<P>PROBLEM TO BE SOLVED: To provide a selector device of an audio equipment in which burden on a user due to selection operation is reduced. <P>SOLUTION: One input terminal of a main switching device 13-1 and a sub-switching device 13-2 is alternatively connected to an output terminal. A control part 11 gives to a sub-switching device 13-2 a switching signal for switching sequentially an input terminal in each prescribed period. An analysis part 14 analyzes a signal obtained from the input terminal while the sub-switching device 13-2 selects an input terminal, and outputs information showing reproduction/non-reproduction to the control part 11. The control part 11 determines whether or not an audio equipment connected to which input terminal is in being reproduced based on the analysis result and the switching signal given to the sub-switching device 13-2, and in the case of detecting that the signal is changed from a non-reproduction state to a reproduction state, outputs a switching signal specifying an input terminal detected for the main switching device 13-1. Consequently, from the audio equipment connected to the input terminal, an audio signal is converted to sound so as to be emitted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
