Claims

[Claims for Utility Model Registration] A cassette that has a foldable placement plate on which copy paper is placed and that can be inserted into and removed from the main body of an image forming apparatus, and when this cassette is inserted, a swingable placement plate pushing member for pushing up the placement plate; and a feeder located on the upper surface of the copy paper housed in the cassette and movable between a position in which it contacts the copy paper and a position in which it separates from the copy paper. In the paper feeding device, the paper feeder is equipped with a paper roller, and is configured such that when the cassette is inserted into or removed from the device main body, the cassette is lifted and disengaged from the engagement portion in the main body. A follower member is installed in the movement path of the cassette in the image forming apparatus and swings by interfering with a protrusion fixed to the side of the cassette, and a follower member rotates at a position near the mounting plate pushing member. a release member that is movable in a direction in which it can be engaged with and disengaged from the placement plate push-up member depending on the direction of rotation, and that is set in a flat position to engage with the placement plate push-up member; , a swingable drive member that is integrated with the support portion of the paper feed roller and sets the contact position of the paper feed roller with respect to the copy paper during normal operation; and a swing end of the follower member and a drive member that a swinging end, and a member that is respectively coupled to the release member and transmits the swing of the follower member, and the release member and the release member stop the movement of the follower member when the follower member rides on the overhang of the cassette. The transmission is transmitted to the driving member, and the engagement between the releasing member and the placing plate pushing up member is released, and the pushing up of the placing plate is released and the placing plate is retracted, and the driving member brings the paper feed roller into contact with the copy paper. A paper feeding device characterized in that a posture setting is canceled and a paper feeding roller can be retracted.
