A signal processor unit related to the frame communication, wherein a unit communication period is allocated, and each communication device starts communicating operation associated with the next frame after recognizing an end of frame communication based on a received signal. The signal processor unit includes a period detection section to detect a period when a frame communication is being performed, a pattern detection section to detect a first signal pattern recognized as an end of the frame communication from the received signal, and an output processing section to output the received signal to a connected controller. Upon detection of the first signal pattern during the period when a frame communication is being performed, the signal processor unit instructs the controller to restrain startup of communicating operation associated with the next frame until the end of the period when the frame communication is being performed, thereby preventing the frames from being transmitted from a plurality of communication devices at the same time to ensure normal communicating operation of the next frame.
