Abstract
A portable information processing apparatus which is a lap top type has a housing with a hard disk drive At the bottom side of the housing a first touch sensor is provided adjacent a corner and a second touch sensor is provided adjacent a corner which is at a diagonal side. Once the portable information processing apparatus leaves a table, output signals of the respective touch sensors and vary precisely. By comparing the output signals of the respective touch sensors and with a true value table memorized in a memory, it is decided whether the portable information processing apparatus has started dropping. If the portable information processing apparatus starts dropping, the hard disk drive enters the withdrawal mode.
