Abstract

PURPOSE: To decide the kind of a device by folding an output which has been output from the device control unit, by use of the device, and discriminating the folded signal.
CONSTITUTION: A signal which has been generated from the control part 1 is input to the open collector circuits 4, 5 as an interface signal 13 through the NAND circuit 6. Whether an output of the open collector circuits 4, 5 is connected to the interface signals 11, 12 or not, is varied depending on the kind of a device. Accordingly, the kind of a device can be decided by returning the interface signals 11, 12 to the control part 1 through the NAND circuits 7, 8.
