摘要： An electronic device has a cavity in which a stylus can be slidably inserted. The stylus has a retaining slot thereon. Being inserted in the cavity, the stylus firstly pushes a retainer to be moved resiliently. The stylus further presses on a stylus-releasing device that terminates the cavity, thereby engaging the stylus-releasing device in a stable configuration with a resilient force. Meanwhile the retainer inserts into the retaining slot of the stylus to hold and immobilize the stylus in the cavity. To extract the stylus, a short pressing action is exerted on the stylus, which disengages the stylus-releasing device from the stable configuration, thereby the stylus-releasing device exerts a resilient force on the stylus that is ejected partially out of the cavity to facilitate a grasp of the stylus.

摘要： A keystroke structure (3) for an electronic device which includes a shell (2) defining an opening (22). The keystroke structure comprises a cap (32) made of hard plastics such as ABS resin, a flange (34) fixed to a bottom of a periphery of the cap, wherein the flange is made of a material, such as rubber which is more elastic than that for forming the cap. The cap has a portion extending upward through the opening. A rod (42) extends downwardly from a bottom of the cap. A switch assembly (4) consisting of four first switches (44) for cursor direction control and a second switch (46) for “enter” control. The first switches are activated by the rod when the cap is titled, and the second switch is activated by the rod when the cap is vertically depressed. When the cap is titled to activate one of the first switches, the flange engage with a bottom face of the shell. Since the flange is made of resilient material, the engagement thereof with the shell will not cause the second switch to be also activated when the cap is titled to activate one of the first switches. Such a design is particularly advantageous when the electronic device has a reduced thickness.

摘要翻译： 一种用于电子设备的击键结构（3），其包括限定开口（22）的外壳（2）。 击键结构包括由诸如ABS树脂的硬塑料制成的盖（32），固定到盖的周边底部的凸缘（34），其中凸缘由诸如橡胶的材料制成，该橡胶更具弹性 比形成帽子。 盖子有一个向上延伸穿过开口的部分。 杆（42）从帽的底部向下延伸。 一个由用于光标方向控制的四个第一开关（44）和用于“进入”控制的第二开关（46）组成的开关组件（4）。 当帽被标题时，第一开关由杆激活，当帽被垂直按压时，第二开关由杆激活。 当盖被命名为激活第一开关中的一个时，凸缘与壳体的底面接合。 由于凸缘由弹性材料制成，因此当盖被命名以激活第一开关中的一个时，与壳的接合不会导致第二开关也被激活。 当电子设备具有减小的厚度时，这种设计是特别有利的。
