摘要： An optical touch apparatus includes a first light source, a second light source, a light guide device, a light reflecting device and an image sensing module. The first light source emits first light beam which travels within the light guide device and is reflective by an object close to or in contact with a surface of the light guide device to become a first image light beam. The first image light beam is reflected by a light reflecting device. The image sensing module receives the first image light beam. The second light source emits a second light beam, wherein when the optical touch apparatus moves on a working surface, the second light beam is reflective by the working surface to form a second image light beam which is received by the same image sensing module.

摘要： An optical scrolling module includes a prism, a light source, an image sensor and a first condenser. The prism is disposed at an opening of an upper shell of a mouse and has a light incident surface, a reflective surface, a contact surface and a light emitting surface. The contact and light incident surfaces are respectively connected between the reflective and light emitting surfaces. The contact surface is exposed by the opening. A light beam from the light source is transmitted to the contact surface via the light incident and reflective surfaces. When an object with a pattern structure puts on the contact surface, the light beam is scattered and a portion of the light beam is transmitted to the image sensor via the first condenser. When the object is removed from the contact surface, the light beam is reflected to the light emitting surface by the contact surface.

摘要： An optical pointing device including a light source, an optical transfer assembly, a light beam splitter, and an image sensor is provided. The light source provides an illumination light beam. The optical transfer assembly concentrates the illumination light beam. The light beam splitter is disposed on a transmission path of the illumination light beam for splitting the illumination light beam into a first light beam and a second light beam. The image sensor is capable of sensing the first and the second light beams. When the optical pointing device is used on a reflective surface, the first light beam is reflected to the lens by the reflective surface and then is received by the image sensor; when the optical pointing device is used on a transparent body above the reflective surface, the second light beam would be received by the image sensor.
