A folding keyboard is set forth with a numeric keypad, and one fold line located between the edge of a standard continuous space bar and the edge of the numeric keypad. Preferably, the keyboard further includes left and right top cases, supporting inexpensive rubber dome switches, left and right bottom cases, membrane sheets with circuit traces connecting keyboard electronics to contact points under each key, two hinge screws or rivets (or the like) that hold the left and right sides of the keyboard together at the hinges, and a locking mechanism to keep the case closed when folded shut.

A keyboard having an improved function key section and an improved editing section. A row of keys is located behind the alphanumeric section. The row of keys includes individual predefined command keys. The groupings of the predefined command keys may be made based on the functionality of the keys, their use on common applications or programs, and/or other by other grouping techniques. Further, the keys within each group may be ordered based on chronological order of use, frequency of use, or by a correlation to a graphical toolbar. Each of at least two adjacent groupings of keys in behind the alphanumeric region consists of exactly three keys, and each of at least three adjacent key groupings in the entire row consists of exactly three keys. The keys are each capable of functioning as predetermined command keys in a first mode and standard function keys in a second mode. A Function Lock key may be used to convert these keys from their use in one mode as their predefined command keys to another mode where they become standard function keys. These keys are preferably primarily labeled as their command keys and secondarily labeled as standard function keys. The editing section includes a first key cluster having a plurality of keys forming a two dimensional array of cells. At least one key occupies a single cell and a Delete key occupies at least two cells. A key cluster is located behind and spaced from the editing section, and consists of an Undo key and a Redo key.

A keyboard. A keyboard subassembly is disposed on a base and moves between a first position and a second position. The keyboard subassembly provides a first angle of elevation when in the first position, and a second angle of elevation when in the second position. The first angle of elevation is less than the second angle of elevation.

In a foldable keyboard, a cover member (100) includes a cover part (101) provided with a cover plate (104) and a pair of supporting elements (102, 103) formed on both ends of the cover plat. The supporting elements are each formed with a first slot (117) and a second slot (118). A support screw (123) passes with play through the first slot and is fixedly received in a baring hole (13A) of a bearing member (13) formed in a corner (12B) of a first keyboard unit (3) and a support screw (124) passes with play through the first slot and is fixedly received in a support hole (121) of a first base plate (5) formed in a corner (12A). A support screw (125) passes with play through the second slot and is fixedly received in a bearing hole (17A) of a bearing member (17) formed in a corner (16B) of a second keyboard unit (4) and a support screw (126) passes with play through the second slot and is fixedly received in a support hole (120) of a second base plate (8) formed in a corner (16A).
摘要:
A waterproof keyboard is provided, which has keys, scissor frames, elastic layer bodies, a membrane circuit board, a support plate and a bottom plate, wherein the bottom board is disposed with a plurality of stamped nodes, which are corresponded by apertures disposed on the support plate. The means of riveting is used for riveting the bottom plate and the support plate, such that no apertures can be found on the bottom plate, so as to prevent liquids poured on the keyboard by accident from infiltrating down to the motherboard underneath the bottom plate, thus assuring that the motherboard is not damaged thereby. As a result, the computer can be kept operable. Also the membrane circuit board is mounted on top of the support plate, thus rendering the overall structural assembly easier and such overall structure more stable.

An apparatus includes a display and a keypad. The keypad has a plurality of keys, a first subset of which are adapted to define a first arrangement of keys, and a second subset of which are adapted to define a second arrangement of keys. Further, the apparatus includes a light provision arrangement that has at least one light source. A controller coupled to, and adapted to control the operations of, the light provision arrangement, to highlight the first and second subsets of keys during a first and a second mode of operation respectively. The keypad has a first and a second different relative operational disposition to the display, in said first and second modes of operation respectively.
