A light source module including a light source assembly and a light converging element is provided. The light source assembly provides an illumination beam and the light converging element is disposed on a transmission path of the illumination beam. The light converging element has a top end and a bottom end opposite to the top end. The light converging element is gradually reduced from the bottom end to the top end. The top end is opposite to the light source assembly and has a cavity. The illumination beam is incident into the light converging element from the cavity and exits the light converging element from the bottom end. The illumination beam is converged by the light converging element, so the diverging angle of the illumination beam provided by the light source module is relatively small.

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.

An optical pointing device for detecting a displacement between the optical pointing device and a working surface includes a casing, a light emitting component and a light sensing component. The casing includes a transparent element. A light emitting hole is defined through the casing and located at the same side with the transparent element. The light emitting component is located inside the casing and emits a light beam. The light beam passes through the light emitting hole and is reflected by the working surface to pass through the transparent element. The light sensing component is located inside the casing. The transparent element is located between the light sensing component and the working surface to cover the light sensing component. The light sensing component has a light sensing surface configured for sensing the light beam reflected by the working surface.

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.
