<p>PURPOSE:To make a paper jam preventable from occurring, by making a sensor signal so as not to become a control failure even in case a noise is added to it in making a controller so as not to adopt abnormal data as the comparative value to the next data at a time when the abnormal data are detected in the paper feeding controller. CONSTITUTION:A resist motor 11 is started after the specified time from a pulse signal to be obtained out of an encoder of a sensitizer 12. When an abnormal change is produced in a signal out of a sensor 15 and a controller misconceives it is an off signal of the sensor 15, namely, a rear end of paper, even if whatever a signal of the sensor 15 may be, it is not recognized as an significant signal for duration of the specified time since the resist motor 11 has rotated, and the off signal entered afterward is set down to a rear end signal. And, after the separately set time, the resist motor 11 is stopped. Therefore, such a fear that the resist motor 11 has been stopped although the paper is still left remained in the resist roller is prevented from occurring.</p> |
