Abstract:
The present invention has an object enabling stable data communication hard to perform a malfunction in a simple circuit configuration which can miniaturize a system and does not need any strict accuracy by executing data communication in a connection using two terminals or less. The present invention is featured by being related to a data carrier device including a signal terminal for performing signal input from a data carrier driving device. The data carrier device includes a data communication circuit receiving an input of a pulse having a part having a different duty ratio and a pulse frequency constant on the whole from the data carrier driving device through the signal terminal to generate a data signal.
