A controller system is disclosed. However, this remote controller system cannot collectively control home appliances having different communication methods. Therefore, when collectively controlling a plurality of home appliances, the user needs to operate each dedicated remote controller of the plurality of home appliances, and thus the operation time cannot be reduced sufficiently.

  Further, in Patent Literature 3, a plurality of infrared light emitting units are placed in front of each infrared light receiving unit of each home appliance, and each infrared light emitting unit is controlled to emit light based on home appliance operation data. A home appliance remote control system that controls and operates home appliances even from the outside where infrared rays from an infrared remote controller does not reach is disclosed. However, in this home appliance remote control system, home appliances with different communication methods cannot be controlled in a lump, and therefore, it is not possible to sufficiently reduce the user's operation when collectively controlling a plurality of home appliances.

  Patent Document 4 discloses a signal transmission device for remote control that registers a device to be controlled, and performs remote control on the controlled device when the user contacts the controlled device displayed on the screen. Has been. However, in this apparatus, since it is necessary for the user to operate each controlled device to be controlled on the screen, the operation is complicated for the user. Can not be reduced sufficiently.
