Patent number: 6155563Abstract: A sheet sorter includes an array of a plurality of sorting trays which are mounted on a sorter body and arranged in a vertical direction and a general-purpose tray which is mounted on the sorter body and is larger than each of the sorting trays in capacity so that it accommodates a larger number of sheets than each of the sorting trays. A tray drive mechanism provided in the sorter body moves up and down the sorting trays and the general-purpose tray so that sheets transferred by a transfer mechanism provided in the sorter body are selectively discharged onto the sorting trays or the general-purpose tray. The array of the sorting trays is positioned above the general-purpose tray. The sorting tray array and the general-purpose tray are normally held in a position where the sheet discharge port of the sheet transfer mechanism is positioned between the lowermost tray of the sorting tray array and the general-purpose tray as seen in a vertical direction.Type: GrantFiled: November 30, 1999Date of Patent: December 5, 2000Assignee: Riso Kagaku CorporationInventors: Takahiro Ono, Takeshi Kakinuma, Tetsunobu Shibata, Nobuyoshi Suzuki, Yasuhiro Fujimoto, Masahiro Ueda

Patent number: 5975521Abstract: A sheet discharging apparatus includes a conveyor provided at one side of the body of the apparatus, and sorter trays and a large capacity tray provided on the opposing side. Wings are provided each rotatable about a rotation axis, on a discharging side of the conveyor, and a projection is formed in the front side in the sheet conveying direction of each wing. The projection is brought into contact with an urging member provided at a frame of the container which is movable in upward/downward directions. When sorter trays are used, the urging member is separate from the projection, so that upper surface of the wing is below a conveying surface. When the frame and urging member are elevated to use the large capacity tray, the urging member presses the projection upward, and hence wings are elevated to be positioned upper than the conveying surface.Type: GrantFiled: April 17, 1998Date of Patent: November 2, 1999Assignees: Omron Corporation, Riso Kagaku Corp.Inventors: Takahiro Ono, Takeshi Kakinuma, Nobuyoshi Suzuki, Yasuhiro Fujimoto, Masahiro Ueda
