摘要： A sheet feeding apparatus comprising a sheet supporting device for stacking and supporting sheets, a sheet supplying device for feeding out the sheets supported by the sheet supporting device, a separating device for separating the sheets fed by the sheet supplying device one by one, a back tension releasing device for not acting a back tension on the sheet separated by the separating device, and a double feed preventing device, which is insertable into and retractable from a sheet feeding path for the sheet separated by the separating device. When the back tension is released by the back tension releasing device, the double feed preventing device is inserted into the sheet feeding path, thereby preventing the double feed of the sheets.

摘要： An apparatus of the present invention includes a first guide supported by a cover body in such a manner that the first guide can swing around a hinge with respect to the main body of the apparatus and a second guide provided on the apparatus main body. The first guide is supported in such a manner that it can move with respect to the cover body. When the cover body swings so as to open a sheet conveyance path, a site of the first guide on the side of the hinge swings with respect to the cover body in such a direction so as to separate from the second guide.

摘要： A sheet obliquely conveying apparatus is provided with a pair of sheet conveying rollers including a forwardly and reversely rotatable drive roller and a follower roller rotatable in contact with the drive roller, and bearing structure for rotatably supporting the shaft of the follower roller. The dimension of the bearing portion of the bearing structure which supports one end of the shaft of the follower roller is greater generally along the direction of conveyance of a sheet material than the dimension of the bearing portion of the bearing structure which supports the other end of the shaft of the follower roller. The apparatus is further provided with a resilient device generally parallel to the direction of conveyance of the sheet material for pressing the shaft of the follower roller.

摘要： This invention relates to a sheet feeding apparatus having sheet carrying device unit for carrying sheets suspended by suspending unit, which is taken up by winding unit and thereby moves the sheet carrying device up and down to render the sheets fed from the topmost side of the sheets. Connection positions between the suspending unit and the sheet carrying device are located, in a direction perpendicular to a feeding direction of the sheets, at positions on a side of the sheet reference which is one end in the direction perpendicular to the feeding direction of the sheets, closer to the center of the sheets with respect to a position of a suspending original point of the suspending unit located over the sheet carrying device. The other connection positions between the suspending unit and the sheet carrying device are located, in a direction perpendicular to a feeding direction of the sheets, at a position on a side opposite to the side of the sheet reference, remote from the center of the sheets with respect to a position of a suspending original point of the suspending unit located over the sheet carrying device.
