信端末装置。 A transmitting/receiving terminal device that receives a transmitted signal in a format in which a plurality of pairs of an identification code and a message code are inserted between synchronization codes, and transmits a signal with a predetermined code, and detects that the received synchronization code is locked. The first signal generating means generates a lock output for a period slightly longer than the reception synchronization code period in response to the reception synchronization code while the reception synchronization code is locked, and the reception synchronization code matches a preset synchronization code. a second signal generation means that generates a coincidence detection output when the lock output and the coincidence detection output are detected; an AND operation means that performs an AND operation using the lock output and the coincidence detection output; 1. A transmitting/receiving terminal device comprising: transmission control means for maintaining a transmission state of a predetermined code for a period of a message code length paired with a specified identification code.
