摘要:
A display screen control apparatus for producing a plurality of control signals in response to pressing, tilting and rotating a single operation lever, the control signals being transmitted to control circuitry for controlling the position of a cursor on the display screen in response to the control signals. The display screen control apparatus includes a base upon which are formed a plurality of control switches, the operation lever being resiliently positioned over the control switches such that pressing the operation lever actuates a first control switch, tilting the operation lever actuates one of a plurality of second control switches, and rotating the operation lever actuates one of two third control switches.
