초록 ▼

A power supply arrangement for a main unit of a portable, battery operated information processing apparatus including at least a microprocessor and a battery. The power supply arrangement comprising an expansion unit for the portable information processing apparatus for expanding the operation capability of the main unit of the information processing apparatus upon connection therewith. The expansion unit includes a power circuit for converting an a.c. voltage to a d.c. voltage, the power circuit enabling supply of power to the main unit when the expansion unit is connected with the main unit. Also, a connection arrangement is provided for the expansion unit and main unit.
