Convertible Personal Computer Mouse

      A method of combining two types of the personal computer mouse
into one mouse is disclosed.  A lever is used to switch between the
conventional type of mouse and the track-ball type of mouse.

      Currently there are two basic types of a personal computer
mouse, each having advantages and disadvantages.  Our solution to the
disadvantages of each mouse type separately is to combine the two
types.  The user could then easily switch from one type to another
depending on what was best for the application.

      The first type of mouse is the standard mouse that has to be
moved on a surface to move the mouse pointer on a personal computer
screen.  The second type of mouse is commonly referred to as a
track-ball.  A ball is moved by the user's hand in order to move the
mouse pointer.

      The standard mouse has the disadvantage that it requires desk
space in order to move the mouse.  The advantage is that it is faster
and more accurate.

      The track-ball has the disadvantage that it slower and less
accurate.  The advantage is that it does not take up much desk space.

      These two types can be combined into one mouse.  A lever or
button can be used to switch between one type or the other.

mouse buttons are shown as A.  The main body of the mouse is shown as
