Claim 8

An apparatus according to claim 1, wherein said paper receiving means includes a plurality of paper receiving trays, stacked substantially vertically and constitute said the paper receiving portions, respectively, and said feeding means includes a plurality of rollers, each roller being partly located above a corresponding one of the receiving trays when the feeding means is approached to said receiving means by said second moving means.

Claim 9

An apparatus according to claim 7, wherein each of said paper receiving trays has a side edge located on the side of the feeding means, a side wall standing at the side edge, and a plurality of notches formed in the side wall for partly receiving the rollers of the feeding means when the feeding means approaches the receiving means.

Claim 12

An apparatus according to claim 9, wherein said guiding means includes a pair of first parallel guide plates extending from the predetermined portion towards the paper receiving means, a pair of first movable parallel guide plates pivotally coupled with respective extended ends of the first guide plates, a pair of second parallel guide plates extending from the movable unit towards the predetermined portion, and a pair of second movable parallel guide plates pivotally coupled with respective extended ends of the second guide plates, the first movable guide plates being slidably fitted between the second movable guide plates.

Claim 13

An image forming apparatus comprising: a body having a fitting portion opening outside; means arranged in the body for forming images on image transfer materials; a discharge portion for discharging the image transfer materials, on which images are transferred toward the fitting portion; and a sorter for sorting the image transfer materials discharged from the discharge portion, said sorter including: means for receiving the image transfer materials, said receiving means having a plurality of receiving portions and being detachably attached to the fitting portion, the receiving portions being stacked in a predetermined direction at predetermined intervals; means for feeding the image transfer materials into the receiving means, said feeding means being movable in the predetermined direction along the receiving means; a first moving means for moving the feeding means to a position facing a desired one of the receiving portions; means for guiding the image transfer materials discharged from the discharge portion to the feeding means; and second moving means for moving, independently of said first moving means, the feeding means such that said feeding means approaches from said position to the receiving means when the feeding means feeds the image transfer materials into the receiving means, after said feeding means is moved to said position by said first moving means, said second moving means being movable together with the feeding means in said predetermined direction.

Claim 14

An image forming apparatus comprising: a body having a fitting portion opening outside; means arranged in the body for forming images on image transfer materials; a discharge portion for discharging the image transfer materials, on which images are transferred toward the fitting portion; and a sorter for sorting the image transfer materials discharged from the discharge portion, said sorter including: means for receiving the image transfer materials, said receiving means having a plurality of receiving portions and being detachably attached to the fitting portion, the receiving portions being stacked in a predetermined direction at predetermined intervals; means for feeding the image transfer materials into the receiving means, said feeding means being movable in the predetermined direction along the receiving means; a first moving means for moving the feeding means to a position facing a desired one of the receiving portions; means for guiding the image transfer materials discharged from the discharge portion to the feeding means; and second moving means for moving, independently of said first moving means, the feeding means such that said feeding means approaches from said position to the receiving means when the feeding means feeds the image transfer materials into the receiving means, after said feeding means is moved to said position by said first moving means, said second moving means being movable together with the feeding means in said predetermined direction.

Claim 15

An apparatus according to claim 1, wherein said second moving means includes a drive source movable together with the feeding means, for moving the feeding means toward the receiving means, and means for actuating the drive source when the feeding means is in a position facing a specified paper receiving portion.

Claim 16

An apparatus according to claim 9, wherein said second moving means includes an eccentric cam arranged on the movable unit and engaging the feeding means, and means arranged on the movable unit, for rotating the eccentric cam.
