PURPOSE: A keyboard is provided to reduce the thickness by supporting a supporting plate, a membrane sheet, and a light emitting device printed circuit board (PCB) to a keyboard body unit through a mounting groove formed on the bottom of the keyboard body unit and to prevent the supporting plate, the membrane sheet, and the light emitting device PCB to be protruded over the bottom of the keyboard body unit. CONSTITUTION: A mounting groove of a keyboard body unit (11) is cut in order to arrive to the top of a supporting plate (12) from the bottom. An elastic body (51) is formed on a transparent material and is combined to the top of a membrane sheet (14). The supporting plate, the membrane sheet, and a light emitting device PCB (41) are supported to the keyboard body unit within the mounting groove and do not protrude over the bottom of the keyboard body unit. A light emitting device (42) is installed in the light emitting device PCB so that light of the light emitting device passes through a light guide hole (14b) of the membrane sheet and is guided to the upper side of the supporting plate. |
