Abstract
A portable computer comprises a base unit to which a keyboard and a display unit are attached. First and second batteries, functioning as a drive power source, are attached to the base unit. An optional component may be attached to the base unit in place of the second battery. The optional component, for example, can be a modem device to be connected to a telephone line or an additional memory unit. In the base unit, there is formed a first mounting recess to which the first battery is detachably attached, and a second mounting recess to which the second battery or the optional component is selectively detachably attached. A connector as provided entirely within the base unit to permit connection to the component mounted in the second mounting recess. When the optional component is mounted in the second mounting recess, an adaptor interconnects the connector and the optional component.
