The information processor is provided with rotatable and freely axially movable function knob 15. The information processor is further provided with a control part 205 which selects first information included in the first layer by rotation of the function knob 15, selects second information included in the second layer and related to the first information by depressing and rotating the function knob 15, and reads the second information by releasing the depression of the function knob 15 (step S12 to S19). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
