Claim:
A keyboard with elevated keys, comprising: a foundation sheet; a plurality of key sets having a plurality of keys, wherein each of the keys has a key cap movably connected to the foundation sheet through a supporting mechanism and moves with respect to the foundation sheet between an elevated position and a depressed position; a plurality of guiding sheets, movably disposed on the foundation sheet and having a plurality of hooks and a track arranged in a first direction, wherein the distance between two neighboring guiding sheets is a first interval, and the guiding sheets move in a second direction from a first position to a second position; and a sliding member, movably disposed on the foundation sheet and having a plurality of protrusions extending into the tracks of the guiding sheets, wherein the distance between two neighboring protrusions is a second interval, the second intervals are unequal to the first intervals, and when the sliding member moves in the first direction, the protrusions move the guiding sheets in the second direction from the first position to the second position, such that the hooks contact the supporting mechanisms to sequentially depress the key caps of each key set from the elevated position to the depressed position.
