Abstract
Abstract A portable electronic apparatus includes an electronic main unit having a front surface, a rear surface, side surfaces, and a first electrical connector. The electronic main unit is served to perform arithmetic operation. The apparatus further includes a cover member provided on one of the side surfaces of the electronic main unit, for openably covering the front surface of the electronic main unit. The apparatus also includes an electronic sub-unit capable of being coupled with the electronic main unit. This electronic sub-unit has a support portion to be located behind the electronic main unit to support the rear surface, a handle portion projected from side of the electronic sub-unit for supporting the cover member when the cover member is opened, a second electrical connector capable of being connected to the first electrical connector, and an auxiliary electrical device capable of being cooperated with the electronic main unit.
