Patent ID: 8743088

Claim:
A pointing device, comprising: a touching surface on which an object is placed; a light emitting element for illuminating the touching surface from a side opposite to a side where the object is placed; and an imaging element for receiving light reflected from the object, the pointing device further comprising a first light control part subduing a deviation in a distribution of a light intensity on the touching surface by controlling light which is emitted from the light emitting element and reaches the touching surface, and a second light control part absorbing light which does not contribute to illumination of the touching surface out of the light emitted from the light emitting element; the light emitting element emitting light whose light intensity is deviated with respect to a radiation angle, and the first light control part and the second light control part being positioned on a light path from the light emitting element to the touching surface, wherein the light emitting element is covered with a first resin section, the first light control part is provided on a first surface of the first resin section, and the first light control part diffuses light emitted from the light emitting element and is designed such that an interface on the light path has a bump structure, the bump structure having concavities and convexities repeated periodically which scatter light reaching the bump structure, and the second light control part is provided on a second surface of the first resin section.
