Abstract: A keyboard and a key structure capable of displaying instant image thereof are provided. The key structure includes a display unit, a circuit membrane, an elastic member, a key seat, a first supporting frame, a second supporting frame, and a translucent keycap. The first supporting frame has two first arms and two axle portions. The ends of the first arms are slidably disposed on an accommodation portion of the key seat. The second supporting frame has two second arms and two linking holes. The ends of the second arms are pivotally connected to the accommodation portion. The linking hole is elongated-shaped. When the translucent keycap is not pressed, the axle portion abuts against one hole-end of the linking hole. When the translucent keycap is pressed, the axle portion abuts against another one hole-end of the linking hole.

Abstract: A bracket that includes a fixing seat and three supporting assemblies is provided. The fixing seat includes three engaging portions, each of which includes multiple first engaging structures. Each supporting assembly includes a fixing assembly, a sliding member, and an engaging member. One end of the fixing assembly is pivotally connected to the engaging portion. The sliding member is sleeved around an outer periphery of the fixing assembly. The engaging member is connected to the fixing assembly. When the sliding member slides relative to the fixing assembly, the sliding member can push against the engaging member, such that a second engaging structure of the engaging member is engaged with the first engaging structure. Further, a second retaining structure of the sliding member can be engaged with a first retaining structure of the fixing assembly for limiting a movement range of the engaging member and the fixing assembly.
