<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus with fewer number of terminals for non-contact charging, and capable of being charged effectively. <P>SOLUTION: A portable telephone 1 comprises a battery charger 42. The battery charger 42 includes: a non-contact charging coil 47 for receiving electromagnetic waves with prescribed frequency coming out of an outer device and for generating electric power by electromagnetic induction using the received electromagnetic waves; a circuit part 46 for applying prescribed processing for the electric power generated by the non-contact charging coil 47; a battery side power supply terminal 43a for which power supply voltage can be provided; a battery side identification terminal 43b for which identification voltage for identifying a connection to the battery charger 42 can be provided and for which non-contact charging identification voltage for identifying non-contact charging can be provided; a battery side ground terminal 43c; and a FET 48 for switching between an on-state and an off-state, in which the on-state enables the non-contact identification voltage to be provided for the battery side identification terminal 43b, while the off-state does not let the non-contact identification voltage be provided for the battery side identification terminal 43b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
