Abstract
A keyboard unit comprises a keyboard base and a number of key-tops. A switch in the form of a sheet is interposed between the keyboard base and the key-tops. The switch has a number of movable contacts arranged corresponding to the key-tops, and a number of stationary contacts opposed to the respective movable contacts. The key-tops are supported above the keyboard base by respective key-top support mechanisms such that they can move vertically. Each of the key-top support mechanisms includes first and second link levers pivotably connected to each other. The first link lever is made of a metal and has an elastically deformable pressing section that is formed integral therewith as one body. A number of elastically deformable load receiving sections are interposed between the respective pressing sections and the respective movable contacts.
