PROBLEM TO BE SOLVED: To enable stable operation to be conducted irrespective of a variety of condition changes at battery driving. SOLUTION: This electronic apparatus is a liquid crystal display driven by the battery, and comprises: the battery 1; a voltage detection circuit 27 that detects an output voltage value VM from the battery 1; a regulator circuit 3 that converts an output voltage of the battery 1 to a proper voltage; a drive circuit 5 connected to an output of the battery 1; and a switch means 15 that switches whether to directly feed a voltage fed from the battery 1 to the drive circuit 5 from the battery 1, or to feed the voltage through the regulator circuit 3. The switch means 15 is switched depending on an output voltage of the voltage detection circuit 27. COPYRIGHT: (C)2004,JPO&NCIPI
