Stylus Pen Holder on Notebook PC

      Disclosed is a device of a stylus-pen holder mounted on
Notebook PC.  A motion of just pushing can make the pen "Ready to
use" Position (The pen stands up) from "Housing" Position so that
even handy-capped person can easily use it.  The device dose not have
complex parts that may cause a out of order by a hard shock.  The
whole mechanism dose not require much space.  The device is widely
applicable to Notebook PCs with Pen function.

      Drawing shows how the device works.  At "Housing" Position,
clip finger "a" and "b" hold a pen with holding force Fa and Fb
separately.  Fb must be enough smaller than Fa to release a pen when
left end of pen is pushed.  When the pen is pushed farther, left end
of pen goes down into Area C.  Width of Area C gradually goes narrow.
And the holding force Fc increase in responding to distance that pen
goes down.  Finally moment of Fc*L1 goes equal to M*L2.  And the pen
stands.  The actions actually happens in a very short time during
pushing motion And the elasticity of plastic parts bring the holding
force.  Then the actions are very smooth.

      Key part of the device is a clip "A".  The precise design
enables the function.  But it dose not require much space, because
the shape of the part is like a letter "U".  Then the devise could be
mounted even on a notebook PC.
