A mixing device 4 superposes a power signal from a power apparatus 2 on the discrimination signal from the discrimination signal generator 3 and feeds the superposed signal to a power supply output connector 5. An apparatus 6, to be fed with power, discriminates the discrimination signal included in the power signal supplied via a power supply input connector by means of a source type discrimination signal discriminating device 8 and feeds thus obtained discrimination signal to a power supply type detecting and informing device 10. This device 10 detects the type of the power supply 1 and feeds information thereon to a processing unit 11.
