The present disclosure provides a projection system and a light screen generating device thereof. The light screen generating device includes a movable carrier module, a first light-emitting module, and a second light-emitting module. The first light-emitting module includes a plurality of first light-emitting structures disposed on the movable carrier module. Each of the first light-emitting structures generates an invisible light screen, and the invisible light screens respectively generated by the first light-emitting structures are mated with each other to form a spliced invisible light screen for increasing light emission uniformity. The second light-emitting module includes a second light-emitting structure that is disposed on the movable carrier module and that generates a visible light screen parallel to and overlapping the spliced invisible light screen.

This invention provides a fastening assembly and a method for manufacturing the fastening assembly. The method for manufacturing the fastening assembly is used for an electronic apparatus. The electronic apparatus includes a first case. The method at least includes the following steps. A boss is embedded into a seat by hot melting to allow the boss and the seat to form a first fastening element, and the boss has a screwed hole. Then, the first fastening element is disposed at the first case by hot melting.

A laser indicator is secured on a rotating shaft of a sawing machine, on which rotating shaft a saw is fitted; the laser indicator consists of a base, an upper cover, a laser module, and a threaded adjusting element passed through a screw hole of the upper cover; the laser module is pivoted to the base, and subjected to elastic force of an elastic member; the adjusting element is pressed against the laser module such that orientation of the laser module can be adjusted by means of turning the adjusting element; therefore, if the laser beam emitted from the laser module fails to head towards exactly the same direction as the blade of the saw, the user is allowed to turn the adjusting element to adjust the laser module to a correct position.
