<p>PROBLEM TO BE SOLVED: To provide a power supply device, which can cope with input voltage of each country, and can charge contactlessly a power source having multi- outputs and a handset; which simplifies the circuit structure, reduces the number of parts, and improves the efficiency. SOLUTION: In the power supply device for a telephone set provided with a handset and a main phone having a charger which charges the handset contactlessly, the power supply of the battery charger and a plurality of DC output power supply which is necessary for the main phone are constituted of one transformer. The transformer is arranged, by loosely connecting charger coils disposed at the ends of two magnet legs of a U-shaped core, with a plurality of output coils disposed in the magnet center.</p> |
