A signal synchronism detecting circuit comprises a receiving circuit receiving a serial data including data bit groups each composed of a predetermined number of continuing bits and delimiter bit groups each composed of a predetermined number of continuing bits for delimiting the data bit groups from one another, a detecting circuit for obtaining an exclusive OR between continuing bits of the received serial data, so as to detect the delimiter bit group, and a serial-to-parallel converting circuit for serial-to-parallel converting the received serial data on the basis of the result of the detection of the delimiter bit group by the detecting circuit.
