Abstract: An optical touch apparatus includes: a frame having a first side that has a first connecting unit; a lighting module for generating light, the lighting module having a second connecting unit connected to the first connecting unit of the first side of the frame such that the lighting module is mounted to the first side of the frame; and two optical sensors mounted on the frame and disposed respectively at two corners of the frame, each of the optical sensors sensing the light generated by the lighting module.

Abstract: A motion-detecting module for combining a light-emitting function and a light-sensing function together includes a chip unit, a cover unit, and a light-guiding unit. The chip unit has a PCB, a light-emitting chip, and an image-sensing chip, and both the light-emitting chip and the image-sensing chip are electrically disposed on the PCB. The cover unit covers the light-emitting chip and the image-sensing chip. The cover unit has a receiving space for communicating the light-emitting chip and the image-sensing chip, a first opening for exposing the light-emitting chip, and a second opening for exposing the image-sensing chip. The light-guiding unit is disposed under the cover unit, and the light-guiding unit at least has a first refraction surface, a second refraction surface, a third refraction surface, a fourth refraction surface, and a reflection surface.

Abstract: A motion-detecting device for reducing assembly tolerance includes a connection unit, a light-emitting unit, an image-sensing unit and a positioning unit. The connection unit has a first fixing portion formed on one side thereof and a second fixing portion formed on another side thereof. The second fixing portion has a receiving space and a through hole communicating with the receiving space. The light-emitting unit is fixed in the first fixing portion of the connection unit for generating a projection beam. The image-sensing unit is received in the receiving space of the second fixing portion for capturing images. The positioning unit is positioned over the receiving space of the second fixing portion and electrically connected to the image-sensing unit. The transparent base is disposed under the connection unit and mated with the second fixing portion of the connection unit.

Abstract: The invention provides an optical sensor package. The package comprises a circuit board, an image sensor module and a packaging cap. The image sensor module electrically connects to the circuit board; the packaging cap is mounted on the circuit board and integrally packages the image sensor module. Hereby, the new architecture of the invention is not complex and its volume is small. The cost of the package is low, and the invention has the functions of electrostatic discharge and waterproofing; besides, the packaging cap can integrally package the image sensor module and a light-emitting module.
