Abstract
In an operating part located at the center of an elastic board having a first and a second pairs of strain detecting elements, a through hole is provided. The through hole is fitted with an operating rod allowing the up and down movement. Underneath the operating rod, a push button switch is provided. A cursor on a display screen may be moved by horizontal manipulation of the operating rod, and the switch may be put into action for input by vertical manipulation of the operating rod.
