1. An input device for a computer comprising:
- a movable body which displaces upon receipt of a load in a two-dimensional direction;
a fixed light emitting element for emitting light; and
a light receiving element for receiving an image of the light from the fixed light emitting element, the image of light shifting in association with displacement of the movable body,wherein the movable body, the fixed light emitting element, and the light receiving element are integrally formed and wherein a unitary movable section of the movable body encloses the fixed light emitting element and the light receiving element such that all light from the fixed light emitting element and to the light receiving element travel within the unitary movable section.

Abstract
The input device which includes a reflection type optical sensor having light emitting means and light receiving means; an operation section disposed facing the optical sensor, the operation section being tilted when a load is applied thereto; and output means for detecting a tilt status of the operation section based on signals from the light receiving means and outputting detected results to a computer body as positional information.

12. An input processing method for an input device for a computer, comprising:
-
detecting a shift of an image of light emitted from a light emitting element and shifting in association with a displacement of a movable body; simultaneously determining from the shift of the image of light vectors in two directions crossing each other at right angles corresponding to a direction and amount of the displacement; and synthesizing the vectors in the two directions to obtain a synthesized vector and calculating a direction and amount of operation from the synthesized vector. - View Dependent Claims (13, 14, 15)
