Abstract
An air conditioner includes an air suction port and an air outlet port. Sets of horizontal blades extend across respective ports and are rotatable about horizontal axes for opening and closing the respective port. Each set of blades includes lugs movable in an inclined slot formed in a respective linearly movable cam member to produce rotation of the blades in response to linear movement of the cam member. Each lug is also movable in a curved slot of a separate guide member to guide the rotational movement of the blade. Each inclined slot includes a linear inclined section and may include vertical extensions at each end of the linear section. The cam member can produce different angles of rotation of the blades so that, due to an optical illusion, the blades appear to a viewer to have been rotated by equal angles.
