Abstract: A laser-optical position detecting module with a laser as a light source is disclosed, which includes a laser mode conversing assembly, having a laser source capable of emitting a time-modulated laser beam; a laser mode conversing unit, used to expand the time-modulated laser beam to a two-dimension sensing plane; a drive control unit, adopted for driving the laser source to emit the time-modulated laser beam; and a detector matrix. The laser mode conversing unit has a phase delay device and a passive optical device capable of reflecting the light; so that, through the laser mode conversing unit, the laser-optical position detecting module can expand the light emitted by the laser source to the two-dimension sensing plane without using any other mechanical scanning.

Abstract: A light emitting key structure is provided. The key structure includes a base, a reflective sheet, a circuit board, an elastic member, a linkage mechanism, and a key cap sequentially disposed one on another in order. The reflective sheet is disposed on the base. The circuit board is made of a light guide material. At least one light source is bonded to a lateral side of the circuit board. The circuit board, together with the light source bonded to the lateral side thereof is disposed on the reflective sheet. The elastic member is directly coupled to the circuit board. The key cap is featured with a light transmission characteristic. Therefore, in operation, the light emitted from the light source can be directly guided into the circuit board, and then outputted from the light transmissive key cap, thus achieving the light emitting effect.
