to the primary induction coil 15 of a charger 1 and to the secondary induction coil 112 of a cordless device (slave device) 100 to constitute an LC-parallel resonance circuit each in the charger 1 and cordless device 100. The primary induction coil 15 and the secondary induction coil 112 are each made up of a sheet coil. These sheet coils are fixed and arranged in the charger 1 and the cordless device 100, so as to face each other with a given gap in a charging state, when the cordless device 100 is set onto the charger 1.
