This utility model relates to a multi-light source input device, comprising a substrate, on which a light source assembly, a photosensitive assembly, a triggering mechanism, and a filter element are disposed. An optical channel is provided between the light source assembly, the photosensitive assembly, and the triggering mechanism. The light source assembly and the photosensitive assembly are located on the same side of the triggering mechanism. The filter element is either a reflective filter element or a transmissive filter element. The reflective filter element can be triggered by the triggering mechanism; for the transmissive filter element, the triggering mechanism includes a reflective element, and the filter element is located between the reflective element and the light source assembly. The reflective element has a first state and a second state. This utility model connects multiple triggering mechanisms in parallel on one optical channel. The light emitted by the light source assembly exits and returns within the same optical channel, significantly reducing the length of the optical channel and facilitating miniaturization of the input device. This utility model can also connect more triggering mechanisms on one optical channel, and when used in a keyboard, it can also achieve multi-key rollover within a set of keys.

The utility model relates to wet tissue packaging barrel technical field, and disclose a kind of packaging barrel for containing clean wet tissue, including barrel body, barrel body top is provided with taking mechanism, and barrel body bottom is provided with change material mechanism, and taking mechanism includes top cover subassembly, extraction subassembly and closure subassembly, top cover subassembly is set in barrel body top, extraction subassembly is set in top cover subassembly inner ring, and closure subassembly is set in top cover subassembly top. The packaging barrel for containing clean wet tissue, by the taking mechanism being set, wet tissue is placed in barrel body, first time is taken and uses wet tissue to be extracted by empty slot, then wet tissue can be buckled in the clamping groove of top plate top, and it can be extracted every time, and it is convenient to save dosage extraction, and user can open or close closure lid by the way of the tab, after closure lid is closed, collar and snap ring are positioned to closure lid by mutual cooperation, so that wet tissue in barrel body does not lose internal moisture when not using, and the storage time of wet tissue is improved.
