<P>PROBLEM TO BE SOLVED: To allow a battery to be replaced without stopping operation of an electronic apparatus. <P>SOLUTION: According to an embodiment, there are provided a battery switching circuit configured to feed a load circuit by switching between a battery unit 1 and a battery unit 2, and an electronic apparatus. The battery switching circuit comprises: a FET 12 which controls feeding by the battery unit 1; a FET 22 which controls feeding by the battery unit 2; a photorelay 14 which controls the FET 12 with a gate voltage; a photorelay 24 which controls the FET 22 with a gate voltage; and a switch 41 which causes the photorelay 14 and the photorelay 24 to switch one of the FET 12 and the FET 22 to ON state and to switch both of the FET 12 and the FET 22 to ON state during state transition to the ON state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
