Abstract
The battery accepting unit for a battery operated electric/electronic apparatus includes a plurality of positive terminals and a plurality of negative terminals. The battery accepting unit has a first position whereat a battery is connected by a pair of positive and negative terminals; a second position whereat a battery is connected by another pair of positive and negative terminals; a third position that can serve as both said first and said second positions; and a fourth position whereat a battery is connected by all positive and negative terminals. According to the battery accepting unit of the present invention, a battery pack can be exchanged without halting the power supply to an electric/electronic apparatus. Since an auxiliary power source, such as a sub-battery, is not required for an electric/electronic apparatus, a single power system, including a DC/DC converter and a charging circuit, can be provided. Therefore, the electric circuit in a system can be simplified, space can be saved inside a box, and manufacturing costs can be reduced.
