PURPOSE:To save kinds of signal transmission/reception circuit by connecting input/output of plural transmission circuits and reception circuits to plural connectors in multiple connection. CONSTITUTION:Input/output section of a counter-external device of transmitting leads S0-S3 at transmission circuit side and reception leads R0-R3 at reception circuit side is connected to a connector 34, and an input/output section of counter-external device of the transmission leads S0, S1 at transmission circuit side and reception leads R0, R1 at reception circuit side is connected respectively to connectors 32, 33. When an electronic circuit package of a signal transmission/reception circuit 31 is connected to an external device by using the connector 32, used similarly as a signal transmission/reception circuit 22 and used similarly as a signal transmission/reception circuit 23 by using the connector 34. Thus, the signal transmission/reception circuit is used in common to reduce number of kinds.
