Claims

[Scope of Claim for Utility Model Registration] (1) A paper feeder that is equipped with a plurality of cassette loading sections each having a paper feeding means, and that has a paper discharge port at the top of the merging paper feeding path from the plurality of cassette loading sections. It consists of a paper desk, an image forming apparatus main body having a paper feeding cassette loading section on the lower side, and a paper feeding attachment that is loaded into the cassette loading section on the apparatus main body side so as to be replaceable with the paper feeding cassette, The cassette loading section on the apparatus main body side has an opening that faces the paper ejection port when the image forming apparatus main body is mounted on the paper feed desk, and the paper feeding attachment has an opening that faces the paper ejection port when the image forming apparatus main body is mounted on the paper feeding desk. An image forming apparatus comprising: a driven roller that constitutes a paper skew regulating means by a paper feeding roller; and a paper feeding path extending from the opening to the skew regulating means. (2) A paper feeding desk equipped with a plurality of cassette loading sections each having a paper feeding means and having a paper discharge port for a combined paper feeding path from the plurality of cassette loading sections at the top, and a paper feeding desk at the bottom side. The image forming apparatus is comprised of an image forming apparatus main body equipped with a paper cassette loading section, and a paper feed attachment that is inserted into the cassette loading section on the apparatus main body side so as to be replaceable with a paper feed cassette, the cassette loading section on the apparatus main body side An opening facing the paper ejection port is opened when the image forming apparatus main body is mounted on the paper feed desk, and the paper feed attachment has a paper feed roller of a cassette loading section on the apparatus main body side. a driven roller constituting a paper skew regulating means; a first paper feeding path extending from the opening to the skew regulating means;
An image forming apparatus characterized in that a paper feed opening is provided at the rear side in the loading direction of the attachment relative to the cassette loading section, and a second paper feed path is provided from the paper feed opening to the skew regulating means. Device.
