PROBLEM TO BE SOLVED: To swiftly and reliably switch to an input from an external device desired by a user. SOLUTION: The input switching device comprises plural input terminals 2 to which external devices are connected; a switching circuit 3 which selectively switches among the input terminals 2 for inputting signals from one of the input terminals 2; a controller 4 which controls switching of the switching circuit 3; and an operating part 8 which commands switching operations. The controller 4 drives the switching circuit 3 according to the set order of priority by switching signals from the operating part 8 and selects an input terminal 2 which is high-priority. The input is switched to an input from an external device which is connected to the above input terminal 2. COPYRIGHT: (C)2005,JPO&NCIPI
