An object of the present invention is to provide a control device for controlling the swing action of an air conditioning apparatus and improving the level of comfort within a room. A control device (4) is a control device (4) for controlling a swing action for causing flaps (22a-22d) of an air conditioning apparatus (1) to swing up and down, the control device (4) comprising an operation mode determining section (41a), a swing pattern storage area (42), and a control command generator (41 e). The operation mode determining section (41a) determines at least an air-cooling operation mode and an air-warming operation mode, which are operation modes of the air conditioning apparatus (1). The swing pattern storage area (42) stores a plurality of swing patterns which are varieties of information pertaining to the swing action. The control command generator (41 e) generates a control command of the air conditioning apparatus (1) on the basis of the swing pattern that corresponds to the result determined by the operation mode determining section (41a) from among the plurality of swing patterns.
