ることを特徴とする用紙反転装置。 In a copying machine equipped with a built-in paper reversing device and double-sided copying function, a forward/reverse rotating motor is used as the drive source for each drive roller in the paper transport system that transfers the paper from the pair of fixing rollers to the next paper transport path, and one of the motors The drive rollers are rotated at the same speed as the fixing speed of the pair of fixing rollers by the rotation of the pair of fixing rollers, and the drive rollers are rotated at a higher speed than the fixing speed by the rotation of the other pair, and the presence or absence of paper is checked in the paper conveyance path before and after the paper reversing device. A paper reversing device characterized in that a sensor for detection is arranged, and the rotation direction of the forward/reverse rotation motor is switched based on a detection signal from the sensor.
