Claim:
1. A furniture having a wireless charging capability, the furniture comprising: a plurality of transmission coil units disposed distantly from each other on the same plane of a flat plate of the furniture; and a central transmission controlling unit, wherein the central transmission controlling unit selects at least one transmission coil unit where a wireless power reception apparatus is placed, and transmits a wireless power signal through the at least one transmission coil unit, and wherein the central transmission controlling unit is separably installed from the plurality of transmission coil units, wherein the central transmission controlling unit and the plurality of transmission coil units are connected to a cable, wherein the plurality of transmission coil units are installed in parallel with each other on an upper surface of the flat plate, wherein the central transmission controlling unit is installed on a lower surface of the flat plate, and comprises: an object sensor unit; a switching controller; and a transmission controller, wherein the object sensor unit senses a variation in one of a current and an voltage in the plurality of transmission coil units to generate an object sensing signal, wherein the switching controller turns on and off supplying of a power to the plurality of transmission coil units respectively, and wherein the transmission controller selects the at least one transmission coil unit where the wireless power reception apparatus is placed, based on the object sensing signal from the object sensor unit, and controls the switching controller to control a switching unit to transfer a driving signal to the at least one transmission coil unit.
