ABSTRACT:
An electronic device (21) switches its operation mode in accordance with the type of an installed battery pack (22). The battery pack (22) has a regulator (222), a specification-discriminating terminal (TJ), and a resistor (224), connected between the regulator (222) and the specification-discriminating terminal (TJ) and having a resistance corresponding to the specification of the incorporated battery (221). The electronic device (21) has a monitor resistor (214) connected between a terminal (TL) connected to the specification-discriminating terminal (TJ) of the battery pack (22) and ground, a discriminating circuit (212, 215, 216) for detecting a monitor voltage generated across this monitor resistor (214) to discriminate the specification of the battery (221), and a switch controller (212, 219) for switching the operation mode in accordance with the specification discriminated by the discriminating circuit (212, 215, 216).
