Patent ID: 7630600

Claim:
A touch panel optical waveguide device comprising: a plurality of light emitting cores provided on a surface of an elongated base and extending in juxtaposed relation from a predetermined longitudinally middle portion of the base toward one of opposite ends of the base, and each having a proximal end and a distal end; a plurality of light receiving cores provided on the surface of the elongated base and extending in juxtaposed relation from the longitudinally middle portion of the base toward the other end of the base, and each having a proximal end and a distal end; the proximal ends of the light emitting cores being spaced from the proximal ends of the light receiving cores by the longitudinally middle portion of the base; the distal ends of the light emitting cores and the distal ends of the light receiving cores being positioned on one longitudinal side edge of the base; an over-cladding layer provided on the surface of the base except for the longitudinally middle portion as covering the light emitting cores and the light receiving cores; and a mount member including light emitting means and light receiving means fixed to a single substrate; the mount member being fixed in a recess defined on the longitudinally middle portion of the base; the light emitting means being opposed to proximal end faces of the light emitting cores; the light receiving means being opposed to proximal end faces of the light receiving cores.
