Patent number: 5529408Abstract: A thermal transfer recording and correction method, in which a thermal transfer ink layer is placed in contact with a transfer-receiving medium and is heated by heat generating elements of a thermal head in a pattern corresponding to a recording signal, is improved by preheating the ink layer. The ink layer, which is characterized by a transfer initiation temperature, is preheated by the thermal head which is heated by a preheating means. When a region of the ink layer is then further heated by the heat generating elements, the temperature of that region has a maximum and a minimum both within a range extending from the transfer initiation temperature to about 40.degree. C. higher than the transfer initiation temperature. Since the maximum and minimum temperatures are within a suppressed temperature range, an erroneous image can be more easily peeled off the transfer-receiving medium.Type: GrantFiled: June 7, 1995Date of Patent: June 25, 1996Assignee: Canon Kabushiki KaishaInventors: Haruhiko Moriguchi, Kazuhiro Nakajima, Hiroshi Sato, Masato Katayama

Patent number: 5350247Abstract: A printer capable of completely erasing printed characters while reducing noise which may be generated during the erasure. After an erase key is manipulated and the holder member is moved to its erase position, a motor is energized and driven at a motor current level of I1 and I2 from a time t0 when the erasing operation starts. A print hammer strikes onto a printing paper through a type and a correction ribbon at a hammer speed of V1. Thereafter, motor current level of I3 is applied to the motor, so that the print hammer presses the printing paper at a contacting pressure of P1. In the subsequent erasure operation, the motor current level of I11 and I12, which are smaller than I1 and I2 in the first erasure are applied to the motor. Thus, the hammer speed when striking onto the printing paper by the hammer is lower than V1. Accordingly, contacting pressure of the print hammer onto the printing paper becomes P11, which is smaller than P1 of the first erasure.Type: GrantFiled: June 28, 1993Date of Patent: September 27, 1994Assignee: Brother Kogyo Kabushiki KaishaInventor: Masaya Funamoto

Patent number: 4724445Abstract: A thermal transfer printer erases previously recorded characters by applying heating energy of higher surface density than that used to originally transfer thermally fusible material onto a recording sheet. A thermal transfer tape made of a polyester film and a layer of thermally fusible material is interposed between a thermal head of the printer and the recording sheet at the position to be erased. The thermally fusible material has a higher adhering affinity for the polyester film than for the recording sheet at the higher heating energy level and thus fusible material previously recorded on the recording sheet adheres to the tape at the higher energy level. When the tape is pulled away from the recording sheet, the previously recorded character adheres to the tape and is pulled away with it.Type: GrantFiled: May 1, 1986Date of Patent: February 9, 1988Assignee: Alps Electric Co., Ltd.Inventors: Toshiaki Amano, Ikuo Hibino

Patent number: 4572687Abstract: Ribbon (22) in thermal printing has an outer layer which adheres to printed characters of intermediate temperatures, lower than printing temperatures. The printhead (7) has a column of electrodes (9) which sweep across the character area. Erase mode selector (16) causes erase of the same character twice, first at a temperature level moderately more than the normal erase level and one at a temperature moderately less than the normal erase level. Erasure in that dual mode is generally effective even for extreme conditions of paper, environment and other influences.Type: GrantFiled: July 31, 1984Date of Patent: February 25, 1986Assignee: International Business Machines CorporationInventors: Donald F. Croley, Stanley Dyer

Patent number: 4547088Abstract: The ink layer of a thermal transfer printing ribbon is overcoated with a hold-off layer which serves to make the resulting printing more easily correctable. The hold-off layer operates by preventing penetration by the ink layer into the substrate being printed upon.Type: GrantFiled: June 26, 1980Date of Patent: October 15, 1985Assignee: International Business Machines CorporationInventor: Meredith D. Shattuck

Patent number: 4545693Abstract: Ribbon (22) in thermal printing has an outer layer which adheres to printed characters at intermediate temperatures, lower than printing temperatures. The printhead (7) has a column of electrodes (9) which sweep across the character area. Lift-off is accomplished by the pattern control (40) controlling the current source (38) to provide rapid, square wave pulses displaced in phase 180 degrees at adjoining electrodes (9). The high level of the pulses is about that of the level at printing, and the pulses are sufficiently rapid so that their net effect is to raise the outer layer ribbon (22) to the intermediate temperature. At areas corresponding to underlines of characters, duration of the up period is longer. Good, long term reliability is achieved by the significant erase level being very close to the print level.Type: GrantFiled: October 11, 1983Date of Patent: October 8, 1985Assignee: International Business Machines CorporationInventors: John C. Bartlett, Alan E. Bohnhoff, Donald F. Croley, Stanley Dyer, Kenneth E. Edds, Frank J. Horlander, Donald W. Stafford

Patent number: 4472073Abstract: A cartridge for a typing ribbon and spools for a correcting ribbon are mounted on a common frame which can tilt about a spindle. In a lowered position of the frame the typing line behind a daisy wheel is visible. The frame is raised by a first stroke to the position shown to dispose the typing ribbon over the typing point on the platen. A longer stroke raises the correcting ribbon to the typing point and this longer stroke also actuates an automatic ratchet wheel and pawl type of feed mechanism for the correcting ribbon. The two strokes of the frame are controlled by a disc comprising two cam tracks with a common part and separate parts having different degrees of eccentricity relative to the common part.Type: GrantFiled: April 9, 1981Date of Patent: September 18, 1984Assignee: Ing. C. Olivetti & C., S.p.A.Inventors: Franco Valle, Pietro Musso

Patent number: 4453839Abstract: A thermal ribbon particularly suited to be used once for printing at one temperature and for lift-off correction at a lower temperature. The bottom, resistive layer is a blend of an aliphatic polyurethane and a urethane acrylic copolymer with conductive carbon black. The next layer is 1000 angstroms thick aluminum. The next layer is the release layer, of an ethylene organic acid copolymer, a low-melting material. The top layer is an ink layer containing ethylene vinyl acetate and polyethyacrylate. The resistive layer has a light dusting of graphite. Low print currents for both printing and lift-off correction are achieved.Type: GrantFiled: June 15, 1982Date of Patent: June 12, 1984Assignee: International Business Machines CorporationInventors: Hugh T. Findlay, Keith A. Jones

Patent number: 4426169Abstract: A lift-off adhesively erasable typewriter ribbon contains, in a pigmentatious layer on the substrate strip, in addition to the pigment and a resin binder, a halogenated hydrocarbon modifier containing at least 14 carbon atoms serving to embrittle the resin binder and facilitate transfer of the layer from the ribbon to the paper during the writing process and to allow clean and adhesive removal of print if a correction is required.Type: GrantFiled: September 1, 1981Date of Patent: January 17, 1984Assignee: Franz Buttner AGInventor: Heinz Hartmann

Patent number: 4413266Abstract: The technology encompassed by the practice of this invention includes apparatus for ink jet printing under the control of electronic circuitry and ink jet printing under the control of an operator, for example, a typewriter. Broadly, the technology presented in accordance with the principles of this invention utilizes an ink eradicator which removes indicia of the ink by chemical reaction. The character of the eradicator fluid is such that another fluid may be utilized either together therewith or separately to neutralize the residue from the chemical reaction so that printing can readily be accomplished in the location where erasure has occurred. Specifically, practice of this invention is contemplated with means that applies the eradicator fluid over the location on a surface where printing has occurred by ink jet droplets as well as over an entire area thereon within which there is ink jet printing for which a change is to be achieved.Type: GrantFiled: December 14, 1981Date of Patent: November 1, 1983Assignee: International Business Machines CorporationInventors: Ari Aviram, Zalata Kovac, Robert A.
