Claims

[Claims for Utility Model Registration] A housing having a key guide on the upper side and a frame body on the lower side, a pair of elastic pieces provided on the frame body and having an engaging protrusion at the lower end, and a housing rotatably supported by the frame body. a key top having a key shaft inserted into a key guide so as to be vertically movable; a coiled buckling spring disposed between the key top and the actuator and always urging the key top upward; an upper case having a fitting hole into which the frame of the housing is fitted; and a lower case having a switching circuit formed with a switching portion that is switched and controlled by the actuator, and the key switch is actuated. The keyboard is configured to be detachable from the fitting hole of the upper case via a pair of elastic pieces having the engagement protrusions.
