Abstract:
1. An information processing apparatus, comprising: a main body section having a first face defined by a plurality of sides and having a keyboard disposed thereon and a second face which shares one of the sides of said first face; a display section having a third face on which a screen is disposed; and a hinge mechanism including a first shaft structure provided in an exposed state on said second face of said main body section, a second shaft structure provided on said display section and a shaft connection section adapted to connect said first shaft structure and said second shaft structure to each other, said hinge mechanism pivotably connecting said display section to said main body section between a first position at which said third face of said display section is opposed to said first face of said main body section and a second position at which said third face is inclined by a first predetermined angle with respect to said first face such that the center of the pivotal motion of said display section varies in response to the pivotal motion of said display section, said first shaft structure includes a first shaft and a second shaft having axes whose positions are displaced from each other, said second shaft structure includes a third shaft and a fourth shaft having axes whose positions are displaced from each other, said shaft connection section includes a first arm adapted to connect said first shaft and said third shaft to each other and a second arm adapted to connect said second shaft and said fourth shaft to each other, and the distance between the axes of said first shaft and said second shaft and the distance between the axes of said second shaft and the fourth shaft are different from each other, and the axes of the first shaft, the second shaft, the third shaft and the fourth shaft are positioned so as to obtain a desired locus of pivotal motion of the display section, said desired locus of pivotal motion obtained from a first circle having a first radius and centered at an axis position of the first shaft and a second circle having a second radius and centered at an axis position of the second shaft, in which the first radius is different from the second radius.
