OPTICAL POINTING DEVICE WITH INTEGRATED OPTICAL COMPONENTS AND RELATED ELECTRONIC APPARATUS
First Claim
1. An optical pointing device comprising:
- a cover comprising a transparent part where light passes through;
a sensing component installed inside the cover, the sensing component comprising;
a light emitting module for emitting light; and
a light sensing module for sensing light transmitted from the transparent part so as to generate a corresponding sensing signal; and
a light guiding component installed between the sensing component and the cover, the light guiding component comprising;
a reflecting part for reflecting the light emitted from the light emitting module to the transparent part; and
a condensing part integrated with the reflecting part monolithically for condensing light transmitted from the transparent part to the light sensing module;
wherein the light emitted from the light emitting module is reflected to the transparent part by the reflecting part and then reflected back to the transparent part and the condensing part by a shelter disposed above the cover, and the condensing part is for condensing the light transmitted from the transparent part to the light sensing module.

Abstract
According to the claimed invention, an optical pointing device includes a cover having a transparent part, and a sensing component installed inside the cover. The sensing component includes a light emitting module for emitting light, and a light sensing module for sensing light transmitted from the transparent part. The optical pointing device further includes a light guiding component installed between the sensing component and the cover. The light guiding component includes a reflecting part for reflecting the light emitted from the light emitting module to the transparent part, and a condensing part integrated with the reflecting part monolithically for condensing light transmitted from the transparent part to the light sensing module. The light emitted from the light emitting module is reflected to the transparent part by the reflecting part and then reflected back to the transparent part and the condensing part by a shelter disposed above the cover.
