Abstract:
Provided are an optical waveguide capable of propagating light, and a position sensor and an optical circuit board including the same. The optical waveguide includes cores each partially formed in an S-shape. The S-shaped portion includes a first curved portion upstream as seen in the direction of light propagation, and a second curved portion downstream as seen in the direction of light propagation and curved in a direction opposite to the first curved portion. The first curved portion and the second curved portion are connected to each other via a straight portion having a length in the range of greater than 0 mm to 30 mm. One of the width of the exit of the first curved portion and the width of the entrance of the second curved portion is smaller than the width of a core portion upstream of the S-shaped portion.

Claim (Index 11):
A position sensor comprising:\n a sheet-like optical waveguide including a sheet-like core pattern member, and upper and lower sheet-like cladding layers holding the core pattern member therebetween, the sheet-like core pattern member including a lattice-shaped portion having a plurality of linear cores, a first outer peripheral core portion positioned on a first horizontal side and a first vertical side of an outer periphery of the lattice-shaped portion and optically connected to front ends of respective vertical cores of the lattice-shaped portion and to front ends of respective horizontal cores of the lattice-shaped portion, and a second outer peripheral core portion positioned on and extending along a second horizontal side and a second vertical side which are opposed respectively to the first horizontal side and the first vertical side, with the lattice-shaped portion therebetween, and extending from rear ends of the respective vertical cores of the lattice-shaped portion and from rear ends of the respective horizontal cores of the lattice-shaped portion; a light-emitting element connected to an end surface of the first outer peripheral core portion of the optical waveguide; and a light-receiving element connected to an end surface of the second outer peripheral core portion, wherein part of the optical waveguide corresponding to at least a portion of the second outer peripheral core portion is an optical waveguide as recited in  claim 1 , wherein light emitted from the light-emitting element passes through the first outer peripheral core portion, the lattice-shaped portion and the second outer peripheral core portion, and is received by the light-receiving element, wherein a surface portion of the position sensor corresponding to the lattice-shaped portion of the core pattern member serves as an input region, and wherein a pressed position in the input region is determined based on the amount of light propagating in the cores which is varied by the pressing.
