The band 44 is supported in association with the printhead 54 by non-return cylinders 58,64 capable only of uni-directional rotation. Each cylinder 58,64 is provided with a rotary spring 76 which takes up any excess length developing in the band 44. Spring loaded rollers 98,110 at either end of the printing path support the band 44. Electrical indication is provided when one, the other or both of the cylinders 58,64 cease to take up excess length and when one, the other or both of the spring loaded rollers 98,110 also cease to take up excess length in the band 44.Type: GrantFiled: March 8, 1988Date of Patent: June 20, 1989Assignee: Unisys CorporationInventor: Gerard Chenest

Patent number: 4834563Abstract: A thermal ink-transfer printer is disclosed in which an ink donor sheet is wound on a supply reel. The ink donor sheet is drawn out from the supply reel and passes between a rotating drum and a thermal head and is then rolled round a winding reel. Printing paper is moved in a printing-paper transporting path formed between the rotating drum and guide means. The thermal head presses the ink donor sheet against the printing paper and heats the ink donor sheet to transfer the ink on the ink donor sheet to the printing paper. The ink donor sheet after completing the ink transfer is separated from the printing paper and rolled round the winding reel. The printing paper separated from the ink donor sheet is moved in the printing-paper transporting path. When the ink donor sheet during separation from the printing paper is erroneously drawn into a predetermined portion of the printing-paper transporting path, this erroneous operation of the ink donor sheet is detected by jam detecting means.Type: GrantFiled: May 8, 1987Date of Patent: May 30, 1989Assignee: Hitachi, Ltd.Inventors: Naohiro Ozawa, Toshihiko Gotoh, Junichi Shoji
