Abstract
A key module and a keyboard having the key module are provided. The key module includes a base, a scissor-type unit and a keycap. The scissor-type unit has a first frame and a second frame. The first frame has a connection shaft rotatably pivotally connected to a shaft hole of the second frame. The shaft hole has a travel distance therein for the shaft to move within the shaft hole along a predetermined direction. The first and second frames respectively have a first side pivotally connected to a pivot connection unit of the key cap, and a second side slidably connected to a restricting unit of the base. Through the above-mentioned design, the first frame can rotate with respect to the second frame, so that the keycap can move up and down with respect to the base.
