ABSTRACT:
A displayed viewing area switching device has a switch support, at least three button switches disposed separately in a radial manner on the switch support, each with operating buttons toward the center of the switch support, a manipulation lever having a plurality of manipulation projections corresponding to the operating buttons of the button switches a lever guide supporting the manipulation lever to slide radially, and a spring member having an elastic force resistant to the radial sliding motion of the manipulation lever. This configuration allows the manipulation projections to press the corresponding operating buttons by the radial sliding motion of the manipulation lever to generate movement signals moving the displayed viewing area in radial directions.
