PROBLEM TO BE SOLVED: To eliminate a nuisance of moving about in a room to turn-on/turn-off power source one by one by automating the turn-on/turn-off of the power source of an electronic equipment having an input of a digital audio signal. SOLUTION: When the electronic equipment main body 23 is automatically turned on/turned off, minute power is supplied always to a power source control part 22. The detection part 28 of the power source control part 22 out-puts a control signal to a power source control line 30, so that the power source of the electronic equipment main body 23 is turned on, when a digital pulse signal is inputted to a digital audio signal code 25. Further, the detection part 28 outputs the control signal to the power source control line 30, so that the power source of the electronic equipment main body 23 is turned off when the digital pulse signal is not inputted to the digital audio signal code 25. These times from the detection to the power source turn-on or from the detection to the power source turn-off may be set properly. |
