PROBLEM TO BE SOLVED: To achive a circuit configuration capable of discriminating existence of a recording paper detection sensor and a recording paper detection signal by one signal line. SOLUTION: A voltage divider means is connected with the recording paper detection sensor and the output of the sensor in parallel, and reading output voltage of the detection sensor by an analog/digital converter, thereby the state is discriminated.
