紙装置。 □A cassette that accommodates transfer paper, a paper feed roller that can be rotated forward and backward to feed the transfer paper sheet by sheet, and a pair of transport rollers consisting of two upper and lower 9-rollers that transport the fed copy paper.
A first sensor is provided between the cassette and the transport roller pair for detecting the feeding of multiple sheets, and a second sensor is provided in front of the transport roller pair for detecting the presence or absence of transfer paper in the transfer paper transport direction.
In response to a multi-sheet feed detection signal from the sensor, the rotation of the lower roller of the transport roller pair is stopped, and at the same time the upper roller is allowed to freely rotate, and the paper feed roller is reversed to leave the transfer paper in contact with the lower roller. A paper feeding device for a copying machine, characterized in that it is configured to return other multi-fed sheets into a cassette. □
