PURPOSE: To take in any type of an output signal of an electronic device to be connected without confirming the type even when the output signal is an AC signal, a DC signal or a no-voltage contact.
CONSTITUTION: The take-in device 1 is made up of a couple of input terminals 2a, 2b receiving an AC signal, a DC signal or a no-voltage contact such as a big hit output signal of a pachinko board, a 1st rectifier 3 connecting to the input terminals 2a, 2b, a very small AC signal generator 4 connecting to the input terminal 2a, a filter 6 connecting to another input terminal 2b and passing only a very weak AC signal, an amplifier 8 connecting to the filter 6, a 2nd rectifier 9 connecting to the amplifier 8, and a photocoupler 10 processing output signals from the 1st rectifier 3 and the 2nd rectifier 9 in parallel and outputting a no-voltage open collector output.
