Abstract: A sorting device for reversing a sheet fed from a printer and adhering the tag on the sheet, which includes rollers for conveying the sheet in a forward or backward direction, a sensor for detecting a position of the sheet conveyed by the rollers, a flapper for switching a path conveying the sheet based on a result of the detection by the sensor, and a tag affixing unit for passing the sheet when it is reversed and affixing the tag to the sheet when it is ejected, whereby the sheet may be reversed to be affixed by the tag, and easily and precisely sorted in reference to the affixed tag.

Abstract: A sheet sorting apparatus installed on a sheet discharge side of an image processing apparatus and adapted to paste a tag on a predetermined sheet discharged from the image processing apparatus is disclosed. The apparatus comprises a flapper for switching a path, in which the sheet is transferred to either a first path in which the tag is pasted on the sheet or a second path in which the tag is not pasted on the sheet; draw-out rollers for drawing out a band tape coated at one side edge portion thereof with a pressure-sensitive adhesive; a cutting portion for preparing the tag by cutting the band tape at a predetermined portion thereof; a pasting portion for introducing the prepared tag to a predetermined position with respect to the sheet and pasting the tag on the sheet; at least one receiving tray for receiving the sheet., on which the tag is pasted; and a controller for controlling movements of the flaper, the draw-out rollers and the cutting portion.
