摘要

A portable data-processing system includes a box-shaped housing having a side and a receptacle opening at the side, a first pack-shaped component removably fitted in the receptacle, and a second pack-shaped component which can be removably fitted in the receptacle in place of the first pack-shaped component. The pack-shaped component has a first part and a second part. The first part is to be removably fitted in the receptacle. The second part is a hollow cylindrical member and is to extend outside the housing and along the side of the housing. The pack-shaped components may be battery packs with the second pack-shaped component having a greater ampacity than the first pack-shaped component. The housing includes a pen receptacle for storing a stylus pen. The second pack-shaped component includes an engagement member which engages the pen receptacle and a pen-holding section for storing the stylus pen.
