Abstract: A waterproof button mechanism of a computer input device has a bottom case having a coding module and at least two micro switches mounted therein and connected with the inner case. Two mounting holes are formed on a front end of the inner case to respectively correspond to the two micro switches on the bottom case. Two waterproof assemblies are respectively mounted on the two mounting holes. A top cover is mounted on the inner case. Two slots are formed through a front end of the top cover. A button is movably mounted in the slot and a front end of the button corresponds to the waterproof assembly. When the button is pressed down, the input device is operated by triggering the micro switches through the waterproof assembly. The waterproof mechanism is waterproof function to be added without sacrificing easy customization of appearance.

Abstract: A web camera has a bracket, a camera module, and two connecting assemblies. The bracket has a front bracket and a rear bracket mounted pivotally to each other. The camera module is mounted pivotally in the bracket. The connecting assemblies are mounted respectively in two sides of the bracket to mount the front and rear brackets pivotally to each other and to mount the camera module pivotally in the bracket. Each connecting assembly has a torsion spring respectively connecting securely to the front and rear brackets to provide clamping force to the bracket. Therefore, the web camera can be clamped at a desired place.

Abstract: The present invention relates to a two-way cable winding reel. The reel includes a housing, a rotator, a worm spring, and a cable. The rotator has several protrusions on one side, and the housing has a movable stopper. One end of the stopper forms a pawl that extends between any two of the protrusions. The pawl permits rotation of the rotator in a first direction to extend the cable when a sufficient pulling force is applied to the cable, and prevents rotation of the rotator in a cable retraction direction so long as the pawl extends between the protrusions. The other end of the stopper protrudes through the housing such that a user may engage or disengage the stopper to cause the pawl to disengage from the protrusions and permit retraction of the cable to a desired length.
