Abstract: A slim-type keyboard includes a first flexible layer, a pressed frame and a circuit board assembly. The first flexible layer includes plural pressed regions. The pressed frame includes plural cantilever strips. The circuit board assembly includes plural dome switches. The plural cantilever strips are covered by the first flexible layer. The pressed regions are aligned with the cantilever strips and the dome switches, respectively. When one of the pressed regions is pressed, the cantilever strip is pushed down to trigger the corresponding dome switch. Each cantilever strip includes a U-shaped groove and a suspension end. The U-shaped groove opens to the suspension end. Consequently, the tactile feel of pressing the cantilever strip is improved.

Abstract: A keyboard and a notebook computer with the keyboard are provided. The keyboard is installed on the notebook computer. The keyboard includes a membrane circuit board, a key frame, a key, a linking rod and a fixing plate. The linking rod is connected with the key frame. The fixing plate is disposed under the key frame. While the linking rod is rotated relative to the key frame to push the key frame, a position-limiting structure of the key frame is moved along a guiding structure of the fixing plate. Consequently, the key frame is limited to be moved in a first axial direction. Moreover, when the key frame is moved to a locked position at the same level with a keycap of the key, the keycap cannot be pressed down.

Abstract: A key structure includes a supporting plate, a movable plate, a keycap and a limiting structure. The supporting plate has supporting plate opening. The movable plate has a movable plate opening. The supporting plate is disposed over the movable plate. The keycap is disposed over the supporting plate. The limiting structure is disposed on the keycap and inserted in the supporting plate opening. When the movable plate is moved to a disabled position, the limiting structure is not aligned with the movable plate opening and the limiting structure in the supporting plate opening is stopped by the movable plate. Consequently, the keycap is not allowed to be moved.

Abstract: A keyboard device includes plural keycaps and a membrane switch circuit member. The membrane switch circuit member is disposed under the plural keycaps. The membrane switch circuit member includes a wiring board and plural separate covering pads. The wiring board includes plural first trace patterns and plural second trace patterns corresponding to the plural keycaps. The plural second trace patterns are disposed on the wiring board and separated from the plural first trace patterns. There is a gap between each first trace pattern and the adjacent second trace pattern. The covering pads are disposed over the wiring board. The plural covering pads are aligned with the corresponding keycaps and cover the corresponding gaps. The covering pad has a triggering trace pattern over the corresponding gap.
